Green Screen Studios: Magic

By Phil Guye

Green Screen Studios is a cheap video and filmmaking method in which two frames are melded into one. It is also ordinarily called Chroma key or sometimes color keying. A notable use is in TV weather bulletins where the weather person looks to be standing in front of a giant graphic display. What happens actually is that the weather person stands in front of a blank Green Screen Studios. Different graphic displays are then digitally added to the blank green portions to finish the illusion.

Green is a preferential color because it's so different from human skin color that good separation is attained. It's also the color to which digital cameras are most sensitive. The other available color blue is less advantageous because it's a common color in both masculine and feminine clothing and needs brighter lighting. Lots of the more modern Star Wars films make intensive use of color keying strategies. Green Screen Studios is also far less expensive than having your characters or props in front of an actual projection or television screen.

Any project that involves green screen production should require the same kind of homework in sourcing an appropriate Green Screen Studios as a sound stage for a picture or a recording studio for music. The taping or filming of your characters or your props in front of a Green Screen Studios and the subsequent keying out of the green background needs skilled and accomplished technicians.

It is accepted that cost will be a vital consideration and that Green Screen Studios will charge primarily based on the size and the standard of the gear and the talents of their technicians. This has got to be balanced out against the fact that cheap facilities might be fatal for the standard of your project. Conversely, pricey facilities could be a waste of money given the production that you have in mind. A good Green Screen Studios will be offering such conveniences as adequate stage size, lighting, green rooms and air conditioning. A three wall cyclorama is a bonus if your project involves tons of movement by the characters. Other key concerns would be privacy, comfort and satisfactory power availability.

In selecting the right Green Screen Studios you need to be certain the color is totally even and the surface fully flat. The screen must also have the correct dimensions. It is generally recommended that you go through each shot you plan and then measure the screen area so that you have the right dimensions. Allow for a little extra in case you must widen or frame the shot more than you had envisaged. Inspect the area on each side of the screen to ensure that there is sufficient space to place your lights. Finally, get the maximum possible space between your characters or props and the screen itself. This will make the job of lighting a whole lot less complicated.

Movies And MP3

Movies and MP3 files are already compressed with near maximum capacity. Repacking them would just create larger files and increase decompression time. Ripped movies are still packaged due to the large file size, but compression is disallowed and the RAR format is used only as a container. Because of this, modern playback software can easily play a release directly from the packaged files, and even stream it as the release is downloaded (if the network is fast enough).

MP3 and music video releases are an exception in that they are not packaged into a single archive like almost all other sections. These releases have content that is not further compressible without loss of quality, but also have small enough files that they can be transferred reliably without breaking them up. Since these releases rarely have large numbers of files, leaving them unpackaged is more convenient and allows for easier scripting. For example, scripts can read ID3 information from MP3s and sort releases based on those contents.
