I have a video recorded with an iPad, and I want to rotate it.
I tried the solution provided in this answer, but first I get this warning :
If the file is using B-frames as reference, this can lead to a crash or stuttering. Avidemux can use another mode which is safe but YOU WILL LOSE FRAME ACCURACY. Do you want to use that mode?
I tried with both No and Yes to that question above, and with MPEG-4 AVC for the video output, and "AVI" as the format. However the resulting video's audio is messed up, even though I just used "Copy" for the audio stream.
The audio becomes very choppy, inintelligible.
What settings should I use then ?
Info about the source video :
- Container : Quicktime
- Video codec : H.264
- Audio codec : MPEG-4 AAC
