Audio Preview Problem

I'm capturing a bunch of video and want to preview the audio at the same time. The Preview works fine until I push the "Log Clip" button after setting the in and out for my first clip, when I resume playback the audio goes all sketchy. It still plays the audio but it's intermittent... plays for half a second then stops, then plays, then stops, etc. If I uncheck then recheck the Preview checkbox it works fine again.
It's regular SD video off of a DVX-100.
Anyone know a solution?

Playing the audio during capture requires a fair amount of system overhead and your computer isn't cutting it (Who knows why - that's a different issue.)
To keep track of what's on the tape, run the analog out from the camera to a NTSC/PAL monitor and speakers.
Good luck,
x
in the fwiw category, your camera records DV. SD is 720x486 and requires a dedicated capture card.

Audio preview no longer works correctly since AE-CC update

Hi everyone.
Since updating AE CC a couple of days ago (now on 12.1.0.168) on OSX 10.8.5, 2.7GHz i7 16GB RAM, the audio and RAM preview no longer functions correctly.
The steps I follow are:
Open AE
Open project
Press . to preview audio from where I am on the timeline, OR RAM preview workspace
What happens is my cursor turns into the wheel of doom for a about 20 seconds, then the playback begins but the audio is sped up which is wrong. Video is correct speed.
If I stop the audio or RAM preview, then preview again, everything is fine and plays instantly. If a RAM preview loops, then the audio reverts to normal speed.
I can open up any and all of my different project files and audio previews perfectly and instantly as it should. It's just the first time I press the . key on a freshly opened instance of AE that I get this problem.
I've tried restarting my mac to no avail, and also changing the pref settings away from what the settings have always been and that doesn't work either. I've even trashed my prefs and that also doesn't work.
I work exclusively at 25fps. Frame rate for RAM preview is set to auto (25) and changing this from auto to 25 doesn't work.
Memory settings are default since trashing my prefs, 16GB installed, 4GB for other apps, no checked boxes are ticked.
Any ideas on what has happened please?

AE CC 2014 audio preview speed up error... "chipmunking" randomly

I"ve been having an issue where the audio during a full RAM preview with video or even if it's just audio preview (no visual) will play sped up. Sometimes it will speed up after having previewed correctly once, but every subsequent time will result in "chipmunking". This has happened on two different workstations.
These are wav files for the audio. The framerate is correct in the preview window.

Using internal audio outputting through the headphone jack
Wave files are 96 KHz / 24 bit
The problem is not consistent. And there was a new development: It also played slowed down at a lower pitch during one amusing preview.
Maybe this is an OS X error when other sound programs are used and then quit, and the machine had to play different types of audio specs. I also use Soundtrack Pro for quick audio editing and Pro Tools for heavy sound design. But both of those programs playback audio correctly 100% of the time.
At this time, I had quit every program and left the computer for the night (but not a restart) and now it appears to be previewing correctly. But the odd thing is that this was happening on my laptop (same specs for the OS and software) in front of a client the other week (hitting the full RAM preview resulted in accurate video, but fast, pitched up audio that ended before the video since it was pitched up)
This problem does not extend to renders. Only previewing.

Rendering Hundreds of Audio Previews Upon Export, Long Render Times

Hi everyone,
I have an assembly cut of a feature, with footage and a timeline at 422 ProRes HQ, 24 fps, 96kHz audio.
When I try to export any length of a clip, I get exorbitant render times and hundreds of audio previews to render.
Video alone is rendered almost instantaneously.
There are some audio files on the timeline (music and SFX) at 48k sample rate.
Any ideas what the problem is?
Thanks.

Thanks, Ann. I'm thinking that may be a factor because this is the first time I've had to work with audio recorded at 96 and I've never had this problem.
Can anyone else elaborate more?

CS4 audio sync problems

Hi all,
sorry if this question is old hat - I've searched the forums and can't seem to get a clear answer (most refer to CS3 and before) so thought I'd ask anew.
My preview in Premiere CS4 is fine, as is the preview in Encore CS4. The video was captured from four tapes (HD as mpeg and SD as Matrox AVI) in Premiere. The final DVD (10 minutes) consists of 21 clips. All but one are OK - this one has the voices well out of sync with the video, even though other clips taken from the same tape are fine.
I also had a major problem recently with an MP4 from youtube, which I guess is the same issue - everything else was fine, but this one clip was well out.
I'm guessing by now this is an old problem. What's the solution, please?
Thanks
Paul.

Newbie to Adobe here ...
Okay, so after spending over 14 hours trying to fix the audio sync problem I fixed mine. After editing my project I selected Sequence > Sequence Settings > Playback Settings > under Realtime Playback make sure the "Desktop Video Display During Playback" box is selected. Next, in "External Device" change the setting from "None" to your next option. Mine reads DV: 29.97 720 X 480i. Next, Under "Export" section in that same window select the in "External Device" select the DV option again. Also, you might want to "Disable video output when in background" ...select that box at the bottom of the screen.
Now, try recording the video to the tape ....my audio now sync's as normal. I hope it works for you.\
One more thing ... you can keep the "Desktop Audio" button selected.

CC Update - now Audio Preview Freezes up

Been working fine with CC2014 version - updated yesterday.
Now when I'm working in After Effects and go to do an audio preview - the first time it works fine, but the second time I do a preview I get a spinning wheel and nothing. Windows Task Manager shows After Effects using up 12-13% CPU (which is 1 thread as I have quad core with hyperthread).
I am using 96kz 24bit audio files -but it was working just fine in the previous version.

Distorted sound with audio preview

Hi,
I have a problem with the Finder file preview. As for sound files, one can usually listen to songs within the file preview, without opening an application. But since recently, the sound of this function is very loud and distorted. I had been running two such previews at the same time and suddenly the sound turned to this.
Since then it has stayed this bad. I tried the usual means: restart, clear user caches, repair file permissions, p-ram reset ... nothing of this helped.
The funny thing is: All other audio stuff works fine. I can listen to iTunes, use QuickTime - everything is fine. But as soon as I try to listen via the Finder preview, the sound is terrifying.
Does anyone know any help to this, please?
Many thanks in advance!

Open the Script Editor in the /Applications/AppleScript/ folder and enter the following:
tell application "Finder"
quit
end tell
delay 1
tell application "Finder"
run
end tell
Don't press the Run button until instructed. Next, open the /Library/Preferences/ item of your home folder, and move the item com.apple.finder.plist to the desktop. Once this file has been moved, run the script, and then use the audio preview option again. If the sound is still distorted, move half of the plist files to the desktop, run the script again, and repeat the procedure until the item causing the problem is found. If nothing in the /Library/Preferences/ folder is causing the issue, continue with the other items in the home folder except for the desktop itself. If you determine that an item isn't causing the problem, you can put it back where it originally was.

AUDIO SYNCH PROBLEMS

I have never had an audio synch problem 'til now. I am running 10.5.7 on a 2.8 GHz Intel Core 2 Duo 4 GB ram, 24" imac.
iMovie 6.0.4
I have a 50 minute heavily edited project with many transitions, etc.. I have no problem with the footage downloaded from my Sony HD camcorder. I even saved many individual frames as pictures and changed them to the beat of the music in the timeline and all worked perfectly. BUT, my problem is with the "video trailers" I slipped into the timeline. The audio slips when I play back in the timeline AND when burned to DVD. BUT, it does not slip in the same place every time I preview it. If I scrub the playhead back over some of the bad scenes and play them again, they are in synch. IT KEEPS CHANGING..... When I export to a desktop movie to review - the synch problem is there and some of the audio is missing. This only happens on "movie trailers" I have downloaded.
I can't figure out why it keeps changing in the timeline and then correcting itself when I back up and play it over again. I AM GOING CRAZY........
Thanks in advance for any suggestions.
Wally

Thanks for the reply but my problem is not with iDVD - it is with iMovie - when I add "trailers" to it they go in and out of synch at different places everytime I review it before moving on. When I scrub back over the problem area and then play again, they are perfect for one time and then I try again and they are not synched. The problem is in iMovie.
Thanks,
Wally

ProRes to Blu-Ray H.264, then Preview problems in Encore CS5

Hello all,
I've been taking 90 minute or so ProRes 422 QuickTimes (29.97 interlaced) into Media Encoder CS 5 and creating H.264 Blu-Ray files for use in Encore CS5. I'm using the 1080i maximum quality setting and adjusting it so that target bitrate is 25mbps and max is 30. Also doing 2-pass VBR.
The issue I'm having is when I import these files into Encore CS5 and then preview them in a timeline they are artifacting all over the place. They look like my cable signal when it breaks up, except through the entire program. I've re-transcoded in the Media Encoder and am having the same issue. I've also tried transcoding within Encore (which is really the same thing), and still it persists. I haven't made a BD-R yet to check that and I know the preview in Encore CS 5 is very buggy. But I'm wondering -- has anyone run into this? Is this just a preview problem, or is there something actually wrong with the transcodes?
Also, if anyone has a tip for where I can open the *.m4v files coming out of Media Encoder so that I can check them somewhere other than in Encore that would be awesome. VLC player doesn't work, neither does QuickTime. Thanks everyone!
Best,
JD

Jeff,
Thanks for the response. Here are the answers to your questions:
Some obvious but necessary checks:
Are you authoring in a Blu-ray project and not a DVD project? YES, it is a 1080i 29.97 Blu-Ray project.
Are you checking the transcode status column for Blu-ray and not DVD? Definitely looking at the transcode status for Blu-Ray, and not DVD.
If all is OK with those checks, then please check the audio:
Are the files multiplexed? If so, try elementary streams.
Are you using elementary streams? If so, try multiplexed.
On these notes -- what is a good way for me to know if the transcoded files are multiplexed or elementary? The interesting thing is that when I bring in the M4V and WAV files into Encore from what AME creates, the WAV file does NOT require transcoding, but the video file (M4V) does.
Regarding the preview issue I was having it's worth noting that when I checked back in preferences the playback quality was still set to DRAFT, as if when I switched it to HIGH it just didn't take (and I tried this more than once). I put it to HIGH again today and this time it seems it took, as preview playback quality is good again. Just seems strange to me that Encore has a mind of it's own sometimes with certain things.
I'm really more concerned with the transcoding at this point. I did a project a couple weeks back where I just bit the bullet and transcoded the M4V again in Encore to author the ISO file, and several chapters of the program came out stuttering on the disc. The original Quicktime source is fine and the preview playback on it was fine during those chapters. I can't seem to find a throughline for these problems -- just seems to happen every now and then and can't control it.
I authored a 53 minute 1080p 23.98 disc in early January that worked beautifully. Everything was great - no problems.

After Effects CC audio mapping problems

Whenever I start After Effects it seems like it takes over control of my system audio output settings.
For instance if I am listening to a song on iTunes and then start After Effects, I will only hear iTunes when AE is active from then on. Audio preview and scrubbing in After Effects works well, and all other audio works as they should but only when using After Effects. If I switch back to iTunes it goes silent. This goes for all other audio on my computer.
To get the audio back I need to go into system preferences and swich back and fourth in my settings. But if I then go into After Effects again the problems are back. It feels like After Effects hijacks my system audio setting when it is started. Is there a way to prevent this from happening?
I am running After Effects CC 12.2.1.5 on OSX Mavericks.

Hey there, I'm having the exact same problem (Mavericks 10.9.1, AE 12.1).
I use an H/K AVR 165 with 5.1 as my default audio device (HDMI). Are you using HDMI as well? Because every other connection works (cinemadisplay speakers, optical), only when I have HDMI as my default the remapping occurs.
Waring: don't try to pick After Effects (12) or Premiere (7) as default in the sound-options in osx preferences (not the MIDI device, the aactual sound output in the preferences), I tried this yesterday and at first I thought it worked (I picked Premiere, I was just testing and curious) but as soon as I started Premiere, the whole system crashed and i needed several safe boots to get my Mac working again (it froze right after the login).

The project label now carries signal with yellow triangled exclamation “i tunes out of date”.
To solve the sync problem I’m following advice and detaching sound from all of the 100 or so short clips. This operation has been stalled by the spinning ball. Shut down restart has not helped.
The Project is mounted from Iomega and superspeed ext hd connected to imovie09 on macosx 10.5.8.
What to do to resume repairs to the audio sync problem and so successfully share for youtube upload?

CS4 Audio Export Problem

Hi
I'm fairly new to CS4 and have picked up an audio export problem, more than likely with a setting of sorts. For some reason when I export to MPEG2 -DVD via the Media Encoder, the video portion is fine as well as any audio that has been placed and edited on tracks audio 1 and 2 in PP. However, if there is additional audio placed on tracks 3 or 4 for example (say a music MP3 overlay) then this does not come out ... only audio placed on tracks 1 and 2 in PP come out. I have checked the obvious like making sure the tracks aren't muted etc but to no avail. Also tried changing from PCM audio to MPEG ... Stereo to 5.1 mixdown ... nothing doing.
Any help would be greatly appreciated.
Thanks and regards

Thanks Harm ... got SnagIt and with a few helpful YouTube tutorials ... am in business. Hunt and John, also thanks ... the other method equally as good. Now, I have attempted to attach my screen shot which should display my CS4 timeline and associated audio monitor windows above. By the way, this was for a wedding and as indicated, you will notice an MP3 lying in audio track 3 which as mentioned is my problem as it is not audible after render via Media Encoder. But remember, the moment I slip this MP3 up into audio track 1 or 2 above ... problem solved. I know there must be something small like a setting gone wrong or incorrect. As mentioned, any help would greatly appreciated.
Thanks to you all.
