Bug report: After upgrading to Premiere v15, exporting an H264 file from either Premiere or Media Encoder to my NAS creates a file which the program claims exported successfully, but actually creates a glitched file. At some point in the file, the audio will drop out, and the video will freeze on a single frame, which will remain on screen for the rest of the duration.
Exporting a quicktime file to my NAS doesn't cause this problem, and exporting an H264 file to my internal harddrive doesn't cause this problem, so there's only an issue with the combination of encoding to the H264 export setting to a NAS location that is causing a problem.
This is hugely disruptive to my workflow, and I really need it fixed...

I think I have found a solution (in that my mate Jimbo suggested it!!!).. and working for me so far... the 2 pass VBR does work, BUT who wants to encode twice haha! So.. my situation is I have a Synology NAS - it oddly glitches on my export/encode, about 90% in - MP4 / 1 pass vbr selected. It had previously also sometimes created a 51kb file (so no data / video at all). I am connected from my imac as smb://***.***.**.*** I went into my settings on the server - using the synology software / dashboard and in "File Services" I disabled AFP. Just untick it. So now I just have the "SMP service" active. I didn't need to change my login address on my mac, as I already had it setup to connect as smb when you go to "Connect to server" on mac. If you have logged in to your server as afp:// just change this to smp:// (and then insert IP address or whatever your login is). Be good to know if this works across the board, not just synology servers. I'm sure it will. Lemme know! :)

This is definitely an h264 encoder issue that also effects files exported to desktop. Strangely though, we only notice the issue when we stream the final file from our NAS. But I imagine there is something corrupt in the file.
It’s great that AfterCodecs doesn’t have the same issue, but Adobe should fix this.
Antoine Autokroma commented
Austin are you sure it's an issue because you're exporting to your NAS? ? Seems like normal H264 encoding issues.
You could try our plugin AfterCodecs Exporter for Adobe CC https://www.autokroma.com/AfterCodecs
we have a different encoder than Adobe builtin with more options. The one pass option is already really good

My team is also experiencing this issue. h.264 exports have frozen frames / dropped audio at the end of files when using VBR 1-pass and CBR encoding to render to our NAS. VBR 2-pass seems to be unaffected
These are the workarounds I've been using to get a usable h.264 file:
• As mentioned by a few people below, exporting using VBR 2-P seems to do the trick.
• When VBR 2-P is unacceptable, I use PR / ME 15 to export to ProRes, then roll back to ME 14 to transcode to h.264 CBR or VBR 1-P
• As mentioned by a few people below, rendering to my local machine also seems to solve the issue
Premiere / Media Encoder 15.4
NAS: QNAP TVS-1282T (10G connection) over AFP
OS: Mac OS 11.5.1

I've had that same issue since v15 came out, posted it a while back with no traction :(
Exporting to my Synology NAS or EVO media server both get these errors.
Exporting the came video to my desktop is fine... but a very annoying workaround to something that wasn't broken before :(
Steven Hurst commented
My h264 issue is a little different. Any export from Premiere v15 as h264, even exported to my local computer, drops audio and video frames in the video when streamed from my NAS (Drobo5n wired to router and streamed over wifi). Videos exported as h264 from Premiere v14 have no issue. Tried many things on v15 and couldn't solve the problem.
I don't think this issue is exclusive to exporting to a NAS. It seems like the h264 codec in v15 has issues in general, and streaming highlights them.

Same issue here still. Happens on several different iMac systems running Catalina 10.15.7. Encoding to a QNAP NAS (TS-832X with firmware 184.108.40.2060) over AFP protocol. Hardware and software encoding does the same dropout at the end. The only fix I've found is switching to VBR - 2 Pass. Then it exports fine.
Daryl Brown commented
same issue - just spend 3 hours troubleshooting to no resolve, except to render to the desktop.
even rendering to ProsRes and then to H.264 (if to the NAS) ended up withe same result
Matt Rongey commented
Is there any update on this issue?
Brent Pierce commented
I'm having the same issue with my Synology NAS. Any update to this problem?
Chris Williams commented
This is still an issue, a couple of months later. Using Mac running Catalina (10.15.7) and exporting H.264 to my Synology NAS results in an incomplete file.
Not sure if this is still an issue for you, but we are running in to the same problem every time, but have found that doing a 2 Pass render works every time.
Would love for this to get fixed though
Let me know!
Antoine Autokroma commented
What codecs did you use ? What software to play the file ?
You could try to export with AfterCodecs Exporter for Adobe CC https://www.autokroma.com/AfterCodecs
there is a free 500 frames trial, or H264 is free when resolution is < 720p
Matt Rongey commented
I am experiencing the same issue with both Premiere 15 and 15.1. I am running MacOS 11.3.1. I am getting the glitch using both hardware and software encoding, but the video no longer glitches if I don't export the audio. My NAS is a Synology FS3400.
Same problem here on our Synology DS1621xs+
Quicktime Apple Prores codec exports fine but h.264 has a terrible dropout with audio and video at the end of the exported clip.
Premiere pro 15.1.0 (Build48)
MacOS Big Sur 11.2.3
Glenn Saggers commented
Same problem here! It's killing the workflow of my studio.
We have no problems with exporting an MPEG, or Quicktime or H265. But as soon as its a H264 the last couple seconds of video and audio are lost.
Exporting internally such as to my desktop is fine, so this is my current workaround until this bug is fixed.
I've tried both software and hardware encoding on both iMac and Mac mini.
Running V15 premiere.
Mac OS 10.15.7
QNAP TS-453BT3 with firmware 220.127.116.114
LEONARDO SCUCCHI commented
same here: after update to Premiere/MediaEncoder 15 we found issue while playing .mp4 Pr 2021 exported file in QuickTime and iPhone.
The same files played in Mac via Vlc or in Windws works well.
The same projects redered withe the previus version (14) works well
William Saunders commented
Tried uploading the files you asked for with the "attach file" thing on here, but... it keeps stalling out. Trying a MASV link, let me know if that works for you?
Has two files, the glitched export, and the proxy file that's the source.
Good Chat commented
I'm also connecting via AFP. Still can't recreate the issue at my end, so can't comment on whether it's an audio issue.
Duane Siedentop commented
I'm an amateur here, don't even know what NAS is, but I'm having a very similar problem. Have been using Premiere 2020 with no problem and just switched to Premiere 2021 (v15) for the first time and exported my project to an MP4 file with h264 encoding and the audio is very glitchy when playing back on my iMac with QuickTime Player. Haven't noticed any video glitches, but the audio drifts out of sync as it plays and if I scroll forward to a different time position the audio doesn't play at all. This is from a single 1 hour video clip from iPhone but with audio completely replaced with a separate .wav file. I do also have some still images overlaid on the video clip. Same thing whether I export directly from Premiere or queue to Media Encoder. I do not have any other video players installed to try, but I imported the video to my DVD maker software and it appears to be working fine there. Makes me think there could be some sort of compatibility issue with QuickTime Player.
