Recording simultaneous video and recording

[NeuroLab]

Is recording synchronized video and audio possible?

Is there any example code for this? Or, please let me know how to do this 🙂

And please explain why is this related to LabVIEW?

If your camera supports it, yeah. Typically, you don't post such an open-ended question rather provide a short description of what is it you're trying to achieve, what hardware, what software etc.,

Use VLC.

Search VLC in this forum for examples.

Thank you for your reply. I study kinematics. I am using LabVIEW 2020 and a USB camera (acA1300-200um, Basler, USA) with a general laptop computer. The camera does not have a mic, but I wanted to add synchronized stereo audio to the recording video. However, I was having a hard time knowing where I need to start for that and decided to get some help from this website. I think that my explanation was missed in my previous question. Thanks for your comment. Have a nice day!

Feasibility depends on your definition of "synchronized audio".

1. Your camera does not have any way to connect an external mic which it can in turn record along with the video stream
2. Good thing, it has hardware trigger options
3. But your computer audio is software triggered
4. You can start recording your computer's mic or audio input but it will not be "synchronized" exactly with your video, possibly some millisecond delayed which is non-deterministic.
5. One option is just to start recording on the computer and in parallel send a software trigger to your camera to record video. Now, there will be a few milliseconds delay for the software trigger to be acknowledged by your camera.

You can use the Input palette to record audio.

Dear Santhosh,

I appreciate your kindful explanation with pictures.

Thank you very much.

Have a nice day!
