Question regarding video codec royalties

Let's say I am making a video and have hundreds of gigabytes worth of footage compressed using FFV1 and need to free up drive space and so decide to start compressing some of my footage with lossy HEVC.

If I include footage compressed with lossy HEVC in the edit, but encode the final master with a royalty free codec, do I still have to pay royalties because it includes footage originally encoded with HEVC and consequently features forensic visual traces of it despite having been re-encoded?

Help finding good data compression and storage methods that can work on an old laptop as a server

hey everyone so I just got a new laptop it's not the newest but a very big upgrade from what I used to have and I have a lot of data scattered everywhere so I want to see what is the best way to deal with all the data I have

my data has been scattered all over the place scattered all over smaller USBs and hdds and it's a lot of iso files , app installers , apks , videos , images , documents , system backups and much more and the total size is around 1.6 tbs

so I was searching around and found tools like restic , xdelta3 , rmlint and btrfs but I'm not sure if that is the best approach yet

what i want is to compress the data and store duplicate files in the best and most efficient and space saving way and I want to turn my old laptop into a small server / testing environment for non systemd Linux distros

my main rig has nixos installed and I'm doing system backups and I want to be able to send them over the network to my older laptop for storage and I want the best way to organize data

I'm also learning a lot of things and learning game dev as well so the file sizes will only get bigger

the older laptop has only around 512 gb of storage but I'm planning on expanding that and installing freebsd as the server os / daily os whenever I need to use that machine and I want to self host some stuff on it as well

so if there's any better ways to deal with data or compress it and oeginize it in a better way that would be amazing plus if there's any tips on self hosting that would be amazing

and if there's any other subs you'd recommend I post in please let me know

I made an open-source archiver that beats 7-Zip and WinRAR in some of my tests

I made a small open-source archiver called DedupArc.

In my tests on game folders it compressed better than 7-Zip and WinRAR while also being noticeably faster.

It also lets you launch applications from an archive without manually extracting the whole thing first.

GitHub: https://github.com/Garyu-tt/DedupArc

Would be interesting to see how it performs on other people's data. If someone finds a case where it completely falls apart, even better.

y'all what compression software do I use for old games

okay so I have several hundreds of gigabytes of old games on my hdd that I've either used 7zip ultra using .7z on for the archived ones or NTFS lzx compression on for the active ones. what do I swap those our with for even more compression. I have a xeon 2698 v4 with 20 cores allocated for gaming and 10 others allocated for everything else via process lasso

I built a fast, privacy-focused WebP compress and resize tool that runs entirely in your browser

Hey everyone,

I got tired of shady online image compressors that upload files to unknown servers or put everything behind a paywall.

So, I built a free tool that compresses and resizes WebP images locally using client-side processing.

Why I Built This

  • Privacy first: Your images never leave your computer. Everything processes right inside your browser.

  • Fast and light: No ads, no account required, and no artificial file size limits.

Key Features

  • Drag-and-drop interface for fast workflows.

  • Custom quality slider to balance file size and image clarity.

  • Dimension scaling to fit exact pixel widths or heights.

  • Instant download for processed files.

I use it daily for optimizing website assets, and I wanted to share it with the community in case it helps others working on web performance. And since everything is processed on local device. No uploads means images compress and resize instantly.

You can try it out here: WebP Compress And Resize

I would love to hear your feedback or feature suggestions! Let me know what you think.

What price would you willingly pay for your games to be compressed?

I am a software developer and i am working on compression apps, i managed to code a game-aware compression system,
It effectively compressed a gta v installation into 80gb (30%\~) while sacrificing almost no CPU usage (2-3% of usage), and just a bit more waiting time on loading screens and only a 7% fps drop MAX.
How much would you be willing to pay for a program that could do such on any given game as a gamer?
For more questions ask below.

How to improve video quality?

I uploaded this as a 4k FFV1 MKV: https://www.youtube.com/watch?v=eDtWAsZSdjU

It looks really compressed. The file on my hard drive is completely lossless and looks beautiful. I understand that I'm not going to achieve that on YouTube but I would at least like to improve it as much as I can for subsequent uploads.

What codecs, containers, settings, etc., have worked best for you?
