FCP Video Scopes won’t work
I have on-lined a sequence (10 bit PAL standard def from HD CAM tape) The problem is my Video Scopes won’t play in real time. They only refresh when I pause. So when I apply a colour correction to a clip and move the black/mid/whites sliders they don’t show in real time either.
And when I load the video into the viewer it appears darker than the sequence; it brightens when I play and the darkens when I stop. When I apply a colour filter to the clip in the sequence it shows as unrendered when playing which I expect, but is darkened in pause.
The AV Settings for the Sequence is set to Blackmagic PAL 10Bit, video playback is Blackmagic PAL – 10bit (720×576). My RT is set to Full Quality and All Lines

The Card is a Blackmagic Decklink Extreem (Standard Def).Any suggestions welcome.

Hi Neal,
Not sure if the problem is on the VideoScope, or on the footage your are editing.
What kind of media HD are you using?
Your RT setting are making things harder too.

The source media is from a HD CAM (a Sony 730s HD CAM) so it’s Pal 50i. But it’s captured as standard def through the Decks SD SDI output. So I’m not onlining HD but SD in 10 bit uncompressed.

Make sure you have your scopes open and a sequence in the timeline.
In the realtime popup menu in the timeline choose “Video Scopes Playback.”this will require additional processing power, but this should solve your issue.

Hi Kevin,
When I make an online project the menu I don’t get a “Video Scopes Playback” option in the RT menu on the timeline. In an off-line project I do (I use PAL DV for offline).
Rafael, I just tried a new project (PAL SD 10bit) with no captured media and made a sequence with SD PAL bars and text, so all generated internally and the same issue occurs with the darkening, no scope and the RT Menu not giving the “Video Scopes Playback” option. So it’s not the footage.
Could it be the decklink card? The system says all software is up to date. The media drives are fine and the hard disk is ok, (just ran disk warrior.
I’m on FCP Version 6.0.6

Kevin suggestion makes a lot of sense.
About your Gamma issues, BlackMagic 10b is a legacy codec. Was replaced (togethere with AJA 10b/Unc) by Apple 10b Unc long ago.
If is available is to allow to play old BM stuff.

Neal, do you have your video scopes open also? That option will not appear unless the scopes are open.

I’ve experienced EXACTLY what Neal is experiencing – no realtime scope readouts and the play/pause luma changes.
I was working with 4:4:4 RGB footage and my color space/bit depth settings weren’t set right for what I had in the timeline.
Go to sequence settings and then the tab for video processing. Change your render settings there. That’s what fixed it for me. I hope that fixes it for you.

Hi Chad,
I have played around with my Sequence settings and find that if I set the sequence to Apple Prores 422 scopes work, (with Video Processing set 10-Bit high precision YUV). That’s even though the footage was captured as Blackmagic 10 bit unc. Kevin this setting gives me back the ‘video scopes playback’ option in the RT menu.
So between Kevin, Rafeal and Chad and we have a solution, cheers guys, I owe you all a pint so if your ever in Ireland…
A last question: should I capture in Unc 10 Bit 422 and avoid the Blackmagic 10 bit option an set my seq to Apple Prores 422? I thought that Apple Prores 422 was only for HD footage? The question is will this produce a technically sound picture on digibeta (SD)? Don’t want a broadcaster tekkie giving me grief when he does a quality control check on a master tape.

No reason for not using Prores for SD. Is a codec designed to replace (?) 10b Unc codecs: Very high fidelity and multi-generation without degradation, and manageable files.
Another advantage is that can play on any PC just with QT for Windows.
Since his release has become the “de facto” 10b standard for people working on Mac.

Good news Neal!
Thanks for posting back that your problem was solved. It’s frustrating sometimes when we all try to help each other on the COW and then people never follow up…Then none of us know if the posted solution worked, or if it was wrong, or what the real fix was, etc.So, let’s get back to real business….that pint you mentioned.
