Here is a little more robust solution, it is OSX only as it uses syphon. It takes a syphon feed (in and out), send it the image stream and it will return a freeze of an image, but also a path over osc of a saved png. It will save the png also with an OSC signal. All settings configurable through an XML inside the data folder. Leave the folder structure as is (you can put your izzy file where ever)- default image save location is inside the data folder but can be changed as with all other settings. Make sure you set up the save location, and image size. To load the images into Isadora later use an apple script- somewhere on the forum. The image saving is threaded and should not interrupt anything but it is a little weak in that if the thread is busy saving an image it will not accept to save a new image- so you have to wait for it to be done before you can save another- still I can do 10 a second (should not crash if you do it too fast, it will just complain to the console).

Apple pro res. Sorry.. late post 😛

Dear levranido,

What version of Isadora are you running? Best Wishes, Mark

same as Rick for me
thanks Mark

Yes!

I removed the component as recommended and Isadora now launches properly. Thank you very much Mark. -Aolis

So my first live experience with Isadora at a Student (non professional) Performance in Vienna. Ideas from the fantastic workshop at Munich with Jamie and Mark are getting real.  Tracked with Kinect, NImate Ghost Image through Syphon into Isadora, music synced from Cubase with 1 Audio Track and 3 Midi Tracks (channel 1 every beat, channel 2 only first beat, channel 3 every second beat of the 3/4 time signature) Controlled via IPad and TouchOSC: 4 DMX Channels (DMX King), Mask Content, Image Multiplication, Switching Midi Trigger Channels

I did it quite quick. Now after seeing it, I would have liked to modulate the intensity of the DMX channels. Next homework: how to integrate processing in isadora (syphon?), but I think this is a separate post...

got it...

regarding SD, standard definition video. ok.-

yes, thanks a lot, it works with the core audio actors.

greets Marloeke

As always, if you're on Mac OS use the applet and send me the crash reports so I can analyze. For Windows users of the pre-release version, the crash reports are transmitted to me automatically. Make sure to include your email address an a description of the problem when sending on Windows.

The OSC crashing issue likely has nothing to do with the vblank-disable thing. They are really not related. Due to Troika Ranch's recent gig in Moscow and the even more recent Berlin workshop, I haven't been examining these crash reports. But will start looking them over them this week and get back to you as soon as I can. Best Wishes, Mark

Opps! I'm so sorry about the late response! I was in the middle of the production and forgot to check back to this thread after.

@Kathmandale
I totally thought apple pro-res would be such a heavy codec to playback on, so this is new for me! I can give that a try next time.

@Michel I was using the most current core version, my hard-drive speed is only 5200RPM, could this be the reason?  But I've seem this happen quite regularly even on generative things like 3D particle and Shapes moving, there are irregular stutters every once awhile. 

It really becomes an issue when playing on really big screens, it becomes quite noticeable. I hope this issue can be solved somehow. I'll try it on a SSD MacBook Pro next time to see if that's an hard-drive issue.

Thanks
Sammy

@Michel,

so I finally tried the patch (actually a while back), and strangely the video coming in was running at an extremely slow frame rate (although my input is SD).

Not being very good at QC I gave up.  At least this time I saw some video.

Thanks,

Ur,ummmmm..........................................eric

OK weird - now it opens fine, I was going to generate a new crash report... Attached is the former crash report though and the current prefs file.

Hello Everybody,

I just went through a back and forth with an Isadora user whose copy was crashing on startup under Windows 8\. It turns out, many, many graphic cards need to have their drivers updated before they will work with Isadora. (To see how pervasive this is, search Google for [ "Windows 8" minecraft problem ] and you'll see a hundreds of pages about this -- Minecraft also relies on OpenGL.) In the next version Isadora won't crash in this situation, but it will still show a warning because OpenGL is not available. But I've added this to the download page for now, and wanted to post it here as well: _If you upgraded to Windows 8 from a previous version, it is very possible that your graphic card drivers need to be updated. Make sure you have the very latest drivers before running Isadora._ The Microsoft Compatibility Center will check if your graphics card is compatible with Windows 8. To update your graphics card driver, follow the instructions on this page under To Manually Update Drivers

So please take note of this if you are a Windows 8 user, or have had problems with Windows 8.

Best Wishes, Mark

hello guys just to say that the f32 version has solved the problem... great news for my project...

Dear Callie,

Please report this as a bug using the bug report here: http://troikatronix.com/support/isadora/ Best Wishes, Mark

sorry for the late answear..but it works also with the blackmagic...
thx everyone

Glad you've sorted it 🙂

Dear lala, I'm guessing that the problem is with the HSL Adjust and Motion Blur. HSL Adjust is one of the heaviest actors there is; Motion Blur less so. If you are not interactively changing the color with HSL Adjust, then process the color in your editing software _before_ putting it into Isadora. Motion Blur might be harder to duplicate. Remember: you've doubled the resolution horizontally and vertically; that means those filters will run _four_ times more slowly. How many movies are you attempting to play at the same time? But the very first test you should do is to turn the 'bypass' on for all the HSL Adjust and Motion Blur actors. Then take a look at your playback. Is it acceptable? Then you know these actors are the culprit. Best Wishes, Mark

Since you don't route audio signals via wires in Isadora, it's tricky. (Unless you do use AU audio actors)
You can do a mono file and pan it to the left with movie player, so your sound goes out from one speaker only. If you want movements across several speakers, you have to premix them on multichannel audio file.
(But if you want to adjust you have to rebounce and remux your mix again.)

To do a multichannel audio file :

Export each stereo pair to an AIFF file (Front L-R, Middle L-R, Rear L-R by example)
1. Open first one with quicktime
2. Open second one with quicktime too
3. Select all on second audio file window (Cmd+A)
4. Copy (Cmd+C)
5. return to first audio file window (playhead at the begining of the file)
6. Add to sequence (alt+Cmd+V)
7. Do 2.3.4.5.6. with the third audio file
8. Now when you ask infos about first audio file (Cmd+I) you can see several stereo audio streams.
9. Save as...

Now you have a multichannel quicktime file you can open in Isadora.
Each stereo pair will be routed to each stereo output. (e1-2, e3-4, e5-6)

Best
Philippe

My solution of late has simple been to have a seperate computer with my control panel doing show control stuff and then one or more playback computers slaved to it. Not so helpful for you but even with 8-Core Mac Pros which is what I've been renting lately I tend to need multiple machines.
