No center & LFE audio on ac3 import

I am using Premiere Pro CS6v.6.0.5 with Surcode plugin. I am creating a project for final output to BD.
When I import any 5.1 ac3 file into the 5.1 track in the timeline the center channel and the LFE channels are not audible.
The ac3 file does include all 6 channels as verified in Audacity
When importing as 5.1 there is no option to map channels in the Audio Mixer (mapping pucks, changing levels not visible)
All channels appear in waveform when I double click on file in bin.
All channels appear in the bar graph Audio meter and Audio Mixer panels
No C/LFE heard.
As a workaround I tried importing ac3 as 6 channel mono on standard tracks where I do have the option of mapping each channel in DD format (L,R,C,LFE,LS,RS)
I map each channel as above, leaving the levels in the default position.
All channels appear as waveform when double clicked.
All 6 channels appear in the Audio Mixer but only 4 show in the Audio Meter panel (no C/LFE).
I have Center channel audio to edit with, however, after encoding, all audio is mixed into channels 1,2 & 5,6 with no audio in channel 3 & 4 (C/LFE)
This is confirmed using Audacity to check the channels.
Now if I move the C/LFE pucks to max position when editing I will lose the C/LFE audio to edit with but there are now 6 channels appearing in both the Mixer and Meter.
When I encode the project the channels will map properly, however, if I bring the file back into PP there is no C/LFE audio once again.
Is there a setting that I have missed that is causing the C/LFE not to be played back and ultimately encoded improperly?
Apologies for the length of this question. If any further info is needed please let me know.
Thanks!

I have tried both leaving them in the default position and adjusting them to the Dolby Digital L,R,C,LFE... - the issue remains. I have also determined the issue is not only with ac3 but with wav as well. This leads me to believe there is a mapping issue here. Perhaps if I start afresh. What is the correct Audio Output Mapping and Rt click>Modify>Audio Channels settings for using a 5.1 ac3 DD file so it can be encoded properly? I will start there and work forward. Thanks again for any ehlp.

Hi, I have problem with importing MOV files from SJCAM 4000. MOV files are in supported formats for Adobe Premiere Elements 11. But if I'm importing MOV file, only audio part is imported, video part is not imported. How can I solve this problem?

haben
From looking at the specifications of your camera (SJCam 4000), we know already what video compression your camera is using. It is H.264.
A H.264.mov file should be supported by Premiere Elements 11. On what computer operating system is your Premiere Elements 11 running?
Do you have the latest version of QuickTime installed on your computer? And, are you running QuickTime and Premiere Elements 11 from a
User Account with administrative privileges? Please go to Premiere Elements 11 Publish+Share/Computer/QuickTime to confirm that you find
presets there for the QuickTime choice there.
What are the properties of these H.264.mov files - is it 1080p30 (1920 x 1080p30) or something else? Do you know if this camera is recording with a variable or
a constant frame rate?
Please review and consider and then we will decide what next.
Thank you.

FAQ: How do I troubleshoot audio issues when importing .MTS files?

Hello. The link FAQ: How do I troubleshoot audio issues when importing .MTS files?
does not work, and i need the answer please. My imported MTS clips are not playing back audio because it seems that no audio imported with the video. Thanks, Don.

Hi there
Audio plays when the object with the audio assigned appears. This is why you hear it when the Button appears.
Try assigning the audio instead to the object that appears when you click the button. Perhaps the caption.
Cheers... Rick

Audio Drift when importing VHS Tapes-Do I need a Canopus ADVC 300

Embarking on the daunting task of importing/editting >100 2hr VHS tapes, and want to get the best results for my efforts.
I pop a tape into a VCR connected via S-Video (video) and RCA (audio) cables to a Sony DVMC-DA1 AD converter, and from there to my Mac Pro via Firewire. Use FCE "Capture Now" using NTSC DV Converter setup. Start capture, let it run unattended, and return at my leisure to do some rough editting.
Problem is the audio on the imported clip gradually loses sync, by about 2 seconds by the end of the clip. The sync problem is present on the clip when played with Quicktime as well.
Questions:
1. Is there a reasonable way to correct this in FCE?
2. Since my Sony converter is nearing 10 years old, will use of a more recent AD converter such as the Canopus ADVC 300 result in a perfectly synced import?
3. If so, can you comment on the Canopus's purported video noise reduction and image stabilization capabilities? Is it noticable/worthwhile?
Thanks for your time.

Hello,
The problem is the audio is not 'locked' to the video, and your old Sony DVMC-DA1 does not appear to support locked audio.
The only way you might deal with this in FCE itself would be to capture shorter clips (say, under 15 minutes each) which would minimize the degree to which the audio drifts out of sync in each clip. (The longer the clip, the greater the drift.)
Given the large amount of video you wish to digitize (some 200 hours), it will be far preferable to use a Canopus ADVC-100, 110 or higher model - +they all support DV locked audio+ - so the video & audio are sync'd without the need for manual intervention or capturing short clips.
I have used the Canopus 100 & 110 extensively and have been very happy with the results. Sometimes, depending on the VHS tape, there is some slight banding at the very bottom of the image but 1) this is +usually not visible+ in the finished movie because it is outside the 'image safe area' and 2) if necessary can be compensated via about a 2%-4% enlargement of the image in FCE (which is not enough to soften the image).
I have not used the Canopus 300 because I never felt the need, as I am happy with my results from the 100 & 110. Users of the 300 have been pretty positive about its built-in TBC and image cleaning capabilities.

What's the highest quality audio format to import CD?

I've a 40 GB iPod. the system default to AAC. But i'm planning to buy a Shure e4c ear-plug and want to make sure i've the best quality audio format recording in the ipod.
could someone tell me what audio format yields the best audio quality to import CD? i'm only used less than 20GB of the ipod.
so i don't mind using the best audio format which may take the most space.

Simple answer: Apple Lossless. You will hear the song at the same audio quality level as on the CD--at about half the size.

How do you convert audio to ac3 in DVD SP 4 without a.pack

how do you convert audio to ac3 in DVD SP 4 without a.pack
thanks
Josh

NO. If you let DVDSP make your encoding you'll get uncompressed audio (AIFF/PCM) what means most probably high bitrate issues during building/playback and a lot of the space of your disc.

Video bit rate too high when try to build and burn. Audio is AC3

I am trying to burn a dual layer DVD and when I go to build/format the DVD it says that the video bit rate is too high. I am confused by this because this DVD was burned previously without a problem. Changes had to be made to the project and the files were compressed in compressor with the same settings and now they do not work. The audio is AC3 dolby. Is there some setting that needs to be changed in DVDSP? What am I missing here...
I am using FC Studio 2.
Thanks!
Natalie

I don't know exactly what the total length of the video is in minutes, but I do know that it is 6.8GB for a dual layer. Probably at least 3 hours. I don't know what the target bit rate is? Is what you are referring is to what the compression I used in compressor?
I am using the setting DVD Best Quality 150 minutes 3.7mbps for video and the AC3 for the audio.
I am recompressing all the videos again just in case there was a problem with one of the compressions. I don't understand why it isn't working this time when none of the settings or compression had changed.
Thanks!!

.mov audio doesn't import

I've been importing a .mov file that has audio but the audio doesn't import. What should I do?

According to Flash's Help…
"If you attempt to import a file format that is not supported on your system, a warning message appears that the operation cannot be completed. In some cases, Flash might import the video but not the audio in a file. For example, audio is not supported in MPG and MPEG files imported with QuickTime 7 on Mac OS. In such cases, a warning indicates that the audio portion of the file cannot be imported. You can import the video without sound."
So this may be an issue with the format of your particular video clip. If you have Quicktime Pro, you can try exporting the movie again using a different format for your sound options such as "AAC" or something.

TS2289 Audio won't import with video in iMovie 11

My iMovie 11 (9.0.4) is all of the sudden malfunctioning - it's not importing the audio with the video. I've even tried importing clips that just a few days ago imported perfectly with the audio... but now the audio isn't importing. So I know it's not a problem with the video file. And I know that I have the volume up in iMovie... the intro w/ music that I have in iMovie is playing the audio perfectly. The problem is with importing a video file (mp4). I've literally imported hundreds of video clips into iMovie, and have never had this problem. My Mac is 10.6.8. Any suggestions?

I'm using imovie 9.0.9 with OSX 10.7.5
I also went through days of troubleshooting why some clips have sound and some don't. All quicktime files have sound when played from quicktime. But no sound when imported into imovie.
None of the Apple or User suggestions worked. But I finally found a solution. I'm working on a project with over 100 clips. Everything was fine until I tried to import around 20 clips at the same time. Some had sound some didn't. Also, when done with each section, I exported the movies and deleted the thumbnails from the imovie clips window to clean up and organize the session. When re importing clips which previously had sound, the sound was gone but the image would play.
What I found was that any file which had been deleted from the clips window, was now in the Rejected Clips window. Re importing the file would only show image but no sound. Once I Move Rejected Clips to Trash, emptied the finder trash, and re imported the files, all files played with sound.

Audio problem when importing video files.

Hello everyone,
I just started using FCP X a few days ago for a university project and I seem to encounter an audio problem when importing videos in .mp4, .mov format or via the import from camera option.
Indeed I need to import videos in .mp4 and .mov format into FCP X. The import in itself is normal I can see my videos into the events/clips library and if I play them from the library I can hear the sound quite perfectly.
However, when I want to edit my videos and put it in the timeline, there is no audio. As a result I started to think that my videos could be the problem so I tried the option "import from camera" option using the Isight camera of my macbook pro but the same things happened. I could hear the sound from the events/clips library but not from the timeline (I can't see any audiowaves in the timeline).
I found a solution using quicktime and extracting the audio of the video in .m4a then importing the videos files and the audi files corresponding but it's a long process and a waste of time as FCP X should be able to import the audio of my video into the timeline directly. Especially if it can read it from events/clips library.
I hope I explained myself clearly and you could help me resolve my problem.
Cheers
Christophe
PS: I'm using FCP X version 10.0

Update to 10.0.5.
You have an incorrect setting when you edit. Try trashing your preferences. Post screen shots of your timeline and toolbar.

Trouble with audio files when imported from audio window

after "bouncing" and audio region and importing it (onto a new track) into the arrange window from the audio window, I can't seem to control any parameters like volume and pan for the imported clip. Is this somehow locked?

sure....say I record a clip in track one with a bunch of plugins....export the clip to the audio region...then import back to the arrange...
First of all it won't let me play the clip in Track 2, but if I shift the clip to track 3 it'll play....BUT I can't control the volume or pan .....very strange. I hate freezing stuff...although I have been for ages....but if this works it'll be cool....
Thanks...

Controlling which RED audio tracks to import

Is there any way to control which audio tracks are imported when working with RED R3D files?
This is probably user error, but the company that we use for Red shoots has their camera set up so that the talent audio is on track 2 (with track 1 and 3 being empty, but still active). So I get three mono tracks for each clip I import.

After you import, and before you use any of the clips in a sequence, select them and go to Clip > Modify > Audio Channels. There are a number of options in that dialog for mapping source audio channels as you need.

Hi,
I don't have GraphicConverter and since it is shareware and money is tight right now, I tried to find a freeware image converter on the internet for the Mac. I didn't. I remembered that I have Photoshop Essentials. It came with my Canon scanner. I installed it and looked to see if it had a converter of some type in it. I saw that you can import a file, work with it and then save it to what you want. I thought that I had already done that with the Nikon files. Anyway, I tested it. I imported one of the Nikon images into it and saved it as a jpeg- even though it appeared to be a jpeg already. Bingo! It worked. It imported into my video editing program. I selected two other files from the Nikon shots and did the same thing. I change the name of the picture and then save it as a jpeg in Photoshop Essentials 2. The two files imported into my video editing program. I then went to the two original Nikon files that I had imported into Photoshop Essentials 2 and changed the names of them- leaving the jpeg extension on to see if they would import, they did not. So, as you said, there must by some kind of Metadata with those files. Bringing them into Photoshop Essentials 2 and saving them as jpegs fixed it. Because of what happened, I just went through my approx. 4,000 pictures and selected about 1,400 again for a new family DVD. I created folder and exported 1,446 jpeg pictures into it. Then I opened by video editing program and imported the folder. All 1,446 pictures came in. I didn't try it with FCE and iMovie, since I the program I regularly use is Adobe Premiere. I may try it later, but I am pretty confident that if the pictures can be imported into Adobe Premiere, they can also be imported into FCE and iMovie(unless there is a number limit.)
All this has taken place over several days. I am glad that it is figured out.
Thank you for the help.
