MAstering nested sequences causes audio pops

I've noticed that if I apply dynamics and denoiser to the master audio channel of a sequence, and then nest that sequence within another sequence, when I export the movie (DV AVI) the sound has pops in it. The only way i've been able to get rid of the pops is to take the dynamics and denoiser off of the individual nested sequence and instead apply them to the master sequence (that contains the nested sequence). Bug? Any ideas why this would happen?

I've also had some weirdness like that such as bizarre volume changes in the master sequence that aren't in the nested sequence. Several "quirks" I've encountered were remedied by re-rendering or deleting the preview and media cache files then re-rendering.

OS 10.4.10 Update Causing Audio Popping (AND HUM) Issues:

OS 10.4.10 Update Causing Audio Popping (AND HUM) Issues:
The problem on my Intel Mac mini with external Klipsch speakers (two mid-range/high and a subwoofer) is REAL obvious as the system emits a hum like a Spinal Tap amplifier turned up to #11 when 10.4.10 powers down the audio circuitry
Then, if I play a song in iTunes, it first pops and the hum disappears right before playing.
Quite annoying. I restored the mini from a recent backup to 10.4.9. Problem gone.
I'm glad I test updates on the mini before applying them to my Intel iMac 24. I guess I'll just hide & watch what happens before doing any more updates.
Here's what I sent to Apple tech support:
Guys/Gals (OS X Engineers):
Concerning the Snap, Crackle Pop Audio problem in the 10.4.10 update:
Please. Just do the right thing and fix the audio.
There is no need to power cycle the audio subsystem to save .0005 amps on the laptop line.
And then to make your Mac mini/iMac/other desktop users have to put up with it when using AC power is ridiculous.
Put the audio subsystem back like it was in 10.4.9 and let the laptop battery freaks looking for mini-amp savings get a "work-a-round".
Crikey!

Libby,
Backup is unable to make a restorable by Disk Utility backup. You can restore pieces of the software as outlined in my FAQ about backing up user data:
http://www.macmaps.com/backup.html
But to be able to restore a backup with Disk Utility, you need a cloning utility to have made the backup.
I suggest starting a new thread here, where someone else could help you out better:

First off, you'll get a wider audience who may be able to solve your problem. Secondly, responses to you won't confuse the original poster with solutions that don't apply to them. And thirdly, you'll know for certain whether or not a response applies to you.

Multicam edit from nested sequence -- no audio?

Can someone please help me explain why I can change the video tracks as if they are multicam in my nested sequence, but I can't change the audio?
I created a sequence called "sync" which basically is all of my cameras, each on their own individual tracks, sync'd with each other, as they turned on and off throughout the shoot.
I cut this 'sync' sequence into my main timeline 'master', and then enabled multicam. I can now beautifully cut between cameras using the 'multicam' window and clicking on the preview of the shot I want as it plays. I've made my visual edit, but now I want to go back and choose my audio tracks, which it seems I can't do...
Furthermore, it seems that my nested sequence, which has video cut into V1 and audio cut into Stereo track A1, is only playing stereo track A2 from 'sync' when it's played on 'master'. It seems to be somewhat dependent on the tracks I have enabled on 'sync', but not entirely:
1) If all audio tracks are enabled on 'sync', only A2 will play from A1 on 'master'
2) If all audio tracks except for A2 are enabled on 'sync', no audio will play on 'master'
3) If only A2 is enabled on 'sync', only A2 will play from 'master'.
Is there any documentation about this behavior? Is it a bug? Is there any way to select a different audio track from 'sync' from the multicam edit window?
Thanks in advance!

OK, maybe I should clarify...
Only A2 is coming through, NOT A1 -- so that's inconsistent with what you're saying. I have not checked Audio Follows Video, because that's not the bahvior I want. I'd like to be able to choose from any of the video tracks. Is that not possible in Premiere Pro?
Also, do you think it makes a difference that I'm 'multicam editing' from a regular sequence (with multicam enabled) as opposed to an actual multicam sequence?
thanks for the help.

Fade effect causes audio popping

Hello,
I have had a recent issue with iMovie which is only getting worse. Whenever I use the video effect of either fade in or fade out, there is a popping sound which get written into the audio track.
I have tried various fixes but nothing seems to work. It started out as a few quiet audio pops, but now is completely warping the audio. Any ideas?
Basically I have had to go through the painstaking process of extracting the audio and then fixing it in Garageband. This works, but is tedious and takes about 4 times as long. Since I have quite a few clips to process in this way, I need to fix this issue. I really appreciate any help that others could provide with this.

If anyone else has this problem - you fix it by making sure you pan the audio to the center, not left or right.

Getting bad audio glitches on crossfades in nested sequences

I believe I've had this issue a long time ago in a previous version, but I'm now experiencing it with CC2014. Audio crossfades in nested sequences are causing really terrible glitches. Sometimes, popping and crunchiness and sometimes just acting like the crossfade isn't even there.
Anyone else having this issue? Any suggestions on how to fix it other than putting all of my audio on separate tracks and keyframing the fades?
Thanks.

Mac Pro 10.9.4
Premiere CC 2014.0.1 8.0.1
This occurs all around my timelines, without rhyme or reason, sometimes here or sometimes there. Does not appear in exports, just within the timeline as I edit and play, scuba, etc.
Sometimes a specific transition or crossfade will glitch, sometimes it won't.
I tried to remove the transition, and it still audio glitched, ** even before I added keyframes. Oddly, this this is happening ONLY on the clips that the transitions were on, and NOW, if I take there transitions off, the glitch is happening on different points within the clip, not just at the transition point.

Nested Sequence Audio Problems

Hi all,
Progressing with FCP and experimenting with doing things differently, I am trying to take advantage of being able to nest sequences so that the minor changes I make to these individual sequences automatically update in the large, full sequence in which these various scenes are nested. It's great.
However, I have encountered a couple of different problems with audio. For instance, at various points, when I am playing the full sequence (the one containing nested sequences), audio drops out completely (though only briefly). At other times, an audio track that I have faded out pops back on for no reason.
Does this ring a bell with anyone?

I have never really had any luck nesting sequences in FCP. When I first bought FCP, version 1, I was sold on the premise that FCP has about 90% of what After Effects has in it. It does not. FCP is a video editor and not really designed to nest sequences like a AE. I like Motion because it can render internally in FCP instead of AE that requires you to render to a media file and then import that into FCP. I hate to tell you that you compositing is something best reserved for a dedicated compositor. Doing it in FCP will only make you cry.

Nested Sequence Audio Update Glitch

This problem seems to pop up on my system from time to time and I can never remember how to correct it.
Nested Sequence plays back with an audio track that is no longer in the nested sequence. When I open the nested sequence, sure enough, the audio track is not there.
I've tried "refreshing" the track as suggested by another thread by way of control clicking and removing none existant attributes. It didn't work. I've tryied adding Audio Filters that will require a render. It didn't work. I've tried deleting all of my audio render files. It didn't work. I've already resorted to overwriting the nested sequence in question with the same nested sequence, but there should be a way to fix this @#$% bug without doing that!
Ideas?

I apologize to anyone reading this for the negative tone of the post above.
I have since answered my own question and, as usual, the problem turned out to be one of my own making. I'm pretty sure that the reason that none of the other methods worked for getting rid of the glitch was that I had pulled the nested sequence in question out of a different project altogether and added it directly to the time line rather than adding it first to the bin of my final project and placing it into the timeline from there.

Audio mixes not correct when inserting nested sequence.

Ah, yet another anomalous behavior issue...
I commonly edit packages for a program I regularly work on, then drop the nested sequences into the show timeline...it's easier that way, and the EP likes it that way. However, I occasionally come across an issue where the nested audio sequence doesn't "remember" the mix levels of the component parts. For instance, I just made an audio adjustment to the open of the show, and dropped the nested open into the show timeline...where it promptly "forgot" the music rampdown I'd just done.
The workaround? I slipped the audio track, blowing out the render files...then dragged the clip back into sync, re-rendered again...and then the mix stuck.
Probably I should do this sort of stuff in Soundtrack, eh?

FCS has lots of quirks (I hesitate to call them bugs because they are not always repeatable). Still, people need to keep in mind that the FCS suite is built upon an ancient (in computer years) core technology (and code). While everyone is holding their breath for 64bit thinking it will be faster, I'm cringing because I know what a massive bit of code this suite represents and the thought that a complete rewrite will get everything correct is simply unimaginable.
[/rant on] My simple hope is they do not keep chasing after these consumer formats (including BR) and simply focus on making the core of the program function exactly as it should - especially media management. The whole 32bit/64bit nonsense is a distraction. Stuff that is stable and works the same every time - even if a little quirky- is MUCH more valuable in the professional environment than dumping in loads of new stuff. [/rant off]
Have fun.

Nesting Sequences (Audio Tracks Problem)

I am trying to use Premiere to make a rough (rough!) edit of some audio. There is no video yet.*
I made a handful of sequences in Premiere, all of which consist of edited audio clips.
Now I have created a new big sequence, and I want to nest the audio sequences in this new big sequence. (I only want to bring in the audio, if I can do this easily.)
When I drag the sequences into the new big sequence, it keeps dumping the audio on Track 9, which didn't exist before.
How tough will it be to put the audio of the nested sequences on Track 1?
*Animations will be made later in After Effects and added to the timeline to go with the audio. Until then, there's no video.

Your sequence setup is messing things up. Audio tracks are either mono, stereo or 5.1. If you have only stereo tracks (indicated by the two speaker icon at the left side of the track), they can not be placed in a mono or 5.1 track. If a stereo track is missing, one will be created for you. Same with the other formats. There is nothing wrong with a 9-th audio track, but you can delete the empty tracks above it easily to move your audio track to the first track.
Basically, you need to adjust your sequence settings.

Nested sequence: after a cut, audio repeats from previous clip

Summary: In a nested sequence situation, I'm getting short audio repeats from a clip element just prior to a cut.
Context:
Premiere Pro CC, latest version at time of writing (7.0.1 (105), under Windows 7 (64-bit).
Structure: I have a sync-sequence (multicam source sequence) consisting of XDCAM-EX (file structure broadly along the lines of AVCHD) and Z1 (plain m2t files). Derived from / dependent on that is a multicam edit sequence, where I cut between camera angles. Then that sequence is itself nested in a master sequence (showing selected extracts of the performance).
For reference purposes: Multicam edit sequence consists (among other things) of a rock band's "big finish" followed by some applause. I made a cut in the audio part (only) of the nested sequence clip, to enable the audio for the applause to be normalized independently of the band performance. To smooth the join I added a crossfade transition over the cut. Nicer in principle than using volume envelopes.
When I play the original recording or the multicam sync-sequence or the multicam edit-sequence, all looks and sounds fine.
Problem:
When the Master sequence is played back (in preview or an exported/encoded clip) I hear the big finish, then applause starts, then after 2 seconds the "big finish" is heard once again, but at lower audio level.
This effect happens wherever I have used the same cut/normalize/crossfade technique in the (nested) multicam edit sequence. I have also encountered it in previous projects in Premiere CS6.
If I delete the crossfade then the problem disappears... Doesn't matter what type of audio crossfade is used.
Is this a known problem? and is there a quick workaround? (other than using envelopes instead or copying/patching the audio up to the master level)

Ah so [Sequence > Render Audio] is not just a "luxury item" to get waveforms to display when nested or to (presumably) to lower CPU load (e.g. when audio effects have been applied). It's something that I will need to always do from now on... It's a shame there's a "feature" but great to know of the workaround.
Thank you very much.

Garageband Audio Pop Causes Silence

Hey Guys,
This is my first time visiting, so forgive me if this error has already been addressed in previous posts. I've been having a really annoying problem with GarageBand lately. Every so often, the when shuttling through a track that's playing, I'll hear a loud audio pop and my audio card will completely stop working. I have a USB receiver/speakers that I plug in from time to time, and they do the trick as a temporary workaround, but eventually GarageBand even crashes them. The silence is across all other programs as well, and the only fix is a restart.
Is there some sort of failsafe within GarageBand that causes the audio card to disable when it hits a certain dB level? Am I doing something stupid? I might add that I recently installed the YMCK magic 8-bit plugin and that will do the same thing as soon as I select it as a voice for a software instrument. Suffice it to say, I don't use that plugin anymore.
Any ideas what might be going on here?

I've been searching all around, there doesn't appear to be a user fix, or a fix from Apple. I hope it is fixed in Snow Leopard.

Why does my nested sequence have only one channel of audio?

Hi,
Working in Prem Pro CC on my Mac Pro.
I have a number of interviews, each shot with 3 cameras and with audio from a separate audio recorder. The audio has two channels, Ch1 has the boom mic and Ch2 a radio mic.
I created a sequence, placed the audio into channels 1 & 2 (they are linked) before placing the video tracks onto timeline tracks 1-3. Everything's synced nicely and so I nested the shots and then I enabled multicam on the nested sequence.
However, now when I edit the nested sequence into my edit sequence, it has only one channel of audio. I tried Modify>Audio Channels but within that page, in the option to select 'Source Channels' the options are "None" and "Channel 1".
How do I get my nested sequence to place both audio channels into my edit sequence?
Any help much appreciated.

Nevermind folks, I figured it out. I had my render control settings set to Apple Pro Res on some timelines.

No Audio in Master Sequence with nested sequences

I have tried searching for a solution but cant find anything the same as this.
I have several sequences with multi track edits in them (not multi camera but on diffeent video and audio tracks)
I have dropped these sequences into a master sequence, they line up perfectly, but when I play them, the video is fin, but there is no audio. the individual sequences have audio without any probelm.
I have not done any audio editing in the sequences yet, just assembled the visual edit with the orignial audio tracks attached.
I klnow I must be missing a step or doing something wrong, but can't figure it out!
thanks

Not muted. All plays well in Source Monitor but dragging from Source to Timeline only brings video. Same for dragging from Project to Timeline.
This morning I tried "New sequence From Clip" on a sequence from the Project Window. This works but then requires an extra step of copying from the newly generated Sequence to my "Master" sequence. Intuitively it seems like the other methods should work. I should be able to Import project files containing all the required sequences and then from the Project window drag each of those sequences to a master timeline. Am I incorrect in my assumption on this workflow?

Nested sequence: Audio anomaly

I've had the strangest experience. I created a number of nested sequences in my project. These sequences included a video track, a dialogue track and a music track. I played through these nested sequences and everything seemed good to go. I saved the project and quit out of PremPro. Today when I opened up one of the nested sequences the music track has been somehow partially "switched" with another sequence's dialogue track. The music is no longer on that track! (I am working on a mac os, snow leaopard with CS5.5). what did I do wrong?

I apologize to anyone reading this for the negative tone of the post above.
I have since answered my own question and, as usual, the problem turned out to be one of my own making.

After encoding a sequence, music audio (Track 1) is fine, but speech audio (Track 2) is sped up and crackling.

Hello forumites,
So I've run into an odd problem I haven't experienced before. I exported my docu film last night. I have my music audio on A1 and speech audio on A2 in the timeline. When reviewing it, the music audio plays back fine, but the speech audio is playing back slightly fast (resulting in a bit of a chipmunk effect) and it's crackling (possibly because of the speed-up). The video appears to be in sync with this weird speed-up.
I'm using Windows 8.1 Pro and the latest version of Adobe Premiere Pro CC. Although this is happening on two different systems, here are my computer specs.
PC 1:
Custom built desktop
CPU: FX-8350 4 GHz
Motherboard: ASUS Sabertooth 990FX R.2
Memory: 16 GB DDR3
SSD: 256 GB Samsung 840 EVO (Primary)
HDD: 2 TB WD Red (Data)
GPU: 2x Radeon 6950 (CrossFireX mode)
PC 2:
ASUS G53S laptop
CPU: Core i7-2830QM 2 GHz
Memory: 6 GB DDR3
SSD: 120 GB Crucial M4 (Primary)
HDD: Seagate 500 GB (Data)
GPU: GeForce 460M
I did a bit of troubleshooting and thought that perhaps I nested sequences too many times. So, I did a few test renders from the ground up on each sequence where the nesting gets deeper. I got up to two nesting levels (where one sequence has a nested sequence which contains a nested sequence - Sequence-ception ) with all audio rendered normally.
However, the next nesting level resulted in the audio issue. So, I copied and pasted the timeline from the previous sequence to the current sequence, overwriting the nested timeline. Oddly enough, it still caused the problematic audio, which has me thinking that it's not related to nested sequences after all.
Keep in mind that playback inside Premiere works fine. I even created a new sequence from scratch into which to paste the timeline. Also, encoding using different codecs didn't make a difference. Of course, I also did the basic things and updated my video card drivers, restarted my computer, uninstalled/reinstalled Premiere Pro and Media Encoder, and tried encoding without GPU hardware acceleration.
Here are some 5-second DNxHD renders to get a grasp of what the results are.
Double Nested: https://www.dropbox.com/s/0xp50qbm48gjupd/Double%20Nested.mxf?dl=0 (Good audio)
Triple Nested: Dropbox - Triple Nested.mxf (Bad audio)
I should probably mention that I configured symbolic links to remap the Users folder to my data drive, as that has been known to cause some problems with Windows, but I made sure to link all the assets in my project using the actual file paths rather than the symlinks. Also, I've been rendering other projects prior to the previous patch with this setup and didn't experience any issues.
Has this happened to anybody else as well? I did some searching for this issue but I'm apparently the only one. I'm just hoping this is some weird bug introduced in the last patch.

That may be so, but why even have that feature if one can't even take full advantage of it? I'll be asking Adobe that if I don't get many suggestions or input here.
Thanks for responding, though!
