@dan19936 your post is some interesting information:
Is there some place where I can read up on this?
Is it possible to do this (specify timeline to play( if I am hosting the file?
Can I specify both the start and stop frame/time?
It would also be interesting if there was a way to do this with the SU viewer on a web page and if the SU Viewer had a link to play an animation without having to got through all of the steps like now >View >Animation> Play. I would like to see just a Play button in the toolbar if there were scenes set up as an animation. Again, it would be really cool if you could use the viewer to play an animation on a web page (perhaps without the viewer not even having to download the viewer - just click a link and have if launch).
For now though, my real emphasis is on understanding how to play part/parts of a video file from a web page. I have done entire videos before but honestly was not aware of the ability to specify a starting point and perhaps an ending point. I can really see some use for this especially if I can host the video on a web server.
