There can be multiple reasons why the video is lagging/glitching when you film a video.
Here is an example of one way the video can glitch:

This issue might be caused by one of the following:
Common Causes and Solutions
1. Video Processing Update
Did you recently create or edit a video and notice a brief moment where the video appears to update itself? Don’t worry, this is completely normal and not a result of any system errors. This simply indicates that the video has completed processing and is transitioning from being played on our frontend to being streamed from our servers. This occurs shortly after you’ve finished creating or editing your video on the edit page. Read more about this in our Video updates briefly once help article.
2. Device Restart
You have not restarted your device lately.
- Restart your computer to clear temporary files and refresh system resources
- This resolves memory leaks and background processes that can cause video glitches
- A fresh restart often fixes performance-related recording issues
3. System Updates
You do not have the latest system updates for your computer or browser.
- Update your operating system to the latest version
- Ensure your browser is updated to the most recent version
- Outdated software can cause compatibility issues with video recording
4. Resource Management
You are running too many programs simultaneously or have too many tabs open in the browser.
- Close unnecessary applications and browser tabs before recording
- This is influencing your computer’s performance, which sometimes can result in inconsistent recordings
- Prioritize MailVideo for system resources during recording sessions
5. CPU Performance
Check your computer’s Activity Monitor (MacOS) or Task Manager (Windows).
- Look for programs running in the background using unnecessary CPU performance
- End tasks that are consuming high CPU resources
- Identify and close resource-intensive applications before recording
6. Memory Management
Check your computer’s memory usage in Activity Monitor (MacOS) or Task Manager (Windows).
- If the computer is running low on RAM, it can influence the transcoding of MailVideo recordings
- Close memory-intensive applications
- Consider upgrading RAM if consistently experiencing memory issues
7. Hardware Drivers
Check you have the latest drivers for external microphones/cameras.
- Update video and audio device drivers
- Unplug and reconnect external devices
- Test with built-in camera to isolate hardware issues
8. Internet Connection
Check that your upload speed is at least 5 mbps to ensure smooth recordings.
- Test your connection at https://www.speedtest.net/
- Slow upload speeds can cause video processing issues
- Use a wired connection instead of Wi-Fi for better stability
9. Power Management
Record while your computer is plugged into a power source.
- Battery power can cause performance throttling
- Ensure adequate power supply during recording sessions
10. Power Saving Mode
Make sure your computer is not on power saving mode.
- Power saving mode reduces CPU performance
- Switch to high-performance mode when recording
- This ensures maximum system resources for video processing
Prevention Tips
- System Maintenance: Regularly restart your device and keep software updated
- Resource Planning: Close unnecessary applications before recording
- Hardware Check: Ensure all drivers are current and devices are properly connected
- Network Stability: Use a reliable internet connection with sufficient bandwidth
- Power Management: Record with adequate power supply and performance settings
