Screen Scraping vs Transcoding ?

All I want in most cases is a .mpg version of a given video.

Have been getting pretty good results lately with screen scraping as opposed to transcoding.

It is faster and works with any format/CODEC that VLC will play (which seems tb most) .

The only Gotchas I have found so far:

- Inadvertant playing of some other audio during capture
- System sounds/alerts

Specifically ReplayVideoCapture vs Super.

Am I missing anything?

What do you mean by "screen scraping"? If you record what's on your screen, you're still going to be transcoding, as you must compress the video to keep it at a decent size. If you stored the raw images from your display, the video would be huge.

Thus confirming that all this is way, waaaay beyond my pay grade... -)

Screen Scraping as in using a utility (ReplayVideoCapture) to record what is in a predefined area on the screen.

With RVC, it seems like I control the size (i.e. resolution) of the recording by sizing the window that defined where on the screen gets recorded.

What exactely are you trying to accomplish? Record gameplay of your PC's screen or recording of content played through TV tuners through Windows Media Center????
Capturing your screen requires a capture utility or hardware to capture the monitors signal as well as codecs for both ideo and audio and both require going from uncompresed video to some form of compressed video-depending on your choice of codec. You state you want a mpeg-which means most likely you will end up with h.264 video.

Yeah, what's the source? If it's a video file you have that you want to convert to MPEG2, then you just need the right software to do the conversion. Doing the re-encode via playback/capture would work also but seems more difficult than necessary.
