SVD Model can be found here, this is specifically for ComfyUI - Kijai/AnimateLCM-SVD-Comfy at main (huggingface.co)

\Workflow to make better videos closer to Luma quality. Use an Int image or use text, will need to change some connections. Color match to fix SVD output a bit, cascade for a decent image with prompts embedded, SVD for an int video for animateDIff as it always seems to work better with an int video lol. And then AnimateDiff to make it a bit smoother and better.

Play with the settings, find what works for your style and project. It takes a lot of tweaking to find the settings you need.
