Question 1

What video formats does Portrait AI support?

Accepted Answer

MP4, MOV, and MKV files up to 5 minutes long. The video must be landscape (16:9 or wider), minimum 640x360 resolution. We recommend 1080p H.264 for the best results.

Question 2

Is Portrait AI really free?

Accepted Answer

Yes. Portrait AI is free to use with a Google sign-in. There are no hidden charges, no credit card required, and no limits on the free tier beyond the 5-minute video length.

Question 3

Does Portrait AI add a watermark?

Accepted Answer

No. Portrait AI does not add any watermarks or branding to your converted videos — not on the free tier, not ever. The output is clean, ready to post.

Question 4

How does AI subject tracking work?

Accepted Answer

Portrait AI uses computer vision to identify subjects (people, ball, action) in each frame of your video. It generates a smooth crop path that follows the action across the landscape frame, then renders a portrait version where the subject stays centered.

Question 5

What platforms can I convert for?

Accepted Answer

Portrait AI outputs video in 9:16 (TikTok, Reels, Shorts, Snapchat), 4:5 (Instagram Feed), and 1:1 (Square, Twitter, LinkedIn). One upload, multiple output formats.

Question 6

Can I use it for sports footage?

Accepted Answer

Yes — Portrait AI was built with sports in mind. The AI tracks the ball and players across the field, making it ideal for football, cricket, basketball, combat sports, and youth sports highlights.
