A while back, I wanted to upload the same video on multiple social platforms like Instagram, TikTok, and Facebook. This made me realize that all these platforms have different aspect ratios and I have to resize my video before uploading it. Thankfully, with the right tools, I could easily resize a video online and so can you. Here, I will let you know how to adjust or resize your videos using different online tools like a pro.

Part 1: Why you Might Want to Resize your Video Clips?

Before learning various techniques to resize a video online, let’s uncover why so many people would like to do the same:

Downsizing: Chances are that you might wish to share the video with others and could be finding it hard to do it due to its heavy size. In this case, you can just reduce its size by changing its frame rate or aspect ratio.

Optimization: You might also wish to resize the video before posting it on social platforms like YouTube, Facebook, Instagram, and more, as they have different video requirements.

Other Reasons: There could be several other reasons for optimizing a video, like resizing it before emailing it to someone, for video editing, and so on.

Part 2: What Kinds of Adjustments you can make on your Videos?

Video editing is a broad concept, and you might wish to implement the following effects on your videos while working on them:

Frame Adjustment: Changing the central frame of the video according to your needs or altering its frame rate to optimize its size.

Zoom in/out: In this, you zoom in to a particular object or zoom out of a frame while transitioning.

Panning: Video panning is a popular transitioning technique in which the frame moves horizontally in right/left directions.

Cropping: Just like images, we can also crop the overall screen/canvas of the video in a preferred ratio.

Trimming: In trimming, we alter the length of the video by taking out any unwanted segments.

Speed Adjustment: This is a useful technique in which we alter the playback speed of the video (fast forward or slow motion).


Part 3: How to Resize Your Videos Effectively with DemoCreator?

One of the best ways to resize a video is by taking the assistance of a reliable tool like Wondershare DemoCreator. The all-in-one application can help you record the screen of your system and edit your videos with tons of readily available features. Therefore, you can easily use the application to implement tons of editing effects and make your videos ready for different social platforms.

Method 1: Adjusting the Frame Rate and Video Size while Recording

If you don’t want to spend time editing, then you can simply take some preventive measures while recording the video instead. To do this, you first need to know the overall dimensions and aspect ratios of various social media platforms.

Great! Now when you know the preferred aspect ratios and dimensions for various platforms, you can easily take the assistance of DemoCreator. To record your screen, just launch Wondershare DemoCreator, and select a recording mode from its home screen.


Afterward, you can simply set up the audio input (like the microphone or system’s sound) and the webcam input as well. Here, you can go to the customization settings to manually set up an area for recording on the screen. You can also select a frame rate for video recording on DemoCreator.

Afterward, you just click on the red icon to start recording your screen at the selected frame rate and aspect ratio.

Method 2: Use the DemoCreator Video Editor to Resize and Adjust your Video

As I have listed above, Wondershare DemoCreator also offers an inbuilt video editing tool that you can access from its home. Once the video editor’s interface is opened, you can just load your video on it and drag-and-drop it to the timeline at the bottom panel.

Afterward, you can use the inbuilt features of DemoCreator to make all kinds of edits and apply numerous effects to the video.

  • Zoom in or out of the Video

After loading the video, you can go to the “Effects” section from the sidebar, find the “Pan & Zoom” feature, and drop it to the video at the timeline. You can now select the effect to find the zoom-in and zoom-out features from the bottom panel. There are also provisions to adjust the aspect ratio of the video here or alter its focal area. zoom-in-out

  • Pan or Swap the Screen

In the same Pan & Zoom window of DemoCreator, you can also find three more options at the bottom. Using them, you can apply the pan left or pan right effects to move the screen in any desired direction. There is also a Swap effect that you can apply to swap the starting and the ending parts of the video.


  • Crop your Video

Using the DemoCreator editor tool, you can also crop the screen of your video. Once the video is added to the timeline, you can click on the crop icon from its toolbar. This will open a new window, letting you manually select the area on your window that you wish to crop.


  • Trim your Video

In video editing, a lot of times we wish to get rid of any unwanted segment from the clip. To do that, you can just drop the video on the timeline at the bottom and move the cursor to the end of the clip (its icon would change to purple). You can now drag the cursor backward or forward to trim the clip and can also click on the marker icon on the toolbar to add markers in between.


  • Adjust the Video Speed

There are also several other editing options that you can access on DemoCreator. Once you select the clip, you will get options to change its playback speed, opacity, composition, and more on the side. You can just use the slider options to set up a preferred value for its playback and other parameters.
