Hey all, got a small problem here. Took some recent Epic 5K HD footage into RedCineX and I've noticed when I play back the r3d I hear the audio recorded in camera in the player in RedCineX. However, when I go to export it as a pro res quicktime, even with the audio boxes all checked, the quicktime has no sound with it. I'm using the latest version of RedCineX and the Epic is on the latest build. Any ideas or help would be appreciated. Thanks!
 
Hi David, yes I did that as well. What's odd is I just exported the same clip just now, and it had audio and the only thing I changed in the rendering setup was I went from 1/2 premium debayer to full debayer. Odd, but it's working now.
 
I'm having the same problem only worse now. I exported a QT prores 422 file and it had no audio. Tried it again and the file never materializes after the export. Says it's there, but it's not. So I went from having a file with no audio, to a file that isn't there. Have tried it on older footage and getting the same result.

Need a little help, please.
 
OK, something is definitely wrong with this version of Redcine-X with my setup. When I try to export a clip from the viewfinder, it refuses to place the clip in the designated folder. On top of that, it adds the folder name to the name of the file and places it outside the folder, directly on the RAID. Never seen this before, very odd behavior.
 
Hi Mark,

Thats a known bug with Build 15 unfortunately. As for the audio problem, have you configured your QuickTime audio settings?

David
 
David,

Yes, and typically the upgrades keep the configurations I've already made. I just went back to 14 and everything is working fine. I'll stay there for the time being. Thanks!
 
Hi Mark,

I understand .. the upgrade to build 15 added a new configuration for QuickTime audio, as it now has configurable settings. Thats why you have to configure it when you setup a QuickTime preset.

Thanks,
David
 
David,

That's odd, once I discovered the issue, I went to the Quicktime settings and they looked correct, so I left them alone. Of course, I don't fool with it that much once things are set to my liking, so I could be overlooking something I suppose, but I don't think I am. Anyway, it's working just fine now with 14. Oh, also did notice another odd thing, the audio was coming out of only the left channel in 15 at one point. But, once I moved back to 14 everything went back to normal.
 
I'm also having this issue. I've looked at all the configurable settings but there's nothing apearantly wrong. All the tracks are checked... looks fine. I'm not totally familiar with a couple things in there. I'll try going to V 14 unless I hear that the 16 beta has fixed this.

Here's my settings:
MacBook Pro 17" i7
Audible sound in redcine 15
No Audible Sound on Pro Res playing through quicktime 7

my settings:
In the Quicktime Audio Section:
Format: Linear PCM
Channels Stereo
Rate 48kHz
NO advanced settings (not possible)
Quality: Normal
Linear PCM Settings: Sample Rate 24 bits
Little Endian Unchecked.
All boxes below that are dimmed.

And then for the Audio TAB in the Edit (export) Preset window:
Camera Audio Channels 1-4 all checked
External Audio Channels: 1-8 All checked.

I may have had the same problem: v14 exported audio with my having to do anything. I installed v15 & audio suddenly did not come along with the video on Exporting.

I believe this is what fixed it for me: Under the Export tab in v15 (or I presume also for v16), try changing any setting under video or audio, and clicking OK. For example, change the frame rate to something 'wrong' and click OK enough to get you back to where you can Cancel the Export. Repeat, only this time change back to the 'correct' setting and now do the Export. If I got this right, it will get you your audio back. If this does not work, contact RED Support. Good luck !

Tx,
Serge
 
Same issue here!

We have footage that was shot on scarlet MOS. These are all master shots for a music video. We load the music track used for onset playback and proceeded to sync all the takes. They playback perfect on Redcine but when it comes to outputting I get MOS quicktimes. The quicktimes dont even have an audio track! We tried changing the export settings to BWF but redcine complaints that there is no audio to export. It will only export BWF IF you enable exporting of the internal audio, but that audio is EMPTY (remember it was a MOS shoot) and even on those BWF the external audio wont come thru.
 
I just found vs 14 in the version history, downloaded, installed, and voila - sound worked again. There may be other ways, but that way took less than 5 minutes of my time and worked like a charm. No need to uninstall or anything.

BTW, thanks for the tips Serge!
 
Tried V12, V14 and V15. None manage to export my external audio. Most puzzpling, specially since we have done over 100 days of dailies and audio sync!
 
Frank, try doing as Serge suggests. Go into one of your presets and change something and then save it. Then go back and reset things back and save it again, see if that doesn't work. It did for me.
 
No luck. Tried it in several versions already and I keep getting MOS quicktimes.

Since my audio starts later than the clip i thought that maybe the lack of audio at the beginning was throwing it off. So I trimmed the beginning of the take so it starts with audio but still no luck. I have a feeling that this most be a BUG related to recording MOS footage.
 
Dumb question, but are you letting the QT file completely export before trying to open? I did this awhile back not realizing the audio was the last part to build. It's a thought. But you may be right, could be another bug.
 
Shit.... BRB
 
That was it. I ran into the bug on V15 and tried V12 and V14 but out of desperation i wasn't letting the 5-6 minute long takes finish.

Tried to let one of em finish under v14 and all is good now. (Thanks Dual red rockets!!!! :)

thanks Mark!
