Color Correction – HD on SD timeline
Hi there,
Been meaning to get the Matrox MXO to color correct on my calibrated NTSC monitor. Problem is the MXO won’t play 24p (or so they say). But here’s the thing, trying to say a few coins, so was wondering the following: What if I cut my timeline (DVCPRO HD – 720p24) and pasted it on a DV50 timeline and output to my monitor simply for color referance, then applied those same filters to the corilating clips on the DVCPRO HD – 720p24 timeline. Is this a possible work-around for the time being.

FCP should add the appropriate pulldown to get you to 720p60 for the cc. Matrox should support 720p60. They probably don’t support 1080p24 is what they should say.

You won’t get the true range of HD colors if you CC on an SD monitor or in an SD timeline. Especially when you get into reds which you can push much further in HD than SD. If you’re working in and delivering HD, you need to CC in HD.

I will deliver in SD DVD, so I’m concerend with the 7.5 IRE issues, so not sure what my options are?

If you’re doing an authored DVD for SD only then you’re fine to CC in the SD timeline and just finish out from there.

If you shot digital, keep the ire @ 0. DVD is digital, keep the ire @ 0. Hopefully the DVD player will add setup on analog outputs, if not and the video is going digital, your ire should still be 0.
And I second what walter says about the cc.

Well I’ve had so many issues in the past going from DV25 to to DVD. I’m very glad to be out of DV25, and this HD image is really looking robust, hate to lose everything going to DVD. I did finaly get good settingswith dv25 going bitvice and a plethora of other hocus-pocus. And now with the new compressor, not sure where to begin in finding the right compression settings once I do color correct. Perhaps hiring someone with a hardware encoder is the answer for the master DVD’s. But if I do that, is it best to keep on HD timeline. Or, if as Walter suggested, output from SD timeline, do I go with DV50 or perhaps a photo JPEG timeline. Any thoughts?

This is what I do and it works for us. If we shot HD and need SD DVDs, I cc for HD for an HD master, and then I CC watching the downconverted SD (with a duplicated HD timeline of my CC’d HD timeline) and then I make the DVD from that using compressor. Compressor does a pretty good job for our needs, but I definitely do not go with the default settings. A hardware encoder is not really necessary for us. DVDs are our review copies for clients, we then master to tape…usually.
That’s my suggestion, I’m sure other people will have others.

Thank you for that info. What are your steps in downcoverting to SD. I’ve read numerous methods. Wondering what works best for you and what are some of the main settings you change in compressor to compensate for your downconversion. I never use defalt settings in compressor, but I often end up tweaking forever. If you have any tidbits to steer me in the right direction, it would be most appreciated.
All the best,

I film in DVCam and CC in a DV time-line, but when I’m about to export to Compressor to make the MPG2, I set the sequence in 8b Uncompress. If you keep in DV before to go to Compressor your waisting 75% of what you have get with the CC.

This honestly makes no sense to me. If you’re going to move to an uncompressed timeline, then do it BEFORE you color correct. Color correction is different in a DV timeline than an uncompressed timeline, again using Red as an example. It falls apart even faster in a DV timeline than an Uncompressed timeline.
Uncompressed is 4:2:2 and DV is 4:1:1 so you’re not getting the full benefit of the uncompressed 4:2:2 color if you CC in a 4:1:1 timeline. You’ll get a much better color mix if you work in the 4:2:2 color space.
