Re: [Avid-L2] Can't update video properties in QT7Pro when files is on a network drive?

Given the resulting file says "MPEG-2 Camcorder" does that mean that Shutter encoder has the -vTag set to "MPEG-2 Camcorder"?  Or could it be missing the -vTag completely.  The Media Info program sees it as XDCam50 in it's listing of metadata.

Exact the same video codec  but with another layout of sound will NOT be ‘XDcam’, although it miight contain EXACT the same data.

 

You CANNOT wrap MpegII / XDcam into a QT wrapper without telling the output what the file ‘should’ be, and expect ‘anyone’ to see what it is.

For that the  -vTag is needed.

Last time i’ve checked this will only give you the first two audio channels.

Getting FFmpeg to do more chabbeks will involve more typing work. Then, FFmpeg defaults to one audio track. Again, more work if you wantmultiple mono tracks. AND, the tracks higher than 2 will be flagged as muted.

 

(But QTchange can enable them again.)

 

For this kind of work a front end app is a good start, from there, if you have a fixed workflow,  write a bat or automator script, or have someone else do that for you.

I agree.  I've been using QT Ref just to get out of Avid and then do a save as because current Adobe Media Encoders no longer support QT Ref.  Unfortunately now I find that AME will no longer export a QT .mov with XDCam50 or any other XDCam flavor of codec.  It use to do that on my work system.  Perhaps I'm missing something in AME but I only see XDCam codec choices in the mxf op1a exports.  Fortunately I found that I can do a custom Avid QT export on my 10.12.6 Mac OS startup with MC 2018.12.12 and choose XDCam 50 24 422 in the QT custom settings.  Some new behavior to me was even though the QT Engine custom audio settings don't offer 12 channel discrete audio as a choice it turns out Avid in direct out audio format overrides the QT custom settings.  I got a prompt during export that said this and my resulting file did have 12 discrete mono tracks.  I was happily surprised to see the video levels in this workflow match the original sequence when I ama link to resulting file.  There is an ever so slight change on vectorscope and double diamond but I'm talking virtually no change.  It's much less than the old politically incorrect metric of the size of hair.  ;-)

Other than the suggestion of FCP7 I'm sure there must be other software that could take an Avid exported mxf op 1a file and create an XDCam50 .mov with 12 channels of audio but I've yet to hear one.  I would think FFMpeg could do this I'm just not a command line guy.  Perhaps the software front end FF Works would make it simpler to set up in FFMpeg if FFMpeg can do it.

To get around this bug, mount your drives under iSCSI.

Next, (and I don't want to go into all the issues, have other fish to fry), be VERY afraid of Perian.

For outputting a shitload of 'stems to stupid output', use my MXFtoMp4 for unattended fast rendering.

I share the sentiments about the loss of QTref.

Re: [Avid-L2] Can't update video properties in QT7Pro when files is on a network drive?

John,

Have you looked at alternate workflows that don't involve QuickTime Reference movies, QuickTime Pro, FCP7, Perian,  and XDCam 50 in a QuickTime wrapper?  

All of these things have been deprecated for years now.   Is there no MXF based workflow that fulfills your delivery requirements?  QuickTime (other than basic, straight up exports) is no longer capable of doing the things you want to make it do.  Apple has moved on and isn't going to fix it.

[Avid-L2] Can't update video properties in QT7Pro when files is on a network drive?

Re: [Avid-L2] How to Export XDCam50 HD 12Ch .mov Quicktime?

I did some testing today on my 10.12.6 startup drive with MC 2018.12.12.  If I do a quicktime export using custom I can choose XDCam50 24 in the QT Engine format settings.  Even though the audio settings don't offer 12 discrete channels as an option in the QT custom format audio settings with Avid in Direct Out it prompts that it overrides the QT custom audio settings.  I ended up with a .mov with 12 discrete mono audio channels.  It does come out with clean aperture on but I can turn that off with QT7Pro.  I checked the levels bringing it ama back into Avid and comparing to the original sequence and there is a microscopic change in level barely seen on the vectorscope and double diamond display.  Absolutely imperceptible to the eye and hardly to the scope.  Much less than things I've seen years ago.  I haven't checked my 10.13.6 startup to see if I still get those options running MC 2018.12.12. 

Here is another approach we got feedback on that has been used successfully:

You're right, this is kind of strange as xdcam is usually wrapped in mxf. We actually did this in a two-step process. We exported a normal xdcam50 out of Avid (direct-out audio), then re-wrapped it using Final Cut 7 (you heard that correctly). The great thing about FCP is that when the sequence setting is exactly the same as the codec, the export is only about 4 minutes. You just have to make sure you have an app like Perian installed so that FCP can read the xdcam natively. Then set up your timeline for the dub:

• Ensure your timeline start timecode matches the original XDCAM file.
• Audio - Config: Channel Grouped; 12 channel mono
• Ensure that your audio is patched correctly by right-clicking the area in the patch bay and ensuring every audio track is assigned.

Then do an old-fashioned sequence setting export (Don’t recompress/make self contained). There's one gotcha. FCP cannot export with a long file name (it will crash), so just export with a simple name like "304" and rename after export.

 

Note: It's up to how NBC handles their files, but we always rename and assign discrete QT audio channels inside of QT7. It's not always necessary, but we make sure the atoms are tidy in case their software is looking for audio assignment.

[Avid-L2] How to Export XDCam50 HD 12Ch .mov Quicktime?

I use to rely on my QTRef workflow to export a QTRef with 12 ch audio then take that into an older version of Adobe Media Encoder which still supported QTRef.  I could then export an XDCam50 QT .mov with 12 channels of audio.  At home I have newer versions of AME and they don't support any XDCam50 exports in QT .mov.  I can see them in the mxf op1A format but none in .mov.

Avid doesn't seem to like transcoding to XDCam50 so I'm told by my friend battling this issue.  He's got a new mac pro and an older system with a trashcan.  What would be the most efficient way to come out of Avid HD 23.976 timeline to end up with a 23.976 XDCam50 HD 12 discrete audio channel file?  He tried exporting an mxf op1A and bringing that into AME but it didn't like it and it doesn't seem to matter because AME doesn't allow an XDCam50 .mov export that we can find.

Why is this so challenging?  Or why am I being such a bone head not knowing how to do this.  We even checked Resolve but it doesn't seem to offer XDCam50 in QT container either.  What basic lay of the land has changed?  I know the newer MAC OS's have curtailed or eliminated the classic QT engine.  Is that at the root of this battle that use to work for me?
