Pre-transcoding Files

Pre-transcoding your media files is a feature unique to Mezzmo where you can prepare any incompatible files before streaming them to your devices in your home. This allows for smooth playback on your devices and less CPU activity on your computer.

In general, you don't need to worry about pre-transcoding your files. Mezzmo looks after any incompatibility issues by transcoding your incompatible files on-the-fly. You only need to consider pre-transcoding your files when they are not playing correctly on your devices.

Reasons to pre-transcode your files

How to pre-transcode a file

  1. Right-click on the file in Mezzmo and click Pre-transcode Files.
  2. In the Pre-transcode Files dialog, select the device(s) you want to pre-transcode the file for.
    Pre-transcode Files dialog
  3. Click the Choose Formats link next to the device to display the Pre-transcode Formats dialog.
  4. Select the format(s) that you want to pre-transcode to.
    Pre-transcode Formats dialog
    Tip: We recommend selecting the bolded format as this format is known to play well on your device.
  5. Optional: Select the Force full transcode of all channels checkbox if you suspect one of the channels is badly encoded. When this option is checked, Mezzmo will not copy (or remux) compatible channels but will fully transcode them. This takes longer to transcode, but may fix encoding problems in the original file.
  6. Optional: Select the Force embedding subtitles checkbox to force subtitles associated with the selected video file to be embedded into the transcoded video as embedded subtitle channels. This is useful if your device lets you choose and display embedded subtitles using it's remote control.
  7. Optional: Select the Force burning subtitles checkbox to force a subtitle associated with the selected video file to be burnt into the transcoded video. This is useful if your subtitles are not displayed at all, or not displayed correctly by your device. For example, you may have Korean external subtitle files but your TV is not capable of displaying Korean fonts or characters. So burning your subtitles will let you see these Korean characters in their correct form.
  8. Click OK to save your transcoded formats.
  9. Click OK to start transcoding. All files that are queued for transcoding are listed in the Transcoding pane in Mezzmo. We recommend waiting until your file has been completely transcoded before streaming it to your device.

Tip: If you see the message “No files were queued for transcoding since they match formats that are supported by the selected devices”, then Mezzmo will not transcode the file(s) since the original file(s) should be supported natively by your device. This is based on the device profile assigned to your device in the Media Devices dialog in Mezzmo. Device profiles contain the formats that your device supports and the formats that Mezzmo should transcode to. To override this, you can select the Pre-transcode files even if they match the device's supported formats checkbox and then click OK to start transcoding.
