How quickly check banner size

FAST-SIZE-OPTIMIZATION (save your time first):

>70% projects have the same problem – not optimized images (bitmaps).

1. Check “Compress movie” in publish settings (Basic step)
   1. To avoid this situation – use banner templates
      1. Banner template basics
      2. How to create own template
2. Pictures optimization (1-2-3-…)
   1. Arrange images in library
   2. Control compression level for each image separately (from library)
      1. JPG compression
      2. lossless (GIF/PNG) compression
   3. Try to find maximum quality and size compromise
   4. Reimport different bitmap format (JPG/PNG24/PNG8/GIF)
      1. Difference between these formats
      2. Photo for JPG
      3. “Flat colors” for GIF/PNG8
      4. Transparent photo for PNG24
      5. Transparent small photo/flat colors for GIF/PNG8
3. Check file size report (analyze)
   1. Always re-check size report
   2. Check duplicated images
   3. Check re-sized images

10. Check metadata (do not include XMP metadata)
11. Check sounds compression
12. Check video compression
13. Use Vector vs Bitmap
14. Use Bitmap vs Vector
15. Use Vector + Bitmap smart tactics
