my tips and thoughts as a developer

Alpha Channels in Video

I looked around for any concrete information about including alpha channels (transparency) in video files. There's not a lot to be found easily out there, but I manages to figure out a format that works.

I just use QuickTime MOV file format with an RGBA color space, and it seems to work and be supported in pretty much any software I tested it in.

Good to know for the future, for video overlays/animations or other assets that need to be more flexible than just green screen animated videos which can have issues that this doesn't have.

Making PWA Sites

My steps to make a website able to be added to home screen, standalone with an icon.

Steps:

  1. Make or use a mobile friendly website. Don’t forget a viewport meta tag!
  2. Make an icon. Android Asset Studio is great for making simple icons quickly
  3. Generate icon sets with the 512p (or higher res) icon on something like Real Favicon Generator
  4. Add the html code and upload the icons and manifests
  5. Replace the icons in the generated manifest.json with the realfavicon generated ones if you use another generator

Blog?

So, this is cool too!

But will I use it?

Maybe.
