What aspect ratios does Bonega output, and can it make vertical video?
Two shapes: 9:16 portrait and 16:9 landscape, chosen before generation. 9:16 is what TikTok, Instagram Reels and YouTube Shorts expect, so a portrait generation is upload-ready with no crop, no letterbox and no re-frame — the shot is composed for that frame rather than cut down to it, which is what makes a cropped landscape clip look wrong. Length is independent of shape: any clip over 15 seconds is generated as a chain of segments and merged into one MP4, at 4.125 credits per second in either orientation.
Choosing the shape
- 9:16 — TikTok, Instagram Reels, YouTube Shorts, Snapchat.
- 16:9 — YouTube, a site hero, anything watched on a desktop.
- The choice is made at generation time. It is not a post-processing crop, so switching shape means generating again.
Cost and length do not change with orientation
A vertical second and a landscape second cost the same 4.125 credits. A 120-second request is the ceiling for one generation in either shape, and extending a finished video appends up to another 120 seconds each time with nothing capping the total.
Starting from a photo you already have
Upload a portrait photo and generate 9:16 to keep the framing you shot. Uploading a landscape photo and asking for portrait means the model has to invent the top and bottom of the frame, which is the single most common cause of a result that does not match the source.
What this means for you
Choose the ratio at generation time, not in the edit. Cropping a landscape render to 9:16 throws away the part of the frame the model composed around, and the result usually looks like a crop. If you need one shot in several ratios, generate it more than once rather than reframing, and treat the extra seconds as part of the brief.
Frequently Asked Questions
Can I generate vertical video for TikTok directly?
Yes. Choose 9:16 before generating and the output is already in TikTok's shape — no crop or re-frame step.
Does vertical video cost more than landscape?
No. Both are 4.125 credits per second of video, rounded up.
Can I change a finished video from landscape to portrait?
Not by cropping inside Bonega. Orientation is chosen before generation, so a different shape means generating again — which is also what keeps the composition correct for the new frame instead of cutting the sides off.
