This is my second thread for a silent film, I apologize. Thought it would be less confusing to do a separate thread for a separate clip.
So here's the clip:
http://www.mediafire.com/file/aqglgo7qd9xa0hp/epicsilent.avi/file
What is the proper way to make it progressive but at the correct speed?
I started a similar thread about a year ago and manono gave me a script that worked great!
Thanks!

This is my second thread for a silent film, I apologize. Actually, this is your fifth post asking for help making film captures progressive and playing at the correct speed, but that's OK.
I am not at my office, so I don't have the tools I need to analyze this, but the clip clearly contains field blends and you will need to use SRestore.
Most likely final playback speed will be quite slow, probably around 12 fps.
On my laptop, I was able to bob the clip using a trick in Vegas. I then counted how many fields it took to get 20 frames. I counted 54 fields. That's 27 frames.
(20/27) * 30 fps = 22.2 fps.
If my counting is correct, that is the number you should feed to SRestore.
When using SRestore you want to set the fps to give you a clean result, but without paying any attention to the resulting speed. Once you have a result without any residual dups, without any skips (from deleting too many fields), and without any remaining dups or blended fields, you then set the playback speed using AssumeFPS() as the last statement in your script.
I can't test this, but to get you started, something along these lines might work:
bob(source,-0.2,0.6)
output=srestore(frate=22.2, omode=6)
assumefps(12)

TFM()
TDecimate(Cycle=37,CycleR=10)
There's a frame missing after frame 110. I checked further and it's missing in the source also. Other than that, the script seems to work well.
