Chrome is causing Final Cut Pro X to become unresponsive and crash for some users by hogging video encoding frameworks, a noted video editor has claimed on Twitter.

Felipe Baez, Creative Director and founder of Cre8ive Beast has pegged Chrome as the reason many users have been experiencing massive slowdowns within Final Cut Pro X.

It appears Chrome is to blame, hogging necessary resources which brings Final Cut Pro X to a halt.

If you use FCPX, don't use Chrome. Well, if you use any editing app, don't use Chrome. Just discovered Chrome locking down the VideoToolBox framework and making FCPX REALLY slow and crashing. — Felipe Baez (@baezfelipe) June 20, 2019

"Just discovered Chrome locking down the VideoToolBox framework and making FCPX REALLY slow and crashing," Baez shared on Twitter.

Chrome at some point apparently accesses and monopolizes VideoToolBox, which is a low-level framework that gives Final Cut Pro X access to hardware-based encoders and decoders when working with video. When Chrome starts using VideoToolBox, it doesn't stop, which causes a problem for video editors.

Baez says he clocked the CPU usage at 300% and resulted in FCPX locking up and crashing. Once he quit Chrome and VideoToolBox was released, Final Cut Pro X was able to operate as normal.

This issue won't just plague Final Cut Pro X, it will apply to any video editors or transcoders that are relying on VideoToolBox for encoding, decoding, and transcoding. Chrome is a notorious resource hog, frequently occupying large amounts of RAM for Mac users.
