The source doesn't have too much Dotcrawling & Rainbow, since it's a little difficult to find them on most scenes (some scenes are REALLY heavy)
But on the other hand, the combing is a huge problem because it ruins most of the quality, and the sad part is, the source is progressive, and not interlaced.
Can anyone help me out here? thanks!

(NOTE: I'm using AviSynth
If anyone can lead me to a site that has a lot of description that can restore quality from AviSynth please?,
I'm going to need A LOT of research to restore quality like Dotcrawling & Rainbow I'm trying to remove, thank you!) ]]> Restoration themon-master https://forum.videohelp.com/threads/420400-Is-there-a-way-to-remove-all-Dotcrawling-Rainbow-and-Combing Need advices to improve this video https://forum.videohelp.com/threads/420369-Need-advices-to-improve-this-video?goto=newpost Thu, 09 Apr 2026 16:56:51 GMT Hi everybody, Nearly 2 years ago, I recorded a diving training session with a cheap action camera : 720P-30 fps (There are a lot of duplicated frames so the real frame rate is around 20 fps).

Nearly 2 years ago, I recorded a diving training session with a cheap action camera : 720P-30 fps (There are a lot of duplicated frames so the real frame rate is around 20 fps).

I decided to improve the quality of the video.

MOVI0026-short.avi : is a sample, directly stream copied from the original video
MOVI0026-short-rife.mp4 : is the improved sample with the folowing avisynth script used to improve.

Code:
FFMpegSource2("MOVI0026-short.avi")

Spline36Resize(640,360)

ConvertToYV12()

QTGMC(Preset="Slow", InputType=2, ProgSADMask=12.0, Sharpness=0.2)

SMDegrain(tr=2, thSAD=300)

Tweak(sat=1.15, cont=1.05, bright=0, coring=false)

LSFmod(strength=75)

Spline36Resize(1280,720)

Limiter()

Z_ConvertFormat(pixel_type="RGBPS", colorspace_op="709:709:709:limited=>rgb:709:709:full")

RIFE(model=11, fps_num=60, fps_den=1)

z_ConvertFormat(pixel_type="YUV420P10")
What would you recommend to do, in order to improve it ?

Best regards

Is this dirt that I should remove, or is that old grease? Do I need to clean it with isopropanol?

Thanks in advance

With your great help I've been doing my own VHS rips/QTGMC deinterlace - briliant result. :-)

Recently I've received a file from someone, of unknown origin and it is totally weird to me.

I've got interlaced AVI that claims to be from VHS (it was) but have following specifics (see below)
I'm sure it is BFF (checked and de-interlace produced OK results -in time.TFF was jumping back-and-forth. Codec also looks unfamiliar.


The problem to me is - the image jumps up and down. Naked eye observations in VirtualDub are showing
Image 0,1,2 OK
Image 3,4,5 shifted, for me should be shifted down
pattern repeats.

The most visible part is on white title "Within", or at triangle logo on right.

Attaching 30MB (8sec) of original AVI (I've just cut the beginning of file so for example VLC say "no index", and this is just for the cut version, no complaining on full vid.


What I've tried was VirtualDub2, Avisynth+ , QTGMC as below:

#my blind guess
FFmpegSource2("dyn.avi")
AssumeBFF()
SeparateFields()
normal_fields=SelectEvery(6,0,1,2)
shifted_fields=SelectEvery(6,3,4,5) # those I guess I need to shift down
fixed_shifted= shifted_fields.Crop(0,0,0,-1).AddBorders(0,0,0,1)
Interleave(normal_fields,fixed_shifted)
Weave()

ConvertToYV12(interlaced=true)
QTGMC(preset="Slower", EdiThreads=16)
