Frequently Asked Questions

What is the best resolution for TikTok?

1080x1920 pixels is the recommended resolution for TikTok. This provides Full HD quality in the 9:16 vertical format. TikTok will accept other resolutions but may crop or add black bars.

Is 9:16 the same as 16:9 rotated?

Yes! 9:16 is simply 16:9 turned on its side. If you have a 1920x1080 (16:9) video, rotating it gives you a 1080x1920 (9:16) frame. The math is identical, just with width and height swapped.

Why is vertical video so popular?

Most people hold their phones vertically most of the time. Vertical video fills the entire screen without requiring rotation, creating a more immersive, full-screen experience. Studies show vertical videos have higher completion rates on mobile.

Can I convert 16:9 video to 9:16?

Yes, but you'll lose significant content. You can either crop (losing the sides), add blur/color bars on top and bottom, or use AI tools to expand the frame. The best approach depends on your content.

What frame rate should I use for 9:16 video?

Most platforms accept 24-60fps. TikTok and Instagram Reels work best at 30fps. YouTube Shorts supports up to 60fps. Higher frame rates (60fps) are good for action content but increase file size.
