Color Correction?

[beav]

Hey! can anybody help me get the colors on my dvd to look like the picture I just posted. I'm not really sure how to do it, I keep destroying the lines and over doing the color.

[beav]

Im filtering this through avisynth by the way.

Why do you want your video to look like the image posted? The picture is too red and black levels are too high. It has the same red tint and washed-out lines you complained about in earlier posts. If high black levels and lots of red is what you're looking for, work with Avisynth color adjustment filters (ColorYUV, Tweak, Levels), histograms, vectorscopes, pixel samplers, and RGB controls found in VirtualDub (ColorMill, gradation curves, RGB modifiers, etc.).

Other than giving general advice like the above, no one can help if they don't know what your video looks like.

I guess you're right. I'm trying to hard to get perfect results from a source where perfect results will never happen. I just need to give up on this source and go with what I have.

The colors in the VOB file are already pretty close to the sample image. What are you using to view the VOB? Maybe that's the source of your color problems. Different programs/hardware can convert the YUV (in the file) to RGB (on the screen) in different ways.

This will get you a little closer: ColorYUV(off_y=-1, off_u=1) but a wider variety of shots to compare to would be helpful. You can also try using the ColourLike() filter.

There appears to be a strange weird kind of line along the side of the window in this sample and jpeg. And I can't seem to fix. Is it some kind of dot crawl cause aliasing filters dont work.

[beav]

The jpeg I posted at the top of this thread doesn't have this problem. Is it removable?

[jagabo]

I don't know what you're talking about. Be more explicit.

The jpeg I posted at the top of this thread doesn't have this problem. Is it removable?

Of course it is, just edit your posts in the so-called "Advanced Mode" or something.

And please, use PNGs next time, because lossless JPEG is not supported by web browsers thus far

In the first screenshot you can see that the lines look fine where the circled area is, but in the second screenshot where the circled area is there is a weird line kind of grain. Might be aliasing or dot crawl. I can't seem to remove it with antia-aliasing filters.

[jagabo]

You should post non-resized PNG files to show such fine detail. Resizing and JPG compression both produce artifacts so it's hard to tell what's in the source and what was caused by the processing.

But looking at the MVK file: What you're seeing is a mix of noise, oversharpening halos, and DCT ringing artifacts, all exacerbated by over compression. Don't sharpen as much, use better noise reduction, and higher quality encoding.

Higher quality encoding may not be necessary if you get enough noise reduction. If you don't want noise reduction (ie, you want to retain the grain noise) then you must use much higher bitrates and a higher aq-strength value in x264.

In the first sample I'm about to post, the lines in the area I circled earlier are cleaned up and dont have this weird moving line problem in that particular area. However in the second sample I'm about to post (my version) I can't seem to get the same results with any aa filter, denoiser, or dot crawl filter. It's almost impossible to remove this problem in my version. Does anybody know how I can fix this problem?

[beav]

The area I'm referring to is the same area I have circled in red on the above jpegs.

[jagabo]

Try something like:

Mpeg2Source("dvd.d2v", CPU=6, Info=3) 
TFM(d2v="dvd.d2v")
Santiag()
McTemporalDenoise(settings="very high")

[beav]

I tried using yadifmod with these settings yadifmod(edeint=nnedi2()) and it kept the sharpness, removed grain, and fixed aliasing. However, it is a little hard on the eyes it like hurts them or looks weird to me for some reason. Can anybody recommend some settings that aren't so hard on the eyes? It could be because yadifmod deinterlaces everything or something.

[beav]

my script looks like this:
# Set DAR in encoder to 4 : 3. The following line is for automatic signalling
global MeGUI_darx = 4
global MeGUI_dary = 3
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\TIVTC.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\yadifmod.dll")

DGDecode_mpeg2source("clip")
AssumeTFF()
TFM()
TDecimate(mode=2, rate=23.976)
yadifmod(edeint=nnedi2())
crop(4, 0, -2, 0)
spline36resize(720,540)

[jagabo]

Why would you use YadifMod() after TFM().TDecimate()?

[beav]

Because it fixed a lot of the problems with the lines, grain, and aliasing. I'm only using it for clean up, not for deinterlacing.

[beav]

is it a bad idea to use yadif for clean up?

[beav]

Hey guys! I have a question about the ColourLike() filter that jagabo mentioned before. Does it affect the colors of my whole video, or just the frame/scene I choose?

[poisondeathray]

is it a bad idea to use yadif for clean up?

In general, yes - bad idea.

It's not a "clean up" filter, it's a deinterlacer (and not a great one, it leaves artifacts behind, "marching ants")

Use the right tool for the job

Hey guys! I have a question about the ColourLike() filter that jagabo mentioned before. Does it affect the colors of my whole video, or just the frame/scene I choose?

Yes it affects entire video , but you can apply a certain filter to specific frames by dividing up the video with Trim() and then joining them

Or several other ways like ApplyRange, or ReplaceFramesSimple or similar filters
