This is what I usually do when I prepare pictures for IMCDB:

I have a movie saved on my computer and I open it in Quick Player. When I see a car I stop the picture and press "printscreen" key and copy the still image to empty word page. Then I copy the picture from Word to Paint so that I can save it in jpg format. This has worked so far. But today when I copied a picture to Paint I noticed the quality was not nearly as good as in the original still image. I tried every trick I know but nothing helped. There must be another way of doing this.

Is it possible to save pictures from Word-file (I mean not the whole file, just the picture) ?

What's the best way to convert mpg still images to jpg ?

Using Word is probably the most strange system Why not paste them directly in an image program ?

To do the captures I use Media Player Classic, I save to BMP.
Then with Paint Shop Pro I cut black borders and resize picture if needed, and then I convert to JPEG. There are also freeware programs that can do that.

Is Media Player Classic free ?

Can you recommend a good image program ?

I'm not especially talented at computer stuff

Can you do that also with the normal paint that comes with the win package? (haven't tried yet)

Yes Media Player Classic is free. And not hard to understand. I use it, it's a proof...

Yes, but I am not sure that it is easy to resize picture to the good aspect ratio if needed.
And as you can't select the compression ratio, it is a little annoying.

Few good free image programs :

Ok, thanks everyone. I try this weekend to get things work right. Have some interesting stuff waiting.

personally I use MPC for capturing and Corel Paint Shop Pro X for everything else reliable and good

Paint Shop Pro X has one thing missing compared to the 9 (that I use) : they removed the "automatic contrast enhancement", and aded a "clarify" feature that does not work as good as the old one for dark movie captures

you can´t stop the improvement...

I use Brightness/Contrast adjustment personally. Most of the time I'm not very satisfied with the automatic corrections.
