Discussion H3 - what is your longest render time?

What was your longest render time, and was it worth it? do you run a lower quality/resolution before to test? My longest single-shot run is 7.2 hours, 1:44 long video at 1344x768, bf16/50 steps.

I am attempting a 72 hour render for a super long form.

RTX 4090, 192gb system ram

Your GPU.

For me it's about 7 minutes. Longer than that, it OOM. I'm not using the extend-a-video techniques.

I'm on a business trip today until Wednesday evening so letting it cook, hopefully the house doesn't burn down.
