Reduce file size, reduce duration and maintain the original frames & quality. Bonus, the process is even faster than traditional editing, as you don't have to wait for the video to be re-encoded!

Spatial vs. Temporal Compression

Spatial (Intraframe) compression is applied to each video frame independently, treating each frame as a stand-alone image. This is the type of compression leveraged by high-end video production facilities as it provides superior picture quality and efficiencies in the editing process. Every frame is a key frame.

Not cool, but what’s worse than that? When they don’t know what the hell they're talking about, then convince the majority that they do. This is the case for a lot of Digital CCTV (DCCTV) manufacturers.

Here’s why you don’t.
