I'd like to get a proper video capture card, but my PC is too old and archaic, not to mention there are no PCIe slots available. Also, they are too overbudget for me at the moment. (Perhaps someday in the future, when I hope to upgrade to a fine machine... and redo some of the captures (not all) and, of course, if my VCRs still work by then. )

I thought of something like those pen-drives that capture video just like you mentioned, but after my experience with a MAGIX one (poor quality), I wasn't sure about ElGato's similar options. And they were still more expensive than this 129€ Avermedia.

I also have plans to record videogames for Youtube purposes, so that might have also influenced my decision.

I believe it's Top Field First, but I can't tell for sure.

I live in Portugal, so all my recordings are PAL.

EDIT: I just realized I never uploaded the new video sample of the VHS tape in case. Here it is:

Something like this and then either duplicate or interpolate the frames to get to 25p?

sourcefile = 'G:/Vapoursynth/vid.mkv'
c = core.ffms2.Source(sourcefile)

c = core.std.SeparateFields(c, tff=True)
c = haf.srestore(c,frate=25)
c = core.std.DoubleWeave(c, tff=True)[::2]
c = hnw.QTGMC(c, TFF=True, Preset="Very Slow")
c = c[::2]

Guys, I've just realized something: I messed up. This is not my original thread regarding VHS capture with an Avermedia capture device, this is:


I'm terribly sorry about this confusion. I guess I should migrate my newer posts there in order to do some damage control.
