Lossless transcoding of AVCHD to mp4.

[yardline]

So since AVCHD is just h.264 video with AAC Audio, if would seem like you could just transcode it losslessly to an mp4 wrapper that iMovie could natively recognize. Am I wrong about that, or is there a tool to do such a thing?

I struggled to find the answer to this. In the end I found this:

Given your source audio is just AAC and not AC3 it should work seamlessly using a copy of each.

Goodluck.
