What you NEED to Know Before Touching a Video File

Hanging out in subtitling and video re-editing communities, I see my fair share of novice video editors and video encoders, and see plenty of them make the classic beginner mistakes when it comes to working with videos. A man can only read "Use Handbrake to convert your mkv to an mp4 :)" so many times before losing it, so I am writing this article to channel the resulting psychic damage into something productive.

If you are new to working with videos (or, let's face it, even if you aren't), please read through this guide to avoid making mistakes that can cost you lots of computing power, storage space, or video quality.

(* Inlining for the λ-calculus, implemented in tagless final style. This seems
 * like it _must_ be related to Normalization By Evaluation (see eg [1,2]),
 * since they both amount to β-reduction (plus η-expansion in extensional NBE),
 * and the techniques have a similar "flavor", but I don't immediately see a
 * formal connection.

// A common redux pattern when dealing with async functions is to use thunk.
// This usually means your action returns a new function instead of an action object,
// and the thunk middleware will make it all work. Example:
const asyncAction = () => dispatch => setTimeout(() => dispatch(someOtherAction()), 10000);

// Now: maybe that async stuff going on is calling some API which you don't want to overload
// with request, and that's what debounce is for.
// This is an example of a debounced function which will only be calleable once every second.
import { debounce } from 'lodash';
const debouncedFn = debounce(() => callApi(), 1000, { leading: true, trailing: false });
