BIN: glTF Buffer Companion

Binary buffer companion for the textured mini glTF (positions, UVs, indices).

BIN: glTF External Buffer Payload

The binary payload the external-buffer glTF in this group points at: tightly-packed positions, normals and indices with 4-byte alignment padding. Not viewable on its own: its bufferViews live in the JSON.

Binary versus Decimal Arithmetic: Where Floats Disagree (.csv)

Eight arithmetic expressions where binary floating point and exact decimal disagree, with both answers and the signed error side by side. Adding one cent a hundred times does not give one, and this file says by exactly how much.

Bitstream: All-Intra (Every Frame a Keyframe)

Every frame is an I-frame, so any frame is an independent cut point. Much larger, and the shape editing and frame-accurate seeking want. Same picture and same codec as every other clip in this group; only the GOP and frame-type structure differ, so the effect on size and seekability is directly attributable.

Bitstream: Heavy B-Frames (8 Consecutive)

Eight consecutive B-frames with a B-pyramid, so decode order and display order diverge sharply and DTS runs well behind PTS. The case that breaks naive timestamp handling and any code that assumes frames arrive in display order. Same picture and same codec as every other clip in this group; only the GOP and frame-type structure differ, so the effect on size and seekability is directly attributable.

Bitstream: Long GOP (24 Frames, One Per Second)

One keyframe per second: the delivery default, and the setting that determines HLS/DASH segment boundaries, since a segment must start on a keyframe. Same picture and same codec as every other clip in this group; only the GOP and frame-type structure differ, so the effect on size and seekability is directly attributable.

Bitstream: No B-Frames

I and P frames only. Required by some low-latency and legacy decoders, and it removes the reordering that makes decode order differ from display order. Same picture and same codec as every other clip in this group; only the GOP and frame-type structure differ, so the effect on size and seekability is directly attributable.

Bitstream: Short GOP (8 Frames)

A keyframe every 8 frames with scene-cut detection disabled, so the GOP length is exactly what it says. Short GOPs cost bitrate but bound seek latency: the trade-off streaming packagers make explicitly. Same picture and same codec as every other clip in this group; only the GOP and frame-type structure differ, so the effect on size and seekability is directly attributable.

Bitstream: Single GOP (One Keyframe Only)

Exactly one keyframe, at the start. Maximally efficient and nearly unseekable: a player must decode from frame zero to reach any position, which is what makes long-GOP archives painful to scrub. Same picture and same codec as every other clip in this group; only the GOP and frame-type structure differ, so the effect on size and seekability is directly attributable.

Branching Disclosure Form (HTML)

A single page whose visible questions depend on the request type chosen. Three mutually exclusive blocks are present in the markup at all times, so the same file exercises both an automation that reads the DOM and one that only sees what is on screen.
