Vimeo videos are viewable in a variety of different qualities, ranging from 360p to 4K. In “Auto” mode, our player switches between all available qualities to accommodate changes in the viewer’s Internet speed. The following table shows the minimum speeds required for each playback quality:
|Quality||Required Minimum Bandwidth|
When a video plays in lower than expected quality, it’s likely because the viewer’s Internet speed (bandwidth) cannot support higher quality playback.
Viewers can manually select a particular quality in the player’s HD quality menu. (This may result in frequent buffering if the bandwidth does not meet the required minimum outlined above.) Only qualities up to the source file’s native resolution will be available.
Quality problems can also arise when there is a problem with the source video file. If the quality issue is visible in the source, try re-exporting the file and re-uploading to Vimeo.
Frequent buffering during playback
Frequent buffering can occur when the viewer’s Internet bandwidth does not support playback of the selected video quality.
Try the following to reduce buffering during playback:
- Switch to “Auto” in the quality menu, if available
- If “Auto” is not available, switch to one of the lower quality options
- Close extra browser tabs or other applications that may be using extra bandwidth
- If possible, disable VPN connections that may mask your computer’s true geographic location
360 video playback
360 video requires more computer processing power than regular video, so you may need switch to one of the lower quality options for smooth playback on your system. We recommend setting the player to “auto” in the quality menu and viewing from a supported environment.
Player debug panel
The debug panel helps provide critical information related to your playback experience. This includes the CDN, your bandwidth to that CDN, the rate of dropped frames, embed size, and more.
To log your playback experience using our debug tool, please follow these instructions:
- Open any video you’ve noticed this issue on.
- Press “D” on your keyboard to open a debug panel in the player.
- Press play and watch the video for a full minute (or as long as possible). Important: Do not let the video end before moving on to step #4 (otherwise, the debug panel will disappear!)
- Click the blue "Open link" button.
- Copy the link below the words “Share your results by copying this URL.”
- Paste the results from the debug panel in an email to email@example.com with the subject line, Playback debug results.
In addition to the debug panel log, it also helps to send us a complete list of the specific videos you’re attempting to view, a detailed description of the problem you’re experiencing, and your browser and operating system specs.
