Help with function to delete and interpolate frames.

[Kuronoe]

Hello everyone.

I'm dealing with a video that has a lot of duplicate frames, thanks to that I need to use "DeleteFrame" and "InsertFrameMC" to correct it, because I already tried several automatic filters and none worked well.

The question is, me and a friend do not understand the language of avs to create the function, in vs it works, but it does not have some necessary filters for post-processing the video.

I'm trying to create a function that when inserting a certain frame, it will be deleted and interpolate the next one, without the need to repeat the filter over and over again.

For example:

FFVideoSource(\\video.mkv)
DeleteFrame(100)
InsertFrameMC(101)
DeleteFrame(123)
InsertFrameMC(124)
DeleteFrame(132)
InsertFrameMC(133)
DeleteFrame(147)
InsertFrameMC(148)

The function would work as:

FunctionAnyName(100, 123, 132, 147)

In this example, frames 100, 123, 132 and 147 would be deleted and those listed above would be added with "InsertFrameMC".

I appreciate the help.

Sorry for the explanation if it is confused.

I think what you want has already been done. The function FillDrops takes duplicate frames and replaces them with frames interpolated from the frames on either side.

function filldrops (clip c)
{
super=MSuper(c,pel=2)
vfe=manalyse(super,truemotion=true,isb=false,delta =1)
vbe=manalyse(super,truemotion=true,isb=true,delta= 1)
filldrops = mflowinter(c,super,vbe,vfe,time=50)
fixed = ConditionalFilter(c, filldrops, c, "YDifferenceFromPrevious()", "lessthan", "0.5")
return fixed
}

It only needs MVTools2.

Man, it worked really well in the video I'm working on here, I can't believe it, I usually did it manually.

I need to test on the other videos that I have this problem, it is usually NTSC> PAL conversion that causes this problem that I am seeing from the video making several jumps.

I tried Dedup, Dup and several others and nothing, this one did very well, I hope it works on the ones I left out.

Thank you very much.

To do it manually (ie, in cases where filldrops() doesn't work -- like multiple duplicates in a row) use ReplaceFramesMC(), not DeleteFrame() and InsertFrameMC().

I remembered the problem I had with "filldrops" in the past. This filter blurs some scenes, especially non-panoramic scenes. This filter worked well in the panoramic scenes that I have, I am thinking of using it only in some sequences of frames with a map or trim() (I don't know if it will work, I need to test it), something like:

FilterMap="[481 2049] [8007 9221]" #panoramic scenes
FilterLine=Filldrops()
ReplaceFramesSimple(FilterLine, mappings=FilterMap)

To do it manually (ie, in cases where filldrops() doesn't work -- like multiple duplicates in a row) use ReplaceFramesMC(), not DeleteFrame() and InsertFrameMC().

For some reason I had forgotten about ReplaceFramesMC(), I use InsertFrameMC() more often, but this filter doesn't do it in line either, but it is a better alternative than the method I mentioned above.

Thank for help, guys.
