I need to purchase a device to digitize a bunch of VHS tapes. After I do so, I'd like to use the same device to send a composite (yellow plug) video signal out of my camera into mimoLive. I'd welcome advice on which product to buy. Thanks!
Some years ago I used a simple Video to USB converter for this task. I didn't worry much about the quality because PAL (or NTSC) is a poor quality anyways ;-) I think any convert will do which is compatible with macOS because those devices reports to the system to be a webcam and those are all working in macOS and therefore in mimoLive as well.
Do your camera only have a NTSC/PAL out? I am wondering because this signal is analog and poor quality compared to a digital signal. So your cam will capture in digital, converting to analog, then the Video to USB will convert it back to digital. On this path you are loosing lot of image information. If your cam has a digital out I would rather use this.
The blackmagic design intensity range can be used for this. I have an Intensity Pro in a Sonnet enclosure. I have been converting tapes from an old Sony camcorder that outputs via composite. The Intensity card has a breakout cable that includes a composite input.
Achim is right about the analog -> digital conversion. The captured video shows up all the flaws from the video tapes. It's made worse by the fact that PAL is such a low resolution and these days our screens etc are such high resolution.
I have the Sony Z7U cameras, which have HDMI, Firewire, component, and composite out. Previously I used firewire to connect the cameras, but cable length and processor delay were issues. HDMI works fine for most uses, but when I have need for longer runs, I thought I could use the composite signal into whatever I buy to convert the VHS tapes.
