Fix the viewing of video files with the storyboard and conversions.

Steps to reproduce:

• Navigate to a workspace
• Click on create button and select video.
• Add title and click on upload main file and select sample video file.
• Click on create button.

Expected result: The created video file is viewing properly with the storyboard and conversions.
Actual result: The created video file is not playable and shows a black screen, no storyboard, and no conversions.

Note: To view the video file, storyboard and conversions, you need to refresh the page several times.
