i recorded 2 of about 25 tapes in F5 instead of F6-- so of course i have to do reverse telecine on the captured clips from the 2 tapes....this i did ( a batch reverse...) and it worked really well....but not all the clips got done ( some were skipped for some reason...) .. so i went back and did the lagging ones individually ,,,and heres where it gets weird...about half reversed just fine...but the rest simply wont switch....i go thru the whole process and after it finishes the clip just sits there still in 29.97..........i dont know what i could have done diff. to these clips to make them so balky.....also, i tried using the "conform to 23.98" button on a few of them...the frame rate DID seem to change...but then the sound dropped everyones voices an octave or more!!! HELP ....
