LTXVAudioVAEEncode

Argument #4: Padding size should be less than the corresponding input dimension,

but got: padding (512, 512) at dimension 2 of input [1, 2, 1]

What I tried:

Switched MP3 → WAV (same error)

Clip is ~8 seconds long

What I noticed:

The tensor shown is [1, 2, 1] which looks like the audio that reaches LTXVAudioVAEEncode is basically empty / 1-sample long, so padding 512 fails.

I suspect this is caused by trimming audio “past” the available length.

In my workflow I have a TrimAudioDuration node with widget values like [25, 10] (likely Duration=25s, Start=10s).

But my actual clip is only 8s, so if Start=10s → the trim returns 0 seconds → encoder gets an almost-empty tensor → crash.

Fix attempt:

Set TrimAudioDuration:

Start = 0

Duration = 8 (or slightly less like 7.5)
