1080i video -> h264 mp4 encoding error

[lfebaggins]

I have been successful so far converting .m2ts videos to 1080p mp4 until recently I came across a .m2ts video that was 1080i source.

I tried running a deinterlace filter while encoding it into a mpeg-4 avc/h264 mp4 video in different video editing programs such as AVS Video Editor & Magix Movie Edit Pro, and the results have been either a finish but corrupted video file that cannot be played in any media player or a finished working video file but the video/audio is out of sync. I then try something unconventional and encode it into a 1080p avi file, and it is successful. Video plays fine except for your typical lag here and there from trying to put h264 codec into an avi container. I then try to reencode the produced video into a mp4 and it still ends up as a corrupted video file.

Is there a step that I am missing because this time its a 1080i source?

Hi

How do you demux your video from the .m2ts container ? Are you sure it is really interlaced, and not just flagged as interlaced ? There are things you can do to visually check if video is interlaced or not, I'de be happy to tell you what I do.
