To increase video size in After Effects, you can adjust the composition settings to a larger resolution. Here's how:
-
Go to Composition Settings: Navigate to
Composition > Composition Settingsin the After Effects menu. -
Adjust Width and Height: In the Composition Settings window, you'll find options for
WidthandHeight. Enter your desired dimensions for the new, larger size. For example, to create a 4K video, you would enter3840for the width and2160for the height. -
Consider Scaling (if needed): If your existing footage is smaller than the new composition size, you may need to scale it up. In the timeline, select your layers and use the Scale property (press
Sto reveal it) to increase their size. Be aware that scaling up too much can lead to a loss of quality, so it's best to work with high-resolution source footage when possible.
Here's a simplified representation in a table:
| Step | Action | Details |
|---|---|---|
| 1. Access Settings | Go to Composition > Composition Settings |
Opens the settings panel for your current composition. |
| 2. Set New Dimensions | Change Width and Height values |
Input the desired width and height in pixels (e.g., 1920x1080 for HD, 3840x2160 for 4K). |
| 3. Scale Existing Layers | Adjust the Scale property on each layer |
If your footage is smaller than the new composition size, increase the scale of your layers as needed. |
Important Considerations:
- Aspect Ratio: Be mindful of the aspect ratio when changing dimensions. If you stretch the video disproportionately, it will appear distorted.
- Source Footage Quality: Scaling up low-resolution footage will not magically make it high quality. The result will be a larger, blurry video. Always start with the highest quality source footage available.
- Project Panel: You can also change composition settings directly from the project panel. Simply select the composition and go to
Composition > Composition Settings.
By following these steps, you can effectively increase the video size in After Effects to your desired dimensions.
