Suggested upload file specs

You can upload clips in the container formats .mxf, .mov, .m4v or mp4 with common codecs like H.264, ProRes etc. which are then converted by Webgate.io to optimized streaming formats.

To make start timecodes available in the Webgate.io.io player and the downloadable proxy/streaming files, the uploaded videos must contain a start timecode, for example, through XMP metadata.

The audio channel assignment of the uploaded video file should ideally be an interleaved stereo file. You can also upload videos with multi-channel audio to Webgate.io.io. In this case Webgate.io.io will perform a generic downmix. In the case of 5.1 interleaved audio, Webgate.io.io expects the audio channel assignment: L, C, R, LS, RS, LFE. If you upload a video with 5.1 multi-mono tracks to Webgate.io.io, the assignment L, R, C, LFE, LS, RS is expected.

If you add a video with 16 multi-mono tracks, Webgate.io uses channel 1 for left and channel 2 for right.

If you upload a video containing two audio streams with one channel each, Webgate.io performs a mono mixdown under the following conditions:

• The Channel Layout is set to «C».
• The Channel Layout is set to «M» and ChannelPositions is set to «Front: C».

In both cases, the audio level is reduced by 3 dB.

Channel Layout and ChannelPositions can be verified using MediaInfo. MediaInfo is available within Webgate.io in the metadata view of playlists.
