I edit videos on a hobbyist level (mostly using davinci resolve to edit clips of me dying in video games to upload to a shareX host to show to friends). The big takeaway for me was reading that for quality/efficiency libx264 is better than nvenc for rendering h264 video. All this time I’ve assumed nvenc is better because it used shiny GPU technology! Is libx264 better for recording high quality videos too? I know it will run on CPU unlike NVENC but I doubt that’s an issue for my use case.

Edit: from some googling it looks like encoding is encoding, whether it’s used for recording or rendering footage. In that case the same quality arguments the article is making should apply for recording too. I only did a cursory search though and have not had a chance to test so if anyone knows better feel free to respond

You might want to try dumping your work from Resolve out in ProRes 422 HQ or DNxHR HQ and then encoding to h264/h265 with Compressor (costs $; it's the encoder part of Final Cut as a separate piece of software) on a Mac or Shutter Encoder. Also, I'm making a big assumption that you're using the paid version of Resolve; disregard otherwise. It might not be worth it if your input material is video game capture but if you have something like a camera that records h264 4:2:2 10bit in a log gamma then it can help preserve some quality.

It’s impossible to keep my 5800x below 90C under full load.

The Ryzen CPUs seem to be designed to spike as high as whatever thermal limit you configure with Precision Boost Overdrive.

As someone else who was homeschooled except the last three grades, I also agree. Additionally, the effect is multiplied if the kid in question lives in a rural or semi-rural area rather than a suburb or city.

For the majority of my adult life I’ve been playing catchup. Even now, barreling towards 40, there’s aspects of social capabilities where I come up quite short relative to my peers.

If I’m ever to be a parent, I won’t homeschool. Depending the circumstances I might not send my kids to public school, but their schooling situation will at minimum involve social exposure comparable to that of public school.

I identify with your post as a rural kid who mostly didn't socialize with classmates after school. I went to public school, and I'm 40 now. I think the human experience is that you are inevitably going to encounter social situations where you feel outmatched or simply don't belong. I do agree with making sure your kids experience public school, but I think that's about the bare minimum of what you can offer your kids.

> high megapixel sensors, pre-capture, and cameras capable of pushing between 30fps and 120fps worth of compressed raws or high quality JPEGs

Surely those are buffered in the RAM first, then flushed to the card. When the buffer is full, cameras either stop recording or have to flush continuously, which reduces the burst rate.

zten · 4 months ago
Yes, that's correct. Buffer sizes are also all over the place, so if you want to shoot continuously, you need to pick carefully. Check https://www.fredmiranda.com/forum/topic/1856860/0 for a thorough analysis starting with the Sony A9iii (which can fill the buffer incredibly quickly with its premier feature, the 120fps 14-bit raw output global shutter). Deeper in the thread compares to the Nikon Z9.

My advice is to have "some fair number" of SD cards and when you are done with the card in the camera, put it aside and install another card that hasn't been used in awhile.

Because managing files is not only error prone, deleting files should be avoided to the extent your budget allows...

...and if you are shooting still (and not video) there's really no good reason to ever delete an image off an SD card because SD cards are cheap (because photos don't require highest speed cards). SD cards can be used as "film" in a digital camera.

> because photos don't require highest speed cards

That hypothesis is certainly getting tested these days in specific niches. With high megapixel sensors, pre-capture, and cameras capable of pushing between 30fps and 120fps worth of compressed raws or high quality JPEGs, you can obliterate your camera's write buffer and CFExpress write bandwidth. You can make many bad photos of an animal, bird, or athlete with extreme ease -- and hopefully find that one winner in the haystack.

I would say the line between movies and photos is getting blurred, but it's unlikely you're using a shutter speed that allows for motion blur with these bursts of photos!

I realized if someone were to assign me the ticket for fixing this behavior, I would have no idea where to begin with solving it even with this blog post explaining the problem, so I'm very curious to know what the most practical solution is. (They obviously aren't adding "If someone asks you about a seahorse emoji, there isn't one available yet, no matter how strongly you believe one exists." to the system prompt.)

I started buying Blu-ray discs and ripping them to my computer, where I run Plex. Why? I had a long-time subscription to HBO Max, but a few years ago, I went to watch Westworld, and it was gone from HBO. I ended up buying a season on Apple for the price of a monthly subscription to HBO. I cancelled my HBO subscription. I realized that second-hand Blu-ray discs of shows were selling for dirt cheap. I spent $40 to buy the rest of the seasons of Westworld on Blu-ray.

Clearly, new shows aren't getting Blu-ray releases, so this won't work for you if you care about new shows. My wife and I are so over the dystopian view from modern science fiction that we started focusing on shows from the late 1900s (80s/90s) to get more of a positive outlook from our entertainment. We are now going through Stargate SG-1.

Sucks that the Blu-ray experience is dreadful for 4K content. You've gotta find specific Blu-ray drives with specific firmware versions to do rips, or watch on a PlayStation or similar locked-down console. There isn't even a non-pirate way to watch on a laptop or desktop anymore since Intel SGX is dead.

The vast majority of people run just one gpu, which motherboards have a dedicated direct to CPU x16 slot for. Stealing lanes comes into play with chipset connected slots
zten · a year ago
I bought a Gigabyte X870E board with 3 PCIe slots (PCIe5 16x, PCIe4 4x, PCIe3 4x) and 4 M.2 slots (3x PCIe5, 1x PCIe 4). Three of the M.2 slots are connected to the CPU, and one is connected to the chipset. Using the 2nd and 3rd M.2 CPU-connected slots causes the board to bifurcate the lanes assigned to the GPU's PCIe slot, so you get 8x GPU, 4x M.2, 4x M.2.

I wish you didn't have to buy Xeon or Threadripper to get considerably more PCIe lanes, but for most people I suspect this split is acceptable. The penalty for gaming going from 16x to 8x is pretty small.

The B&H example is ridiculous and I definitely would churn if I ran into that.

However, we can just put business hours on support, and would expect that the websites would generally work, unmonitored, while the SREs maintained a normal 40.
