I’m transcoding some of my old mpeg4 videos (in avi containers) to h.264 with FFmpeg.

Is there a tool out there to convert the video to a format by just replacing the container format? That’d be a … Read more
I have two halves of a single show in two .MP4 files, encoded in H264. I would like to join them without re-encoding. Is this possible? I managed to create a joined video as a Quicktime file (.mov) using Quicktime Pro, but then Quicktime Pro will not convert it back to .MP4 without re-encoding. This … Read more
