I am a frequent user of Box for viewing recorded training sessions. Since the recent video player update, the "Fit to Screen" / "Aspect Ratio" is not functioning correctly. The video remains letterboxed/small and does not utilize the full browser real estate.

 

Steps to Reproduce:

  1. Open any recorded .mp4 video in Box web preview.

  2. Click "Fit to Screen" (bottom right corner) 

     

  3. Observe that the video player does not scale to fit the viewport.

Current fit-to-screen Full screen:​ (Observe that the video player does not scale to fit the viewport)

Expected Result:  The video player should intelligently scale to fill the available screen space without cutting off content.  

Expected fit-to-screen Full screen :​

Hi ​@dheerajnaik19

Welcome to Box Community, and we’re glad to assist regarding your Box preview! 

  • Is this recurring in different browsers? 
  • Is it recurring in all video files in Box.com?
  • Could you download the file? Would it display the video file correctly?
  • What is the file extension?

We are looking forward to hear back from you!
