A floor against a set of smaller builds
FramePack states 6GB for 1800 frames and names the supported card generations. LTX-Video states no minimum and publishes distilled and fp8 builds beside its 13B model. Both are answers to the same question, in different currencies. As of 2026-09-22.
| Point | FramePack | LTX-Video |
|---|---|---|
| Hardware, as each vendor states it | 6GB minimum for 1800 frames at 30fps | No minimum stated |
| The detail published beside it | RTX 30XX, 40XX, 50XX with fp16 and bf16 | Smaller variants published for lower memory instead |
| Resolution, from the same pages | No output size recorded | No output size recorded |
| Length, from the same pages | 1 minute, 1800 frames at 30fps | Up to 60 seconds on the 13B |
Inclusion rule. Two families whose published values in this column lead to opposite decisions. A pair that happens to agree is not listed, because agreement is already visible on the column summary. Order. The column itself first, then its detail, then the columns that qualify it.
1Variants are a real answer and not a value
Shipping an fp8 build is a decision that costs engineering time, and nobody spends it unless memory is binding for part of the audience. As evidence it is strong.
As a register entry it is unusable. There is no column for a download list, and the hardware cell for LTX-Video is therefore empty while the page is not silent.
2What the stated floor gives up
Precision invites correction. A 6GB claim can be tested by anyone with a 6GB card, and a release that publishes it accepts that risk.
It is also narrower than it looks: the figure is for 1800 frames at 30fps on the 13B model, and no frame size is stated, so the claim covers one described output and not the release in general.
3The length claims pull in opposite directions
FramePack ties its floor to a minute of output. LTX-Video states up to sixty seconds and attaches no memory figure to it at all.
So both releases talk about long output, and only one of them says what long output costs. That is the practical difference between the two rows.
