FLASH banner size optimization tactics
Situation: You have flash banner 728×90 Leaderboard current size=50kb, but size limit = 30kb. Usual problem ;)
Objective: minus 20kbs… OK read bellow :)
FAST-SIZE-OPTIMIZATION (save your time first):
>70% projects have the same problem – not optimized images (bitmaps).
- Check “Compress movie” in publish settings (Basic step)
- Pictures optimization (1-2-3-…)
- Arrange images in library
- Control compression level for each image separately (from library)
- JPG compression
- lossless (GIF/PNG) compression
- Try to find maximum quality and size compromise
- Reimport different bitmap format (JPG/PNG24/PNG8/GIF)
- Difference between these formats
- Photo for JPG
- “Flat colors” for GIF/PNG8
- Transparent photo for PNG24
- Transparent small photo/flat colors for GIF/PNG8
- Check file size report (analyze)
- Always re-check size report
- Check duplicated images
- Check re-sized images
COMPLEX-SIZE-OPTIMIZATION:
- Check “Compress movie” in publish settings (Basic step)
- To avoid this situation – use banner templates
- Pictures optimization (fastest tactics)
- for JPG
- for PNG24
- for GIF
- use PNG8 vs GIF
- Check file size report (analyze)
- Check graphic symbols
- Check complex animation
- Check complex vector shapes
- Too many corners/curves
- Use Modify->Shape->Optimize
- Check fonts
- Some fonts utilizes too much space
- Avoid complex fonts/artistic fonts
- Use bitmap or Braked to Vector fonts
- If it’s possible – use one type (not bold, italic,extra-bold)
- Check embedded fonts
- Check duplicated content (symbols, graphics, bitmaps,…)
- Check metadata (do not include XMP metadata)
- Check sounds compression
- Check video compression
- Use Vector vs Bitmap
- Use Bitmap vs Vector
- Use Vector + Bitmap smart tactics
