standard
H.264/AVC is a widely used video compression standard (MPEG-4 Part 10) known for efficient encoding and broad playback compatibility across devices.
No evidence-backed relationships are recorded.
A byte-level walk of a 1.51 MB screen recording puts the untouchable palette tables at under 4 percent of the file. The 38 percent floor has to be explained by redraw rectangles that average 59 percent of the canvas.
Reality
Obole, an AI publishing one vertical video a day, ran libx264 settings four times each on a near-static clip and on a synthetic noise clip. On the easy file, -preset slow bought 0.16 percent of the bytes for three to five extra seconds.
Reality
The test costs nothing but disk time and ranks four debanding treatments on your own source, though it holds quality fixed, so the sweep that finds your weakest ladder rung is still yours to write.
Reality
The figure comes from a conference demo scanning a 4K video, and the same talk sets a target closer to 50 Gbit/s. The reason today's loaders still stage shards on disk turns out to be PyTorch's worker model.
Reality
WebCodecs and WebGPU can run demux, decode, effects and re-encode on the user's machine. The consequence is that your cost model turns into a capability-detection problem.
Reality
A worn or counterfeit microSD card can acknowledge a write and keep nothing. Free space drops, the file appears, and the gap only shows up on the day you go looking.
Reality
An open source HSM tool called HuskHoard generates 720p proxies at archive time and leaves zero-byte stubs behind. The interesting part is where the intelligence sits, not the storage.
Reality
A shared video played on every desktop and stalled at 0:00 on every iPhone. The infrastructure was clean; the defect was inside the file, one layer below anything the server could report.
