Video tips

🎬

16:9 is the standard for YouTube, Netflix, and most modern video. 9:16 is used for vertical (mobile) video on TikTok, Reels, and Stories.

📐

Use "Ratio → Dimensions" mode: enter 16:9 and a known width (1920) to instantly get the correct height (1080).

💡

Cinema scope (2.39:1) is the "letterbox" format. If you see black bars at top/bottom, your video is wider than the 16:9 container.

🎞️

For DJI drones, the native aspect ratio is often 4:3. Export in 16:9 to crop to standard widescreen, losing some top/bottom pixels.
