So following the good advice I've received previously here and after reading various posts and guides this is the setup I've ended up with.
VCR - JVC S8600
Hi8 VCR - Sony EV-C500E
(and a couple of Brighteye devices I have to use in unison)
Open Broadcast Software (OBS)
The JVC ticks the right boxes, has Dynamic Drum & Digipure TBC/NR and the vcr appears to be in good order.
The Hi8 player was bought untested and for spares but appears to play okay, although it can freeze on rewind.
The Pioneer SVM is an odd choice as a time base corrector as it's a DJ mixer. It wasn't bought for the purpose and I didn't realise it had one until I tested it. It seems to work as one okay, and really I just like the fact I can route all my SD connections into it and have one output connection from which to capture.
The XCapture-1 I purchased as I liked the flexibility it offered as an external box, lots of different input types and 60 fps.
The KWorld I bought as I liked the styling
and it cost next to nothing on eBay
I've been using OBS for all my captures previously and have been happy with the results but it can't really do lossless capture.
Following advice from here I've been playing with VirtualDub
and have Lagarith and Huffyuv
With the above out of the way, and the main reason for the post is, I can't get the XCapture box to work happily with VirtualDub.
It doesn't seem to be getting a steady signal from the box and is dropping and inserting frames. It's also messing up the audio as it's trying to keep it in sync. I know not all capture devices work with VirtualDub but I've seen online it has been used successfully with the XCapture-1.
I've tried all sorts of ways and settings to get it working stably but to no avail so if you have any ideas I'd be glad to hear them.
Ironically the KWorld appears to work fine with in VirtualDub, at least it does when audio playback is disabled. But I can't use that as a capture device on point of principle, being so much cheaper it must be inferior to the XCapture-1 right?
