LTX-Video states a length and no frame size

The repository states support for up to 60 seconds of video and no output size anywhere. It is the longest length claim in the register and the least specified frame, which is an unusual combination. As of 2026-09-12.

Inclusion rule. The value this page is about, the detail the vendor attached to it, and the two columns that change how it should be read. A column the vendor left empty keeps its row and says so. Order. This column first, then its detail, then the two columns that qualify it.

1The two missing columns compound

No frame size and no memory figure means the sixty second claim cannot be costed at all. Long output is where memory grows fastest, and neither of the values that would bound it is published.

The variant list, distilled and fp8 beside the full 13B, is the nearest thing to a hardware statement, and it says which direction the vendor cared about rather than how far.

2Why sixty seconds is the headline anyway

Most published video weights are documented around clips of a few seconds. A stated minute changes what the model is for, from a shot to a scene, and that is a bigger claim than a resolution.

It is the vendor's own figure in its own release notes and the register records it as that. Whether the output holds together across a minute is not a question a repository can answer.

3What a frame size would have added

Comparability. Every other length figure in the register can be placed against a resolution, so a reader can tell whether sixty seconds here means the same workload as ten seconds elsewhere.

Without it the claim stands alone. The register keeps the empty cell rather than reading a size off a sample clip.
