How do I create a new project in Filmora with the correct aspect ratio?
Choose the project aspect ratio before editing and match it to the platform where the video will be published. Use 16:9 for most landscape YouTube videos, 9:16 for vertical short-form video, and a custom setting when the delivery specification requires another frame.
Which Filmora aspect ratio should you choose?
Use 16:9 for standard landscape videos, tutorials, presentations, and most long-form YouTube content. Use 9:16 for TikTok, Reels, and Shorts when the subject is framed vertically.
Square 1:1 can work for some social feeds, while 4:5 gives portrait content more screen space in a feed. The important rule is to choose the delivery frame first so you can compose titles, faces, and graphics inside the correct canvas.
What happens if the source video has a different ratio?
Filmora may show crop, fit, or letterbox behavior depending on the project and clip settings. Reframe the subject manually rather than accepting a crop that cuts off faces, product details, or subtitles.
Do not stretch a landscape clip to fill a vertical canvas. Crop, reposition, or use a designed background so the image keeps its natural proportions.
