(I’ve attempted twice to render a 90 minute clip of footage shot in 4:3 at 60i, 720×480 resolution on Vegas 8. I rendered the footage in mp4, 720×480 resolution, progressive scan, .9091 pixel aspect ratio, a constant bit rate of 4,000,000, and at 29.97 frames per second)
Is the original footage DV? Why don’t you render as DV? MP4 is way harder for a CPU to edit than DV. I gather the other person isn’t using Vegas to edit with. If he is, you can sync each track very easy using the audio waveform, save the .VEG file, give him the files and the .VEG file and he can open it in Vegas in sync like you made it.
It’s always a good idea to render to the same format as the source files if it’s going to be edited again. If there are no effects added or fades, vegas won’t recompress the video. The quality takes a hit everytime it gets recompressed. -
That does seem rediculously high for a machine like that. I’ve never ran windows on a Mac before though. Are you adding alot of effects?
Some effects add tons of time to a render. I tried Boris Continuum noise reduction on a 12 minute SD video last night with a 3.4 dual core laptop, Windows 7 64 bit, and it took several hours. -
My old Canon GL1’s manual said it had to be recorded all the way through in one take in order to get timecode correctly on all the way through the tape. I guess Sony cameras don’t have to.

I always have to record all the way through new tapes to put timecode on them before using them in a project. If I didn’t, it would start the timecode over with each new event. Can you try this with a new tape and see if it helps?

Your camera captures AVC/H264 files which are very compressed and you need an i7 to get a fast preview refresh rate. For this project, if your only going to make a standard def DVD with the files, you can convert them to DV by rendering them to DV widescreen. Then you should be able to edit them the same as you have before. To edit AVCHD with a not so super fast computer, alot of people are using Neo Scene by Cineform and converting then to a Cineform AVI. Vegas had this codec free but stopped when Vegas Pro 8 came out. It’s an intermediate lossless format that is alot easier on the CPU and can be edited on slower machines with a much better preview rate. There’s a free demo you can try here.

Hope this helps, Danny Hays -
If your using Vegas Pro 10b or c, there’s a bug causing timecode to start over with each new event. This bug was brought to our attention by Mike K. and sony is aware of it. If you have 10a, that should work.

I can use the Intensity Shuttle with vegas but it doesn’t see the BM MJPEG format in the capture formats, only MXF which looks great, and the uncompressed 8 and 10 bit avi formats, whis as said needs a raid array. I gather your going to capture straight from a cameras imager via component or HDMI with the BM device right. The SDI capture needs the full bandwidth of uncompressed in order to work. “From the BM site”
(Uncompressed Video Quality
SDI uses a higher data rate than DV, so it’s got the speed to handle full resolution video in standard definition or high definition, completely uncompressed. That means you can preserve video quality until you need to compress the video, such as the final compression pass for streaming or broadcast.)
I’ve been looking at the LaCie ToBig USB 3 raid 0 drive, specs showed it’s read/write speeds to be high enough to handle the uncompressed formats, Haven’t tried it yet though.
The Asus MB P6X58D-premium and -E work great with the BM usb 3 devices by the way. Danny Hays, Universal Studios FL. -
On the render as window, drop down the frames pre sec and choose 29.97
-
Are you rendering to the same framerate as your Vegas project settings, like 29.97 or 30 fps?
-
Is your camera, video files Sd or HD (HDV)?
