❓ Frequently Asked Questions (FAQ)

• Q: What formats are supported?

  A: Imports support common audio and video formats like MP4, MOV, and MP3, as well as SRT and ASS subtitle files; exports support MP4 video, SRT, ASS, and XML (for use in PR/FCP).

• Q: How accurate is the recognition?

  A: Officially claimed to be over 95%, but actual accuracy depends on recording quality, background noise, and accents. Generally, some manual proofreading is still required.

• Q: What if speech recognition fails?

  A: First check your network (recognition requires internet access); if the network is working, the audio format might not be supported or the file could be corrupted. Try changing the format. If the issue persists, contact customer support.

• Q: The exported video has black bars/blurry subtitles?

  A: Adjust the encoding parameters (such as CRF mode) in the export settings; if there are black bars when importing into other software, it might be a subtitle transparency issue. Adjust the blend mode in the corresponding software.

• Q: Are there any keyboard shortcuts?

  A: Yes. For example, the J key sets the start time, K sets the end time, and Ctrl/Cmd+Z undoes. Once you're familiar with them, efficiency improves significantly.
