thanks a lot for this one, Ken, very useful info!


Mabe the following is of some interest for Mac users* in this context.

*This uses QuickTime player objects and one cannot say that
QuickTime is "optimized" for Windows or vice versa ;-)

I made some test about 2 years ago to see how fast one could resize
large images in Rev. I timed the same actions for referenced images
and for players.

The test were made with OSX on a G4 with 1 Ghz and 1 GB RAM!

1. I set the filename of a Rev image/player
2. computed the correct proporional thumbnail size from the "formatted  
dimensions"
3. locked the screen and
4. resized the image/player

Dimensions are in pixels, times in milliseconds.
Thumbnail sizes show the max height/width.

Image dimensions: 2560*1920
Thumbnailsize: 60*60
Rev img: 1786
Player: 78

Image dimensions: 2560*1920
Thumbnailsize: 100*100
Rev img: 1822
Player: 85

Image dimensions: 2560*1920
Thumbnailsize: 150*150
Rev img: 1896
Player: 75

Image dimensions: 2560*1920
Thumbnailsize: 200*200
Rev img: 1822
Player: 79

Image dimensions: 2560*1920
Thumbnailsize: 300*300
Rev img: 1924
Player: 76

!!!!!
Image dimensions: 3440*2580
Thumbnailsize: 150*150
Rev img: 2991
Player: 74

Very impressive I think, hope some find it useful.


Best
