Info: cleaning up dirty frames for scenes — Page 2

Just wanted you to understand beforehand that I'm talking about the 24 frames you posted on your site.  I don't remember if you said not to post it anywhere that's why I'm asking.

yeah, i understand.

it's ok. as long as it's still frames here.

Ha. No I was talking about a 576p clip.  Well I could show a few of the stills but it wouldn't demonstrate much in the way of the stabilization. 

Perhaps I can just tell the process how I did it.  I flipped it and then used something called centertracker to focus on the sprockets on the side and then it feeds adjustment parameters to avisynth.  It works very well and since it is only looking at the holes there is never a chance that it will lock onto "bad" motion in different scenes.

well in that case, go ahead then.

put it up on vimeo. you have them

all password protected anyways.

yeah, i would like to see it to.

Here it is.  It's been flipped, stabilized, and cleaned.  Thoughts?

good job althor. i guess cropping and stretching would help in

making another comparison. i haven't looked at our version

in awhile. keep it up.

here's another 30 seconds of the previous clip.

more raw red footage from the test reel.

lots of noise, dirt and scratches going on.

it has one of my favorite parts, where the stormtrooper

on the far right bumps his head on the door!

it was a long time before i ever noticed it,

and there was even a sound effect for it. ha ha

I've also been playing with capturing the optical audio tracks on that 1 sec clip I posted the other day.  I've managed to capture it by cropping each channel with avisynth and saving it as a 24bit bitmap and opening the waveform image in a program called imagetosound.  I've managed to capture it at 32400 samples per second with 8bits per channel(limited by the resolution).  I'm wondering how you guys are going about capturing it and what kind of quality it achieves? The 1 second I got sounds pretty awesome lol.

EDIT:  Little off topic but I didn't know where else to put it.

you should start another thread about the optical track

conversion, and discuss it there.

we have access to other equipment that can work

with getting the audio.

here are some more uncropped

examples from the last clip,

including where the stormtrooper

hits his head! haha

you might want to overlay these

over the originals to see the

cropping:

here's version 0 of trying to recolor the

first clip of the trash compactor..

pretty rough..

and here's an improved version 1,

but there's still a reddish tint to it:

Here's the motion-compensated dirt removal function I was using for the now-defunct SWOLT project.

Warning: It cleans excellently while preserving detail, but don't use it for any shots containing stars.

Note 1: You may want to set clmodeY to 18. See the RemoveGrain manual for explanations of what the different modes do and what the ups/downs of each one are.

Note 2: It only works on clips in planar color-spaces; e.g., YV12. Furthermore, it won't clean frames at scene-changes.

I do not. I only have the still examples in my SWOLT Progress thread.

I can use the JSC to generate a small sample when I get home, but I have a better idea: upload a particularly dirty shot and I'll re-upload it with the RemoveDirtMC function applied. Sound good?

RemoveDirtMC2  is used in the script I posted in post 2 or 3.  The workflow for the script is:

Stabilization (Depanestimate/Depanstabilize)

Dirt Removal (RemovedirtMC or RemovedirtMC2 depending on version)

Degraining (Mvanalysemulti/MVdegrainmulti)

optional interpolation(Manalyse/Mflowfps)

optional color adjustments (Coloryuv/autolevels/levels)

There are other parameters for sharpening and blurring but that's the basic gist of things.

Here's a page that has collected a lot of the motion comepensated dirt removers.  You'll notice removedirtmc is now up to version 4 and even removedirthq.  Each one uses the prior version to build upon, I think. So you can't call removedirtmc4 without also having 1,2, and 3.

EDIT:  Looks like Removespots is the one that is dependent on the earlier versions and Removedirt is only up to removedirtmc2 and removedirthq.  I was looking at the wrong functions lol.

I've seen that page before. The RemoveDirtMC2 has a bug. That is, it says "SelectEvery(clipb, 7, 1)", but it should say "SelectEvery(clipb, 7, 3)". Similarly, it says "SelectEvery(clipb, 5, 1)", but it should say "SelectEvery(clipb, 5, 2)". It only works because "SelectEvery(clipb, 3, 1)" makes sense for a value of 3 and everything else is commented-out.

Furthermore, I'm not too fond of the RemoveDirt function that RemoveDirtMC2 calls. The final call to RemoveGrain removes too much detail. If you use it on the infamous speeder shot in GOUT ANH, you'll see small background objects pseudo-randomly turn on and off.

My version fixes the aforementioned bug and manages to use (internally) a RemoveDirt that preserves detail. It's not perfect, but it's the best I've been able to cobble together from the various sources on the WWW.

Nice,  I'll definitely check it out.

You know, I hate to say it, but I sincerely hope that the untouched warts and all scan is released -1. Those clips despite being dirty and faded look wonderful. Even with the expanding frame. ;) I dunno maybe watching degraded prints of films for too many years has warped my mind or something. How are you compensating for the red shift? It looks quite good for a start on these attempts.
