Hello, a while back I started a thread on here asking about the process of converting VHS tapes to DVDs and spent much time working on my end to get to where I can do it on my own, but eventually got burned out and shoved the project to the side for a while. Reason being I couldn't get the technology right. I was thinking about it earlier today and thought I'd give this another shot. I have the equipment to convert tapes, but have had quality issues with the converted footage. When converted, the colors of the image will look desaturated or have some other random issue, and sometimes the sound will have deteriorated. I thought I'd start fresh and start over and ask here if anyone that converts frequently would like to share with me their methods of converting tapes. It'd be much easier than having me create my own, and will hopefully help me get to where I can convert tapes without trouble.

just a thought, having done some with much less than optimal equipment (but affordable for low volume home video capture/conversion) ...
if your source VHS is old and crappy and probably second generation copy or worse, and thus VERY noisy and wavy and colour-desaturated and with lots of artifacts and colour bleeding, then there is only so much you can do with it and it will never ever look as good as some of the conversion results posted here where the sources appear to be a lot cleaner - and I've tried, with great advice from the people here and elsewhere.
i ended up going back from vapoursynth to avisynth x64 portable and using filters like
deblock_qed (my capture equipment introduced bad blocking),
MDegrain1/2/3/4 with pre-filtered motion clip
cnr2 (an oldie but a goldie)
a deinterlacer (not necessarily QTGMC although you could use that) for 25i to 50p (at end, down to 25p for DVD)
RemoveDirtMC_SE to further denoise
aWarpSharp2(clip, chroma=6, thresh=128, blur=FCBW_blur, type=1, depth=10) # reduce chroma bleed, using edge mask from the luma to warp the chroma channels only
possibly ColorYUV to auto adjust
edit: care to post a sample un-processed input file ?

To get an idea of what I'm dealing with, check out post #94 at the link:
Feel free to check out that whole thread if you'd like.
Gee that is a really great source compared to every VHS tape I have !
Vdub2 and let youtube do the final encoding.
I am surprised at the good quality clip you posted.
Re flickering (I haven't looked at your sample), I tried a few and ended up with ReduceFlicker in avisynth.
# strongest ReduceFlicker RF_strength = 3 RF_aggressive = True clip.ReduceFlicker(strength=RF_strength,aggressive=RF_aggressive)

MediaExpress is part of the Desktop software they have in their website. The version before vdub2 works well for capturing. QTGMC is a script software and it has a learning curve, it is not easy to get going for the first time as it needs installing a lot of dependencies manually and sometimes fideling with the registry, so it is not a plug and play program.
