Personally, I'm not a big fan of negative parallax (pop-out). The convergence on that video is pretty far away from the camera.. there's a couple shots of the road that show quite clearly that the convergence point is a good 15-20 feet away from the camera. It was actually throwing me off a little bit. For whatever reason, YouTube's interleaving is reversed from mine, so I have to hit the little "reverse left/right eyes" button on almost every video (not all, but most). And in this case, I actually had to do it several times to make sure I was seeing it properly because some objects still seemed a little "off".
I think one of the problems is that most of these shots don't have any particular focus. There's not an actor or object fairly close that the viewer can focus on. A lot of film directors will put the actor at screen depth, which can help focus the audiences attention, but that was missing in this case, and the convergence seemed almost random.. there really wasn't anything at that distance to lock onto.
Just personal preference, really. I prefer the "deep field" view, where my monitor is like a window into that world. While I don't mind occasional pop-out, I usually prefer it to be things that are actually closer to me than the screen (i.e. only a couple feet away, this is just a computer monitor). It's how I typically set convergence in the games I play in 3D.
But like I said, this isn't just me pissing about the video, I'm curious what others think about general convergence levels and what they prefer.
Trying to do some catchup work this week on older posts with comments.
First, I want to thank you for your specific observations. They mean a lot to me as I'm trying to learn what works best.
On row interleave viewing the left right is confusing. Even using my Vegas Preview on secondary monitor set for Line interleave, I have to swap the left and right for full screen viewing. I maintain the standard on the timeline of left cam on the left or top timeline when pairing. This keeps the SBS rendering consistent. I don't think this is a YT issue but rather how the TV's work.
The focus on an actor is an interesting observation. It seems to me that we all get used to a common requirement in presentations of 3D from Hollywood's dramatic stories about people, machines, single plants and animals and when there is a departure, it can be cause for viewer contusion. Those deep shots that begin in negative parallax and extend to well beyond the depth of the screen do not have any particular visual actor or focus. These I try to set the screen frame about center. Then when I view my screen my vision tends to wander rather than focus on everything at once. This dictates that I keep the scene on longer than normal to give the viewer that opportunity to scan around visually. But, not too long or too many shots adjacent to prevent boredom or eye fatigue. In a video like these desert shots and over water shots, these scenes are necessary to relate the story or the mood of how it does really look, being there. In a story like Bryce Canyon, there is very little that comes up to you because the long shots begin hundreds even thousands of feet away up to several miles, often 50+ miles! Here negative parallax becomes the exception in shots with no "actor" to focus on. Mostly Bryce Canyon views are through a window to the world of Bryce. Sometimes something pop's through the window.
When it comes to convergence preference, I prefer to let the story dictate where it is. As a story writer and as an editor, I do not want to set a rule to follow when in a creative session. To me Story is first and then comes shot picks that best tell that story. I trust the viewer will figure out the story and how to watch it. I don't try to set a goal to make all my work the same and don't want to be stereotyped to a collections of rules for my art. It is what it is and sometimes it is appreciated by more than at other times.
