Progressive Slow Motion Settings

[amendegw]

First, my disclaimer - I have little clue what I'm doing. I'm trying to use MVTools2 to slow some 1920x1080 59.94 fps progressive footage from a Panasonic TM700 to 1/4 speed.

I'm frameserving out of Sony Vegas to the following Avisynth script:
loadplugin("C:\Program Files (x86)\AviSynth 2.5\plugins\mvtools2\mvtools2.dll")

AVISource("C:\Users\Jerry\Documents\Vegas Projects\@DebugMode\SloMoTesting.avi").Killaudio()

super = MSuper(pel=2)

backward_vec = MAnalyse(super, overlap=4, isb = true, search=3)
forward_vec = MAnalyse(super, overlap=4, isb = false, search=3)


MFlowFps(super, backward_vec, forward_vec, num=4*FramerateNumerator(last),den=FramerateDenominator(last))

assumefps(59.94,true)

I can't seem to get a smooth Slow Motion output. Here's what I see (re-rendered to h.264, but I've retained the 59.94 framerate): http://www.jazzythedog.com/testing/SloMoEagle.html

Can someone show me the error in my ways?

Looks like frame repeats , did you check your source file to see if it's ok (the export from vegas, go frame by frame in vdub and check for repeats) . If there are problems with that, go back to vegas and check the settings there

(You don't need "true" for assumefps, since you aren't using audio)

Poison, That's it! It was a "dumb operator error" on my part. Turns out I had plopped one of my previous failed attempts on the Vegas Timeline and that was the source of the Frameserve render.

Thanks so much for your help. A little later today I'll post the fixed slomo - this time to 16x (in case anyone else is interested).

Thanks again!

Okay, here's the fixed footage. The motion is fixed, but now I see some nastiness at the Eagle's wing tips. Is there any way to fix that short of shooting at a higher shutter speed? (it's in the VirtualDub Lagarith output - as well as the final web render).
