Topic: Transcoding with Quick Sync is broken | software encoding still works

I want inform you that transcoding and compressing with QSV doesnt work anymore. Transcoding with sofware compression still works as it should.

Transcoding to h.264 and h.265 stops with an error.
Transcoding to AV1 is working at the first look but produces bad files e.g. interpolation to 120 fps give a file with 105 fps with short "bursts" to 120fps every second.

Tested on two different PCs

what error? show the transcoding log.

Re: Transcoding with Quick Sync is broken | software encoding still works

just found out it depends what container the source is.
transcoding of a testvideo in mp4 container works but when this video is put in a mkv container via MKVToolNixGUI it fails.

this is more like a source video problem - some frames timestamps are not correct, probably
