Sofware for recording video conference, one file per participant

Question

I need a video conference app (free if possible) to do series of video conferences (interviews) and record it on the hard drive of the interviewer.

• The hard part: Each participant video feed/stream must be saved on separate files. This is for later video editing. For example, if it's a 1 on 1 conference, it should save 2 (or more) files: One for the interviewer and one for the interviewee.

• Audio files can be separatly or not. I don't mind meanwhile they are the proper audio streams of each video.

• MP4 compression would be nice, but not mandatory.

I already have tried Zoom but it does one single file of all the conference.

Windows is prefered. But I could run a Linux distro if the software meet my needs.

Answer 1

Janus Gateway supports capturing and saving individual audio and video streams at the server.

Janus is not a turn-key solution, it is a backend service requiring a web frontend.

I am unaware of any frontend that exposes the Janus stream saving features as a nice user-friendly web interface.
What exists are a few simpler video conferencing frontends, most notably Jangouts, and command-line based tools to convert stream dumps to standards-format media files.

Janus supports all common WebRTC video formats - both the proprietary X.264 and X.265, and free VP8 and VP9.

I've not used it, but it looks like Zencastr does separate recording for each participant. It also appears to record locally for each participant so supposedly you don't get as much drop-out due to network issues for your remote participants.
