Very funny. It's all fun and games until a take sounds like Darth Vader.
I am prepping a show with 13 or 14 RF mics from a rental company with a mix
of 411's and 211's with lavs and a RF hand held. The 24 input Midas mixer
will not have delays.
I have asked Lectro for a mic power supply or preamp with this feature. Any
delay will have to pass phantom anyway. If Lectro doesn't step up, how about
Remote Audio, SD, or PSC?
Now to vent. Delays in the video world. The following is what video
facilities have to put up with. This from an actual email to editors.
Here are the findings on audio delay through the HD Production Equipment.
From VC-13 to ANY ANALOG deck, the audio is delayed by 1 frame in reference
to the video. That means, composite video and analog audio are out of sync
by 1 frame. Video leading audio.
All VIDEO through the HD switcher that is downconverted to analog is delayed
by 4 frames. The settings on the Rane audio delays therefore should remain
at 4 frames.
There is no delay on the switcher downconverted DIGITAL signal, it's already
embedded at that point, so it stays in sync.
Video through the upconverter is delayed by 2 frames. The Rane delay unit
for the upconverter is in the audio room, however the audio operator patches
it to his monitors to eliminate intercom delay in the audio control room. We
should install one in the on-line room to handle upconverting needs.
Video through the DVE is also delayed by 1 frame.
So, playing back an SP or Digi beta tape in VC-13 then blown up through the
DVE and recorded to any digital deck will need a 1 frame audio delay to stay
in sync.
In a nutshell, with the current Rane setting of 4 frames, all audio paths
are in sync.
The only paths to watch out for are these.
From VC-13 to any composite input (Audio delayed 1 frame)
Video through DVE delayed by 1 frame.
Video through the upconverter, delayed by 2 frames.
Please let me know if you notice any lipsync problems from this point on.
