View Full Version : CRT monitor for color correction
Raymond Jebb January 7th, 2010, 07:22 PM Just hooked up the monitor and it works! What a relief. But I can only see picture from my camera, either in play or VTR mode, but I can't figure out how to send image from Final Cut. I thought I could select the monitor from VIEW> then either VIDEO PLAYBACK or EXTERNAL VIDEO, but I don't think I can do it from there. Can anyone help? Sorry
Raymond Jebb January 7th, 2010, 07:35 PM I just saw some options in my Final Cut.

I am selecting NTSC and the picture quality seems really very low. Seems very interlaced, a bit blocky (not sue if this is a correct expression) - quite pixelated... Am I doing something wrong?
Also, it seems that as soon as I select the monitor my big LCD (DIGITAL CINEMA DESKTOP PREVIEW) doesn't show the preview anymore. So it's either the CRT monitor or I have to switch back to the LCD and loose the CRT. Is that how it works?
On my Canon HV20 I selected 480i component out.
P.S. Just tried to play back form timeline and the play back is not possible. It's like a freeze frame on the CRT monitor, even though the timeline keeps playing (very very choppy) and the image doesn't change...
Craig Parkes January 7th, 2010, 09:13 PM It's probably because you have chosen DVCPRO, you should chose FIREWIRE NTSC, your Canon cannot display DVCPRO signals
That should exhibit correct playback qualities, ASSUMING you are on a DV NTSC encoded timeline.
As far as I know you can't monitor your footage out of the camera in HD, as it will only accept a firewire DV NTSC signal across the output. If you set up your machine so that it playbacks on DV NTSC I am not 100% sure whether you will have to be working on an SD/DV native timeline to be able to get realtime playback in Final Cut.
Also, yes, you can only EITHER Digital Cinema Desktop Preview or monitor through an external source, you can't do both at the same time.

Hi Craig, my timeline is HD, 720P and 1080P. Probably that's why. I only selected DVCPRO after I had a problem with regular DV NTSC. So it's the same situation across all options. Honestly, I don't care if I can't play back in real time my footage, but at least if I can get real colors on one frame at at time that's OK for me. But, with the image being so blocky and pixelated and also interlaced looking I'm not sure if I'm even getting a good image...
I wonder if Perrone was CC-ing HD timeline when he said that he has a CRT monitor connected to a deck for color correction?
Raymond Jebb January 7th, 2010, 10:55 PM If i put the camera in the REC mode, it shows a really nice quality picture, huge differnce between what's coming from FINAL CUT and what the camera sees in REC mode.
Perrone Ford January 7th, 2010, 10:56 PM I wonder if Perrone was CC-ing HD timeline when he said that he has a CRT monitor connected to a deck for color correction?
Yep, I was. Firewire from computer to deck. Component / S-Video from deck to monitor.
Raymond Jebb January 7th, 2010, 11:04 PM And you don't have a problem with playback Perrone? Maybe, because you have a deck?

I'm not on a Mac.
Craig Parkes January 7th, 2010, 11:20 PM I know After Effects/Premiere handles this differently, as in After Effects I know you can choose to output to DV from non SD timelines, haven't used premiere for this sort of thing... Other editors like Vegas might somehow work around this (doing a realtime software output?)
What sort of quality do you get when working on a new sequence, with DV footage on a DV timeline.
Getting that working would be the first step, as that should definitely work.

Hi Craig, I haven't worked with regular DV footage. I don't think I have DV. I can shoot some regular DV footage on HV20 and see how it works. Thanks for the tip about After Effetcs.
Raymond Jebb January 8th, 2010, 06:25 PM Sorry to keep coming back with all my troubles again.
I set up a DV timeline, 640x480 clips and the image resolution is much better the from the HD timeline. But when I scrub the timeline the image stays frozen on the CRT monitor, it doesn't move along. When I pause the timeline then the image in CRT updates/changes according to where it is in the timeline. Now, with this kind of "light" footage I would think that codec is not too heavy for the camera to process or for TV to play..?
But honestly, if this is acceptable I don't care I can grade according to the frame as long as the colors of that frame are acceptable.

A couple of things:
1. DV is 720x480 with a PAR of .9091. That leads me to believe that your system is trying to rescale every single frame on the fly. And likely not doing a good job of it.
2. The codec should be light enough for any modern PC to play with ease. But if it's trying to rescale it all, then that could account for your issue.
3. If you are willing to grade this way, that's fine, but does the TV image update if you change the colors?
Raymond Jebb January 8th, 2010, 08:36 PM Hi Perrone, yes it does update the colors!
Raymond Jebb January 8th, 2010, 08:42 PM Perrone, I can't believe!!! You're absolutely right. Thank you soooooo much!!!! I converted one of my clips using MPEG Streamclip and gave it a correct NTSC setting and it plays like charm!
I can't believe I didn't try this before and kept bugging all of you here :)))
Thank you again

Ah, the light bulb moment...
Now, the trick is to see if you can create an HD file, use the correct project properties, and get THAT to play smoothly. both 1920x1080 and 1280x720 are PAR 1.00. So give that a try and see if it plays smoothly.
