Workflow - V|10, PT7.1, LANshare, OMF & AAF
Greetings all!
Digi dealer phone support was a bit vague on this, so I thought I would pick your brains. Broadcast Facility, on a LANshare...so PT automatically cannot use it in real time. It will have to be push-pull. Meaning, Export the files, manually copy them to local storage, then access them. XW8200, 2 SCSI drives (non striped), V|10, Media Station 1.8.2, PT 7.1cs1, 192 I/O, Sync I/0. Client also has some Adrenalines as well. So the workflow would be to edit on the Adrenaline, then export for use within PT. OMF limitations limit you to 2GB. I believe AAF does the same within the PT environment. That's no good for the clients requested 2:1 compression (about 35 GB/hr). Digi tells me that within Adrenaline MC, I need to export: 1 AAF, with embeded Audio. 1 AAF, where I consolidate and Link Source Media. (I presume this creates a new media file...movie file...that is only the clips in the sequence) I then import these 2 files and BOOM, everything is good. My questions: Isn't there a 1 step way to do this? Or is it negated because they are on a LANshare? Wouldn't I run into a file size limitation with the AAF Video export? What better way is there to do this....and howabout the reverse incase they want to get the sessions back into Avid? Thanks!

Re: Workflow - V|10, PT7.1, LANshare, OMF & AAF
It's actually easier than that... they only need to do one export. On the Avid side, have the Avid editor(s) consolidate their sequences (audio and video) and then do an AAF (or OMF) export with linked audio and linked video. Make sure the AAF (or OMF) export is made from the consolidated sequence. They will also need to render any video effects in the sequence before exporting. Preferrably, the Avid consolidation should be done to a dedicated Lanshare workspace (or other drive or partition) for Pro Tools transers for file management purposes but is not required. The export will create a tiny AAF (or OMF) file that is simply a pointer to the consolidated audio and video files. Copy the small AAF (or OMF) file and all of the audio and video to appropriate local drives on the Pro Tools system. Then, either use "Open Session" and open the AAF (or OMF) file OR use "Import Session Data" or drag and drop the AAF (or OMF) file from the Pro Tools Workspace browser into an existing session. That's it. They should have the entire seqeunce (audio and video) in Pro Tools. Since they have the V10 hardware on the Pro Tools system they don't need to worry about video resolutions, the V10 will be able to deal with any Standard Definition video the Avid spits out. To get back to the Avid from Pro Tools. You can export from Pro Tools on a per file, per track or bounce to disk basis. - Per file. Select the file in the timeline or in the region bin of Pro Tools. Choose "Export selected as file" from the region bin menu in Pro Tools. Make sure you select "Avid Compatibility" when selecting the destination and file type. .WAV or AIFF is fine for Mac or PC Avids, the sample rate and bit depth is up to you and your workflow (typically 48k, 16bit although Adrenalines are 24 bit capable). On the Avid, put this Pro Tools exported file into the "OMFI MediaFiles" folder or "Avid MediaFiles" folder depending on the Avid prefs. Then use the "Media Tool" in the Avid to locate the file and drag it into an avid bin. It will have the timestamp from Pro Tools and can be spotted into the Avid timeline based on the timestamp. - Per Track. Select the tracks you want to export from Pro Tools. From the file menu in Pro Tools 7.x, choose "Export" and then "Selected tracks as OMF/AAF...". This will create new media for every audio file on the selected tracks. Selecting the video track with this method is not possible (the Avid should already have the video sequence anyway). This will not include any automation or TDM or RTAS plug-in processing on the selected tracks. - Bounce to Disk. This is the most typical method. Once the Pro Tools sweetening and mixing is complete, choose "Bounce to Disk" (the new keyboard short cut is Option - Command - B.) Be sure to select "Avid Compatibility" while selecting the destination and sample rate/bit depth. Put this bounced file ( a stereo or surround mix) into the "OMFI Mediafiles" or "Avid Mediafiles" folder of the Avid and use "Media Tool" in the Avid to drag and drop the file(s) which should appear as a single master clip into an Avid bin. It will be timestamped from Pro Tools with it's correct timeline location. Hope this helps, Jon Connolly Digidesign Product Specialist |

Re: Workflow - V|10, PT7.1, LANshare, OMF & AAF
Excellent! I needed this info so badly.
You mentioned "Copy the small AAF (or OMF) file and all of the audio and video to appropriate local drives on the Pro Tools system." ALL of the Audio and video is...? If I consolidate, then a new movie file is created, so there is only ONE file for video...what about audio? Or, do I just copy the entire OMFI media folder over? I can see where that would cause a problem is the pix editor doesnt do spring cleaning...HUGE OMFI media folders with data that doesn't even pertain the the project going over to PT! Also, on a side note, what region do you cover...I think I may have heard your name around the area. Please email me off list if you don't mind. michael at lucidsound.com and/or mkammes at mwmg.com Thanks Jon!

Re: Workflow - V|10, PT7.1, LANshare, OMF & AAF
Consolidate on the Avid is different than consolidate in Pro Tools. In Pro Tools, consolidating several files will create a new single file containing all of the data of the orginal selected files. Consolidating in an Avid is creating a new file (audio and/or video) only of the size that is being used in the sequence. For example, if you digitize 30 seconds of video but only use a small portion, five seconds lets say, of that clip in your sequence/timeline. Consolidating that sequence will create a new video clip five seconds long (plus handles, your pref. here but I think it defaults to 30 frames or one second) so that you don't have to deal with the entire 30 second original video clip when copying, archiving or whatever... Consolidating on the Avid will NOT take several video clips in an Avid sequence and turn them into a single video clip, that's a different process called "Video Mixdown", which you can do if you'd like but is not necessary for the workflow you described. If you just consolidate the sequence and bring over all of the individual media files (audio and video), you will get the video edits in the Pro Tools video track which can be very useful. If you do a "Video Mixdown" in the Avid, the Avid editor is adding a few steps to their export process because they then have to do the Video mixdown, spot the video mixdown file into the sequence and then consolidate the audio and then do the AAF/OMF export. AND, you'll end up with a single continuous video file in Pro Tools with no edits. Individual video files and a Video Mixdown both have their advantages and disadvantages but if this Pro Tools system is on Unity then it's probably more beneficial to not do a video mixdown. > , do I just copy the entire OMFI media folder over? I can see where that would cause a problem is the pix editor doesnt do spring cleaning...HUGE OMFI media folders with data that doesn't even pertain the the project going over to PT! Exactly, you probably don't want to do that for that very reason, that's why I suggested using a dedicated transfer volume, drive or Unity/Lanshare workspace. This way the Pro Tools mixer can delete (or manage) the files on the transfer drive without affecting the Avid. >Also, on a side note, what region do you cover...I think I may have heard your name around the area. I'm in Los Angeles but I was in Digi Tech Support on the phone for a few years, a few years back, so I dealt with different people all over, not to mention my babbling here on the DUC.

Re: Workflow - V|10, PT7.1, LANshare, OMF & AAF
Thanks again for the reply!
While working on this today, I think I stumbled upon an even simpler solution: Per your instructions: If you do a "Video Mixdown" in the Avid, ... spot the video mixdown file into the sequence and then consolidate the audio and then do the AAF/OMF export. AND, you'll end up with a single continuous video file in Pro Tools with no edits. Thats great. No Huge OMFI Media Files Folder. Then, export (SEND TO Pro Tools) COnsolidate and link to audio and video. Let Avid to it's thing. Save the above AAF files to the shared workspace on the LANshare. On your PT rig, Open PT and Import Session Data. Find the original AAF file, and when the screen pops up asking for what tracks to put them on, (i.e. various import options), change the prefs to "COPY MEDIA" instead of linking or referencing it. All data (Audio and Video) are then copied to your local storage. No need to shuttle around huge OMFI media folders! Simple, but elegant. Thanks again!

Re: Workflow - Avid & Pro Tools
I'm again in a situation where the workflow between Avid and Pro Tools is a bit more difficult that what the editors would like, so I thought I'd rehash this (relatively) old thread to see if anyone else had more input.
This time, the client has PC based Adrenalines, and PT 7.1 on a Mac with a Mojo, no shared storage. I would think Avid/Digi would have a SendTo that worked in one step, but I am unable to do so - at least until Pro Tools supports embedded Video in OMF and AAF. So, is it still exporting the audio as an OMF, and then Exporting (or Send To) the video? In the PC version of Adrenaline, there are 2 dozen presets under export..any thoughts?

Re: Workflow - V|10, PT7.1, LANshare, OMF & AAF
Hi
I work in Holland for a Post Production Company with one site consisting of Unity shared storage and an other site with Lanshare, both have a Protools System running! However Lanshare isn't supported officially I work on the Lanshare and It works great, no push and pull. Playback of video 2:1 or 20:1 mixdowned or a rendered seqeunce and Audio is also comming from a dedicated Lanshare workspace! Our workflow consist of an OMF file linked to video and linked to audio. And with Import Session data we consolidate the audio to the dedicated Protools Workspace with 2000ms handles and we link to video! It works great! Greetings David Klooker Avi-Drome |

Re: Workflow - V|10, PT7.1, LANshare, OMF & AAF
Excellent!
In an environment without a LanShare (i.e. just networked storage) then OMF woud not work (as linking would not work), so, is there another workflow you would recommend? Thanks!
