How to Review Subtitles Before Export

Export should be the final step of a subtitle project, not the moment when editing simply stops.

Before exporting subtitles from Sublandia Editor, you should review the file carefully and make sure it is ready for delivery, playback or further processing. A subtitle file can look finished because the text is entered, but still contain timing problems, reading speed issues, line length errors, gaps, overlaps, spelling mistakes or wrong export settings.

Sublandia Editor helps with real-time validation, but final review is still important. Automatic QC can show technical warnings and errors, while human review helps confirm that the subtitles are accurate, readable, natural and appropriate for the project.

This guide explains what to check before exporting your final subtitle file.

Why Final Review Matters

Final review is the last quality control step before export.

It helps you catch problems that may not be obvious while editing line by line. When you review the full subtitle file, you can check how the subtitles work as a complete viewing experience.

Final review helps you confirm:

• subtitles are synchronized with the video
• text is correct and readable
• timing feels natural
• QC errors are fixed
• warnings have been reviewed
• line breaks look clean
• spelling and terminology are consistent
• export format matches the delivery requirement
• project settings are correct
• the project is backed up if needed

A good subtitle workflow does not end with typing. It ends with review.

2. Review Subtitle Sync

Check whether the subtitles match the video from beginning to end.

Do not only review the first few lines. A subtitle file can start correctly and slowly drift out of sync later.

Check sync in several places:

• near the beginning
• around the middle
• near the end
• after scene changes
• after long pauses
• after imported or edited sections
• after any major timing correction

If all subtitles are shifted by the same amount, you may have an offset problem. If the problem becomes worse over time, check FPS, video version or subtitle template compatibility.

4. Fix Overlaps

Before export, make sure there are no unintended subtitle overlaps.

An overlap happens when one subtitle starts before the previous subtitle has ended. This can cause display problems, confusing reading or validation errors.

Check whether:

• one subtitle starts before the previous one ends
• two subtitle events are active at the same time
• overlap warnings or errors appear in QC
• fixing one subtitle created a new overlap nearby

Overlaps should normally be fixed before export.

6. Review CPS and Reading Speed

Sublandia Editor validates CPS automatically in real time.

CPS means characters per second. It tells you how fast the viewer needs to read a subtitle while it is on screen.

Before export, review all CPS warnings and errors.

In Sublandia Editor:

• Yellow means the CPS is above the optimal value but still within the maximum allowed value
• Red means the CPS exceeds the maximum allowed value defined by the selected ruleset

Check whether subtitles with high CPS can be improved by:

• shortening the text
• extending the duration
• splitting the subtitle
• rewriting the sentence
• improving timing

A subtitle can be textually correct and still be too fast to read.

7. Review CPL and Line Length

Sublandia Editor also validates CPL automatically.

CPL means characters per line. It checks whether a subtitle line is too long visually.

Before export, review CPL warnings and errors.

In Sublandia Editor:

• Yellow means the line is between the optimal CPL and maximum allowed CPL
• Red means the line exceeds the maximum allowed CPL defined by the selected ruleset

Check:

• line length
• line breaks
• one-line and two-line balance
• grammar and meaning
• whether closely connected words are separated
• whether the subtitle looks clean on screen

Line breaks should not be random. They should follow meaning, rhythm and natural language structure.

8. Check Minimum and Maximum Duration

Sublandia Editor validates subtitle duration in real time.

A subtitle can be marked with a red error if it is:

• below the minimum duration
• above the maximum duration

Both limits are defined by the selected ruleset.

Before export, check that subtitles are not too short or too long.

A subtitle that is too short may flash on screen and be difficult to read. A subtitle that is too long may remain visible after the speech has finished and feel unnatural.

9. Review WPM and Other QC Warnings

Sublandia Editor can also validate WPM, number of lines, gaps, overlaps and other ruleset-based checks.

WPM means words per minute. It measures reading speed based on word count instead of character count.

Before export, review all QC indicators:

• CPS
• CPL
• WPM
• number of lines
• too short duration
• too long duration
• gap too small before subtitle
• gap too small after subtitle
• overlap

Red errors should normally be fixed. Yellow warnings should be reviewed and either improved or intentionally accepted based on context.

10. Check Spelling, Grammar and Punctuation

Technical validation is not enough.

Before exporting, review the subtitle text for language quality.

Check:

• spelling
• grammar
• punctuation
• capitalization
• names
• numbers
• speaker labels, if used
• consistency of style
• missing words
• accidental repeated words
• unclear wording

Even if timing is perfect, spelling and grammar mistakes can make the subtitle file look unfinished.

11. Check Terminology and Consistency

For longer projects, terminology consistency is very important.

Check whether names, terms, titles, brands, locations and repeated phrases are written the same way throughout the file.

This is especially important for:

• series
• films
• training videos
• corporate projects
• educational content
• technical content
• multilingual projects
• client-specific terminology

If a term appears in multiple ways, choose one version and apply it consistently.

12. Check Subtitle Positioning

If your project uses subtitle positioning, review it before export.

Check whether subtitles appear in the correct area of the screen and whether positioning is used only where needed.

Subtitle positioning may be important when:

• text would cover important visual information
• subtitles need to avoid on-screen text
• speaker identification is needed
• project requirements specify subtitle placement
• a format supports positioning data

Keep in mind that different subtitle formats and players may handle positioning differently.

13. Check Subtitle Format for Export

Before exporting, confirm the correct subtitle format.

Sublandia Editor supports export formats such as:

• SRT
• TTML
• DFXP
• VTT
• ASS

Choose the format based on the delivery requirement.

For example, SRT may be enough for simple playback, while TTML, DFXP, VTT or ASS may be required for specific platforms, web workflows, styling or professional delivery.

14. Export a Project Backup Before Final Delivery

Before or after exporting the final subtitle file, consider exporting a full project backup.

Sublandia Editor supports .subpro project files.

A subtitle export is usually the delivery file. A .subpro file is a project backup that can preserve broader project data, including the project context, video, template and other project information.

For important work, export both:

• the final subtitle file
• the full .subpro project backup

Export is not just a button. It is the final step after review.

 FAQ

Should I export subtitles as soon as the text is finished?

No. Text completion is not the same as final review. Before export, you should check timing, sync, QC warnings, spelling, line breaks, export format and project settings.

What should I check before exporting subtitles?

Check sync, timing, overlaps, gaps, CPS, CPL, WPM, duration, line count, spelling, terminology, positioning, language, export format and project settings.

Does Sublandia Editor check errors automatically?

Yes. Sublandia Editor includes real-time validation for CPS, CPL, WPM, number of lines, minimum and maximum duration, gaps and overlaps.

Do QC warnings replace final review?

No. QC helps find technical and readability issues, but final review is still needed for language quality, context, natural timing and delivery readiness.

What should I do with yellow warnings?

Yellow warnings should be reviewed. Some may be acceptable in context, while others should be improved before export.

What should I do with red errors?

Red errors should normally be fixed before export because they usually indicate ruleset violations or serious timing/readability problems.

Why should I check FPS before export?

If FPS or video version is wrong, subtitles may drift out of sync or export with timing that does not match the intended video.

Should I check gaps before export?

Yes. Subtitle gaps should follow the selected ruleset and support clean professional timing.

Should I check overlaps before export?

Yes. Unintended overlaps should normally be fixed before export because they can cause playback, QC or delivery problems.

Should I export a .subpro backup?

For important projects, yes. A .subpro backup helps you save, transfer or restore the full project later.

What is the difference between subtitle export and project backup?

Subtitle export creates a file such as SRT, TTML, DFXP, VTT or ASS. Project backup creates a .subpro file that preserves the full Sublandia Editor project.

Which subtitle format should I export?

Export the format required by your client, platform or workflow. Sublandia Editor supports SRT, TTML, DFXP, VTT and ASS.

Why can exported subtitles look different in another player?

Different players and platforms can handle fonts, line breaks, positioning and styling differently, especially across different subtitle formats.
