There dont seem to be that many settings for flash video encoder, compared to other video codecs.
Ive just had my first go with it. Heres 2 sample files, there may be room for improvement in quality but the only options to play with are bitrate, framerate, resolution and keyframes. These are the same footage as my previous HDV tests with H264. They are scaled down footage from a Sony HDR-HC1. Its not the worlds greatest test clips because there isnt enough variation in footage and the camera pans wont look smooth unless I use 50fps. 960x540 25fps 2000kbits/sec: http://www.unquack.com/sunflower.html 320x240 25fps 600kbits/sec: http://www.unquack.com/sunflower320.html The following are errors on my part sue to rushing and should not be interpreted as problems inherent to flash: I think I probably included audio when there isnt any audio, so filesizes slightly larger than they should be. The aspect ration for the 320x240 one is all messed up because its widescreen footage but not widescreen res. I didnt mess around with the player options much so the semi-transparent playback bar is annoyingly over the top of the video. Quality seems ok to me, seems worse on sertain frames, macroblocks become visible sometimes, dunno really thats where my knowledge ends. Judge for yourselves. I used the latest flash video format so I presume you need flash player 8 to see the above. Done on the Mac but I assume windows results should be much the same. As to why you have not got good results, need to see a sample from you to see in what way it is bad. Possible reasons would be if for some reason it didnt like that particular resolution you used, or if your intermediate codec choice wasnt as good as it sounded. The intermediate file was 110MB, but how long is the footage in question? What quicktime codec did you render the intermediate version with? Depending on your circumstances try to avoid using an intermediate file at all. If youve made edits in imovie, maybe render it back out to a dv file. Flash encoder export stuff is available from within quicktime. Its also possible to look inside imovie files (right click and 'show package contents') and see the source .dv files, which can then be loaded into quicktime, if that is applicable to you. Or maybe it might even be the case that flash export is available from within imovie, havent tried.
