TikTok, Reels and Shorts: 9:16, 1080 x 1920. Instagram post: 1:1 (1080 x 1080) or 4:5 (1080 x 1350). YouTube and most players: 16:9, 1920 x 1080.
Crop fills the whole screen, which looks best on phones, but cuts off the sides; move the crop to keep the person or subject in the frame. Bars keep the whole picture with black above and below.
Yes: our animated captions tool writes word-by-word captions for TikTok and Reels from the speech in your video.
No. The video is read and processed by your own browser, with your computer or phone doing the work. Nothing is sent to our servers, so it is safe for private videos too.
Chrome, Edge, Opera and Brave (version 94 or newer), Safari 16.4 or newer, and Firefox 130 or newer, on a computer or a phone. A computer is much faster for long videos.
