Troubleshooting common issues in Cubix

Keep the original media on your own drive. Record the project URL or identifier, browser and operating system, the action you were taking and the exact error message. Leave the project open while you check its status. Project saves can include timeline edits and captions, but an interrupted upload, offline edit or active request may not be recoverable after a reload. Do not clear site data or assume a refresh will restore every change.

Play the original clip outside the editor. If the same problem is visible there, investigate the source before changing the project. Note the container, video and audio codecs, duration, dimensions and frame rate. A file extension alone does not establish whether every stream can be decoded.

Keep the original file and record the upload status and error text. Check network availability, the file size and the current storage allowance in your account. If there is evidence of interference from an extension or network policy, an optional comparison in another supported browser profile can help isolate it. Avoid clearing storage, signing out or changing security settings as a first recovery step.

Record the requested operation, its start time and any visible progress or error. A slow response alone does not prove a server failure or lost work. Read any credit, storage or plan-limit message before deciding the cause. Keep the active project open and avoid submitting the same request repeatedly while its state is unclear.

Note where playback stutters or loses sync, and compare that point in the original clip. Reduce competing browser work where practical. If export is available, review a short downloaded result in another player. A preview problem and an encoded-file problem need separate investigation; neither result guarantees the other.

Record the export settings, current plan allowance, error text and failure time. Keep source files and project details while checking the issue. If a file downloads, open it outside the editor and review the affected point for picture, audio, captions and completeness. Current export Help and plan details are linked below.

Open Text → Subtitles → Review every subtitle and correct the affected text directly. The cue time fields use HH:MM:SS in whole seconds. Review nearby cues after an adjustment; do not enter raw milliseconds or SRT fractional timestamps into those fields. Before regenerating or importing another SRT, retain the original and your reviewed wording because replacement can overwrite captions for the chosen target.

Record which operation produced the unexpected result before making another change. If the operation offers Revert, Undo or an intensity adjustment, inspect its scope and review the result. Do not assume one undo restores every earlier state. For screen recordings, identify the quiet visual step that needs preserving when describing a follow-up request.
