Colorbars

I'm not a professional video editor, but I do work in video encoding. Sometimes I need to throw together some quick test content. This leaves me often doing the same image search for the same images every time. In an effort to save time, I decided to collect them all up in one place. That place is this website.

Static images representing colorbar test patterns.

I've used these stylistic images when video editing my own little projects.

Black Frame

Sometimes you need a 1080-sized black image because the editing software you're using doesn't natively fade to/from black.

Battery Dead

Full-screen “battery dead” graphic.

Low Battery

Corner bug for low battery, with an alpha-black background. Can be blinked on/off for more visual impact.
