Manual captioning drains hours
A two‑hour tutorial can take a full day to caption by hand. You type each line, sync it, and hope the timing stays right after a change. The effort adds up fast.
Sycamore does the heavy lift. It transcribes the whole video with word‑level timing, so you see every spoken word on the timeline. You only click the words that are wrong and type the correction. The rest stays synced automatically.
Common captioning pitfalls for long videos
Leaving the whole transcript unchecked and publishing errors.
Scan the transcript quickly, click any mis‑heard word, and correct it before export.
Using a tiny font that disappears on larger screens.
Pick a readable size in the style settings and test on both desktop and mobile.
Placing captions at the bottom where they clash with on‑screen graphics.
Put captions at the top or center so the video content remains visible.

Frequently
Asked Questions
How does Sycamore handle an hour‑long tutorial?
Upload the video, let Sycamore transcribe it, then fix only the words that are wrong. The timing stays, so you avoid re‑syncing large sections.
What video lengths can I caption on the Free plan?
The Free plan gives you 10 minutes of video on sign‑up. Paid plans count minutes of video you process each month.
Can I change the caption position after export?
Captions are baked into the MP4 at export, so you need to re‑export with a different position if you want to move them.
Do I need to export a separate subtitle file?
No. Sycamore burns the animated captions into the MP4, so the video plays with captions everywhere.
Is the transcription only for English speech?
Yes. Sycamore currently supports English only.
