[Emery] “So how does the Kona 2 handle this. Does it just add the pulldown before sending out the stream?”
I’m sure it handles it exactly how the Blackmagic does. It converts it to 59.94p upon playback. SDI doesn’t support 720p@23.98. It’s not an offical HD standard. Even if the Kona somehow did support it, you wouldn’t find any decks that would understand it.

You are viewing this on an NTSC or PAL video monitor, correct? The Canvas will display text at half-res because on an interlaced monitor it looks fine.

DVI is a digital connection, so that kind of thing couldn’t happen on a Cinema Display.

I tried two DV video layers on a 10-bit sequence. It stuttered and choked (didn’t crash or anything). So while it’s perfect for one stream, that appears to be it. I only have 2 gigs of RAM and an ATI 9600. Maybe someone with a tricked out system with 4 gigs of RAM and an X800 can try it out.

Their brain was on the iPod and the iTunes Music Store. MP3’s are specifically made not to work by dissallowing them to use RT-Extreme. It’s 100% political. MPEG2 video now works with RT-Extreme, but no MPEG audio.

I didn’t have time to do more tests. I tried 10-bit uncompressed SD on an 8-bit uncompressed sequence. It was RT.
The only pattern I can find is this. If it’s standard def, and FCP5 natively supports the format (Uncompressed/DV/DV50/IMX/PJPEG) then you get smooth RT playback in any SD sequence no matter what. And if it’s unsupported SD Quicktime format, it at least tries to play it back in RT. You get the full frame rate although it’s not so smooth.
This could be a FCP5 Dynamic RT thing and have nothing to do with the Decklink. I have no way of knowing that. AJA owners should try it out. All I know is that Apple never mentioned this capability, and in a Q&A session I read yesterday about FCP5, they specifically say you can’t do it without extra hardware (I assumed that meant without a Cinewave).
I’ve always know that RT playback for multiple codecs could be achieved if allowed. It’s a simple matter of telling it to fall under the RT-Extreme umbrella. My suspision is that Apple didn’t want to allow it for political reasons as well as giving false expectations to what should be RT. But now it works (for SD at least).
Yes, Blackmagic mentioned a very vague blurb of this capability. Then when asked to be more specific, Luke mentioned that he wasn’t sure 100% but that he thinks it means 8-bit and 10-bit on the same timeline. Nothing about DV, etc.
I didn’t try Animation with alpha. Will do when I get a chance. The Animation I did try (no alpha), like I said, had tearing and slight stuttering. If it helps, the Media 100 file did have an alpha and the results were similar. Even with the tearing, this is still a massive improvement. There are probably plenty of situations where a graphic artist gives you an anmiation video. You can now drop it in and get a very good idea of what playback looks like. No need to convert and no need to render until it’s time to master to tape.
On a side not, FCP5 with Tiger and the Decklink 5 drivers is so far VERY stable and solid. It’s hard to describe specifically, but the quirkiness I had with 10.3.9 and FCP 4.5 seems to be gone. Everything feels quicker and more responsive. I worked all day yesterday without a single hiccup. The only problem I had was no video output at all – but this was due to the Automatic Duck plugin. Removing that solved it. I’ll know for sure how solid it is when I export to tape next time. Before, I experienced black flashes whenever my reference cable was plugged in. I’m anxious to see if that problem has gone away.

Same here. I don’t see them. I did open up a Boris title from an old FCP4 project. It opened up fine.
I’ll try creating a new folder for the plugins.

Ok, the remaining tests didn’t turn out so great unfortunately. On an Uncompressed HD sequence, all SD codecs do show up with an orange RT-Extreme bar, but playback is very poor.
I tried a DVCPro HD 1080i clip on the uncompressed 1080i sequence. It wasn’t even RT-Extreme. I got a red bar. Same thing when trying 8-bit on a 10-bit timeline and vice-versa.
So with standard def everything is incredible but HD isn’t there yet.
-
Ok, I’m not halucinating. This is for real! Every single codec shows up as orange RT-Extreme. Every one! Unbelievable. Why wasn’t this touted? FYI, I have dynamic-RT on, so that might be important.
FCP5 with the new BMD drivers have turned our Decklinks into Cinawave cards with the RT option. I ran a several tests and I’ll get to that. Here are my results on my dual 2.5ghz, 2 gigs of RAM, and an ATI 9600. Results are one stream playback.
ALL ON THE SAME BLACKMAGIC 10-BIT NTSC SEQUENCE
8-bit NTSC – Real Time
DV25 – Real Time
DV50 – Real Time
P-JPEG – Real Time
IMX MPEG2 – Real Time
Animation – Full Speed PB but w/ occasional stutter and tearing
Media 100 Lossless – Full Speed PB but w/ slight tearingI’ll post more results in a little bit. I’ll try a DV timeline next. I’m also going to try HD footage on an SD timeline, as well as SD footage on an HD timeline.

I’m finding the capability to run multiple codecs in the same timeline. For months this was a rumor, then when FCP5 was announced it was dubbed untrue. But I have an orange RT-Extreme bar over a DV clip inside an Uncompressed timeline. It plays back fine with no rendering.
This could be a Blackmagic thing. Can anyone else confirm this?
I’m going to try more combinations. DV50, IMX, etc. Maybe even HD and SD can be mixed. I’ll post the results.
