Upload Specifications
All files should have a container (e.g., name your file “video.mp4” and not “video”) and must be a supported type from the list below.
Audio files can contain multiple audio tracks, but MediaSilo can only support 1 channel per track.
Best Quality Recommendations & Considerations
We recommend you upload files no larger than 30GB. Note that MediaSilo will automatically create proxies of the files you upload to ensure the best possible viewing experience across different browsers and devices. To learn more, please see Uploading Web-Playable Files.
If the file you upload to MediaSilo meets certain specifications, the file will play in MediaSilo as is, without transcoding. In this case, it’s important to be mindful of different Internet speeds: depending on the strength of your Internet connection, a larger file (over 2K resolution) could result in buffering issues.
SDR (Standard Dynamic Range) content is recommended. If you have HDR (High Dynamic Range) content, it's recommended that an SDR graded version be uploaded.
Limit the number of transcodes. You may opt to upload a mezzanine, a re-export from your finishing software, or a less compressed file (ProRes, DNxHR, etc.) instead of an h.264 to retain as much visual quality as possible. Note: transcoding from an h.264 to ProRes or DNxHR file prior to uploading to MediaSilo negates this.
Supported File Types
MediaSilo supports a wide range of different file types, including many of the most common video, audio, image and document formats, as well as archive files.
MediaSilo does not support project files (e.g. .aep, .prproj), nor does it support raw formats (e.g. .r3d). The below are supported for preview:
