Video scalers are designed to avoid this predicament by scaling the source video format image in whichever direction required to match the display screen resolution.
Ideally, that video scaler would also be easy to configure, have a clear menu structure, have the most common type of connectors on its inputs and output, and possess the capability for a wide range of input formats.
Verify that all the source video formats you need are managed to your satisfaction and that you have all the adjustment range you feel is appropriate for your choice of output format, such as video processing, image zoom, and aspect ratio adjustments.

  Video - Wikipedia, the free encyclopedia
Video is the technology of capturing, recording, processing, transmitting, and reconstructing moving pictures, typically using celluloid film, electronic signals, or digital media, primarily for viewing on television or computer monitors.
Video can be recorded and transmitted in various physical media: in celluloid film when recorded by mechanical cameras, in PAL or NTSC electric signals when recorded by video cameras, or in MPEG-4 or DV digital media when recorded by digital cameras.
Video resolution for 3D-video is measured in voxels (volume picture element, representing a value in three dimensional space).

 IS Video - Video FAQ   (Site not responding. Last check: 2007-10-20)
The Type C format replaced the 2 inch "Quad" systems as the premium standard of the time because it was the first to offer many of the features in a videotape format that we currently take for granted, such as: viewable still-frames, slow and fast motion, and picture in shuttle.
Video equipment designed for the production material that is not intended for television broadcast does not have to adhere to the demanding standards in image quality or equipment durability that is generally required in broadcast television.
The DV format compresses the video signal at a rate of 5:1, and the ratio of samled data are 4:1:1, which allocates 4 parts of the sample to the fl-and-white data (luminance) of the component signal, and 1 part each for both of the color portions (chrominance) of the sample of the component signal.

 Container format - Wikipedia, the free encyclopedia
A container format is a computer file format that can contain various types of data, compressed by means of standardized codecs.
Simpler container formats can contain different types of audio codecs, while more advanced container formats can support audio, video, subtitles, chapters, and meta-data (tags) - along with the synchronization information needed to play back the various streams together.
Older formats such as AVI do not support new codec features like B-frames, VBR audio, VFR natively, although the format may be "hacked" to add support, creating compatibility problems.

In the RoQ video file format, audio samples are DPCM coded and the video frames are coded using motion blocks and vector quantisation.
Information was obtained by giving known input audio samples and video frames to the RoQ encoder and analysing the resulting text output from the encoder and the RoQ file it generated.
In double buffering, two video buffers are used such that while one is being displayed, the other is being updated or rendered with new information.

 Video File Format Comparison
When dealing with video files there are several factors that need to be considered, like bit depth, frame size and frame rate as well as compression and codecs used.
For example, a 15-megabyte video might be reduced to 150 kilobytes Prior to transmission, the codec converts analog signals to digital signals and compresses the digital signals.
This is a general purpose format for exchanging multimedia data types that was defined by Microsoft and IBM during their long forgotten alliance.

 RFC 2190 (rfc2190) - RTP Payload Format for H.263 Video Streams   (Site not responding. Last check: 2007-10-20)
For every video frame, the H.263 bitstream itself is carried in the RTP payload without alteration, including the picture start code, the entire picture header, in addition to any fixed length codes and variable length codes.
For H.263 video streams, the RTP timestamp is based on a 90 kHz clock, the same as the RTP timestamp for H.261 video streams [5].
The layout of an RTP H.263 video packet is shown as: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

The format remained unchanged and was in wide use for almost 30 years until the early 80's - an impressive record that still stands and is unlikely ever to be broken.
This format was widely used by the broadcast industry into the early 1990's and remains to this day, the highest quality by far, of any of the analog formats.
Video companies being themselves deeply involved in the "Image Business", are acutely sensitive to having the most recognized name in professional hardware (sometimes at the expense of not embracing superior technology).

 Video recording formats
Some video equipment may still have RGB inputs or outputs, as converting between these two component representations is easy; see the equations at Rick Davis' digital video page (that's for NTSC, by the way -- PAL uses slightly different coefficients).
Even the formats using compression maintain the entire vertical resolution, although all the compression methods are two-dimensional and operate on the image as a whole and not on separate lines.
Note that in C format, the entire composite video signal is recorded and played back as is without splitting it to Y/C, like most composite recorders do, or limiting the bandwidth in any way.

 Choosing the best video format for your web site
You simply convert your video to a Flash format (more on that in a minute), and then you can be fairly confident that the maximum number of people can play it without having to download any additional software.
QuickTime is a container format, which means you can use any of several different codecs for compressing the software (e.g., H.264, Sorenson, etc.).
By contrast, when video is streamed then it's just spit at your computer with no regard for the integrity of the data, so you get that data much quicker, though there could be some dropouts.

 History Quadruplex EIAJ pilot tone skip field betamax ampex quad & others   (Site not responding. Last check: 2007-10-20)
Early considerations were that the format had to meet NTSC standards (the very same video specifications in use today) and had to have full 5mhz bandwidth (400 lines of resolution) as well as the capacity to support color in the future.
In the skip field format, video is recorded by only one of the two video heads, resulting in only one field being recorded.
Video was new to them and the ability of an inexpensive, easy to operate machine to record and playback anything at all, was fantastic enough in itself and simply good enough.

 Audiotek Press: Notes About The VHS Video Format
As it is impractical to physically separate the component luminance and chrominance signals on a home video cassette, both signals appear on a single "track." This prevents the use of a simple mapping between magnetization and image colour as was possible between magnetization and the simple audio waveform.
Some video recorders promote themselves as being able to engage in "Y playback on X TV." This means that the video recorder itself is able to decode the Y signal and output it as an X signal on its video channel or via its Video Out RCA jack.
Most Audiotek master video recordings before 1999 were recorded in VHS PAL SP with a hi-fi stereo soundtrack (as well as a mono-compatible linear soundtrack.) Information on the quality of a programme is recorded in the full Audiotek video catalogue.

 Video Format Conversion
The file formats also provide different mechanisms for interleaving the video and audio data within the file so that they can be processed efficiently and played, in sync, in real time.
Since the AVI and QuickTime file formats are basically control information wrapped around the audio and video data, it would seem logical that you could convert files by simply stripping off one kind of control information, and then pasting back on the same information in a different format.
Video file formats can be confusing, but converting video files and sharing them between platforms can be done, if you take care and keep things simple.

 Howstuffworks "How Video Formatting Works"
As it turns out, there are a number of ways video producers modify theatrical films for video release, and elements of these processes have sparked heated debates about maintaining artistic visions.
Video, on the other hand, stores visual information as an electronic signal that can be transmitted via radio waves, sent through coaxial cable, etc. Because of this, film and video have very different properties.
Video producers significantly change most movies from their original theatrical presentation because standard television screens have a different shape than standard movie pictures.
