Cannot export with any clips that are sped up more than 500%?

[Mystic_child5CE6]

Hello,

This is my first post here, please bear with me. I am using Adobe Premiere Pro 13.0.3 and Adobe Media Encoder 13.0.2. Windows-based PC with plenty of horsepower (Dell Precision 5820 with an Nvidia P4000). The system is not running out of resources, in fact it's not even close.

The problem I am having is that when I try to speed up any clip greater than 500%, it will not export. Media Encoder will either crash, freeze permanently, or the export will simply fail with a BS error code that looks like this:

------------------------------------------

A low-level exception occurred in: H.264 (Exporter:9)

Export Error

Error compiling movie.

Export Error

A low-level exception occurred.

Writing with exporter: H.264

Writing to file: C:\Users\avolpe000\Desktop\MVI_1624.MP4_Sub_03_Sub_01.mp4

Around timecode: 00:00:00:00

Component: H.264 of type Exporter

Selector: 9

Error code: 3

---------------------------------------------

Furthermore, this problem happens with any codec, and any clip. It's only the AUDIO of the clip that causes a problem. If I delete the audio track, I can speed up a clip 10,000% no problem. Alternatively, if I just de-select the audio when I export, it also works fine. I've tried dozens of clips, from different sources and cameras and such. Doesn't make a difference, once I go past 500% speed-up, it will never export. I've tried 600% and it fails every single time.

Now, my videos tend to have tons of timelapses, between 10-30 per video, so needless to say this is beyond frustrating. I've taken to just deleting the audio tracks and replacing them with music, but that's not really what I necessarily want in all cases.

Any ideas on things to try? I am moving from Davinci Resolve which could handle sped-up audio no problems, so needless to say I'm a little confused.

Thanks in advance!

Thank you for reporting the issue.  I could reproduce this issue as well.  But, I needed to set the speed higher than 5000% to reproduce this bug, instead of 500%.   Could you tell me your source audio format (such as frequency, sample rate, duration, and bitrate) that you used to reproduce this bug with 500% speed change?  I reported this to our bug database, but I would like to have better understanding of this  bug.

Meanwhile, I found a workaround of this issue.  Please add Volume effects from Effects panel to all clips you would like to change their speeds.  You can keep Volume effect to 0dB so there is no actual change in audio.  I could encode with this workaround.  Hope this workaround works for you as well.

Hi there,

I appreciate you looking into this for me. Interesting that we had similar results but with different speeds.

Specs from a test clip (as seen in the Premiere properties for the clip):

File Path: I:\MVI_2205.MP4

Type: MPEG Movie

File Size: 3.96 GB

Image Size: 1920 x 1080

Frame Rate: 59.94

Source Audio Format: 48000 Hz - compressed - Stereo

Project Audio Format: 48000 Hz - 32 bit floating point - Stereo

Total Duration: 00:16:04:30

Pixel Aspect Ratio: 1.0

Alpha: None

Video Codec Type: MP4/MOV H.264 4:2:0

If you need more info than that, let me know exactly what you need and where  I can find it.

I will tryout the workout, I've got some more timelapse stuff coming up. Thank you so much.
