New Aggressive Cache in recent AJA Kona drivers enhances playback performance
on Nov 12, 2011 at 3:13:43 pm

I got the green light from the nice AJA folks to share some information that could be helpful to Mac users of Adobe CS5.5 Premiere Pro.. For anyone who has updated AJA drivers that might still be having some playback issues with their Kona output with certain formats, try this.... Right click on your sequence to open up the Sequence Settings window. Then click on Playback Setting to open that window. At the bottom right check Aggressive Cache. Then playback your sequence while watching the external monitor fed by the Kona.I found that it can really help things out. It is documented in the new release notes and manual.

I was going for the double entendre sense of the word.

You had to be there, I guess.

I don't get it either...sorry.

BUT, I did get this to work. Smooth playback on Canvas, and Viewer export to external monitor too. Leave it up to AJA to be the first to solve this.

The latest drivers and this tip are very helpful. If only AJA didn't hate me for trying to go cross-platform with DNxHD.... Playback for that still seems pretty awful.

Thanks for the heads up about DNX. I havent tried decoding or encoding yet, but I will this afternoon. It really seems next in line to replace Prores since Apple dropped the ball on the professional video community. Wish me luck!

UPDATE

Josh, you are correct. I converting a 30 sec Prores master in AME to DNX. Then I made a sequence from that clip. I set the Kona 3 to Aggressive Cace and tried both HIGH quality and MEDIUM quality. I played it on the timeline and PrP struggled with both settings, dropping frames left and right. Its time to communicate this to AJA since DNX is a real up and comer. Thanks for the info!

On the bright side, AJA is showing support for DNxHD in their Ki Pro products, which makes me think they're willing to support it fully in their I/O devices. One doesn't make much sense without the other.

Thanks for confirming the issue and helping get the word out!

Really? Is the Ki Pro Mini also supporting it? I think that device could be a great way to do a real time dump from the PrP time line thru the Kona's SDI output into the Ki Pro Mini SDI. This could avoid some of the long render times folks deal with for long form or graphic intensive projects. Kind of like the old dump to tape we all used to do .

Actually, I think the Ki Pro Mini is specifically what's getting it, although the press release does mention user requests to add it to the "Ki Pro line of products." They announced a Q4 2011 release, so it should be soon.

Thanks Josh. BTW I sent AJA our experience with the DNX files this afternoon. I think them and Adobe are a great match. They both are good listeners and they make great stuff :D
