Why can I add/remove a max of 100 characters at once?

If you're here, it's probably because you received this error message when trying to add or remove a large chunk of text from your transcript:

Here’s some context for why this happens:

Descript's text-editing functionality is there to help you fix transcription errors — so you should hopefully only be editing one or two words at a time. Once you make your fixes, Descript will quickly re-scan the region to sync your corrected text to its corresponding audio. 

Sometimes people try to add or delete large blocks of text. This can really confuse Descript’s algorithms, because the changes you're making don’t alter the audio portion of your document. Descript is trying to match your unmodified audio with your modified text, and the pieces don’t line up.
