will be fixed in the next version (very soon!)
Alright, updated to 4.2.0.136 and now the transcoding goes through without errors. But the audio doesn't work perfectly. The output video file plays the sound only every now and then, maybe about once per 10 seconds. And only 1 second a time. Rest of the time the video is silent.
Suggestions? I can shoot a longer example video if you need.
EDIT: 4.2.0.137 in, now it works, thanks!
