Just got my EX1R last week, updated the firmware to 1.10, and noticed in the release notes that a "major function updated" in 1.10 was

• Max. of 46 characters can be set for the title
• Checking a long clip name on the CLIP INFO screen enabled (Long-Display mode)

In my several days of test shooting I haven't seen where I would set or use these 46 characters. All of my clips are of the <11 character>.MP4 format. I've searched three different XDCAM EX forums and haven't found any info on this "major function". Any clarification on where to set and/or use these 46 character titles would be appreciated. TIA!

If you have the update installed you just go to "Clip" in the "Others" menu and "Prefix" to set the prefix. Initially it will look like a 4 character prefix but you will find you can add additional characters. It's easiest if you use the handle joystick to set the prefix.

Thanks, Alister. I had visited the clip prefix menu item, but since it still "looked like" a 4 character prefix I incorrectly assumed they meant something else. I should have tried stuffing more characters into the prefix. I also wish Sony would have explained this a little better in the release notes. Well, off to devise a new clip-naming scheme with the increased characters.
