multiple aerender instances show multiple "Repeated Frame" messages when run in parallel

Report · Nov 06, 2018

I'm running several instances of aerender, and the logs keep showing this "Repeated Frame" message:

PROGRESS: 0:00:12:00 (1): 2 Seconds

PROGRESS: 0:00:12:01 (2): 0 Seconds

PROGRESS: 0:00:12:02 (3): 1 Seconds

Repeated frame 2

PROGRESS: 0:00:12:02 (3): 0 Seconds

PROGRESS: 0:00:12:03 (4): 0 Seconds

Repeated frame 3

PROGRESS: 0:00:12:03 (4): 1 Seconds

PROGRESS: 0:00:12:04 (5): 0 Seconds

Repeated frame 4

PROGRESS: 0:00:12:04 (5): 1 Seconds

PROGRESS: 0:00:12:05 (6): 0 Seconds

Repeated frame 5

PROGRESS: 0:00:12:05 (6): 1 Seconds

PROGRESS: 0:00:12:06 (7): 0 Seconds

Repeated frame 6

PROGRESS: 0:00:12:06 (7): 0 Seconds

PROGRESS: 0:00:12:07 (8): 0 Seconds

Repeated frame 7

PROGRESS: 0:00:12:07 (8): 1 Seconds

PROGRESS: 0:00:12:08 (9): 0 Seconds

Repeated frame 8

PROGRESS: 0:00:12:08 (9): 1 Seconds

PROGRESS: 0:00:12:09 (10): 0 Seconds

Repeated frame 9

PROGRESS: 0:00:12:09 (10): 0 Seconds

PROGRESS: 0:00:12:10 (11): 0 Seconds

Repeated frame 10

... and so on.

It seems to be rendering the same frame twice.

It doesn't happen when I run the same job in only one instance.

The final render seems to be OK, but does anyone know what this means and how to prevent it?

Did you separate your comp into smaller pieces before rendering and if not, have you checked the skip frames option in the render queue?

Yes, each instance is rendering a separate range of frames.

And there is no render queue involved, each process renders a comp by name, with no "-i" setting.

I've never seen such a output before...

What's the command line you are using, what does the whole environment look like?

Do you get more repeated frames when you start 3 processes on parallel?

On a sidenote: have a look at RenderGarden | by Mekajiki

They are using an AE script for separating the comp and python scripts, to launch aerender.exe.

Actually I'm using a modified version of RenderGarden.

I just realized the "Repeated frame" message is being generated by RenderGarden itself as it parses each line aerender output.

I'll ask Mekajiki.

Thanks

I tried running the same aerender command manually, and it does show many frames being rendered twice:

Why would it do this?

command:

$ "/Applications/Adobe After Effects CC 2018/aerender" -project "/Volumes/Common/_Automation/testing/YV-v6.6-template.aep" -OMtemplate YesDVC -comp "YV2" -output "/Volumes/Common/_Automation/testing/test4/output.mov" -s 0 -e 9 -v ERRORS_AND_PROGRESS

Where is this command-line from? How do you set up your render garden?

I'm wondering about rendering into a MOV with multiply instances, which isn't working. You can only use parallel-rendering in combination with image sequences.

Also, it's using the output module template YesDVC, whatever this is.

Command line is written by hand.

This is NOT rendering multiple instances. Just one.

No parallel rendering.

Output module makes no difference, whether Lossless or this DVCPRO.

The only thing I can think of are fields.

When you put your comp into AE render queue, check render settings as well as output module. If both are as you wish, use your command line without -OMtemplate argument. This is just for trouble shooting...

Just experienced this as well, using Render Garden.

Seems that rendering the proes-file with audio output causes this for me. Turning off audio-output in the render queue fixes it.

Not sure how I'd output something with sound now – I'd have to add it later.

https://forums.adobe.com/people/Aktuba%20Ink thank you for finding out!

I just recognized, that the repeated frames in the output is always 0 secs rendering time. So, maybe this is just an output message and it doesn't affect overall rendering? Could you may make a little speed-test?

Report · Dec 18, 2018

Don't have time to test right now (on a deadline) but I'm sure it was stuck much longer that 0 seconds on those frames – my render also didn't finish properly. Rendering sound separately now and adding it using an old QT7 pro.
