Motionfilter

[anton_foy]

Hello!

First of all I must tell all who reads this that I am both a noob and I can't write plug-ins either:S

The point with this thread is that I had an idea of a motion-adaptive-morph-filter, for the use of making (~100~500 fps)slow-motion.
Some of you may remember or even used a morph-program. A plug-in with motion adaption on the images and morph the adapted areas between them, would that be a good idea?

Just a thought, It would be interesting to hear any comments on this :)

[EDIT] Oh I just saw the Motion compensation, temporal upsampling thread pop up. Looks like someone already looked in to this morph-idea, I should not have been so eagered posting this;).

I use mvtools then my camcoder nigth mode - nearly morph (Excuse me, My very bad English)
(for mvtools see http://bag.hotmail.ru)

Hmmm...I don't really understand your sentence, sorry but you use Nightshot mode on your camcorder to get a better slowmotion?

What I meant was using a morphing between frames to get new frames. So by morphing between lets say frame 1 and 2 you tell the function to add a new frame between them making it 2x the current fps (before: 50fps, after: 100fps).

i think what he means is that he uses mvtools (block-based motion estimation with mesh-based motion compensation. rather like photoshop's "liquify") to get a higher framerate out of his DV cam in nightshot mode (which is usually very choppy, like 12.5fps).

@MugFunky and AI
Ahaa, I see. Making 12,5 fps in nightshot mode to 25 fps then? I saw a great clip a while a go here. It was someone Yo-Yo'ing and it was slowed down 1x, 2x, 4x and 8x. I think it looked very good IMO but I can't remember what filter was used. Someone ever tried it on 50i HD? Would be interesting to see how it turns out :)

sory, I have sacking from my work, and have not I-net

SelectEvery(14,1) #camcoder in night shot 1 frame every 14 frames in DV-tape
ConvertToYV12(false)
# hereinafter RTFM
backward_vec = MVAnalyse(isb = true, truemotion=true, pel=2, idx=1)
forward_vec = MVAnalyse(isb = false, truemotion=true, pel=2, idx=1)
cropped = crop(4,4,-4,-4)
backward_vec2 = cropped.MVAnalyse(isb = true, truemotion=true, pel=2, idx=2)
forward_vec2 = cropped.MVAnalyse(isb = false, truemotion=true, pel=2, idx=2)
Last.MVFlowFps2(backward_vec,forward_vec,backward_vec2,forward_vec2,num=25,idx=1,idx2=2)

I have "motion-adaptive-morph-filter" between every 14 fames
