I have just purchased composite lab & tried my 1st green screen test.I used a static backgroung & 116 frames of green screen footage from youtub. I then rendered my project using various options, all of which took about 3 minutes to render 116 frames. Is this normal? seems slow!
I have a sony Vaio 1GB RAM 1.83ghz processor.
Can anyone tell me how to speed up the rendering process.
Many thanks

As far as I know, that is roughly how long it should take.

If you wanted to increase speed, you could get more RAM or a faster processor. Also, quitting any other applications could help to gain a little bit of speed.

Yeah that render time sounds just about right to me... you might also try getting a better video or graphics card for your computer.
It also depends on your video quality... standard definition will render faster than something shot in high definition so look into that as well.
But yeah... anything you can do to help the program run faster... shut off other programs/get more ram/video card... you should do that.

Render speed is an interesting topic, I have been thinking about this as well. I have been working with 3D applications for years now, so I'm quite used to waiting for the rendered image/video. As suggested before, you might want to think about updating your hardware (or leaving more resources to VisionLab Studio (=> e.g. not watching Videos at the same time)). That's basically all you can do. I don't know how much potential is left for tweaking the algorithms used, but as this is something only the programmers could do, this thought might not be that helpful wink

Regarding the: video or graphics card
Is VisionLab Studio really using the video or graphics card for rendering the effects/frames? This would be great news as my graphics card is near to retirement and I'd really like this 'cheap' way of boosting render power smile

I own composite lab as well and that's actually pretty reasonable rate. 100 frames usually take around 3 minutes for me too and I'm running scrap pile reject wink. So yea, don't worry about it.

Afraid not, VisionLab doesn't use the GPU at all. The main bits of hardware that would help performance would be the CPU and memory.

As has been touched upon by others, there are several factors when it comes to rendering speed:

1. The processing power of your computer.
2. The resolution of your project (the higher the resolution, the longer it'll take).
3. The number of layers on any given frame. More layers means longer rendering.
4. The content of those layers is also important - 10 layers of low res still images could render faster than a single layer of intense particle engine effects.
