How long a clip each family states
LTX-Video states support for up to 60 seconds. CogVideoX1.5-5B states up to 161 frames at 1360x768, which the repository describes as 5 or 10 seconds. Mochi 1 states 480p as its current capability without a length. As of 2026-09-12.

Inclusion rule. Lengths stated in the vendor's own repository. A length reached by chaining generations is a different claim and is not recorded. Order. By the longest stated figure.
1Frames and seconds are not interchangeable and the repositories know it
A frame count is exact; the seconds it becomes depend on the frame rate. The family that publishes frames also supplies the translation, which is the careful way to do it, and this register carries both rather than picking one.
Any table that converted everything to seconds would be doing arithmetic the vendors deliberately did not do.
2A supported length is not a usable length
Support for a duration means the code path runs to the end. Whether the result holds together over that duration is a separate question that nobody publishes an answer to, in either direction.
Treating the longest figure in this table as the best is therefore a mistake the table invites and the rule line tries to head off.
3Silence about length is common and worth recording
One family states a resolution as its present capability and no length at all. That is recorded as not stated rather than as unlimited or as short, because a repository that has not addressed it has not committed to anything.
Against the hosted services in this register, which mostly sell tens of seconds per generation, the open figures are in the same range with one exception.
