Hello. Does anyone know if film speed can be slowed down to "slow mo", or sped up for "fast forward" type effects with VisionLab..? I see the "SPEED" variable listed, but not sure if that is just for the different overlay effects, or if it references the actual speed that the source movie file plays at.. If anyone can advise, that would be appreciated.. thank you much!

Right-clicking a clip on the timeline and changing the Speed will change its playback speed. Numbers under 100% will slow it down, and numbers above 100% will speed it up.
If you run into a command that you aren't sure what exactly it does, feel free to try it, and see what happens. You could always look it up in the manual, too, but experience is a great teacher, and using the tools is often the most effective way to get familiar with them and remember what they do, and where they are located.

I've been using After Effects more lately so I'm not as familiar with Vision Lab as I should be to answer this post. I can, however, say the pros do it with the frame rate during the recording phase. The standard rate NTSC is 29.97 fps. A higher fps will produce the slow motion effect you want and do so with way more clarity than just playing it back at a lower rate since merely slowing down the frame rate simply shows the frames at a slower rate severly affecting the picture quality, whereas recording at a faster rate, produces more frames resulting in much better picture quality at the slower play rate. So, I suggest using a camera that allows you to adjust the frame rate during recording. Otherwise, you're pretty much stuck with the lower picture quality playing back at a lower fps. Many software packages use keyframes and digitally fill in the "missing" frames, but it's obvious to the trained eye. However, if you're not looking to release anything for commercial use, you should be fine with the slower playback method.

Ah, good point FXhomer32915.. my JVC camcorder can only shoot at one speed.. but on my next camera purchase i'll definitely be looking for something that can vary it's shooting speed..
i guess that's one of the downsides or making purchases before one knows exactly what features they should be looking for.
