installed the direct show filter for NotchLC on windows and I can play notchLC files in windows media player when they are AVI files.
Well, the Windows tool graphedt.exe is a developer tool that allows you to visualize a movie playback graph.
32 bit Version
When I run the 32-bit version, and select a NotchLC encoded AVI with the command File > Render Media File..., I see this and I can press the play button and the movie plays.
64 bit Version
When I try the same in the 64 bit version of graphedt.exe, I see this error:
The 64 bit version of graphedt.exe shows this as the graph diagram.
Note that there is a stream for rendering audio, but none for video. This would seem to prove that NotchLC drivers are not 64 bit compatible. And that means Isadora, which is a 64 bit app, can't play it either.
If you examine Windows Media Player, I am quite sure it is a 32 bit app and that's why it can play the files.
I have had better experiences using the Blackmagic design codecs (included with their video capture software - free).
However. At 5 mins you will likely hit the Avi containers max filesize... This will truncate your video.
I would use OBS to record a Spout feed from your stage. This would record realtime, so you patch needs to run smoothly in real-time. The nice thing about this approach is it off loads see work from Isadora, so you have more cpu space to use.
Tried many things like reinstalling Isadora or setting up a new session.
I have run a test patch on MacOS Catalina 10.15.3 for three hours using exclusively MP4 movies as you have in your patch. It ran without indcident. No crashes of Isadora, no crashes of the Background Movie Player. I am awaiting your answers to my questions in the ticket system and will proceed once I hear back from you.
I am a MAC user, so please pardon my negligence when it comes to windows playback. I am trying to wrap my head round rendering for Windows. I am trying to utilize HAP and HAPQ with Isadora on Windows 10, however, I am having an issue understanding how to render for Windows within MAC OS. I have read many forum regarding all sorts of ways to render on Windows with windows bases software, however, if there a software that will allow me to render, say HAP.avi on MAC OS?
I loaded Quicktime onto the windows computer, however, HAP.mov would not playback it only gave me static? I figured this was possibly due to the codec.
Does anyone have some advice on rendering Hap for playback on windows os?
We relooked at the situation and after running through a number of factors it’s clear it isn’t the mapping but more likely a corrupt video file. Re-outputting that and will get back to you if it is still occurring. Thanks much
I was using Shutter Encoder for Windows and was having problems with the HapQ.mov files it was creating. After installing the DNxHD codecs from Avid earlier today, I can now transcode DNxHR.mov to HapQ.mov using Adobe Media Encoder CS6. The files it creates run perfectly in version 2.6.1, so no more problem. Thank you for your suggestions.
Perfect. Mark had explained to me why additional buffering may help, so its great to hear that its working for you. I will do some testing in Isadora 3 with the same setup. I expect with some of the improvements that have been made that performance will be even better.
There was an issue with font rendering being changed by Apple causing a draw slowdown that could be scene in the scene editor as you mention. Mark made some changes to address it and I belive an new high sierra update also helped.
