converting a choppy file from 18fps to 24fps

[Akuma786]

I overlooked yesterday that there are 3 Resample methods in Vegas Pro. The file originally uploaded here had Resample disabled. The other 2 methods are "Frame Blend" and "Optical Flow". All 3 are now at post #24 and also in the zip file.

I think the Resample - Disabled, probably looks the best.

Issue is the missing frames in the fast action fight scenes which make the video look too fast. Without them frames doesn't seem right. Would be nice to Interpolate them frames some how!

One of the main reasons I purchased Topaz was because I had quite a lot of Canon iXus v3 15fps clips. I used Topaz to convert to 30fps and very happy with the result.

This action footage was always going to be difficult. I think if you weren't limited to finishing at 24fps it would allow more flexibility.

For fun I have attached a telecined version, 18fps to 30fps NTSC and a Topaz interpolated version, 18fps to 60fps. Input and output duration 30 seconds. Do they look a little better, more acceptable ? They are also added to the zip file.

It has the least distortions. But that's because all it does is duplicate frames.

As was noted before, you have to analyze the motion between frames visually, detect where frames are missing, and how many frames are missing at each of those locations, then use a motion interpolator to insert new frames. This is easiest if you have a reference with no missing frames.

As you've seen with some of the simple samples, interpolation doesn't work well with large complex motions. Some things get distorted, some things disappear, some get ghosted... You can try using ReplaceFramesMC() -- which can be found in these forums. Or ReplaceFramesRIFE() which interpolates better (but has a bug where it runs out of memory after a number of calls).

Hmm, I guess maybe it's best that I just work on it at 18fps, the fps it was screen captured at, and maybe it be easier to keep the original runtime and not speeded up instead.

I shall try to install avisynth tonight and give this a try and see how it looks. Thanks

I thought that the 60fps clip looked passable, compared to the others.

The topaz 60fps file is shorter compared to the original clip time. I want to keep original runtime.

Fair enough, i'm not sure why ? The shorter 30 seconds clip is shorter because the duplicates are removed. Of course there will be plenty added back in with the 60fps interpolated clip.

Check out the same scene from older print available and you notice that the clip i have is faster in comparison and only gets faster once duplicates are removed.
