Widetrack,

It sounds like you're capturing to a P4 CPU or one of equivalent performance.If so, I'm not surprised you saw capture soak up the CPU to the point of nearly locking up your machine.

That is not a fault of the product, just that capturing lots of pixels takes a lot of CPU (and disk).

Tried BMD Drivers with Vegas7 and it didn't work.

We are having some problems getting it to work on XP with Vegas8. What version of Quicktime are people using??

I was toying with the idea of picking up intensity seeing as there are new drivers available. Does anybody know if it works with Vista64?

Yes, the latest v1.8.8 Intensity drivers work quite nicely with Vegas in Vista64.

HANDSTANDS-DOUBLE BACKFLIPS-YEEHAA!!
its been 5 or so years we've been waiting for this to work accurately - and it now does. Vegas now deservedly qualifies for the new "Pro" in its name.
It works on Xp & Xp_x64 consistently & accurately.

It appears to be capable of full10bit output -
A clip captured via the capture utility at 10bit is definitely 10bit.(checked it in Quicktime plus file size indicates its 10bit))
When this clip is re-output using the following settings it passes straight back out to the Digibeta (at 10bit) without doing a prerender -
Project Settings : 32bit
Preview Device: Encode at 10bit
Output template(in Print-to-tape): 10bitYUV SD

Thank you a thousand times BMD & SCS.

Thanks guys,
I think I'll pick one of these up. It sounds like it's worth it just for the video output.

As of May 22, 2008, Blackmagic has released v2.0 XP drivers for the Intensity and Intensity Pro. The 64bit v2.0 drivers were released as of today, May 29.

Has anyone tried the latest Drivers - "6.7" ??
Just wary of upsetting what is already working.

OK, I am assuming many here have been getting systems working with these new drivers. I am getting ready to build my new computer to host VV and BMD, Deck link Extreme. So the question is do you capture with their software or can you do it within Vegas? Also, what codecs does it all support? Can you capture say as standard DV or do you only get to do full uncompressed huge files? I want to both but to be able to select. Obviously drive space and speed is one thing I am considering. Thanks

Hi Gary

I currently capture with either Vegas or Premiere (which is on the same system). Basically in Vegas you can only capture SD YUV Uncompressed files with the BM Cards, in Prem Pro you can capture to uncompressed or the BM Mjpeg Codec (this is about 10 times smaller, and I can't see a visability quality difference), although the files take more processing power to decode than the Uncompressed codec. To be honest I haven't used the BlackMagic Software for capturing, as I was under the impression that it only captured to mov files (although I haven't looked recently). I was also under the impression that the BM Cards could not capture standard DV in fact I am 99% sure that they can only capture into their own formats, well I certainly haven't come across any where I can specifiy other than this.

But to be honest if you have DV stuff to capture just capture with your standard Firewire port in Vegas.

Matt,

thanks and yes for those items that are standard DV I would use firewire. However, I also feed in Betacam SP and other sources that are available best at component levels. I was not sure if BM would let me choose a compressed codec directly in Vegas capture or if I could use their capture software and standard codecs and then drop it on the Vegas timeline. On the BMD website the Decklink HD Extreme card promo video suggests that Vegas like other software offers a drop down selection list, but I can't confirm it. I am building a new computer for Vegas and wanted to use the card for the capturing card to Vegas for the analog items I have in the studio plus use the HDMI or SDI input for other decks and cameras. Plus use it for monitoring.

Uncompressed is good but need fastest drives and lots of it to do that and really as you pointed out not needed. I was used to my old VM/plus with scaleable MJPEG on component and regularly used a 3:1 compression ratio and worked great. Todays world is a bit different.

So this is what I was asking, how does BM now interface or not with Vegas for capturing, embedding their codecs in Vegas and offering others that Vegas can use. Thanks

Biggest problem I can see is Vegas cannot handle 10bit YUV without truncating it. Probably not a big issue with master tapes that are already graded but could bite you with camera tapes. Some time back someone here tried their hardest to edit SP with Vegas and the results were pretty ugly.
If Vegas could read 10bit YUV into it's 32bit pipeline that should change but as far as I can tell it doesn't do that as yet.

As far as I can tell it does use 10bit YUV through its pipeline when in 32bit mode. Farss , why do think it is being truncated?
I could be wrong though - would be great if someone from Blackmagic or SCS (or even someone that has even more knowledge than both of them - hint - Glennchan) could wisen us up on this.

We are successfully using Vegas's Capture and Print To Tape all the time, don't know why you would want to use the BMD standalone utility(media express). For capturing lots of clips we mark, save and use EDL's - saves lots of time and is repeatable.

I have no easy way of actually testing this however:

a) In Ppro I get a choice of capturing 8 bit or 10 bit. In 10 bit the file is larger naturally and larger than the one Vegas captures.

b) In the Vegas FAQ it's stated that Vegas does not support 10bit YUV. It even goes on to say why 10bit could be a good idea.

c) The last word I recall from the good SCS folks on capturing component through BMD cards was it's not supported. Damned if I can work out how it could not be supported as with the right card the capture processes is blind to what the source is largely.

I'd really love to be wrong on this and yes it'd be nice to get some facts from SCS once in a while.
