Well, if you have an example patch you can send, I'd like to take a look. Thanks in advance. But it somehow sounds like a feedback thing -- were you doing any kind of feedback (output of Alpha Mask back into the Zoomer) in some way?
I received a message from mark in the past that says:
"No, unfortunately Core Video is an Apple-only technology. When we get FreeFrameGL into Isadora (in the next couple of months) then you'll have similar capabilities in Windows."
actually, this is what I am asking for.
i did some testing. the preview size looks good if no external monitor is connected. as soon as i do connect an external monitor the preview is deformed.
this is happening on mountain lion as well as on my old laptop with snow leopard.
i´ll be sending you the testfile right now.
thank´s, all the best,
I would like to debug this file. Regarding Scene 2.2, I would like to know the following:
1) The resolution of movie 29 = VI blev til et-cm.mov
2) The setting for "Default Resolution" in the Isadora Preferences, Video Tab.
3) Any crash reports you have.
You can use the applet on [this page](http://troikatronix.com/troikatronixforum/discussion/65/bug-reports-guidelines#Item_1) to get the crash reports. You can email the zipped file to mark [atta] troikatronix [dotta] com.
I frequently use more than one camera, and for some shows up to 4 cameras. Have had the same problem (black screen), and have solved it some times by choosing a camera, then if it doesn't show the image, choosing 'none', then re-choosing the camera. Otherwise I have to choose the resolution that it will accept. My computer has 2 USB ports on each side, and I have found that I must separate 2 of my cameras or only one of them will work.
Regarding lemond's comment
_So if you experience weird behaviour like this, always keep in Mind that Izzy tries to execute a scene from top to bottom..._
This is one factor. But the real root of the problem was his secondary scene had a Keyboard Watcher and a Jump actor -- and didn't realize that these actors were attempting to Jump at the same time as the Jump actors in his main scene.
It was short notice when it came to doing the show and I figured the version I had would do, as it served me well in the past.
I have total respect for the software and I know it was my prep leading up to it that is at fault.
I will get new version when I get home. attached is crash report.
Thanks for all your help
The values need to be managed at the channel level. For each channel there is a flag that says if it is HTP or LTP (set in the"edit channels map" window). Each channel also maintains its own list of values - one value for every active Matrix Value Send (MVS) that contains that channel.
When a new scene is activated, all the values in the MVS are passed to the channels as well as the fade time. If a given channel is flagged as HTP, the new value is added to the list. It is then also checked against all other values. If the new value is now the highest value, the outputted channel value is then faded from the previous highest value to the new highest value in the specified fade time. If the new value is not the highest value it is still added to the list but there is no change in output. Similarly, when a scene is deactivated, the value for the given channel is removed from the list. If that value was the highest value, then the output is faded down to the second highest value in the specified amount of time. If the value was not the highest value then it is simply struck from the list and there is no change in output. If there are no other values in the list, then the value can be faded to zero. This behaviour can be consistent with scene activate/deactivate as well as jumps. If a value is changed manually within a scene (or with an envelope generator, etc) then the same check for highest in the list can be made and the output changed in real time (if necessary).
If a channel is flagged as LTP, then the values for that channel are stored in order of activation. When a new scene is activated and the MVS contains the channel in question, the new value is added to the list and the value is faded from the previous latest value to the new latest value over the specified time. If the MVS does not contain the the channel in question then no change is made to that channel. When a scene is deactivated, the value from that scene's MVS is struck from the list. If that value was the latest value, then the output is faded to the second latest over the specified fade time. If that value was not the latest then it is simply struck from the list with no change in output. If no values remain in the list then the value is faded to zero. If a value is changed manually within a scene (or with an envelope generator, etc), then the value is immediately changed to that value and that value then becomes the "latest" value.
Hopefully that makes some sense.
For what it's worth: some of you installing the 1.3.0f32 or f33 pre-release got a message from the installer saying the version you were installing was **older** than the one that was already installed. The reason for this is that, on Mac OS X, the lowest part of the version number (i.e., the f31, f32, or whatever) rolls over at 32\. So, even thought I'd called it 1.3.0f32, the installer thought it was 1.3.0f0.
Thus the update for the new pre-release to 1.3.1f02.
Live and learn.
I've tried using a lot of various CODECs (AIC, h264, Photo JPEG, Anim, and DVCPro). I find that there is little difference in performance between AIC and DVCPro so I use DVCPro. I've never been able to get HDV to actually show a video - while the Quicktime app will play back the HDV compressed vids, dropping them into Isadora just shows snowy thumbnails in the player and nothing on the stages - so I don't use HDV.
All vids are native 1280x720.
These are playing from 2 different OCZ Vertex SSDs which have a 6Gbps interface (550MB/s read speed). 2 720p vids playing from one drive and the other two from the second SSD.
As mentioned above, I get this problem even when I'm just turning on the stages to go to an RSS feed scene with no videos whatsoever. It just seems like the stages don't like to come up very quickly no matter what I do.
I've started a new section in this forum called "Knowledge Base" where commonly asked questions like this can be answered. Your question prompted my first addition to this topic.
