Default AV Option or AV Option XL with Transoft Fibre

Is anyone out there succesfully using the AV Option (or AV Option/XL) with media playing back across a Transoft Fibrenet?

Default Re: AV Option or AV Option XL with Transoft Fibre

My main question has to do with workflow: I'm hoping to play both Audio and Video media (from an Avid Film Composer v7.2 project) using ProTools from the Transoft SAN. I know I need Film Frame software to deal with 24p media in ProTools, but besides that, can I truly receive a single OMF composition from the picture editor, convert it to PT using DigiTranslator, and open up a PT session with both video and audio playing back off the SAN?

My goal is to NOT copy either the Avid video or Avid audio media to local drives on the PT side, just create PT sessions locally that link to SAN-media. Since I've never worked with the AV Option before, I also have a more basic question: since my goal is to play back an edited reel of picture, can I assume that protools/digitranslator can play back an avid video track that points to many different masterclips/mediafiles or must it be 'rendered' into one long movie before I can use it?

Assume the picture is AVR9s and there are no more than 8 tracks of 48k/16bit audio.

Thanks in advance for the help,
-Phil

Hi Phil,

We haven't tried playing media on Unity in ProTools yet, but one potential 'gotcha' is that ProTools AV can only deal with one video track. On projects with visual fx or animation the picture editors would likely use multiple video tracks. That's why we are doing video mixdowns here at Pixar. The Avid function 'Collapse' might be a solution. I'll test it soon.

As an experiment, I did try copying the individual video media files over to my local drive (rather than doing a video mixdown), then opening the video track OMF in ProTools. It worked fine. Can't yet tell you if the latest beta will let you play media on the fibrenet.

Hope this helps.

SK:
I've been curious about this sort of setup too; can you tell us what kind of time it takes for the video mixdown (at what AVR resolution) for say a :20 A/B reel? This could be a selling point to picture assistants (who don't have enough time as it it!). Thanks for any info.

One thing to point out, Digitranslator does not deal with embedded video. In the workflow mentioned here, you most likely wouldn't be doing that any way. Just a heads up.

Pro Tools with AV Option does deal with multiple video clips but does not deal with multiple video tracks or unrendered video effects including video crossfades/dissolves. There are a couple of ways to deal with as already mentioned by someone. 1) Do a video mixdown to a single video track. Not always the best solution. 2) render all video effects. This is most likely the best way. 3) Export the video track as is. Pro Tools will leave video black in areas of the video track where unrendered video exists. This is sometimes OK to do when the rendered video will be coming in the future. The video track can be updated with a new OMF export. This way work can begin on portions of the sequence that contain single track video and/or rendered video clips.
