Generally speaking, tapeless solutions are preferable for a modern HD workflow. Additionally, some offer storage of HD video with less compression than their tape-based counterparts. These solutions can speed up the process of loading material into the computer. Some use hard drives built into the cameras, whereas others favor removable storage. Manufacturers have approached tapeless acquisition in different ways. These limitations have been largely responsible for the increasing popularity of “tapeless” cameras. This has the effect of increasing contrast in the edges but will destroy subtle edge detail. Most consumer (and even prosumer) cameras have a sharpening filter that is turned on by default. While accessing the camera settings, turn off sharpening as well. Double-check to make sure that the videographer has turned off these settings or you will waste time trying to fix the footage. If any of these settings are on, the footage you are trying to key will constantly change as your model moves.Įven if you’ve hired a professional videographer, don’t assume that these options have been turned off. When shooting chroma key footage, make sure all the Auto settings on your camera-auto exposure, auto-white balance, and auto-focus-are turned off. Another drawback is that loading tape is a real-time process it takes at least one hour to load an hour of source material. It also must compress the footage further to store the acquired information. It does have its drawbacks, though, because it requires hardware for playback and loading of the footage into a computer.

The use of tape has been the traditional approach and a cheap way to archive footage for cameras. Choosing a progressive format is highly desirable because it produces a clearer image that will work better for chroma keying tasks and will play back smoother on modern displays.

This means the camera records full frames instead of interlaced fields. Cameras are now readily available to shoot video using progressive formats.
This approach is ideal for CRT displays but produces jagged looking footage on other display types (especially computer displays).įortunately, video technology has evolved. The process then repeats for the second half of the image. When this interlaced process is used, half the image loads onto the CRT display from the top-left corner to the bottom-right corner.
Every camera shooting 720 will offer progressive frame rates some cameras shooting 1080 will do the same.įor better appearance on these tube-based devices, the image was split into fields. If you’re shooting 1080, be sure to choose a camera that supports progressive acquisition. Most cameras shooting 1080 do so with an interlaced approach.

When shooting HD, the 720P format is the most common for progressive video. The footage of many consumer-grade cameras is heavily compressed to save on the costs associated with the storage of footage. Unfortunately, these cameras may not be the best for keying. Consumer-grade, high-definition video cameras can be found at prices below $1,000 US. Video cameras have become significantly more affordable in recent years. With this in mind, let’s explore effective techniques for creating footage.

While software tools are fairly forgiving of poorly shot footage, the most professional results start with well-executed acquisition. Successful use of chroma (or color) key requires properly acquired footage. The popularity of chroma key technology has grown immensely, bringing the technology and tools within reach of most content creators. This technology is hardly new, making its first appearance at RKO Radio Pictures in the 1930s. By shooting elements against a blue or green screen, you can easily remove the background. One common technique you can use for video footage is chroma key technology. You can create alpha channels in several ways.
The original footage is used to generate a matte file, which can be stored with the layer for export as an alpha channel or can be used to composite over a different background layer in After Effects or Flash.
