Record Your Video Project

To optimize your video for encoding and compression, follow a few simple rules

when you record your video projects:

■

Move in for close-ups; zoom, tilt, or pan slowly, if at all. Rapid movements do

not digitize well.

■

Film your subject as closely as possible, with occasional medium-distance shots

for variety. Avoid long-distance shots, especially with rapidly-moving subjects.

■

When possible, frame your subjects against solid-colored, unchanging

backgrounds. This approach digitizes and compresses well.

■

Keep your film clips as short as possible, within reason. Record continuous

video sequences that can be digitized later and edited into a single, continuous

movie file.

■

Avoid recording at slow tape speeds. Slower tape speeds produce grainier

source video.

■

When using Hi-8, use 60-minute tape. The 120-minute tapes are 25% thinner

and may break.

■

Use a tripod. Unsteady camera movements do not digitize well.

■

Use the dominant light source in a mixed lighting environment to manually

calibrate your camera’s white balance control.

■

Use a microphone positioned close to your speaker or audio source. Avoid

using the video camera microphone unless there are no other sound sources in

the room.

■

Always wear headphones if you are capturing audio with your video. This

allows you to monitor the audio input as it’s being recorded.
