PhotoJPEG vs Blackmagic 8-Bit Uncompressed
-
The Squared-5 DC30 Codec is MotionJPEG-A. The DC20 and DC30 cards used the old Zoran 36050 Motion-JPEG-A hardware compressor, and is almost identical to the 36060 chip on our IgniterX-family of cards.
The RT effects in FCP implemented by Squared-5 are just entries in the FCP enabler file. Graeme is right in that this stuff is almost completely undocumented, so the guy at squared 5 has spent a lot of time reverse engineering, or he has inside access to Apple.

Hey Matt – Do you have a DC30 Card installed? I have tried the DC30 PhotoJPEG codec out setting up a PhotoJPEG timeline and changing the effects handling to DC30 but when I throw DV files into the timeline they need to be rendered…
Is there any way to use this codec with a Kona card?
Cheers,

[Aurora Support] “The RT effects in FCP implemented by Squared-5 are just entries in the FCP enabler file”
“just”? if it works it works, right? 🙂 anyway, if you have a dc30 card they claim they use the hardware accelerations in that, and as a matter of fact they claim that they also use the graphics card accelerations as well, and also fix a number of bugs in apple’s rt extreme code. this is all from the squared 5 docs though, so don’t take my word for it…

i have a dc30 card, but not installed. it’s in a pc right now but i’ll try and put in a g4 i got access to and see how it works.
putting dv in a pjpg timeline might still need rendering, but what i did was capture at full res and 75% quality and putting that on a pjpg timeline with the same settings and it ran in realtime, which it didn’t before.

after testing it further it’s definitely not just an entry but actually their own rt extreme driver. telling differences include that the gamma is slightly different, the display flashes a bit when you start and stop, and it doesn’t deinterlace scaled down images. the latter is a major pain imho. if you set display quality to medium it does deinterlace the screen playback, but not the still image when playback stops. it can look really ugly. this is all without a dc30 installed btw.

dv out doesn’t work on my system with their rt enabler though. i get a small square in the corner of a green background and after a while fcp crashes. i guess i have to install that dc30 card to get monitor output if i choose to use their codec or just their enabler with the pjpeg codec then. or since i’m only using a single computer monitor i guess i can plug my second monitor output to the video monitor via s-video and using desktop preview or whatever it’s called?..

“DC30 Xact Driver includes RT support for Photo-JPEG; open Final Cut Pro 4 or
4.5 and select “Squared 5” for Photo-JPEG in the Effect Handling (System
Settings) of FCP and you’ll get RT support for Photo-JPEG at any frame size
(I call it “Online RT” because it is not limited to 320×240). If you have
Final Cut Pro 5, then you will have to wait for the next version of DC30
Xact Driver because the current version is not compatible with Final Cut Pro
5.Regards,
Squared 5″Is the reply I got! Sounds like we need to get the new driver.

perhaps we should let them know that their driver does not work with dv out. at least not on my system (4.5).
