I'm using Vdub to adjust the FPS manually in an AVI before conversion with TMPGenc. This fixes a gradual sync problem I have. My question is- Is there a faster way to do it? Trial and error with this method is taking hours. Adjust the FPS, Save the AVI, Convert a small clip, Test the clip etc. Saving the AVI (direct stream copy, no audio) takes up to 6 min. Should I be saving just a clip from Vdub? I tried the setting "change so A/V durations match" but it didn't work in this case. Any suggestions of a speedier way would be appreciated!

p.s. If this is a repost it is by accident. Merry Christmas!
