Unlisted simply means that only those who have the actual link to the video can see. it doesn't show up via search. I did that since it is not my video.
There is definitely some flicker going on. Not sure if it is due to the time interval between images or something else.
I am having my op system (WIN 10) reinstalled today so I will be down. But for your question, I masked the last TL in Youtube at the next box down from unlisted.
I will start some experiments using the 5DSR and R5 side by side and see is I can isolate the flickering. I think the 5DSR gives best results in movie mode.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
