[HELP] Upscaling VCD .dat files problem - Printable Version +- Selur's Little Message Board (https://forum.selur.net) +-- Forum: Hybrid - Support (https://forum.selur.net/forum-1.html) +--- Forum: Problems & Questions (https://forum.selur.net/forum-3.html) +--- Thread: [HELP] Upscaling VCD .dat files problem (/thread-4182.html) |
Upscaling VCD .dat files problem - Miranda - 14.08.2025 I added two .DAT files to Hybrid, both sides of a VCD (MPEG-1). Hybrid correctly reported these as 25fps progressive. However, when denoising and upscaling to 720, the footage is being slowed down resulting in twice the running time, but to confuse matters the running time of the exported files still shows as 25fps. Any suggestions what could be happening? RE: Upscaling VCD .dat files problem - Selur - 14.08.2025 Without a debug output: No. Additionally, when handling vcds best repack the content with https://www.videohelp.com/software/vcdgear (Windows only). Cu Selur RE: Upscaling VCD .dat files problem - Miranda - 17.08.2025 Thanks for the above link, I've now converted the .dat files to mpg. I've tried numerous DeBlock settings within the DeBlock_QED filter, but I'm still seeing lots of blocking/compression artifacts when upscaling to 720p. Any suggestions? I need to go up to 1080p on this for a Blu-ray project. I'd forgotten just how poor VCDs look. sample VCD clip RE: Upscaling VCD .dat files problem - Selur - 17.08.2025 Normal deblocking filters will only help with the first iteration of encoding, if you reencode blocking content again the will not really help unless you crank the strength up. (machine learning based deblocking like might help better) Have you tried something like MCTemporalDenoise with a high preset, SpotLess iwth tr=3 and or SMDeGrain? i.e.: # Spot removal using SpotLess ![]() to get things starting? The problem with such content is to rescue some sharpness. ![]() Cu Selur Ps.: there seems to have been a mix up with pc vs tv luma scaling in the past of this clip, so using something like clip = core.std.Levels(clip=clip, min_in=36, max_in=212, min_out=16, max_out=235) Ps.: conventional filtered: script, clip stabilizing is a pain with that intro,... RE: Upscaling VCD .dat files problem - Miranda - 17.08.2025 Do you think it's best to deblock and denoise and then upscale the output files? RE: Upscaling VCD .dat files problem - Selur - 17.08.2025 Doesn't really matter if you use a lossless temporal file as intermediate or not. Adding QTGMC(Filter) with InputType=3 does help with the flickering of the text in the intro a lot. RE: Upscaling VCD .dat files problem - Miranda - 18.08.2025 # Spot removal using SpotLess I can't seem to match these settings - what are the actual settings in the filters? RE: Upscaling VCD .dat files problem - Selur - 18.08.2025 you can skip ', smoother="zsmooth"' and ', opencl=True, device=-1' in case that helps,... not at home atm. RE: Upscaling VCD .dat files problem - Miranda - 18.08.2025 I seem to be encountering some ExitCode crash problems with Vs filtering - debug attached. I'm also not able to get a preview window. Can I do the same with Avisynth? edit: same crashing with Avisynth filtering.

RE: Upscaling VCD .dat files problem - Selur - 18.08.2025 # Imports => Check the Vapourynth Preview. If the preview still does not work, you need to check your setup and the used filters.

Assuming the filters are all present in Avisynth you could use that. Cu Selur |
