Plan an export before you render it. Check the aspect ratio and orientation of any resolution, estimate how large a file will be at a given bitrate, and turn a short MP4 clip into a GIF without uploading it anywhere.

Use ToolHow these tools can help
Rendering twice because a file was too large or the frame was wrong wastes more time than any editing shortcut saves. Plan the export first: check the ratio, estimate the size, and convert short clips without uploading them.
- Estimating whether a 60-second export will fit a platform's upload limit.
- Confirming that a resolution really is 9:16 before you render.
- Turning a three-second clip into a GIF for a chat or a page.
- Choosing a bitrate that survives platform re-encoding.
