Create interpolated frames

[Bluedraft]

Hi,

I just removed these 4 bad frames from a clip

DeleteFrame(110192, 110196, 110199, 110200)

Now I would need to fill those spaces with 4 interpolated frames in order to keep the clip smoothly in that portion, any idea how to do this?

Thanks in advance for any help.

Well firstly, you have now created a new clip and would have to recalc the bad [EDIT: Interpolate] frame numbers, or put back dummy frames into the original bad frame positions.

There are many scripts for doing as you wish (see the related thread a few threads after this one at time of posting, and containing links to other threads on same subject),

However, this is what I would choose.

First off, use original clip (pre-deletions).

FrameSurgeon:- https://forum.doom9.org/showthread.php?t=173158

Something like this

Avisource("...")

SCMD="""
I 110192
I 110196
I 110199
I 110200
"""

FrameSurgeon(scmd=SCMD,Final=True)


EDIT: Of course above script uses MvTools Interpolation not blends, dont know what Mounir is suggesting below.
Also, above will cope with thousands of frame replacments (no known upper limit, but limited to max 9 frames interpolated per replacement), whereas script in below post will likely screw up if more than about 70 or so replacements (although not limited by replacement length).

if you want to create real frames not just blends use this:


LoadPlugin("C:\Program Files (x86)\AviSynth 2.6\plugins\svpflow-1.0.6\svpflow1.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.6\plugins\svpflow-1.0.6\svpflow2.dll")
avisource()
ReplaceFramesSVPFlow(110192,1) # replace frame 110192, duration 1 frame
ReplaceFramesSVPFlow(110196,1) # replace frame 110196, duration 1 frame
## etc....

Function ReplaceFramesSVPFlow(clip Source, int N, int X)
{
# N is number of the 1st frame in Source that needs replacing.
# X is total number of frames to replace
#e.g. ReplaceFramesSVPFLow(101, 5) would replace 101,102,103,104,105 , by using 100 and 106 as reference points for SVPFlow interpolation

start=Source.trim(N-1,-1) #one good frame before, used for interpolation reference point
end=Source.trim(N+X,-1) #one good frame after, used for interpolation reference point

start+end
AssumeFPS(1) #temporarily FPS=1 to use mflowfps

super=SVSuper("{gpu:1}")
vectors=SVAnalyse(super, "{}")
SVSmoothFps(super, vectors, "{rate:{num:"+String(X+1)+", den:1}}", url="www.svp-team.com", mt=1).Subtitle("SVPFlow")

AssumeFPS(FrameRate(Source)) #return back to normal source framerate for joining
Trim(1, framecount-1) #trim ends, leaving replacement frames

Source.trim(0,-N) ++ last ++ Source.trim(N+X+1,0)
}

You never said, in the original post, what reason you had for replacing those individual frames. If those frames are corrupted (blank, full of noise, photographer flash, etc.), I have a script that will automatically detect and replace (using motion estimated interpolation) those bad frames. Here is a link to the thread where I created the script:

Finding individual "bad" frames in video; save frame number; or repair (https://forum.doom9.org/showthread.php?t=174104)

I'll tried those scripts. Thanks to all of you!
