yeah guess rmvb is not popular...its just cuz rmvb is small 78mb rmvb = 170mb avi...
so i would prever rmvb, but its not so popular on mac anyway...
btw i find an awesome software converter
it s called : ffmpegX
its a Mac OS X GUI to ffmpeg the "hyper fast video and audio encoder" (http://ffmpeg.sourceforge.net/)
. This GUI provides quick encoding to DivX, XviD, AVC/h.264, VCD, SVCD, CVD, DVD, 3GP, DV, MP4, MP4 for iPod, MP4 H264 for Sony PSP, FLV, MOV, mp2, mp3, AAC & AC3. MPEG-2 encoding relies on mpeg2enc component from the mjpegtools package
and its FREE ^^
try to convert avi to mp4 with x264 h264 format, u can commpress 300mb avi into 90mb mp4 and the quality is still great
i dont know if there are other ormat which is better...if u already DL it please tell me is there any format better than x264 h264 mp4?
