File size and frame rate defaults

[kornelski]

To avoid creating huge/wasteful GIFs, I suggest having smart defaults.

• If resolution is >= 640px wide, halve it. Videos have chroma subsampling and compression artefacts that are wasteful in GIF, so halving resolution for GIF is a good idea anyway.
• If framerate is >= 24fps, halve it. Frames cost a lot in GIF.

What do you mean by "halve it"? People expect to get the resolution/fps they chose.

I mean setting sliders in the UI to that value when the window is opened.

Instead of defaulting values set in the UI to values read directly from the video (effectively max resolution, max fps by default), default to values from the video adjusted to make more sense.

Ah ok. Yes, I agree.

I added a fix for this.

However the scale slider has a minimum value of 0.2. Should I do something about this?

If I record a fullscreen recording it will be 3360 × 2100 which means I can't make a gif smaller than 672 x 420.

Maybe define a minimum dimension and set the minimum scale dynamically based on that..?

I've made suggestion for the dimensions here #25 (comment)
