Frequently asked questions
Why are the caption lines so short?
Short lines are easier to read at a glance on a phone and keep pace with fast speech. Switch to Normal for longer lines in tutorials and interviews.
Where should captions sit on a Reel?
In the middle of the screen or a little below it. The bottom fifth is covered by the caption text and buttons of the app.
Is my video uploaded?
No. Your browser extracts the audio track as a small mono file, and only that audio is sent to our server for speech recognition. It is deleted right after processing and in all cases within 24 hours.
How accurate are the subtitles?
Clear speech with little background noise transcribes very well. Strong accents, overlapping speakers, music and noise reduce accuracy. Always read through the result in the editor before publishing.
What is Hinglish?
Hindi written in the Latin alphabet, as many people type it in chats, for example 'aap kaise ho'. Choose it when your audience reads Hindi in Roman script.
Is it free?
Yes, with a short daily limit of free minutes. Aback Video Pro raises the limits for longer videos. The page shows how many free minutes you have left today.
Do I need an account?
No. Free use needs no account. Pro is unlocked with a licence key after purchase, also without an account.
Can I burn the subtitles into the video?
Yes. After editing, choose to burn them in; the video is rendered on your device with FFmpeg, just like Burn Subtitles.
Which file formats can I export?
SRT for most players and editors, and VTT for web players. Both keep the exact timings.
