    Hey there!

    I already saw some posts about recording a Resolume-output on Windows via Spout and I did a lot of research – but I really don’t get it, so I bring it up again, probably for the 100th time – sorry!

    My issue is the following:

    I got Resolume Avenue 6 on a Windows-based laptop. I’m a musician and completly new to visual/video stuff, so it took me a while to find out that Resolume doesn’t just spit out a video but is actually set up for live performance (the built-in recording function is actually not made for video-production, kind of confusing…)

    I want to record the output from Resolume to create a video for my music. I read that Syphon can do this, but only for Mac. Now I got Spout2 and I managed to see the Resolume-output on the reciever, but that’s all I can do for now. How can I record it?

    Some help/instruction would be really welcome here!! Thanks 🙂

    Unfortunately still, nobody has created a Spout movie export program equivalent to Syphon recorder.

    I understand that Resolume will create relatively short clips but is not designed for recording long movies. Spout might help you to connect with another program that does export longer sequences, such as Magic, Isadora or TouchDesigner.

    Or you can try screen capture solutions. Or use an HDMI capture card to record the display output on another computer.

    Alright, maybe I’ll see further into one of options you gave me, but still sounds kind of complicated! Thanks! 🙂

    Yes the capture card solution might not be the one for you. A low cost one could be Magic Music Visuals. The demo version could have the recording option you could try and should be quite straightforward.

    Edit : I just checked Magic and it’s not straightforward for Spout input! The help document explains that movies are not exported in real-time.

    I don’t have time right now to explore it, but I believe that OBS records video. The only Spout input is via webcam which will limit the resolution but you can use NDI output from Resolume into OBS.

    Otherwise you might try Fraps and see how that goes.

    Just now a program by Mathieu Jacques that could do the job for you. Give it a try.

    Hello,

    I have the same need as you.

    I tried http://spout.zeal.co/forums/topic/spout-recorder-3/ but it doesn’t export the alpha layer and produces stuttering videos in 4k.

    Does anybody have a solution which also export the alpha layer and that works in 4k at 60 fps?

    Thanks in advance

    Have a look at my reply to your other post regarding Spout to NDI (http://spout.zeal.co/forums/topic/spout-to-ndi-source-code/#post-4427)

    The NDI command line recorder works, but there is a bit of stuttering.

    Resolume CPU greatly increases when NDI output is enabled.

    Most probably because it has to encode in speedhq which performs compression and so on..

    Please correct me if I’m wrong, in order to record 4k 60h with alpha from a spout enabled app, it seems like the most efficient way is to consume textures like you do in Spout NDI, but instead of streaming them to NDI, saving them to disk “raw” and then encode it later. This is for video less than 60 seconds so disk space is not an issue.

    It’s a shame http://spout.zeal.co/forums/topic/spout-recorder-3/ doesn’t offer this feature and forces the use of ffmpeg “live”.

    Would you describe to me the shortest way (with examples or a few words) for me to develop an app that consumes the output of a spout sender and writes the raw data to disk? (Without using a spout receiver since in this case there is no need to use opengl).

    The recorder that Mathieu wrote does exactly that. Images are saved first and combined into a single file. The encoding is done afterwards.

    If you want to to bypass OpenGL , with some skill with DirectX I am sure it could be done. I couldn’t describe this in a few words, but have a look at the DirectX examples in the beta branch. Tutorial07 is the receiver. But I am not sure that this would save much time compared to the save to disc.
