#compression

I have to say that iZotope's Nectar remains incredible at cleaning up voices. I had two actors in which there was a very small amount of amplified noise. Small. But, for a guy like me, utterly unacceptable. Nectar's EQ and compression did the best job sweetening the voice and killing this minor "electric" gain than any other compression software I have.

Pour illustrer les paramètres "compression maximale" dont j'ai parlé là : sebsauvage.net/links/?s0zmfA

Illustration avec un jeu : Loophole.

Décompressé: 3,18 Go
7z "ultra" (-mx=9) : 1,33 Go
7z avec mes réglages : 0,53 Go
(Et zpaq -m4 fait un peu mieux : 0,49 Go)

Bien sûr c'est un exemple qui marche bien, le gain ne sera pas forcément aussi bon sur d'autres données.

#Compression #7zip
Comme il m'a été demandé, voici les paramètres que j'utilise désormais pour obtenir la meilleure compression avec 7-Zip.

Inconvénient :
- on passe en mono-thread (la compression prend *beaucoup* plus de temps ; la décompression sera un peu moins rapide).
- cela consomme plus de RAM (10 Go à la compression, 1 Go à la décompression).

1 Go pour la décompression ne me semble pas déraisonnable pour les machines de nos jours.

Well the thing is… that was the only thing it did. Sure I could drag and drop a picture onto that program and it would automagically add pictures to the website… one… at… a… time. But I was often running into situations where I wanted to modify pictures that were already added. Sometimes the program would make wrong guesses about which file format I wanted the pictures to be.

(For the love of god NEVER compress pixel-art with JPEG!!)

So I have hundreds of videos of ~1 minute recorded from my phone ~10 years ago, and they generally don’t have that great compression, nor they are stored in a modern and advanced video format.

For archiving purposes, I want to take advantage of my workstation’s mighty GPU to process them so that the quality is approximately the same, but the file size would be strongly reduced.

Nevertheless, compressing videos is terribly hard, and way more complex than compressing pictures, so I wouldn’t really know how to do this, what format to use, what codec, what bitrate, what parameters to keep an eye on, etc.

I don’t care if the compression takes a lot of time, I just want smaller but good looking videos.

Any tips? (Links to guides and tutorials are ok too)

Also, unfortunately I am forced to use Windows for this (don’t ask me why 🫠), but I know nothing about Windows because I hate it. Practical software suggestions are very much welcome, too!
