Social media is 9:16, but live production is 16:9. Grabyo’s new intelligent reframing tools allow you to bridge that gap instantly. By combining AWS-powered AI with manual keyframing, editors can create professional vertical clips without leaving the live clipping page.
Core Functionalities & Logic
Core Functionalities & Logic | Controls | Functionality |
Manual Keyframing | Click to 'pin' the action at a specific time. | Creates anchor points for Linear Interpolation. |
Mouse Tracking | Hold 'X' and follow the action with your cursor in real-time. | Records coordinates as you move your mouse, extracts keyframes for fine-grained editing. |
Smart Tracking | Click the 'smart tacking' button in the keyframe sidebar. | Uses AWS Elemental Inference for frame-by-frame path analysis, extracts keyframes for fine-grained editing. |
Smoothing | Keeps the camera movement fluid and natural. | Employs Linear Smoothing to connect keyframes mathematically. |
How smoothing works
When you use AI or Mouse Tracking, the system generates a large amount of raw data (one data point per frame).
Grabyo uses the RDP (Reumann-Douglas-Peucker) Algorithm to "clean" this data. It strips away the "noise" and jitter of a shaky hand or AI twitch, leaving behind a simplified set of editable keyframes. This gives you a professional path that you can still tweak manually.
Interpolation is then added between these frames to automatically move the frame. For linear interpoltion we add a linear algorithm to move the frame from keyframe A to keyframe B.
For easing, we use a CR spline to soften harsher-looking movements such as changes in direction or quick speed changes.
✅ Tips:
Primary Anchors: Place keyframes where the action's direction or speed changes. This will be performed automatically when using mouse tracking or AI smart tracking.
Secondary Details: Add detail keyframes only when needed; the interpolation should do the heavy lifting. Creating too many keyframes can cause jitter. Fewer points result in smoother, more cinematic movement.
Use the shortcut keys 'v' and 'b' to jump between keyframes, enabling quick review of each keyframe's position.
To ensure clean cuts between shot changes, place one keyframe on the last frame of the first shot and another on the first frame of the second shot. This prevents the sliding effect between shots.
📕 Note: The initial release includes beta keyframing and mouse tracking; AI tracking and keyframe playback will be added shortly. For details, contact your account manager or support at help@grabyo.com.
