Rendered Audio Repeat Glitch

[L4RRY_57]

We are encountering a glitch in our media output after our recent Premiere Pro CC 2015 Update (installed 12/16/15). The exported media will fill empty audio portions with a repetition of the last 1.5 seconds of audio until a new audio clip in the timeline plays. I am also experiencing the output media with an arbitrary amount of blank footage added at the end. I've checked the timeline to make sure there was not any "straggler" clips hiding at the end. One 10 minute video exported as an hour and a half. We are exporting both through Media Encoder and Premiere.

I had exported a 20 minute movie before installing the update on my system into several formats without issue (H.264 MP4, MPEG2 Blu-ray). My co-worker had already installed the update and was encountering these issues exporting the same file. We didn't realize that the update could be the cause. So I installed the update afterward and am now noticing the same issues when I export files. We are both using new 2015 Macs, Yosemite and El Capitan.

Assuming this is a result of the Update, I'm wondering if anyone else is encountering this issue. Otherwise, I suppose this is more of a report than a question, unless you have a solution for me. Our temp solution is to fill the "dead" audio space in the timeline with low audio slugs.

We saw this same issue yesterday. Strange audio repeating itself during empty spots on the timeline.

We haven't seen the issue of adding extra time to the timeline yet,though.

Setup sounds similar...2015 Mac with El Captian.

Thanks for mentioning your work around!  Saved me time and frustration though I probably should've thought of it on my own!

[rachelb64811100]

I am having this exact issue, any resolution?

[Jim_Simon]

any resolution?

Read post 2.

Same thing.  I have noticed the that same 1.5 seconds of repeated audio upon export.  I was only noticing this at the end of the sequence.  My solution when reexporting has been to add 5-8 secs of of black slug at the end of the clip.  Now I am noticing it at points within the edit that have blank spaces.  That is not acceptable.  I am going to have to insert a slug into every section of the timeline that doesn't have media associated with it??  That's nuts!

I have noticed this problem on my work iMac that was running El Capitan but not on my home iMac running Yosemite.  Both have updated PP CC 2015 to v. 9.1.0

***one more side note I have noticed with El Capitan and not Yosemite is when I attempt to grab a clip in the timeline and move it, the clip jumps down 1-2 video layers in the timeline which can really screw you up if you're not paying attention.

Yes I am experiencing this problem. Client is furious...

It only started happening after I upgraded to latest version. Last week to import AfterEffects Sequences.

Wish I hadn't upgraded...

Got the same problem, exporting 30 sec. section, after upgrade Premiere from 9.0 to 9.2.

Exporting direct from Premiere it doesn't happen. But, using Adobe Media Encoder, happens.

I thought this problem was related with xml, but doesn’t. DaVinci Resolve and After Effects read the same xml with no problem.

The solution, until now, is put an audio with 0db when master audio is going down, until the end of range.

Sorry, not 0db, volume 0 I mean.

Better, do the Adobe Media Encoder Upgrade, version 9.2.0.26 solves this Bug.

[Jim_Simon]

version 9.2.0.26 solves this Bug.

It hasn't on my two machines.  What does solve it is checking that Import sequences natively box under Preferences.

[Chris Meyer NM]

Unfortuantely, I am still experiencing the repeated audio bug with 9.2.0.26.

Using AME 9.2.0.26 (2015.2) under OS 10.10, when there is a gap in the audio in my Premiere Pro 2015.2 timeline, AME likes to fill it in with a snippet of adjacent audio. So I get a lot of repeated dialog and the such. Happens on two different computers, even after re-installs. Happens with h.264 wrapped as .mp4 or ProRes wrapped as a QuickTime.mov. 100% repeatable.

If I render the same timeline out of Premiere, it's fine - no stuttered audio.

I have 38 sequences to render, so having to wait for one to finish before starting the next one to render is a HUGE productivity killer - I have to baby-sit the machine for several hours, rather than being able to queue up and render in the background.

Not impressed, Adobe. Between this and failing on dynamically linked comps from AE, claiming "media offline" for one comp whereas another in the same AE project and Pr sequence renders fine...not at all happy.

Hi Chris,

It's a known issue. We've got a fix coming in the upcoming version. See if any of the above workarounds assist you. I'll try and put together a knowledge base document in the mean time.

Thanks,
Kevin

[Chris Meyer NM]

Hi, Kevin; thanks for getting in touch -

Unfortunately, the suggested workaround of the native sequence preference, and updating to 9.2.0.26, did not fix the problem for me.

I've not tried the export-audio-then-reimport fix because in my case, I have 38 short (average 6 minutes) sequences rather than one long sequence, so the time spent doctoring 38 individual sequences ends up not being as "efficient" (the concept is relative) as babysitting Pr exporting each sequence in the background while I try to get other work done. If it's important to try that from a beta-testing or bug-hunting perspective, let me know.

I've filed a few other bugs (through the public form) with Premiere was well that came up during this project, such as previewing issues when crossfading between two different pan-and-zoom settings on the same 4k source in a 720p timeline; I also have a bug logged several weeks ago with the Ae team concerning the "media offline" issue with AME, Pr, and a dynamically linked Ae comp. Between those and now losing a day due to the AME bug (which appears to a have been around for at least 2 versions), unfortunately I've not come away impressed with the "suite" approach to using Ae + Pr + AME. Or just using Pr solo. When previously-working features are broken by updates, there needs to be a more proactive approach to downgradin users to working versions so they can get work done and not miss deadlines.

thanks -

Chris

Hi Chris,

Sorry for your continuing troubles. The workarounds do sound quite painful. I brought up this topic with the engineering team and there's nothing we can do prior to the upcoming version on that issue. Very sorry about that.

All you can do is file bugs as you have and I hope things will go smoother for you in upcoming projects. I hope to provide more info on how to avoid some of these issues and how to streamline processes.

Thanks,
Kevin

[Chris Meyer NM]

Thanks, Kevin.

(You'd be amused to know this project is a video training course on modular synths - yep, I'm getting back into that world, 25-30 years later...)

We're experiencing this as well. Glad to hear it's on the radar.

[Spacecat66]

Upgraded to the newest versions of everything today (2015.3) and the repeating audio glitch persists in Media Encoder when outputting an MP4. Yes, rendering from AE or Premiere is a way to get a render without the glitch, but it's not the ideal solution for my workgroup. We're still anxiously awaiting an update that fixes this problem that has persisted through many product updates.

So that we can continue to use Media Encoder with our workflow, we fill any audio gaps in the timeline with audio set to negative-infinity or (-192 in AE).

[dylanwaters]

Having the same issue. Does it override the ending portion of audio with about 1.5 seconds of previous audio?

[dylanwaters]

And I should also add that I have never encountered this repeat glitch until after this update.

[FocusPlay_Studio]

I can concur that the 2015.3 update has not fixed this issue. I am not able to render using Media Encoder without getting a glitch in the last 1.5 sec of the audio. Currently, I have to render a Quicktime MOV with AE or Premiere then re-render in Media Encoder to MP4

[Chris Meyer NM]

I've not tested this myself yet (busy with AE), but I see Spacecat66 just reported it is NOT fixed in the 2015.3 release. Can you verify either if was supposedly fixed, or if it has a date on when it is actually supposed to be fixed? Worried, because the next planned major release is probably a ways off....

[Jonathan_Joosten]

has this been fixed yet?

[johnt19662173]

I’ve just wasted over an hour on this problem (Media Encoder 2015.3
/ PC).

A workaround for me (so far…) has been to extend my AE comp by 2
seconds, with nothing on this extra bit of timeline. Then just render the work
area up to the actual end of the project (IE. where the timeline originally
ended.)

I think this may be a re-phrasing of other people’s workarounds,
except that I didn’t have empty audio at the end of the project, but encoder
was still looping back the last second or so of the soundtrack. 

Hope this may help.
