Media in the Press "When I'm working, I don't feel like I have to struggle against some developer's preconception of how I should be doing things, indicative of good interface and workflow design. For those who have not looked at Media , or not looked lately, now might be a good time to give it a try.
The program does many things in the simplest and most direct manner, with some functions accomplished in a single click instead of two or three on other NLEs. Corrupt clips can be recovered from P2 cards , quicktime.

Fixing the video is usually done without problem. Quality is excellent. Audio requires a bit more of work: 2, 4, 6 or as many as 8 audio channels can be found. The audio format is usually PCM , Hz, 16 bits.

Sometimes, audio is encoded as 24 bits integer in Long Play mode is not available. Because of the wider track and track pitch, DVCAM has the ability to do a frame-accurate insert edit, while regular DV may vary by a few frames on each edit compared to the preview. This has the effect of cutting total record time of any given storage medium in half.
Chroma resolution is improved by using chroma subsampling. Like HDV-SD , it was meant as an intermediate format during the transition time from standard definition to high definition video. Similar horizontal downsampling is used in many other HD formats. It uses a similar compression scheme but at higher bitrate.
Tape-based DV variants, except for DVCPRO Progressive, do not support native progressive recording, therefore progressively acquired video is recorded within interlaced video stream using pulldown. The same technique is used in television industry to broadcast movies. Progressive video can be recorded with interlaced delivery in mind, in which case high-frequency information between fields is blended to suppress interline twitter.

If the goal is progressive-scan distribution like Web videos , progressive-scan DVD-video or filmout , then no filtering is applied. Video recorded with pulldown and no vertical filtering is conceptually identical to progressive segmented frame.

Consumer-grade DV camcorders capable of progressive recording usually offer only pulldown scheme because of its simplicity. Such a video can be edited as either interlaced or progressive and does not require additional processing aside of treating every pair of fields as one complete frame.

Frame repeating is similar to field repeating used in interlaced video, and is also called pulldown sometimes. DV was originally designed for recording onto magnetic tape. Tape is enclosed into videocassette of four different sizes: small, medium, large and extra-large. Small cassettes, also known as S-size or MiniDV cassettes, had been intended for amateur use, but have become accepted in professional productions as well. Large or L-size cassettes are accepted by most standalone DV tape recorders and are used in many shoulder-mount camcorders.
These cassettes are not widespread, and only two models of standalone Panasonic tape recorders can accept them. Technically, any DV cassette can record any variant of DV video. Early Hi8 ME tape was plagued with excessive dropouts, which forced many shooters to switch to more expensive MP tape. After the technology improved, the dropout rate was greatly reduced, nevertheless Panasonic deemed ME formulation not robust enough for professional use.
Tape-based Panasonic camcorders do not use small DV cassettes, effectively preventing use of ME tape. With proliferation of tapeless camcorder video recording, DV video can be recorded on optical discs , solid state flash memory cards and hard disk drives and used as computer files. In particular:.
