I need some help with interpolation videos, lots of detail in post

[bradwiggo]

I have been trying to get some interpolation right for a few weeks now, and I need some help with it. I have tried a lot of things, all of which I will go into detail about in this post.

I started trying to interpolate videos as I read that a lot of TVs did this and wondered if there was a way I can do it on my computer. I went on youtube and searched for interpolation and found loads of videos of varying quality. After a while I started to look more specifically at interpolations of animation, as I am a fan of animated movies. I found numerous examples of interpolations of animation, this probably being the best I found: https://www.youtube.com/watch?v=sPAP...A&index=4&t=0s

I also focused on this one as in the comments of the video the person who uploaded it said it was done with SVP, so that gave me a hint as to where to start.

I tried this tutorial: http://www.spirton.com/convert-videos-to-60fps/
and wasn't impressed by the results. The camera looked smooth, but motion on screen still looked like it was running at 30fps.

I then made a post about this: https://forum.videohelp.com/threads/...e3#post2524201

and I got a lot of useful advice, which allowed me to produce a much better interpolation, the best example of which is probably this: https://1drv.ms/u/s!AiOx2LWATSlvzjpQLo1axA8V3dqT

However, it still didn't look as good as the youtube video. There are also quite a few duplicate frames in that video.

The script I was using to make that video was something like this:

PluginPath = "C:\Users\bradw\Downloads\MeGUI-2836-32\tools\lsmash\"
LoadPlugin(PluginPath+"LSMASHSource.dll")
LoadPlugin("C:\Users\bradw\Downloads\MeGUI-2836-32\tools\avisynth_plugin\svpflow1.dll")
LoadPlugin("C:\Users\bradw\Downloads\MeGUI-2836-32\tools\avisynth_plugin\svpflow2.dll")
LSMASHVideoSource("C:\Users\bradw\Documents\file.mkv") 
AssumeFPS(24000,1001)
super=SVSuper("{gpu:0}")
vectors=SVAnalyse(super, "{block:{w:16}}") # 16 is the default, you can try 8, 24, and 32 also
SVSmoothFps(super, vectors, "{rate:{num:5, den:2, algo:2, scene:{mode:1}}}", url="www.svp-team.com", mt=1)

My original source for these tests is here: https://1drv.ms/v/s!AiOx2LWATSlvzjxoZFpKvN_R2yu_

I am not very knowledgeable on the subject of interpolation, nor am I of avisynth or video encoding in general, however I do have a basic understanding of these scripts.


Any advice on what I can do in order to make my interpolations look smoother would be greatly appreciated, I hope I have provided enough information and enough samples in this post, but if you need more, I will be happy to find them.

Also, I use MeGUI to run these avisynth scripts.

My computer specs (incase it matters):

AMD 10-7300
8GB RAM
1TB HDD
Radeon R6 integrated graphics.
It's a Lenovo Z50-75 laptop.

Thanks, I will try those out, are they for avisynth?

Also, where do I put the path for the input video?

Frame interpolation is always going to be a hit or miss, when it hits, you'll get a nice looking interpolated frame, when it misses, you'll get a frame with artifacts. For example, when the original frame rate is low and there's a fast moving object and you're trying to achieve a frame rate that is more than twice of the original, more than likely it's going to be a miss.

However, there should not be any difference on "smoothness" between all of the different converter filters because they all shared the same backbone. What you should be focusing on are the differences in the interpolation quality and their handling of artifact.

To get less artifact, you should only do double frame rate conversion. So if your source is 24fps, you should be doing 48fps conversion instead of 60fps because interpolating 1 frame in between frames is always going to have less chance of artifact than interpolating 2 frames in between.

Why does my video look less smooth than the youtube video if the interpolation is the same?

Because you're using blend mode?

What should I change to stop that? Is that the Scene Mode argument?

I don't know, I'm using the older 3.1.7 version. There was an option called "artifact masking", you have to disable it, turning it to "strongest" will blend the frames.

the 3.1.7 version of what, svpflow?

Also, do you know how to use the script that StainlessS posted, as I don't know how to set the input video.

I have tried to gte this working but I have a few questions:

1. Where do I put the path to the input video? As meGUI gives the error "the scripts return was not a video clip"

2. Is should I use that as a .avs file for MeGUI, is that the right way to use it?

It said it couldn't open the file, it might be because I was using an mp4 or mkv file, not avi, do I need a different instruction to avisource?

What, you aint even sure if its mp4 or mkv ?

Not really sure that you should be posting in the Avisynth forum if you have not even attempted to figure out how to use Avisynth.

Suggest that you look at ffmpegsource or LSMASHSource (I rarely use either and convert all except VOB/MPG to avi, doing anything else usually
involves too much messing about trying to figure out the better source filter to use).
I do not recommend DirectshowSource.

I have a few files that are mkv and a few that are mp4, I can't remember which one this is. I have a basic knowledge of avisynth, but I don't know a huge amount about it.

[StainlessS]

Suggest LSMASHVideoSource(), and LSMASHAudioSource()
if one of these, mov, mp4, m4v, 3gp, 3g2, mj2, dvb, dcf, m21.

No idea what is best for mkv.

[johnmeyer]

I suggest that anyone trying to help the OP read the following because this thread is going down the same path as the thread he started a month ago on Videohelp.com:

Why don't my interpolated videos look as good as examples I see on youtube?

The problem is that everyone there -- and it is now true of the posts so far in this thread -- didn't initially understand the real problem at the heart of what he is trying to do. Here's that problem:

He wants to create smoother motion for animation and, as most people reading this know, animation repeats some frames, but not others, and does so in a way that does not follow a regular pattern, like telecine patterns usually do. So, if you simply apply MVTools2, SVP, or Interframe motion estimation to create more frames, you end up with a real visual mess, and the motion doesn't look that much smoother.

What first needs to be done is to replace the dups in a way that takes into account the variable time gap between frames that are actually different. Thus, I don't think you can simply use FillDrops() (a function I've posted many times) to replace all duplicates, first because there are some situations where there is more than one dup in a row which will cause FillDrops() to fail, but also because some gaps in time between non-duplicate frame are going to be larger than others. THAT is where you want to insert a motion estimated frame, after you've deleted a duplicate, NOT at the place where the dup is removed.

One thing I would suggest to the OP, now that he is here on doom9, is to take a look at this thread I started several years ago:

Automatically fix dups followed (eventually) by drops

What I tried to do in that thread -- and with the help of some old code written by Didée I was able to accomplish -- was measure the temporal gaps between each non-dup frame. Then, after I deleted each duplicate, rather than insert an interpolated frame at the location of the deleted frame, I instead used my "gap logic" to insert an interpolated frame at a nearby location that had the biggest apparent jump in motion.

It wasn't perfect, but I think I was on the right track, and I believe that it might be a way to fix the OP's problem.

BTW, if someone can figure this out, what he wants is actually something that might be useful to other animation fans.

Just use it and you'll see.

So far I see 3 approaches to deal with detected artifact.

1. Do nothing, rely solely on the ability of mvtools. You'll see artifact but get smoothness.

2. Don't change anything. Keep the object as to the original. You'll see smoothness on objects that aren't artifact detected and stutter on objects that are. No artifact.

3. Blend the frames. Since no new interpolated frame has been created, you basically ended up with what the original looks like on playback.


The scripts StainlessS referred are approach 1. The youtube one is 2. Your script as well as framerateconverter is 3.

1. Do nothing, rely solely on the ability of mvtools. You'll see artifact but get smoothness.

2. Don't change anything. Keep the object as to the original. You'll see smoothness on objects that aren't artifact detected and stutter on objects that are. No artifact.

3. Blend the frames. Since no new interpolated frame has been created, you basically ended up with what the original looks like on playback.


The scripts StainlessS referred are approach 1. The youtube one is 2. Your script as well as framerateconverter is 3.

Which script would I want to use for option 2?
