Any good Avisynth filters?
1 Attachment(s)
Been wanting to improve my Avisynth script for VHS tapes because its all over the place.
Currently I've been using a JVC HM-DM30000U outputting S-Video through a DMR-ES15 thats outputting S-Video to the I-O DATA GV-USB2, capturing through Virtualdub or AmarecTV with Windows 10 using the x264vfw codec. Not the best setup in the world but it has been working very well for me. The avisynth script I usually use is this Code:
SetFilterMTMode("QTGMC", 4) |
1) You can't use the same Avisynth script for all of your captures. Don't even think about it.
2) You wasted your time capturing to lossy codecs if restoration is what you want. The video you refer to in your posted jpg is not interlaced. You woudn't use QTGMC on it to begin with. That movie is hard-telecined. |

If your captures look like that screen shot in your first post, and you're satisfied with it, and your one-size-fits-all script works to your tastes, there's not much anyone can say. The concept of quality used to be an objective standard, many aspects of which can be can be precisely measured and described. But for many, quality is purely a matter of personal opinion. I'd advise that you don't change anything, ever. Why would you?
As for detailed advice, no one can help with a still image that looks as poor as the one in post #1. If my capture looked like that, I'd be forced to recapture to lossless huffyuv. But suit yourself. |

I do cringe when people copy/paste script online, and run them without adjustments. :mad4: The idea of ALL videos using the same script does raise my eyebrow. :huh2: Quote:
The only use for an ES15 chasing JVC D-VHS is where tearing exists, JVC cannot defeat, so JVC TBC off. ES15 takes over line duty, and then signal should next be passed to full frame sync TBC (DataVideo, Cypress). Quote:

You will get almost always frame drops without TBC. And dropped frames leads to audio sync errors. |

I've been doing some tests (and by tests I mean, at the moment, one tape cause I'm currently transferring all these D-VHS tapes I acquired off eBay) with just the VCR (no ES15), and I've had some good luck with 0 dropped frames or audio sync issues so far. Gonna keep testing though. Like I said obviously not the best setup, but it'l do for now. Quote:
I could never get used to Hybrid for some reason so I've been using Avspmod to do my encodings. Quote:
I did find that the 30000u picture quality without the ES15 is much better than with the ES15 though. Updated videos attached. Same script but without the Tweak command. Sorry I'm not so smart with this stuff. Obviously my setup ain't the best but I'm just going by with what I have for now until I can upgrade. |

Also about the tearing, it's weird. With the stabilizer off on some tapes there is some tearing, which gets fixed with the stabilizer. at the cost of jumpy video. However, the ES15 doesn't fix the tearing for me. So it's either jumpy video with the stabilizer on or occasional tearing with it off in that situation. |
Don't think the IO-Daga GV-USB2 is an ezcap clone, it seems to be based on a techwell (Renesas) chip:

I think decoding Ut Video should be faster. The downside, as you noted, is that you can't flag TFF to play your capture at 60fps in VLC. I use PotPlayer for this: http://www.digitalfaq.com/forum/news...nterlaced.html Quote:

Also, should I turn off the 3-DNR and Digital R3 functions on my deck or is it fine to leave them on? |

Just giving a 6 month update, I've updated my script and I'm pretty satisfied with the results.
Code:
SetFilterMTMode("DEFAULT_MT_MODE", 3) Some picture examples are attached, although not cropped and not upscaled. If anyone wants to see video examples I'd be glad to send them. I've been using this setup for a while now and I'm quite pleased with the results. Although unfortunately it'll never really be perfect. Since my VCR's TBC can't be turned off I have to deal with tearing (see the 5th attachment). Is there anything I can do to remedy it on my VCR? I took the lid off and if fixed a tear issue on one of my tapes but the others...not so much. And about the 3-DNR and R3, I have them both off and I'm not gonna be turning those on. 3-DNR is basically the stabilization + more noise reduction so that means a jumpy picture. R3 is just some sharpness setting thats unneeded in capture. Also is it a good idea to separate fields then weave between a CCD? |

If the GV-USB2 works I don't suggest swapping it out unless you have some major problems I've been using it for a year+ now with tapes and it's worked quite well. |
