Audio Rending required when editing from a Sequence
on May 27, 2011 at 4:27:38 am

We are using the Sony Ex1 format material. Clips are imported via Sony XD Cam Browser which converts the MP4 video file to a mov.

To avoid having to search through the many imported clips we place all the Camera Clips on one timeline of a sequence - audio output reconfigured to 4 mono tracks.

This sequence is dragged across to the viewer and now acts as if we had "captured" all the clips in one action.

However if any more than one audio track from this Camera Clips Sequence is now inserted to the timeline for the Master Edit Sequence - (whose audio output is standard 2 track L & R Stereo), audio rending is required if there is another audio track on the time line at the same time, eg, music, nat sound effects or a blank part of a voice over track.

Does anyone have a solution to this problem please?

Open User Preferences and check how many channels you have in Real-Time Audio Mixing. If necessary adjust that number to meet you needs. Make sure your master sequence settings match those of your sources'.

The real-time audio tracks can be set as high as 99 tracks in FCP. Note that this number is more than just specific tracks on your timeline....it includes any audio filters you have placed on any tracks as well.

e.g.
if you have 4 audio tracks, and you set your real-time settings to 4 tracks, you will be ok. If, with these same settings, you add even one filter (i.e. compressor, EQ, etc) to a track, you would have to render, because final cut treats each filter like a whole other track.

So, make sure you set it high enough to include any audio filters in addition to actual audio tracks. I usually have mine at 16. Your mac should be able to handle that....especially if you have your audio quality (in the RT menu pop-up) set to either dynamic or low.



.....you could also render audio at the item level... instead of the default "mixdown". If you render one track with the mixdown, if you change another track that is at the same time in the sequence, you would have to re-render your mixdown.

Thanks Everest and Michael. Yes we do have suffieient Real Time Mixing tracks set up. Audio Rendering via the item only option does not assist the situation unfortunately.

The problem is editing from a 4 Track Mono Sequence to a Master 2 track stereo sequence.

The field material is recorded in 4 track audio as is most digital formats these days - XDCam, P2 and the Sony 500 using SxS cards which is the format we are using.

If only one audio track is inserted on the time line no problems with any other audio tracks in the same time frame. However if I bring down two tracks - say Audio 1 - (talent) and Audio 2 (reporter) from the four track mono camera clip raw footage sequence, audio rendering is required of the segnent that happens to overlap another clip on the timeline.

This problem does not occur if editing direcly from a camera clip, only when all the camera clips are placed in one sequence which has it's audio outputs set to 4 track mono in order to access any of the recorded field material. We cannot use a 2 track output sequence for this raw camea footage as then we cannot access any of the 4 original field audio tracks.

Am I hearing that it in FCP it is not possible to select tracks from a sequence in the Viewer and insert (or overwrite) these to the Timeline of a Sequence that does not have the same audio properties, without having to audio render any overlapping clips??

The problems you're having Raymond stem from your rather odd workflow, in which you chose to "nest" all of the 4-channel clips you threw together on the original timeline, which you're now re-editing. As you've discovered, nesting in FCP has numerous issues, and I would advise you that it is best avoided.

In addition to the issues you're facing with rendering, be aware that due to the nesting you will also find it difficult to match frames when editing, you may well find that recapturing frame accurate video may be difficult or impossible should you encounter a problem situation that requires it, and you may well have issues round-tripping to apps such as Color, STP, and Motion.

Furthermore, while dealing with clips rather than an entire roll of video tape may seem like a hassle, it's actually one of the tenets of non-linear editing. By placing all your clips on a timeline to create a single source, you're actually going backwards in time, turning your NLE into a linear editing device. There are many ways to skin a cat in FCP, but this one was not your best choice.

David I may not be very good at endeavouring to simply explain a complex problem.

I work in the world of daily news and current affairs and operate as cameraman/lightingman/soundman/editor, whereby one has to complete a field edit quickly after having shot the original material the same day and to deliver usually a compressed file via an ftp programe to get to air in the daily 6pm newscast.

One might record over 100 clips which the reporter has not had time to view til after the ingest from the SxS Card - via the Sony XD Cam Browser application.

Quickly dumping these clips down to the timeline, and then dragging that sequence across to the Viewer makes for rapid viewing of the field footage, compared to having to navigate in the browser thru what could be over 100 camera clips to view the field footage is a very slow alternative to zipping thru a "Raw Footage" sequence in the Viewer.

From this the reporter either notes time codes of the required shots for then editing down to a new sequence say called the Master Cut Track. If time permits the reporter may insert the required "Grabs" to a new sequence called "Grabs" inorder to assist in their thinking in scripting before the master edit begins.

The Master Cut Track currently has to be delivered to our station as a 2 track file ready to be played directly to air should that be required - Tk 1 Left = Main audio containing Voice Over and Talent, Tk 2 Right= Nat Sound Effects.

Normally field recording assigned camera tracks would be 1=talent audio (normally main radio mic internal receiver), 2=reporter's questions (2nd external radio mic ) 3= Nat sound Effects from Camera Mic 4= optional backup between camea mic or main radio mic.

If there is a quicker way to view and edit I am certainly open to other options by all means.

Raymond

Fair enough Raymond, yours is definitely a situation in which linear scanning and linear delivery do make sense. If you can shoot and import 2-channel audio only that might eliminate your need to render.

Thanks David,
I can see we need to discuss endeavouring to remember to switch back either Channel 1 or 2 back to the Camera Mic after using a 2 mic interview setup.
Cheers,

Raymond
