How to capture VHS generation loss? With no low frame rates?
1 Attachment(s)
With a forum dedicated to achieving the highest quality of video from a VCR using a capture device, it may come up as weird that someone would want to intentionally degrade the video signal and try to capture it. Nevertheless, that is what I am trying to achieve which is trying to capture VHS generation loss (copying a VHS tape onto another VHS tape and repeating the process, here is a video on how it looks like for this who do not know what it is https://youtu.be/BoAHQM9coU8). Now to the equipment I use to do this is a
Now the uploader of that video mentions he uses
Try to correct the horrible video signal produced by the copying process of a VHS tape onto another? or Will it leave the tracking errors as is and just make sure the video does not drop in frame rate from the TBC to the capturing device? (Essentially I want to achieve leaving as much mess of tracking errors, if you will, whilst also not having low frame rates) Another thing I would want to add is that the person who uses two Sony VCRs and does not appear to use a TBC nor could I find those VCRs having a built in TBC (I could be wrong on this). Is it that it just outputs a better signal compared to the Toshiba and Orion VCRs that I have? Or is the capturing device that he uses better than the Pinnacle 510 that I currently have? |

In order to do a good job of degrading, you need to understand the fundamentals of what causes noise. While most here will want to use that knowledge to correct the video, I see no reason why an artistic project using the same basic knowledge is any less valid. I've simulated errors before, to illustrate issues. Same concept. Quote:
And yet, I've seen similar nth gen tapes for decades. Unwatchable, cannot be restored. Quote:
Frame sync TBCs correct the signal, not the visuals. What you're seeing is not something a TBC will fix. In fact, a TBC can make awful nth gen timing errors worse. Frame TBCs allow snow to be recorded with no dropped frames. Certain errors cause skew and line loss on the first image lines of the image. TBCs sometimes rebuild those well enough that the mild jitter goes away. Line TBCs usually make those worse, get confused. Tearing is a pervasive error that can be fixed with field TBCs, or a strong line like ES10/15 (which is also crippled). I think a true frame TBC will correct what you want, and NOT correct what you don't want. I wish TBCs did more, and you want them to do less. Ironic. But we both know the limitations of the device, and use it as needed for our projects, different/opposite as they may be. Quote:

Also I do not know if you are aware of this method (most likely are). But there are some people who instead of using a analog to digital capture device like a lot of people do here, they use a AV to HDMI converter and then a game capture card (captures of an hdmi signal essentially). A popular one I did notice was the Elgato capture card. Essentially its the same process but they convert it to hdmi before they capture it. (Like this fellow right here However, it doesn't seem like it is a preferable method but I could be wrong. |
