Step 1: Check the file inside Movavi

Add the converted file back into Movavi Video Converter.

• If the file opens and plays correctly, the conversion was successful.
• If the file does not open, continue to Step 4.

Step 2: Test playback in another media player

If the file plays correctly inside Movavi but not in your default media player, this indicates a playback compatibility issue.
Try opening the file in a media player with built-in decoding support, such as VLC media player.

If the file plays correctly there, you're all set.

Step 3: Playback support for default system players (advanced)

Some default system media players rely on system-level decoding components.
If you need the file to play in such players, installing additional playback support may help.

One example of a commonly used codec package.

⚠️ Installing codec packs modifies system media components.
If you are unsure, using a media player with built-in decoding (such as VLC) is generally safer.

If the file does not open even inside Movavi:

• Convert the original file again.
• Select a different output format.
• Use a widely supported format such as MP4 (H.264).

For older versions of Movavi Video Converter, if playback fails with one format, test another format to verify compatibility.
