You also need a Y/C signal path to the card, because its comb filter is mediocre, again by a high end VCR with S-Video output or a Panasonic DMR in passthrough mode.

For what I read from your link, The EDIT=ON is like booting a PC in safe mode, where it turns off all post-processing, which is a good thing since vapoursynth filters will do a far better job And also how is the line TBC in those Panasonic DMR compares to the one in VCR? |

The N.R. cannot be disabled without turning off the lineTBC. They work as a pair. I never disable the lineTBC, except when I use a DMR as passthrough. There is no sense in capturing without a line correction, so I have no example to show.

Be also aware that tapes in marginal conditions also need a frameTBC, rare today and expensive. Hopefully you'll not be in this case.

I agrre, that it hass far too much luma gain, that's why I put a potentiometer between VCR and ES10.

Here a sample on my hardware. A comparison between a capture from a Panasonic VCR without lineTBC versus the same VCR adding the ES-15 with N.R.=off. I still see some noise reduction. If you say the N.R. can be completely disabled, it could be a low-pass filter effect of the added device on the high frequecies, so a spacial effect more than a temporal effect, I do not know. But the noise reduction is there, at least in my experiments.
https://imgsli.com/OTkyMDk P.S. I am providing a field analysis only because the original vhs has even field corrupted, and we were trying to fix them with the ES-15, without success.

Depending where I look the Panny has retained more details (or just introduced artefacts?) or smoothed away details at other parts of the picture. The vertical shift is a bit annoying for the comparison.
If one picture is the top and the other picture is the bottom field the noise comparison would be moot. Not sure about my conclusion though. Last edited by Sharc; 12th March 2022 at 11:08. |

Some more reading about the impact of passthrough and its settings etc.

I am comparing odd field versus odd field, cannot do at frame level for this capture because the even fields are bad.
The shift is caused by the lineTBC of the ES-15, framing the active area in a different region (1 pixel shift to the right, 1 pixel shift to the top). Here a comparison where I aligned the 2 captures (YUY2 converted to RGB to be able to cut/add 1 pixel in width): https://imgsli.com/OTkzNzE The lineTBC effect is evident in the right boot of the austronaut (and many vertical lines), together with a general noise reduction (the column on the left for example). EDIT: A "setting guide" for Panasonic DVD recorder used in passthrough: https://forum.videohelp.com/threads/...29?mode=hybrid

From what I have read so far, here's what I think happened with the TBC progression:
It all started out in the professional field with those expensive device that can do time base correction and frame synchronizing for broadcast. Eventually it came down to the consumer level where the TBC feature (not the frame synchronizer) was somewhat implemented into VCR, with each brand adding their own sauce into the mix, like noise reduction. Those sauces however, became the headache we have to deal with today. The limited buffer size in the VCR TBC also limited its effectiveness on fixing crappy sources, it was enough for most but not the crappy one. At about the same time, consumer level digital mixer became available (It was not cheap though). As a part of the package, these mixers came with TBC and frame synchronizing at the same time, where they have enough memory to do a full frame TBC (52x lines) at once compares to 2 lines TBC from VCR. They called it "infinite window TBC". So, if my assumption is correct, to get a high quality VHS transfer, all we need is a decent VCR that adds no additional digital filters and has a s-video output, a digital mixer and that's it. There is no need for a high end VCR with line TBC or TBC capable DVD recorder as passthrough, which are inferior to infinite window TBC, avoiding all unnecessary pitfalls. And there is no need for those ridiculously expensive so called "external frame TBC" basically just for frame synchronizing. |

Anyway, BMD devices can provide solid results if you have a full TBC between the VCR and the capture card. (That is, some Sony or Panasonic DVD recorder deck with internal TBC or some dedicated devices providing a the very least a genlock). Quote:

I just brought a JVC HR-S4800U for $125, pretty good reasonable price. |

Does the Hauppauge USB able to record VHS stereo? I have an anime VHS that stated on the cover to be "mono-stereo-Hi-fi", so I supposed it plays Hi-fi stereo? But Hauppauge was not able to record the stereo properly? I checked the recorded audio in Adobe Audition, the left and right channel are exactly the same.
