SubStamp –Transcribe&Translate

This app turns any video into a shareable version with clean, readable subtitles permanently burned in. Select a video, choose the spoken audio language, and generate timed captions. Optionally add a second subtitle language to create bilingual subtitles, then export a new video that plays with subtitles everywhere—no special player required. What you can do • Speech-to-text transcription with timestamps. • Translate subtitles to a second language when supported on your device. • Burn one or two subtitle tracks directly into the video and export a new file. • Preview, edit, and fix captions before exporting. Choose your translation mode • Standard Translation: Faster results. Good for quick drafts. • AI Translation: Slower but usually more accurate and more natural. Switch modes anytime depending on whether you want speed or quality. Designed for a smooth, guided workflow 1. Choose the audio language for transcription. 2. Subtitle 1 (required) is the transcript in the audio language and is always enabled. 3. Subtitle 2 (optional) is a translated track. The app only shows translation options available for the selected audio language, and can fall back to translating via English when a direct pair isn’t available. 4. Generate subtitles, review them, and export. Caption editing and readability • Edit text, timing, and line breaks so subtitles match your video. • Search within captions and jump to a time range to make fixes. • Adjust subtitle position, font size, and safe-area margins. • Improve contrast with background box, shadow, or outline options. • Bilingual layout options to keep two languages easy to read. Export options • Preserve the original audio. • Choose export quality and resolution where available. • Save the finished video to Photos or share it to other apps. Clear progress and reliability Long jobs can take time depending on video length. The app shows progress for language readiness, transcription, translation (if enabled), rendering, and export. You may see reminders to keep the app active during export if your device requires it. Language support and availability Speech recognition and translation coverage varies by device and system support. Some languages or language pairs may require downloadable on-device assets. If something isn’t ready, the app will explain what’s missing and guide you to set it up before processing. Privacy Your videos stay on your device.
