I do video editing in Lightworks on kxStudio 18.04. Since Lightworks doesn’t really have audio features, I usually do stem export there, and then I do film mixing in Ardour. Luckily, I can add the video to my Ardour project.
However, the extracted audio from the video file as well as the video itself and the audio stem files are not in sync. When I open the stem files and the video file in Audacity (which will extract the audio from the video), they are perfectly in sync. After importing stems and video into Ardour, they are not. The stem tracks are too early.
Is this a bug, is there something I don’t understand?
Since quite some NLEs allow to move audio only in the unit of video frames, re-aligning stuff is always uncomfortable. It would be great to simply have stuff properly aligned right away.
Hints are welcome.
