I'm trying to digitize a bunch of old VHS tapes, with a JVC DR-MV5s combo deck.

I have been experimenting with different settings and digitization options.

First attempted technique - Use the auto-dub feature to convert 1 VHS to 1 DVD, then copy the dvd to computer.

This was simple and straightforward enough, but I soon realized it wasn't recording in the highest quality settings

Second attempted technique - dub to DVD in XP quality mode

The quality was visibly much better, but it can only fit an hour of VHS footage on to a DVD. Many of my tapes are 2:30+hr long, and the additional effort of creating 3 DVDs for each VHS, then transferring to a computer to edit and stitch together didn't seem worth the hassle.

I decided to purchase a easyday DC60 USB capture device, so I could capture the entirety of the VHS in one shot, and also avoid needing to copy several DVDs over to the computer. I'm trying to do this archiving with the existing equipment I have, but $10 for a USB capture device seemed cheap enough to be worth a shot.

Third attempt technique - USB capture device

I've tried at least a dozen different methods of using the USB capture device. I've used the included software with the device for capturing; I've used VLC to capture from the device; I've used VirtualDub and OBS to capture from the device, etc.

Every time I felt like I was making improvements to my technique using the USB capture device, I would compare it to the XP direct-to-dvd dubs from the JVC and the direct-to-dvd dubs always appeared better.

After all these tests I was hoping that a 175 GB raw AVI captured in VirtualDub @ 720x480 in YUYV would look better, but it just wasn't the case.

Does the DR-MV5s has built in TBC or filtering functionality that gets applied when digitizing VHS tapes to DVD, but does not get applied to the composite video-out?

And the unlikely-to-be-possible question: If the JVCs internal digitizing capabilities are superior, is there a way to modify the machine so the processed digital signal (that would normally be written to a DVD) is sent to a HDD/serial/USB/etc.
I.E. a way to get the cleaned up signal onto my computer, without having to deal with DVDs at all?



I'm getting anxious to start this project, as it's been several months of experimentation; but I'm reluctant to pull the trigger until I am relatively confident that I have the best workflow established.

Judging by the manual it does not apply to the video outputs. It does seem to have a "progressive VCR output" mode on the component output though, which will have to go through some digitizing step. That would require capture card with component inputs, and you would get a deinterlaced (possibly 60fps) video signal. I doubt there is any other way unless one is an electronic whiz that would be able to tap chip outputs or something.

You would otherwise need some better gear as discussed in a million threads.

No idea if it does anything on pass-through like some DVD-recorders if you hook it up to a different vcr either.

Thank you so much for informing me of this. I had no idea it had this functionality, and, after some testing, it definitely results in the best quality I've gotten when playing back VHS on a TV. The labeling on the back of the JVC made me think the component out was strictly for DVD playback. (I had even tried it, to no avail, not realizing that there were settings that could enable component output for VHS)



Capturing the component stream definitely seems like the best way to utilize the JVC, so I bought this: Blackmagic Design Intensity Pro - HDMI and Analog Editing Card

Unfortunately I haven't had any luck getting it to work on my 64 bit Win10 computer. Is this a good card for component capture? Should I keep trying to troubleshoot it, or are there more reliable devices that can capture component (ideally something that works with Virtual Dub). I have enough hardware sitting around that I can build a dedicated compouter with whatever version of windows would work best with whatever capture device I end up using.

I had read in this post that component capture wasn't too popular. Is this just because many VCRs don't output component for VHS playback?

Yeah VCRs don't typically output component as it would require extra hardware to change the colour signal from a tape into a component format and don't really anything over S-Video for normal SD playback. It's similar to RGB signals, just with Y Cb Cr channels instear of red green blue. One interesting quirk about it is that component doesn't properly support macrovision, so it's an option when recording signals passed through a DVD-recorder.

You only really see it on DVD-recorder combos as they already contain stuff to digitize the video signal. The output you are getting is going to be de-interlaced though (as it's "progressive mode"). I don't know how good the deinterlacer in the VCR is, but it won't be as good as say deinterlacing with avisynth/QTGMC in post. Also not sure if it will output 30 or 60 fps.

The blackmagic cards should work ok on Win10, they are modern cards after all. What issues are you having?

I don't think there is going to be much noticeable quality difference between capture cards for component.
