Video tab gives you the ability to reduce video bitrate and ratio.
- Compress video checkbox
turns video optimization on\off.
- Bitrate slider
lets you specify video bitrate value in the resulting SWF file. Bitrate is the number of bits per given time interval (usually per second), used as a measure of information flow. The higher the bitrate is, the higher video quality will be generated in the output file (however, you can’t obtain video quality better than the original one). Video bitrate value is ranged from 10 to 200 kBps. Make it smaller to reduce your SWF file size.
- Ratio option
allows you to define the proportion of the resulting video size (width and height) to the original one. The higher proportion is (slider moves to right hand side), the lower quality of the resulting move will be generated. So this is a kind of compression level, the higher it is, the smaller the resulting file will be.
Note, that if you would like to optimize embedded video without modifying frame size, please, set “Ratio” value into zero and customize “Bitrate” option.
