104: RuntimeWarning: invalid value encountered in cast return tensor_to_int(tensor, 8).astype(np.uint8)

after the update, I can't generate videos anymore, i only get black screen videos, is anyone having this issue?

This is the error I am getting.

104: RuntimeWarning: invalid value encountered in cast

Thank you

This is unlikely to be a problem with VHS. If you instead connect the image output to a Preview Image node or a SaveAnimatedWEBP node, you will probably get the same black output.

This issue is not uncommon, but can be difficult to debug since no error is produced until the end. Try

• Pulling out parts of the workflow to find if there's a single node causing the issue
• Consider setting --preview-method latent2rgb as a launch flag. Are the previews in KSampler nodes ever not black?
