Blending 500FPS down to 30FPS

[netrex]

I want to blend the 500FPS my source has down to 30FPS to create a motion blur effect.

I tried playing around with MVTools trying to created motion blur of a 30FPS source, but it didn't look very good compared to what blending does. I can do it in After Effects, but I want to do it straight after the footage export.

Is there a way to do it with AviSynth? I've tried using MVTools and MVFlowFps2, but it only converted it to 30FPS, no blending of the frames. I guess it can only create frames when it's going up in framerates or I did it wrong (very possible).

The most basic way would be : video30fps = video500fps.temporalsoften(5, 255, 255, 10, 2).changefps(30)You can play with the strength of the blending by changing the first '5'.

Wow, that did it =) I'll try different values and see how it turns out and put up so you can check it =)

It's footage from games I use, and all frames are perfectly clear, so it doesn't really do encoding any good, will save plenty of space with this =) And hopefully it will encode faster than when AE renders it.

Thanks a lot :D

Ok, here're some screenshots of some frames with 0, 5 and 10 as the first value.

I'm encoding some test footage in 768x423 as well as 720p, the 768x432 is resized down from the 720p source. The image quality on the 1280x720 screenshots will be higher for the real deal, cause I'll export at 2048x1152 and resize down to 720p. Also testing 30FPS vs. 60FPS to see how it looks and how the filesizes will be. 60FPS feels much smoother usually, but not sure how it will feel with motion blur on as well, if it's worth the extra time and space. Though with no blur, 60FPS clips only take about 30% more space in my experience.
