What this action does
one loaded cross into the bag, full power, clean reset. You give the app a single photograph and it generates a short clip of that movement, roughly 5 seconds long. Nothing is filmed and nothing is recovered: the motion is produced from the one frame you supply.
What photo works best
A cross travels forward from the shoulder, so the arm has to start somewhere findable: hands in view, elbows clear of the ribs, nothing crossing the chest. Waist up is workable and full length is better, since the weight shifts off the back foot. The camera sits low and snaps forward with the punch, blurring whatever is behind you, so a plain wall costs you nothing at all. Avoid a photograph where you are holding something in one hand, because that hand becomes the one throwing the punch.
What to expect
One photograph goes in and a short clip comes out. It is generated rather than filmed, so run it twice if the first attempt puts a hand somewhere strange; the second version will not be identical.
If the result is not convincing, the fix is almost always the photograph rather than the settings. Reshoot it wider, get more light on the face, and move the arms clear of the body. The rest of what decides the result applies to every action here, and the limits apply to this one too.
Common questions
- What kind of photo works best for Heavy Bag Cross?
- Heavy Bag Cross builds about 5 seconds of movement out of your photograph, and the one frame you choose is the entire input. Whatever has to appear in the result has to be in the shot, so frame wide enough to take in everything the movement touches, keep the subject sharp and clearly separated from what is behind them, and get even light onto the face and the hands.
- How long is the video?
- About 5 seconds. That is what the default video model in the app's catalogue is configured to produce, and it is the same for every motion action in the library.
- Do I need a subscription to use Heavy Bag Cross?
- No. Heavy Bag Cross is not marked as a subscription only action in the app's catalogue. AI Video is free to download, and generating a result uses credits, which are bought as a pack or come with a subscription.
The right action for the photo beats the popular one
Every movement and every style in the library is written up the same way, so you can check whether the picture in your camera roll actually suits it before you spend a credit.
