SubLunioFix missing, incorrect or out-of-sync subtitles
First identify the stage that failed: reading the file, choosing audio, generating text or displaying the download. Check one concrete symptom at a time. SubLunio supports 110+ target subtitle languages, with a preview to help you inspect results before continuing.

The file cannot be inspected or extracted
Confirm that the file is fully downloaded and opens in a trusted local media player. A recognizable extension does not guarantee that the file is complete or that its internal codec is supported. A partially copied recording can contain a readable opening but fail later. Keep the original in place while local processing runs, and ensure the device has enough available storage for the extracted audio.
If the browser reports a missing local media engine or an unsupported decoder, retrying a paid action is not the solution. Check the displayed error and use a supported file or the desktop workflow where available. Protected media is not decrypted by SubLunio. A source that needs repair should be repaired with an appropriate media tool before you rely on its duration and timeline.
The preview is empty or contains the wrong speech
Listen to the selected audio track. An empty channel, commentary track or music-only introduction can explain an unhelpful result. The preview starts from the first detected subtitle rather than automatically consuming 5 minutes of opening silence, but speech still has to be present and intelligible. Quiet dialogue, overlapping speakers or a badly damaged recording can reduce recognition quality.
Check the source language if the text resembles the wrong language, and confirm that your target selection is the language you intended to read. The 110+ target languages describe translated subtitle output; they do not imply that every possible source language or dialect is recognized equally. A glossary can guide names and terminology, but it cannot supply missing dialogue or guarantee that every line is correct.
The subtitle exists but the player does not display it
Load the downloaded file explicitly from your player’s subtitle menu. If that works, organize it beside the video with a matching base name for easier automatic discovery. Show file extensions in your file manager and check that the download has not acquired an extra .txt ending. Make sure you opened a subtitle, not an HTML error page saved under a subtitle-looking name.
Check which track is active. A player may still be displaying a subtitle embedded in the video or a previously loaded external file. Choose a line you can recognize and compare it with the downloaded text. If the application does not support your selected format, download an appropriate SRT, VTT or ASS version rather than merely changing the extension.
Every line has the same timing offset
A constant offset means the subtitle is consistently early or late. First confirm that it belongs to the exact video edition. An extra logo or trimmed introduction can shift every line by the same amount. Some players provide a subtitle delay control, which is useful for a local viewing adjustment. Note the amount and direction before applying it so you can undo the change.
Check more than the opening scene. If the same adjustment works near the end, the issue is plausibly a fixed offset. If it does not, stop increasing the delay repeatedly and investigate a different edition or duration mismatch. Player-specific delay settings may persist between videos, so reset them before evaluating a newly generated subtitle.
Timing drifts, characters break or bilingual lines overlap
Growing drift often needs a different diagnosis from a fixed offset. Compare the duration and edit points of the source and the video being played. A subtitle generated for one cut may cross removed scenes incorrectly. Reusing the subtitle on another version without retiming is not a reliable shortcut. Generate from the actual file when that is the simplest way to preserve the correct timeline.
For broken characters, check the player’s encoding and font settings. Use UTF-8 and a font covering the script; try the download BOM option only when the receiving application requires it. For cramped bilingual lines, reduce the font size or use a compatible styled ASS track. Rendering right-to-left text also depends on the player, so inspect the actual destination application.
An interrupted task needs recovery rather than another payment
Return to your account history or use the recovery information saved for the guest task. Signing in from the same browser can attach the existing task to your account. Keep the original local file available if the interface asks you to resume an upload or reconnect preview media. A request to select the file locally does not always mean that the server needs another full audio upload.
Read the task state and balance history before creating a replacement job. A failed generation and an interrupted browser connection are different events. If you contact support, provide the task identifier, approximate time and visible error. Do not send passwords, payment card data or the entire movie. Clear diagnostic details make it easier to identify a recoverable task without exposing unrelated content.
A few things worth knowing
Will downloading ASS fix incorrect words?
No. Format changes affect packaging and styling, not recognition or translation accuracy.
Should I pay again when the page closes?
First recover the existing task through the same browser or your account history and check its state.
Why are subtitles synchronized at the start but wrong later?
Check for a different video edition, cuts or duration mismatch. A constant player delay may not fix growing drift.
What should I include in a support request?
Use the task ID, approximate time, selected format and visible error. Avoid passwords, card details and unnecessary media attachments.
