set output DAR lags to prores - lessbones - 06.05.2023
Hey all-- I've been using hybrid for some time now to deinterlace and convert videos captured as NTSC Lagarith .avi to Prores .mov files, and for some reason I've never been able to properly set the output DAR (or the input PAR?)
With ffmpeg using yadif2x to deinterlace I would use the flag "setdar=4/3" for the output, but the quality of the deinterlacing is much better in hybrid. I've attempted to force the input PAR to 8:9, which I think is the right aspect, but forcing doesn't seem to have any effect whatsoever between these two containers/codecs.
Basically start with a 720x480 file, and I end with a 720x480 file, both have DARs of 3:2 and the only way i've found to change the DAR flag is to recreate the containers after the fact with ffmpeg...
this is the input mediainfo:

Alternate group : 1RE: set output DAR lags to prores - Selur - 06.05.2023
Hybrid doesn't set DAR, but PAR.
PAR can be changed through "Crop/Resize->Base->Pixel Aspect Ratio (PAR)", that said, there might be a bug somewhere.
-> Share a debug output. (read sticky)

RE: set output DAR lags to prores - lessbones - 09.05.2023
Hey thanks Selur--
here's my debug:
RE: set output DAR lags to prores - Selur - 09.05.2023
Okay, input PAR is 8:9 = 1.333.... ~ DAR: 20:15 which in the debut output get's passed on t the encoding call:
"/usr/local/bin/vspipe" "/Volumes/xxxx/encodingTempSynthSkript_2023-05-08@18_00_08_0410.vpy" - -c y4m - "/Applications/Hybrid.app/Contents/MacOS/ffmpeg" -y -noautorotate -nostdin -threads 8 -f yuv4mpegpipe -i - -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv422p10le -strict -1 -vsync 0 -vcodec prores_ks -profile:v 1 -vtag apcs -aspect 20:15 -metadata encoding_tool="Hybrid 2022.03.20.1" -f mov "/Volumes/xxxx/CP_Hi8_703_2023-05-08@18_00_08_0410_03.mov"So, try setting Crop/Resize->Base->Pixel Aspect Ratio (PAR)->Input PAR to 38800:42651 and depending on what you want to do with it later adjust 'Convert output to PAR'.

After setting the PARs Adjust 'Picture Resize' and 'Letterbox' and check the 'Vapoursynth Preview' to check what is happening, this way you should be able to achieve what you want.

great, thank you! I'll give it a shot and let you know--

what kind of file? Name?
RE: set output DAR lags to prores - lessbones - 16.05.2023
finally got a chance to test this, and yes, it does work as expected. I guess I just simply didn't know which was the right PAR to use--
the only one little weirdness is that hybrid doesn't seem to support enough digits to properly get the entire pixel ratio for NTSC into the dialog boxes... it only supports 3880/4265, so the output ends up being ever so slightly less than perfectly 4:3--
RE: set output DAR lags to prores - Selur - 16.05.2023
will look into that after work
RE: set output DAR lags to prores - lessbones - 16.05.2023
Thanks-- one other thing while you're at it-- is there a way to get it to save the desired values for the PAR fields? Every time I reopen hybrid, even saving a default setup it reverts to 1:1
thanks again
RE: set output DAR lags to prores - Selur - 16.05.2023
Input PAR, like all input related options, can't be saved.
