ARTS-4334: Video Compression Guidelines for Vimeo Uploading

Posted by: Ping
CodecsA codec is the format in which your video is encoded. We accept most major codecs, but for best results we recommend H.264 or Apple ProRes 422.H.264

H.264 is a standard codec that balances high visual quality with efficient file size. It’s a great starting point for encoding your videos as it ensures you’ll get the most of our your upload quota while minimizing upload and conversion times. Be sure to choose the “High Profile” H.264 setting instead of “Main Profile.”

Advanced H.264 settings: To make your uploads extra smooth, choose the following advanced settings whenever possible.

  • Closed GOP
  • CABAC (to reduce your file size)

Here are some codecs that will not work on Vimeo: G2M2, G2M3, Canopus HQ.

Frame rate: 24, 25, or 30 FPS (Constant)

When preparing your video for upload, it’s best to maintain the video’s native frame rate when compressing your video. If your footage exceeds 60 FPS, we will automatically reduce the frame rate. Important: We recommend a constant frame rate throughout your entire video. Always choose “constant” frame rate instead of “variable” frame rate.

While we accept many frame rates, these are the most commonly used:

Bit rate

Bit rate (also known as data rate) controls the visual quality of the video and its file size. If your video editing software gives you the option, choose a “variable” bit rate and select a value from the ranges below. You can experiment with different rates if your file is too large or you’re not happy with the quality of your source file.

Quality Bitrate (Mbps)
SD 2 – 5
720p 5 – 10
1080p 10 – 20
2K 20 – 30
4K 30 – 60

Videos come in all shapes and sizes but these are some of the most common formats.

Channels: Stereo
For best results, we recommend 2-channel Stereo audio. For any number of channels above 2, we will downmix your audio to 2 channels.

Codec: AAC-LC (Advanced Audio Codec)

For best results, we recommend using AAC-LC (low complexity) for the audio codec.

Data rate: 320 kbit/s
  • For best results, encode your audio at constant rate of 320 kbit/s.
Sample rate: 48 kHz

For best results, set your audio sample rate to 48 kHz. If your working setting is already less than or equal to 48 kHz, leave it as is. For any audio uploaded with a sampling rate over 48kHz, we will resample your audio to 48 kHz or below.
