When you export your finished project from Create it will be an MPEG-4 (.mp4) video file and the frame rate will usually be 30fps.
The standard free output resolution (quality) is 480p (SD).
You also have the option of exporting a higher quality 720p (HD) or 1080p (Full HD) version of your video by making a one-off payment (which works for one export) or by upgrading to the Create Premium Plan or Business Plan (which works for unlimited exports). These plans also give you access to 5 stock video or audio assets a month.
To upgrade to a plan or make a one-off payment, click UNLOCK next to the options in the quality dropdown menu when exporting.
