2 QT (current settings) exports from exact same source, but 1 darker?

Thanks. I’ve also noticed that if I send the project directly to Compressor via FCP, it takes about 20 HOURS to compress. If I export a QT movie (no conversion) and bring THAT into Compressor, it only takes around 40 minutes. That’s a HUGE difference. Is one doing a more proper job than the other? Why does it take SO much longer sending it to Compressor directly from FCP?

Recommended is to always export self contained QT movie and go to Compressor. It means Compressor can work in the background and FCP is free.

The problem with “Send to Compressor”, is that Compressor do not use the renders all ready done on FC and render again. If you make a “Two Passes” MEPG-2, the stuff will be rendered twice, and if you make a Multipass H264, all your sequence will be rendered THREE times.
Is a real waist of time.
As Michael say, better to export a high quality master from FC and them import it to Compressor.

Thanks. I’ve noticed that if I set it to “Render all YUV in High Precision”, it won’t allow me to render in prores 422. It has to be set to RGB.

And now FCP 7 is running VERY slow. All of a sudden, it takes forever to open the app. And when I try and render, it eventually shows “General Error” and nothing’s actually been rendered. Even after a couple of hours of running. That’s never happened before. No idea why or what this means. Other question, if my original materials were in Photo-JPEG and then I switch it to Pro Res, isn’t that adding another generation of render? Or does that somehow improve the quality? Aren’t I better just Exporting as is? Will Pro Res actually improve the quality of the export at this stage?

That makes no sense.
Should be the opposite.
Prores is YUV.[Hal Masonberg] “if my original materials were in Photo-JPEG and then I switch it to Pro Res, isn’t that adding another generation of render? “
Prores is virtually uncompressed, so it won’t cause further recompression.
The main point is that you avoid the DV codec.
Try rendering in the original JPEG codec. If you have not applied effect or changes in the Motion tab, it won’t be recompression. Exporting should be fast.

Interesting. I’ve been researching and I’ve found other folks online who have had the exact same problem as me trying to render Pro Res in YUV High Precision. Won’t allow it. See here: https://discussions.apple.com/thread/2544458?start=0&tstart=0 and here: https://discussions.apple.com/thread/3438620?start=0&tstart=0
AS for JPEG, I originally rendered it that way. And there ARE effects in the motion tab. Many of them. Does that mean I shouldn’t bother rendering in Pro Res at this stage? Will it improve the image at all?
Or, and this would be time consuming, should I remove all effects, render in prores and then put effects back in?

The issues are very different.
On the first case he is getting a “Codec Not Found” error.
That’s is to expect when he is importing to FC a 3500×2500 Prores movie.
That size is not supported by FC.
In the second case he do not specify his setting, but he is also getting the same error.
Nowhere they say they are forced to render in 8bRGB.Try opening a new NTSC DV sequence, set Prores as the codec and “Render in High Precision”, then copy and paste the stuff from your first sequence.

The point is always avoid recompression. If rendering is needed will always be better to do it to a less compressed codec, and Prores is less compressed than PhotoJPEG.
The ideal would be to render to Uncompressed, but most times is not a practical solution die to the big files size. If your movie is not too long and you have no problem about storage, you can try so.

The film’s long. 1 hr, 43 mins. I also get the “Codec Not Found” though I thought I had all the prores codecs. It works at 8bit YUV. But not 10 and not high precision. FCP also eventually crashes when I try to cut and paste the film into another sequence. It takes a long time to copy and then when I go to paste, the wheel spins for an eternity and the program eventually crashes. Never had any of these problems before the past few days. I did a smaller test of the quality difference between the JPEG version and a bit of Pro Res 8 bit. It looked a bit better. Not sure if that has to do with rendering it as Pro Res, or whether that’s the 8 bit YUV versus RGB. I was able to Duplicate the JPEG Sequence (when cutting and pasting failed). That worked, but unfortunately, when I try to render it as Pro Res, it will only let me render for a while, then I get “General Error” and nothing has been rendered. I have to stop it and save it periodically to get through the entire film. If I let it go too long rendering unstopped, General Error comes up again.

The “Codec not found” doesn’t really means that you don’t have the codec installed.
Are you using any graphic from Photoshop or so?
Make sure they are RGB and not CMYK.
That is one cause the “Codec not found” error.Try something very simple that quite often fix some issues: Use the “Save aas..” function and save your project with a different name.
