Lightroom 4 video black thumbnails and playback

Apr 1, 2012 9:47 AM

Tags: #black #video #playback #thumbnail #lr4

On loading I see thumbnails for avi videos for about a second and then they go black. On playing in Lightroom the screen is black but the sound is fine. The videos play correctly in Quicktime and other programs.


Any suggestions on how to fix this?

    My first suggestion would be to check for updates to your video drivers.

    4.1 shows avi files as black thumbnails and plays only sound. Installing a full codec pack did not solve this. Changing the codec to a different one or converting to another video format solves this. These files are from both Canon and Fuji cameras and play fine outside of Lightroom.

    Thank you for your reply.

    I am concerned before i start converting outright why it does not play. Many of these vids were created in Adobe Premiere Elements 4, 8 & 10 so they should work seamlessly. The others were done with various canon & sony cameras.


    I would prefer to try to install the codex pack BUT I am not sure what it is and where to get it.
