you might want to try out avidemux. it's one of the best movie editing |
| 28 |
software around the world. it should be based on ffmpeg. also, for encoding |
| 29 |
in ffmpeg you should enable the encode use flag. the last hard masked |
| 30 |
version works like a real charm for me. versions newer need some fix since |
| 31 |
ffmpeg has moved its includes in the second half of february, so i would |
| 32 |
advise you not to use the live ffmpeg. |
| 33 |
you might want to try out the hardcoded-tables use flag that would improve |
| 34 |
by some ammount your ram use also. |
| 35 |
my ffmpeg use flags are: |
| 36 |
|
| 37 |
aac altivec amr -debug -doc ieee1394 a52 encode imlib -ipv6 mmx vorbis test |
| 38 |
theora threads truetype x264 xvid -network zlib -sdl X mp3 hardcoded-tables |
| 39 |
-bindist |
| 40 |
|
| 41 |
they work really well for me. |
