3ivx Batch Conversion Available? Possible Script?

[fitch.j]

I'm looking to convert a (large) collection of 3ivx video files recorded on Flip Mino camera's. Ideally into MPEG2 format, or some other form of light compression.

The reason behind it is these cameras are used by some of the students in my school, a lot of whom wish to edit on Premire Elements 1.0. However the 3ivx MP4 files are unsuported.

I've been able to convert these files individually. I'm just wondering if there is a script that i could write, or that is around, put in the same directory and run, for it to convert them all. I'm fairly bad with scripts but have used them in this way before for converting some AVCHD footage.

To give you guys more info, here is what MediaInfo says about the source files:

THat looks like avi xvids...

But anyway you could use ffmpeg and convert to mpeg2, make a .bat file with

for %%a in ("*.avi") do ffmpeg -i %%a -acodec mp2 -ab 128 -vcodec mpeg2video -o %%a-new.mpg

(you probably want some more settings like video bitrate etc...see http://www.ffmpeg.org/ffmpeg-doc.html )

and run it in the same folder as ffmpeg and the avi files.

Thank you so much for this. I've experimented with it a little and managed to make it a standalone converter assuming ffmpeg is in the correct location making it easier for the students. I'm going to change the location from C: to a public network drive.

I had a few issues with the sound in the script you suggested but managed to sort it out. Just for reference for anyone else who may be interested this is the final script i have come up with:

for %%a in ("*.avi") do c:\ffmpeg\ffmpeg -i %%a -acodec mp2 -ab 192k -ac 1 -vcodec mpeg2video -b 5000k %%a-new.mpg

Thanks again Baldrick
