    Questions about resizing video ads

    How do I convert a vertical video to horizontal?
    Upload your 9:16 clip, choose Expand, and pick 16:9. AI generates new picture on the left and right of your footage, so the whole frame is filled with matching scene instead of black bars or blur.
    Can I resize a 9:16 video ad to 16:9 for YouTube?
    Yes. That is the most common job here. Your vertical ad becomes a widescreen version for YouTube, display video and connected TV, and you keep the original for Reels, TikTok and Shorts.
    Does it work the other way, from 16:9 to 9:16?
    Yes. Pick 9:16 and AI adds new picture above and below your footage, so a widescreen spot becomes a full-screen vertical ad.
    Is anything cropped out of my ad?
    No. Your original footage stays whole in the middle of the new frame. With the recommended model, only the new space around it is generated, so your product, logo and on-screen text stay where you put them.
    How long can my ad be?
    Each run reshapes up to 8 seconds of footage, from an MP4, MOV or WebM file up to 200 MB. A 6-second bumper fits whole, and you can trim a longer spot to its strongest moment.
    How much does it cost?
    You buy credits in packs from $4.99, and each run spends them. There is no subscription.
