  • That and more really. You could use it to do a green screen effect, but you can also use it to adjust color balance, brightness or do weirder things like swapping values between colors. It gets really crazy when you are working with full video because the time of the current frame is also available to be incorporated, so you can even do animated effects.

    Another powerful filter is the convolve filter. That allows you to apply matrix transformations, which can for example be used to apply a homography matrix and adjust a videos perspective.


  • Well for instance you can use it to apply tranparencys or other effects using the geq filter. It applies a formula to every pixel in the input and can adjust alpha, rgb values, and gamma. You can also use conditionals in your formula and have access to the current pixels location and value, so you can apply your transforms only to specific regions if you want, or do an adjustment keyed only to a specific color.




  • I ended up on .zip, the switch was mostly painless, just a couple small tech issues and having to get rid of a default block. I didn’t have any communities I managed, so not really applicable. I did consider Piefed, but I’m satisfied with Lemmy and Jerboa, and many accounts I see from piefed are superusers I don’t vibe with so it hasn’t drawn me. I would say the switch was pretty seemless and I didn’t grow super attached to lemm.ee because it wasn’t my first instance to shut down.



  • I worn in Automotive despite hating cars and believing the industry is fundamentally at fault for the state of the world currently (Leaded gasoline, micro plastics, and climate change) and is working on contributing to the death of privacy and owning things.

    There are a few different things that help me sleep at night, though I don’t sleep well in general.

    First, I have poor self image. This means both that I struggle to believe I can find work elsewhere and also that I don’t feel like I’m good at my job. You might think that would make me want to leave more and believe me I do, but it also kind of Uno reverses the act of working for them. If I think I’m bad at my job and my job is at an evil corporation, then I’m actively draining the organization of money that could be spent elsewhere.

    Second my work mostly doesn’t touch on the things that are vile and awful about the industry. I’m a programmer and my work primarily deals with displays and control interfaces. A display not coming up isn’t going to harm the industry in any meaningful way, but it will impact a person using the end product. Since that’s where most of my work lies it is easy to rationalize doing those things.

    I’m unhappy my industry exists and has done such damage to the world, but until I can find something better I’m stuck.
