Ideally you need a "normal" one, which means that its pick up is quite wide rather than narrow as the latter can sound odd if you are turning your head from side to side. Yes, a lav mic - known as a lavalier mic - is the same as a lapel mic, just a different name :- ) I'm already miking myself into the PA system of the room because I have voice problems but it doesn't seem like that would interfere. I suppose I could find an extension cable for a lav mic I think that means the same as a lapel mic. That's what I first envisioned but I'm afraid I would not restart the recording after the first half hour if I'm in the middle of a lecture. The lecture is quite good if you can cope with the poor sound quality and slide presentation. But Ms Glaunsinger has put on some nice makeup, and taken her glasses off. I found this so hard to listen to that I just downloaded the (main) paper (Glaunsinger is an author). The lecture has really bad sound quality, and only uses about half the display area for quite complicated slides. Lecture: " Coronavirus biology" - Britt Glaunsinger (HHMI,UCB). He has a good understanding of presentation, and of the technicalities of good audio and video. ![]() You can see some of the stuff he does these days at I think he has some understanding of your field too. Virology has been quite topical recently. Most of his career he's worked on Polio virus, but recently he recruited Amy Rosenfeld to run his lab, and he concentrates on science communication. Vincent Racaniello has had a lab at Columbia for nearly 40 years. Maybe I can record to the Mac, if that helps. I need to have high quality audio if this is to be available for students to access. I've thought about using the Macbook's webcam, sitting on a table say 10 ft away, but I anticipate audio problems. I need to capture at least from waist up. Then you sync the audio and video in post. Then you should have a separate recorder like a Zoom H1n or, if you are speaking into a mike for the venue's audio, like a Zoom H4n who you can just plug into the XLR output from the venue's mixer. Sitting on a table say 10 ft away, but I anticipate audio problems. A volunteer is cheaper and simpler than anything else. Or, you have someone monitor the camera, flag you when it's near 30 and re-start. ![]() You will of course need to be able to power the setup for 90 minutes. Is there any cheap camera that I can record myself lecturing with?Ĭheaper than a camera. I don't know anything about video cameras, etc. My DSLRs, I've learned, have a 30 minute limit for video, and my lectures go an hour and a half. But if you're familiar with dSLR's you may prefer that to any other option. But for your requirements you might just as well get a cheap lav microphone or other type of mic and wire it direct into your dSLR for much better quality than the native camera mic.Īny number of camcorders could do the same thing and you could even just use your mac with a lav mic or similar so that your voice is very close. Syncing can get tricky and you can use specialist software like Pluraleyes to do that for you lightning fast. You can use separate recorders and then match the video files with the audio files when editing afterwards. No audio will be great if the means of audio recording is more than a short distance from the speaker. This would also enable you to cut superfluous content and re-shoot any parts that are less than perfect. an MP4 format at a quality that is suitable for Youtube or whatever.Įditing software can run into the hundreds of $ but for your simple requirements you do not need such sophistication and the cost can be small or free. Why not simply record a series of say 3 clips of up to 30 minutes each using your dSLR and then bring the files into an editor and render it as one single file in e.g.
