RENDER TIME (1 HOUR DV TO MPEG2) WITH XEON DP

coffeebean wrote on 3/2/2004, 4:52 PM

Hello,

I have scoured the net trying to find a simple answer to a simple question? I was wondering how long the render time in Vegas 4 of 1 x hour of footage with no effects at all would take using a Xeon dual 2.8ghz 533/400 with 2 gig of 2100 ddr ram. I know how long a P4 2,4 with 1 gig ram takes and I would imagine that the stated system would be far faster but there does not seem to be any real world times.

Thanks in advance
Patrick

Patrick,

I have a dual P4 3.06GHz Xeon (512KB L2-cache) system (1GB 2600 DDR, Win2K SP4) system and rendered a 1HR home video movie for you tonight. My source footage drive is a networked HDD (served from a Linux fileserver via Gig-E network) and the destination file is on a local 7200RPM disk. Here is what I saw:

-> Source footage: 1HR raw DV avi clip (13.7GB). Rendered to standard DV NTSC AVI file (720x480) --> 8min 03sec

-> Same source footage. Rendered to standard DV NTSC MP2 clip (using template: DVD NTSC video stream - 29.97fps, 720x480) --> 42min 36sec

-> Same source footage but using MainConcept 4.01 MPEG Encoder ( DVD NTSC LPCM audio) --> 23min 34sec

However, I think your render times will vary with the complexity of the raw footage. I noticed at times the rendering would speed up (not much happening on the screen) while other parts frames took considerably longer to render some (more movement in the video clip).

Thanks Ron,

For replying to my email and actuallt doing a trial for me. Impressive to say the least. I should have my
dual 2.8ghz Zeon 400gb striped raid drive and a 100 gb boot drive plus 2 gb DDR 2100 next week some time. I have been using a P4 2.4gb with a gig of ram and well it takes 4 and a half hours to render a 1 hour 50 minute AVI NO effects to DVD Architect compliant MPEG2. I am now confident that the unit I am getting will certainly do the job....cheers

hey, before you buy that new system, you do know that Vegas won't use both processors for rendering, right. Unless I am wrong about that, but I'm pretty sure I've read it a few times here. Makes me wonder what that box to check in properties is all about.

But the Mainconcept encoder can (their retail encoder). So, buy a copy of that too. :) As you say, it WILL help.

Vegas is multithreaded, but not very well. The second processor encodes DV (and I think decodes it too) and handles audio processing. On complicated renders the second processor won't do much. It's not worth buying Xeons for just Vegas... but it seems from the other posts here that the main concept encoder will definitely benefit.

it will use the second proccessor for rendering mpeg IF there are no effects or any changes to the file other than cuts ...
