QMaster is on, and according to iStats has been using all 8 cores, at full wack, for over eight hours. ETA is now predicted as 29 hours …

Hey Jeremy

Your suggestion worked!

Many thanks for taking the trouble to respond

I have just encountered this same problem, and I AM using Screenflow (1.5.2). Never had this problem before, and I’m in a panic as I’ve got a deadline in a couple of hours and I’ve been up throughout the night!

I imported about a dozen such clips and about half of them are ok, but the rest are now 10fps within FCP, but still 25fps on the original QT files.

Help!

[Harry Powell]

Adjusting the sliders does improve things, by making the effect more more diffuse but I can’t seem to clear it fully.

Bit nervous to delete preferences right now in middle of impossible deadline (particularly as FCP Rescue 6 link seems broken – and I think there are reports that it doesn’t work with Leopard?). But I’ll give it a go when I can.

Thanks for your replies.

[Rafael Macho] “Thank you for this link, it answers my problem.
I also realized that DVDSP can’t author Blu-ray, which is really surprising. I tried to keep working with Final Cut Pro Studio, but I think Apple is getting behind. I’ll give a try with Encore CS4, which I never used until now.”

Glad it was helpful, but curious about your conclusion? The link explains how to do it with FCP7 so why do you need to use Encore CS4?

[Harry Powell]

Haven’t tried it myself but according to this article, you can burn high definition video onto standard DVD-R discs (using the mac’s super-drive) that playback in a Blu-ray player (such as PS3).

Let us know how you get on as I may need to do something similar in the future

[Harry Powell]

Thanks for the replies. I’m not too experienced with keying/masking etc so apologies for ignorance.. (and for being too chicken to go into Color right now!)

I used CC3W and isolated the white, i.e. everything is black except the white.

I applied it to a copy of the shot (above untouched original in timeline).

I wasn’t sure how to ‘mask’, but through trial and error I tried right-clicking top clip and chose composite mode, then subtract.

Is this what you meant by masking? It was rough but perhaps I should tweak more?

The other big problem was that once I rendered the filter effect it went black all over, i.e. blocking clip below also.. Why is that?

Thanks

Thanks Dan for your very informative and comprehensive response. And I have read the link you provided and all the comments as well! Mind-blowing indeed.

I’ll certainly need to purchase a broadcast monitor if I’m doing broadcast work (or go to an external facility for grading). The current project is for web use (and occasional screenings at ‘conferences’) and they want a High Definition H264 QT movie file for both these purposes.

If I am not mistaken, the QT preference enabling ‘FCP color compatibility’ (although helpful to me) is not available (and/or not familiar) to all with QT (even if it is the newest QT).

And I believe, it’s not just a gamma shift but also a green shift as experienced by this poster:

It’s been suggested that converting to Motion JPEG (100% quality) then to H264 resolves the problem – but perhaps I’m getting confused with the more subtle H264 shift? In any case can’t seem to find Motion JPEG in the list of codecs, and it didn’t work with Photo JPEG.

And there was a solution suggested involving changing transparency settings in Movie Properties which didn’t work for me.

Here are 2 screen grabs I did showing the big difference, for when the QT preference is on and off (perhaps not ideal for showing the green shift as the walls are green):

I hope it shows how awful it would be if someone online, (or at a meeting with TV playback from their laptop), on PC or Mac, sees the washed out version. Surely there is foolproof solution (when QT is the delivery format) to this?

Thank you again
Harry

p.s. I’m on Leopard, on an (early 2008) 8-core Mac Pro with an ATI Radeon HD2600 graphics card.

[Harry Powell]

Thanks from me too!

Would be nice to hear from anyone else who can reaffirm your experience.. before I rush out and buy a new graphics card(?)

Using FCP 6.0.6 and have an ATI Radeon HD2600 in an 8-core 2008 Mac Pro (Leopard). Would any non-ATI card definitely solve the gamma problem I wonder? Any recommendations?

I have been trying to find a solution for a long time and many threads with different ideas end inconclusively, and/or their suggestions haven’t worked for me.

I’m also getting more than a simple gamma shift, as described by Chris Wiegand here https://forums.creativecow.net/thread/8/982913#982913
i.e. I’m getting some extra green too!

And must admit, even the basics are confusing me. For example (maybe slightly off topic), when using ‘Display Calibrator Assistant’ – it first instructs me to push contrast to maximum setting. Am I meant to leave it this way after calibration is finished? Also, the 1.8/2.2 gamma settings option comes up as one of the final steps. Surely this should come up near the start, before you do all that manual fine tunings? I just don’t get it. And which gamma setting should it be for FCS work anyway? Would it be the same for DVD authoring and web work?

[Harry Powell]

Thanks everyone for your help. I went with applying a TC reader filter to the clips in the end, and customised the label (i.e. first part) of the TC for each clip to reflect the source AVCHD media. I had feared that this would create rendering/playback delays, but it all worked in real time thankfully.

To be honest I haven’t had a chance to properly try the nesting method but I will when I get the chance.

One thing that really surprised me prior to doing the above, is that TC generated by Compressor cannot be taken from the source clip TC. Or perhaps I’m missing something? Surely this would be a useful option?
