I have closed the forums to new postings because there was not enough discussion, I answered nearly all the questions, and I no longer work on Kino. Please use the forums provided by your Linux distribution. Meanwhile, I will leave this open in read-only mode to serve as a knowledge base.

8, What is the difference between type1 and type2 DV AVI f
Posted by ddennedy on Thu Jan-01-70 12:00 AM
AVI files may contain multiple streams. Typically, they include one video and one audio stream. The native DV stream format already includes the audio interleaved into its video stream. A type 1 DV AVI file only includes one DV video stream where the audio must be extracted from the DV video stream. A type 2 DV AVI file includes a separate audio stream in addition to the audio data already interleaved in the DV video stream. Therefore, the type 2 DV AVI file is redundant and consumes more space.

Most Linux AVI players and utilities (mplayer, avifile, mjpegtools, transcode, etc.) only understand type 2 DV AVI files. Also, Video for Windows only understands type 2 DV AVIs. Current versions of Windows DirectShow do support type 1 DV, but not all Windows applications consistently support it.
