There is a new "fillcolor" option in the next Image Support module release that will support this - so instead of having to modify the module just add it to the URL or the template image call - i.e.
When cropping I'm not sure a fill color is used - are you cropping to a smaller size than the image size to get "borders"? Let me know how you're using it so I can check it out.
If it was easy to tell you "what you are missing" we would have already done that
There's a server issue that is affecting your conversions. If you can give me root access I can tell you what it is - you need to send it to support [at] jamroom [dot] net, along with the URL to your Jamroom site and the master admin login.
No - it should "just work" for the most part. I would need to have your root login and site admin login - I will tell you what the issue is. Send it to support [at] jamroom [dot] net.
No issues here with that video - it converted in under 2 seconds. So something is messed up on your server. Unfortunately it can be tricky try to figure out why the server is blocking conversions from the FTP/web level. Do you have root access on your server?
