Thanks again to yuj***@gmail.com for the helpful feedback. Improvement: Greatly improved English subtitle recognition accuracy. In our internal tests, about 92% of subtitle sentences are extracted correctly, with most remaining errors occurring at sentence boundaries.

Special thanks to the user yuj***@gmail.com for the patient feedback and repeated communication, which helped me finally identify the root cause of the issue. Fix: When scanning large video subtitles, the system entering sleep mode could lead to unpredictable results. This update adds a control mechanism to temporarily prevent the device from sleeping during the subtitle scanning and extraction process, ensuring the task completes reliably. If you encounter any issues while using the app, please feel free to use the in-app feedback feature and leave your email so I can follow up if needed.

Thanks to aaa***@yahoo.com.hk for the feedback! This version includes the following updates: • Set the exact area for subtitle extraction: define X and Y coordinates to scan only the selected region. • Choose the source on iOS: open videos from Photos or Files.

Thank you for the feedback from at****039@gmail.com, this update introduces Multi-Frame OCR Consensus. By aggregating OCR results across consecutive video frames and enforcing temporal consistency, the algorithm significantly reduces recognition errors caused by background changes, motion, and fade-in subtitles. Subtitle stability and accuracy have been improved for Chinese, English, and Vietnamese content.
