Students need readable captions
A lesson video often contains technical terms that viewers must see to remember. When captions run too fast or crowd the screen, the learning breaks. Sycamore gives you word‑level timing so each term appears exactly when you say it.
You can set words per line, choose all caps or a bold outline, and pick a highlight color that contrasts with your slides. The result is a caption that reads smoothly without distracting from the content.
Common caption mistakes in lessons
Running a full paragraph across the bottom of the screen.
Limit captions to 2‑3 words per line and place them at the top so they don’t cover diagrams.
Using a font color that blends with slide backgrounds.
Pick a high‑contrast text and highlight color that stands out on any slide.
Leaving technical terms mis‑heard by the transcription.
Click any word in the transcript and type the correct term; timing does not change.

Frequently
Asked Questions
How do I add captions to an educational video?
Upload the lecture to Sycmore, pick a caption template, correct any misheard terms, and export the video with animated captions burned in.
Can I control how many words appear per line?
Yes. You can set the words per line in the editor to match the reading speed you want for your students.
What if the transcription gets a scientific term wrong?
Click the word in the transcript, type the correct term, and the timing stays where it was.
Does Sycamore work with slide decks that are 16:9 or 1:1?
Yes. Captions work on 9:16, 16:9 and 1:1 videos, so you can keep your original aspect ratio.
Are the captions exported as a separate file?
No. Captions are burned into the MP4 so they appear on every platform without extra files.
