    Need Help Recording a CRT Monitor
    #1
    Default
    Hi all, I am going to be making some videos in which a 15Khz CRT monitor is the main subject and I can't figure out a way to record clean video without flickering/banding on the display. Any tips on what my settings should be? I do have Magic Lantern installed.

    Whenever I'm confronted with this problem I just use a camera that has "Clear Scan" or an "ECS" function as Sony calls it and just keep adjusting the shutter speed using the Clear Scan/ECS switch or scroll menu until the flicker / rolling frequency bar is dialed out. If you are using a DSLR I think you are not going to be able to overcome the problem easily. Sony brought out Clear Scan/ECS on a range of their cameras for the specific reason of shooting CRTs. Alternatively you could possibly hire a Sony DSC-1024 Converter that can go into the monitor line before the monitor as it can put out a recordable video signal of what is seen on the CRT.

    Do you mean the monitor is visible in the image, incidentally or you'll be framing a full screen?

    I will be framing a full screen taking video of some retro gaming on the monitor to show off the scan lines and such. I want to get close up with a macro lens as well as take wider shots where the entire monitor can be seen. This is a quick test I shot while testing different settings and it is the best I could do. I believe it was 60P and 1/60 shutter speed.

    Thanks Chris, that is unfortunate. Do you know of any budget cameras that have this feature?

    Just wanted to say that I was able to adjust the shutter through Magic Lantern to perfectly match the fresh rate of the CRT and I've got what I needed. Thanks.

    It's great stuff for sure. Wish it was available for the 5D Mark IV. I had to go out and buy a used Rebel just for ML.

    Really! That's great. I'm not really familiar with ML so it's good to know this adjustment capability is available within ML. Problem solved by the sounds off it!

    They just made some progress with the 5D Mark IV a few days ago...but probably a few months away to anything usable (if possible).
