At this point I'm very sure that the drive speed is actually the bottleneck. I'm not sure why it's so slow tho. Splitting it is an interesting idea, maybe it's also possible to tell ffmpeg to only extract every 6th frame and start at a different frame for each of the 6 cores.

But we do have to choose, there's only so much money available. Of course nuclear is better than fossil fuels but there's just no point in wasting all that money on it that could have instead gone into renewables. I also don't get your argument about the quantity of energy needed because that was exactly my point, with a set amount of money, you get way more energy out of renewables than fossil fuels. And building renewables is way faster than building nuclear power plants. It takes 15 years, at best, to build a nuclear power plant.

Here's a chart of the cost of different energy sources from wikipedia:

Here's how Germany is doing after shutting down all nuclear power plants.

Here you can see how fast Germany is currently building renewable energy, so apparently it is possible to it this fast.

France is a country that uses a lot of nuclear power. Here's an article that shows how expensive that is.

• Material: PLA
• Brand: GEEETECH
• Nozzle Temp: 215°C
• Nozzle size: 0.4 mm
• Retraction speed: 40 mm/s

I already tried increasing the retraction length but it didn't help. I have it at 0.5 mm now and I read online that Sovol recommends not going above that. Someone else also recommended drying the filament, so I'm going to try that. I don't know what the glassing temperature is but it's PLA, do you know what a safe temperature would be?

I'm using PLA. I could try enabling those settings but it seems more like a workaround, it would be better to find out what the underlying issue is. I also don't really know how to dial in the settings for the filament, I don't know what effect the settings have and I don't wanna waste a ton of material just randomly changing values.

I'm using PLA. How would I go about drying it?

Edit: Just saw that someone commented how to dry it by using the printer's bed.

The config I'm using has increased speed compared to the default settings. I heard about the cooling system too, I could try lowering the speed to see if it helps and if it does, I saw online that you can swap the fan for a bigger one. Which speeds would I have to lower, exactly?

It's PLA. Forgot to mention that.

Nuclear is expensice as shit tho, you can get way more energy from renewables with that money

Making it available to others as well would be the perfect solution then

Why the downvotes?

Lemmy should really add alt texts like Mastodon has

I use BTRFS with zstd compression at the default level basically everywhere and it's great. I don't notice any performance difference but I have a lot more storage.

I guess it made him look stronger or cooler or something. He'll probably also use this to say that Democrats are trying to kill him, insinuating that they don't mind killing people to achieve their goals.

I use upscayl-ncnn (basically just the cli version of Upscayl) and it doesn't support vapoursynth. I've heard of it before but I don't really know what it is or how to use it.

I don't really wanna buy another SSD just for this. I already have two SSDs in my PC, I just don't have enough storage left. All the frames are gonna be like 300gb.

I have a Ryzen 5 3600. My command was ffmpeg -i video.mp4 -threads 12 -distance 0 -effort 1 extract/%06d.jxl.

Yes, I compared it to the same frame exported as a png

Even if they use the same technique, they're entirely different algorithms and h.264 also takes information from multiple different frames, which is why the video is 1.7gb but a folder with each frame saved as a png is over 300gb.

The formats with the best compression, where it might be fine, are jpeg xl and webp, as far as I know. They're even slower tho because they're so CPU intensive and only use one thread.

Setting the png compression to 0 doesn't help because the bottleneck for png is the hard drives write speed. I already tried that.

A) I actually didn't know about this before, do you know what option I need to use in ffmpeg to set the effort?

B) I tried those but it's the same issue as with png, that the hard drive's write speed is too slow (or it's the USB 3 connection but the result is the same)

Edit: Just found out how to set the effort. Setting it to 1 is quite a bit faster but still slow at only 3.8 fps.
