Michael, apparently the previous AMA issue did not work. My tech tells me we are on v. 5.5. Here’s what happened when we edited the text file.
Okay the ALE will still not link with the AMA media, but now I’m getting a different message at least (and this could ultimately be related to the other issue)

Now when I try to merge the ALE with the AMA file I get the message:

‘Exception: Expected sourceMob edit rate does not match the actual edit rate on the sourceMob’

The ALE and Avid project are 23.976 … QT reports the .mov as 23.97 … when I AMA the QT file into Avid and put it on a timeline Avid reports it as 23.96

I have tried editing the ALE to be 23.97 and 23.96 and both give me the same error message.

As noted before I am also getting a Timecode discrepancy when I AMA the file … while in Final Cut and Quick Time the punch is at 1:00:00:00 the punch on the AMA is reporting 00:59:59:22 (or on some files 21) …. I can modify the timecode in Avid to line the timecode up at the punch, but it drifts out if I put it on a timeline – that is to say if I look at the timeline TC and the AMA TC they both start at 1:00:00:00 but several minutes down the timeline the timeline will be (note numbers are rough examples not specific instances) 1:04:00:00 and the AMA TC will show 1:03:59:22 … further down it may even be Timeline 1:06:00:00 AMA 1:05:59:23 (again these are not numbers I’m pulling from avid so it isn’t nessicarily a 1 frame per 2 minute drift I’m just illustrating the issue.)

The same quicktime file on a 23.976 timeline in Final Cut the timecode tracks frame for frame as would be expected.

As I haven’t tried other media via AMA I don’t know if that is just normal behavior (which I would doubt as it would cause problems matching back to the material as needed) … if it’s because it is ProRes 4444 material (more likely) … or if it’s another issue entirely (the answer I expect).

Thanks, Film Joe

Michael,

Thanks for your feedback. I have another complex audio problem on a studio feature that you might have some solutions for that no one else tried to answer.

1. I have a PlayBack music track and a dialogue track to sync to a digital shoot. The dialogue starts and half way into the take the PB track starts. When I sync them in the time line, I cannot make a subclip since there is no audio at the head of that PB track. Any way to solve this?

2. I did a telecine transfer with some PB tracks to HD tape so I get the TC burn in for the editor. But I have other takes on that tape that have dialogue only so it’s faster to sync that manually after I digitize. But after I sync the dialogue only tracks, and make subclips for those, and make subclips on the takes with PB, the audio TC metadata is missing in this new bin. If I post-sync in Avid the whole tape, there is no problem, but is some clips that were digitized have audio, then it can not match TC on the other takes that I post-synced audio. Why would the bin data care when making a subclip bin if there was some audio digitized in the master clip?

We’re always trying things that are outside the norm. Thanks for any ideas you might have.

Thanks, Film Joe

Thanks Michael,

Does Sorensen work with the Matrox Max accelerator though? Compressor can add a watermark from a FCP file, but not Avid mxf media. I take it Sorensen has no problem coming from Avid mxf? Our techs don’t use Sorensen, but it comes with MC right?

Thanks, Film Joe

Mark, to clarify- The problem here isn’t the QT Reference … I can open and play it fine. But once I go into compressor and make an H.264 from that reference file all I have is a dark image of the first frame with the title burn. Checking “network references” does not seem to affect it.

Do your tests confirm this? Would Sorensen of some other software from Avid third parties fix this? Let me know if you have any ideas.

Thanks, Film Joe

Mark,

Not sure that works. If we have Avid mxf media and render a QT ref movie, Compressor can not add the super. Every frame comes out black with the super. (in FCP a QT ref movie does work, but not from Avid media). Is there a setting I can change to correct this?

Thanks, Film Joe

[Joe Huggins]

thanks, this cleared up some confusions. Joe

Thanks, Film Joe

[Joe Huggins]

Thanks. You confirmed my understanding and we have found how to show multiple TC windows. The editor needed the PB TC displayed to confirm his sync points musically. I’m not sure what his final output will be but your ideas were most helpful.

Thanks, Film Joe

Glen and Gary,

First, Sorrenson can not handle the quality required. We need 2400kb and it’s top is 1800. Also we need to set for ‘fast start’ and there is no option for that in Sorrenson. I guess Compressor is the only choice? I would think Avid has some better third party options?

The Black Magic box could be good, but no specs on that as it is not in production yet.

Any other ideas?

Thanks, Film Joe

[Joe Huggins]

Thanks Glen. Our team will check, they thought Sorrenson was PC only, so it does work on Macs and we might have overlooked this Avid to QT ref, to watermark in one step process.

I’ll let you know for sure tomorrow. I knew there had to be a better way.

Thanks, Film Joe

Thanks, Michael,

The second subclip would then keep that take merged with the new iso in case it was used in another cut, but not necessarily a second step as you point out.

Yes, got you and Tom mixed up a bit, but remember your work.

Regards

Thanks, Film Joe
