Rendered Audio Repeat Glitch

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.

Correct answer Kevin-Monahan

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 -

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

Hi people. This tread here is signed as SOLVED. Nobody from Adobe visit this tread since marth 2016. That is why I opened a new tread here: Audio Repeat Glitch by rendering per AME 2015.3 10.3.0.185 Welcome to the new tread.

I didn’t have this bug until I updated to Premiere Pro and AE 2015.3 this week. Like Spacecat66, happening with dynamically linked AE comps.

Adding the extra 2 seconds in the AE comp, then cutting that off in the Premiere edit works. But what a stupid way to work.

It’s known and admitted by Adobe that AE has an audio bug with AME, introduced in CC 2015.3. They’re under the impression it happens only if you have animated an audio property such as Levels or an audio effects, and were under the impression that it’s intermittent and tended to happen with very short comps - if anyone has concrete experience to the contrary, I’m sure they’d appreciate more data points. Adobe says a fix is in the works. (This happens to be a HUGE problem for me, as I have to update and re-render a few hundred AE comps over the next 1-2 months; having to pause work while AE renders them rather than handing them off to AME to render in the background is going to lose me a lot of time.)

BTW, this bug will probably happen if you dynamically link an AE comp into Premiere, as AME uses a similar mechanism underneath the hood.

SEPARATE from that: Are others still experiencing the Premiere-specific bug with AME where, if you don’t have an audio track running the length of your Premiere sequence, that AME will randomly grab audio from elsewhere in the sequence (usually close by) and paste it into the gaps when it renders? It seems that running a track of silent audio or room tone for the entire length of the sequence is the workaround there.

Yep, I've still got that Premiere-specific bug with AME. For me, it seems to fill in all of the audio gaps with the closest previous audio clip. I'll often have audio gaps between scenes, as my gaps are filled with dynamically linked AE comps without audio tracks (animated transitions)

Add me to the list of frustrated users. It seems to happen when rendering from Media Encoder, at least that's my experience. Rendering directly from AE doesn't cause this problem, but I don't have the encode types that I need within AE's render queue. This bug appeared as soon as I updated to 2015.3. Never had it before. I'll try some of the workarounds mentioned in this thread, but come on Adobe. This is something you guys need to fix immediately. This has already endangered a delivery date.

I've had the exact same experience. Didn't happen until most recent upgrade. Doesn't show up in direct AE render. Tried reinstalling encoder but that didn't help.

If nothing else how can I output a .mp4 directly in AE. This used to be an option but no longer is.

Just wasted hours trying to render a finished Skillshare class because of this issue. Adobe, this is unacceptable! Luckily johnt19662173's workaround solved the problem: add 3 seconds to the comp in AE and then set the in/out points to the desired length in Media Encoder and hit render. But it's really tiresome to do this...

The same thing is happening with my projects going from AE cc 2015.3 13.8.0.144 to Media Encoder cc 2015.3 10.3.0.185

Please can you fix this Adobe its a major pain in the backside.

Just want to add my voice to this. I noticed the issue on AE comps that I'm direct linking in PP. The repeat issue is actually "overwriting" existing audio within the last 2 seconds of the comp. Adding the 2 second "buffer" at the end fixes it, but that is a sloppy workaround, not a solution. PLEASE get this fixed ASAP!!!

I just built a new windows 10 computer, installed all the latest Adobe products and am encountering the same issue with the repeated audio glitch at the end of the spot. I shoot and edit spots that need to be sent to the TV stations. This is a HUGE bug that is ruining my life (and my client's).

Like many of you, I'm adding a few seconds of extra audio at the beginning and end, and taking it over to my old computer to see if I can spit these out properly. What a pain!

I got the same problem with the ghostly repeating of audio in a portion of empty audio area, exporting from Aftereffects/ PC. This happened after upgrading to the last 2015.3 version of Media Encoder. Never had this problem before. None of the above tips worked for me, but only exporting the entire project, including audio as a lossless video via AE and then converting it to H264 via AME. This was the only way it worked for me.

There is no such problem when rendering only that composition separately, but the problem appears when rendering it as a layer in the main comp. Adding only the audio on the main comp's timeline as a layer gives the same glitch - repetition of random words, sometimes just a sort of gibberish. I really hope the engineers will be able to fix this soon.

Here's what I did that worked for me... Add 3-4 seconds to the Composition in AE. In Media Encoder, go into the "Preset" menu and trim off however much you added onto the project. Maybe try testing it with short projects? Hope it helps.

Interesting idea, but the gap in my audio tracks is often not just at the end. The bug effects any space in the timeline of both Premiere and AE where there's an audio gap, and I often have audio gaps all throughout my projects. My rough cuts often go out for review to producers and clients long before the audio guy has a chance to mess with filling in the gaps.

My solution is to render from whatever program I'm working in and Handbraking the enormous render so it's small enough to send out for review. While not too much of a PITA, the fact that Media Encoder should do the trick but has had this bug for a long time across many versions is super annoying.

Same Problem here. And found a workaround.

Dont know if this has been mentioned before. But using Premiere itself to render instead of Media Encoder worked for me.

Hope it helps someone out there.

I find a quick fix is to create an audio slug which runs underneath the sequence - extend it past the out point too before you export.

Thanks for the tip, bamml24196736. I just came across this issue. I guess I didn't have empty audio in any of the other projects I was working on this year. I seem to be able to use any audio file on it's own track and drop the volume for that track to it's lowest through the audio mixer and audio renders correctly. And thanks to all who identified the scenarios that cause this.
