Refer to gallery videos comments for examples and parameter recommendation from the linked article. Prompt tips (green - positive, red - negative): - Anime style - required to keep the style, you can make him fully realistic if you remove this tag or use Realistic instead - For correct Japanese dialogue use He says in Japanese " " and put text as romaji in the quotes - Shot types: Close-up shot, Medium close-up shot, Medium wide shot, Wide shot - He is wearing a grey cap, a white and green striped polo shirt over a blue undershirt - alternative clothesI2V support:- The Lora works with I2V, however, do not expect amazing results. It was not trained with I2V focus and LTX2 right now does not perform great with flat 2D styles either.Most of the I2V source images can be found on my Seiichi Kinoshita Illustrious page. Known issues:<ul><li>The Lora is currently biased towards close-up/medium shots by default. Solution: provide more details about what the character is wearing (e.g. trousers, shoes) to force wider shots or change resolution to square/portrait</li><li>Will occasionally generate in realistic style. Solution: either change seed or add "Anime style animation" or "Animated in Anime style" in the prompt</li><li>In weird/unusual angles will sometimes lose character consistency and become skinny Solution: add fat/obese to describe him</li></ul>Training info:<ul><li>Trained on 82 videos and 8 images using the Musubi LTX2 fork: <a target="_blank" rel="ugc" href="https://github.com/AkaneTendo25/musubi-tuner">https://github.com/AkaneTendo25/musubi-tuner</a></li><li>Training buckets used - images: 960x512 / 864x864 / 1152x640 || videos: 736x416 / 800x448</li><li>Frame length: between 25 and 121 frame videos</li><li>Training time: 7000 steps total, Lora taken from 5300 epoch</li><li>Training parameters below extracted from Lora metadata:</li></ul><pre><code>"ss_logit_mean": "0.0",

Seiichi Kinoshita - LTX2 (SHIROBAKO)

My first attempt at a LTX2 character LoRA. Trained on Musubi Tuner LTX2 Fork. Big Thanks to AkaneTendo25 for the amazing fork. This is a beta release. I already have ideas for further improvements but I am quite happy with results so far.The Lora can do I2V but it was trained with default I2V support (ltx2_first_frame_conditioning_p 0.1) which means I2V isn't great. But this is also because LTX2 in general isn't currently work great with 2D flat animation. Source I2V images come from my Seiichi Illustrious LoRA (on my profile).
