レスポンシブテロップで境界線を付けたシェイプを使うと、文字数によって境界線の太さが変わってしまいます。太さを変えずに追従できるように改善してほしいです。

Dear @akari_1728,

I believe After Effects just announced features that can achieve this function with expressions, which I think you would need for such an effect. See this article: https://adobe.ly/4a8UCDu. Have you checked it out? Let us know if that new feature is what you are looking for. I hope the advice helps. If not, we hope to further help you. Just let us know.

Thanks,
Kevin
