There are many reasons why your video may look different once uploaded to Vimeo. Here are some common causes:
Decoding technology
The most common culprit for color variation is your browser’s decoding technology.
You can determine whether this is the cause by testing your video in different browsers. If the color of your video looks accurate in Safari, but not Firefox, you may be encountering a decoding variation. Unfortunately, Vimeo does not have any control over the decoding of your video.
Missing color properties
Another potential cause for color variation in your video is when one or more of the color properties are missing.
Color properties–color space, color range, color primaries, transfer characteristics, and matrix coefficients–are controlled by your editing software.
If missing color properties are causing your video’s color variation, we’ll display a message in the video files section of the settings page suggesting that you try re-encoding your video with explicit color properties.
Hardware or software issues
The viewer's hardware (monitor, graphics card, etc.) and software play a big role in the viewer's playback experience. Try testing your video on different setups and take note of the differences in color (if any).
Conversion process
In rare cases, our conversion process will lead to variation between your source file and our playback versions.
To test whether this is the case, follow these steps:
- Go to your video page.
- Use the Download button to download both your source file and the largest HD Vimeo version of your video.
- Compare the two versions of the video by playing them in the same program on your computer (e.g., Quicktime, Windows Media Player, or VLC).
- If you see any differences in color when comparing the videos, please contact us and provide the following information:
- A link to the video(s) in question.
- A description of the places in the video where the color is especially off
- Side-by-side screenshots that show the discrepancy between the two videos
