Updated to 9, and now render times are off the chart.
Long story short... I've been tasked to splice together 3 clips. Open Title credits, 5 min film @ 720p, and closing credits. (total running time of 7min).
I crossed faded about 2-3 seconds of both the open title credits and closing credits with the main film.... no fx at all. My counter is STILL climbing at 36min for this. (EDIT it JUST finished) What could be wrong? I'm on a quad core box on Win7RC1, so my box isn't a slouch. I used to be able to splice clips together and it'd render in 30 seconds in Vegas 8 as long as I didn't have any FX on. Please help! |
What are your project settings?
What format are the credits in? |
Here's the info you asked for...
Project Settings Template: HDV 720-24P 1280x720 Frame Rate: 23.976 (IVTC Film) Full Resolution Rendering Quality - Good Adjust source media to better match. Checked Audio Sample Rate: 48k/24bit Main Video: Apple ProRes 1280x720x24 Frame Rate: 23.976 (IVTC Film) Credit Videos: H264 720x480x32 Frame Rate: 29.970 (NTSC) |
Well, you're transcoding a ProRes .mov file into HDV. You're transcoding a 29.97 file into 24p, and transcoding 720x480 into 1280x720.
Yea, that's gonna take a while in 9.0, 8.0 or any other editor. |
I was under the impression that ProRes was HDV

For the benefit of the newbies, care to elaborate?

ProRes is at the opposite end of the spectrum. It is a codec built primarily to edit high end HD material destined for film or television. Complete opposite ends of the HD quality spectrum. |
Further to Perrone's contribution:
HDV is MPEG-2 Long GOP ProRes is Intraframe compressed Which translates to : HDV uses a Group Of Pictures ranging from 6 to 15 frames and compresses video data based on changes in the image between "keyframes" or full frames. This requires significant computing horsepower as each frame needs to be "uncompressed" on the fly based on frames that have come before it AND after it. ProRes compression is done all within one frame, much as DV compression is, allowing for SIGNIFICANTLY better performance, albeit at much larger file sizes. |
And Shaun didn't even mention the issues of color space, or 1440x1080 pixels... etc.
|
And... ProRes decoding on the PC is done by Quicktime. While this does work, the implementation as Vegas sees it is rather slow.
ProRes is a great format - kudos to Apple for finally making it available on the PC via QT. Vegas, OTOH, has had lots of development attention in optimizing playback/rendering for DV; then, later, HDV; most recently AVCHD, because these are the acquisition formats of the masses. |
Understood. So for the future, if I'm working in Vegas, and I receive a ProRes video, should I convert it to a certain format before working in it?

Well, what would YOU do if you only had access to Vegas to splice clips?

2. Set project rendering to "Best" 3. Load main video(s) 4. Create titles at 720/24p and not upres 720x480 5. Export 720p finished master |
