Revisiting Video Navigation

[scottgarner]

Normal scrubbing at the bottom of the video unfortunately just won't work because Popcorn cycles through all events as it moves through time, so you end up with crazy problems like the video player suddenly jumping into the corner during the middle of your scrub,

Maybe we could do something like p5 and have a lesson timer at the bottom that isn't interactive? Or maybe it could be minimally interactive, where you could jump between the popcorn cues instead of to any time during the video?

This sounds like a good direction. Let's try adding the lesson timer, this will at least give people a sense of where they are which I think works well with the p5 video. Maybe, as you suggest, there could also just be a selection of clickable points on the timer that would allow people to jump to specific moments for a little more control? I don't want to overcomplicate things though.

Do you think I should try to visually represent a timeline for the whole hour of code or for each video at a time?

[shiffman]

I think maybe just each video at a time? We have the navbar at the top which gives people a sense of where they are in the full tutorial?

[scottgarner]

I think that makes the most sense to. I took an initial stab at this. I'm debating whether or not to try and move the video option buttons down there, but things get cluttered very quickly.

I think it's probably smart to stop where we are, the addition of a timer at the bottom is quite helpful. I'm tempted to say we add a couple markers that a user could skip or return to for key points, but I have a feeling that this may be too much and "cluttered" as you mentioned. Any last thoughts?

I like the idea of waypoints, too, but unfortunately jumping back and forth
with Popcorn is so erratic that things go crazy very quickly.

I remember now that the ten second button from last year was the easiest
compromise because there are relatively few events in a ten second span
that could go haywire.

I added the ability to scrub through the video using the bar at the bottom of the screen. I can see the issues with Popcorn's jumping that is mentioned above, but I think I've mostly fixed it in parts 1 & 2 as far as I see by adding relevant stop times to the events so they don't conflict.

amazing that's great, I'll try to do some testing and see if I notice anything!
