What is the best YouTube video format?

MP4 is the best video format for YouTube with AAC-LC audio codec and H.264 video codec, and a standard aspect ratio of 16:9. This produces a high-quality video at a smaller file size. YouTube also recommends uploading videos in a format as close as possible to the original, especially if it’s HD or a higher resolution

While MP4 is the recommended file format, here’s a look at other video formats compatible with YouTube. Note that these are basically a mix of codecs and/ or containers that make up a video file.

What is the best YouTube video size?

The following video resolutions and dimensions are recommended to ensure the best quality YouTube video uploads.





426 x 240

This is the minimum YouTube video size (good for viewing on a slow internet connection).


640 x 360

This is best for YouTube videos that need to be embedded on websites.


854 x 480

This is the standard definition of YouTube video size.


1280 x 720

This is the preferred YouTube HD video size when viewing videos on mobile data or a slow internet connection.


1920 x 1080

This is the standard HD video size and the best option for viewing.


2560 x 1440

This is 2K video quality YouTube video size.


3840 x 2160

This is 4K video quality YouTube video size.

If your video is not in the recommended 16:9 aspect ratio, YouTube may add padding for optimal viewing (see image below).

Other important factors to keep in mind while uploading a YouTube video:

- The maximum YouTube video file size is 128GB.
- The maximum YouTube video length is 12 hours. 

Your best bet? Upload your video using the largest dimensions possible within the format you’ve chosen.

Why do you need to pay attention to your YouTube video format?

- Each file format is processed differently by YouTube and this might affect the playback of your video. Your video might not display properly, and the viewing quality may suffer.
- Certain YouTube video upload formats are such that they process a single video and produce a larger file size. This affects your video quality when shared on other social media portals.
- Keeping these points in mind, as YouTube is all about the video viewing experience, it’s essential to select the most advantageous YouTube video upload format.

YouTube’s recommended video upload settings

Whenever you upload videos to YouTube, you have the option to select your video encoding settings. Let’s understand what this means. Historically, for a video recorded at 30 frames per second (fps or frame rate), you had 30 photos per second of footage. That’s 1,800 images per minute of video. As a result, video file sizes were massive. Uploading these digitally would take a long time and require a whole lot of space on servers. 

The only sensible solution was to compress these videos, but the quality was lost through this process. Engineers then developed video encoding which provided a way to compress these files without compromising the quality. Video encoding is basically the digital method used to compress files so that they are not saved as individual images but as fluid videos. Video encoding happens automatically when we are recording videos or during the editing process, using tools called codecs and containers.

When your video is ready to be uploaded to YouTube, the video file type or format also refers to the container and codec that has been used to encode it. Let’s look at the difference between video file containers and codecs:

Video file containers: Video file containers refers to how the video, audio, and metadata content are organised. They can also be called a file extension, the most popular ones being .MP4 and .MOV. MP4 h.264 is the current industry standard for high-definition video and provides the most practical way of distributing video content. 

YouTube video format encoding

Video file codecs: YouTube also uses file codecs or code to compress and then decompress video files. In fact, certain poor-quality codecs can result in low-quality compression and decompression. This means that though they can create small video file sizes, the video quality might also be affected. 

In order to get the best results, YouTube recommends the following upload encoding settings for all videos:

Container: MP4
Audio codec: AAC-LC
Video codec: H.264
Frame rate: Content should be encoded and uploaded in the same frame rate it was recorded. Common frame rates include 24, 25, 30, 48, 50, 60 frames per second (other frame rates are also acceptable).

Quick Tips

Tip #1 - Since your videos are encoded while filming, shooting your YouTube videos using 1080p resolution is optimal. This offers the maximum resolution for a full HD video and keeps your file sizes smaller than when filming in the larger 4K and 2K video qualities. 

Tip #2 - 720p is the minimum resolution needed for an HD video. You will thus be able to reduce the file size while still retaining a sharp video quality.

Tip #3 - Note that if you are using your mobile phone to record video, it will automatically be saved as MP4. 

Tip #4 - Encoding your YouTube videos means faster upload speed and less usage of WiFi or mobile data as well as device storage space.

Tip #5 - You can also ensure your video is encoded for YouTube when editing it.

Q.6 Why do some of my YouTube videos look blurred or fuzzy?

Ans: Videos may often appear blurry on YouTube immediately after they are uploaded. This is because YouTube displays a low-resolution version of your video while they're still processing the HD version in the background. But your video will ultimately appear in HD once it's ready.

Q.7 Is MPEG the same as MP4?

Ans: MPEG-4 is a video codec recognised by MPEG (Motion Picture Experts Group) as a standard of audio and video data compression. Over the years, it has branched out into many different parts, among which are MPEG-4 Part 2, MPEG-4 part 10 and MPEG-4 Part 14, and more. Despite this, in a way, the MP4 container format stands for MPEG4. However, it only applies to MPEG4 Part 14 (MP4). It's called MP4 mainly because  MPEG-4 Part 14 has .mp4 as its filename extension. This clearly shows that MPEG4 is not the same as MP4.
