Greetings everyone!

I’m currently working on some custom edits of a few movies and have run into a few snags, and was hoping to get some tips.

I’m working on a semi-fan edit of Dumb and Dumber; I didn’t care much for the unrated edition and stupidly got rid of my original DVD upon buying said new version, luckily I was able to find a torrent of the theatrical version 😃

Now, here’s my plan; I found some clips on youtube of some short scenes not available on most releases;

Lloyd returning with change to find the little old lady has vanished and stole his wallet and beer (only available on Australian R4 DVD)
Lloyd almost getting hit buy a car while walking into the convenience store (apparently aired on TBS, but never remember seeing it. Replaces scene of Lloyd leaving store swinging restroom key around)

I’d like to try and add these scenes into the original cut to create a quasi special edition. I have all the ‘pieces’ of the movie in place thanks to VirtualDub, but unfortunately the frame rates don’t match up when trying to combine them, and changing the fps rates causes sync errors with the audio. Any advice?
