Tuesday Tip #3 – Compression: Keyframes are your Friends: "
To those that are new to video compression and encoding, there may be a setting you might not know about, or are unfamiliar with if you have seen it. It’s the “keyframe” setting in many video encoding applications.
A video compression keyframe has nothing to do with an animation keyframe, so let’s get that out of the way first. When encoding video for the web, or anything that needs small files while maintaining decent visual quality, keyframes can be your secret weapon. Think of video compression keyframes as your reference frames to which all successive frames will be based on. This way, those successive frames don’t need to “recreate” the entire frame of visual data, only what has changed from the keyframe.
