Kona 2 and Pro Res 422

[Gary Morris mcbeath]

Hi Glenn,

No on the acceleration; I think the only AJA product that offers ProRes accel or processing is the Io HD.

As far as capturing, I think your G5 dual 2.0 might be a little slow; I run a dual 2.7, and I cannot capture (over HD-SDI) straight to ProRes; somewhere (here in the pasture I think) I saw a workflow for capturing direct to ProRes via firewire, but I’ve not tried it.

I should add that I work exclusively in HD. I capture uncompressed (or sometimes HDV), then use Media Manager or Compressor to convert the files to PR for smaller working files and backup.

You don’t state what you are capturing, and whether via analog, firewire or SDI/HD SDI. That might give the info for others here to chip in.

Cheers,

Gary

ProRes capture requires a quad core G5 at the very least, if not an intel:

You will need to use your MacPro to capture ProRes.

Sorry to be the bearer of bad news.

I am currently working mostly with HDV from a Sony Z1 camera. I have been capturing to ProRes via firewire. This works great on the MacPro, (real time) and OK on the G5 (about 25% slower)

I want to start working with some better formates than HDV, considering the EX3. I am also getting more projects from other sources on DCVProHD and HDCam. So I would like to add the abaility to use SD/HD SDI.

The G5 is still a good machine, I just want to get the most out of it. I might just keep using the MacPro for capturing and finish, and the G5 for off line and basic cuts.

*Maybe its just the imac that does the prores at about 25% slower.

Thanks Jeremy, No worries on the bad news. I guess I will just use the G5 for editing and not capturing.

But the Kona 2 would work for capturing DVCProHD via SDI with a dual 2.0 G5? Some project I get are on DVCProHD and I will be outputting to this as well.

Without a doubt, it will work. Yes.

You will not likely be able to edit ProRes in HD either, with that machine. I have the same machine and it definitely cannot handle it…and I have a pretty fast RAID. It’s definitely the processors….in fact I can do Uncompressed HD but not ProRes.

You will definitely be able to work in DVCPRO-HD. It works just fine.
