YouTube Upload: Supported Video Formats, Size, Resolution

This page provides the answers of the best YouTube upload video formats, namely, the most suitable file extensions, resolution, file size and video formats supported by YouTube, the most famous online video sharing website.

YouTube have updated its supported formats list to accept HEVC/H.265 files. HEVC can reduce the decoding overhead for easier end user playback, and also can reduce the amount of bandwidth and network traffic. Therefore it is the best encoding method and file format recommended for YouTube uploading, especially when your video file is large in file size or high in resolution (such as 4K).

Part 1: What Video Formats Does YouTube Support for Uploading?

What are YouTube friendly video types? The formats of videos downloaded from YouTube are MP4, flv, WebM, etc. Then what video formats are supported and accepted by YouTube for uploading and editing?

YouTube accepted video formats:

  • 3GP (.3gp, .3g2, .3gpp)
  • MPEG-4 (.mp4)
  • AVI (.avi)
  • MOV (.mov)
  • FLV (.flv)
  • MPEGPS (.mpg)
  • WebM (.webm)
  • WMV (.wmv)

YouTube supported video codecs:

CineForm (GoPro), DNxHR (UHDTV), HEVC, H264, ProRes (Apple)

Supplementary: the YouTube recommended video profile for your video codec is High Profile and the chroma subsampling is 4:2:0. Certainly, if high quality is your ultimate goal and uploading speed is the next best thing, chroma subsampling 4:2:2 or 4:4:4 is accepted by YouTube, too.

From what have been listed above, we may roughly draw the conclusion that YouTube embraces a wide range of video file formats. However, there are many other factors we have to take into consideration, say, file size, video quality loss and compatibility with players.

To sum up, MP4 overlaps all the advantages with small file size, high compression rate (for high quality) and popularity. MP4 includes two video codecs, namely, MPEG4 and H.264, which are both widely supported, together with AAC (2 Channel - 8 Channel) and MP3 as audio Codec. So it is the most recommended YouTube upload video format.

Part 2: What are the Best YouTube Upload Settings?

Besides video formats, YouTube also has very strict requirements for music, video and movie uploading, in terms of file size, duration, resolution, codec, frame rate and bitrate.

  • File size: Video file size is limited to 2GB for YouTube uploading. But size larger than 20GB is allowed by using an up-to-date browser. And the maximum is 128GB. Check here to get more detailed info about YouTube video size limit.
  • Resolution: 4:3 (640 x 480) or 16:9 (1280 x 720). When the video is uploaded to the site, YouTube will make it 16:9 or add vertical black bars (for 4:3). So, don't add horizontal black bars before uploading a video. Check the way to change aspect ratio from 4:3 to 16:9.
  • Duration: YouTube once limited the length of a video file to 15 minutes. But now user can upload a video longer than 15 minutes.
  • Frame rate: Keeping original video frame rate is preferred. And 25-30 fps is recommended.
  • Bitrate: Bitrate is different from screen resolution and is highly related to video codec. Actually, it is less important than other factors to consider before YouTube uploading. YouTube experimented with Dynamic Adaptive Streaming over HTTP (MPEG-DASH), which is an adaptive bit-rate HTTP-based streaming solution optimizing the bitrate and quality for the available network.
  • Deinterlacing: Although videos either in progressive scanning or interlaced scanning mode can be uploaded, YouTube suggests turning interlaced videos to deinterlaced before uploading for the best video quality. Therefore, progressive scanning is needed for video uploading.

There are true examples in downloading YouTube videos:

  • MP4 720p: 4.0 Mbit/s (variable bitrate with peaks of 5.0 Mbps)
  • MP4 1080p: 8.0 Mbit/s (variable bitrate with peaks of 10.0 Mbps)
  • FLV HQ: 1.5 Mbit/s (variable bitrate with peaks of 3.0 Mbps)

What if you upload a video that doesn't comply with regulations to YouTube? Usually, your video will be auto compressed to YouTube accepted specifications. For example, you record a 8K video with Samsung Galaxy S21 and upload it to YouTube, you probably get your video in 1080p. Of course, it doesn't exclude that your network is poor enough, taking forever to process your source 8K video.
