VHS capture, analog noise gets into digital artifacts.

If i do VHS capture analog noise gets into digital artifact, how mather wat resolution of bitrate i choose. 1080p and 20.000 kbps and there are still artifact.
Because of that the original analog seems always better in my opinions. a bit sharper.
HDMI capture gives better results than a RCA stick, who the qaulity is terrible and picture qaulity fuzze. Think halfsize resolution of CIF 176x144.

Is there a way how i can digitalize analog sources without that Digital artifacts?

Blu-ray has nothing to do with VHS.

It is the same HDMI capture device turned analog noise in digital noise.

Do you use an upscaler between the vcr and the hdmi capture card ? May be the upscaler is the root cause of your problem.
But as stated by LordSmurf, VHS should not be captured in HD. It's content is SD and by capturing a VHS with this device you will get a 16:9 aspect ratio which is wrong (it should be a 4:3 aspect ratio).

whats a upscaler only use those scart to HDMI or RCA to HDMI boxes you can found on Aliexpress.

And 16:9 is right the source VHS material is anamorf widescreen. (16:9 dented in 4:3)

Can you post a 30 second sample here to the forum cut direct from your VHS capture so we can
get some idea of the problems

It's nominally 25 frames per second, but it's very jerky when you play it.
Looking at it frame by frame, there are a lot of duplicates, possibly dropped frames.

VHS can look a lot better than this; even those who follow the recommended route (capture in SD @ 720x576 PAL
using a lossless codec) and then de-interlaced and upscaled to 1080p would yield something cleaner than this.

Link to good post to do that?

Thanks

Hi isfor testing, research and nostalgic purposes.

@davexnet

Why in 720x576?? The source is anamorph widescreen, it seems for me more ideal to do it in 1024x576 who is a real widescreen aspect ratio.

There are some other problems, dark areas are too black. But if i increase brightness light areas gets too light/overexposed.
Also the color is not as it must be, can change some parts to right collors with tint control, but then other collors are false, blue water gets into green. terrible.
That first part in NOT in the HDMI capture stick but in the AV to HDMI converter, if i plugin directly to monitor, the dark areas are also too dark.
And collors a bit changed mostly too false collors and with and with less saturation.

Currently modern videos are too high compressed for HD on YouTube,(1080p with a bandwitch of 2000-3000 kbps) must play in 4K or get YT premium to see real HD. very bad!

VHS has better noise than Digital.

Capture lossless YUV422.

Confused. Was this clip originally from VHS ?


Since if it was there is no such thing as anamorphic widescreen.


That dongle might have upscaled from 4:3 to 16:9 adding the side-bars in the process. But that is not anamorphic.

and what is a good one in your opinion?

i have search to direct usb recorder (stand alone, no pc required but that is very expensive and also crap most times)

Google:
It's absolutely normal having duplicated (or dropped) franes with OBS, doesn't matter how powerful or fast is your PC.. since it's a realtime capture software and Its purpose is to capture frames fastest as possibile, but it will never be 100% ACCURATE and PRECISE (there are various technical reasons behind this).

no YouTube


a 16:9 picture compressed on the sides for a 4:3 frame just like on DVD 720x576 (real widescreen is 1024x576)
no black bars.

Excuse me but the rationale for your topic is to show analogue noise.

So we have to see an original recording from VHS via, assumedly, that dongle. And not something that YT has re-butchered.


And there is another recent topic that goes in to some depth as to why 720*576 is not 4:3 or even 16:9 unless a DAR flag is present (the actual topic was for a NTSC source but the principle is the same)

Use DVD-Recorder -- for example Panasonic DMR-EH57, 575, 58, 585 etc.

So OBS is *bigger* shit than I thought. Yes, you can have duplicate frames (or dropped frames) -- but only once in a while.
