Topic: Putting cuts in a synth

Report Abuse Report Abuse

I'd like to be able to put a cut in a synth - i.e. jump from one P.O.V. to another. Is it possible to disable the 'matching error' flag in the processing that forces rejection a change of scene.

I realise that this isn't something that you would want to allow for most uploads - but I would like to get creative. So maybe a (non-public) keyboard shortcut to allow this?

@H Gregg, it seems like you are asking for two totally unrelated scenes to be in the same synth. Is that right? Essentially wrapping photos for two (or more) synths into a single one?

With Photosynth 1 (the desktop application) you could upload unrelated scenes together in a single synth and, once online, use the period + comma keys to move through the photos in filename order (which would take you from the end of one sequence to the beginning of the next). 

Photosynth 1 also already has support for 'Highlights' (the thumbnails on the right hand side of some synths + panos) which will take you from your current position in the synth to the portion of the photo specified in the selected highlight. In a synth where all photos are connected, an automated path through intermediary photos would quickly be calculated and followed to the highlight. In synths with unconnected photos you would transition immediately to the highlighted photo unless you were in its cluster.

The point of a synth is to upload photos that will spatially connect, so I don't know that trying to force unconnected sequences into a single synth is such a good fit.

Some months ago I suggested playlists of synths for Photosynth 2 while we wait to get linked synths in our hands to use http://bit.ly/psfps2p and the Photosynth team seemed interested in making that happen, going so far as working on getting synths to load onto an already loaded viewer as preliminary work to implement playlist support. (See Henri Astre's blog about his Chrome extension http://bit.ly/psctblog "it’s using a new version of the viewer capable of quickly unload/load synths" the second reply from the Photosynth team in this topic http://bit.ly/psfaspect .)

I believe that would give you result that you're wanting, as long as the playlist has some concept of scrubbing back and forth in the context of the entire playlist, rather than merely the currently loaded synth.

Also, highlights are due to make a return in Photosynth 2, as indicated in this earlier discussion where Joscelin asked about them: http://bit.ly/psfps2highlightsj

It's not been talked about yet, however adding highlights within a playlist could also be an interesting way to create the equivalent of CD track divisions or DVD/Blu-Ray chapter divisions (beyond the basic chapter divisions of the end of one synth and the beginning of the next). I think that this would be a good way for playlist authors to show viewers what they wanted to focus on in the context of the playlist, rather than necessarily depending on the synth authors' own highlights from the individual synths bubbling up.

Hi Nate - thanks for the info. Yes I want to put spatially disconnected sequences together. But they will be connected with a storyline. I'm toying with the of making very short animations in Photosynth, and I want to put cut-aways in.

As spin sections seem to work pretty well in a walk I figure it could make quite an interesting synth it cuts were added as well.

It should also be more appealing to a wider audience - people are used to VERY rapid cuts these days (adverts - MTV) so things are perceived as slow without them!

I don't think somehow that this will be priority for the team so I might have to find a way to cheat PS into submission ;-)
NateLawrence (11 months ago)
Good luck with the cheating angle. ;) 

The most obvious way to me to do that would be to use the last frame of the first sequence and the first frame of the second sequence and create two or more intermediate steps of cross fading between them and additionally rename all the files and edit their time and date metadata so that the photos will be read/sorted in the desired sequence.
HGREGG (11 months ago)
:-) Great minds! Yep that was pretty much where I was going and taking the merged frames as close to black as PS will handle.

Thanks for the tip about metadata - I hadn't considered that!
