Re: [Avid-L2] BUG REPORT - AMA audio import & transcode in projects with 35mm film options

 


Metadata, mostly. The new AMA iXML plugin allows for iXML metadata to be brought in along with the file. MC used to be blind for that chunk of any BWAV.
Also, Michael P has built MusID, a plugin that lets AMA-linked audio append id3 metadata. Meaning that it allows you to bring in music and library tracks with a whole lot of data automatically.

That said, AMA'd audio does not allow for Perf Slip, so end-of-story for most double system productions that prefer sync to be actually sync.

Hmmm, I though I would be doing that from Media Composer.  No?

So how would you control your monitoring volume?

You may want to shop for a 5.1 monitor controller:

Re: [Avid-L2] Monitoring Surround

 

Thanks,

I've been pouring over a lot of stuff tonight.  Looks like MOTU has one nice unit but they are all PCI so that won't work for me, but Matrox has one box with 6 discrete outs and another rack mount with 8 and both can use TBolt.  I've got active monitors so I don't want to deal with an amp in the way.  I'm not doing any input so the mixer just seemed like overkill.  The other benefit of going with the Matrox is that I get my video and audio monitoring in a single box so that should get it done.  I hope!

If you have active speakers, you may prefer a pre-amp with balanced outputs. I own a Denon professional preprocessor, A7100, that they no longer make, but the replacing mode lis the DN 500av.

This does not give you a mixer, but it does give you master room volume control. If you need a mixer, you need a BOB that gives you 5.1 i/o and a mixer with at least two stereo buses or 4 aux sends, om top of a stereo master output. I have my Yamaha 01V set up that way. Master L/R is L/R, Bus1/2 is C/Lfe, bus 3/4 is Ls/Rs (SMPTE order). Advantage is that any other sources (CD player, computer's internal audio card, etc.) can be hooked to any input of the 01V, and if i send them to the master output, they are played back over the L and R speaker.

Re: [Avid-L2] BUG REPORT - AMA audio import & transcode in projects with 35mm film options

 

Thanks for the correction. My question stands: what's the advantage to AMAing audio? I just spent the week bringing in a ton of multi-channel audio tracks and the imports were fast. If there's a bug to AMA'd audio, the cost of importing is minimal. I love AMAing video, but audio seems pointless for probably 90% of all applications and situations. But for the 10% who need it, I'm sure they're unhappy. If Avid claims to support this, then it needs to be fixed.

Not sure, but you might want to check with the Erwin Brothers production company in Birmingham... I don't have contact info.

[Avid-L2] Microphone audio recording

 

I am trying to record a scratch track with a headset mic. I can hear it in the speaker. I go to MC 6 capture I change the Audio setting I have 2 choices Firewire or Windows Audio Mixer.

This is anew Dell XPS8700. The audio in the computer is Realtek or Dellpromaxx.

The capture tool does not have that either choice and it does not see any audio. Has anyone had this problem? Can you add different setting to capture tool? I go to input an still only have firewire or Windows Audio Mixer.

Any ideas Thanks?

[Avid-L2] NYC equivalent of Digital Service Station? Output file to tape?

Hi:

I'm in the middle of restoring a film that suddenly has to show at MoMA a week from today. MoMA does not show files — they show DCPs or tapes. They say they show HD-CAM (and I am going to assume that they include SR in that because HD-CAM sucks!).

Since it won't quite be finished at that point, the filmmaker has decided that tape makes more sense — also, they can use these tapes when they license clips — so, here's my question:

Who in NYC can do a 90-minute output to HD-CAM from a ProRes HQ file, quickly and at a reasonable price? Anyone in Birmingham, AL (I'm near Montgomery)?

All suggestions appreciated.

Thanks,

Jeff

[Avid-L2] Monitoring Surround

 

Ok need a bit of a lesson here.

As I upgrade from MC5/MC6 to the newest version this week, I would like
to change my setup to go from monitoring in stereo to being able to
monitor and mix in 5.1 and 7.1. I am on an iMac. I am going to be
buying either a matrox or BM output box for monitoring my video. Can
someone give me a breakdown of what I will need to monitor multi-channel
audio? Computer interface? Mixer? Will my video output box get in the
way? Etc.

Thanks very much.

Re: [Avid-L2] BWF import problem, MC 7.0.4

 

I have not used perf projects, so I can't comment on whether your bug with those is any better in this version.

I'll admit my experience here does not cover many of the other people on this list's workflows - only adding my own in case it offers some relief…

Sorry, Mark, can you clarify -- was this in a project with the film options set for 35mm 4-perf?  Because having film options on is the crucial variable in seeing the CM_INVALID_TRIM error I mentioned.  I'd be very curious if you can reproduce it.

Cheers,

The AMA implementation for audio is VASTLY improved going from v6.x to v7.0.3. I haven't tested every scenario, but it has yet to let me down in what I've needed it for.

Hi Mark:

It looks like AMA-import and transcode of audio files is still problematic.

When I do this, I get a CM_INVALID_TRIM error when the transcode is complete, and the Avid wants to move a big chunk of the new audio files into quarantine. 

This appears to be the same bug I described at some length on this list in Feb 2013.  In my trouble-shooting at that time I found it only happened in projects with 'film options' enabled.  Kind of a drag to see still happening on a completely different system, on the latest version of Media Composer.  My system in 2013 was not fully in spec, but this current system is, so definitely a bug.

So the only good workaround for the BWF file import seems to be this:

  • Regular import of all BWF files as mono audio wav files.
  • Select the 5 monophonic clips for each group and autosequence them into a single sequence (all the clips should line up, since they all have the same timecode)
  • Auto-sync the new sequence to produce a single subclip with 5 tracks and the correct duration.

Cheers,
--Michael

Hi Mark & Job -- thanks for the feedback.

The most salient things that jump out at me from Michael Phillips' blog (on MC 7.0.3):
   -need to check the console for reports of timecode mismatch on AMA import (not flagged anywhere else.)
   -AMA includes more metadata fields than straight import.
   -AMA has no support for pullup/pulldown or 1/4 frame resync, even after consolidate/transcode.
   -workaround needed to get proper timecode from AMA clips into an audio EDL.
   -he says that monophonic groups aren't supported on 7.0.3, but that does appear to be working on 7.0.4 -- I'm getting 1 clip with 5 tracks via AMA import, rather than 5 mono files.

It sounds like the limitations of iXML/AMA Michael mentions are not likely to be a problem for me on this job, so if there are no horror stories I think I'll give it a whirl and see how it holds up.

Thanks,
--Michael

Haven't had any of the issues that Michael Phillips seems to have with AMA and audio in MC v7.0.3. I never bothered with AMA audio prior to this release, because of bad implementation, but it seems to be good for me in v7.0.3. I get good metadata and mono groups no problem.

Maybe OP can roll back to 7.0.3? I haven't bothered updating because of this and other egregious bugs popping up in 7.0.4.…
