How To Freeze A Frame In Clipchamp: Step

There are a lot of video editing techniques that help capture the audience’s attention, such as transitions, the use of green screens, animations, and text. But there is a little-known technique called freeze framing that can create drama and rivet your audience to a particular frame in the video.

But what is the freeze frame effect exactly and how can you use a video editor like Clipchamp to add the effect to your video? All this coming up!

What is ‘Freeze Frame’ in video editing?

Freeze frame – the name says it all! It’s a video editing effect that lets you freeze or halt the frame of a video clip for a short period of time. 

The freeze frame effect has been used in cinema a lot. From Martin Scorsese to Ridley Scott, directors have used the freeze frame technique to either break the fourth wall, add emphasis to a shot, or just introduce characters. But modern-day software and applications have leveled the playing field to a great extent. It’s possible now to use the freeze frame effect with very basic editing knowledge. 

That said, not every application offers an in-built freeze frame tool that you can simply apply to your video to pause it for a set duration. The same is true for Clipchamp as well, for now at least. Nevertheless, with a simple workaround, you can still get the freeze frame effect you’re looking for.

How to freeze a frame in Clipchamp: Step-by-step guide

Here is how you can freeze a frame in Clipchamp to get the desired effect:

1. Import your video

First things first, open Clipchamp and select Create a new video. 

Now, drag and drop the imported file into the timeline.

2. Find and capture the frame that you want to freeze

Now, preview your video and pause at the frame that you want to freeze. Take note of the time stamp of the frame.

If you’re finding it hard to get to the frame of your choice, zoom in on the timeline for better access.

Now, since Clipchamp doesn’t have a freeze frame effect to offer of its own, we’ll have to use a workaround.

To start with, run your video file in the media player of your choice. Then pause the video right on the frame that you want to freeze. Compare the two frames (in Clipchamp and your video player) side by side to see if the right frame is selected.

Then, open Paint from the Start Menu.

In the Paint app, press Ctrl+V to paste the captured frame.

3. Crop the captured frame

Then select the crop tool.

Select the rectangle. 

Crop the boundaries of the frame as closely as humanly possible and ensure that no extra black bars are present. 

This is the important bit here because we want to make sure that the frame is aligned with the actual video and doesn’t have unnecessary elements that will show up when we add it to our video. You may want to zoom in to get the best possible crop.

Then select File.

And save the frame at a convenient location. 

4. Import the frame to your timeline

Return to Clipchamp and select Import media.

Now, before we include this frame in our clip, we will have to first make space for it in the timeline. To do this, we’ll need to split the timeline video at the timestamp where the frozen frame will go.

Now that your video is split in two, drag the second part of the clip a little further out to the right to make space for the frozen frame image. 

Then drag and drop the imported image in this space.

Check the preview to see if the frozen frame and the video are aligned. If not, go back and re-crop the image so that it aligns as well as it can and import that again. 

Trim the frozen frame image to the desired duration and then join all the clips together so there are no breaks in between. 

Check the preview to see if the freeze frame effect looks the way you want it to.

5. Export your video

Select your quality.

And just like that, you’ve created and exported your video with the freeze frame effect.


Let’s take a look at a few commonly asked queries about the freeze frame effect and Clipchamp.

Does Clipchamp have the freeze frame effect?

Unfortunately, Clipchamp does not have a freeze frame effect. However, there is a simple workaround to achieve the same result. Refer to the guide above to know more.

How do I freeze a frame of a video?

If the software you’re using doesn’t have a freeze frame effect, then you will have to resort to a workaround. In brief, you will have to note down the timestamp of the frame that you want to freeze, run the video in a media player, pause it at that second and screenshot it. Thereafter, crop the screenshot in a software like Paint and save it. Finally, split your video in the timeline at the timestamp, import this cropped frame to your timeline in between the clips, and connect all the clips together. The result would be a succession of your video, the frozen frame, and the rest of your video which gives the freeze-frame effect. 

What is the purpose of the freeze frame effect?

The purpose of the freeze frame effect is to pause the video at a single frame for a set duration and then continue playing the video. The frozen frame works to accentuate the subject and call attention to it. 

We hope you were able to freeze a frame in your video using the workaround given in this guide. Even though Clipchamp doesn’t have an in-built effect that can achieve the same, with a little bit of creativity, you can achieve the freeze frame effect for any video in Clipchamp. 


How To Train Your Seo Team: A Step

If you’re a solo SEO professional, then training is easy.

The only thing needed is your commitment to learning new things on a regular basis.

However, as soon as you hire one more person to help with your SEO efforts, you have a team, and transferrable training becomes a necessity.

And if you’re managing an SEO team for an enterprise site but have no system set up for training your team, you’re already in trouble.

Because you already have plenty to do as a busy SEO professional, your training program needs to be:

Easy to implement.

Scalable as your teams and site needs grow.

This guide will give you a way to start an effective and easy-to-expand training program for onboarding new team members and improving the skills of your existing team.

Why You Need an SEO Training Program

Over the course of my career in several different agencies and now with a major SEO platform, I’ve observed that many SEO teams – even some at the biggest brands in the world – don’t have systematic training programs.


I suspect the biggest reason by far is time.

SEO professionals are already so busy that setting up a training program is just one more task.

It’s also harder to link to the things on which they will be evaluated.

So why should SEO team managers invest in building a training program?

It’s because:

Success in SEO is directly proportional to not only the skills but the knowledge of the SEO practitioners.

SEO changes rapidly – your team needs to be kept up to date.

A programmatic approach to training ensures uniformity of knowledge and standard procedures across your team.

You’re almost certainly doing training anyway, just not efficiently.

In short, training your SEO team is not optional.

It’s about how efficiently and effectively you’re doing it.

Here’s how to build an efficient and effective SEO training program while still having time to actually do SEO.

Step 1: Outline Training Essentials

Before you start creating or implementing an SEO training program, you need a plan to make sure you’ve covered all the essentials in a logical order.

At this point, your plan doesn’t need to be more than an outline.

Simply map out all the elements of SEO and your organization’s approach to it that you consider must-know for your team.

I want to emphasize that your plan should include both SEO knowledge, as well as your unique philosophy and standard operating procedures.

The latter should not be skipped because how your team does SEO is just as important as what they do.

What that outline contains will vary from one SEO manager to another, but here’s an example of a suggested course outline:

As you develop your training program you can flesh out the details of that outline more.

Step 2: Decide Your Training Medium

There are many different ways you can present your training to your team.

Which is best will depend on your own style and how you think your team learns best.

Here are some options.

Live Sessions

This is close to the traditional classroom approach.

Set up a schedule of regular team meetings devoted to training, either in person or remote by video conferencing.

As the manager (and presumably most experienced SEO pro on your team), you’ll probably lead most of the early sessions.

Over time, it is wise to assign sessions to other team members.

This lessens your burden and also serves as a great learning experience for others since the best way to learn something is to teach it to someone else.

Keep each session tightly focused on one main point.

People remember only a fraction of what they hear, so don’t try to cram too much into any one lesson.

If you use a deck to present each lesson, be sure to send it out to the team afterward for future reference or designate a central location where the decks are available for everyone.

Record each session.

Along with the presentation decks, these recordings become the basis of an ongoing training program that new hires can work through on their own.

Online Course

If you’re a bit more ambitious, you could make use of an LMS (Learning Management System) to build a self-guided course of lessons available online.

Also, learning can be self-paced with little further use of your time.

A big time investment in upfront work to design the course.

A lack of interaction with learners.

Existing Documentation

The “quick and dirty” way to build a training program is using documentation you’ve already created and stringing it together in a course of study.

This only works if you’ve been creating and updating content about SEO on a regular basis.

(You could also make use of third-party content, as long as your confident of its quality and fit for your organization.)

The idea here is to set up a course outline and have each lesson link to relevant blog posts, videos, decks, or other content.

Your only other investment here might be to set up quizzes and tests or other evaluative mechanisms if you want some accountability for what has been taught.

Step 3: Start a Regular Training Schedule

No matter which of the methods above you decide to employ, I highly recommend setting up a schedule for the training course and requiring your team to stick to it.

Otherwise it’s far too easy for the normal busyness of everyday SEO to cause procrastination and delay of training completion.

A session or lesson per week is probably sufficient for the live sessions approach.

For the online course or existing documentation approaches, set a series of deadlines, but allow the students to self-pace within those deadlines.

Step 4: Establish Evaluation & Accountability

While not absolutely necessary, having some mechanism for evaluation and accountability will help increase the effectiveness of your training program.

There are several approaches you can take.

Tests & Quizzes

This is the most traditional approach.

I suggest using non-graded quizzes immediately after each lesson to help reinforce and correct learning, with periodic tests to establish how much the learning has stuck.

Advantage: Immediate feedback and relatively easy to set up.


Design either simulated or “real world” projects where the student has to demonstrate application of the lesson.

For example, after a keyword research lesson the student has to find ten new keywords a site should be targeting and explain why.

Advantage: Intensely practical.

Work Monitoring

For some period of time after a given lesson, monitor the work of the team mate that relates to the lesson and look for signs of implementation of the principles learned.

Be sure to meet with the student periodically for feedback.

Advantage: Totally real-world demonstration of actual learning.

Wrapping Up

Whichever evaluation method you choose, make sure your approach is toward reinforcing learning, not a “gotcha” to find out who did poorly.

Place the emphasis on practical application, not just memorization of vocabulary and facts.

Be sure to have a plan to follow up on learning and reinforce where necessary.

Make the training and its effective application a part of an employees regular review process.

How To Get Verified On Twitter: A Detailed Step

Have you been a Twitter user for a long time? Garnered a decent following? And are now wondering how to get verified on Twitter? Well, you have come to the right place. After a prolonged 3-year hiatus, Twitter recently restarted its verification program and now lets users apply for verification to get the blue tick. Many Twitter users consider the company’s blue checkmark the gold standard for being a notable personality on the platform. So in this article, we will talk about the basic requirements to get verified on Twitter, the steps involved to apply for verification, and some helpful tips to easily get verified on Twitter in 2023.

Get Verified on Twitter (Updated May 2023) Twitter Verification Eligibility Criteria

To be eligible to apply for the blue tick on Twitter, your account should come under one of the following six categories:


Companies, brands, and organizations

News organizations and journalists


Sports and gaming

Activists, organizers, and other influential individuals

Some common factors across all categories include having a public Twitter account and having three or more media references within the past six months. In addition, Twitter requires companies, brands, organizations, and activists to have their follower count in the top .05% of active accounts located in the same geographic region. You can read more on Twitter’s criteria for specific categories on the company’s support page.

How to Apply for Twitter Verification

1. Open the Twitter app and tap on “Settings and Privacy” from the hamburger menu on the left. From here, tap on “Account” to access your account settings.

2. You will now see an option titled “Request Verification”. Tap on it to access the verification settings page. If you don’t see it, you will have to wait for a while because Twitter is still in the process of rolling it out. From the page that appears, choose the appropriate category for your account.

3. You should now choose a method to verify your identity. You will need to upload a government-issued ID, add an official business email address, or an official website that directly references your Twitter account. Pick the verification method that best suits you, and then submit your application.

Note: If you are concerned about your privacy, Twitter mentions that it does not get or store a copy of your government ID on an official FAQ page. The company relies on a trusted third party to “verify the authenticity of your ID” and decide whether your account is eligible for verification or not.

4. Once you have submitted the application, you will see a confirmation screen similar to the one you can see below.

Can I Reapply for Twitter Verification, If Rejected?

Now, let’s say you applied for verification on Twitter and didn’t manage to secure the blue tick on the first try. What should be your next move? Well, don’t be disheartened if you fail on the first attempt. You can reapply to get verified on Twitter.

On its official FAQ page, Twitter states you can “reapply for verification 30 days after rejection if you feel that your application should not have been rejected.” Also, there is no restriction on the number of times you can apply for verification.

That means you can essentially apply for verification every 60-odd days. We came to that number by assuming that Twitter gets back to you with your application status in 30 days, and then you have to wait another 30 days to reapply. Ultimately, you can apply to get verified on Twitter almost 5 to 6 times a year, barring that new applications are not on pause.

Best Tips to Get Verified on Twitter

Complete and Optimize Your Twitter Profile

Applicants must have filled in all the details in their profile, including the profile name, profile picture, cover photo, and bio. In the user bio, it is always wise to add how the general public should recognize you. This could be a job title or notable achievement.

For example, my colleague Anmol’s Twitter profile clearly shows his name, profile and cover photo, and the job description. It is always a good idea to include the @account name of your employer in the bio. You can also include links to your blog posts or any mentions on the web on your profile.

Make Sure Your Account is Active

Twitter requires verified accounts to be active on the platform. You must have at least logged into the account in the past six months. While you are at it, make sure you tweet regularly and engage with other Twitter users through tweet replies and DMs. It sounds like a simple tip but will greatly help you build a brand and get one step closer to getting verified on Twitter.

Build Credibility on Twitter

Confirmed Email Address and Number

You should have a confirmed email address or phone number for security reasons. In addition, we would recommend enabling two-factor authentication for Twitter to add another layer of security to your account.

Follow Twitter Rules

This might seem obvious, but Twitter requires applicants not to have had a 12-hour or 7-day lockout for violating the Twitter Rules in the past year.

Steps to Get the Blue Tick on Twitter

While you are here, check out the best Twitter tips and tricks to elevate your social media experience. You should also learn how to use Twitter Fleets and Twitter Spaces to engage with your followers in new ways.

How To Request A Refund For Your Apple Developer Program Fees

The Apple Developer Program allows individuals and businesses to create innovative apps for iOS, iPadOS, macOS, tvOS, and watchOS. Previously, users paid a fee to join, but after WWDC23, Apple made Beta versions free for all users with compatible devices.

So, whether you want a refund for your membership fees or believe the program isn’t right for you, this article provides a step-by-step guide to help you request a refund for Apple Developer Program fees.

What is the Apple Developer Program?

The Apple Developer Program is a toolkit that helps people worldwide create and improve apps for Apple devices. Even if you don’t know how to code, you can still be a valuable part of the program as a tester.

When you join the program, you get access to the newest software versions of Apple before their public release! As a tester, you can try those features and let Apple know if you find any problems. Your feedback is important because it helps Apple improve before the official stable release.

Besides, Apple holds a special annual event called the Worldwide Developer Conference (WWDC). Developers from all over the world are invited to join and contribute to developing new software. It’s an exciting opportunity to be a part of the latest creations from Apple.

What’s the annual fee for Apple Developer Program?

The Apple Developer Program currently offers two membership options. To join these programs, you need to pay an annual fee, which is as follows.

Apple Developer Program: $99

Apple Developer Enterprise Program: $299

However, there is also a way to access the Apple Developer Program without paying any fees. Apple generously provides free access to certain government entities, educational institutions, and NGOs. Additionally, Apple recently decided to waive the fees required for downloading beta software.

How to get a refund for your Apple Developer Program fees

Navigate to the Contact Us page.

You will now receive a Case ID, and a member of Apple Support will contact you within 2-3 business days to provide a final decision on your refund request.

When I spoke with Apple Support, I specifically mentioned requesting a refund for my Apple Developer Program membership.

I explained that I only needed it for beta testing operating systems, especially since it’s now free with Apple ID Sign-in. The support team escalated my case, and my refund was processed by the end of the day.

Tips for requesting a refund of Developer Account fees

Here are some tips I’d suggest if you plan to request a refund for your Apple Developer Account.

Be clear and briefly explain the reasons behind your refund request.

Express your politeness and respect towards the Apple Support representative.

Remember to include any pertinent documents, such as your receipt for the Apple Developer Program.

Ensure you request a refund within 90 days of purchasing your Apple Developer Account.

If you request a refund because you could not publish an app, include information about the app and why it was rejected.

Be patient and understanding. It may take some time for Apple to process your refund request.

How To Become A Cdo: Explore The Field Of Data Leadership

blog / Data Science and Analytics How to Become a CDO: Explore the Exciting Field of Data Leadership

Share link

Did you know? Over 319 billion emails were sent around the globe in 2023. And, Google processes over 8.5 billion searches a day. It’s no wonder British mathematician Clive Humby termed data the new ‘oil’. Nearly every company today relies on data for its decision-making. This demand for data and those who can understand it has resulted in the creation of job titles that didn’t exist until a few decades ago, like the Chief Data Officer (CDO). What does it entail, and how to become a CDO? Let’s find out!

What is a CDO?

ALSO READ:  Data Science vs Data Analytics: Key Differences & Opportunities

Where Do CDOs Come From?

The title of Chief Data Officer didn’t exist until a few years ago. Then, the handling of data and its security came under the purview of a chief information officer. The exponential rise in the volume of data and its value in business led to this title. According to Gartner, 63 per cent% of global chief data officers had prior experience in a data/analytics-related job. However, only 9 per cent% of CDOs come from an IT background. 

What Does a CDO Do?

A guide on how to become a CDO is incomplete without understanding the job description and responsibilities. Therefore, let’s look at everything a CDO does as part of their job role:

Overlooks the company’s data governance, security, and privacy

Facilitates innovation and digital transformation within the organization  

Creates cognizance of data security, governance, and privacy within the organization

Safeguards the company’s data assets

Works closely with and often reports to the chief information officer.  

Builds a robust data ecosystem and inspires a data-driven culture

How to Become a CDO Step 1: Get the Education You Need

Typically, a CDO should have a Ph.D. or a master’s degree in any data-related field, like data science or analytics, computer science, or statistics. However, along with a Ph.D. or Master’s, several experienced executives opt to undertake MBAs from elite universities or management programs to break into a C-suite role like that of a CDO. 

Step 2: Gain Necessary Experience

Most companies, including startups, expect individuals applying for CDO positions to have a minimum of 5-7 years of experience in the field. This can go up to 10-12 years of experience for larger companies. Given that it is a relatively new job title, the number of years may not matter as much as the depth and quality of your experience. Getting involved in and executing challenging projects adds significant value to your experience.

Step 3: Develop Leadership Skills

Chief data officers work with multiple teams across different channels, which requires them to possess exceptional leadership capabilities. One of the essential skills for any chief data officer is having excellent communication skills. As the common point across multi-functional teams, a CDO must communicate effectively with all invested parties. Additionally, C-suite executives must have empathy, critical and analytical thinking capabilities, and decision-making skills. These leadership skills can be developed over time with experience and acquired through learning.  

Step 4: Expand Your Influence

Networking is something all industry leaders and executives swear by, and rightfully so. Building the right connections can help you expand your knowledge and opportunities. Connecting with fellow industry experts and leaders is an excellent way to exchange ideas, learn about new changes in the market, and onboard expert individuals into your team. 

Step 5: Master People and Team Management Skills

A strong team goes a long way, especially when working in a complex and dynamic environment. A chief data officer will work with teams consisting of a diverse mix of people. Hence it’s imperative to learn the skill of managing large, diverse teams. Often, it’s easier to manage data than to manage people.

Step 6: Hone Your Data Analytics Skills

The foundation of a chief data officer’s role is deriving meaning from raw data. Therefore, as a CDO, you must have a deep and thorough understanding of data science and analytics. 

Step 7: Utilize the Connection Between Data Analytics and Business Performance

Any business that hires a CDO aims to improve its business performance. Processing chunks of raw data into a valuable output in decision-making is, broadly, the role of a chief data officer. This requires the CDO to have a deep understanding of the business, the threats & challenges it faces, and the targets set. Only then can a CDO successfully build a connection between his expertise and the business itself.  

What Teams Does a CDO Manage? What Makes a CDO Successful?

To succeed as a CDO takes more than just being good with data and analysis: 

Be data-focused to derive maximum meaning from raw data. 

Build a bridge between data, business processes, and decisions to create a seamless customer experience and make informed business decisions.

Be business-centric and analytically driven. 

Effectively communicate with relevant stakeholders.

At Emeritus, we understand what it takes to be a CDO. Beyond the information in books and the internet, it is about learning from industry leaders and their experiences. We work with the world’s leading universities to build programs that will provide you with the right resources to chart your path toward professional success.
