I've been converting MTS to H.264 files for a job recently for archiving and storage space.
Creating an H.264 and cropping the footage greatly reduces the space taken up by all the MTS footage.
However, I've noticed that after export, the H.264 files are a few frames off in terms of sync. I crop from the beginning and end, where there is "garbage". I have the settings to Match Source with Adaptive Low Bitrate.
Where am I erring and how (if any way possible) can I transcode these MTS files without the audio/video going out of sync?
Adobe Media Encoder 2019
