Play any media file, from anywhere, in a browser with GLIM

Supporting television production and media distribution while teams work remotely brings with it many challenges. A primary challenge with remote work is the ability to see, hear and understand the technical properties of your media library from afar. At Telestream, we call this media file opaqueness.

GLIM was built to solve well known remote work challenges: be a vastly superior experience to the ‘remote desktop/virtual desktop’ play back experience, and to prevent remote employees wasting hours every day downloading mezzanine grade media files. Solving these two challenges significantly reduces the aforementioned media file opaqueness, and ultimately increases productivity.

The GLIM engine is built for remote playback of any container / codec / resolution / fps /audio channel / colour space combination in a web browser (Windows or Mac OS and Google Chrome v80+).

GLIM Firmware version 1.2 additional features: 

  • The main improvement is a revamping of the settings system to avoid hand editing JSON files for almost all customer cases. Instead the settings have been moved to a web GUI accessible by admin folks who have access to localhost (either via remote desktop or physically).
  • Ability to render interlaced content in f1, f2, weave and split side-by-side fields for QC
  • A simple built-in load balancer so that customers can put a group of GLIM severs together to handle higher client counts
  • Ability to see Nielsen watermarks applied to a clip
  • Title safe overlays
  • Dark mode
  • Ability to see SCTE markers
  • Ability to skip forward into unindexed content to save time in spot checking workflows
  • Ability to go-to a timecode location

Playback capabilities:

  • Supports playback of any media file Switch or Vantage can play or decode
  • Play head scrubbing and frame stepping with keyboard shortcuts (J/K/L/Arrows)
  • Allows for surround mixdown and surround output from multi-channel audio (5.1) source material
  • Selectable audio channels: users can listen to any channel present in the source media
  • Displays ancillary data from media files: timecode, closed captioning (608/708 all services)
  • Image file playback/display (.dpx, .tiff, .tga, .jpg, .gif, .png, .bmp, animated gifs)
  • Audio only playback (.aiff, .wav, .m4a, .mp3, .f4a, audio only .mov)
  • Allows sidecar caption files to be loaded and played against the source material (SCC, SRT, TTML, VTT)
  • User video quality selection: each user dictates the quality of media they are delivered

GLIM has been designed and engineered to playback high resolution and high bit rate media files over very bandwidth constrained internet connections (example: working from home while connected to corporate VPN).

  • The GLIM client side bandwidth requirements are configurable (2-8mbps commonly used)

GLIM leverages proven standard technologies to display media in a browser that requires no additional software to be installed by the client.

  • The GLIM engine can be configured to leverage HTTP or more secure HTTPS protocols (operates on port 5000/5001 by default)
  • GLIM supports multiple user authentication schemes including Windows Active Directory
  • The GLIM engine allows limiting the access to predefined browsable directories

The GLIM engine contains a plugin architecture to interact with Vantage and other third party systems via web service (REST) calls.

  • GLIM ships with sample plugins to submit media files and variable transmission to existing Vantage systems
  • Allows the sharing of media file playback links (with UI configurable in/out points) with other users in your organization
  • Allows for high resolution images of the source media to be downloaded and shared

A single GLIM engine supports playback from multiple users.

  • Individual computers and bespoke playback tools are no longer required to inspect and play mezzanine grade media files

The GLIM engine runs on Windows Server 2012 R2 or Windows Server 2016.
