I'm importing videos and video thumbnails from a legacy site. A lot of video thumbnail have black boxes at the top and bottom due to the aspect ratio of the videos, for example:
I would like to crop all video thumbnails to remove those bars. I haven't done it yet but assume it's pretty easy to just modify the image style for "thumbnail".
Now, any new videos that will be uploaded (using the video module) or any of the images that use the thumbnail style don't need to be cropped that way. If I would change the image style for "thumbnail" after all videos are imported then I would lose the crop effect, right?
How can I solve this problem? I'm displaying all video thumbnails using views. Do I need to do a template override where I manually apply a different image style to those "legacy" videos?
