Performance and image size

http://www.boinx.com/chronicles/2011/7/1/performance-and-image-size/

what do you mean by, “scale ‘down’ to 200% of target size”?

Also, often when I use other programs to convert still images to video the images become “soft” after they are rendered; are the images still sharp with FotoMagico after they are rendered?

I will be creating a slide show, and there is an 80" flat panel available to show it on via DVD…but I do not want the show/image to take up the entire screen…is there a way to size the final show to fit maybe just the center portion of that huge screen .?
thanks

How can I undo the scale funktion???

it would be more helpfull if you would write the actual size you would recommend to make a good quality slideshow

It would be helpful if you could clarify the last paragraph with specifics on how to resize in Lightroom for example. Does anyone moderate this? I’m a new user and trying to optimize my images. Scaling “down” to 200% of target size resolution? Accustomed to thinking in pixel dimensions and dpi so any additional detail would be helpful … Thanks.

@SBBMaine Thank you for using FotoMagico and taking the time to comment on this thread. Unfortunately, the minimum size for a slide is not easy to determine. It depends on the resolution of the device you want to show the slide show on. For example, if you want to use an HD projector, a full screen image would be 1920x1080. However, if you Zoom in by 200%, then your picture will need 3840x2160 pixels if you want every pixel of the screen be used. Once you’ve created your slide show, you can let FotoMagico optimize the pixel size for you.
