What Is a Good Screen Recorder?

There are two important points to consider when looking for the best free screen recorder in 2021.

1. File Format & Compression

A file format is a particular way of organizing the data within the file. There are many video file formats and some screen recording tools support more than one. However, most of the time, it goes down to MP4 vs. WMV.

MP4 or WMV for screen capture?

The WMV format is a product of Microsoft. Back in the day, it was created to allow professional videos to be recorded in high quality, e.g. on DVD, Bluray. The biggest issue here is that Mac users often have trouble viewing WMV files.

MP4, on the other hand, helps you produce video files that can be opened on any platform. And, when it comes to video quality, MP4 is actually better than WMV.

So,MP4 is more suitable for publishing your screen captures on the web and sharing them with others. The best free video capture software allows you to save your videos in MP4.

2. Video Hosting & Uploading

When looking for a screen capture software, you’d probably look at the recording features like — recording time, ability to record the computer audio, and so on.

But what happens after you record your screencast?

Most of the time, video files are very big and can’t be attached to emails. This means that, to share a video, you have to upload it somewhere in the cloud. In other words, you need video hosting.

This is a book-worthy topic but here are a few things to keep in mind:

• Hosting on YouTube. Some screen recorders allow you to post your videos on YouTube. That’s great when you want to share your videos publicly but not recommended if the screencast contains sensitive information.
• Proprietary video hosting. Some screen recorders like Screenrec, Apowersoft Free Online Screen Recorder and Screencast-O-Matic come with video hosting. When storing your videos on these platforms, it would be wise to research if the platform is free and what level of security it offers.
• Cloud Recording. If there is no Cloud Recording option, you will have to wait for the video to upload until you can share it. The best free screen capture tools come with this option.

Conclusion

Even the best free screen recording software has advantages and disadvantages. At the end of the day, the recording features — what you can do with the tool, are just as important as the effectiveness — how quickly you can record your computer screen and share it with others.

So, before you set your mind on a free screen recording software, it’s best to evaluate your own recording needs. Maybe you don’t need to upload your videos to social media or maybe you don’t need to record in HD.

Based on this criteria, the top screen recording software for us is the free screen recorder by ScreenRec. The final decision is, of course, yours to make.

As the names suggest, the biggest difference is that a desktop screen recorder can capture your screen while you're offline or on a poor internet connection. An online screen recorder requires stable Internet. For this reason, an online screen recorder isn't the best option when it comes to game capture. It may be a viable option when you're recording a tutorial, though.

Screencast-O-Matic is a popular screencasting tool. Many people use it to record tutorials, training videos and other educational content. The biggest advantage of Screencast-O-Matic is, perhaps, the ability to share the recording to a number of platforms like Vimeo, YouTube and Screencast-o-Matic's own video hosting platform. One downside, however, is the fact that you have to wait for the recording to upload and, if you've been recording for, say, 1 hour, this can be a huge pain. That's why, as an alternative, we'll suggest ScreenRec. It's quick and lightweight, allows you to capture both your computer audio and microphone audio and, finally, it's got instant private sharing--your screen recordings are uploaded in real time which means that you never have to wait. You get a sharing link as soon as you press 'Stop'.

It depends on the screen capture tool you're using and your platform (Windows, Mac, Linux, etc). With ScreenRec, for example, you have to press Alt + S to start recording your desktop. This works on all platforms.
