A caption can fit the character limit and still look awkward. A long word, a wide font or a break in the middle of a phrase can leave one line crowded and the next nearly empty. Treat character counts as a starting point, then inspect the actual text at its final size.
In TCaption, two settings shape the result: characters per caption groups words into timed segments, while characters per line adds line breaks within those segments.
Choose how much text appears together
Characters per caption changes the amount of text assigned to one caption. A lower value generally produces shorter groups. A higher value lets more of a sentence appear together, which may require more space on screen.
Start with a passage that contains both short and long sentences. Listen while reading. If captions change so quickly that you cannot take in the phrase, review the grouping. If they cover too much of the picture, reduce the group size or adjust the layout.
Punctuation and sentence-splitting options also influence the groups. Check the caption options reference for the controls available in the extension.
Choose where each caption wraps
Characters per line affects wrapping inside a caption. A small limit can turn a single segment into three lines even when you expected two. Increasing that limit may reduce the line count, but the text still needs to fit the picture.
Consider this phrase:
| A useful break to try | A break to reconsider |
|---|---|
| Fully customizable / captions | Fully / customizable captions |
| in Premiere Pro | in Premiere / Pro |
Here, a slash indicates a line break. The first examples keep related words together. They are starting points, not rules for every composition. A narrow portrait frame, large type or deliberate emphasis can call for a different arrangement.
The faint | in TCaption's transcript shows a planned line break. It stands in for a space in the editor; it does not become a visible bar in the final caption.
Use the maximum line count as a check
The transcript's maximum line count reports the largest number of lines among the current caption segments. If you want two-line captions and the counter says three, at least one segment needs review.
The counter is a display, not an automatic constraint. Adjust the character settings, locate the longer phrases and inspect the preview again. Check the styled result too: font width, size, letter spacing and backgrounds all affect how the same wording looks.
Keep enough room around the text
Line spacing separates the baselines of stacked text. Background padding controls the room around a box. Increasing one does not replace adjusting the other. Review both when highlights seem cramped or adjacent lines appear to touch.
Set the caption position with the composition in mind. Check faces, existing titles and areas covered by the destination platform's controls. Preview at the actual delivery size, especially for a portrait video viewed on a phone.
Recheck edited captions after regrouping
Changing character counts rebuilds groups from timed words. If you substantially rewrote a caption, the new text may no longer match the original word timings. Save a JSON transcript backup before major changes, and listen through the affected section afterward.
When the transcript looks right, render a sample in Premiere to check the selected template, font and effects together. The HTML preview is helpful for layout, but the Premiere render is the place to inspect the finished treatment.
For the complete process, follow the animated caption workflow. If you are still choosing an editor, read the comparison of TCaption, CapCut and VEED caption workflows.
