Minimum Kbs - Maximum quality!

• Fast method: optimization in flash
• Normal method: optimization in photoshop + import to flash

Fast vs Normal – You can try fast optimization before normal, sometimes quality result is the same. 

Fast optimization in flash

brutal force optimization – try first, then think :)

1. Go to library window (shortcut: CTRL+L)

2. Choose Bitmap object (JPG or PNG or GIF)

3. Double click on bitmap – Opens window with options

4. Switch to Custom and set quality rate (0-100). Try 30-50 first.

5. Test Bitmap Size and visual quality (press TEST button), check size, check visual quality

6. If quality is OK, try to reduce size again (type lower custom-quality)

7. If quality is OK press OK button, and try the same optimization steps to next bitmap

8. Re-export SWF and check new size.

9. If overall bitmap quality (during animation) is OK and new size is OK too – work finished. Else try Normal optimization in photoshop

Attention – Adobe Flash CS4 has OPTIMIZATION BUGS. >>>
After bitmap optimization try re-export SWF file and run it. If bitmaps became flickering/disappearing, you have to close FLA file then re-open it and export SWF again. >>>

Normal optimization in photoshop

Saving bitmap file : Adobe photoshop -> File -> Save for WEB (Alt+Shift+Ctrl+S)

1. Save for WEB window view

2. Try optimise

• JPEG (type)
• Quality (0-100) 
• Optimized
• You can try blur (higher blur = lower quality, lower size)
• Set metadata to None (no metadata = lower file size)
