video properties that affect encoding
-color/movement
-edits/transitions/effects
-frame rate
-display size
-sound ranges
-interlacing
-image quality
-smoothness of playback
-audio quality
-transitions/effects
IMPROVING ENCODED VIDEO QUALITY
-2 pass vs. single-pass encoding
-preprocessing filters
-advanced compression settings
-de-interlacing
-keyframes — not like Flash — snapshot of video which subsequent frames use as basis for compression
-smaller display size — 320 x 240 is about as small as you should need to go
-dropping frame rates — the fewer frames, the more room for detail in each frame
3RD PARTY SOFTWARE
-Flash video encoder is okay, but not great
-Sorensen Squeeze is GREAT
-ON2 FLIX is really good too
CODECS
-Spark Pro
-On2 VP6 Pro
-Squeeze Pro
