Trouble with Capture Stage to Disk actor

mark_m

While we're on this topic just to remind you that there's one dialogue box in Windows which still doesn't scale properly to the display: it's the output-> compressions setting dialogue box. This has been a long-standing bug and is still present in the latest version. As you can see the dialogue box doesn't quite scale to be able to include all the options, and one cannot size the box in order to do so.
Thanks

I'm sorry, I take ownership of this oversight. I was aware of this and lost track of it. Thanks for the reminder. I'll get it I to the system right away so that mark can deal with it.

Yes, well, I'm not quite sure what to do about that. I'm just telling QuickTime to show the dialog, and it does what it does. Remember: Apple stopped developing QuickTime for Windows years ago. It's not high-DPI aware, etc., etc. So, there may not be a solution for this until we drop QuickTime and I implement this capture stuff natively on Windows. But that's down the pike a little bit.

"and the Record Stage Settings will all be stored with the Isadora document."

thanks a lot @mark, this feature will be very appreciate here. Btw, did the "quality" of the recording will be save too? ´cause for my purpose i have to change this setting every time i open isadora.

@mark

Oh yes, I see: I hadn't appreciated that it's a QT dialogue rather than an Isadora one. So no, I don't know what you can do about it!!!

Thanks

"I am testing in v2.5.2 right now, and I see no black frame at the start of the capture. My test was performed on a 1920x1080 source stage window, with the Record Stage Settings set to capture at a custom size of 1280x720"

Yes Mark, you are right, my mistake. The black frame came from video mixer that had no input for the duration of a frame – and then that cumulated to flicker.

No one ever complained before, but you're right that these settings should be stored with the Isadora file. For the v2.6 release, the codec, the frame rate, and the Record Stage Settings will all be stored with the Isadora document.

That said, my testing shows that this is setting is remembered as you don't close the file.

1) Choose Output > Compression Settings... 2) Choose Apple Pro Res 422 3) Capture, Capture, Capture... all movies are Apple Pro Res.

Thanks Mark, storing codec, frame rate and Record Stage Settings with the Isadora document is a great improvement. For an installation, it's very important to be able to have these settings pre-selected.

... oh, sorry, forgot to tell that I succeeded to make a scene like my original purpose was: "I’m trying to do a project where the realtime camera accumulates continuously to a video. The camera image is superimposed to previous takes from the same stationary camera – like “superimposed layers of the past with the present moment”."

The trick was to slow down the playback of the captured files and then "cross dissolve" these. However, the project seems unstable, crashing every 10minutes or half an hour.

Here's the crash report:

It's crashing in the process that accumulates images to write as part of the Capture Stage to Disk process. Any way you'd be willing to PM me your patch (or post it here if you don't mind) so I can run it and try recreate and solve the issue?

Thanks for looking at my issue. Here’s the patch:

livecapturetest++.izz.zip

There are 3 scenes inside the Isadora document.

First and second are the ones that don’t have the black frame issue (first scene is cleaned up with a macro, but otherwise the first and second are identical). But the first and second scenes are crashing, usually after around 20-30minutes.

The third scene is simpler with only two captures, doesn’t crash, but has this “black frame” issue – and for some reason starts sometimes accumulate files (instead of replacing the two files). If it didn’t have the black frame issue, I would rather use this patch. I tried using video delay actor (just 1-2 frames), which took the black frame away, but it was very processing intensive slowing down Isadora.

Thank you in advance!

I just want to add that, given my schedule trying to wrap up v2.6, I cannot promise how quickly I can get to this. I'll do it as soon as I can squeeze it in, but it might be 2-3 days.

No problem, thanks for letting me know!
