Hello! Im having problems muxing a video with audio and chapters for iTunes and iDevices.
So I went to tools/muxer/mp4
Then choose h.264 video, .aac audio, and .txt chapters, choose right fps and the iPhone preset
Then I mux.. The output is a .m4v file with video, audio and chapters, but the file is longer for a minute or so, I dont know why.. Anybody knows how to fix this?
