Exporting your video
The preview in your browser is not a file yet — one prompt turns it into an mp4 you can post
The preview studio plays your video, but it isn't a file. Nothing to upload, nothing to send. Rendering fixes that: it turns the preview into a real mp4, and it's one prompt.
The one move
When the video looks right in the player, paste:
Render the video to an mp4 in the project folder, and tell me the full path
to the file when it's done.That's it. Your agent runs the render and tells you where the file landed.
What to expect
Rendering builds the file frame by frame — every frame of your video gets drawn and encoded. A thirty-second video takes a few minutes, longer than the video itself. That's normal, not a sign something is stuck. Let it finish; your agent will report back with the path.
Where the file goes next
The mp4 is ready to upload as-is. X, YouTube and LinkedIn all take the horizontal file directly — no conversion, no export settings, no editor in between.
Posting to Shorts, Reels or TikTok too? Those want a vertical cut of the same video: One video, three formats.
Changed something after rendering?
Just render again. The old file is not precious — a render costs a few minutes, so tweak the video, paste the same prompt, get a fresh mp4. Render as many times as it takes.
