Audio pieces missing after rendering

[Lars5F99]

Dear Community, in Premiere version 15.4.1 I have a perfectly good audio in the preview and while editing the video, but not when rendering the video out.

Every time I render the Video, the audio of a few video clips is missing at random places. It is never the same audio piece that is missing. Sometimes after rendering the same video, a specific video clip has audio and the next time it doesn’t.

Strangely enough, this only applies to one soundtrack. I can still hear mp3s on the other audio track. If I change the audio of the video to another track, I have the same problem there.

The error cannot be cleared by copying it into a new sequence / project. It also happens at different rendering settings.

Any ideas?

Hey Lars – 

Could you let us know what type of clips you're editing? Are these .mp3s that you downloaded from somewhere? Sometimes files that are pulled from Youtube show weird behavior in Premiere, that's why I ask. 

Let us know

Caroline

Hello Caroline,

it is material from my GoPro Black9. What I have tried so far:

• I made sure that all my hardware drivers are updated
• I verified that the sound is played correctly before exporting
• Removed all audio effects and transitions and used a single audio track
• I created a fresh audio track and duplicated the audio clips into this new track
• I've tried uninstalling and re-installing Premiere
• I've tried installing an older version (15 & 15.1), older Versions than 15 cannot open the project
• I copied the clips and pasted them into a new sequence
• I exported the video (H.265) and put it back into Premiere in order to remove the parts that had no audio and exported it again. The final video had missing audio at random places that were new.  
• Change Audio output von 48HZ auf 44100 HZ
• rendered direct with the Premiere and not using the Media Encoder
• in Premiere: export through "Software Only" / export with Hardware encoding unchecked (trying as we speaks, take 32hours instead of 30 minutes)
• in Media Encoder (ME): export it through “Mercury Playback Engine –Software only” / export with “Mercury Playback Engine GPU-CUDA”

thanks for any idea to fix this issue. It is getting so frustrating!

try transcoding your sources to an all i-frame format like prores.  relinking should be pretty straightforward.  mpeg video is not ideal as a source for editing.   It usually works...  but not always

[Stan254116261oe9]

I have the exact same issue with v22.0. For me it seems that the audio drops at volume keys.
Is it a memory issue? Would be great if this is fixed asap. 
As a work around I have to render the final video about 3 times and then cut the correct audio from one video into the audio gap  of another video. It's very annoying.

[Michael Grenadier]

first, is this an issue that first occured when you updated to 22.0?    Any reason you haven't updated to 22.5?  Not that I'm recommending that as updates can cause issues, but always a good question to ask when trying to troubleshoot from a distance..

Please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card and your source properties and sequence settings (codec and sampling rate).   First step is to make sure that audio is uncompressed (either aiff or wav) and that the sampling rates all match and are a minimum of 44.1k 16 bit.

If any of your source material is from a smartphone or screen recording, the problem may be caused by variable frame rates.  Here's how to confirm the diagnosis and fix it

use mediainfo to determine whether your source is variable or constant frame rate

if it's variable use handbrake to convert to constant frame rate setting the quality slider in the video panel to maximum
https://handbrake.fr
and here's a tutorial on how to use handbrake

Please approach this in a systematic fashion and let us know if any of this helps...

[Stan254116261oe9]

Thank you for this fast answer! OK, I did some research. My WS has a AMD Ryzen 9 16-Core Processor. 32 GB RAM, Windows11, NVIDIA GeForce RTX 3060. For the actual project I'm using 4K files from iPhone (.mov and .mp4 mixed) only. I had no problems with this footage setup until v22.0. For testing I set the output parameters to 'match source' (and I tried also Vimeo and YouTube 4K and 2K setups). In a 20 minutes video output I get around 12 - 15 gaps (audio from one of the 3 tracks is cut off for the time until it hits an other audio key) in the audio output. After having updated to v22.5 I have around 2-3 gaps left. My footage consists of dozens of clips. Do you really think that I have to convert all these files prior to be able to use them in Premiere Pro? Files, that were ok in versions prior to v22.0? I never had an issue with iPhone video files before (in the audio section).

Did you ever solve this issue? I am having the same problem ... with GoPro footage.

[Lars5F99]

Unfortunately, I never solved it. I am using a work around which means I render the audio first, then the video and then bring them together in a new project. The final result works. Not great at all but the best that I can get. 

[Iulian252310804w04]

Hi, guys, I have the same issue here. Some pieces of audio are not being exported. If I render a separate 1-minute video that includes that piece, it works; if I render the project at once, it misses some spots. The same ones each time. The pieces are all filmed at the same quality. I really cannot figure this out.

[Daragho]

Has anyone found an actual fix for this? I'm on the most recent version of Premiere Pro, and I've tried it on the most recent Beta. This is a real time-waster. I'd appreciate any help.

[Michael Grenadier]

Never easy to troubleshoot premiere problems from a distance so please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card and if you have any 3rd party plugins installed for Premiere... Also, sequence settings and clip properties can also help. Although you can throw almost any format into premiere, some formats can be problematic, particularly on an underpowered system.     If you have any questions about how to provide this information, please post back

[Daragho]

Hey,

Thanks for posting Michael. Below are the details.

Processor - 3.8 GHz 8-Core Intel Core i7

Graphics - AMD Radeon Pro 5500 XT 8 GB

Memory 16 GB 2667 MHz DDR4

No third-party plugins for Premiere Pro.

I back-installed Premiere Pro 23.5 the other day (as I had read somewhere that it was a version that was not experiencing this issue. I had 24.0 when the issue started).
I’ve also tried the latest Beta (I can’t think of its name).

Effectively, I’m working on long videos at the moment (the most recent is one hour and 5 minutes). It all looks great in the edit. Audio levels are good, and the whole lot is viewable. But then, when it comes to the rendered video, audio is missing in random parts, and when looking back at those parts, the video freezes (the timer keeps going), and then everything takes off again 20 seconds down the line.
The strange thing is, when I go to render again, the same thing happens, but in different spots!
I hope that helps!

[Michael Grenadier]

The difference between your sequence frame rate and your source frame rate may be the problem.  I'm under the gun on a job right now, but try changing your sequence frame rate to match your source frame rate and see if that solves the problem.  Of course, that may cause other issues depending on your delivery requirements.  

[Daragho]

Thanks Michael. I appreciate it. I'll look into that. I've just tried a different output for audio. Gonna see how that goes (as it's rendering now), and then I'll try your suggestion. 

Thanks again.

[Daragho]

Hey all,

Thanks for your help on this. I finally made it work for me. I changed my audio output to MP3, and that did the trick.

However, to echo the sentiment in much of this thread, I have lost a small bit of trust for this product (I've used Premiere Pro for years and really like it), but now I have to double-check all of my renders, and because some of them are large, it does take up a lot of extra time. 

Michael - thanks for responding to me and everyone else as well. I appreciate it. Fingers crossed, this may get resolved fully in the near future. 

[Michael Grenadier]

Most people are not experiencing these issues so if you want to continue troubleshooting this issue,post back. 

[Stan254116261oe9]

I'm currently using build 62 of Premiere Pro CC and have provided all the necessary information about my setup to Adobe. It's imperative that Adobe addresses this issue promptly; it's astonishing how much time we've spent dealing with it. And, as you can see, you're not alone in facing this challenge.

As for my personal workaround, I've discovered that before rendering a film (ranging from 5 minutes to two hours), creating a new sequence is effective. I select all the clips in the memory with Ctrl + A then Ctrl + C, then switch to the new, empty sequence and paste (Ctrl + V) all the clips there. When I render this newly created sequence without any modifications, the audio issues miraculously disappear.

However, it's important to note that this can't be the permanent solution. Adobe Premiere Pro has generated such a level of mistrust that I feel compelled to meticulously scrutinize each rendering for audio defects. I can confidently say that the issue is not related to my hardware; it seems to be embedded in the description file of the sequence itself. It's high time for Adobe to take action!

[Daragho]

Thanks Stan.

[Iulian252310804w04]

It's been a while since I posted, but I remember changing the export settings fixed it at that point. I hope it helps, though I don't remember exactly how I did it. Sorry.

[Stan254116261oe9]

These are normal files from my iPhone (see screenshot). As you can see the fps varies from 29.97 to 29.99, some have 30 fps, slow motion has 240.48 fps. What fps should the sequence have to render the audio correctly? My sequence has 29.98 fps (from the first clip entered in the timeline).
There is a second issue related to this behavior: if I drag a single clip on my timeline, Premiere refuses to add the video part of the clip, it adds only the audio track to the timeline. As soon I select two or more clips simultaneously, Premiere adds the audio and video tracks without a flaw.
What happened to Premiere during these last updates? I had these issues never before.

[Michael Grenadier]

aha!   smartphone videos are variable frame rate which can cause intermittent and unpredictable problems.
use mediainfo to determine whether your source is variable or constant frame rate
https://mediaarea.net/en/MediaInfo/Download
if it's variable use handbrake to convert to constant frame rate setting the quality slider in the video panel to maximum or use shutter encoder https://www.shutterencoder.com/en/ which allows you to transcode directly to prores or other mezzanine formats, "First choose a video codec.
Then in the "Advanced features" section check the box "Conform by:" and set your frame rate in images/seconds." from ShutterEncoders FAQ. You want to figure out what the original target frame rate of the smartphone or screen recording was and set to that in the conform dialog.  set the frame rate to whatever you had it set to record at on your iphone.  I think the iphone records at 30fps NOT 29.97.

Kind of overwhelmed with a job at the moment so I may have missed something

[Stan254116261oe9]

Dear Michael,

I find it difficult to believe that this is being seriously considered. The implication here is that all of us, the users, would need to go through the extra and time-consuming step of translating our video footage – potentially hundreds of files – just to make them compatible with this new version of Premiere Pro. Such a step was never necessary in previous iterations prior to V22.

I would expect Adobe to establish input filters or mechanisms to handle these file types seamlessly. Everybody is working with smart phone footage today. Having to translate all video footage outside of Premiere, just to restore trust in the application, cannot be considered a viable solution. I kindly request that you bring this frustrating issue to the attention of your development department. Your efforts are greatly appreciated in advance.
