Hey guys. I'm a novice vdub user, really dig processing with vdub, it's been a few years. Anyway, going through some archive stuff I'm normalizing and cleaning up sound on, and I've got a bunch of stuff that's in Div3/MP43. On Win7ult now and there are no issues in playing these vids. But wondered, while I process the audio I want to, what if I also re-encoded these Div3/MP43 files to something more up to date? Came across the 0x0161 issue already and could not get a filter to work in Win7ult x64, as a work around I'm demuxing on an XP box. But while doing this, it got me thinking. I posted once and got a reply that if you wanted to re-encode an already encoded compressed .avi file (not that you'd look to, but if you did), that fast-repack would be the mode you'd want to use. In doing this, if one did, and if I considered it to get out of Div3, would I gain anything to decode the Div3 to RGB, then, encode RGB to say the latest xvid or something current in Divx? -thanks, jbbr

As long as you aren't applying any filters yes.
"In doing this, if one did, and if I considered it to get out of Div3, would I gain anything to decode the Div3 to RGB, then, encode RGB to say the latest xvid or something current in Divx?"
Presumably you'd get somewhat smaller file sizes, exactly how much I couldn't say but unless you have a specific need for decreasing the filesizes more it's probably not worth the time and probable quality degradation from another recompress. |

Yeah, I thought the same. Thanks for the reply |
