Case Study: Udemy achieves 215x increase in encoding scale and near-zero errors with Brightcove Zencoder

Udemy Grows Video Offering with the Zencoder Encoding Service from Brightcove

Udemy, an online learning marketplace where instructors publish courses across business, tech, arts and more, rapidly expanded its use of video as a core engagement tool. As instructors submitted thousands of varied media files, Udemy’s homegrown encoding system struggled with reliability and scale, consuming engineering time and producing frequent corruptions that slowed course publishing.

Udemy moved to Brightcove’s Zencoder cloud transcoding (with Amazon S3 storage), eliminating costly hardware and freeing engineers from encoding troubleshooting. The change cut encoding errors from about 10% to under 0.1%, increased output renditions by 215x, sped turnaround so instructors could publish faster, reduced corrupt videos, and allowed the team to focus on product growth and mobile expansion.
