Firstly, let me say that ImageMagick is a fantastic tool for creating timelapse movies of mountain sunrises and sunsets. (I butter you up first, then I ask for your help.)
When I use "convert -delay 10 *.jpg filename.mpg", I get the following results: Warning: setting constrained_parameters_flag = 0 Encoding frame 0 ............................................................ Encoding frame 1 ............................................................ vbv_delay underflow! (decoding_time=22400.0, t_EOP=132920.6 )vbv_delay underflow: -106923 Encoding frame 2 ............................................................ vbv_delay underflow! (decoding_time=26000.0, t_EOP=140823.1 )vbv_delay underflow: -111225 . The playback of the resulting mpg exhibits different quirks depending on the player. For example, with a :21 second mpg, Quicktime 7 will stick on the first frame for :04 seconds then play the rest very choppily. Windows Media Player 10 plays very choppily and it believes the :21 second video is 1:37 (but stops after :21). VLC 0.8.6a plays smoothly and knows the proper length. Too bad for us, most people aren't viewing our MPGs with VLC. Note: encoding without the '-delay 10' results in the same underflow messages and same symptoms on playback (at a different pace, of course). So, first, is my quirky playback a result of the underflow messages I'm seeing? Two, what can I do to get rid of the quirky playback?
