Animatediff Latent Upscale (Instant crash on Mac)

[aianimation55]

Hey,

Quick question incase it's fixable and related to Animatediff rather than ComfyUI.

*I appreciate there are issues with utilsiing Macs and ComfyUI . (*I'm running a 128gb Mac M2Ultra).

I'm successfully generating videos with Animatediff via Comfy. At 640 x 360.

If I add a Latent Upscale, as seen in the AniamtedDiff examples. i.e. with one set up to upscale 1.5x . Comfy Crashes as soon as it hits the node.

Any ideas? (*Other than getting an. Nvidia Pc :-)

what error message?

Thanks, here's the Terminal output where it runs the standard genration, then crashes once it reaches the Ksampler after the Latent Upscale node.

Seems to be fixed when I include ' --use-split-cross-attention' when loading Comfy, (thought I'd tested this before, but seems to help now).
