This guide will show you how to resize videos using DaVinci Resolve and Filmora Wondershare. Once you learn, it becomes as easy as a click. Let's dive in!

Davinci Resolve is a very powerful tool to edit videos. Let’s suppose, you have some videos shots and all the videos have different sizes, some of the videos fit in the timeline and some are out of the timeline. No matter, you are going to make a video on the same scale with the same size.
Resize the video can be done in three ways:
- Zoom in zoom out
- Cropping
- Retime and scaling
Method 1. Zoom in and Zoom out
First of all, select the videos in your timeline. You should stay in the middle of the frame to set it because it’s too wide. The timeline moves forward and backward. Let your video be 4k, go to the bottom-right corner and click on timeline format. Select timeline resolution, select ultra HD, or whatever you want from the drop-down list.
Go to the inspector from the up-right corner and select Transform under the video section. Here you can resize your image. Place the mouse over zoomx (Horizontal) and zoomy (vertical) values to drag left or right for zoom in or zoom out. The video can be resized accordingly.
Here you can also change its rotation.
Method 2. Cropping
Go to the inspector from the up-right corner and select Transform. Now choose Cropping. Here are four options Crop left, crop right, crop Bottom, and crop Top. You can drag the scale from left to right to adjust the crop settings according to the desired result.
Method 3. Retime and scaling
Go to the inspector from the up-right corner and select retime and scaling. You can choose stretch, Fit, Fill, or crop for cropping the video from the drop-down list.
- The Crop function is used to remove the unnecessary or uneven part of the video.
- The Fit function is to have the video auto-center and the selected clips are formatted according to the screen dimensions.
- Stretch Function allows changing the length of the certain clip at a certain duration.
After transforming, cropping, and resizing the videos, you can copy the same settings without repeating the above steps for each video.

For example, if your video was originally widescreen (16:9), switching to a square (1:1) or vertical (9:16) aspect ratio can reduce the file size.
