What Cannon Basket Actually Is
Cannon Basket is a video formatting technique that splits a single video frame into multiple smaller panels arranged in a grid pattern. It's most commonly used to adapt widescreen horizontal footage for vertical or square platforms without losing the original resolution. Instead of just letterboxing or cropping, you're rearranging the source material into a multi-panel layout that fills a vertical frame. The technique became popular on YouTube as a workaround for the Shorts vs. long-form format split. When a creator wants to post a clip on Shorts but the horizontal video feels too narrow, they use a cannon basket layout to reclaim screen space. Think of it as a cinematic grid overlay rather than a simple crop.
How to Create a Cannon Basket Layout
Here's the practical workflow. You need a video editor with keyframing and transform tools. DaVinci Resolve works fine, and so does Premiere Pro. CapCut can do it too if you're mobile-first. The basic steps are: Import your source clip onto the timeline. Duplicate it three or four times so you have multiple layers stacked vertically. On each duplicate, scale and position the clip so the panels sit side by side or staggered within the vertical frame. If your source is 16:9 and your target is 9:16, each panel typically ends up taking up about half the width of the frame with another panel beside it or below it depending on your grid choice. The trick is matching motion across panels. If your original footage has camera movement, each duplicated panel needs to move identically. That means keyframing the position on each layer separately or using a shared adjustment layer. I spent two hours on a single thirty-second clip once because I forgot to lock the movement between layers and the panels ended up drifting at slightly different speeds. The fix was grouping all the duplicate clips into a compound clip first, then duplicating the compound instead of the original timeline tracks.
When Cannon Basket Works and When It Doesn't
The layout works best with slow-moving or static shots. Think talking head videos, interview clips, or scenes where the camera isn't panning aggressively. If your footage has fast pans or rapid zooms, the grid can look jarring because viewers' eyes are tracking motion across panels that don't actually connect visually. I learned this the hard way on a driving shot. The horizontal pan looked fine in landscape but splitting it into a three-panel vertical grid made the viewer feel like they were watching three separate cars passing by at once. Total disconnect. I ended up just letterboxing that clip instead. Common pitfall: people tend to scale each panel too large. If your panels fill the entire frame with no gaps, you lose the visual separation that makes the grid readable. Leave a thin dark gap between panels or use a subtle background to frame them. That gap is usually 3 to 5 percent of the total frame width. Another issue is audio. The cannon basket only affects the video track. If you're pulling a segment from a longer video, you'll need to make sure the audio is clean and doesn't have sudden volume jumps between sections. Audio ducking or a simple gain normalization pass helps avoid the punchy jump cuts that happen when panels change mid-sentence.

Export Settings That Matter
Resolution should match your target platform. For YouTube Shorts, 1080x1920 is standard. Export at 30fps or 60fps depending on your source. Keep the bitrate at least 15 Mbps for 1080p to avoid compression artifacts blurring the panel edges. If you're using DaVinci Resolve, the Deliver page settings I use are H.264, maximum quality, and Enable Render at Maximum Resolution turned on. Prem users should check Render at Full Resolution in the export dialog. The canvas aspect ratio should be set to 9:16 before you start placing panels. If you set it after, everything shifts and you waste time readjusting. I always confirm the sequence settings first, then build the grid.
Alternatives If Cannon Basket Isn't Right
Not every clip benefits from the grid treatment. If your footage is heavily motion-tracked or has rapid scene changes, the format adds more work than value. In those cases, a simple center-crop or safe-area framing often looks cleaner. There's also the two-panel split where you stack two horizontal clips vertically instead of a three or four panel grid. That approach is faster to produce and works well for dialogue-heavy content where the viewer's attention is already focused on the speaker. If you're doing this repeatedly, consider building a template project with pre-placed panels and guide lines. One setup took me about forty-five minutes the first time. The second time with a template, it was under five minutes per clip. That kind of efficiency matters when you're trying to repurpose hours of footage into short-form content.
