Sometimes you don't want to have a computer involved while recording.

  • Machines are currently pretty much free to get started with
  • Records to VHS tapes
  • Tapes are cheap

Rescan

The art of pointing a camera at a screen

First rescan tests

  • This is a playlist trying out rescanning at different resolutions (480,720,1080,4k)

4k Rescan playlist

this video discusses some of the points you’ll need to address when rescanning a CRT

  • Things of Note – set camera to 1/60 (NTSC) / 1/50 (PAL) shutter speed – turn off lights in room and/or utilize/make a monitor hood – adjust back light on monitor if possible otherwise adjust brightness/iso until a desirable image is found. – on my camera in a dark room an iso of 100/200 is necessary for rescanning

Cameras used for rescan:

I’m using a mevo plus (only because the place I work for bought one and it isn’t getting used currently) I would not really recommend this camera unless you understand how it works as it is weird… that being said a newer version has been released so this version is fairly cheap on ebay now.

Details:

In order to get a useable input into the hyperdeck shuttle from the LZX visual cortex component output use the Extron 300a to get the video into the YUV colorspace.
