Realtime Timeline Export

[Gary Kleiner]

[marmels] “is there anything that can avoid the rendering process and export in REAL TIME from Timeline???????”

No, Vegas is not a real-time system.

so you are saying its normall to wait for the computer to render and then it exports to VTR?

on average how long does it take to render 1 hour of dv footage with some disolve on your system ?? roughly how long?

does an expensive graphic card help rendering process in any way?

thanks

[Gary Kleiner]

Yes, you must always render. A one-hour DV project with no changes to the footage except a few dissolves should only take a few minutes.
A different video card won’t help.

to give you some idea, with an E6600, 2GB and arbitrary vid card, takes me approx 1/2 to 2/3 real time to render to AVI

print to tape then happens in realtime.

thanks guys

Gary Kleiner what processor and graphic card you use?

if i was to put 2 dual core xeon processors inside the pc
do you guys think that it will reduce the render time?

what is better for rendering CORE 2 DUO OR INTEL XEON?

iv heard that intel xeon are much faster and are usally used
for networking beacuse of the power the preduce. is this true?

thanks guys

You can do this successfully, as long as your transitions are not complex. Pretty much fades and cuts.

I use my export preview to DV cam via firewire, then i hook up a separate audio from my headphones out. I then take the RCA out from my camcorder along with the audio out from my computer and go in to either another camcorder, my standalone DVD burner, or a VHS recorder.
click play on the timeline

I have used this successfully a couple of times, only when i was in a time crunch. And there was nothing complex in the timeline, just a few titles and crossfades. It worked out ok for a preview copy for my customer, but i would never use this as a final.

I prefer to go ahead and render the final project export to miniDV so i will always have the footage for future use.

how long does it take you to export a 1 hour of footage to minDV?
what is your graphic card?
what is the CPU and ram on your computer?

thank you for your help

[Terje A. bergesen]

Exporting 1 hour of footage to Mini-DV takes one hour no matter what CPU, Graphics card, RAM, car or house he has. DV export is in real time. If his CPU is reasonable, he will probably be able to render real time for uncomplicated projects as well, any CPU not marked Centrino bought in the last two years should be able to do this.

thanks for your reply Terje A. Bergesen

what i ment by my message was how long does it take to export 1 hour of video to minDV INCLUDING RENDER TIME.

rendering does have to do alot with the CPU and RAM.

[Terje A. bergesen]

I am aware that rendering is CPU bound, it is less RAM intensive than most people think. In fact, for a video editing system the top four things that matter is CPU1, CPU2, CPU3 and CPU4. Next there is RAM. Video cards have no impact on rendering at all.

This means that exporting from time line to tap is not a real good measure of how good a system is since it will always take 1 hour to put 1 hour of video onto tape. This means that the fastest ANY computer can be is 1 hour. Some computers will not be fast enough to be able to do it, and therefore they won’t compete at all.

An imaginary list of computers and their rendering times would look like the table below, which isn’t all that meaningful. Either the computer takes 1 hour or it can’t complete the test.

Rendering to hard disk is a more relevant test since you don’t have the Mini-DV recorder slowing the thing down. Most modern PCs can render to DV-AVI a lot faster than real time. My PC, for example, takes around 5 seconds to “render” a 1 minute DV-AVI file consisting of two pieces with a straight cut. It would therefore take about 5 minutes to render an equivalent 1 hour movie. Rendering to MPEG-2 or H.264 would be another, and far more interesting test.

Computer name		Time to render
Super Duper Fast 8 CPU computer		1 hour
Super Fast 4 CPU computer		1 hour
Fast 2 CPU computer		1 hour
Slow computer		N/A
Slower computer		N/A
