How to rebrand a video after a product name change
Upload the video and give Vizard Agent the old name and the new one. Vizard Agent finds every mention in the speech and on screen, prepares a clean voice sample for each speaker, generates the new word in each of their own voices, and replaces it at the exact word timings.
What do you type into Vizard Agent?
Say "any references" rather than listing the ones you happen to remember. Vizard Agent searches the transcript and the frames for every occurrence, which reliably turns up the two in the middle that nobody could recall. Spell both names exactly, and add a pronunciation note if the new name reads ambiguously.
Prompt
What does Vizard Agent actually do?
Vizard Agent finds every mention in two places at once, the speech and the screen, because both have to change or the inconsistency is more distracting than the old name was. With three speakers, one generated replacement dropped into all three places sounds like three people being interrupted by a fourth. In the session behind this article it:
- Checked the video's duration and parameters: 225.39 seconds of 3840x2160 HEVC at 23.976fps, with three speakers.
- Extracted the transcript and checked the exact interval of every mention of the old name.
- Got a description of the scenes to find the on-screen occurrences, then took frames around each mention and the closing card.
- Reviewed those frames and the end card by eye to check the logo.
- Checked the available methods for replacing speech and prepared a clean voice sample for each speaker.
- Generated the new name in each speaker's own voice in turn and found the exact word timings to cut it in, leaving the rest of the video as delivered.
When does this not work well?
Replacing a word inside finished audio and frames has real limits. A one-syllable name replacing four disturbs the rhythm, and a mention under another voice can't be isolated cleanly. Moving type has to be rebuilt rather than patched, a new logo has to be supplied as artwork, and a legal rename may need more changed than the name.
Common questions
Do I need the original project file? No. Vizard Agent works from the finished video you already have.
Whose voice says the new name? Each speaker's own voice. Vizard Agent builds a clean sample per speaker before generating.
Does the on-screen text change too? Yes, if you say so. Vizard Agent checks the frames and the end card as well as the speech.
