What You'll Learn
Using the Region of Interest tool
To pan-crop in After Effects, you can use the Region of Interest tool. This tool allows you to make a freely formed crop inside your video composition. With it, you can change the aspect ratio of your video or crop out unwanted elements on the edges of your frame.
To use the Region of Interest tool, first select it. It is located right above the composition panel. Then, select the crop that you want to make in your video. Make sure to take your time with this step to ensure that your aspect ratio is correct and that you haven't accidentally cropped out any desired aspects of your video. Consider basic videography concepts like the rule of thirds and how movement in the composition will flow once everything is complete.
After you've made your selection, you can make further adjustments to the size of the frame by inputting specific dimensions. You can find the new video size by going to Composition > Composition Settings or by using the CMD + K shortcut. In the window that appears, you'll see the height and width of your video in pixels, and you can tweak the size of the frame as needed.
It's important to note that any full video cropping changes you make in After Effects will apply to the entire timeline and the exported footage. Therefore, proceed with caution if you're working with multiple layers and want to preserve portions of the video that you're not directly working with. Additionally, keep in mind some common problems that can occur, such as the wrong aspect ratio, effects no longer working properly, or awkward framing after cropping.

Cropping a single layer with a mask
Drawing a shape inside a layer will automatically create a mask that can be adjusted and animated to crop elements. You can also use the Node Tool to edit the shape's paths and create interesting crop shapes. If you are using Linearity Move, you can animate marketing assets by switching to Design Mode and selecting the Shape Tool in the Toolbar on the left.
Masks are a great way to improve performance in After Effects by creating layers that are only as big as they need to be. By cropping layers down, After Effects will not waste time processing unused pixels. You can calculate the mask size from a single frame, the composition work area, or the layer's duration.
Additionally, you can use the Track Matte feature to crop out one layer above or below a Shape layer, but it will apply an Alpha mask effect, altering the image.

Adjusting the frame of the entire video
Adobe After Effects is a popular visual effects tool used for video editing. It offers various video crop tools that can help frame footage, zoom in on points of interest, and apply effects. Here is a step-by-step guide on how to adjust the frame of an entire video using the Region of Interest Tool and the Pen Tool in After Effects:
Using the Region of Interest Tool:
First, launch After Effects and import the video you want to crop. Then, follow these steps:
- Click on the Composition tab and select the Region of Interest Tool.
- Create a rectangle around the area you want to crop by dragging the tool. You can also modify and adjust the edges of the video as needed.
- Once you are happy with the selection, go to Composition > Crop Comp to Region of Interest in the main menu. This will crop the composition to the selected area and change the size of your video.
Using the Pen Tool:
The Pen Tool is another feature in After Effects that allows you to crop a video accurately. Here's how to use it:
- Open After Effects and import the video you want to crop.
- Select the Pen Tool from the Tools panel in the upper left corner.
- Use the Pen Tool to draw a shape around the subject or area you want to crop. The mask doesn't have to be precise, as you can fine-tune it later.
- Use the Select Tool to adjust the shape of the crop. Click and drag to add points and handles to modify the mask's curve.
- Once you are satisfied with the crop area, press Enter to finalize the trim.
Additional Tips:
- If you need to make fine-tune adjustments to the height or width of your footage, you can do so by moving the icons on the croplines.
- To find out the exact dimensions of your video, go to Composition > Composition Settings. Here, you can see the height and width in pixels and make further tweaks to the frame size.
- If you want to crop multiple layers together, you need to combine them into a single layer or use advanced techniques like placing your mask beneath all the layers you want to crop.
By following these steps and utilizing the Region of Interest Tool and the Pen Tool, you can effectively adjust the frame of your entire video in After Effects.

Cropping videos for layering
To do this, first select the layer you want to crop or mask, and then select the shape tool or pen tool in the top left. Alternatively, you can use their hotkeys (Q and G, respectively). Next, use either tool to select the specific crop lines for the layer, whether that's a square, rectangle, or a custom shape you create by hand.
You can also use the Region of Interest tool to crop your video. To do this, select the Region of Interest tool at the bottom of the Composition panel, then click and drag to create your area selection. If you want to start over, press Alt or Option and click on the Region of Interest icon again to reset the selection.
Another option is to use the BCC UpRez effect from the Continuum plug-in suite. First, create a new project in After Effects, selecting the aspect ratio, width, height, and frame rate you want. Then, select the Layer menu and click on New > Solid. Place the solid layer on top of the composition, and apply the BCC UpRez filter to the selected layer. Open the Effects Control panel and select the video from the Source Layer drop-down menu. The video will then be upscaled to the size of the solid layer resolution.
Finally, press Enter to finalise your layer trim, and the crop will take effect.

Using the Shape tool
To pan-crop in After Effects using the Shape Tool, follow these steps:
First, select the layer you want to crop. You can do this by opening a video and choosing the necessary layer from the available options on the left of the timeline.
Next, switch to the Shape Tool in the toolbar. The Shape Tool is used for rectangular or shape masking. You can also use the Pen Tool for irregular shapes. The Shape Tool is usually located in the top-left corner of the toolbar, and you can use the hotkey 'Q' to activate it.
Now, draw your crop shape. If you want a rectangular shape, click and drag to the required dimensions. You can also create a custom shape by hand.
After you've drawn your shape, move your Shape layer underneath all the other layers you want to crop in the Layers Panel next to the Scene Timeline.
Finally, long-press your Shape layer and select 'Use as Mask'. You can now animate your video crop or continue animating your scene inside the mask area.
It's important to note that the Shape Tool creates a mask when used on a selected layer and a shape layer when used on a non-selected layer. You can also adjust your mask by selecting it in the timeline panel and then adjusting the points on the mask in the composition panel.
