Frequently Asked Questions

A: Upload your MP4, select the spoken language and recognition mode, then choose Generate SRT. Review the timestamped captions and download the finished .srt file.
Q: Can I convert MP3 audio to SRT?
A: Yes. Upload an MP3 recording and the same speech recognition workflow will create timestamped subtitles and a reusable transcript.
Q: Which video and audio formats are supported?
A: The tool supports common video and audio files including MP4, MOV, AVI, MKV, MP3, AAC, WAV, FLAC and M4A. SRT is the primary subtitle output.
Q: How accurate is AI subtitle generation?
A: Accuracy depends on recording quality, background noise, accents and speaker overlap. Clear audio and the correct source language produce the best result; always review names and technical terms before publishing.
Q: Does the subtitle generator support Vietnamese?
A: Yes. Vietnamese is supported alongside English, Japanese, Chinese, Korean, Spanish, French, German, Thai, Arabic and more than 100 languages in total.
Q: Can I upload a MOV, AVI or MKV video?
A: Yes. You can upload MOV, AVI and MKV files as well as MP4. Processing time can vary with file size, duration and the media codec used in the source file.
Q: Can I export subtitles as VTT?
A: Yes. After transcription, use the download format selector to export WebVTT (.vtt). You can also download SRT or a plain-text transcript.
Q: Can I edit subtitles before downloading them?
A: Yes. You can review generated caption blocks, keep the original timing, split by a maximum word count, or use sentence-based formatting before export.
Q: Can I translate the subtitles afterward?
A: Yes. Download the SRT and continue with Subtitle Translator to translate caption text while keeping the subtitle workflow organized.
Q: Can I generate an AI voice from the subtitles?
A: Yes. Open SRT to Speech after generation to map subtitle timestamps to AI speech and create a synchronized voiceover.
Q: Can I process long videos?
A: Long videos can be processed, although upload and transcription take longer and usage depends on your account limits. For the best experience, use a stable connection and a clean source recording.
Q: How secure are uploaded video and audio files?
A: Files are uploaded through the application's secure storage workflow and are not used to train models. Avoid uploading content you do not have permission to process.
Q: Does Video to SRT add subtitles to the video itself?
A: No. This tool creates a separate subtitle file. Import the SRT into YouTube, TikTok, a video editor, or continue to Video Localization when you need a translated final video.
Q: What is the difference between an SRT file and a transcript?
A: An SRT file contains numbered caption blocks with start and end timestamps. A transcript contains the spoken text but may not include subtitle timing.
Q: Why should I create subtitles for a video?
A: Subtitles improve accessibility, help viewers follow videos without sound, support localization, and provide text that can be reused for search, editing and content repurposing.
