ffmpeg2theora configuration
Posted: Wed Jan 11, 2006 8:35 pm
I am doing a bunch of video emails and I am recording them with my digital camera, and then I use ffmpeg2theora to rapidly compress the video. However I dont get a perfect configuration since the audio doesnt sync with the video.
The help file says the f0ll0wing:
I wonder if the niceness will mean the sm00thing between the audi0 up0n vide0. Any help?
