Second section of the back office, it is in this section that you will be able to upload your different media and manage them afterwards. In particular, you will find Video files, Live streams, Audio files, Other files, Bonus files and Subtitles. This section is a real "virtual library" of your platform.
=> This is where your videos will be transcoded and hosted, in the Video Files section.
As a reminder, Transcoding = conversion of video files into different profiles with an HLS or dash streaming protocol.
Why do my video files need to be transcoded?
A source video file is transcoded into as many resolutions as the user can choose (video profiles). This makes it possible to offer adaptive streaming: the video will automatically switch from one profile to another for maximum playback fluidity (first low resolution, then better and better, which is why during the first seconds of streaming, image may pixelate).
Step 1: Before uploading your videos, you must first configure your streaming profile (encoding presets).
Important: when opening your back-office, 3 profiles (encoding presets) are already activated by default, 2 HD + 1 SD. These 3 encoding profiles/presets are used by the vast majority of our customers.
=> it is therefore very likely that you will not have to configure anything for this first step, except for specific needs.
A profile = resolution + bitrate (amount of information transmitted per second of video).
To consult the profiles and modify them (add / delete):
> Media management / Media sources:
Click on “Kinow Video” if your videos are hosted by Kinow (you can integrate other video sources if this option is included in your subscribed offer).
You access the list of encoding presets.
The 3 pre-selected levels prevent to over-consume bandwidth and to avoid potential viewing / buffering problems.
As a reminder: 1 hour of transcoding credit = 1 hour of film encoded in the 3 profiles preselected by default.
If you doubt the connection of your users, you can also activate the penultimate profile of the list.
=> Important: Once a film has been uploaded/transcoded into several profiles, you cannot add or delete a profile. You must delete the uploaded video file, and start the operation again.
Be careful when defining your encoding Presets.
It is also in this sub-section > Media sources that you can configure the video content protection system (DRM):
By default, ClearKey DRM is applied to your videos when transcoding.
There is another "Hollywood DRM" system for content requiring higher protection or having to meet the conditions of certain studios / rights holders.
2nd step: Once the streaming profile is configured, you can upload your videos
> Media management / Video files:
- Click on “upload file”
- Once the file has been dragged (or selected), you view the upload gauge (different from transcoding) => the upload time varies depending on your internet connection.
- Then the file will appear in the list.
- Until the transcoding is complete, you will see the “pinwheel” icon on the right.
- Do not hesitate to click on the "synchronize" icon to update the status of the videos.
=> It is not useful to load very high resolution files, favor files in mp4 format, this will allow the transcoding to be carried out more quickly and it will also take up less space on your storage space.
=> Recommended formats for video upload (optimized encoding and quality): MP4/H264 with a resolution at least equal to the 1st preset selected (in your encoding presets), i.e. 1920x1080p / 4.5Mbps if you keep the default presets .
=> Approximate transcoding times: for an mp4 file at 8.5 Mbps with 3 outputs (2HD + 1SD, default presets), allow around 6min30 for a 10 min file and 40 minutes for a 1 hour file.
> Media management / Bonus files:
- File that will be attached to the video on the platform and that your users will be able to download;
- Can be any type of content (pdf, jpg, png), such as presentation booklets, training materials, additional documentation...
- Maximum size 8MB;
> Media management / Subtitles:
- Either your subtitles are directly integrated directly into the video, in this case, you have no other action to perform;
- Either they are independent files that must be loaded in this section, you will attach them later to the corresponding video;
- Only VTT and SRT formats are supported
