Re: [Avid-L2] Re: Resolve on Symphony

Thanks Oliver. I've used SpeeGrade in the past (when it was from Iridas),
honestly I prefer symphony over speedgrade, I mainly do TV Color
Correction, I'm interested in Resolve because seems that is going to be the
De Facto tool for CC and nodes is something I like and the workflow for
Avid seems good if working in DNxHD.

Re: [Avid-L2] Export Help needed really BAD!

If you are exporting over a network connection or to a FAT32 formatted drive, you might be running into a file size limit problem (under 4GB), but the reference version should not have that problem.

Have you pre-rendered? It sounds like you have corruption at the 1hr (export time) point, which will likely be somewhere between 30 mins and 1hr sequence time. Try rendering that section in pieces. When you get an error, look for complexity of any type. Any very large graphic image (3000pixels or larger) is a likely problem point for a rendering.

If you have prerendered everything, this is not the problem.

Cheers,

[Avid-L2] MC/Sym 6 desktop image display is sub-par

 

[Rant on]

I tend to work a lot on systems without externally connected monitors. I've also worked in broadcast bays, where the connected video monitor is about as bad as one can imagine. It's time that Avid comes up with a UI overlay that works for this century. The following applies to Mac as I haven't tested the same on Windows versions.

1. Images displayed are not adjusted for monitor color space and look washed out.
2. Images display noticeable tearing during playback. This is a refresh/sync issue, which was briefly fixed in MC5 and then broke again in MC6.
3. The full screen display shows tearing and does not show an expanded luma range. Again, this was broken with MC6.

The exact same system will properly display images without these issues on other applications - FCP7, FCPX, PPro, Resolve, SpeedGrade, Color, etc.

Issues like these make using Avid software a less-than-pleasant experience.

Correct. Resolve uses a second GPU card (CUDA preferred) to offload some of the processing. This is intended to maintain real-time performance in an output-to-tape situation. I've run tests using 1) only an ATI 5870, 2) only a Quadro 4000 and 3) a GT120 + a Quadro 4000. I got very little difference in performance. With only a couple of basic nodes, the dual-card combo gave 2-3fps better performance. Both close to 24fps. With a lot of complex nodes on back-to-back clips, I had a few frames more playback performance with the dual-card set-up, but none of the combos was real-time.

FWIW - Resolve Lite is free and runs with BMD capture cards (only), but if you also have CS6, make sure to check into SpeedGrade (included). For now, you are stuck with only using a desktop display, but performance is faster and stays real-time longer. Layer-based, rather than node-based. Similar results. No MXF workflow, yet.

Re: [Avid-L2] Export Help needed really BAD!

 

Remain calm.
Copy sequence. Separate sequence into at least four 'acts.' Do a video mixdown to an avid codec of each act. Replace video with
Mixdown. Do a similar stereo audio mixdown of each act.

Actually, only mixdown The first 'act' at first, to make sure this works. (You probably have a corrupt render somewhere.)

I assume you're trying to send the movie to a compressor or sorrel son or something, so now just use QT reference- and you should be good to go.

I'm betting that the video mixdown will run into a problem.... Maybe somewhere in 'act 2' ?... If that's the case, use the 'divide and conquer' which should be assistant editor 101- keep attempting to mix down smaller an smaller 'halfs' until you isolate the corrupt media. E
Probably will just have to force and effect to re-render.

Another way you can sometimes find corrupt media is to exit the program delete the media files database then allow the media composer to rebuild them on restart- it will sometimes quarantine the bad media. Not always, though.

Good luck! Chin up!

Re: [Avid-L2] Export Help needed really BAD!

Do you get any error messages? If so, what are they?

It's 4 hours long, all in one sequence? Does breaking it into sections allow export?

Are you mixing formats or have any AMA'd files?

Here's one thought (and I'm sure other on the list will have others):
Select the entire sequence and all the video tracks, then perform a Video Mixdown (Special menu).
You'll edit the resulting file onto a new video track.
Then when you go to export, make that the only active video track (and be sure to activate all your audio tracks too).
In the export settings, enable the selection about using only "active tracks."

^^ Before you do the whole show, test this with a small portion and see if it allows the export.

HTH...
Cheers,

B

I'd like to hear more about the round-tripping working well. I have not found that to be the case. Perhaps it's because we have mixed codecs, but what's your config and workflow?

My cunning plan was to hopefully use a USB 3 to HD SDI black magic box for monitoring, as I don't want to give up the Universal mastering on Symphony. With a Media Composer this has worked very well round tripping- with Resolve reading and writing to the MXF folder.

Has any one tried this with Symphony?

I suggest:

Well, if there's only one clip of each audio and video, as a test,
you could 'divide' them by using 'add edit' to split them into two
clips, make two separate sequences out of the two pieces, and then try
exporting each sequence separately. If one sequence works and the
other one doesn't, you've narrowed down the location of the damage.
But it sounds to me like that won't help you either. I'm still pretty
sure that you have one or more seriously corrupted clips that's
causing the problem. I've seen this issue at my workplace as well,
though I am not in a position at NBC to fix the problem (or even fully
understanding it). We have the luxury of simply abandoning the
corrupted clip and either using another similar one, or skipping it
altogether.
If it's only a single clip of each audio and video, can you simply re-
capture the original clips and try to export again? If the clip(s)
are damaged as I suspect, re-capturing might give you undamaged media
which should export OK.

Artisinal also said:

> As I described in my original post, even after mixing down, I still
had to take 5 or 6 tries before I stumbled into the loop where it was
"scanning for unrendered Audio Suite plugins" which hung up for a long
moment. When I then cancelled out of that dialogue, for some reason I
was now able to make a single export. After that point, further
attempts to export resulted in the same "Movie Export Failed" error.

I say:

This clue leads me to believe that the damaged media is an audio
file. Your Avid is having trouble mixing down the audio. The
corruption is causing the hangup; cancelling out may produce an audio
mixdown that's not complete, but enough to make your one export.
After that, attempts to export the mixdown produces the "Movie Export
Failed" error because the corruption is still present in the mixdown.

Artisinal continued:

> Also, I was able to reproduce the other error message. It was:
> Exception: std::exception, what: "Segmentation fault" in thread
"Adopted Thread", at address 0x0
> Does that help shine any light on things?

I offer:

Not sure but it could be that the clip is unreadable at the very
beginning. I think a segmentation fault refers to the 'joints'
between segments in the media. A clip in a bin may actually point to
more than one actual media file. Joints between these files may not
match up, causing a segmentation fault. This is a guess, since I
don't really know the underpinnings of Avid media.

Artisinal closed with:

> Thanks for any help anyone can give. 3am is not a fun time to find
out you can't get your video out of the computer.

I say:

I know what you mean. Unfortunately, 3am is when I START to
