Bandicam HVEC encoding causes issues in multiple applications

Sat Jun 12, 2021 5:46 pm

Im having issues with HVEC (Intel Quick Sync) MP4 files created by Bandicam. In VLC, the video plays with problems like black spans and cuts and freezes. In Magix Movie Editor Pro video editor, the software complains about missing QuickTime, and when it's installed it complains about a missing MXMPEG2 codec. [ok so Magix MVP is just confused about the encoding]. In some other players like Windows Media Player the file works fine with no issues.

In ffmpeg, I see some issues reported; here's the output for a sample file:

--------------
>ffmpeg -i file

[hevc @ 000002b76d49fec0] SPS 0 does not exist.
[hevc @ 000002b76d49fec0] VPS 0 does not exist
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'intro-tab.mp4':

If I run the file through an ffmpeg conversion
[h265->h265, eg ffmpeg -i input.mp4 -c libx265 -crf 12 output.mp4],
then all the above problems in the different programs disappear, and I get the following report on the converted file:

-------------

It seems like a Bandicam encoder issue, but happy to hear your thoughts on this.
