Switched from manual captioning to Spark. Turnaround time dropped from hours to minutes, and accuracy holds up even with background music.
Batch processing for our weekly interviews is a lifesaver. The translation quality for Spanish and Japanese is surprisingly good.
Local processing is key for us. Students’ recordings never leave the device, while we still get accurate transcripts.
We ship videos globally. The 100+ languages support helps us keep captions consistent across regions.
Exporting clean SRT/VTT for multiple edits is smooth, and embedding subtitles directly into the video saved us a lot of delivery time.
