Thank you for making SC. It's vast but the good UI and help make it easy to find your way around.

There are 2 feature enhancements I'm interested in:
1. The option of saving images in an uncompressed format, BMP and PPM.
2. Auto-capture faster than once per second. Though, I'm not sure how fast is feasible...  undecided

I could add #1 quite easily.. though keep in mind that PNG is lossless so gives you no degradation with small screenshot size.

For #2, i'll look into how fast i can make it, though if you really need to capture fast changing screen, you should probably use a screencast tool (see our review of such tools here: http://www.donationcoder..../ScreenCasting/index.html).

#1 doesn't make much sense until #2 is applied - but then it _does_ make sense, if you want to capture several shots per second, compression could end up taking too much CPU time... and yeah, a more specific tool might be better if you need to do this smiley

Hey mouser,

Screenshot captor can't capture the screen area defined by user when we are capturing from media players e.g.

media player classic
real one player
windows media player
winamp

but if u powerdvd it has the capture function by default then why screenshot captor use this.
 Sad
also the autoscrolling for image function is not quite good.it has few problems if you want i can show you the images that had problems.
I hope these limitations will vanish in next version.

Hi Mouser,

Thank you for considering adding these options.

A simple uncompressed format allows me access to the actual RGB screen data, for further processing.

Capturing at a fast rate is useful for screens with windows showing video or animation. I tried this option with hardware acceleration turned off (as you recommended), and it seems to be working fine.
I agree with f0dder that faster capture is best achieved with no compression at all.

Could anyone recommend a screencast software that stores the captured video as successive individual files instead of or in addition to AVI or flash?
