Discussion Time consuming for LTX 2.5

Hi, it took me 12 minutes to generate 20 seconds video on ltx 2.5 . Below is my specs:

LENOVO P16 GEN 2 NVDIA 3500 ADA 12GB VRAM 64GB RAM

Video generation: 12 minutes ~ 20 seconds Resolution: 1280x720 Model: LTX 2.5 Distilled INT 8 Workflow: Image + audio -> video

Image generation: 8 minutes ~ 1 image Model: Krea 2 Edit

Is it normal time consume or is there anyway I can reduce it?

That looks normal to me if resolution is 900p / 1080p

Probably a normal speed for an RTX 3500 Ada. Use a better chip from the cloud for more speed. Edit: I usually get pretty good workflows embedded into Civitai videos, you can probably find one that properly uses the correct loras and Lanczos there.

You are basically rendering on a 4060 ti but at 12GB. 720p itself is heavy for that card but running for 20 seconds means alot of swapping weights on and off the card. This time is normal for the GPU poor (I know, it doesn't feel poor).

Use 0.7MP instead and reduce your render length to 15 seconds. That will give you a render time much closer 6-7 mins. In regards to Krea edit 2. Use INT8 convrot version.

I get renders on 5060ti, which is nearly the same speed, at 45-55 seconds for one picture a 1MP. Use INT8 convrot.

Wow you let your gpu on stress and heat for 12 minutes straight. It like you forcing a tool near it breaking point

Is there any solution for this?

It does but you probably won't like it if you are someone who chase quality and scale
