I've been trying to transcode an MTS (recorded on a Panasonic) to MP4 with Adobe Media Encoder. The audio/video has consistently gone out of sync. I've matched the source, gone over all the settings, and restarted both computer and program, but it hasn't seemed to work.
I then turned to other encoders with different results. Out of all of the ones I tried, Wondershare Free Video Converter seemed to work the best: it didn't desync the audio/video, and it didn't interpolate the video. Using MediaInfo, I tried to recreate all the parameters from Wondershare to Encoder, but the audio/video STILL go out of sync.
I just don't know what I'm doing wrong. Below are the specs of the MTS (original), Wonder Share (no sync issues), and Encoder (-500ms audio/video desync).
