Is it normal to take 11 hours to render an 80 min project in HD in Vegas Pro 10?
I am working on a series of video seminars. Just finish editing them, but now that I’m starting to render noticed that the longest video that is 80 minutes, it’s going to take about 11 hours to render.
My computer is fairly fast, these are the specs:Windows 7 Ultimate
Intel Core I7 CPU 860 @ 2.80 GHz 2.80 GHz
Ram 8 GB
64 bit operating system
Video card: GeForce GTX470, 1280MB GDDR5I’m using Vegas 10, the video is full HD 1920 X 1080. I’m using about 11 video channels and 2 of audio. The extra channels are mostly titles and photos. The channel with the video has no splits. Since I have to deliver it in DVD I’m rendering it as uncompressed Quicktime with MPEG4 encoding.
I have rendered commercials and songs no longer than 4 minutes before in HD, this is the first time I do something this long. My major concern is that I’m barely rendering the first one and I have 4 more to go (the other 4 are about 60 min each), and had promise the client to have them ready over the weekend.
Is this time of rendering normal even for a computer like mine?
Any comments and suggestions will be appreciated.
Thanks.

If you have to deliver a standard definition DVD, then you might as well render your project to DVD format (Mainconcept MPEG2, and use the DVD Architect Video Stream presets, then render audio separately as Dolby AC3 if you use DVD Architect). This should be substantially quicker to render than MPEG4. If you render to HD and then only use that to make a DVD, you’ll have another recoding step when you create the DVD anyway.
You can’t be rendering to uncompressed MPEG4 – it’s either uncompressed (you’ll get a massive multi-gigabyte file) or MPEG4. HD MPEG4 and AVC are fairly slow (very CPU intensive) to render – I don’t know what render times to expect on that spec of PC though.

As a matter of fact, I’ll be using DVD architect to make the final DVD. I’ll wait for the first one to be done (it’s at 89%) then I’ll do the other 4 the way you’re suggesting. I will just have to figure out how to set up the video and audio separate in DVD architect, never done this before.
Thanks a lot ☺

It’s actually quite easy. Just render your video to Mainconcept MPEG2 format using the appropriate DVD-Architect template (gives you a video-only MPG file), then render the project to Dolby AC3 format (gives you an audio-only AC3 file) using the same filename. Then drop the video file into your DVD Architect project and it will automatically pick up the AC3 file as well.

No way that should be taking so long. Until recently, I had the Q9550 CPU, which is a slightly slower version of your CPU (old Intel bus architecture, etc). Check out this one:
https://forums.creativecow.net/readpost/24/919135That same video, in Vegas 10, on the new machine, renders to DVD quality MPEG-2 in 11:32min.. slightly more than realtime. This includes the HD compositing… just rendering a finished video to MPEG-2/SD would be very fast.
I’m using Vegas 10, the video is full HD 1920 X 1080. I’m using about 11 video channels and 2 of audio.
It’s likely that your compositing, etc. is the bulk of your CPU time. I have a couple of 2 min videos that take 2-4 hours to fully render. But that’s with 40+ video layers, many of them greenscreen. In short, there’s no single right answer — it depends on what you’re doing.
The extra channels are mostly titles and photos. The channel with the video has no splits. Since I have to deliver it in DVD I’m rendering it as uncompressed Quicktime with MPEG4 encoding.
Why would you render to Quicktime or MPEG-4? You’re making a DVD. DVD is MPEG-2, there are basic templates in Vegas that allow you to tweak the settings. But rendering first to MPEG-4, you’re just lowering the quality of the final product, and spending more CPU cycles than you ought to (MPEG-4 is more compute intensive than MPEG-2).
I have rendered commercials and songs no longer than 4 minutes before in HD, this is the first time I do something this long. My major concern is that I’m barely rendering the first one and I have 4 more to go (the other 4 are about 60 min each), and had promise the client to have them ready over the weekend.
The first thing.. are you rendering multiple delivery formats? If so, you definitely want to pre-render your video. Once single video stream, whether MPEG-2 or AVC or Cineform, HD or SD, isn’t going to take a huge bit of CPU to process. Your project, however, very well might. So if you have more than one target, render the project first.When I make a Blu-Rayin a hurry, I render the final project to AVC, then from there to SD-MPEG-2 for DVD. Technically speaking, rendering first to AVC and then to MPEG-2 will lower quality. But in practice, HD to SD looks better than native SD, so chances are, it’ll be fine.
