Got this running on a GTX 1650 (4 GB VRAM, laptop GPU) --- turns out you don’t need much VRAM to get solid results!

Model: ltx-video-2b-v0.9.5.safetensors
VRAM usage: ~2.7–3.5 GB
Render time: ~3-9 minutes in total
Resolution: Test at 768×512 (took ~27 minutes total). The sample videos below are 640×480. (except the last one)
Steps: 30
Frames: 73
FPS: 24

Environment: i5-12450H, 20 GB RAM, Windows 11, SSD

I mostly left the settings at default, just adjusted frame count, resolution, and FPS.
Really impressed with this --- 9.5/10, highly recommend.

I do have a question; will the spatial and temporal upscalers work with the 2b 0.9.5 model?

Hi, yes, they will!

Hi, yes, they will!

I have tried using the upscalers with both the dev and distilled fp8 2b model, yet there appears to be no visual differences. I have also gotten outputs in the terminal stating that the LoRA keys have not been loaded, so I will try with the 13b model.
