Our university has forced us to use a compiled executable Zoom application downloaded from the university (and available for MS Win, Mac OS X, and DEB for Ubuntu or RPM for EL). The user interface is very poor. My wife recorded her class to the University-designated cloud, and I am not downloading the MP4. Unfortunately, because of the poorly implemented user interface, there was no indication that the audio recording was not working. As a result, she has the video but no audio. Is there a method to run the video and at the same time (with minimal latency) record into the audio track of the MP4 as the video is playing? That way she will not have to "re-record" her lecture, but simply supply the missing verbal content. Any application for Linux would be appreciated; in a worse case, a MS Win one will suffice. We do not have a Mac OS X machine. Please do not reply solely to this list and my university email. My private email -- much more reliable -- is [email protected] . Yasha Karant
