60-second AI short film, narrated

The whole thing: script, keyframes, clips and a voiceover. Every stage a measured first-party number, nothing assumed.

The pipeline

Write the script and shot list, qwen3-32b
Generate 15 keyframes, stable-diffusion-xl
Render 15 clips (~4s each), ltx-video
Narrate 60 seconds of voiceover, kokoro-tts

Fastest card where every stage is a real measurement: NVIDIA H100 80GB HBM3, 2.6 min for the whole job.

Every GPU, slowest job to fastest

GPU	Total time	Compute	Energy	Basis
NVIDIA H100 80GB HBM3	2.6 min	2 min	17.46 Wh	all 4 stages measured
NVIDIA H200	4.1 min	2 min	18.04 Wh	all 4 stages measured
NVIDIA A100 40GB SXM4	4.2 min	3.9 min	6.4 Wh	anchored estimate (3/4 stages measured)
NVIDIA A100 80GB SXM4	4.9 min	4 min	23.62 Wh	all 4 stages measured
NVIDIA L40S	5.1 min	4.3 min	22.53 Wh	all 4 stages measured

Cards that can't run this pipeline

Every one of these fails on the same kind of wall, a stage that will not fit in VRAM.

How these numbers are built

Each stage time is the quantity of work divided by that card's measured throughput for that model, from our own bench. The pipeline is assumed to run batched, every image, then every clip, so each model loads once. Model load time is added where we recorded it; our text-generation runs don't carry a load measurement yet, so pipelines with a language-model stage are slightly optimistic. Nothing here is a single timed run of the whole pipeline, and we don't present it as one.
