Iíve been testing the video conversion function of every new version of Avidemux for many years, and it has NEVER completed without something going wrong. It crashes (itís amazingly unstable for an app thatís been around for so long), or it only converts part of the video, or on the rare occasion that it completes an encode it creates horrible looking video ó it simply ALWAYS fails in some way. Itís got a lovely feature set, and Iím sure that some of its capabilities work, but since every new version fails to do a simple conversion (like .avi to H264), I always end up chucking it in the trash. And I know itís not my fault because Iím quite adept with every other multimedia utility I use (Iím even pretty good with ffmpeg via the command line).

This time it failed by only completing around 20% of an AVC to HEVC conversion with audio passthru ó without giving any indication that it failed to complete the other 80%. Both iFFmpeg (commercial, but very cheap) and Handbrake (free) converted the same video file with aplomb.

Running macOS 10.12.5 on a 2.8 GHz Core i7 MacBook Pro.
