To Choose DV Video Encoder Type 1 or 2 ?
DV Video Encoder Type 1 OR Type 2
When it comes to rendering video to DV format, sometimes we face a delimma of choosing between DV Video Encoder Type 1 and DV Video Encoder Type 2.
Here’s a quick answer for video makers using miniDV tape format. Choose DV Video Encoder Type 2.
If you want to know why, read the following explanation taken from microsoft site.
DV Video Encoder Type-1 Method
The native DV interleaved stream that is produced and consumed in I/O with a DV device contains DV compressed video and pulse code modulated (PCM) audio data. This single interleaved stream can be stored in an AVI file as “ivas” stream (for interleaved video/audio stream). Microsoft refers to this format as a type-1 DV AVI file.
Because the type-1format stores data as a single AVI stream, type-1 DV AVI files are not compatible with VfW. DirectShow, however, easily handles type-1 data streams by routing the streams to a DV Splitter filter that produces a DV-encoded video stream and one or more PCM audio streams for playback or subsequent processing.
DV Video Encoder Type-2 Method
Interleaved DV data can also be split into a single video stream and one to four audio streams within an AVI file. Microsoft refers to this format of storing DV data as type-2. This format has the advantage of being backward compatible with VfW, because it contains a standard video “vids” stream and at least one standard audio “auds” stream.
Notice that the type-2 file format requires a small amount of additional processing to split and multiplex the DV stream during the functions of capture and transmit to IEEE 1394 DV devices.
Don’t ask me what the above means. Just choose DV Video Encoder Type 2.
To your success!
