Hi
Now that’s a good question.

Are you following the recommended procedure at the top of this forum?

Render / convert times depends on loads of factors.

How efficient is your pc, the cpu, the ram.
Have you applied the recommended system tweaks.
Do you defrag your drives.
Do you turn off all background processes, anti virus etc.

Converting what to what?

If you are rendering a mpeg to mpeg with the same settings, then it should be quick.
If you are rendering Mpeg to Mpeg with different settings, it will take longer.
If you are going from Avi to Mpeg then it will take time.

If you are capturing and working in Mpeg use the same settings throughout.

With what content.?

If your project contains loads of filters, transitions, titles, audio etc
Then it will take longer than a simple project.

As to your original question, yes 5 hrs does seem a little excessive.

So what was the original properties of the video.?
What is the properties of the rendered video?

As a comparison.
I have an AMD Athlon XP 2500 cpu, and 1024 ram.
Rendering Dv-Avi to Mpeg2 (dvd) takes about 2.25 times the run time.
Faster and more efficient pc’s will probably do in real time.

HD times are even worse

I just transcoded MpegHD to WMVHD and the results were pretty slow too. It took seven times real time for VS9 to complete the job and MS7 takes the same amount of time.

And the machine it was running on was short of a dedicated AV workstation but still pretty good: AMD X2 4800 (95+% utilization of both cores during encoding), 2GB RAM , RAID etc.

Microsoft's WMV encoder is notorious for being extremely slow. Videostudio doesn't do the encoding itself, it relies on Microsoft code to do the work, so I'm not surprised that other applications like Media Studio or Windows Movie Maker experience similar conversion times.

Dual Dual Cores

Post by bablukas »

On that note, does anyone know whether the Ulead software can utilize more than one dual core CPU?

opened a can of worms!! just followed the tutorial which said set avi in, dvd out, have played around with other settings and get much the same. the hard drive is 200gb slave dedicated to handling video but the program is on master drive though I cant see that being a problem. the camcorder is Samsung vp-d453 digital. Am I to assume that the best rendering time I will get will be about two to three times the video length?

I have a P4D 840EE, which appears as four processors (two physical, two logical) in Task Manager, and during MPEG encoding, I achieve about 60 to 70% utilization. I figure two physical processors are doing encoding work (accounting for 50%), and the rest are from I/O, the Preview window, as well as other processes I'm running.

I think what I'll do sometime tonight is transcode an identical AVI file using a single processor (by switching HALs, not by changing the processor affinity mask), and report back with the results.

Hi daddygez

With the pc you are using I would say yes when converting DV-Avi to Mpeg2.
If you capture Dvd (mpeg 2) edit, then render to Dvd (mpeg 2) using same as project settings ( which should match your capture settings) then I would expect less than real time.

So what are your capture properties.?
What are your ‘Create Video File’ Properties?


I earlier mentioned project content, when I use the ‘Album’ transitions I find rendering very,very slow, to the point that I try to avoid using them. Which is a shame.
