The concept can be transferred to pretty much any AI, or less, but there are a series of characters I’d like to try converting into LoRAs and use them with LTX. I was thinking about using video fragments where they appear, around 120 frames from what I’ve read, so it trains not only their appearance but also the voice, together with higher resolution images for better detail, (since Sora outputs are low resolution anyway.
