RT Effects for PhotoJPEG
I figured out a VERY simple tweak to give you RT effects for the Blackmagic – JPEG Easy Setups.
Without giving away too many details, there’s an RT Enabler txt file somewhere inside the Final Cut application file. Back it up to another folder so you can always restore it later if need be. Now open it up (the real one, not the backup) in TextEdit. Inside there’s a section for OfflineRT (PhotoJPEG) surrounded in astericks. Below this are several self-explainatory lines for max width and max height allowed, which are currently set to 320×240 and such. Change these to 1920 and 1080 (or 720 and 486 – whatever). Change the max spatial quality to 800 or so.
That’s it. It just works. The only prob is that FCP gives you a warning whenever you start up. Just make sure you have “Report Dropped Frames on ETT/PTV” checked.
I can’t stress how great this is. I have a regular gig that requires only simple dissolves. I had been capturing everything at DV and later re-capturing at Uncompressed. Now I can skip the re-capture process and just take the footage in at PhotoJPEG for offline and online.
And if the info I just provided is somehow considered “shady” or inappropriate, I really fear we are becoming more faccist by the minute.

Hi Sean,
It is possible that this works now. It always worked in OfflineRT resolutions but never in full resolution SD or HD. G5’s are so powerful now that they might have crossed the threshold where this does or doesn’t work. We’ll check it out soon but probably after IBC as we’re flat out now. Thanks for the post as it would be great if this worked 🙂

Hello Sean,
Would you mind sharing the config for your G5?
Thanks in advance,

A very detailed description of my config is actually in the thread about the bad 5.01 drivers.
It doesn’t matter what your config is when you do this – it will process it all as Full RT. What this “tweak” (or should I say hack) does is trick FCP into thinking that JPEG @ 75% quality at high resolutions falls within the OfflineRT category.
From what I’ve learned playing around with it, I pretty much get one basic effect at a time w/o dropping a frame. So I can do a dissolve, or I can do a Basic Motion resize. But I cannot dissolve between two clips that have been resized w/o getting dropped frames. Make sense?
If you use more effects, then the trick is to force render “Full” before mastering to tape.

Luke, like I just mentioned to Gary, Apple purposefully prevents any RT effects for the JPEG codec if it is larger than 320×240 and the spatial quality is higher than 36%. Every effect shows up as a red bar. It doesn’t matter if you have a quad processor 4ghz G6. The enabler script prevents JPEG from being RT at high quality no matter how fast the machine.
This tweak does away with that, so it can and does work.

Very ingenious Sean. Alot of us realized how good the jpeg codec was quite awhile ago but were frustrated by the abject lack of concern from apple heads. It is a great codec to store finished masters at. Thanks for your determination to move us forward on a codec that has great respect but unfortunately gets ignored by the code writers at apple.
On an unrelated topic did you perhaps notice that the link function in fcp 5.02 doesn’t seem to work
It did in 4.5. Any work arounds for that Sean?best

What is the link function?

The link function enables you to link together a number of clips together as one clip
Say you want another piece of sound with a different piece of video. Link them together and away you go. Also you can link say dat audio syncing it with the video.
It used to work but I can’t seem to get it to work nowMike b

You mean just Command-L? That’s strange. I’m sure I’ve done that since upgrading to version 5, and I never noticed that not working.
Anyway, I’m not some programmer or hacker or anything like that. I wouldn’t have a clue how to solve that. I just figured out the P-JPEG thing by dumb luck.

[Sean ONeil] “Anyway, I’m not some programmer or hacker or anything like that. I wouldn’t have a clue how to solve that. I just figured out the P-JPEG thing by dumb luck”
You’re still a rock star. I often do animated or MG offlines at JPEG 75%, and this just makes my life so much easier (I REALLY could have used this info last month).
Thanks from everyone who likes the PJPEG codec

hello, i cannot find this file anywhere at all — i have fcp 5.0 — can you show us where this file is? thank.s.
