The way the
images are encoded in SWF is very similar to PNG (in that a zlib-based, lossless
-compression algorithm is used). Under special circumstances, when the image
-is 32 bpp with alpha information, it is converted to (lossy) jpeg compression
-though, to preserve the alpha, which can't be encoded in any other way in the SWF.
+compression algorithm is used).
-r, --rate <framerate>
Set movie framerate (frames per second)
-o, --output <filename>
Set name for SWF output file.
Explicitly specify output file. (Otherwise, output will go to stdout / output.swf)
+-z --zlib <zlib>
+ Enable Flash 6 (MX) Zlib Compression
+ Use Flash MX (SWF 6) Zlib encoding for the output. The resulting SWF will be
+ smaller, but not playable in Flash Plugins of Version 5 and below.
-X, --pixel <width>
Force movie width to <width> (default: autodetect)
-Y, --pixel <height>
