Use less memory. Faster to run. Simpler cross-compilation. That’s it.
The crate has been audited too, neat!

🗜️ #compression #7zip
Pour illustrer les paramètres "compression maximale" dont j'ai parlé là : https://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.
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!
