To send subtitles with a video, deliver the exact video export and its matching subtitle files together. Label the languages and version clearly, test playback, and share the package through FileFlap with instructions for the recipient.
Choose the kind of subtitle delivery
A separate subtitle file, often called a sidecar, lets a compatible player load captions alongside a video. Burned-in subtitles are part of the visible picture and cannot simply be switched off. Some workflows also support subtitle tracks inside the video container.
Ask what the recipient's editing, playback, or publishing system accepts. Do not assume a subtitle format supported by your player will work everywhere. If you provide a burned-in review copy, label it separately from the clean master and editable caption files.
Keep filenames and versions aligned
Use a shared base name, such as Launch_v04.mp4 and Launch_v04_en.srt. Add clear language identifiers for each translation and explain them in the delivery note. Where a playback system requires exact filename matching, follow its naming rules and put other language versions in clearly labeled folders.
Any edit that changes the timing of the video can affect subtitles. Adding an opening slate, trimming a pause, or replacing a scene can create drift or an offset. Treat the video and captions as a versioned set rather than updating one independently.
Check timing and readable text
- Load the intended video and subtitle file in the target workflow.
- Check the beginning, middle, and end for synchronization.
- Inspect accented characters, punctuation, and line breaks.
- Check speaker labels and sound descriptions when included.
- Review long captions for comfortable reading time.
A consistent offset and timing that gradually drifts are different problems. Confirm that the captions were created for this precise export before adjusting timestamps. If a conversion is needed, retain the original subtitle file and review the converted result.
Explain what to download and open
Package the video, subtitles, and a brief README together. In your delivery message, identify the master, available languages, and how to enable captions in the intended application. A browser preview may not load a separate subtitle file automatically, so test the downloaded files before diagnosing a missing-caption problem.
Can a ZIP archive add subtitles to a video?
No. It keeps the related files together for delivery. The recipient still needs to extract them and load the subtitles, or import them into compatible editing or publishing software.
