An export should match a destination and a viewing situation. This guide uses a 15-second vertical motion graphic as an example and separates current official requirements from our suggested working settings. Platform rules can change; confirm the chosen placement when you publish, especially when switching between an organic post and a paid advertisement.
Choose the canvas before you polish
For a vertical social version, 1080 × 1920 at 9:16 is a practical working canvas. For a landscape presentation, 1920 × 1080 at 16:9 may be more appropriate. These are delivery choices, not a promise that every platform requires them. Recompose a horizontal scene for vertical viewing: stack the headline and focal object, shorten long lines, and move secondary details. Cropping a finished landscape file can remove the product or call to action. Keep separate composition names so the two versions do not overwrite each other.
Check the rule for the actual placement
YouTube documents square or vertical videos of up to three minutes as Shorts under its current upload eligibility rules. TikTok’s Non-Spark auction in-feed ad specification recommends 9:16 and permits a vertical minimum of 540 × 960; that is an advertising specification, not a universal organic-post rule. For Instagram Reels, use the current upload interface and Meta help for your account and placement; we do not state an unverified duration or file-size limit here. Keep important text away from controls and captions, then inspect the platform preview because interface overlays vary.
Use a compatible delivery file
For a conventional SDR social delivery, MP4 with H.264 video and AAC audio is a useful starting choice supported by YouTube’s recommendations. Use a frame rate consistent with the source; increasing a finished 30 fps animation to 60 fps does not add designed motion detail. Remotion exposes encoding controls separately from composition dimensions. Avoid changing several compression options at once. Render a short section containing small type and fast movement, compare it with the source, then choose a setting that preserves those details at an acceptable file size.
Keep export settings with the file
Write down the composition, dimensions, frame rate, duration, codec, and final filename. In the open-source toolkit, select the actual Remotion composition in Studio or the render CLI; an example build script can still target the repository’s sample video. This site’s downloads use a different local workflow, so follow the included instructions for HyperFrames. A browser preview or shared HTML link is not an MP4 export. Check the output in a media player and inspect file properties rather than assuming that a .mp4 extension proves the requested encoding or size.
Review on a phone and after platform processing
Watch once at normal speed with sound, then once muted. Check the opening frame, longest headline, smallest label, subtitle timing, logo edges, and final action. Make sure a person can understand the message without stopping the video. Upload as a draft or private item when the platform supports it, wait for processing, and inspect the platform’s version for cropping, compression, or covered text. If something fails, return to the source and export again. Keep the approved master, platform-specific versions, and the publication caption together for the next update.
Your next step
Exporting is finished when the delivered file and its platform preview remain readable and correctly framed. A successful render command is only one step in that check.
