Rrendering H.265 (nvdia HEVC) video with the extension mp4 or avi, the video does not play.

Are you using Voukoder, or VoukoderPro? Which version?

using Voukoder 13.1

And there's your problem. Use version 13.0 instead.

See this forum: Output file is not playable on Windows

It sounds like you're facing a codec compatibility issue with Windows 10 and the Adobe suite. When rendering H.265 with NVIDIA HEVC, some compatibility hiccups can occur, especially with MP4 or AVI formats. It's not uncommon; I've seen similar issues in various forums. MKV format generally has better support for H.265, which is likely why you're not facing issues there.

For handling MP4 formats I've been using Movavi. Pretty easy to use and reliable option. See more about it and other alternatives in this article: https://www.movavi.com/imovie-for-windows/.

Nope. Voukoder 13.1 had a bug causing the playback issues. Fixed in Voukoder 13.3.

This was detailed in the forum I linked above.
