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.
