Most modern screen recorders default to MP4 or MKV (which can be remuxed to MP4 in seconds). Method 3: Converting AVI to MP4 (Post-Export Cleanup)

Launch the official application on your computer.

Click the menu icon (three horizontal lines) in the top-right corner and select Recordings .

Put the AnyDesk player into full-screen mode to remove UI clutter.

Install the free software from the official site.

Note: If you are using an older version of AnyDesk, this built-in renderer might output an .avi file instead of an MP4. If this happens, follow the conversion steps in Method 3.
