Cannot start upscale / 无法启动高档

[MidnightKittenCat]

Whenever I try to upscale I get this error:

Some fields are not entered correctly.
'FPS for upscaled video' field must be at least 4 characters.

So I go and check the video settings, set it to 24 fps and it won't let me change it.

Any help?

Translation:

每当我尝试升级时，我都会收到此错误：

某些字段输入不正确。
“用于放大视频的 FPS”字段必须至少包含 4 个字符。

所以我去检查视频设置，将其设置为 24 fps，但它不让我更改。

I figured out how to set the fps, but it still refuses to upscale:

When upscaling video, in addition to the video upscaling setting, the image upscaling setting must also be made for conversion.
Please make sure that the settings are done correctly.
