7 layers 24pN in real time w/AxioHD

Didn't know how to better get your attention :)

With permission from the Axio product manager at Matrox, I would like to say a few things about P2 MXF support that was demoed at NAB2006. As the beta version of AxioUtils 2.5 has evolved since NAB (can't mention release date, but it's very soon), a number of refinements now exist and are working perfectly with P2 MXF. Suport for Sony XDCAM MXF also exists, but I have only tested with the AG-HVX200.

At present, Axio (with beta AxioUtils 2.5) has native support (direct import of MXF files to the Premiere Pro 2.0 timeline) for EVERYTHING* the HVX can throw at it, including Native modes, variable frame rates, DVCProHD of any size, i or p or pN, DVCPro50, and of course DV25/DV. *Please give me till Monday to fully test 1080/24p...but I have tested everything else.

The P2 workflow with Axio works exactly like it was meant to be: offload mxf files direct from P2 cards via camera or other USB2.0 device such as P2 Store (mine's on order), import to PPro2.0 for instant placement on the timeline.

OK, here's the really exciting part. Due to the lower overhead of 24pN frames (no pulldown needed), Axio's performance increases 75%!

For this test I used 24pN (1280x720) footage shot at 60fps.
My system is an HPxw9300 with dual Opteron 280 dual-core processors; 4GB RAM, 4Gb dual-channel fiber Rorke Galaxy HDX running WinXP Pro.

V1 = 24pN/60f footage, 100% opacity, scaling 100% (motion, scale and opacity are Adobe effects)
V2 = 24pN/60f footage, 100% opacity, scaling 30%
V3 = same as V2, placed in a visible spot
V4 = same as V3
V5 = same as V3
V6 = 24pN footage, 40% opacity, scaling 100%
V7 = same as V6

These 7 visible layers will all play in realtime without a render warning (red bar in PPro2.0). Substitue photo stills @ 1280x720@72ppi for video layers above V1, and the layer count increases to 13 layers RT (on my system).

Yes, this is only one specific type of test, but it is the same test I've been using to determine real-time layer capability. Axio has a particular workflow that requires the use of Matrox effects (and/or Adobe motion effects). Adding effects decreases the amount of realtime capability as one would expect.

With 720p/60 footage, I can get 4 layers realtime. This was my former benchmark, so by working in 24pN, I get 3 more layers, or 75% increase.

Please pardon my excitement about Axio, but this is HUGE news about an editing system and workflow that supports you and P2 MXF (including native shooting modes) with native DVCProHD codecs (and others).

I'm in Utah at Salt Lake Community College. Anyone in the vicinity who would like to see Axio at work, contact me privately. As a favor to a superb product and programming team, any of you on the East coast who would like to see Axio, go to:

Stilll scraping my head together after seeing 7 layers RT!:love4:

Just did this in FCP 5.0.4 on a DP 2.5 running off a single SATA drive.

Played back in realtime with a green line.
 
Excellent! I'm not familiar with FCP. Does it put up a green line everywhere, all the time, for any part of the timeline that plays real-time? To the extent that FCP is similar to PPro2.0.....a green line in PPro2.0 would indicate an area of the timeline that has already been rendered.

Not saying you're wrong, just puzzled by the green line.

In my 7-layer example in PPro2.0, I got neither red or green lines...it just played as if it was a single layer with no render. Was this your experience too?

Another question about your experience with FCP in this 7-layer test....
just to make sure you're not comparing proxy or offline-res footage to how Axio handles things ;)

Would your system export this same timeline region to tape in real time? Or export to DVD/MPEG2, Flash .flv, Windows Media .wmv or Real at twice real time?

Yes, in PPro, QT export is a little behind the 8-ball at the moment, but in the Windows world, QT is not so popular....but I do believe it's coming :)

Have to admit, with the Rorke Galaxy HDX and its sustained read speeds of 411MB/s at RAID 5, it's a little hard to believe a single SATA drive could sustain 7 layers of 100Mb DVCProHD on its own without being striped!

But I'll take your word for it.

John, small correction, you only doing 7 layers of 40Mb/s (720pn24 is not 100Mb/s) DVCPRO-HD most dual proc systems can do that off a modern SATA drive. However, 7 levels of 720p60 would be impressive, it make sense that you can only do four.
 
Yes, good to know. Better to be exact when discussing hardware and capabilities. Certainly makes 720/24pN a desireable workflow.

Main purpose of my original post was to announce that AxioLE/HD with Premiere Pro 2.0 has got the P2 and XDCAM MXF workflow happening with support for all the HVX's shooting modes. That's big news in itself!

With the HVX200 at the center of the under $10k universe, it's nice to know that universe just got a whole lot bigger :)
