How does my very first edited video (using Shotcut freeware) look?

Isn't the mp4 composed of a series of bitmaps? I don't know. That's why I asked! A bitmap defines a grid of pixels. If you paint black over a rectangle then those pixels are black. They can't be two things. It's not like spraypainting. Great. That's what I want to hear. The only thing I wanted in the video was privacy. The rest was easy. A PNG is just a compressed bitmap with an alpha channel option, which means one can specify a degree of blending with the background when painting the image in order to give an effect of transparency. There are no layers. Didn't we talk about this recently? Someone was asking about image layers. Images don't have layers. Graphic editors can sometimes allow working with layers, and they can save that data in their own formats. But that's not an image with layers. It's a record of digital edits. That function led someone to think that image formats have layers. They do not. A raster image is a bitmap. That's it. PDN has such layers. But not PNG. |
