    This WF runs fast and works well. Questions tho, this is a ref2va WF but it uses fl2va diffusion models? Or it can use both model types? Sorry, new to minimax.

    i think both you can try it, i have not tried video editing reference but multi reference image to video its working well

    @RedditUser9811 Thanks. Yes, both seem to work but give different output.

    Yes, you can change te model to REF, but that model its taking like 6x time to create a video in REFV2V mode D:

    Runs perfectly and incredibly fast. 2x faster? than the base h3 i2v template. ALL the speedups are meaningful. Setup was incredibly easy. 10+ second videos are easily within reach without ridiculous gen time using this workflow. Running on an RTX 4070ti Super, in Pop!_OS 24.04 LTS.

    Just tested it. Surprisingly fast on a 3060 and 32GB of RAM (DDR4). 5 seconds and 0.3MP - 223 seconds. 6 seconds and 0.4MP - 337 seconds.

    I have a question. Why so many references? Can I add multiple different photos? Or how does it work?

    First of all, a huge thank you for the truly awesome workflow. Even though I installed SageAttention according to the guide, it still crashed the process. Even with it disabled, the video generation speed at 0.2 took 327.45 seconds (24 fps / 8 seconds). This is amazing!

    Please tell me, will there be a workflow version for ITV?
