Made with HeyGen Avatar IV in Shorz
Finished videos made in Shorz with HeyGen Avatar IV: one generated photo and a script in, then captions, AI B-roll, emojis and music added by Shorz. Press play for sound.
Script: “Three habits that literally doubled my productivity. One: I plan tomorrow, tonight. Five minutes, three priorities, done. Two: my phone lives in another room until lunch. Sounds extreme. Works every time. Three: I work in fifty-minute sprints, then I take a real break. Walk, water, stretch. Steal just one of these this week, and watch what happens.”
Script: “Stop doing crunches. Seriously. They pull on your neck and only hit a small part of your core. Do this instead. Planks: thirty seconds, squeeze everything, breathe. Then dead bugs: back flat on the floor, opposite arm and leg, slow and controlled. Finish with bird dogs, ten each side. Three rounds, ten minutes, and your core will thank you. Save this for your next workout.”
HeyGen Avatar IV at a glance
Avatar IV is HeyGen's photo-avatar engine: it lip-syncs a single still photo of any person to an audio track. Shorz drives it with the same per-sentence avatar pipeline as Kling and OmniHuman, so you pick it in the avatar model dropdown and everything else — script, voice, captions, B-roll, music — works the same. It's the cheapest avatar model per second in the app.
