VHS Software displays black lines, splitting video
2 Attachment(s)
I am trying to digitize a VHS into my computer but ran into a cropping problem (image 1, blue screen with black lines). I don't know if this is caused by the software or by the VHS player itself, but I have tried multiple different Softwares that show the same thing.
I have recorded a part of the VHS tape and fixed the video as far as I could, which is how I got image 2 (image 2, zooming in on some grass with black lines). I want it to show me everything in one place, like a normal picture. Sharp VC-H960 VHS connected to a Windows 10 Professional I apologize for any duplication from any other thread...I just can't find an answer. |
How do you have the VCR connected to the capture device? Remove any extraneous cables. Connect composite (RCA) yellow output from VCR to composite input of your capture device.
What you're seeing is the video offset vertically and horizontally, exposing the non-image areas of the video signal that are normally hidden ("vertical & horizontal sync / blanking"). Related thread: http://www.digitalfaq.com/forum/vide...rent-bars.html Please attach a 10-second (or even 5-second) video showing the issue as well. You can compress it with a low bitrate; the quality doesn't matter. I'm assuming that the image is rolling in the down-right direction. What is the capture device? You mentioned the VCR and the operating system but not the capture hardware. |
Found the solution
I found the solution:
Some software doesn't read the USB the correct way. I found software that makes the image as I want it. Sorry for bothering you. |
That's extremely vague. Please provide more information, in case someone else has the same problem in the future.
What is the hardware and how did you fix the problem? Quote:

Different software
Some software uses different techniques (drivers, I guess).
DScaler, for example, made the splitting lines and put the video parts in different parts of the screen. Movavi showed the picture like normal. Most of the software I used most likely used drivers similar to DScalers. Movavi used a different one. But that's my guess. Also, I have no idea what hardware the USB is using or what. |
Did you try Vdub?

And here is one way to grab hardware IDs:
|
USB\VID_534D&PID_0021&REV_0121&MI_02
USB\VID_534D&PID_0021&MI_02 The thing is I just found this device and has nothing written on it so I have no idea where it came from or what it's called. The name of it that shows up in Device Manager is "USB2.0 MIC" |
MP4 sample: many problems! Let's solve them.

^ lol, what do you mean you just found it? On the ground? :D
Those USB IDs indicate it's the most common EasyCAP (EasyCRAP) out there; the EasyCap DC60 (Syntek STK1160 chip). I compared its quality using test patterns here. Note: I requested a sample of the now-working capture, because I'm considering buying this VCR model locally and I'd like to get a rough idea of how my tapes may look played through it. The OP was kind enough to provide a 7-second MP4. VCR Sharp VC-H960 = VC-H960U is a (North) American machine, NTSC format. There is no PAL variant with this part # scheme. The sample MP4's MediaInfo Code:
General It's 640x480 @ 50fps, encoded in progressive mode. This is a mix of standards, and should never happen. You should capture 720x480 @ 29.97fps, then if desired* deinterlace to 59.94fps (double-frame-rate deinterlacing, aka "bobbing"). The MP4 sample is missing half the temporal information; the underlying frame rate is actually 30fps, with duplicates added to bring it up to 50fps. I've attached a sample where I used the filter TDecimate with option Display = True and then re-compressed with x264. The Display option shows where the duplicate frames were detected and removed. They have metrics ~0.3. Metrics for duplicates are typically <0.5 depending on noise level of source, in my experience. Short Avisynth script: Code:
# Load video clip, with audio The saturation of this clip is also extremely low. Meaning: it's almost black-and-white. Maybe that's just how the camcorder recorded in this low-light situation. I would appreciate it if you can attach a 720x480 @ 29.97fps clip of a TV recording or movie using this VCR (30 seconds or less, if in MP4 format). Let me again say thank you for sticking around. I was really worried you'd be a 2-hit wonder.

I didn't include the lossless.
Like, legitimately, just some software uses different drivers than others. Some drivers can read properly and some drivers split the video and make it weird and very distracting. |
