BYU-Idaho Supports Online Learning with Automated Video Transcoding

video transcoding

Brigham Young University-Idaho has automated the process of converting videos created by professors into formats required for online viewing, and the system has processed more than 13,000 video assets in the last year and a half.

Online Learning Strains Video Production Capabilities

BYU-Idaho currently offers four online associate degrees, 10 online bachelor's degrees and more than 100 online courses, and it's working to expand its online course offerings. Some faculty members are also using video-based tutorials, lectures and course materials to augment traditional face-to-face classes, and the campus is home to a large broadcasting facility. Professors create their own videos and send them to the university's in-house video production facility to be converted to the required format for online viewing, and the large volume of videos was straining the capabilities of the facility.

"It was becoming very apparent that the number of videos we were creating was just going to skyrocket, both for content for academic use and content for production use," said Michael Jeffs, media support specialist in the A/V Production and Broadcast department at the university.

Jeffs and the team at the video production facility began searching for a transcoding system that could easily convert large numbers of faculty-recorded videos to a format for distribution and viewing on a variety of device types.

Video Transcoding and Workflow Automation Solution

BYU-Idaho is affiliated with The Church of Jesus Christ of Latter-day Saints. According to Jeffs, the church's headquarters in Salt Lake City, UT, "probably owns one piece of gear from every major vendor there ever was," so the university video production team met with the church quite a bit to test the various transcoding systems that were available. When the staffers saw Telestream Vantage, they were immediately impressed. "We took a look and said, 'This is what we need! This thing has every bell and whistle and will make our lives so much easier!'" said Jeffs.

The video production team had previously used some of Telestream's other products, including its Episode multiformat video encoding desktop software; Pipeline network-based video capture and ingest system; and ScreenFlow screencasting and video editing software. While the university's previous experience with the company wasn't a primary factor in its decision, Jeffs said it helped because he and his team were happy with the company's other products and knew they could expect the same level of quality with Vantage. "We've had a good relationship with Telestream," said Jeffs. "We've got quite a few of their other products, so we knew that what we were investing in was going to work."

According to information on Telestream's site, Vantage provides video transcoding and workflow automation for "file format conversion, device interoperability and workflow orchestration for multiscreen, OTT, broadcast, cable and IPTV distribution, as well as production and archiving."

Telestream Vantage's workflow automation solution was the key feature that set it apart from other transcoding solutions, according to Jeffs. "It was just easy to use," he said. "We're a small team here and we use a lot of students, so having something that's relatively easy to train people to use was a huge plus for us."

Streamlined Video Conversion Process

Telestream staff came to the university to help the video production staff implement two Telestream Vantage Transcode systems, each of which is paired with a Telestream Lightspeed server for GPU-accelerated video processing. The system integrates with BYU-Idaho's Kaltura content delivery network and Avid video editing system. "We use it for just about everything," said Jeffs. "It's kind of a central hub. All of our video content at one point or another runs through Vantage somehow."

Jeffs and his team set up about 70 different Vantage workflows that define the various transcoding processes to convert source video files to the required resolution, frame rate, aspect ratio and other technical parameters. For example, the biology, music and communications departments each have their own requirements for their video files, so the video production staff created specific workflows for those departments, and created other workflows for the broadcasting facility. According to Jeffs, the majority of the workflows are similar with one or two different tweaks, depending on the type of source video or which department will use it.

Now, when professors create videos, they upload them to a watched folder on the network where a member of the media transfer team can grab the files and drop them into the appropriate Vantage workflow. Vantage transcodes the file as specified by the workflow, and then it sends the file to the Kaltura content delivery network. "For the professor, it's super easy and convenient," said Jeffs. "They just drop their video into a folder and seems like magic to them when it pops up on the other end all ready to be delivered into a class."
