How to prepare a Choicer Voicer dub for MP4
Choose a clean segment, captions, aspect ratio, and responsible sharing workflow.
Last verified: August 27, 2026
Choose the moment
A useful social clip usually needs a brief setup and a clear payoff. Mark a 15 to 30 second segment and retain a copy of the full recording.
Choose the frame
Use 9:16 for TikTok, Shorts, and Reels, 1:1 for square posts, or 16:9 for the complete scene. Keep important action and captions inside safe margins.
Understand the current tool
The Clip Maker previews layout and text locally. Final MP4 rendering requires a media pipeline and is not presented as active until the browser FFmpeg or server worker is connected.
Prepare the cleanest source
Use the original local recording when possible instead of re-recording a browser preview. Trim only after keeping a full copy. Listen with headphones for missing dialogue, echo, private notifications, or names that should not be shared.
Build for the destination
Choose 9:16 for TikTok, Shorts, and Reels, 1:1 for square feeds, or 16:9 for a complete scene. Keep faces, game action, captions, and the main joke inside safe margins because platform controls can cover the outer edge.
Add readable captions
Use short caption lines with strong contrast and enough time to read them. Check spelling, speaker changes, and whether captions disclose information a performer did not agree to publish. Preview the complete clip once without stopping.
Know the tool boundary
The Clip Maker currently previews framing, hooks, and caption styling locally. Treat a visible export control as active only when the browser media pipeline reports support. If final MP4 rendering is unavailable, use the preview to plan the clip and finish it in a trusted editor rather than claiming that the site created a file.
Check the final file rather than the preview
A layout preview does not prove that the exported MP4 contains synchronized audio, captions, or the intended frame. Open the final file in a separate player, watch from beginning to end, and confirm duration, orientation, volume, caption timing, and file size. Test once with headphones and once at a normal speaker level. Keep the original recording until the published version has been checked; re-encoding an already compressed social download usually reduces quality.
Share with consent and useful context
Ask every recognizable performer before uploading. Identify the game or Pack accurately, credit the Pack creator when required, and avoid presenting a fan-made Pack as official. A short caption can explain the scene, performance challenge, and whether the clip was a first take without exposing private names or conversations. Platform upload buttons are not connected to this website, so TikTok, YouTube, Facebook, and X sharing links prepare destinations or page URLs rather than silently publishing a local recording.
