Rewrap MP4 to MOV files

[SCDVD]

I have some XDCAM EX MP4 files that I need to rewrap to MOV files for someone who will edit them with Final Cut Pro on a Mac. I don't want to reencode because it will damage the video to do so. I am looking for a good rewraping utility. MPEG StreamClip doesn't recognize the XDCAM EX MP4 files

ffmpeg can do it ; it's a command line utility

ffmpeg -i input.mp4 -vcodec copy -acodec copy output.mov

Thanks, this looks like what I need. I haven't used ffmpeg before. I downloaded it but I don't know how to use it. Can you recommend a good tutorial or documentation for it?

You have to use a command prompt.

Here is what I was told to do...

Put a copy of ffmpeg.exe in your home folder (C:\Documents and Settings\your name).

Put a copy of the file you want to convert in the home folder.

(I also put a shortcut to command prompt so I can run it from that folder).

Open command prompt and type...

ffmpeg -i input.mp4 -vcodec copy -acodec copy output.mov

and press enter



If you want to convert a bunch of mp4 files to mov then you can make a batch file. Open note pad and type...

for %%a in ("*.mp4") do ffmpeg -i %%a -vcodec copy -acodec copy %%~na.mov

...save as mp42mov.bat in the folder where the mp4 files are at and double click the bat file.

When I run it, I get a message (See attached) and the converted file doesn't play. Any suggestions?

It doesn't play in what? mpeg2 in mov usually won't play on windows software, except mplayer and it's derivatives (e.g. smplayer)

also r18639 is quite old, maybe try a newer build , it might be a muxing issue

you can use auto compiled builds here

Is this 1080i60 ? ffmpeg sometimes has issues with interlaced content

Thanks poisindeathray! You are a complete genius. I downloaded a recent version of ffmpeg and it ran fine. It plays OK in SMPlayer. Thank you!

Thanks for the tip DarrellS. After poisondeathray straightened me out, it works like a charm!

I'm just learning to use ffmpeg myself. The guys around here and the Virtualdub forum have been helping me out. I found the instructions of using the home folder using google.
