Yes, you do not need to upload a video transcript / video script in order to receive captions. We always use proof-read AI-generated captions (subtitles).
Although if you do have a transcript or a video script, that would help your editor speed up the process, hence having a quicker turnaround time.
We will transcribe your video and all captions will also be double-checked by your editor to leave as little space for error as possible.
With a Scale plan and a Pro plan you get unlimited English.
