Media Encoder 2020 render extremely slow

I, too, was having extremely long encoding times when using Adobe Media Encoder.  I read somewhere to bypass AME, and just Export while in Premiere.  I think it relies on the computer's hardware more.  Did a test export of a 2 min clip.  Worked great.  Now it's currently exporting the entire 40 min video.  It's halfway through the process.  (Estimated 2 hour time for the whole video).

OK, I finally lost patience with the atrocious hassle ME has caused me, the final straw being it starting to hang at any random point in an after effects render. Enough. The solution my friends is don't use it. Simple: get the Rainbox media encoder - DuME

It's free and it works beautifully, simply. Blood pressure now heading back down. Note to Adobe: simple, fast, and effective is better than cumbersome, error-prone, and infuriating. Just fix what you already have and stop adding stuff until you've done that. Please.

I am having the same issues, the most stable version I have found is 14.3 (14.7 is almost unusable). A test I have been running is on an 8 second clip, with version 14.7 the H.264 took over 1hr 44 minutes and at version 14.3 it's at 13 minutes.

I am glad I found this thread. I must admit, I am a new content creator but I am the kind of person that researches and seeks advice and loves to learn how to do things right. I'm on a Ryzen 9 3950x, 2080ti, 32gb RAM system. I specifically bought this rig to allow me to game and edit. I've learned that H264 is a delivery format and can be the reason for playback being laggy in Premiere. My queries lead me to proxies being the solution. After research I managed to set up an encoding and ingests preset (Quicktime format for multi-channel audio) to make 540p proxies for my 1080p footage (3 videos, each 2 hours long). Media encoder is currently running and the first proxy is going to take 5+ hours....... for a 540p proxy. Wtf? If I'm lucky, all thre proxies will take 15 hours total. Something tells me I won't be lucky. 

Not sure if I should let it run or if I should try reverting AME to the version others have specified. 

It was getting demoralizing to think it was my machine at fault, despite investing a good amoubt of money on it. Maybe it isn't my machine? and maybe I did learn the right things but the problem is actually Media Encoder? 

I'd appreciate any other tips to try, please oh please!

Hey Adobe, if it helps you track down the issue, I think Ryzen-based systems might be the common denominator here.  Might be worth looking into.

I'd like to add to this. I also have the same issue with Media Encoder. Maybe my info will help understand what's wrong.

• So I'm trying to render a video that I've slowed down in Premiere Pro. No effects, no nothing, just slowed down video and that's it.
• When I'm rendering directly from Premiere Pro, the 2 mins video renderes in like under 30 seconds using the hardware render. That demonstrates that it's not my local issue.
• When trying to render with Media Encoder though, it either crahses with no error, or shows me ETAs like 235 hours and after like 15 minutes crashes without error.
• When I switch to software only render, it renders successfully (although in about 3-4 minutes instead of under 30 seconds like in Premiere Pro) but crashes after completing.
• And it seems like it ignores rendering presets that I'm sending from Premiere Pro because it creates .m4v video file with a separate .aac audio file while I'm trying to render h264 into .mp4. And when I'm trying to edit presets directly in Media Encoder, it crashes.
• Tryied to run as admin.

My PC:

• Lateset Windows 10 20H2
• CPU: Ryzen 7 3800X
• GPU: Radeon RX 5700 XT with latest drivers.
• RAM: 32 GB at 3600 speed.
• Everything is installed on SSDs.

I've no idea what's going on and I really hope that these issues will be resolved asap.

Does anyone know if this issue was fixed with 14.7?  14.7 as a whole hasn't been added to the Fixed Issues list yet.  I'm scared to update until we get some word on this.

I have asked Adobe tech support about exporting AE comp using media encoder. 

One of them told me to move my third-party plugins to my desktop, and leave only dummy.txt file, and then reboot AE. 

Another of their tech support told me that I should use custom presets/ medium bitrate when exporting thru AME

And I read online that some ppl found solution by downgrading AME to 14.4, 14.0, and 13 something.

Others downgrade their AE, however for those on OS bigsur, would have to stick to the latest version of AE, as older versions are not compatable. 

None of the above have solved my issues with slow rendering, but in case you haven't tried.

Can we please get some kind of word from Adobe on this, even if it's just acknowledgement?  I'm geniunely scared about the possibility of a future where this doesn't get addressed.

Same issue here!!  I was shock to find that a 53 sec comp  exporting H.264 1080p 23fr would take more than 2 hrs with out third-party plug-ins, no heavy effect, no audio and no colour correction. 

Whats even funnier is that it says " QUICKLY OUTPUT video files for virtually any screen." The irony!!
