Video capture - quick start/stop?

Hi, I am currently evaluating the VisioForge VideoCapture .NET package.
I need to be able to preview the live video, then start/stop recording to an AVI file upon user request.
I currently set the video mode to VFVideoCaptureMode.VideoPreview, call Start() to start the video preview, then either switch to VFVideoCaptureMode.VideoCapture without stopping, or instead call Stop() --> change the mode --> call Start() again.
Both methods do result in video capture, but this capture doesnt start immediately. Instead I see a video display re-initializing for a few seconds on every start/stop.
So my question is: Can the ViseoForge VideoCapture .NET package quickly start/stop a video capture in the middle of preview?
And if so, how can that be done?
Thanks,
Tal Davidson

Yes, it's possible.
Please check Main demo, Separate capture tab.

Roman thanks.
The use-case I am trying to develop is this: While the user previews a video on screen, he presses a 'start record' button, and the system immediately starts capturing the video to AVI till the user presses a 'stop recording' button.
Following your suggestion I looked a the 'Main demo', but there too (to-my-best-understanding) you can either run the grabbing in preview mode OR video capture mode, and need to stop/start when moving from one to the other.
Doing this, even programatically results in a long multi-second period till video capture beings after the user requests it to begin. So it doesn't achieve my intent of an immediate start/stop of recording.
Does the VideoCapture .NET API enable you to just preview a video, then upon a programatic request immediately start capturing the video (say to ASVI) without having to stop/change mode/start or anything else that results in a long multi-second wait for the the video capture to start?
Thanks
