If you already own a video editor, cropping a second aspect ratio out of your footage feels free — you shot one file, why not just export it twice? In practice, that "free" option has a real time cost that's easy to underestimate until you're doing it every week.
What the after-the-fact crop workflow actually involves
- Import the original footage and duplicate your timeline so the vertical edit doesn't touch your landscape master.
- Reframe every single cut to a 9:16 crop — if your subject isn't centered in the original shot, this means manually repositioning the crop per cut, not just resizing once.
- Keyframe pans for movement — any time your subject walks, turns, or the camera moves, a static crop will lose them, so you need to animate the crop position to follow.
- Re-check audio levels since a tighter crop can change your instinct about what's "in frame" versus what's just implied by sound.
- Render a second export at the new resolution and aspect ratio, on top of your original render.
None of these steps are hard individually. Multiplied across every video you publish, they add up to a second, smaller edit for every piece of content — indefinitely.
What recording both formats live skips
When portrait and landscape files are captured simultaneously during the shoot, steps 2 and 3 above don't exist — there's no crop to reframe or keyframe, because each file was already framed on purpose the moment it was recorded. What's left is the same trim-and-caption pass you'd do for a single video anyway.
| Step | Crop-after-the-fact | Record both live |
|---|---|---|
| Duplicate timeline | Required | Not needed |
| Reframe each cut | Required | Not needed |
| Keyframe pans for movement | Required for any motion | Not needed |
| Second render/export | Required | Files are already separate |
| Trim & caption | Required | Required |
When cropping after the fact still makes sense
If you're repurposing old footage you didn't shoot with this in mind, or pulling a single vertical highlight out of a much longer landscape video, cropping afterward is still the right tool — there's no "redo the shoot" option for existing footage. The live-recording approach mainly pays off for new shoots where you already know both formats are needed.

DualFrame records native portrait and landscape video from the same take, so new shoots skip the reframe-and-keyframe pass entirely.
