Comments |
JPEG decompression is CPU intensive and therefore very slow. *Recompress() converts JPEG AMF videos into LZ videos using an 8-bit palette. This format plays back four to five times faster than JPEG and occupies only about twice as much memory as a JPEG file (depending on the JPEG compression level). Generally, the *Recompress(1) setting is preferred, since the *Recompress(2) setting delivers only a 0% to 15% saving in memory usage and takes several times longer to convert videos. *Recompress(2) should only be used if maximum memory saving is demanded. |
