I’ve got a dual xeon system with a 133mhz bus for the decklink hd pro card, and i’ve got the same issue. I guess it isn’t the sustained read that’s not fast enough, but the seek time of the hard drives to “jump around” to read both shots at the same time. I wish there was an easy way just to disable realtime disolves so it renders instead.

I’m currently using Premiere Pro, but am interested in switching to Vegas. Too bad it won’t be supporting HDV and Uncompressed HD on the same timeline, that is what I really need for my documentary work. Actually, the trial of vegas 6 freezes up on startup so I havn’t been able to use it yet.

Here is the “hd” system I want to run Vegas on:

Dual p4 xeon nocona processors on a supermicro X6DAE-G2 mobo.
Decklink HD Pro (single link)card
M-audio Delta 1010lt sound card.
Nvidia 6800gt pci-express display card.
8 drive sata raid-5 on a Highpoint 1820a.

Currently I input HD SDI with panasonic 1200a deck and/or any HDcam deck I can get (if that is the format) and I’m monitoring HD via Decklink pro’s analog hd component out. I’ve been told by BlackMagic that they can only assure sound sync with their audio out SPDIF driver, but I havn’t found any difference with using the m-audio card. With 10 channels out you can do surround quite effectively.

For output I’ve mostly been making uncompressed quicktime files as masters and shipping them on a firewire hard drive to another company where the spots and other material are put onto a master tape. No HD tape output as of yet, but if I do I’d prefer 1080i output to HDcam via sdi, HD-D5 would be better but is too costly. Everything I shoot or create I do at 30p so that interlacing issues among different formats doesn’t become a problem. For NTSC tape output, i’m using a JVC Digital-S tape deck (digibeta or DVCpro-50 comparable sdi 4:2:2 format), and old fashioned Beta SP (uvw-1800) for those who want it.

hope this helps.

I second that. Some sort of compressed solution that can “take in anything” sdi, HDV, Panasonic varricam over firewire…..

I saw on the cineform website that Decklink HD card support was one of their NAB topics. Can anyone elaborate on this???

I’m a little confused. So most edit systems process in 8bit, but is that full 8bit 4:4:4 processing or the lesser 8bit 4:2:2 (YUV)?

It makes sense that a frame rendered in 8bit 4:4:4 RGB would loose information if saved in a 4:2:2 YUV, so I’d think 10bit 4:2:2 would be needed to compensate for the lower “U” and “V” resolution in the codec.

I’m not a video expert, perhaps someone who understands the 4:2:2 codec better could elaborate or correct me.

Thanks,

Well, I had tried that last week with the new 4.8 drivers, and i’m using the windows platform so that duplicate frame remover software won’t work for me. But i’m currious, does the plugin keep the timecode of the original clips?

I can set deck to upconvert to 1080i at 30fps, maybe i’ll have to do that to get true 30fps footage.
