Help with interlaced or telecined frames - Believer - 17.02.2025
Hi,
Attached clip looks interlaced or telecined plus aliased i guess.
Struggling to deal with this.
Please help.
RE: Help with interlaced or telecined frames - Selur - 17.02.2025
That video is not interlaced or telecined. (no combing artifacts at all)
The original might have been, but this was recorded at 30fps which never was the frame rate of the original.
Best you can do is probably use sRestore to bring the clip to 23.976fps and then repair the lines.
Using:
sRestore(frate=23.9760) <= this removes the blends
QTGMC(InputType=3) <= this fixes most of the aliasing
helps a lot, adding BasicVSR++ fixes it some more.
(note that I use BasicVSR++ after QTGMC(InputType=3))
seems to produce a decent output. (script, clip)

Ps.: moved thread to 'Small Talk' since it's not really a Hybrid problem or bug.

Ok Thanks.
But QTGMC input type 2 & 3 are meant for deinterlacing. isn't it?
SRestore not working in Vapoursynth. Encoding stops in the middle all the time. So i can't able to remove blending or ghosting.

Quote:But QTGMC input type 2 & 3 are meant for deinterlacing. isn't it?0 for interlaced input. Settings 1,2 & 3 accept progressive input for deshimmer or repair. Frame rate of progressive source is not doubled. Mode 1 is for general progressive material. Modes 2 & 3 are designed for badly deinterlaced material.

Jumping in a source in the preview will not work, but encoding or progressively going through the source without jumping works fine here.
Check your RAM usage during encoding, iirc. it might help to lower the thread count in Vapoursynth if sRestore&co are running out of RAM.

Ok. Task manager RAM is Around 80%
Tried SRestore alone. That also fails while encoding.
Needs to change any settings? i have changed only frate to 23.976
RE: Help with interlaced or telecined frames - Selur - 17.02.2025
Strange.
Try another source filter.
Also does encoding the file without sRestore work fine?
RE: Help with interlaced or telecined frames - Believer - 18.02.2025
Now it is running. But very very slow. vspipe cpu usage is around 34-45%. RAM around 330-380 for vspipe, 300-320 for h264.
Is this because of too many blending?
RE: Help with interlaced or telecined frames - Selur - 18.02.2025
What does your Vapoursynth script look like?
If you are using BasicVSR++, that is what is slowing down the whole thing.
RE: Help with interlaced or telecined frames - Believer - 18.02.2025
No. Only SRestore filter running now. It just reached 20% after 9hr encoding a 20 min full video.
Did QTGMC input 3 separately. It was completed in 20min.
RE: Help with interlaced or telecined frames - Selur - 18.02.2025
Ah okay.
For me sRestore is faster, but my system probably is too (Ryzen 9 7959X, 64GB RAM).
