Is this possible? Are we able to export them into an editing software? Are there plans to add an editing module? I would love to use this for a video tour within a home, but would need to include several synths with transitions. Is it possible? Is this possibly where the technology is going?

Hello,

You could capture your images on a room by room basis, upload them to the Photosynth service and them embed the Photosynth player on your website I guess - But please check the T&C's when it comes to commercial use.

Thanks

Matt

It's a good idea, Alena! 

I had a similar idea a couple of weeks ago: http://photosynth.net/discussion.aspx?cat=00581351-82d8-438d-a37b-7eadb3fb4991&dis=44f85ba7-2f47-4881-9b46-8802d18cd023

There is a video file preview of every new photosynth that is auto-generated along with the rest of the files and will display on devices which do not have WebGL support. If you share any of the new photosynths to Facebook via the second icon in the lower left corner of the new viewer, you'll see this in action and the video will be played in an Adobe Flash video player.

On other sites, an HTML5 video player will play the video and saving the video of the synth is as simple as right clicking and choosing Save.

With the videos of your synths, you could use any video software you are comfortable with to edit together a tour, so long as you shot the transitions.

As far as your question of whether linking multiple spins, walks, walls, and pans together is where the technology is going, in some sense, that is where it is coming from.

The first Photosynth from five years ago allowed us to shoot all the photos and link together many more than 200 although navigation was often too complicated (because of the total freedom allowed in shooting the original photosynths). 

Try viewing this synth which covers an entire house as one might view it in a real estate setting: http://bit.ly/blueridgehousesynth
After it loads, touch the photos with the mouse, then use the [T] key to see that Photosynth has generated a floor plan.
Period key [.] = Next Photo
Comma key [,] = Previous Photo

::

In another sense, though, linking overlapping synths (whether from the same user or different users) is a long standing dream of Photosynth - one that has not yet been fulfilled. Read this discussion from 2008 October 1st: http://bit.ly/synthlinking

As to using photosynths in a real estate setting, I would refer you to Frequently Asked Question 33: http://photosynth.net/preview/help#FAQ33

"Can I use my synths commercially?
Yes. If you have real estate, businesses, locations, or products you want to promote, you can create synths using Photosynth and embed the results in your website or blog. Currently, we do not offer an enterprise version of the product, nor do we offer any form of access control. Using Photosynth is a great way to promote a place or product publicly, but not the right choice if you need to closely control who can see your synths."

If you are using Internet Explorer 11, in order to save the video of a synth you can follow these steps: 

1: Press the [F12] key to open Internet Explorer's developer tools.
2: Choose the [Emulation] tab (lowest on the left side of the tools)
3: Change 'Document Mode' to 10 (this forces the browser to render the page as Internet Explorer 10 would. 
(Since Internet Explorer 10 had no WebGL support for 3D graphics, you will get the HTML5 video player instead.)
4: Right click on the video and select 'Save video as...'
5: Choose a folder to save the synth's video in and give the MP4 a unique file name.
6: Repeat with additional synths.

Tip: If you want to get the F12 Developer Tools out of your way, you can Unpin the panel and click back on the browser or minimize the developer tools to the Windows taskbar.

The document mode should change back to 'Edge' when the browser is closed and reopened, so you'll need to follow these steps again the next time you save videos.

Neat trick Nate.
PhotosynthTeam (6 months ago)
Great thread. We agree that giving owners easy access to the video files is a good idea, and is simple, so expect this one. Until then, use Nate's trick.

Even better than that would be connected synths, right? Of course, exporting a single video from a set of connected synths is tricky...
alenajenkins (6 months ago)
Awesome trick Nate. I will definitely be playing around with this in coming months. Realistically PhotosynthTeam, for professionals like myself I am just happy to be able to save the files and have my editing guy go to work on them. Really exciting stuff. Can't wait to try it out. 
Thanks all!
NateLawrence (6 months ago)
@Photosynth Team, yes! Connected synths are verrrry welcome!

@Matt and Alena, I'm glad to have told how to save the existing video file but bear in mind that it isn't the highest bitrate there is, so your video guy might actually want to just load the synth up on a high resolution monitor and a video card that has plenty of power to play it back and record it himself.

Maybe he has an amazing PC which can pull this off, but generally speaking I don't recommend trying to run a demanding graphical application that you want to get good performance from (in our case the Photosynth viewer) and also trying to run screen recording software which is capturing high bitrate video to a hard drive on the same machine at the same time. Hopefully he has a second box that can record HD video as the synth is played back on the high end PC.

If you do go in for recording synth playback yourself, here are a couple of notes: 
:: When moving through a synth, you are not using the highest resolution of the photos available (and there is nothing we can do about this as users), so there will be an upper limit to the effectiveness of higher resolutions that video can be recorded at. Source: asdf

:: The resolution that you load the synth at is the resolution that it will continue to render at after you have changed the size of the browser window (by maximizing, restoring, shrinking, or using fullscreen) so when the goal is recording a synth's playback in the highest resolution, you'll want to:
1: use a monitor with the target recording resolution, 
2: enter your browser's fullscreen mode [F11] on the synth's view page first and refresh the page once so that the viewer is then rendering at the monitor's resolution, then use the viewer's Fullscreen to hide the left icons.

@Photosynth Team, some requests:

1: Might we get an easy way to turn off the Play + Fullscreen icons in fullscreen for recording our own videos of synths?

2: I found the Inertia slider in the 42 panel in the earlier viewer to be exceptionally useful in playback of a synth as I could give the viewer a small nudge + glide through the synth at the speed of my choosing which is preferable for consistent speed at a more relaxed pace when recording video. Might we see this return, please?

3: Also useful would be a way to use Seadragon tiles of a resolution sufficient to fill the full screen with ≥ 1 pixel of photography per 1 pixel of screen in playback + ensure that this is always loaded for the next picture before crossfading to it is begun to be rendered. Since this is for recording video of the synth, it doesn't matter if this would have to be done at a lower playback speed as the video's frame rate can be sped back up in editing after capturing the desired detail.
PhotosynthTeam (6 months ago)
Before we embark on a series of mini-features designed to support people making their own high resolution videos I'd need to be pretty sure that this was going to work OK for people. What screen capture technology is proposed here?

(Note to Nate. Re #2 above. We'll probably get that one back in. And re 3: if you have a powerful GPU, then you can get higher resolution "motion frames" using the "preset GPU" option in the 42 menu.)
NateLawrence (6 months ago)
@PhotosynthTeam, thanks, looking forward to Inertia slider returning.
Also, thanks for explaining what the GPU preset setting affects.

As for an option to hide the Play and Fullscreen icons, there could just be a checkbox in the 42 panel under 'UI' to hide them in fullscreen.
That way most users will never see it and anyone who flips them off will still have access when not in fullscreen even if they forget how to turn it back on in fullscreen.
It would be even less of an issue once you get 'reset viewer settings to defaults' functionality in there.

For that matter, with Christoph working on getting export functionality in SynthExport for v2 synths, it may be that someone can simply make a plugin for Blender, 3DS Max, or Maya to render our own full quality videos without bothering you guys about hiding the UI.
NateLawrence (6 months ago)
As for video capture tech, I assume that Camtasia and company will continue to do whatever it takes to work on Windows, etc. 
Outside of software, plugging the video out of one's computer to a video recording card on a second PC or a dedicated HD video recording box would continue to be a viable option.
