Add 'Record' input to Save Images to Movie

Hiya folks. There might be a good reason for this I’m missing…

I’m using the Save Images to Movie node. I assume this one is fairly popular.

However, I find it cumbersome to start and stop movie recording, currently doing it this way, which kiiinda works? (I’m seeing all kinds of audio sync issues, which may be something else)

Request: a ‘Record’ input which can be fired to commence recording.

(I’m seeing all kinds of audio sync issues, which may be something else)…

Have you tried adding a Select Input List (Boolean) for the audio, too, controlled by the same Boolean that controls video?

Keith,

We’ve discussed this with the team, and we feel that although a Record Input port could be valuable, we concluded that the potential value of a Record Input port would be outweighed by the additional complexity / reduced usability. We’ve consistently tried to avoid having input ports that can make other input ports stop functioning (e.g. Save Video Frame only works if Record is true). Select Input with a Toggle Action Button would give you a direct way to control the node’s behavior.

We’ve investigated the audio issue. For Save Frames to Movie and Save Images to Movie, when starting the audio and video after a pause, the audio and video become out-of-sync. We’ll create a bug report.  

Thanks Jean Marie — I understand the aim for simplicity.
This is how I’m managing starting and stopping. Is this is optimal way?

It depends on your aim. What you are doing makes sense to me. To output the audio without the transformation from channels to mixed samples you could use Select List instead.

If you want to pause and resume the recording after audio-video sync is corrected, then you’ll need a separate way to finalize the movie.

Thanks. Any and all optimisations are appreciated!
