Something important about all DVD

Here I would like to say something important about all DVD

DV stands for Digital Video
- video captured to a PC from a digital camcorder. [/b]
There are two methods of storing DV video data, that is, type-1 and type-2.

Both are stored usually in AVI files. Any DV stored as type-1 cannot be used with VfW-based editors.

:) Microsoft provides DV encoder and decoder filters for DirectShow only, and will not provide support for encoding or decoding DV video data for VfW.

DV 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.

:help: 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-1 format stores data as a single AVI stream, type-1 DV AVI files are not compatible with VfW.

DirectShow, :help: 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 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 stream and at least one standard audio stream.

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.

miniDV is the most popular digital camcorder format at the moment.

miniDV is a video cassette designed for use in miniDV digital camcorders.

The picture quality of digital video (DV) recorded on a miniDV cassette is basically identical or better to the quality of DV recorded on a Hi8 or 8mm cassette by a Digital8 camcorder.

:help: miniDV can have up to 530 lines of video resolution for some camcorder models. However, miniDV tapes are smaller which allows for smaller camcorders.

miniDV tapes :whistling: are available in lengths of 30 and 60 minutes (plus, recording in LP mode lets you extend total recording time with a 60-minute tape to 90 minutes).

DVD stands for Digital Versatile Disc.

DVD is essentially a bigger, faster CD that can hold cinema-like video, better-than-CD audio, and computer data. View How to rip DVD to MPEG, PSP, iPod, MP4, DivX, AVI, WMV, 3GP, RM, MOV, MP3, WAV, AAC, OGG, WMA etc :)

DVD-10 :upset:
DVD-10 is a double sided single layer DVD.
Video DVD, DVD-R/W and DVD+R/W support this format. Effectively this means that DVD-10 is a dual-sided DVD-5 and can hold 8.75 gigabytes of data with 4.38 gigabytes on each side.

Two-sided discs need to be flipped over in order to access the other data side. Unfortunately many blank DVD media advertisers mislead customers to believe that these discs are actually blank DVD-9 discs in hope that they could copy their dual-layer discs directly to blank discs.

DVD-18 is a double sided dual layer DVD
:blink: which can fit up to 17 GB or 15.9 computer GB which some commercial video DVDs are using today (a DVD-18 is basicly four pressed plastic DVD-5s pressed together, they are not burned). Video DVD supports this format but DVD-R/W and DVD+R/W does not support this format.


DVD-5 is a single sided single layer DVD that stores up
to about 4.7 GB = 4 700 000 000 bytes and that is 4.38 computer GigaBytes where 1 kilobyte is 1024 bytes(4 700 000 000B/1024 = about 4 589 843KB/1024 = about 4485MB/1024 = about 4.38GB) .

:upset: Video DVD, DVD-R/W and DVD+R/W supports this format. Often referred to as "single sided, single layer".

DVD-9 :)
DVD-9 is a single sided dual layer DVD which can fit up to 8.5 GB or 7.95 computer
GB which many commercial video DVDs are using today (a DVD-9 is basicly two pressed plastic DVD-5s pressed together, they are not burned).

Video DVD supports this format but DVD-R/W and DVD+R/W does not support this format.
