Re: [Avid-L2] Help for audio files quarantined with CM_INVALID_TRIM error

 

Hi Rob:

Given that AMA+transcode is typically many times faster than
File+Import, you could argue that Avid is pushing editors down the AMA
route through their software design, and deprecating traditional import.

I guess my expectation of AMA is that if I can link to a file and play
it back, then I ought to be able to edit with it without problems.

If you have a link to documentation on the requirements and limitations
for AMA I'd sure like to read up on it. I've never seen anything from
Avid suggesting AMA shouldn't be used with audio sources, for instance.

Regards,
--Michael

Re: [Avid-L2] Help for audio files quarantined with CM_INVALID_TRIM error

 

Hi Job:

I tried using AMA to bring in BWAV files for 2 reasons:

1. I've never seen anything in Avid documentation to suggest this
workflow is unsupported. I see nothing in the Symphony help files, for
instance, and Avid's document "Avid Editing Systems - Supported Formats"
makes no reference to audio formats at all. Avid will link to BWAVs
(and other audio formats) via AMA without complaint -- so why should I
have anticipated a problem?

2. What the Symphony v.6 docs do state is this:
"You should not mix workflows. Either use the AMA method or use
the traditional import/batch import method."
This implies that it's a bad idea to use AMA to bring in video clips
while using traditional import for audio. This is why I tried using AMA
for my audio initially (and quickly gave up on the idea when I saw the
timecode did not come in properly for BWAVs via AMA.)

You may not think this is a bug, but perhaps you would agree the docs
are obscure, if not outright misleading. If this workflow is
unsupported, as it appears to be, then don't you think that should be
made obvious? I'd like to see a warning dialogue when using AMA to link
to unsupported formats.

When I was searching for an answer to why I was getting these
CM_INVALID_TRIM errors and quarantined audio files I found others asking
about the same problem, but no answers for why it might be happening,
which is why I've posted my results at some length.

In that vein, it might be worth noting that this error is not
limited to .wav files -- I had the same problem with .mp3 files which
were AMA'd and transcoded in a project with 'film options' enabled.

Regards,
--Michael

[Avid-L2] Re: Help for audio files quarantined with CM_INVALID_TRIM error

 

In tests I did a while back there was a Resolve setting having to do with maintaining reel names and other metadata necessary for later relinking in Avid after a round trip. I haven't played with it in a while but I'm sure somebody will know the exact settings to make sure are set. Not sure if that will solve your issue but the inability to relink might be related to those setting(s).

[Avid-L2] MacPro Firewire Buss(es) and transcoding errors?

 

As I am transcoding to DNX 45 from DNX 220 I am getting errors when I try to transcode directly from a 4TB self powered GRaid hooked up to the rear FW 800 connector and FW 800/400 cable hooked up to the other rear FW 800 port and a nexstar -3 external enclosure self powered with a 1TB drive.  The DNX 220 media is on the GRaid and the DNX 45 is going on the nexstar.  I forget the exact error but it stalls at various times with one or more clips in a bin transcoded.  I had a real issue with an hour plus clip and after several tries opted to transcode to the internal raid not the nexstar enclosure which is FW 400.  This worked even though I found an error the next morning the clip actually did transode to the internal raid.  I tried again to day to go direct with a bin full of shorter clips and it errored out after the first clip.  Back to the internal raid and life is good.  I googled and it seems at least for 2006-2008 MacPros there is only one
firewire buss shared with all the ports front and back.  I assume this is still the case but I can't find any info directly addressing this.  Can anyone confirm or deny there is only one firewire buss on a MacPro?  Even if it is only one buss I feel like this shouldn't be an issue to do this transcode from one drive to another on my brand spanking new 12 core MacPro.  The project is running from the desktop so that's not taking up any firewire bandwidth.  Am I mistaken to expect that to work.  Sure seems strange to get something mentioning a codec error when attempting this.

I think it's also an add-on board for Nitris DX, not sure if that comes with the badge.

Sorry, no. But I have been thinking of doing that exact same set

[Avid-L2] Keyspan Adapter for USA-28X B?

 

I've gone to the Tripplite keyspan site to find driver's for my USA-28X B but I can only find the USA-28 XG.  My recollection is the "B" vs. "G" was because the G was ROHS compliant.  Given I can't find the "B" driver I'm going to try the "G" driver.  Can anybody share any experience in this regard.  I don't have a deck handy to check things with right now but will have a deck brought in in the near future so I'm trying to prepare ahead of time.  TIA  Also I recall people had complained that the ROHS compliant Keyspans weren't frame accurate like the older ones.  I've never had a chance to A B or in this case "B G" compare head to head but I've definitely had frame accuracy with the G units using Nitris DX hardware.  On the other hand firewire Mojo SDI's were inconsistent in frame accuracy with Sony digibetas but dead on with Panny DVCPro decks.  Anybody have any tests they've done with Keyspans and frame accuracy?

[Avid-L2] Re: Isis workspaces

 

So it's really AVC Intra and that makes sense with the option board you mentioned at one point in the thread Steve. So even though it AVC Intra, Steve you mentioned it felt very sluggish which led you to believe it was a long GOP format. This sounds like even though it's a valid Avid Codec it's performance might be less than an Avid DNX codec. At least that's what you are describing from you experience on the system. I wouldn't be surprised that even though it's now an Avid "Native Codec" it doesn't work as well as Avid's DNX. At that point I guess it's use would have to be weighed with the ease/speed of ingest from the field cameras verses whatever deleterious performance the editors face. I'm guessing greater more knowledgeable folks have made those assessments already and as always stuck it to the editors. ;-) Of course I've also seen repeatedly cases where production decisions have dictated the post workflow even when there were more efficient approaches available but alas Post is always the last to know.
