Virtualdub/Mpeg/Mod

[johnlm]

I am trying to use VirtualdubMod (or Mpeg) to clean up an Mpeg of some old cine films. Some bits are quite dark, other parts are light. Can I apply different levels of filtering to different parts of the file, or do I hae to split them, filter and then rejoin. (I'm sure there must be an easier way
Thanks for any help

I'm afraid that's basically the procedure. At least, that's how I'd do it.

Remember vdub only save's as avi , not mpeg .

So in any case , you will be needing to split it into piece's as you go with the filter applied according to your need's , compress with chosen codec , and audio as well .

Use append method to rejoin clip's .

Frameserve too bbmpeg (accept's both .avi and .avs , handle's audio) or quenc (.avs) to reconvert to mpeg .

All right, but bbmpeg is quite ancient and can't keep up with newer ones. You may want to use free stuff like quenc, in this case toolame is good for audio, or you may want to get something like CCE Basic if this isn't a one time job.
Frameserving is not difficult but in case you may find some hints on my page.

Cheers

Using the Trim or ApplyRange commands, you can accomplish this easily by frameserving using AviSynth. No need to break it into pieces.

There's a filter for VDub called 'Conditional' that allows you apply a different filter to a range of frames. By using additional instances of 'Conditional' you can apply different levels to different sections.

It can do MPEG direct via YMPEG ($30 ) and *I think* someone once said that ffdshow can facilitate it also ...
