View Full Version : r3d Audio on PC?
How are you guys getting audio out of r3d when you're on PC (i.e., using RedCine)?

It's not available right now. i guess you could export wav files from the proxies on a mac and then use them on windows or you could record to a DAT machine.
Ugh. I was afraid of that. Thanks Kinobairn.
I'll have to do just that for now.

Yes, you can export audio from proxies on a pc. Open the proxy file in qt pro and hit ctrl J.

I'm sure it will change very soon, and when it does, proxies on the PC will be great. They are great on OS X. As soon as saving color info back to proxies is enabled and audio is maintained from Ra, they'll be some really great things.

Did I miss the anouncement of Proxies working on PC? or are you just saying that the video is unsupported, but the audio is working? That would make sense.

Yeah, I am saying that you can extract the audio tracks from the proxies on PC. There is no access to the video portion of the proxy on PC yet.

Thanks Rfo for the great tip, it's true! I'm using WinXP, no access to a Mac. I was able to extract audio from the QT proxy in the "Chantelle With Audio" file that Shawn Nelson posted a while back (available at http://www.redrelay.net/owners/0027/ )
Opened in Quicktime Player Pro 7.4.1 and hit Ctrl-J as you said. This pops up a display showing video, audio and two timecode tracks. I selected "audio" and was able to play the audio, and also extract to a WAV format. I wasn't aware this would work on a PC.

This particular sound track exported as a 48 kHz, 32-bit mono WAV file.
Right on. Thank you Rfo. This totally worked (with QT 7.3 Pro).
I would never have figured that one out.

Does it allows you to extract two channels or only one?
I am getting mono, even when I record two channels (ch1 and ch2) on RED
Do you have two channels capability on Mac OS?

The sound track will contain all the channels you recorded. If you boomed to one channel and did backup wireless on a second channel, they will be there. There isn't anything different with the way the QuickTime environment works on the PC. Examine your channels and let QuickTime know how you wish to assign those channels.

Thanks! It works.
Had to go Ctrl-J and to assign the channels in the Audio Settings to Right and Left.

Great to hear the Windows world can access the audio. Just wondering if anyone has recorded four simultaneous audio tracks and used Quicktime Pro to split the Red's four channel audio into isolated tracks? Eg:
Wave file 1: Channel 1 left, Channel 2 right (or vice-versa)
Wave file 2: Channel 3 left, Channel 4 right (or vice-versa)
This is what we are hoping to do when our camera arrives with a view to bringing the wave files into an Adobe Premiere Pro/Cineform workflow.

I didn't combine 4 channels in to the pairs, but QT lets you assign the channels to almost anything.
RED will record 4 channels.
The problem I have now is processing of the Mid-Side (M/S) type of signal.
Most good microphones record in this format and the software I use Soundbooth doesn't have this ability.
I downloaded brainworkx plug-in and it kind of works but something is wrong.

Same thing with
http://www.kellyindustries.com/
plug in.
I do not get proper stereo image out of these process. It should do (M+S) for left channel and( M-S) for the right channel . Looks like these plug- ins are able to produce only (M+S)+M and (M-S)+M .
Adobe Audition has ability to analyze all these, but I can't download the trial version and I am not about to spend $300+ just to buy it and maybe I will never use it again.
BTW guys, if anybody has hiss using phantom power, just use M/S mike and do (M-S )and all noise will be cancelled to zero.
Optionally just invert one channel in post and feed mike signal inverted during recording to the other channel.
This trick cancels the noise completely and anything that is in this channel unless it is inverted.
Anybody was able to get Mid-Side type of recording out of the RED?
or someone could point me to the trial link of Adobe Audition, please.

Yes, I did try few more things.
First the noise(hiss) is not random, at least not on ch1 and ch2 I tested.
It looks like it is interference from the phantom power voltage converter and it is identical in phase and amplitude on both channels.
Taking ch1 and ch2 via one of the above plug-ins and combining it with the Right ch (ch2) inverted, cancels the hiss. I have noticed it when I was extracting right channel from the M-S mike.
To get right channel on this mikes you add ch1 and ch2 with second channel inverted.
Left channel you get by straight adding of ch1 and ch2.
Well finally I got all right and Mid-Side mike is working properly now.
I went further and recorded to all 4 channels.
QT lets you save each channel as a discreet ch 1, ch2, ch3 and ch4 or you can map it to Quadraphonic or to surround 4.0 and up or you can output any of two channels on L and any on R in Stereo mode.
Then you extract what you mapped, check it by playing it in QT (sound only) and then you export it in File->Export to whatever you have choices there including surround or Quadraphonic or plain Stereo or Mono.
To edit such .mov file you have to have surround audio card if you use Adobie Soundbooth. I think Audition will let you edit this files even if you have two channel sound card, didn't check it though.
You can fix the phantom power hiss by adding ch1 and ch2 (ch2 inverted).
To connect normal mike in such a way you have to connect one mono mike (balanced) via Y cable to both channels. Don't forget to invert ch2 cable from the mike (+ -) to (-+) on the balanced mikes only. If you have unbalanced mike then forget this trick.
If you do not invert the mike signal, then when you combine ch1 and ch2 inverted you cancel the hiss and the signal from the mike, thus getting pure silence.
Remember to use RED supplied cable with resistors inside, 200K across and 600 ohm in series!!

I transfered my R3D files and qt ref files from a mac hard drive to my pc hard drive and there is no audio when I playback the ref files in quicktime. The movie properties show the soundtrack has audio data but there is no sound on playback or when exported as a wav. Could I have lost the link to the R3D file when I copied it to my pc drive.

The QT Ref codec is Mac-only.

Ok, on PC.
Upgraded to pro QT, using 7.5.5
I loaded up the proxie file hit "cntr J" and got the pop up screen, but now I cannot select the audio track.
To get to this point I just loaded up my footage from the Red Drive to my PC,
Have I missed some basic part of this work around? That would be about my luck so far.

I'm having the same issue. On a PC with XP pro quicktime 7.5.5. I open up the quicktime file, press control J, shows there is a soundtrack, but I cannot click it in order to listen to or export the audio. :( Do I have to use an older version of quicktime?

I had to go back to v7.3 to export sound again.

Hey thanks for this thread, and all the info in it. It cleared up a lot of issues that I was having.
