Vizard Agent

How to take the filler words out of your subtitles

Last updated 2026-10-10 · 2 min read

List the filler words and where they appear, and tell Vizard Agent the picture must stay unbroken. Vizard Agent removes them from the captions at those exact timecodes, tracks down the brand typefaces the design needs, and rebuilds the subtitles without touching the footage or the audio.

What do you type into Vizard Agent?

Say what must not change alongside what should. Otherwise Vizard Agent will reach for the obvious fix, cutting the filler out of the audio, which is usually right and is exactly what a continuous shot rules out. Give timecodes so the correction is exact, and name the typefaces so the rebuilt captions match the rest.

Prompt

Fix only the subtitles on this reel: remove the filler words "[um]" and "[er]" at [00:15, 00:34, 00:40, 00:49]. Keep [the speaker] in frame from start to finish. Do not cut the picture. Captions in [the brand typefaces].

What does Vizard Agent actually do?

Automatic captions are faithful, which is the problem: they write down every "um". If the shot has to run unbroken, the fix is in the text, not a cut. Most of the effort goes into finding the real brand fonts, because rebuilt captions in a near-enough typeface look wrong beside the untouched ones. In the session behind this article it:

When does this not work well?

Correcting captions without touching the audio opens a gap between what is heard and what is read. Remove too much and the reading stops matching, and with heavy filler Vizard Agent will suggest cutting the audio after all. Some brand fonts are licensed and can't be downloaded, and burnt-in captions have to be rebuilt.

Common questions

Does the audio change? No. Vizard Agent edits the captions only, leaving the speech and the picture as they are.

What if my brand font is not installed? Vizard Agent goes looking for it rather than substituting something that looks close.

Is it worth removing every single filler? No. Vizard Agent leaves the ones nobody notices, so the captions don't read like a script.
