TRV 900 15P Conversion

When I was young and foolish or at least foolish, I shot some progressive scan video not realizing that it was only 15 fps. It is of course very jerky. I would like to improve on this video if possible by eliminating or at least reducing the flicker

When I examine the 15 fps frames it is clear that the TRV900 is sending out 2 identical frames to get to the standard 30 fps DV. If, for example, I could replace all the even numbered (duplicate) frames with interpolated frames then I should get a video with less flicker.

Question 1: Am I crazy to even consider this or there some processing around that would do the trick?

Question 2: If there is any processing out there, would it take a year to process a 10 minute video?

Just for kicks, with the project properties set at 29.97 try setting the Undersample Rate to 0.500 and Force resample. Theoretically this should skip every other frame of the source video and then force interpolation between them. It's worth a shot. However, any place with lots of action will probably end up looking blurry. You may have to split the video into sections to process the parts with little movement and leave the high movement scenes alone.

I tried the .5 undersample idea. Right clicked on the clip and set the undersample rate to .5. Set the switch to forced resample.

It sounds like a good idea but I can't see any improvement on a short clip with lots of motion. Comparing the original clip and the .5 clip I found that the net effect is that the .5 clip is offset by one frame from the original. It looks like Vegas isn't actually doing any frame to frame interpolation. It just duplicates frames to get back to the 30 fps.

Any chance I'm still doing something wrong?
