AVCHD audio tracks

I set my AVCHD camcorder to record stereo audio.
When I drop a scene onto the timeline, 3 audio tracks appear.
The top audio track is stereo and enabled.
In this respect it is like when I drop a clip from my DV AVI camcorder.
However there are 2 more tracks. I thought they may be Left & Right, but they are both stereo.
Are they the other 5.1 tracks, even though I only select stereo on the camcorder?
The camcorder is a Panasonic TM900.
Thanks,
Erik

Harm,
I thought that the number of tracks in the preset meant the number of available tracks appearing on the timeline.
I set the number to 1 - because I had recorded stereo - one (plus master) appeared.
But when I dropped an AVCHD clip, three stereo tracks appeared. If i drop an AVI clip, only one appears.
Does an AVCHD always contain 6 tracks? ie, set up for 5.1 irrespective of whether you select stereo on the camcorder?

No audio track with AVCHD files (shot on Panasonic HMC-70)

I've read quite a few treads and cannot figure this out. I have a standalone version of Premiere CC 7.0.0 (342) installed in my computer lab at school.
I tested the software with a creative cloud trial and AVCHD files worked fine.
This version does not show audio tracks in files dragged in from Media Browser (as suggested here: Audio and Video glitches | AVCHD footage)
It also will not import/transcode audio with Prelude or Media Encoder. Video works fine.
I have FCPX and Compressor installed. Both playback/transcode the file with no issue. Is there a solution for Premiere/Prelude/Encoder?

I tried renaming the folders, like all of them.
Not working.
The file path looks like this: Card:private/AVCHD (show package contents)/BDMV (show package contents)/STREAM/00000.MTS
I would think there would be a native format in Premiere for popular Panasonic cameras.

Choose different audio tracks in PE10 full version possible?!

Oky, I have tested this with Adobe PE10, but WHERE do I choose which audio track I want to import/use in the timeline?! Where can I see if the clip has more than 1 stream in Adobe Premiere Elements 10? I have tried looking in settings etc., but no luck. I KNOW that my video got 4 different audio tracks in it, but when I add the media to Adobe PE10 (it's a .m2ts-format file), only 1 stream (the DEFAULT audio stream, which is the WRONG stream) is what I get. Where are the other 3 audio streams, and how can I use them? It's nothing special about the clip itself. I can play the audio and video in the timeline, it just got the wrong audio stream...
I am asking because I see many articles/posts that mention you can do this in PE10, but I don't understand where... So far I have yet to find ANY video editing software that supports this.
And converting the audio FROM the .m2ts-file using a 3rd-party program is out of the question as well. If it does not work with PE10, then I have to find another solution, I suppose.

You do not have the option of choosing between the main track and the dub track from a video clip in Premiere Elements, Goodie. You just get the main track. So if that's what you're talking about, you'll need to look elsewhere. Though I'm not sure where because I don't know ANY video software that does this. What makes you think it's even available?
The exception is when you're shooting in 5.1 audio in AVCHD. If you've set your project up for 5.1 audio, you can control the level of each of the five tracks independently.

MultiCam Monitor Bug - mouse clicking dont swap audio track

"Audio Follows Video" ON
and "on play" it switch to MC1/2/3
but on pause switch only video track. And now i have video MC2 and audio MC3 for example. When use CTRL for new edit MC for video and audio are same. And all ok when switch with RMB. This bug only on MC Monitor mouse clicking.
my englih bad and i make video
http://www.youtube.com/watch?v=yrLL1MTgU00

ok in laymens terms I create a multicam sequence using four video tracks and four audio tracks. Normally the start of the sequence would have all the video audio tracks in, however I have started by editing single clips in time line 1. After a min or so I then import all the multicam footage to time lines 2,3,4. So the the actual sequence starts with clips on a single timeline as oppossed to all 4 video and sound tracks filled.
I multicam edit them in a new sequence and on final go to export but it fails. and it fails giving an "unknown error" message because the start of the multicam only has clips on one timeline.
However if I go to the synced sequence (original sequence) copy all the single edits at the beginning, then go to the multicammed sequence and paste these clip straight over the same clips in the multicamed sequence it then exports ok with no errors. I have to do this with every multicam edit I do which is a pain.
now the text above say if I repeat the same process in CS5 not CS5.5 there is no unknown error message and no need to fiddle about copying and pasting so why so in CS5.5?
I know your gonna say simple just do your multicam in CS5 but my main bought plugins and effects are for CS5.5 including native Canon MXF support and AVCHD support so I need the CS5.5 really. its bugged and needs fixing.
Better?

Premiere Pro CC 2014.2 and AVCHD audio bug

The AVCHD audio is mangled by Premiere. Details below.
I recorded a 2 act play and I'm editing it in Premiere. Each act is about 1 hour so the camera recorded spanning MTS files.
Act 1 imported perfectly. No problem.
When importing act 2, I noticed some audio glitches and the audio quickly lost sync. After further investigation, I found that:
- The AVCHD file plays perfectly fine in Quicktime player
- The audio track in Premiere is exactly half the length of the video
- When listening closely, it sounds like it plays 1 second, skips 1 second, plays 1 second, etc. Which is consistent with losing sync gradually and finishing the audio twice as fast as the video.
It seems related to the problem in this thread. I'm at a loss as to what to try next.

After posting the initial thread, I reinstalled Premiere Pro CC (7.0), created a new project, imported the AVCHD files and the audio was synched.
I then opened the file in CC 2014 and the audio was still synched.
So it appears to be a bug in AVCHD conforming in 2014 only. While not a fix, I hope this workaround will help others.

Premiere Pro CC and missing audio tracks for .mts files

Hello guys,
I used to edit my .mts files with Premiere Pro CC without any issues until yesterday.
Now I import my .mts file (made with a Sony VG900) but Premiere doesn't recognize the audio tracks (that I can hear just fine with VLC).
I tried changing the extension in .m2ts but it didn't work, I also tried reinstalling Premiere but, again, it didn't work and I tried (I was desperate) to install Premiere CS6 just to check if maybe the problem was just about the CC version. Guess what? It didn't work...
I tried also converting the file with Encoder in .mp4 but after the conversion I can't hear the audio with VLC and, of course, it doesn't work on Premiere.
Do you think it's a Premiere issue or a file problem?
I used those same files for other videos (like this one http://www.youtube.com/watch?v=H1X5vsZ-5yI) and I had no problems. Then I updated Premiere, I moved the files in other folder and the problem came to life.
Any idea?
(I'm waiting for my colleague to send me a new mts file just to check if I accidentally damanged the old ones).

A similar problem here..... although......
Take a look at this screenshot
As you will see, the blue marked audio is repeated audio of less than on sec. Certainly not the way it has been recorded.
I think I've got the answer........ (working with Premiere Pro CC, always up to date, Mac OX 10.9.2; Camera: Sony HXR NX3)
1. Don't copy but clone your flash card to the location where to edit on your hard drive. At the same time: alt+click on external flash card, draw it onto your hard drive location.
(or use carbon copy cloner, which I use for backup and transferring avchd files).
2. Don't import regularly via the import dialogue box (cmd-i). Instead: use the mediabrowser browser, locate the map "private" (as often standard named),
3. Via cmd-a (select all): select all videofiles.
4. click right mouse button and select import.
This way, all the video and audio files will be imported.
If however you have alreade re-used your camera flash card for recordings and don't have access to the 'corrupted' files to be imported into your project, you won't be able to solve the problem. You just lost some of the essential data which were not copied onto your Mac.
This solution I found for my problem may well be the one you are looking for........
Another solution might be to convert the compressed avchd - before importing into your project - into uncompressed .mov filed. However...... you will lose data so this is not exactly what I would prefer if the former described workflow does fix the problem for you.
Please let me know if this works for you or not.
Good luck!

Peter

Q about Audio tracks in PProCC

I've created a PProCC project, using AVCHD footage from a Panasonic DSLR. The original audio came in as a stereo track. I converted it to dual mono, because I read somewhere that would be a good idea, I don't remember exactly why!
Anyway,I've got my project put together, but when I go to edit audio in Audition, I notice that there is only 1 channel. And now looking back at the project, I see that both mono tracks are listed as Channel 1. When I edit in Audition, I'm only editing one channel. So what I need to know is, does the editing of that channel in Audition result in changes to both of my mono tracks in the original PProCC project, or just one? Thanks for your help! ~Bond

Well, that was a good and simple idea.
Exported mono track to Audition, added 5 sec silence at the beginning of the track. Saved in Audition.
Went back to PProCC, and sure enough only one track was affected.
I'm all about workflow, but I'm so mew at this I'm not at all surprised that it's an unusual workflow.
There's a lot of noise in these audio tracks - live theater recording, boomy room (which I know I can't do much about) but also several periods of obnoxious industrial noise - refrigeration unit going on next door, and whatever else - and I do think I can do something about that. But I'd like noise reduction to happen on both tracks in Audition, and it appears that I can't do that with the two mono tracks set up the way they are. So it appears that I've spent a ton of time trying to edit noise out of the audio, only to now discover that I've only been affecting one of the tracks, which is why, I guess, the noise isn't going away. Oy!!! Do I have any options for being able to edit both audio tracks simultaneously? Thanks for the help.

Video clip goes to different Timeline Video/Audio tracks

Premiere Pro CS5
When I move a clip to Timeline Video Track 1 the audio goes to Audio Track 4.
What might be happening?
I recorded the clip with Sony HDR CX560V
And I chose sequence preset AVCHD 1080i30 (60i) (I did this because Sony PMB shows the clip with a frame rate of 60i)

Thank you guys!!!
One other question. If I add background music to my clip does it matter if it's stereo and falls into a lower track? That is:
clip video = video track 1
clip audio = audio track 4
music = audio track 1
(By the way Ann, the guy on the link you sent me is awesome. Very clear explanation and right to the point.)

Replacing an audio track without re-encoding the video

I'm new to Audition CC so apologies for the basic question. I originally asked this in the Premiere Pro forum but I think it's more an Audition question.. I have AVCHD home video (MTS video with AC3 stereo audio) and have found I can clean up the audio, for example in speeches, very well in Audition. Is there a way to just replace the MTS's orginal audio track without re-encoding the video (which it seems I have to, if I do this via Premiere Pro)? In some cases the videos are poorly lit and any re-encoding makes them look noticeably worse than the original. In any event the video does not need re-encoding, I just need to replace the audio. Maybe I need to export the cleaned-up audio from Audition and use some other program to replace the audio in the original MTS file? Is that called re-muxing? Thanks in advance for any help.

Thanks Bob and Ryclark.
Bob, our aim is to copy these videos onto USB sticks, for our family to watch on our various home TVs, from a media player such as WD Home TV, a media PC or a laptop via HDMI cable. I expect the original MTS files, with cleaned up audio, will be fine. Media Info shows these to be video: AVC format, variable bit rate, 16.0 max bit rate, 1920x1080 pixels, 25.000 fps, 8 bit, interlaced; audio: AC3 format, 256 Kbps bit rate, 2 channels, 48.0 KHz sampling rate, 16 bits bit depth. I'm keen to avoid re-encoding the video, and it seems I can. My initial test worked and tonight (I'm in Australia) I'll test further... I can edit the AC3 audio in Audition, export it as a new AC3 with the same format as original, then use some other non-Adobe program to replace the original audio track with the new one, without touching the video.
Ryclark, I believe you are right. My novice-level understanding is that the process of separating the components of a video file such as my MTS file (video, audio and possibly others) into separate files is 'de-muxing' and putting them back together is re-muxing. Audition can save or export the original or edited audio track of my MTS file to a separate file so I assume that's like a specific audio de-mux. However I don't think Adobe products can re-mux without re-encoding the video (slow, larger resulting file size, worse video quality!), so I need some other program to replace my MTS file's audio with the new/edited audio.
So far I've found the free-ware Avidemux can do it but past experience is that free-ware can be a bit flaky or over time not as bullet-proof as a good/proven commercial product, so I'll look a bit further - or does someone in this forum know of such a product? HD Video Converter seems to be an option but it looks a bit amateurish.
By the way, if anyone is after a cut/join program to remove unwanted parts of a video without re-encoding the whole thing (ie. fast, same file size and unchanged video quality) I found Avidemux (free) only works on whole frames (GOP?) and the joins can have a little 'flick', whereas for $40-$50 a program like Fame Ring Smart Cutter for MTS videos (the Sony vidcam home video files I'm interested in) is frame accurate (it only re-encodes around the cut points) and works very well (smooth cut/join points). Smart Cutter doesn't do AVI videos (for my PC screen-recording videos) but I found SolveigMM Video Splitter Home Edition works well with those (not so well with my MTS files).

Premiere CS5 doesn't import AVCHD audio

Sorry out there, but I do need some help!
Premiere CS5 wont import the audio of AVCHD clips (1920x1080 50i) shot with a Panasonic AG-HMC151E.
Is it possible I miss an AC3 codec? Thanx

If the AC3 is fully Dolby-compliant, the full-paid version of PrPro will have not issue with it. I would assume that your camera WILL produce fully Dolby-compliant AC3's.
One of the issues with some AVCHD cameras is that they allow the user to record as DD 5.1 SS (6-channel), and PrPro will Import those into a 5.1 Audio Track. The rub comes with the Export from PrPro. It requires the Minnetonka Audio SurCode DD 5.1 SS encoder plug-in (costs extra), to Export as DD 5.1 SS, but PrPro will do a mix-down to 2-channel just fine.
Good luck,
Hunt
PS - if one DOES go for the SurCode plug-in, be sure to buy it from within PrPro, as they will get an Adobe discount below the price from the Minnetonka Audio site. It's only about US$50, but that counts.

AVCHD audio mixdown - how can I avoid this?

Importing AVCHD (AG-HMC150) using Log and Transfer. Doing this mixes the 2 audio tracks down to stereo, something I do not want FCP to do. Anybody out there got a good workaround to this problem as I need to keep the audio tracks separate.
FCP 7.0.1
Anyone at Apple know if they intend to fix this problem or if they are working on it. Sure would be a great help.

While my situation isn't the same as yours, it's a similar problem. We often use a Firestore on-camera recorder to record QuickTime files live to the unit's hard drive. When importing them into FCP, they have two audio channels set up as stereo. The workaround I use is to load all of the clips into a blank Timeline, select all and hit Option l (lowercase L) to change to two non-stereo and then Command l (lowercase L again) to unlink the audio from the video. I then delete the channel I don't need and set the pan on the first clip to 0 (centered). I copy that clip and then paste the Pan attribute to the remaining audio clips.
I know it sounds convoluted but it works and actually takes less than a minute to do all the clips.

On my ipad 2 I can't "see" the hundreds of spoken audio tracks that are in my itunes and on my ipod touch. Is there something I didn't do during sync up?

On my ipad 2 I can't "see" the hundreds of spoken audio tracks that are in my itunes and on my ipod touch. Is there something I didn't do during sync up? The tracks are from voice recordings that were downloaded from an extrernal drive and weren't necessarily tagged as spoken audio. Do I need to go back into itunes and relabel these tracks so they will show up on my ipad2?
Thanks in advance for your help!

With the iPad connected to the computer, while iTunes is running, click on the iPad name on the left side under devices. Click on the Movies tab and look for Movie Rentals. You want to "Move" the films to the iPad.

Multiclip - mutliple audio tracks

This question has been asked before, but I'll reiterate it. If the support doesn't exist, hopefully apple dev will take it into consideration.
I shoot a lot of weddings and events. FCP's 5.0.x multiclip feature has been a lifesaver. I know the short answer to the following question is "get a mixer and do it in the field right the first time," which I'm working on. BUT, in the meanwhile...
Setup: 3-camera live shoots. We run three different mics: one cam has a wireless lapel mic on the groom; another has a wireless with a directional mic placed at readers' podium/spot; last is an on-camera mic.
Throughout the event the different mics are better for different sound: lapel mic for vows, directional mic for speakers, on-camera mic for organ and songs.
My FCP workflow so far has been this (and it could be the problem): export audio to .aiff, tweak it in STP, bring back into FCP, and link it with clip.
Here's the issue (finally!): Whenever I make these clips a "multiclip," the audio tracks (six in this case) are all automatically mixed together into two tracks in the multi-clip. All my hard work tweaking sound in STP is lost. (Again, might be a workflow issue.)
Does anyone know how to import the audio tracks, while still linked to the video, into a multiclip (and avoid manual synching in FCP timeline)?
I know one solution is to bring the separate audio files in and synch them manually in the timeline. But here's hoping someone can suggest something a bit less time-consuming...
Thanks for any help!

Thanks for the reply.
Yes, the audio is set up with six total audio tracks (two per video feed). I'm viewing the clips with "Video & Audio" selected as you described.
I'm synching clips I've cleaned up in STP manually ... but that's not the issue.
Here's the issue:
Pre multiclip files:
V1 - A1, A2
V2 - A3, A4
V3 - A5, A6
--->convert to multiclip<---
Post multiclip files:
Viewer Window: V1, V2, V3 in multiclip config
Timeline Video: whichever angle I select
*Timeline Audio* - A1*, A2*
Going to item properties for the audio tracks shows that A1* is comprised of A1, A3, A5 and A2* is comprised of A2, A4, A6. All the original audio tracks are there in the new multclip audio, just mixed together.
I want to know if there's a way to separate those audio tracks in the timeline on the mutliclip. I'd like to work with the separate tracks for the best sound rather than the "mixed" audio that multiclip seems to do automatically.

Hello All...
Back after a brief absence, things look a little bit different.
I'm trying to take a 16 minute mini dv video and compress it for use on the web. I'm interested in any suggestions you may have on settings for the video and audio tracks. I've tried using Sorenson 3 (15 frames, key frames set to automatic, 320 x 240) for video and IMA 4:1 (mono) for audio. The resulting video looked great but the file size came in at about 255 Mb.
Thanks!

Thank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

2 Audio tracks on one video?

Hello,
I have two videos that are the close to the same...and are pretty close in length.
One of the AUDIOS i want to use for practice and the other for the Actual process.
So what i would like to do is set it up so either video can have BOTH audios.
People will be watching them many times so to keep them from getting board
with having one audio for one video. I want them to be able to change the audio.
So when watching one of the videos for a week with the practice audio
the can then watch the video next week with the Actual process
and visa versa for the other video.
I know there is a way to add subtitles or a different language to a video.
But these will be only 2 videos of 7 total in the DVD.
Is there a way to do this? if so could someone please explain or direct me to a video or tutorial
on how i might do this?
Thanks so Much!
Soshman

Here's one way:
The 5 videos with one audio will just be regular timelines. Lets call the two other videos with the 2 audios V1 and V2. And the two audios A1 and A2.
So you want one timeline with V1, and in Audio track 1 you will have A1, and in Audio track 2 you will haveA2. In another timeline with V2, you will have in Audio track 1 A2, and in Audio track 2 you will have A1.
You will have a menu that will select the audio track. See help:
