How to film vertical and horizontal video at the same time
Stop choosing between TikTok and YouTube: get a 9:16 and a 16:9 video from the same take, and frame the shot so both work.
By the Dualsy team ·
TikTok, Reels and Shorts are 9:16. YouTube and most websites are 16:9. Shooting wide and cropping later loses most of the picture, and shooting twice means doing every take twice. Recording both frames from one take avoids both.
Step by step in Dualsy
Choose DUAL CAM
One camera, two windows: the main picture and a second window with its own aspect ratio.
Set the main frame to 9:16
Tap the frame button until the guide shows 9:16. This is your TikTok, Reels and Shorts video.
Keep the second window at 16:9
The small window shows the wide frame of the same shot. This is your YouTube video.
Record once, keep both
Press record. When you stop, the take is saved as two files.
Landscape + portrait
One take, a 9:16 file and a 16:9 file.
Pro controls
4K up to 60 fps, 0.5x to 2x lenses, MOV or MP4.
Framing for both at once
- Keep the subject in the centre third: that part is in both frames.
- Leave headroom: the 9:16 frame is taller, the 16:9 frame is wider.
- Put text and graphics in the edit, not on set, so each version gets its own placement.
- Turn on the framing grid to keep the horizon level in both.
