I just wanted to post the fruits of my labor so others could benefit. A little background first... for the past couple days I've been banging my head against the wall trying to figure out how to take the video produced from my digital camera (Casio Exilim EX-S500) and convert it to a format that Cinelerra would be able to work with the following also applies to any video downloaded from the Internet.
Casio Exilim EX-S500 Video Output: MIME type: video/x-msvideo [Video] Dimensions: 640x480 Codec: ISO MPEG-4 Framerate: 29.97 Bitrate: N/A [Audio] MS IMA ADPCM Sample rate: 22050 Hz Channels: 1 FFMPEG's take of the the Casio AVI file: Input #0, avi, from 'CIMG2687.AVI': Duration: 00:00:04.2, start: 0.000000, bitrate: 2106 kb/s Stream #0.0: Video: mpeg4, yuv420p, 640x480, 29.97 fps(r) Stream #0.1: Audio: adpcm_ima_wav, 22050 Hz, mono, 88 kb/s What works: #1 [MPEG-2 DVD-NTSC] ffmpeg -i CIMG2687.AVI -target ntsc-dvd -aspect 4:3 movie.mpg (must use NTSC format setting in Cinelerra) #2 [MPEG-2 DVD 640x480] ffmpeg -i CIMG2687.AVI -target dvd -s 640x480 -ac 2 movie.mpg (takes care of audio and video format - MPEG-2 + 48KHz PCM audio) #3 [DV] Files converted to DV with Kino work (must use NTSC format setting in Cinelerra) #4 [MJPEG with PCM] mencoder CIMG2687.AVI -ovc lavc-lavcopts vcodec=mjpeg -oac pcm -o movie.avi (works, but the video was choppy when played back) My favorite solution: Use ffmpeg -target dvd function (handles all the video and audio settings for you), add a second audio channel to convert the audio from mono to stereo, and set the scale to 640x480 (else it will default to 720x480). SIDE NOTE: I wish the documentation on http://cvs.cinelerra.org/docs/split_manual_en/cinelerra_cv_manual_en_5.html#SEC73 had this information available in a chart or something -- would have saved me hours of trial and error. Also, STAY AWAY from trying to load MPEG-4 DivX/Xvid/H.264 files into Cinelerra. They just doesn't play nice! Now I'd like to see... What have you come up with that works using ffmpeg, mencoder, avidemux?
