Format/Codec for Readability and Editing

dust · Post by **dust** » Fri Apr 06, 2007 10:38 am

I'm trying to decide which format/codec to use to convert my camcorder (.MOD) to a something easily readable but still high quality for editing later. Any ideas?

And no, I can’t just rename the .mod files since the widescreen video is squished until converted.

Thanks in advance!

well, you probably want it as a lagarith AVI. i've never dealt with.MOD before, so i couldn't tell you howto convert it

what do you mean squished? just rename to mpeg2 and fix the resolution with avisynth.

The video is squished horizontally, probalby due to having a WS camcorder.

This is not really a how-to question but a what format/codec should I use kind of question.

Can you just 'fix the resolution' in avisynth w/o encoding?

If space isn't a concern, then convert to Huffyuv or Lagarith.

Personally, I'd just archive the original MODs. Then if I needed to edit them later, I'd convert the videos at that time.

If I need to adjust the aspect ratio flags of an MPEG video without re-encoding, I use ReStream. Unfortunately, it works only on elementary video MPEG streams (M2V, MPV), so you'll have to demux the file first. After adjusting the aspect ratio flags, you'll need to re-mux the video and audio back together and I'm not sure that you'll be able to combine MPEG2 video and AC3 audio into a MPG container easily. VOB might be easier.

Since these MOD files are non-standard MPG files containing AC3 audio (instead of MP2), they should be very similar to VOB files from a DVD. What happens if you rename the file extension to VOB?

Nothing changes, it still opens in MPC and is squished. It is the same as renaming with .avi or .mpg.

i was thinking that after you rename them you could just use the avisource(), mpeg2source() or whatever and then just use lanczosResize command to fix it with the resolution you want
