12 bit audio synch issues

Hey all. I have a queation regarding 12 bit audio synch problems. I have digitized a tape recorded with 12 bit audio and am just now coming into video/audio synch issues and was wondering if anyone might have a workflow suggestion. Soecific questions are -
1 - Can I export the troubled clips to quicktime/ resample them at 16 bit and reimport?
2 - Some of the clips I already have edited and are in synch, do I need to correct them as well or will final cut do that on export?
3 - If I get a 12 bit/16 bit mixed bag on my timeline, can I export the mix to 2 track and convert before exporting it to compression?
ANy suggestions on how to work through this would be appreciated. I seem to have a lot of people coming to me with this setting and would like to know of any viable workflow solutions.
Thanks

1. Yes. Quicktime Pro, iTunes or third party audio editing software such as Peak can resample to 48khz/ 16 bit.
2. It would be best if you can get everything in the timeline to be 48khz/16 bit.
3. See #2.
Dope slap these fools who bring you 32khz stuff. Charge them MUCHO extra for your time.

Audio synch issues in QT

My project displays fine in PE8. No audio synch issues in the preview. After outputting the project to a quicktime movie withe LAN setting the audio becomes seems to run faster than the video, becoming more and more out of synch as the movie plays. Any ideas what might cause such an issue?

The Stream info in MPEG streamclip for files from both cameras gives me this info:
Bitrate: 30.31 Mpbs
Video Tracks:
DV/DVCPRO - NTSC, 720x480, 16:9, 29.9699999999999 fps, 28.77 Mbps
Audio Tracks:
16-Bit Little Endian mono, 48 khz, 768 kbps
I don't know if this helps.

Audio Synch issue

Hi,
So I have a .mov source file that contains footage captured from a Sony MiniDV camera (don't ask me why we were still using that in November of last year) and I believe I possibly screwed up the capture settings. The footage is 50 minutes of uncut interview and the audio gradually falls out of synch so that by the end it's about a half to a full second slower than the video. We need to edit the file simply to trim the ends so we have a clean fade in and out.
Here's the info on the file as displayed by the Finder
I imported it into Premiere Pro CS6, put it onto a sequence, and clicked "change sequence settings" to match the clip settings.
Here are the resulting settings:
I unlinked the audio track and moved it so that the sound of the two people high fiving was synched with the video. I cut both the video and audio tracks at that frame, deleted what came after the cut, and moved the audio back to its original position. I then looked at the duration of the video track, and adjusted the duration of the audio track to match. The result was that the audio speed was adjusted to 100.03%, and appeared synched throughout the video.
I thought I had solved my problem; however, when I exported the video the audio went back to falling out of synch slowly, exactly as it does in the source file.
I exported it initially as Format: H.264, Preset: NTSC DV. Then I exported it as H.264, Youtube HD 720p 23.976. Neither worked. The sample rate for both was 48 kHz, so unless I am mistaken, that matched the rate from the source audio.
This is beyond my technical ability and I don't know where to begin fixing it at this point. I no longer have the tape that the footage was on so I can't recapture it. How do I synch the audio and video?
Any help would be much appreciated.
Thanks!
Collin

Yes, the second export that I tried was with the Preset that is YouTube HD 720p 23.976. I've done this before with DV footage and it works fine, all that happens is that there are two thick black bars on the sides of the video. I only did this for one of the exports on this particular project though. The first time I tried to export it it was with the NTSC DV preset, and the synch issue was still a problem. So it is independent of the pixel ratio.

12 bit audio synch Q?

So my mom recorded this video for me. on the camera(canon Elura) it says 12 bit on the screen as it plays. It also records in anamorphic. So i hve been trying to capture in dv ntsc anamorphic . .whis works fine except that after i capture i get an error message saying something like "ther was a problem capturing audio, your audio may not be in synch." Offten the audio isnt in synch, and sometimes it looks like it might be but i cant tell. It seems like final cut captures at 16 bit. .. . .how do i capture the audio for this video???? Thanks for your help.

You need to create a new capture preset that changes the audio rate to 32 kHz 16 bit for 12 bit DV recordings.

TS3591 iphone 5 and Windows Vista, and itunes audio synch issues

the new itunes is not synching my music to my iphone 5. I have windows Vista. Upon synching itunes crashes the phone and forces a restore. Any one else have this problem?

Same exact problem with my iPhone 4. I have reinstalled iTunes hoping it would do the trick and it didn't. :\

HDV audio synch error upon capture

I'm having issues with audio synch capture issues.
I set the project settings for HDV 1080i30(60i) - I accepted the defaults of preset, I specified Canon in Device Control
I captured two clips...each ~ 20 minutes in length. Both have audio synch issues.
Both clips captured footage that included a blank spot(s) in the tape...ie. the timecode was reset when I removed the tape from the camcorder during the trip.
Both captured clips have odd bright red video footage inserted for a second or two (is that an error signal?) in various places.
Both show the following error message:
F;\Video\Project1\Clip 02.mgegError in MPEG stream detected around frame 3502
(there are ~20 such error messages in the Events panel)
Suggestions?
Thanks, in advance.

Thanks for your continued advice.
Doing the resiz in camera makes a lot of sense. My only concern is not wanting to do my edits and titling for a large project twice (i.e. once for DVD version and later for a BR version). I know there's some feature of Prem. that allows substitute clips...work on low-res & replace with high-res...but I'm a rookie on that front. Is there a term for that?
As mentioned earlier, I was willing to try doing a manual capture process in order to work around the timecode breaks. But I'm running into issues, again. The first clip ~2 minutes - no problem. The second clip ~35 minutes - big problems...error reports of dropped frames...must be on portions of the tape other than my timecode breaks. Also, the thing can't complete the Conforming Clip 02b.mpeg process. It starts...makes progress...grinds to a halt mid-way...and renders Prem "Non Responsive".
It's feeling like this HDV full res process has lots of gotcha's. I'm wondering how folks get through it.

Exporting from PPro CC - Exporting using Match Sequence Settings issue with 24 bit audio

I am having an issue exporting my sequence which contains final AIFF mix (24 bit 48 kHz) into a 'same-as-source' ProRes 422 file with 24 bit audio. I am specifically trying to export media with 'Match Sequence Settings' checked to create an identical output of what my sequence is. I wind up only creating a PR422 with 16 bit audio rather than 24 bit audio.
My sequence contains ProRes 422 media and 24 bit AIFF final stereo mix (1 audio file) from our Sound department.
My sequence is currently setup as "Custom" at 1920x1080, 23.976 fps, Square Pixels, Progressive, etc. Audio is 48 kHz (I don't see an option for choosing different bit rates in the 'Sequence Settings').
Using 'Match Sequence Settings', my options to alter the audio are "greyed out" and unavailable. I'm not sure why 'Match Sequence Settings' doesn't recognize that I am cutting with 24 bit audio and, instead, only exports 16 bit audio.

Always skip Match Sequence Settings and set up the export manually.

Audio and Video Synch Issues

Is there a way to fix the audio/video issue in playback? I know adobe pro warns you that it does that, but is it only during previewing or will it also do this when the file is published?

You are talking about directly embedding the video into the main timeline, correct?
For the most part, believe what Adobe says about not embedding video in the timeline or you may have audio sync problems..... which are actually video syncing problems. The auto will play exactly as it's supposed to, it's the video that gets out of sync.... NOT the audio.
The problem usually come up because you are attempting to match the audio up with the video... which is really the wrong way to go about it. Video can to speed up a little or slowwed down a little without really affecting the end result that much.
Not so with audio! Any speeding up or slowing down in an attempt to "match up" with the video, changes the frequence of the audio, distorting the sound. That only makes sense, right?
So if you have one minute of audio, you can't change that to 1:05 by slowing it down slightly, and you can't speed it up to play in :55 unless you want a little "chipmunk" effect. Either method changes the frequency and pitch of the sound.
Understanding that is key to using this particular embed method.
So if for some reason I just have to embed a video, here's a method that works pretty well for me. Set the Flash doc frame rate to exactly match the frame rate of the original video.
That means, for example, if the video was captured at 29.97 frames per sec., set the Flash doc to exactly match that....29.97fps. This will tend to keep the video and audio pretty well synced.
Here is a quick sample of an embedded video. The video bitrate is 400kbps.
http://www.cidigitalmedia.com/tutorials/vid_sync/vid_sync.html
You can test and judge for yourself how well this method works.
Now there are some potential problems. If the video bitrate is too high, the video may not download fast enough... just like any other high bitrate video. Second, there are Flash timeline limits, so you can't really embed a 20 min. video into the timeline and expect it to work.... but then you shouldn't really be using the "embed in timeline" method anyway.
But it is possible to get pretty good results with short videos (with audio) embedded directly into the main timeline provided you set the Flash doc framerate to exactly match the original video and you use a reasonable video bitrate.

Can Apple fix the 12 bit audio problem once and for all?

I have had persistent audio problems from I Life V3 all the way up to I Life 06. Sometimes it is synch issues. Sometimes it is audio dropping out. I have been through the various forums and applied the various remedies with some successs, some failure. The basic problem is that I have an extensive quantity of Mini DV tapes dating back to 1997, most recorded with 12 bit sound (prior to 2002). Apple's basic stance has been, you must use 16 bit sound or I Movie and/or I DVD won't work and . And proposes awkward workarounds. Basically placing the onus on it's own consumers. Why can't 12 bit sound support be included in I DVD 06 and these persistent audio issues put to rest once and for all? Is there some overwhelming technical reason why it cannot be done?

I don't know about overwhelming, but the DVD specification (which was not developed by Apple) calls for the audio to be sampled at 16-bit/48KHz (I think you might also be able to use 96KHz as well). This is what the software expects. If you choose to use another sample rate then the software may or may not be able to "fix" it in post. The real problem is that many camcorder manufactures set the audio to 12-bit by default.

Audio Synch Problem Exporting From imovie 6

I have a created a large imovie project in imovie 6 using pictures and imported video. The project uses a lot of extracted audio voice overs on top of the photos.
While trying to export the video to quicktime or idvd, the audio gets out of synch at various points. I have tried exporting it many times using a variety of different options, and the audio remains out of synch, sometimes in different places with each export. Lastly, I have extracted the audio from the video clips for some of the more problematic portions of the project, but that has not proven successful.
The odd thing is that the movie plays perfectly while in imovie.
Any suggestions as to how to correct this issue?

Hi
Tedious situation.
To avoid this I'm kind of strict in Audio in two ways
A
• Material used if video is in same frame per minute - else I use JES_Deinterlacer to convert all to one standard. I use PAL = 25fps - one of my Cameras records ONLY in 30fps - (some people records in 24fps - to get a movie feel - I never)
So keeping the fps from Camera to (in my cases) DVD - gives a supperior result
B
• I'm strict in the kind of Audio formats I use - ONLY .aiff (or from miniDV tape Cameras) AND THEN 16-bit 48kHz or from Audio-CD (still .aiff as on normal CDs) and here 44.1kHz
If Camera is set to record in LP-mode or 12-bit Audio - Then I use an external Audio Editor to get this right
If from iTunes - I never use this directly - BUT - collect needed audio into a New PlayList - BURN THIS as a Standard Audio-CD (NO .mp3 - but .aiff here too) and then use the files on this CD in my movie project's in iMovie HD6 or FinalCut any varsion (or if forced to - iMovie'11)
Else read this
Audio Sync problems
• 12.bit - should be 16.-bit (from miniDV tape - set Camera right)
Avoid recording in LP-mode on miniDV tape. This tape must be play-backed by same Camera. When Camera dies
so does the video material in worst case.
• .mp3, .avi etc strange file formats - should be converted to .aiff 48kHz 16-bit
• in iMovie (up to HD6) - do - Extract Audio - it most often helps
• from iTunes - collect into a PlayList then Export out as an Audio-CD (not .mp3) and use the files on this (.aiff 44.1kHz)
• There seems to be a problem with slow-down resp speed-up. Has to be in specific steps as 25% 50% 150% 200%
else problems will arise
• Audio problems when transitions is in use - especially iMovie HD/HD6
a. Select video clips
b. Extract Audio (Advance menu/Extract Audio)
c. Now apply transition
d. eventually fine-tune end and start of extracted audio clips

Audio synch problem from 24 to 29.97

I am working for a tv show that is having a major audio synch problem.
We send our mix to an external sound house for our pro-tools mix. They request the file to be 29.97, though our timeline is 24. In turn, we export a 24 time line, re-import to an 29.97 timeline and than re-export at 29.97 with a time code burn. They export the mix, using a sound compressor that converts the mix to a 24 fps synch, we send them a 24 frame export that they can check it againest on their end in Final Cut Pro. For them, both the opening and end two-pop lines up. When we recieve the mix back however, and bring it onto our timeline, it is always 24 frames ahead of the picture. We can't fiugre out why.
I know this all sound very confusing.
Below is our export and timeline settings:
OUR TIME-LINE\EXPORT SETTINGS:
1st Time Line:
FS: 1280x1080

Aud Rate: 48.0 KHz
Aud Format: 24-bit Integer
Total Out: The audio is exactly 24 frames ahead of the video by the end of the clip
We shot on a Panasonic HDX900
Can anybody think why this might be happening?

ProTools mixes 24fps...and 23.98, which SHOULD be the case here. There is NO REASON why they should want a 29.97 mix, nor should they mix at that rate...because you are not working at that rate nor delivering that rate...are you?
Your sequence settings confuse me. DVCPRO HD 1080i60 runs at 59.94. You can get it to 23.98 with a little work...but you indicate 24fps. Is that SOLID 24fps? Not 23.98? If so...that is a major issue. You should not be working at 24fps. 23.98 is the frame rate...
Still...if you are working at 23.98 and delivering a 23.98 master, the audio guy needs to mix at 23.98. ProTools is capable of 23.98. If they can't do that, then I'd suggest finding another mixer.

Synching Issues with iphone 4/ itunes

When attempting to synch my iphone with itunes, the synch cannot progress past the "backing up" stage. Why?? Getting a bit frustrated now to be honest.
Every time I plug my phone into the computer, itunes informs me of the latest update required (4.3.5), but because of the synching issue, I obviously can't get the new update.
any help appreciated

"iTunes could not back up the iPhone "Guru's iPhone" because the backup was corrupt or not compatible with the iPhone. Delete the backup for this iPhone, then try again."
The above is the error message I receive when trying to upgrade/ synch my iPhone with iTunes on my Laptop. I have the latest version of iTunes available (10.4.1)

How do I get the most of my 24 bit audio?

We recently shot a project where all our audio was sent to digital recorders at 24 bit, 48k... when I import the files to Premiere there doesn't seem to be any issues, but I can't find settings when creating a new sequence that allows for 24 bit audio (just 12 and 16 bit). If anyone could help me understand the following I would greatly appreciate it:
1. Are there settings for using 24 bit audio in a sequence? If so, where?
2. If there are no 24 bit settings, does that mean my project refers to the original high quality file even though the sequence is set at 16 bit? Or is my 24 bit audio being modified to 16 bit when I drop it into the sequence?
3. I guess the main question is: is it worth it for me to use 24 bit audio in my Premiere projects?
Thank you for the help.

Hi,
When working with *24bits in a *32 bits floating-point internal environment you have *8 extra bits (these are *wordlengths and have nothing to do with the sample frequency as stated above!) and gives you virtually a endless headroom ( even above 0 db on individual channels).
But at the end (after the master and out of your soundcard that is ***16 or 24 bits) the wordlength gets changed (shortened from 32 to 24 or *** 16 bits) and the sample frequency sampled down eventually as well, the master output has to stay a *little under 0 db *depending of the type of sound.
To answer your question: "It makes perfect sense to work with larger wordlenghts, because no matter you go down to 16 bits at the end, you have a much better sound quality and bigger headroom during mixing and at the end even when it's downsized to 16 bits."
***16 bits in Premiere Pro

Audio Sync Issues During Final Render

I am working with school students to produce short film projects using iMovie HD 6.0.3 and I view their work before they render it and it looks and sounds fine. While the computers they work on are slower than mine (iMac G4 1.33ghz 500mb Ram) they manage fine in live playback. However when we render the files at full quality (ie. no further compression) random elements of audio move around and pop up in the wrong parts of the film.
At first I thought this was a processing issue and using an external drive transferred their entire edit file to my laptop and shared it there. Once again fine in live playback, exactly the same errors while viewing through quick time or VLC etc.
What am I missing?

Hi A
Just thinking:
• material recorded in 16-bit audio (not 12-bit)
• material recorded in SP-mode (not in LP-mode)
• free space on internal (start-up) hard disk > 25Gb
• using external hd: Formatted Mac OS Extended - nothing else
• lot's of audio-clips: mix together to one big .aiff audio file and use this - mute the others
• QT version

Seemingly random 8-bit audio files

We're running into several instances of files apparently changing from 16 to 8 bit. We can work on a project with 16 and 24 bit files without any issues. Then, occasionally, when reopening the same project, several files from a project become unplayable. We receive a message that "Logic found 9 files in 8-bit format. These files cannot be played".
We have not found any logical reason for this happening. No common threads between occurances. We ran into this several times a month ago. Then we were fine for a month. Now we just started seeing these errors again.
Is there anything that can be done to prevent this?

Hi jonboy:
Welcome to discussions!
iMovie needs 48KHz/16-bit audio. Anything else will cause you problems.
is it possible for you to send the original footage to a DV Camera set to 16-bit audio and then re-import to iMovie?
