MXF Audio Channels

Why is it I can't changed he audio channels from 8 to 2 when selecting 1080i29.97 XDCAM HD 422 50 Mbs setting. I've duplicated the preset but it won't allow me to change it. Previously I was able to change this with Hamburg Medias MXF ForMac plugin.

Go to the Audio tab on the Export Settings dialog. There you can select the number of channels in the MXF export.

Premiere CS6 - MXF export with 8 channel audio does not export my audio channels correctly

Hey Volks,
when i try to export an mxf file with 8 channel audio, premiere does a kind of main mix in channel 1 and 2 and channel 3 to 8 remain silent. It does not include my assignment of audio channels in the mxf file.
im very thankful for any idea...

Hi Dast Media,
Have you resolve the multi channel export?
I have the same problem...(the export it's ok but i hear only the first two tracks)
i need to export a MXF file with 8 tracks, 6 stereo and 2 mono.
Thank you for help!

Mxf with 8 audio channels

Hey guys,
I`m editing a TV-Spot with Premiere CS6 and have to export it as a MXF OP1a (SMPTE 378M) (suffix .mxf) with 8 audio channels.
When exporting it with Pr the mxf has only two audio channels (I have re-imported it into Pr for checking the channels)
How do I get an mxf with 8 audio channels?
I`m a bit stranded as I`ve to finish it until tomorrow....
(video signal compliance: ITU-R BT.709)
Thanks so far!

Export MXF with multiple audio channels for broadcast

Hi,
I work at a broadcast company as an editor. We always used FCP with the free sony xdcam plugin to export. This plugin seems to be one of the rare ways to export an MXF with 4 audio channels. I don't know exactly why we need to export it for broadcasting with 4 audio channels, but we do.
Since our workload has grown enormously the last few months and it will only become more we are optimizing our workflow. We also work with a lot of different endboards in After Effects and we made a nice template to work with. And since AE and Premiere can make a dynamic link we are considering changing from FCP to Premiere.
Now comes the question!: The only obstacle we could not find an answer to is exporting it with 4 audio channels as an MXF from Premiere CS5. Will there be some development on this level regarding CS6?
A solution to this should save us a lot of time!
Any help will be highly appreciated!
I also attached an example for the usual MXF files we export

I have the same problem. I have a project with multiple audio channels and I want to export them as individual channels in a MXF-file.
Method:
When I created a new sequence I choose "Multichannel" from the "Tracks" page. When I export the MXF OP1a, I choose 8 channels from the "Audio" page. None of the channels are muted.
Result:
The rendered file contains 8 channels, but only the first two channels contains any audio (main left + right), the rest of the channels are empty. Channel 1 and 2 contains the audio from all channels, but I want the channels to be seperated in the same way as they are layered in Premiere.
I don't understand your answer to wleoni75's question. Could you please help me further?

Exporting multiple audio channels from Premiere Pro CS6 in MXF OP1a

I have a Premiere Pro project with multiple audio channels and I want to export them as individual channels in a MXF-file.
Method:
When I created a new sequence I choose "Multichannel" from the "Tracks" page. When I export the MXF OP1a, I choose 8 channels from the "Audio" page. I make sure that none of the channels are muted.
Result:
The rendered file contains 8 channels as I want it to, but only the first two channels contains audio (main left + right), the rest of the channels are empty. Channel 1 and 2 contains the audio from all channels, but I want the channels to be seperated in the same way as they are layered in Premiere.
Any ideas what I can do?
Thank you for your help!

Hey Guys,
I'm having problems exporting an 8 channel audio mxf for a broadcast client. The mix they want is as follows:
Track 01: Full Programme Mix L
Track 02: Full Programme Mix R
Track 03: International Sound L
Track 04: International Sound R
Track 05: Music and Effects L
Track 06: Music and Effects R
Track 07: VO Mono
Track 08: Interview Mono
I have setup the sequence following this video on vimeo and am fairly confident I have the sequence settings correct. https://vimeo.com/38501157
I also can export a multichannel mxf. But all my tracks are exported as mono and I am therefore not maintaining my L and R as set up in my sequence
The problem is on exporting that since Tracks 01 and 02 are bounced down to 1 + 2 it means that my Track 01 (Panned L) is getting bounced down onto my Track 02 aswell and thus it does not remain seperate. Has anyone delivered a similar format for a broadcaster and come across this problem with Premiere Pro and know a solution?
Any help would be much appreciated
Thanks

Missing one audio channel from MXF video

Greetings,
I have a bunch of footage shot with a Canon XF300 camera. Two wireless lav mics were feeding into the camera. On the day, I was monitoring audio and am 100% certain that it was recorded correctly. I found a couple of unerased CF cards from the shoot and was able to verify that the audio is good when I pop the CF card into the camera.
However, when I transfer the footage to hard disk and attempt to play it out using either Premier Pro CS5, or VLC, I'm losing channel one of the audio. I've been attempting to troubleshoot, and have found a couple of references on the Web regarding missing audio channel 1 from MXF video files -- but nothing that is relevant to this situation.
I'm on Mac OS X 10.6.6 and am running Premiere Pro CS5 5.0.3. No video cards.
I've tried bringing the files in using: Finder, XF Utility and ShotPutPro. I'm copying the complete directory structure in all cases.
Has anyone seen this problem before? Any troubleshooting thoughts?
Thanks,
Cameron

It turns out that the MXF files are coming in with 2 mono audio tracks, and for some reason, in the clip viewer, one of the audio tracks doesn't play, but if you move the clip to the timeline, both audio channels can be heard. Ran into the same issue with Cineform encoded material coming in with two mono audio tracks. So I'm going to file a bug report.
Ah, OK... now I understand. No need to file a bug report; maybe a feature request, but a bug report isn't necessary. Here's why:
When you bring in clips with mono channels, by default, you only hear the first mono channel when playing back in the Source Monitor. If you toggle over to Audio Waveform view (click the Output button), you can select which of the channels (called "Tracks" which is a little silly, frankly) you want to monitor. Here's what this looks like:
This applies to any format that has mono channels. If you interpret the footage to stereo (you must do this before you use it in a sequence), you can listen to both channels at once. Of course, then you have to deal with the audio as stereo, which is not always what you want. That's why I do a lot of my editing with MXF material (primarily P2) that has multiple mic sources in a sequence, where I can monitor more than one source channel.
In any event, that's why this isn't really a bug; it might be a poor design decision, but it's otherwise working correctly. I'd definitely suggest making a feature request for a "Mixed" or "Plus" audio source option in the Source Monitor. I'm going to do the same.
Anyway, I hope that helps explain the issue. Good luck!

CS 5.5 - Can I export Discrete Audio Channels w/ MXF OP1a

I created a new Sequence as 16 channel audio, each as mono. I've populated 8 channels.
I export an MXF 0P1a.
I brought the MXF back in and cut it to a new sequence to test the audio export. And on the new sequence the mix tool is only showing audio on the first 2 channels, even though the file imported with 8 channels. So it seems like PPro mixed the channels down.
Can I export an MXF with 8 discrete audio channels?

I have checked it and it doesn't work 6.0.3. I have proper 8 chanel audio on sequence and audio master shows this cannels properly. After exportin i have only 2 channels.
Please report how to do it properly.

PP CS5, importing mp4's I only get 1 audio channel instead of all 4...?

PC,
PP CS5, importing mp4's I only get 1 audio channel instead of all 4...? I put the clips in Vegas & all 4 channels appear. What can I do? Going insane!!!

It's pretty simple... when you know how
Get ffmbc - FFMedia Broadcast . This is a customized build of FFmpeg that is more geared toward broadcast formats and applications. The latest "official" release (0.5) will work.
Open the archive and find the "ffmbc.exe" file in the "bin" folder. Drop it into the folder with the MP4s--or if you know how to set up a custom path, you could do that too.
Create a new text file called something like "mp42mxf-4mono.bat" making sure that you can see file extensions; you need to have the .BAT extension. Make this file in the same folder as the MP4s and FFmbc.
Paste the following into the batch file:@ECHO OFF
for %%a in (*.mp4) do ffmbc -i "%%a" -vcodec copy -acodec pcm_s16le -f mxf -y "%%~na".mxf -acodec pcm_s16le -newaudio -acodec pcm_s16le -newaudio -acodec pcm_s16le -newaudio
Save it--again making sure it has a .BAT extension--and then double-click it to run it. It will rewrap all of the MP4s as MXF files that will import into Premiere. It will also retain the original four mono tracks as four mono tracks in the destination MXF.
That's all there is to it. Save that script, and you can recycle it whenever you get a batch of these types of problematic files in. Note that it's a completely lossless rewrapping, and should only take a few moments (or minutes, if you have a lot of footage, I suppose). Let me know how that goes.

File won't import due to 'Too many audio channels'

I've managered to import one 30 minute video recorded off a screen recording program off the AppStore called ScreenRecordStd. This software has an 'include computer audio' button which I activated after the first 30 minute video.
Once trying to import any videos with this selection activated they won't import, telling me there are too many audio channels.. so I know it is due to this selection. The file information tells me I have two AAC 44100 Hz Stereo files as part of the video, when I change it to mp4 or h264 file formats it does import but the video/audio are not in sync when played through on Premiere Pro but are totally fine in QuickTime player.. also the second audio channel is a lot quieter when being played through on Premiere Pro than in QuickTime.
So, I hoping someone has came across this software or this problem and can help me. So I have two 44100 Hz stereo files within the video and the selection I am using says it can take up to three stereo files, so why is it telling me it can't import because there's too many audio channels??? I've tried changing the video to h.264, mp4 and they just struggle with the video being too slow and avi. just has the same issues as .mov.
Can anyone help?
Thank you.

Why do you convert the media to start with? Are you aware of that you are converting the camera's MPEG2 to the MPEG2 you get when creating the new MXF file? (XDCAM HD = MPEG2)
I would never ever re-compress/convert the already-in-camera-compressed MPEG2 to compressed MPEG2 for editing and then having it to end up in let's say either MPEG2-DVD or H.264. You loose one generation and i would not want to lose it by re-encoding to MPEG2 since, imo, re-encodong MPEG2 to MPEG2 should be avoided. (MPEG2 to MPEG2 = The quality is degraded too much) If you still want to re-encode the footage i would use another codec, DNxHD/CineForm/Lagarith. (Pick your favorite)
You can use the MXF files from Canon XF Utility in CS6. (The files MXF are just copied from the original folder structure, so no re-encoding is done.)
AFAIK, the problems with tearing video go away by using the MXF files you get from XF Utility. If the tearing is still present, close Pr and delete all Cache files. Open Pr and let the Generating Peak file finish.
AFAIK 8 audio channels are standard in MXF OP1a according to SMPTE D10.

CS3 audio channel problem when importing to CS5

I have an HD P2 file-based project which I edited on CS3 which I now need to open in CS5. The P2 footage does not import and I get the following message:
'The selected file cannot be linked because it has 1 audio channel(s) and the clip has 2 audio channel(s)'
I tried importing the project instead of opening it and I get the same message.
I have also tried to offline all the material and see if I can re-link them. Unfortunately I cannot re-link the bin footage as I renamed them all to something meaningful for organisational purposes (eg 'Bill_says_hello' ) as opposed to the rather random naming of P2 files (such as 000R4X.mxf) so I don't know what bin file links with what P2 file, and there are about 2000 of them!
So either there is a way to view the original names of the bin files so I can match them up, or better still, another easier way to retrieve them or open them up automatically.
Without a solution to this, I have just lost months of work so any pointers would be much appreciated.

Thanks for the suggestion, Simon.
But finding to the first missing file brings up that message about the number of audio channels available which is still puzzling me, andthen making me link to them one by one. Not only is it tedious but I know it was stereo before and now it's mono !
I am sure when we recorded it our excellent sound guy would not made it mono so for some reason CS5 is not recognising the full gamut of sound channels recorded. So I am losing a lot of the sound, which is not good to say the least. I may have to start a new thread as to discover why.

Separate audio channel in avi

I am required to export a video with 4 separate audio tracks, and edit file to tape, I am using media encoder express from black magic... it doesnt support much formats....
The only way till now I can get out a video file containg 4 different separate audio channel is using mxf which can not be imported to media express... I can import avi files.... can I get avi video filel with 4 separate audio channels? any help please?

Hi
How do You record ? With what Camera ?
• 2 Stereo tracks - one with background one with voice ?
• 2 x 2 Stereo -
• 5:1 audio
• 7:1 audio
iMovie can use ONE Stereo Audio track.
To get audio OK I use
• Audacity (free from Internet) or
• GarageBand - where I can also do Audio works
BTW - to get full freedom - Use FinalCut Pro

4 audio channels into two

I have footage with 4 audio channels of a presenter giving a talk. Channels 1&3 and 2&4 appear to be from the same or simliar sources. I am not sure whether the paired sources are each from a single mic with different levels or separate mics. Can you advise the best way to combine these to get two channels of mono that could be balanced on the timeline to provide a stereo output.

Thanks Jim,
That's helpful, but it raises more issues. To try and see where this all
came from, I just did a test with my Sony PMW200. The two onboard mics were
switched off and separate mics attached to Ch1 and Ch2. Bringing in the MXF
files straight into Ppr results in 8 channels on the timeline. CH1 and Ch3
appear to be replicated as do CH2 and CH4. The other four channels are
blank. Sony assures me that the settings are correct on the PMW200 to
achieve two mono channels on the external inputs only. What am I doing
wrong?

AME merging audio channels

I have mxf clips with two channels of audio recorded on different microphones. The channels contain different content so I want to keep them separate. Media encoder (and every other transcoder that I have tried) merges the two channels into two identical channels. The only choices are mono (only gives me one channel), stereo (does the merging), and 5.1 (not appropriate).
Is there some way to convert the clips to Apple ProRes and keep the channels independent?
Thanks in advance for the help.

Catherine,
I've learned that this is a result of the fact that XDCAM is interpreted by default as split mono. The only option I've found within PPRO/AME to preserve the two original audio streams as separate channels is what I suggested earlier: drop the content onto a sequence in PPRO and use the Audio Mixer to put Audio 1 entirely on one channel and Audio 2 on the other.
A colleague suggested setting the source to Stereo through the Modify Clip dialog (in PPRO, right-click the clip, Modify>Audio Channels). I tried a few tests of that option in CS5.5 with no success, but that's not my area, so user error is an entirely plausible explanation.
I've entered two related feature requests that would enable AME users to avoid mixing streams without going through PPRO.

Get 4 audio channels out through SDI whit BlackMagic UltraStudio Express

Hi,
We have some issues with the Blackmagic UltraStudio Express and Premiere Pro.
We need to get out 4 audio channels through SDI for different broadcast and news feeds. We can't do that with the UltraStudio Express on different Mac Book Pro (one on OS 10.9 and one on 10.8.5) with Premiere pro CC and Premiere pro CS6. (We have try with the driver 9.9.3 and 9.6.8). The only thing we manage to monitor out of the UltraStudio is 2 audio channels.
We know it "could" work as :
- We are able with the same setup to get 4 audio channels via FCP 7.0
- We are able with a Mac Pro OS10.8.5 + Blackmagic Decklink HD Extreme 2 (driver 9.6.8) to get 4 audio channels with Adobe Premiere CC
Do you have maybe a solution for this ?
Have a nice day !
Best regards

My ipod's music quality is inferior. It doesnt have the surround sound/ left and right audio channel unlike my brothers ipod? is there a problem with the chip?

I have an ipod touch 4g (8GB), I got this about 2.5 months ago, the same time my brother get his. My problem is that I noticed that audio quality is better on his device than mine. I have been listening to music and had different music devices before (non-Apple product and mobile phone) and the quality of music is better when I used to listen to those devices as well as my brother's ipod touch. Im referring to the left and right audio channels. Im not so good about the technical stuff but the best explanation I can give you is in a music or a movie, there's an effect wherein you can here a sound only at the left ear phone/speaker that you cant hear at the right earphone/speaker. I mean for example in a song, a guitar intro can be heared only at the left
ear while the background music plays on the other ear. Or when theres and echo effect on the song that alternates sound on the left and right ear. I hope youre getting what Im trying to say. Im bothered that my ipod is fake or has an internal problem on the chips or something because I didnt bought this at an Apple Center/Mac Center. I bought it on a retailer. I am not able to visit any store or Genius Bar or contact an apple specialist through phone because of my work schedule and work load. I have contacted the retailer before when I tried to return it for replacement or repair but he told me that it is under Apple's warranty, not theirs. I do hope that I can get a help from you because I want to really enjoy my device. Thank you and Im looking forward for the responce/assistance form you.

I suggest you don't apply pressure to the screen - it's a Touch - you touch the screen not push it.
