アクションは強調promptによって3.0~5.0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。

lightx2v Wan2.2 v1.1との併用を推奨します。

Action prompt should be adjusted to 3.0 to 5.0 depending on emphasis prompt. Or motion lora use together.

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

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://civitai.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。

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。
