h264 NAS

[williams58505389]

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...

This is a complete dealbreaker for us too. We've got the same issue, and it's about the only thing standing between us and upgrading to v15. All versions pre v15 worked fine with our NAS, but now it's just not working like it used to. Same situation as above - every other format works fine, and exporting H264 to non-networked locations is fine. But H264 export to a NAS fails, even though every other format works. We're on Macs here, I haven't had a chance to test our windows machines yet.

Premiere, AE and AME are all affected. Given how often that people work with both NAS and H264 files, this is really problematic for broadcast and social media professionals.

Thank you for the report. I'm logging a bug now and we'll investigate. If you could provide me with a few more details that would be really helpful:
* What NAS are you using?
* What OS/version are you using
* Is hardware accelerated encoding enabled for the file that doesn't work? If so, does disabling it fix the issue?

Hi Tom,

1) I'm using a QNAP TVS-872XT.
2) macOS version 11.2.3.
3) For the project, I have the renderer set to Mercury Playback Engine GPU Acceleration (Metal). Tried switching this to Mercury Playback Engine Software Only. Output an H264 file with both project settings with both the Software Encoding and Hardware Encoding option in the export settings window. All four test H264 files came out with the same glitch.

Thanks,
-Bill

Thanks for getting back to us - this is really appreciated, as we're very excited to move onto v15 when we know it's ready to roll! Requested details below:

1. We're running two NAS units - QNAP TS-563 and Synology DS1819+
2. Mac OS 11.2.1
3. The h264 preset we use doesn't let me set it to hardware encoding, so I've only been able to test software encoding. In AME, I use Mercury Playback Engine GPU Acceleration (Metal) generally, but was experiencing the same issue with all three rendering options.

I say was, because I just tested this issue, and I wasn't able to recreate the bug again. I ran into a similar situation where I asked Adobe Support to help me troubleshoot, and they went through and reset a bunch of stuff (so it was kinda like coming to a fresh-ish install of premiere, but without reinstalling it), and it worked for the rest of the day after that. Then the next day it went back to having issues.

I'm happy to help bugtest things further, just let me know if there's anything I can test for you

[Tom Nord]

Thank you for the additional information. So two things:
1. What networking protocol are you using to connect to the NAS (SMB, AFP, NFS)?
2. Do you see the same freezing at the end if you export the file without audio? We're trying to determine which step of the export is having the problem and this should let us know if the muxer is involved.

[williams58505389]

1) AFP.

2) Just tried some test exports without audio, and am not having the same freezing issue.

Thanks!

[Tom Nord]

Thanks, that's very informative. Could you tell me more about the sources? Can you repro with just transcoding a single file? And if so, would you be able to share that source? I have a NAS with an AFP connection that hasn't reproduced the issue so far. If it's not a single source can break the project down in to a smaller version that will still repro the issue and share it? If we can get a repro in-house it will make it much easier to determine the root cause.

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.

[tomm24426693]

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.

[williams58505389]

Hi Tom,

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.

Thanks!

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

[Saggers]

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 4.5.2.1594

[s.j.p.h35128320]

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

[default05ms0vn5elga]

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.

[autokroma]

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

[defaultfyhsti5c60jp]

Hey!
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!

[clwill]

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.

Status please?

[Cineblur]

I'm having the same issue with my Synology NAS. Any update to this problem?

[default05ms0vn5elga]

Is there any update on this issue?

[darylb44296444]

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

[vbgenius]

Same issue here still. Happens on several different iMac systems running Catalina 10.15.7. Encoding to a QNAP NAS (TS-832X with firmware 4.3.6.1070) 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.

[steve.hurst]

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.

[Crayonbox_Creative]

I've had that same issue since v15 came out, posted it a while back with no traction 😞

https://adobe-video.uservoice.com/forums/911233-premiere-pro/suggestions/43147761-export-bug-v15-0-0

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 😞

[abcrum]

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


Specs:
---------
Premiere / Media Encoder 15.4
NAS: QNAP TVS-1282T (10G connection) over AFP
OS: Mac OS 11.5.1
