VCR settings, Virtualdub settings?
3 Attachment(s)
Hey!
I finally have the time to capure my vhs (tvrips, cartoons, personal tapes etc) and I want to be sure that everything is set correctly. VRC (HR-S7600EU) Should I change someting here? TBC button is always on. Attachment 15798 Attachment 15799 Virtualdub 1) Crossbar Thing -> S-Video selected & Link related streams is disabled (Pinnacle 710) Attachment 15800 Virtualdub: 2) Device -> Device settings -> all disabled ("switch audio source when changing video sourse" was on) 3) Video -> Preview 4) Video -> Compression -> Huffyuv v2.1.1 -> Configure -> I disabled "enable full size output-buffer" 5) Audio -> Volume meter 6) Audio -> "Enable audio playback" is disabled 7) Capture -> Timing -> I disabled "Drop frames when captured frames are too close together" & "Insert null frames when captured frames are too far apart" Should I check/change something else? I hope that I didn't do anything wrong. Also, I put a vhs and I noticed that the average rate was 24.8-24.9 instead of 25fps (I've set it as 25fps in settings) and I had some issues with Sync: Current error. Do you think that it's my tape's issue or should I change something to fix it? Thank you in advance! :) Ps. I'm using windows 10. I had freezes issues with my windows 7 laptop. |
Any tips? :)
Also do you thing that I have to change brightness, contrast etc before capture or after? |
Why do you want generic rules? You should experiment with your own material what is best. The setting of the JVCs are tape and source dependant.
There are tens of posts about this; some comparison here https://www.digitalfaq.com/forum/vid...html#post70663 and here https://forum.videohelp.com/threads/...re-%28again%29 Quote:

I tried to change some VCR settings. Picture control (Auto, Edit, Soft, Sharp) and Digital 3R (on/off). I tested 1 cartoon tape. I guess I should test more tapes. But for this tape, D3R as On was always better for every P.C option. As for P.C. option, Edit and Sharp was the best. Although Sharp is more clearer/sharp but it's interlasted compared to Edit option and for same reason the frames are not centred in the same way even tho it's the same frame. I don't why. :hmm: (TBC and B.E.S.T was always on.) I guess audio is always the same, right? (I just pick uncompressed option in Vdub). btw, for some reason, everytime I rewind my tape (after it finishes the Rewind, I mean), VDub loses the signal (black image) and I have to press play and Capture to make it work. It makes difficult for me to start capture before the tape starts so I can capture from time 0. Is there anything I can do? :hmm: |
Cartoons are not ideal for a testbench.
Post a raw capture segment, not a vlc snapshot. The comparison may be affected by any filtering in the player. Generally, with a "edit" mode better to use "D3R" off, with a "normal" mode better to use "D3R" on, because with this mode there is a spatial and temporal noise reduction leading to a "softer" picture. Generally, these are the 2 best combination, YMMV. The mode "sharp" is enhacing the edges but introducing problems: https://imgsli.com/MTM2MDk2 (look at the vertical lines in the cilinder) and increase the halos. I would not use this mode. If you plan an AviSynth restoration with denoise and sharpening, operations that are more effective with AviSYnth than what you can achieve with the VCR, the general rule is to use "edit" + "NO D3R", but on my material I saw exceptions, so experiment yourself https://www.youtube.com/watch?v=X1jp...cMC7e3mAr6svPh Quote:
B.E.S.T. always on when you play tapes recorded using a JVC with this setting on is ok. For other tapes, experiment yourself, because these is a significant difference in the final image (I generally use B.E.S.T. on) |

The attached pictures are with D3R off. I think the On versions are better (for this tape), idk. What do you think? I will test this setting more by using diffrent tapes. AviSynth is an unknown world for me. Tbh, I don't know yet how to reduce the size of the raw file and do restoration etc. Should I check AviSynth or should I find something else? Thank you. |

While there to save a specific frame ad image, "Video -> Copy source frame to clipboard" and past the image in Microsoft Paint, saving from here as png. For the middle image the setting D3R off is better https://imgsli.com/MTM2NTY0 Fot the other 2 I do not know thow to evaluate because the frames features different patterns (may be not at the same moment in time?) https://imgsli.com/MTM2NTYz https://imgsli.com/MTM2NTY1 If you do not plan any restoration (except removing head switching noise), with this tape I think is better to used "norm" and "D3R" on. The size of the captured file can be reduced with a compression using h264 codec through a basic command line: Code:
ffmpeg.exe -i <input.avi> -c:v libx264 -crf 17 -preset slow -aspect 4:3 -c:a aac -b:a 128k <output.mp4> Code:
ffmpeg.exe -i <input.avi> -c:v libx264 -crf 17 -preset slow -aspect 4:3 -x264opts interlaced:tff=1 -c:a aac -b:a 128k <output.mp4> Entering in AviSynth you will open a new world. There is nothing similar except VapourSynth. Other tools like NLEs and Upscalers may be used with AviSynth to perform specific actions (color correction, upscale, ...) |

I'll check 2-3 tapes more these days. I'll post the differences between on/off. Hoping it'll be more helpful. Quote:

My plan is to reduce the size without significant quality loss, for some tapes I would like to keep the audio raw, crop the head switching noise (hoping to keep the right ration xD) and maybe some color correction if needed. I can't think something else rn. About interlaced/deinterlaced video I'm not sure what should I do, tbh. I always deinterlace my videos but is that the right thing to do? I wish I could upscale some of my videos but I don't think my pc can handle that waiting days/months to finish a single video xD I guess I can do all these by using AviSynth but I don't know how. I'm beginner so I need to read a lot I guess. I don't know If I'll find the right guides to help me. Or else I'll get away with command lines or handbrake. Idk. |

If you want to use the latest algorithm in VapourSynth (ESRGAN, BasicVSR, SwinIT...) it will be much more complicated, but that's another story. |

Btw, how can I extract the Raw audio, If I want to? I tried File->Export->Raw Audio but I'm getting a .bit extension. :hmm: I also tried File->Save WAV and it seems legit. But is it the right way to extract raw audio? If I want to get just the audio from a tape, all these settings (Picture control, D3R, B.E.S.T etc) doesn't affect the audio, right? Thanks :) |
Wait a moment.
Your captures suffer of an ugly vertical jitter. That's the reason of the jagged lines. Either the even or the even field is often shifted. You can check yourself with this AviSynth script; open it in VirtualDub and move frame by frame: Code:
video_dir=".\" There is no simple way to solve this (common) problem, because I assume the lineTBC of your JVC is on. You can try another tape in better conditions (to limit the problem to this specific tape), or a different VCR, or disable the lineTBC of your VCR and add a Panasonic DVD-R ES10/ES10 having a stronger lineTBC correction. If the shifted fields are just a few, they can be corrected in AviSynth (I wrote some post about it), but it is not your case :( edit: now you understand why is better to provide a sample of the capture, an image alone does not say much |

Can I, at least, keep the audio from this tape? Or should I try something else (just for the audio I mean)? Idk. I capture the whole tape some days ago using the settings as shown in the 1st post. Thanks for helping me out. I really appreciate it! |
TBC should be always on. For this tape it is having a difficult time stabilizing the frames (fields), and introduces fields-shift. Across multiple captures the defect is generally present at the same frame, sometimes it is not. But you have too many to rely on this opportunity.
Audio is not affected by the video glitch. |

My impressions at first and quick analysis:
"me" videos https://imgsli.com/MTM4MzY3 pc=edit_d3r=off_best=off versus pc=edit_d3r=off_best=on -> no winner https://imgsli.com/MTM4MzY5 pc=edit_d3r=off_best=off versus pc=edit_d3r=on_best=on -> winner pc=edit_d3r=on_best=on https://imgsli.com/MTM4Mzcw pc=edit_d3r=off_best=on versus pc=edit_d3r=on_best=on -> clear winner pc=edit_d3r=on_best=on overall winner pc=edit_d3r=on_best=on "po" videos https://imgsli.com/MTM4Mzcx pc=edit_d3r=off_best=off versus pc=edit_d3r=off_best=on -> no winner https://imgsli.com/MTM4Mzcy pc=edit_d3r=off_best=off versus pc=edit_d3r=on_best=on -> winner pc=edit_d3r=on_best=on https://imgsli.com/MTM4Mzc0 pc=edit_d3r=off_best=on versus pc=edit_d3r=on_best=on -> clear winner pc=edit_d3r=on_best=on overall winner pc=edit_d3r=on_best=on To my taste the best setting for these 2 tapes is pc=edit_d3r=on_best=on, which is not the setting I generally use, but in your case is what I prefer. YMMV. Looking to the videos instead of the fixed images the impressions are the same. This is the script I used, you can check yourself the comparison for the future. Good luck with your captures. Code:
v1=AviSource("VHS/me_pc=edit_d3r=off_best=off.00.avi").subtitle("me_pc=edit_d3r=off_best=off.00",size=20,align=2) |
I have that VCR, best settings for me are:
B.E.S.T. : OFF PICTURE CONTROL: AUTO O.S.D. : OFF DIGITAL 3R: OFF DIGITAL TBC/NR: ON (GREEN LED ON BUTTON) |

Now, I have to see what to do next with the files (edit etc.). I'll check AviSynth first... :hypno: Quote:
