How to Resize Video without Losing Quality [No Watermark]

Videos are getting crisper yet larger with the popularity of 4K cameras like GoPro, DJI, DSLR, etc. Unfortunately, file sizes and dimensions vary and don't match your social platform. For instance, you created a landscape footage with GoPro Hero 9, which you want to share it on your Instagram Story. Or you just want to have your vertical video played on YouTube without black bars on both sides. This makes it a must to resize video. Without devoting time and energy to find the right tool, we are here sharing the best video resizers to cater to your needs.

Part 1. 4 Essential Elements to Consider in Video Resizing

Technically, a video file can be created in various dimensions, orientations, aspect ratios and file sizes. They are unique elements of a video, but are often used interchangeably. Understanding how one affects the other can help you resize the video in a proper proportion, and makes sharing no longer a hiccup. Let’s dive through them in detail.

1. Video Dimension

Each video has a fixed width and height, measured in pixels & collectively known as the video dimension. This is the primary factor to consider when resizing a video. Generally, 1920x1080p is known to be the standard video size across HDTVs. You shall change the dimension to 1080x1350p to match Instagram Feed, for example.

2. Aspect Ratio

Aspect ratio refers to the ratio of width to height, incl. 16:9, 9:16, 4:3, 1:1, 4:5, etc. For example, a 4K video with a dimension of 3840x2160p has an aspect ratio of 16:9. E.g. it's a must to resize the video to 9:16 framed for Instagram/Facebook Stories, Ticktok, YouTube shorts.

3. Orientation

Video orientation can be categorized in landscape, portrait, and square. For instance, a square video is framed with 1080x1080p size & 1:1 aspect ratio. You shall follow the recommended dimension for the directions. If it's going on Snapchat Ad or Tiktok post, make it vertical.

4. File size

In a broad sense, resizing video not only involves in changing the video dimension and aspect ratio, but also means reduction of video file size, which is often confused with dimensions. Technically, file size is communicated in GB, MB, or KB, primarily determined by bitrate, together with resolution, frame rate, and encoding standard.

Part 6. FAQ about Video Resizing

1. How Can I Resize a Video without Cutting It?

Most often, when you upload a video with an aspect ratio which doesn’t match that of the social media, the video will be cut off. To preserve the content in a consistent way, one option is to pad all your videos. For example, you can try WinX Video Converter, with which you can expand to the profile video resolution flexibly.

Also make sure the video is within the limits of the maximum file size and length of your social platform. For example, when you upload a video longer than 15 seconds to your Stories, Instagram will automatically cut it into 15 second segments.

2. How Do I Resize an MP4 Video?

There are such tools as Handbrake available to change the size of MP4 video. You can type in video width and set video height. However, Handbrake crop the black bars in the MP4 or any other video automatically as a move to save the encoding time and disc space. Users have to manually adjust the settings to disable it. So if you are unsatisfied with the feature, you can choose other tools like VLC or WinX Video Converter for help.

3. How Can I Resize a Large Video File?

Both online tool and desktop software can resize a video file. But most often the former imposes restriction on the input file size. For example, Clideo allows to upload a video within 500mb in size. In addition, processing the large video file, such as 4K file, is computer-intensive. Consequently, the video resizing will be lengthy, especially when you are equipped with aging hardware.

In this situation, it’s better to resort to a desktop video resizer software for help. WinX Video Converter is highly recommended since it takes advantages of hardware acceleration to decode, process and encode large video.

4. How to Resize video Online with No Watermark?

Online video resizers typically embed watermark to the exported video file. They ask for subscription further to remove watermark. In the meantime, the trial version of most desktop software lets you crop the video, but only when you get the licensed version can you resize video without watermark.

5. How Do I Resize a Video on Windows 10?

You can take advantages of the Micorsoft Photos App (originally Movie Maker) included in Windows 10 to do the task. By clicking the crop icon, you can remove the black bars. It also allows you to change the aspect ratio between 9:16 and 3:4, or reset the video vertically or horizontally.
