Crop/Resize

[Selur]

Problem is:

a. 707x471 Hybrid should have thrown an error on preview creation. Uneven
width and/or height is only allowed with 444 as output color sampling.
b. the preview call

# converting to mod1 compatible format
clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, range_s="limited")
# cropping the video to 707x471
clip = core.std.CropRel(clip=clip, left=1, right=12, top=8, bottom=1)
# cropping the video to 707x471
original = core.std.CropRel(clip=original, left=1, right=12, top=8, bottom=1)

Preview fails since original is still YUV420P8
is missing a conversion to YUV44P8 for the original

-> I'll look into it.

Note that, even after I fix the bugs, you either need to adjust your cropping values or your output color space.

Send you a link via PM to a version which should:
a. check the output resolution against the restrictions of the output color space and throw an error on violation of the restrictions
b. adds the missing color conversion during filter preview

Is there is a chance to  "Save Filter" order and cropping values when Configuration save/Configuration save under current name?

[Selur]

Cropping values are not Vapoursynth specific so they are not saved those configurations.
FilterOrder should be saved.

I'll add the FilterOrder to the Vapoursynth configurations. (same for Avisynth)

No clue what the error is,... it would help if you wrote the error message,...

Weird - can't reproduce it either this time.
It was error related Vapoursynth editor.
If it'll appear next time I write as much as possible info.

Okay, this is not a Hybrid bug, but a bug in one of the filters or Vapoursynth itself.

it randomly crashes,... every few times,.. -> I'll so some more testing and if I can't identify the culprit I'll try to contact the Vapoursynth authors over at doom9s.

Okay, it's definitly the resizing, without:

clip = core.fmtc.resample(clip=clip, kernel="spline16", w=1280, h=530, interlaced=False, interlacedd=False)
original = core.fmtc.resample(clip=original, kernel="spline16", w=1280, h=530, interlaced=False, interlacedd=False)

the script works fine.
-> I'll try to contact the fmtc author. (https://forum.doom9.org/showthread.php?p=1927388)
