Step 3. Choose the output format

Open the Video tab to see the list of video formats, including MP4, AVI, WMV, and many others. To convert your video to a specific format, hit the name of the desired format. You’ll see a list of presets with different resolution options. If you want to keep the original resolution and aspect ratio, select the option with Original Size in its name. Want to change the aspect ratio of your video? For your convenience, we matched the most popular presets with corresponding aspect ratio values.

  • 3:2: 480 × 320; 720 × 480
  • 4:3: 240 × 180; 320 × 240; 640 × 480; 384 × 288
  • 16:9: 640 × 360; 960 × 540; 1280 × 720; 1920 × 1080
  • 16:10: 1280 × 800

Also, Movavi Video Converter includes dozens of ready-made presets for various devices, including iPod, iPhone, iPad, PSP, Xbox One, and many others. Just click Devices and find your device in the list. If you choose a ready-made preset, you don’t have to specify any additional options, because your video will be converted with the optimal settings for playing on the selected device. In this case, you can skip the next step and jump to Step 5.

Step 4. Specify video settings (Optional)

If you want to set the width and height for your video manually, click the Cogwheel button next to the Output format field. In the format settings window that appears, choose the appropriate video and audio codecs and specify various video parameters.

As Movavi Video Converter uses square pixels only during the conversion (except when converting to DVD), the aspect ratio of an output video is always set automatically according to its width and height proportions. So, open the Frame size list and select the right resolution option or pick Custom and enter the required width and height values into the corresponding fields. And don't forget to select the appropriate resize method!

After all the parameters have been set, hit OK, and you’ll be returned to the main program window, where you can finish transforming your video.

A note on saving video in a DVD-compatible format (VOB): all VOB files made in Movavi Video Converter contain non-square pixels so, after choosing the appropriate size preset, you can select the required aspect ratio – 16:9 (widescreen) or 4:3 (full screen) – in the format settings dialog.

Click the Convert button to initiate the conversion process. The folder with the finished files will open automatically upon completion, unless you disabled the feature in the program settings.

What is an aspect ratio?

The aspect ratio of videos and pictures is the ratio of the measure of pixels from width to height. This ratio relates directly to the display on which a video is being played as well as the shooting ratio of the camera – you can shoot something in 16:9 and display it in 4:3 if you want.

The aspect ratio doesn’t represent the actual pixel size in terms of height and width. So 16:9 doesn’t have a pixel size of 16 × 9 – that would be very small.

A more common pixel size is 1920 × 720px – high definition resolution – which has a 16:9 aspect ratio.

Why are aspect ratios important for video editing and social media?

Often when trying to post on social media, people have difficulty finding the right size for their videos. No matter how much they edit and resize the video, it appears to stretch and is obviously not acceptable for posting.

The problem lies in trying to directly adjust the dimensions of the pixel size to fit into the platform when the editor should instead focus on the aspect ratio.

Ultimately, the platform is going to crop your video into the shape of the aspect ratio no matter what, so it’s important to understand what ratio you need to use for what platform and in what situation.

You may need to use a video aspect ratio converter or resizer software in order to get the right fit. Just remember it’s not a good idea to make a video widescreen if it wasn’t shot in the proper format.

The list below identifies the available aspects and pixel sizes for the most common social media platforms. It will help you choose between different ratios to post a video without stretching.

  • Instagram

Feed posts. To start, Instagram feed posts support video aspect ratios in 16:9, 4:5, and 1:1 with varying pixel sizes.

But just because a platform allows you to post in different sizes, it doesn’t mean you should increase and decrease without discernment. No matter what, the platform will automatically adjust the size to fit those ratios.

Instagram is an app geared toward mobile use as opposed to a desktop computer or a TV and feed posts will not flip horizontally. Because of this, it’s best to post videos in a 4:5 ratio at 1080 × 1350 for optimal viewing, or at least go with a 1:1 square ratio at 1080 × 1080.

Stories, Reels, and Instagram live. There’s less flexibility when it comes to stories, They all play in a vertical video format of 9:16 and while you can adjust your stories down to 1080 × 608 and there are hacks to make them horizontal, uploading at 1080 × 1920 is best for optimal viewing without borders.

Reels and Instagram live are both locked at the 9:16 ratio and at 1080 × 1920.

IGTV. Things get a little more complex when trying to figure out what ratio to use for Instagram’s video app that allows for longer videos outside of the feed. It’s again optimal to opt for the 9:16 ratio and at 1080 × 1920 for mobile viewing.

However, if your video was originally shot for another platform like YouTube geared for 16:9 at 1920 × 1080, you can still post the video in this format via IGTV. It’s the one place on Instagram where a viewer can flip the clip horizontally, but you may want to put a message indicating that viewers rotate the video.

With IGTV you also need to be aware of the preview – the first 15 seconds – that plays in a viewer’s feed at 1080 × 1350. Fortunately, Instagram allows you to align the video, so you can show exactly what you want.

You can also upload an image instead for the preview, and if you choose this option, opt for the 1080 × 1350 resolution.

Last, the preview in your profile grid will show at 1:1 and at 1080 × 1080. For this preview, you can either take a snapshot from the video or upload it from your camera roll.

Carousel. Like videos in your feed, carousel posts offer portrait (1080 × 1350), landscape (1080 × 608), or square (1080 × 1080) viewing. But once you select a ratio and size for the first video, all other videos will crop and adjust to the same ratio and size and maintain that ratio for the rest of the sequence.

Instagram recommends a 1:1 ratio for all carousel videos.

  • YouTube

All YouTube videos play in a 16:9 ratio, but you have the option of adjusting the resolution from the YouTube minimum all the way up to 4K. Here’s a breakdown of the default resolutions with their pixel sizes:

  • 4K UHD – 3840 × 2160

  • 2K QHD – 2560 × 1440

  • Full HD – 1920 × 1080

  • HD – 1280 × 720

  • SD – 854 × 480

  • Normal website – 640 × 360

  • YouTube minimum – 426 × 240

Those are the ratios that YouTube will play, but you have the option to upload videos in any aspect ratio you want as long as you stay within the minimum or maximum resolution.

Some popular ratios include 1:1, 4:3, and 9:16. In this case, YouTube will put black or white bars to fill in space based on the viewer’s settings instead of cropping or stretching the video.

For example, you may want to convert from 16:9 to 4:3 for a video to give it an older feel. YouTube will still play the video in a 16:9 display, but it will add black or white bars to the sides of the video.

  • Facebook

Videos on Facebook are available in ratios ranging from 16:9 to 9:16, but they must be a resolution of 1920 × 1080 or less. Facebook also accepts videos in any format, but they recommend uploading them in the MP4 format.

Also, for Facebook videos, it's important to consider your audience. If you have more of a mobile following, you may want to opt for a 1:1 or 4:5 ratio, especially if you’re paying for an advertisem*nt. This will allow viewers to see the video on desktop or mobile platforms.

  • Twitter

Twitter offers a very wide range of available ratios and pixel sizes. You can upload videos in any aspect ratio you want. However, the platform only supports a pixel size up to 1920 × 1200 or 1200 × 1920 based on whether the video is horizontal or vertical. The minimum pixel size for Twitter is 32 × 32.

  • Vimeo

Vimeo offers the widest range of options for uploading videos. As long as you’re willing to pay for the online storage, you have the ability to upload videos in literally any aspect ratio and in pixel sizes up to 8k UHD at 8192 × 4320 with no minimum.

Summary

With this guide, you now have a better understanding of aspect ratios and how to use them to effectively present your videos on different platforms. Remember to always research the display ratio and pixel size requirements anytime you want to upload. Changing the ratio is an easy process with Movavi Video Converter.
