In an epic face-off against x264, MainConcept triumphed with 2X faster encoding

Endeavor Streaming, a large OTT platform provider powering streaming services such as UFC FIGHT PASS® and WWE Network®, didn't have any data to suggest that their open source codec could be improved upon.

“We had no problem using open source in principle, but we decided there's no downside to seeing what MainConcept could do,” said David Salmon, CTO of Endeavor Streaming.

MainConcept accepted the challenge, running a face-off between the new MainConcept AVC SDK 11.1 (H.264) and the open source incumbent, x264. The results show that not all codecs are the same: 


2X Faster


50% Cost Savings
on encoding-related server runtime


Same High Quality
as before

“Frankly, we were shocked by the results, we didn’t expect to see such a dramatic improvement in performance,” says Salmon. “Not only does this make our platform faster, but the cost savings are significant–over 50%.”
