How Fast-Forward Preview Thumbnails Work

Fast-Forward Preview thumbnails are supported by all Tablo applications except iOS devices (iPhones and iPads).
 
Thumbnail images are created after the recording is completed. On legacy Tablo devices, this is done by re-processing the recording using one of Tablo’s available tuners. That function is done in the background on 4th Generation Tablo devices without requiring a tuner.
 
Either way, this additional processing means Live TV and in-progress recordings will not have any Fast-Forward Previews.

An hour-long recording should show Fast-Forward Previews approximately four minutes after the recording has finished. Longer recordings will require additional time for processing.

If multiple recordings finish at the same time, these will be processed sequentially, and it may take longer for Fast-Forward Previews to appear.

Legacy Tablo users could see additional delays while the device waits for an available tuner. 

 

Why You May Not Always See Fast Forward Preview Thumbnails on Tablo

There are several reasons why your program may not show Fast-Forward Preview thumbnails, including:

  • You are watching Live TV or an in-progress recording
    Only completed recordings will show thumbnails, and only after the recording has been processed to create the images.
  • There are errors in the original broadcast stream
    Fluctuations or blips in the signal coming from your TV antenna to your Tablo can cause errors in the video, which can lead to failure of the Fast-Forward Preview creation process. Improving your TV antenna setup can help if this happens frequently.  
  • Your Tablo is busy with other tasks
    If your Tablo is busy with other tasks (or on legacy Tablo devices if no tuners are available), your device will wait until those tasks are completed before processing Fast-Forward Previews. 

It is possible to reprocess a recording by rebooting your Tablo device.

During the boot-up process, recordings without Fast-Forward Previews are identified and a second processing attempt will be made. However, if there is indeed an error in the recording, it’s unlikely this will be successful.
