Need help with brightness

[perdomot]

I'm using VDub to capture my old vhs movies and TMPEG to convet to vcd and I've noticed that some tapes are too bright or too dark. I know how to use the Vdub filter AFTER I capture the AVI but then I have to wait for it to save the new AVI after I alter the brightness and the new file also takes up a ton of space. I tried setting the filter before capturing but it didn't work. Is there a way to capture and alter the brightness at the same time or maybe during the encoding process with TMPEG? Thanks.

Thanks for the help! This will be a big help with those older films.
