Question

How to make AME as good and fast as FFMpeg?

Hi,

I want to encode an image sequence (JPG, 1920x1080, 10.184 frames, 25fps) and an audio file (wav, 48kHz) to an H.264 AAC MP4. No edits, no effects, just encode. So I put it in a timeline in Premiere (2020, 14.0.1 Build 71) and send it to AME (14.0.1 Build 70) with the settings VBR, 1-pass, 6-8 Mbps, Maximum Render Quality on, AAC 48khZ 320 kbps, Renderer Mercury Playback Engine - GPU CUDA.

My System: AMD Ryzen 3900X, 64 GB RAM, RTX 2080Ti (Driver 442.19), Win 10 Pro (10.0.18363), image sequence is stored on PCIE4-SSD.

 

I also send the same to FFMpeg with appr. the same bitrate using 1 pass and the quality factor, which is not available in AME.

 

AME needs 14:52.

FFMpeg needs 3:22, that is 4.4 times faster!

Also the FFMpeg version looks better, with AME I get fractals in noisy areas, which is not the case with FFMpeg. Again, the resulting bitrate is about the same (AME 6200 kbps, FFMpeg 6400 kbps). I have also tried giving AME a little higher bitrate (7 Mbps), still fractals there.

 

So freeware beats giant Adobe by far! But why? Am I doing something wrong? I still would like to use AME, because it is just more practical together with Premiere and AE, but under these circumstances it is not usable.

 

Thanks,

Bob

Why are you turning on Maximum Render Quality?

It was an attempt to get rid of the fractals, because, well, it says maximum quality... but I guess it has nothing to do with it and is more about scaling. I have tried it without as well, and now also with the new versions 14.0.3 (both Premiere and AME): It makes no difference, neither to render time nor quality.

Also I tried the very-slow-option of FFMpeg, then it doubles the render time (which is still twice as fast as AME), but it manages to get the same better quality into a bitrate of 5400 kbps.

AfterCodecs uses FFMPEG in AE/PPRO/AME and is supposedly a lot faster so you could try that. Note that any QuickTime formats with FFMPEG aren't genuine, they're reverse engineered, so you may run into problems with some hardware
