    Wan2.1:

    It is recommended to use with lightx2v Wan2.2 v1.1 lora.

    This lora depicts the character Shiina Yuika(椎名唯華) from Nijisanji

    Trigger Word:shiina yuika nijisanji, anime style girl. An anime-style character with pink hair and a casual school outfit, featuring a beige cardigan, red bow tie, and plaid skirt

    Trained: musubi-tuner, 20 images

    Caption: adjusted short caption from ChatGPT (includes described background)

    sample prompt:shiina yuika nijisanji, anime style girl. An anime-style character with pink hair and a casual school outfit, featuring a beige cardigan, red bow tie, and plaid skirt, (she is dancing:1.8), (chibi Nendoroid:2.5) in bedroom.

    アクションは強調promptによって2.0~4.0に調整する必要があります。またはモーションloraを併用ください。

    Action prompt should be adjusted to 2.0 to 4.0 depending on emphasis prompt. Or motion lora use together.

    以下備考:

    ・キャラクター再現度とpromptの動きやすさはトレードオフで、おそらく生成プロンプト(トリガーワード)が長いほど再限度は上がるが、動きやすさは制限される。

    動きにくい場合はlora強度を下げるか強調promptが有効だがKijaiのワークフロー(https://civarchive.com/models/1335809/wan21-14b-chihaya-anon-mygo のワークフロー使用)だとprompt強調や{A|B|C}構文が上手く働かなかったのでTextEmbed Bridgeを使用するよう改造した。

    とはいえ今回のキャプションは短い目なので強調promptを未使用でも比較的動きは反映されやすいです。

    ・musubi-tunerの学習でHunyuanVideoよりblocks_to_swapを大きくしないとVRAM不足に陥りやすそうだった。

    しかし、Wan2.1のlora学習速度はHunyuanVideoと同程度だった。HunyuanVideoは14くらいで十分だったが、Wan2.1は24くらいにする必要があった。

    4070Ti(VRAM 12G) musubi tuner

    --blocks_to_swap 14 …198.27s/it

    --blocks_to_swap 24 … 3.3s/it

    ・推移損失:

    avr_lossは開始時0.100

    100epoch(2000step)で0.085

    230epoch(4600step)で0.065

    250epoch(5000step)で0.060

    ・文字が書けるか

    漢字は書けるようだ。ひらがな、カタカナは書けなかった。代わりに変な記号がでる。

    あと漢字を書くと何故か画質が落ちました。

    ・生成時間はHunyuanVideoの2~3倍かかるのでLoRAがあるならHunyuanVideoのほうが生成ガチャ出来る分有利かも…。

    HunyuanVideoで上手くいかなかったpromptをWanが描けるのかはまだ試せてないです。
