FAQ
Frequently asked questions
Is the video editor free?
Yes. The video editor is free for everyone on Promly, the free plan included. Sign up free (15 Pixels, no credit card) and open it from the Studio. Pixels are only spent when you generate new images or clips to edit.
Do I need to install or download anything?
No. The editor runs entirely in your browser: there's nothing to download, install or update. It works on modern desktop browsers.
What can I do in the editor?
Trim and split clips, arrange them across multiple tracks, layer images and audio over video, reorder your timeline, and export the finished video.
Can I make TikTok and Instagram Reels with it?
Yes. Edit vertical (9:16) video on the timeline and export it ready to post to TikTok, Instagram Reels and YouTube Shorts.
Can I use my own footage?
Yes. Upload your own video clips, images and audio, or use images and reels you generate in Promly. Mix and match on the same timeline.
How is this different from the AI Reel Maker?
The AI Reel Maker is free and auto-assembles a reel from your images with transitions in one click. The video editor, also free, gives you a full timeline to trim, split, layer and fine-tune by hand, for when you want manual control.
