Does anyone know how I can resize a divx AVI file without re-encoding it too?? I was using virtual dub's resize filter, but it only lets me add a filter if I do full processing and i have to choose a compression codec otherwise it'll do "uncompressed" which wouldn't be good.

any clues??

the reason i want this, is when i convert DV to divx 4.11 using adobe premiere, i have to de-interlace it, but you can't de-interlace it after its been resized (it comes out like crap), so i have to resize it after converting and deinterlacing it.

unless.....hmmmm

what if i deinterlace it back to DV....oh blah i dont know what to do about this, but 720x480 divx movies are just too big...if i can reduce the size to say 512x388 i'd be a happy camper

Hi, I capture from DV. Here is what I do, maybe it will help you? (hope so!)

right, use AVI_IO to capture 25fps or 30 fps. It will split the files over a few files. set each file to about 3714MB.
Audio = PCM CD quality.
YU12, no recompression 320*240

Start capturing. Then convert to MPEG2 using TMPGENC. Once completed, convert to DIVX using VIDOMI or MPEG2 to DIVX encoder using DIVX 3.11alpha fast 75crisp (any k/frame u want) and MP3 128kb/s 44100Hz or WMA (your choice). Then encode it to DIVX 3.11alpha. it works well with fast motion from DV, no blocks (may be the odd one)

This then should work, cause it always does for me. DIVX 4.11 or 4.xx is crap. GOOD picture quality but file size is rediculous + slow encoding.

Thanks

Thanks for the info.

You know, i had stayed away from divx 3.11 because i could never figure out how to get decent quality encodes...but now i think the problem wasn't the codec, but my computer wasn't performing well enough to play them back properly.

i might try the 3.11 codecs just to see the difference.
