"8K video recording" - does anyone really need this? Seems like for negligible gain in quality people are pushed to sacrifice their storage & battery, and so up

"8K video recording" - does anyone really need this? Seems like for negligible gain in quality people are pushed to sacrifice their storage & battery, and so upgrade their hardware sooner...
- lightedman 2y agoI need more than 8K. I'm working at microscopic levels when I study minerals, I need as much resolution as I can possibly get, to the limit of optical diffraction.
- kstrauser 2y agoAre you actually recording movies of them though? Honest question. I hope I learn something about studying minerals!
- lightedman 2y agoYes. I do record videos for research purposes. Watching how a crystal reacts to various forms of radiation (primarily various bands of UV) gives me an idea of what impurities it might contain, or clues to composition from known emission spectra. That's recorded simultaneously through OBS with my voice doing a voiceover as I perform irradiation of the sample. Mineral goes into modified integrated sphere, sphere gets sealed, sample is illuminated, study begins.
- kstrauser 2y agoHuh! That sounds fascinating. I'd love to see something like that.
- lightedman 2y agoSome times I do live broadcasts for a group of hobbyists and degree-holding geologists. the bandwidth to do compressed 16K already exists for me, just not the tooling at the moment. Trying to show something that is literally one pixel at 400x magnification at 1080p is no fun. Even a few more pixels helps.
- DrillShopper 2y agoYes, it makes post-production SO MUCH EASIER
- Pet_Ant 2y agoWell for starters 8k video lets you zoom in and crop and still get 4k in the end.
- metta2uall 2y agoI think 4k is also too much in the vast majority of cases..
- aidenn0 2y agoIt's insufficient for large theaters and barely sufficient for medium theaters. 1080p is plenty for most home theaters (though with the so-so quality of streaming, I wonder to what degree macroblocks are the new pixels)
- bloedsinnig 2y ago1080p looks different to 4k. Just because its 'plenty' doesn't mean 4k doesn't matter. And we are at 2024, i own a 4k lg oled display now for years. Why not leverage it? Just because 1080p is 'plenty'?
- OptionOfT 2y agoThe problem with 4k, which 99% of people only experience as a stream, is that it's over-compressed. A 1080p BluRay is 36 Mbit. Netflix 4k is 15 Mbit. So unless I see people mentioning the media, I am always weary of the comparison.
- scheme271 2y agoI think the studios and anyone doing video production probably would use a 8k toolchain if possible. As others have pointed out, this lets you crop and modify video while still being able to output 4k without having to upscale.
- szundi 2y agoYes, they record with higher resolutions and then the director and the operateur has greater flexibility later when they realize they need a different framing - or just fixing the cameraman's errors cutting parts of the picture out. They need the extra pixels/captured area to be able to do this.
- AlexDragusin 2y agoYou are thinking from a consumer point of view, consumer as in Jane taking videos of her cats which 8K, even 4K would be overkill. You can set your recording device to record in 720p or 1080p and so on to suit the purpose. For commercial purposes it's another story and it makes sense to consider shooting in 8K if possible, thus the option should exist.
- bloedsinnig 2y agoYes why not? Different use cases exist: Record 8k text and you could zoom in and read things. Record 8k and crop withot quality loss or 'zoom' in Does everyone need this? Probably not but we are on hn not at a coffee party
- HPsquared 2y ago8K is important for VR video; otherwise, not so much. There's a really noticeable step up from 4K in that area. On a large TV though , it's probably an improvement over 4K for sports where you need to track a small item moving fast.
