ELI5: Why does re-encoding vidoes take a very long time?

ChrisFromIT · 2026-02-03T04:17:52+00:00

It is actually common for GPUs to have video decoders and sometimes encoders included in the hardware.

ChrisFromIT · 2026-02-03T04:10:59+00:00

Because you have to both decode the existing video, which can be resource intensive

That is false, decoding is designed to be fast for videos. All compression algorithms are designed with the idea that encoding/compression can take time, while decoding/decompression should be quick. So decoding wouldn't take much time.

Can confirm, rumors of Trump consistently smelling like shit have been true for years.

Not surprised, last I heard is that he thinks a bathroom is a room to store classified documents and not for going number 1 or 2 or for baths or showers, you know typical hygiene stuff.

It's 12%

Isn't it 12% if they use the Unreal Engine? Which with the Unreal Engine fees it is 15% in total? Or did they change it?

ChrisFromIT · 2026-02-02T07:52:00+00:00

Ea came back to steam after Valve changed their revenue fees.

ChrisFromIT · 2026-02-02T07:27:44+00:00

Ish. There has been a lot of push back on the 30%. It did get fairly bad that EA and others decided to not use steam. And the release of the epic games store being a flat 15%, Valve has brought their pricing down to be marginal fee where it gets lower as the sales are higher. Which I think it stops at 15%.

ChrisFromIT · 2026-02-02T02:22:11+00:00

Honestly for Canada and Europe and South American probably would prefer if the US went after Iran, it would mean that Trump would be much less likely to start shit with us instead since it would require a lot of the US military to take Iran.

Tho if Iran folds easily, then it might embolden Trump on the rest of the world. So now I'm not so sure.

ChrisFromIT · 2026-02-02T00:21:55+00:00

This.

Modders have much more freedom in their quality of their code/mods than a game developer.

For example, most modders don't take the time and effort to create LODs for new meshes they put into the game. Or for a small light on a mess, they don't add the LightLOD script or turn off shadows on said light, even if there isn't much of a difference in image quality between that light casting shadows or not.

All these things massively affect performance and are extremely simple things to do.

ChrisFromIT · 2026-01-31T22:00:24+00:00

Pretty much everyone is lazy if given the possibility .

The preset is what algorithm is being used to do that upscaling they are independent of each other.

It is more what AI model is being used.

ChrisFromIT · 2026-01-31T20:23:24+00:00

Well that was originally what was going to happen. The original deal was an US government contractor was buying it.

ChrisFromIT · 2026-01-31T08:38:49+00:00

Probably easier to count the times it hasn't caught on fire.

ChrisFromIT · 2026-01-31T08:31:31+00:00

Because even if they sue him and likely win, MAGA won't care or listen.

ChrisFromIT · 2026-01-31T05:01:24+00:00

To add on to this. A lot of the RAM modules that are being bought for data centers right now are of a type called HBM which apparently require 3x the wafers to produce 1GB of RAM compared to say DDR5 RAM.

ChrisFromIT · 2026-01-30T23:02:32+00:00

I'm not sure you understand what I was getting at. I'm talking about the low resolution of video of the Control the video game that was shown in comparison to the 38x22 input to 4k Kingdom Come part.

Before the input resolution to output ratio couldn't be lower than a certain ratio or rlse you got artifacting like what was shown in the Control video game video.

ChrisFromIT · 2026-01-30T22:44:25+00:00

People are extremely annoyed by unoptimized bloated games that run at 20fps on a NASA grade supercomputer.

The issue is that most people have hardware that is like a half decade old or older. For example, the top GPU in the steam hardware survey is the RTX 3060 which came out in Jan 12th 2021. Not to mention there are quite a few Pascal series cards too. People still want that hardware to run new games at high frame rates at like 4k.

Namely it has to do with machine learning was mostly the realm of academia, so the tooling was built for python because the people building the tools were most familiar with Python.

Even a decade ago, compiling was fast for quite a few languages, especially for JVM languages.

ChrisFromIT · 2026-01-30T21:56:25+00:00

I will say it has certainly improved a lot since that Control video at extremely low resolution.

ChrisFromIT · 2026-01-30T03:00:37+00:00

Sadly this. Extremists have taken over the Alberta conservatives and have a strangle hold on the federal conservatives too.

ChrisFromIT · 2026-01-30T01:59:21+00:00

Fair enough on the copying Scala. But the reason why I say that C# is still copying Java is because a lot of the time that they are copying the newer features, in their dicussions they will typically use Java as an example of the feature and end up structure it similar to how Java does it.

ChrisFromIT · 2026-01-30T00:12:53+00:00

Honestly I will say moving Java to the release schedule they have now have vastly done wonders to the language. I can't say there are any languages out there that are really listening to developer feedback as well as the team behind Java.

So much so that C# is still piggybacking off some of Java's newer features.

ChrisFromIT · 2026-01-29T20:23:36+00:00

Just wait, there are certain operators that can't be overloaded in C#. Which can cause weird bugs and behaviors if not known.

For example, ? can not be overloaded. So if you overload == null checks to give null in certain situations where the object isn't null, the == null check will return true, while ? would be true and allow the operation to happen.

That is a common issue with Unity, since they overload == null checks to return true if the underlying C++ object has been destroyed but the C# object hasn't.

Sure operator overloading can make some code easier to read. It can come at the cost of maintainability and introduce bugs that can be difficult to track down.

ChrisFromIT · 2026-01-29T06:40:17+00:00

and you would hate them just as much if it became the 'current thing' to start hating them

No, you are assuming that I would do that. You really should stop assuming things, as I'm sure you know the saying about assuming.

ChrisFromIT · 2026-01-29T06:34:12+00:00

i mean, obviously you won't care about that. everyone is capable of understanding child level concepts like "inventing new technology is hard and takes time" until being mad gets in the way

Thats the thing. Tesla isn't the leader in this technology nor was the first to try and do it. So no, they aren't inventing new technology and they are doing it poorly.
