How do you handle mathematical notation?

Our goal is make the text as readable as possible. Sometimes it makes sense to spell out numbers. We usually spell out numbers from zero to ten. However, we try to group signs and numerals together. Examples:

  • 2x + 15y = z
  • 2 x 3 = 6
  • R equals delta T
  • 15^6 (15 to the 6th power)

If you have preferences for how to notate math or other complex text, please let us know and we’ll try to accommodate your requests.

What is the review and quality control process?

Each caption or transcript we create in house gets a full, human, review. We also run an assisted spell check. If you find errors, we will promptly correct

What is the difference between open and closed captions?

Open captions are burned into the video. They cannot be turned off. Closed captions are embedded in the video and can be turned on or off.
