I just engineered a live concert and lives-stream that went really well.
The Murphy Beds folk duo have wonderful instrumental duos and vocal harmonies. They usually use a single Ear Trumpet Mic on stage, but for this concert I used my Soundfield DSF-1 decoded to a figure 8 pair at approximately 60deg separation. The single Bose stick PA speaker was off to the side (in the cancellation zone for fig pairs which prevented feedback issue). A small amount of a 3ft spaced pair of parallel MKH30 fig 8's about 30ft back and above the camera was mixed in to add some ambience (and audience singing). If I were tweaking this mix I would add more of the ambience mics. The audio was mixed on a Mackie1402 VLZ Pro and fed into the mic input of my Panasonic G85 . The HDMI camera output was sent to a Yolobox Pro video switcher/streamer to stream out (1080 30 at 8000 kb/s) via a strong WIFI connection to Youtube. No EQ, reverb or other effects were used. Even with the lossy compression of video live-streaming good mics make the difference for good sound.
The video will only be up for another 4-5 days, so do enjoy now. Comments welcome.

Nice work Bill (as always)!

Hope you're well!

Cheers,

Nice recording Bill. Is the DSF-1 feed split to to the PA and your mix for camera?

Great job ! Excellent musicians. The Soundfield works out fine. Something not about the audio, I am looking around to buy lenses for streaming. The shot you have what was the focal length you used? I plan to buy two cameras, probably Black Magics with a 12-40mm and a 40-150mm. Would that be sufficient to record an event like this?

Yes, for the mono PA I just used the Soundfield. For the stereo live-stream
I used the Soundfield plus a small amount of the MKH30's back in the room to add some ambience.

I am not very experienced with cameras but I use a Panasonic Leica DG Vario-Elmarit 12-60mm f/2.8-4 ASPH. POWER O.I.S. Lens, a definite step up in quality from the stock Panasonic 12-60 lens.
This lens works well for distances from 10-15 ft up to 30-40 ft.
Having a fast lens is definitely a must for the often meager lighting in restaurants and clubs, some concert venues and most churches. Having some lights is also a definite help to get good video, and especially when zooming in from a distance. With this video, which was done in a church with some overhead spots that were NOT aimed at the musicians, I depended on 4 Quasar Q-Lion 10 (12") lights (2 on each side approximately 10 ft from the performers. They will last a full 4 hrs on battery, have 3 color accurate temperatures and 5 brightness levels at each color. They have a 3/8-16 female thread on the end and 2 magnets on the back that make mounting easy. I also like the relatively low profile-2"x2"x12". For increased flexibility, I use a 3/8-16 ball-joint mount adapter on the end of the mic stand to allow more control over the angle of the lights.

If you have an iOS or android device you can download an app "Magic Cinema Camera" that gives you some great tools to answer this question. Simply tell the app what model BM camera you have and you can simulate what a lens with a selected focal length will yield.
I have both Canon and BlackMagic apps (free, with in-app purchases for advanced features) loaded on all of my devices. The first thing I do when selecting a camera position is to open the app and see lens(es) suitable for the task.

These viewfinder apps help you choose the right lenses depending on the camera and location you’ll be using. Also, you can take stills and videos with any camera/lens combo to do a proper location scouting report later.

Like Folkie’s kit in his opening post, this local youth orchestra livestream today also employed a Mackie 1402… and relatively minimal miking : omni SD’s for main pair (KM183), outriggers (OM-1) and double Bass spot (NT45 omni), plus a pair of cardioid SD woodwind spots (Lewitt 040 Match)

Hope you enjoy the Paganini Violin Concerto No.1 Op.6….maybe start viewing from about 13:00 ?

Cameras used were 5 relatively inexpensive Mevo PTZ’s:
