Minimizing file size for Flash
i have made demo 10 minutes long 80 slides, 95% screen shots, 3 slides text animation. trying enhance download time web page. how following effect file size , download time.
1) time spent on each slide. should try reduce time spent on each slide?
2) there compressor tools compress published flash file?
3) advanced methods , tips minimize file size? (deleting unused images, jpeg quality 50%, altering color gradients, etc...)
bandwith summary- size (uncompressed) 3438 kb 6 k/s video (uncompressed) 3437 kb 6 k/s time 9:30 lowest stream broadband frames: 17115 (30 fps) resolution 790x 555

without seeing source, have getting 80 slides 10-minute demo , having compress 3.4mb pretty reasonable as-is.
the time spent on 1 slide doesn't impact size of swf -- display 1/10th of second or 10 seconds , ought have same results: has downloaded 1 way or other...and once has, can show long like.
there 3rd-party flash compression tools, they're not helpful captivate output. many of tools concentrate on optimizing vector objects , animation. captivate output series of bitmap images, , captivate great job of time. own eltima software's "flash optimizer" , have tried - minor amount of space saved (if any) never outweighed degradation of bitmaps caused.
in experience, compact swf if these things:
1) avoid using full motion recording.
2) simplify desktop color scheme , eliminate desktop wallpapers before recording.
3) if bring in external bitmap images, bring them captivate 24-bit bmp files. totally uncompressed images, , captivate successful @ compressing clean images upon publishing swf.
4) set video quality property slides "standard" (not optimized or jpeg) standard practice. in event images lousy setting, try switching "optimized," publish again, , see new swf size is. if can't live file size, switch slide "jpeg," when publishing, adjust jpeg quality setting low can tolerate.
5) if use audio, female voices can compressed custom bitrate of 32kbps, 22.050khz, "encoding speed" moved way left (zero) support better-sounding outcome. kind of images have determines kind , amount of compression can use, use of music, sound effects, , female vs. male voice impact how audio compression can away with.
definitely try eliminate color gradients if can. frames per second doesn't seem impact size of swfs. keyframes (which seem set each time background image changes) seem more important. can't control number of keyframes captivate creates. thing can use fewer background images.
