Exporting for TikTok, Shorts and Reels
2026년 9월 13일 갱신
All three platforms want the same thing: vertical video, MP4, with audio, short. Simbounce exports exactly that from the browser. What is left to decide is quality, duration, and whether you want the file without a watermark, which is the only step that leaves your computer.
단계별 안내
- 01
Pick the vertical resolution
In the Export panel, keep the 9:16 proportion. 1080×1920 is the size the platforms display full screen; the physics does not change with resolution, only the sharpness. If the editor warns that the resolution is above what is recommended for your device, accept a smaller one or use the server render.
- 02
Let the duration end with the scene
The maximum duration is a ceiling, not the video's length: the file ends at the scene's natural finish if it comes sooner. A ceiling of 30 seconds suits almost every escape scene; the one-on-one duel usually asks for more.
- 03
Choose the frames per second
30 fps is what the platforms deliver on most devices and what produces smaller files; 60 fps makes motion smoother and doubles the encoding work. Both produce the same simulation — the rate changes how many frames are drawn, not the physics.
- 04
Export and check the result
The progress shows the phases: checking the device, encoding, assembling the file. Open the MP4 before posting and watch it to the end: what you see is what the platform will receive.
- 05
If you need the file without a watermark, render on the server
The Watermark-free path enters a queue, renders the same recipe with the same engine and returns the file with audio. It requires an account and credits, and the download link expires — download right away. The free plan can use the queue too, but gets the watermark.
Where the watermark appears
On the free plan, the file exported in the browser carries the watermark in the center of the frame. It is not a lock to work around: it is the price of unlimited rendering being free. The paid plan removes the watermark on the server render — and whoever has that right can still choose to include the watermark, in the corner, as a signature.
Browsers and what each one exports
Recent Chrome, Edge and Firefox and the current Safari export video and audio. Older Safari versions export video but do not encode audio, and the editor warns that the file will come out without a track. Firefox on Android does not encode video in any version; there, the path is the server render.
None of this changes the simulation. When a device cannot export, the recipe stays the same, and another device — or the server — produces the same video.
Why the platforms' interface matters
TikTok, Shorts and Reels draw buttons, caption and profile name over the video, and slightly crop the edges on some devices. The editor keeps the scoreboard, the names and the watermark inside a safe margin designed for that; when choosing theme and overlays, keep the subject in the middle of the frame, where nothing covers it.
A caption that helps the video get found
Write what happens — how many collisions, where the climax lands, how it ends — and not only hashtags. The numbers are in the seed search and on each scene's page on this site. And include the recipe, or a link to it: it is what lets someone reproduce the video, and it is what makes the video work for the channel after it is published.
