This results in the file being changed, potentially losing information in the process. So our algorithms instead have to make some choices, assumptions, getting rid of similar or extraneous information. Images, audio files, video- they all have significantly less patterns. The problem is, not everything is text based, and our powerpoint example was maybe not the best, mainly because it was probably filled with images, gifs, and maybe other non-text items. Although American English is a mess, I promise it still has patterns. Languages and written text are easy to compress because they are filled with patterns. This methodology keeps all the original information in the file and is consider lossless compression - we lost no information during compression. References are cheaper because we can always refer to that location for the same value, even though you might have the same graph on 3 slides because you are trying to prove a point. 'pass by reference' day if you went through formal computer science education.

That voodoo computer magic I mentioned before I went on my quest for a pictorial metaphor is really a set of algorithms, aka encoding methods or codecs, that identify places where you can use reference instead of repetition. Make your file smaller and easier to send across the network with the information you really want to convey. We got rid of the redundant info, the spaces between the vehicles.

The person on the receiving end is able to download the zip, uncompress it (or unzip it), and they get your presentation in all the enormously huge goodness. Through voodoo computer magic your presentation goes from huge to almost manageable and you can send it as an email attachment.
Lossless video codec zip#
One of the most common ways you encounter compression is when packaging your enormous powerpoint presentation into a zip file. This won't be your most comprehensive look into video compression as there are other resources that probably do that much better. I'm probably just a set above bare minimum with video at this point. I'll admit, I've run into this topic before when working with audio files for Speech to Text (Opus, in a webm container if you are capturing from the browser), but I learned exactly the bare minimum to get results. I had a few people reach out and ask for more information about lossy and lossless compression, particularly related to videos and video codecs.
