On the Video that you sent me, I found two still images that had the issue that you are seeing. When LR creates a Slideshow, It works with the original image. While in LR, it views an image from previews. These bands indicate one of two things. Your disk drive where the originals are stored could be failing and the originals are corrupt. OR the RAM where LR builds the derivative image before creating the video file could be going bad. If the same images are always created like this, I would suspect the disk drive. If different images show up like this each time that you build the video file, I would suspect bad RAM. There ia an app called "meatiest" that you can find on line, D/L and run to test your memory. I would do that next. If you suspect a failing Disk Drive, you might try restoring these image files form your backup copy.I am using LR slideshow exactly as I did in LR 5 where it always worked successfully. Now with LR 6, I type in standard text in the Metadata Caption space, no special characters, on most photos in a folder. Then I put the folder in Slideshow mode. When I Export PDF Slideshow, each photo is displayed with its corerct caption. When I Export JPEG Slideshow, each photo is displayed with the last photo's caption in the folder. I tried everything I know to do including removing the caption in the last photo. Then only the " " marks are displayed for each photo where the caption should be. This is very strange. The JPEG slideshows are usefull for me when I want to project a slide show from another computer or flash drive, or print individual photos with the caption. Thanks for any help you can suggest.
The "Use Graphics Processor" is unchecked, but I don't calibrate my monitor.
I'm not seeing the banding in any of the LR modules, only in the exported videos. I took the computer to my computer guy who upgraded my video graphics card last summer to see if it was the relatively new graphics card causing the problem. He used his own monitor and ran several small mp4 video exports of some of my pictures using different video graphic cards. Each export resulted in color banding on random slides.
For the presentation, the projector (an old Infocus) was connected to the computer where the monitor had been connected. The detached monitor cable was plugged into the projector so I could watch on my monitor what was displayed on the projector screen. Again there was no color banding as I was playing it right from LR on my desktop computer.
Damned Autocorrect!!!. That should be "memtest". It is the same program that your specialist will use. All it does is read memory and generate a report You can not make matters worst by running it,I couldn't find the app, Meatiest, to test the RAM, but it is probably better to have a computer specialist do it
