You can translate subtitles by pressing the translation icon button at the bottom right of the Subtitle Editing tab. After that, you can apply the sequence and add subtitles in two ways.
1. When creating a Premiere Pro caption track
You can generate the translated subtitles as a single caption. However, since Premiere Pro can only activate one caption track, please select the track and upgrade the caption to graphics from the [Graphics and Titles] menu.
2. When creating motion subtitles in Cutback
In the [General] menu of the motion subtitle editing menu, you can choose whether to include translated subtitles. You can also adjust the font, size, etc., of the translated subtitles in the [Style] menu.
