HyperCaster 4.0 and above includes a Transmux feature, which will look for any MPEG-2 Program Stream or MP4 mux containing H.264 (including most .mov formats) video, and transmux those to the MPEG-2 Transport Stream format required to play out on the HyperCaster.
The Transmux feature also makes it possible to import a DVD.
Import a DVD
- Create a new Folder in the DVD_Import directory with the intended filename once imported, like Football-02232017
- Drag the entire VIDEO_TS folder from the DVD into that new Folder
- It will then autoname the final file based on the folder name
- If you name a folder with a “+” symbol at the end, the importer will join multiple titles into a single file. Otherwise the default is to import each title (if multi) into separate files
More detailed DVD Import instructions, here.
On import, the HyperCaster will re-multiplex supported MPEG-2 Program and MP4 files on import to Transport Stream.
This produces a variable mux rate output. Video is preserved as-is from the original file including video bit rate. Audio is preserved as-is from the original file including audio bit rate for AC-3, MPEG-1 Layer II, and AAC audio. Other audio formats are converted to MPEG-1 Layer 2 for MPEG-2 video, and AAC for H.264 video.
(NOTE: If utilizing the transmux feature of the HyperCaster, first please confirm that the audio formats above are supported by the end decoding devices; IE: Set Top Boxes, TV Tuners, Other Broadcast Decode Solutions. If these audio formats are not supported, you will need to use an external file prep solution such as TeleStream Episode Pro or TelVue Connect.)
To enable the Transmux feature, go to Config –> Content –> Content Item. Check off the box “Transmux to Transport Stream”.
If you do not have the Transmux feature enabled, the HyperCaster will still import MPEG-2 Program and MP4, but will show the files as unplayable. The tool tip help with display the reason why, and note that you need to enable the Transmux feature so that the file can be transmuxed to Transport Stream for compatibility.
If you do have the Transmux feature enabled, MPEG-2 Program and MP4 files will still show as unplayable when they are first imported, but the tool tip help will show that it is waiting to be Transmuxed.
The transmux operation itself is fast, and does not require re-encoding the video stream, and also typically does not require re-encoding the audio stream. The original quality of your source video is preserved, the file is just reformatted to Transport Stream.
You can see the progress of the transmux operation in the Tasks tab.
If the HyperCaster is integrated with a TelVue Connect account, your and your contributors can upload the DVD content directly into the Connect Media Library, where it will be automatically transcoded to the proper profile and made available to distribute to your HyperCaster.
