batch script aerender to output H.264 with CC 2018
on Jul 10, 2018 at 9:24:22 am

Using After Effects and Media encoder CC 2018, I need to render out multiple videos to H.264.
I would like to create a batch file to open many instances of aerender.exe so that rendering uses all the PC’s cores to render the videos in parallel.

Based on info here:
https://helpx.adobe.com/after-effects/using/automated-rendering-network-ren...

I need to use: -Omtemplate “MyPresetName”
In order to choose H.264 to render to.

However, in AE 2018 there is no H.264 export option any more so I cant make an H.264 preset to call with the batch script.

Is there any way around this?
- Perhaps there is a way to open multiple Media encoders rather than aerender.exe (which opens instances of After effects I think)
- Could there be a hidden way to access H.264 in AE in order to make the preset?
- Perhaps the batch script can call a Media Encoder preset instead? (seems unlikely)

Many thanks for any nudge in the right direction!!

I think the hard work has been done for you with these two products:

RenderGarden:

AfterCodecs:

Thank you, Walter.

It’s great that these tools exist and hats off to Mekajiki and Autokroma for creating them.
The free trial for “AfterCodecs” is very generous too, unfortunately I normally need to run off H.264 previews at 1080p so that’s a non starter.

I can’t help but think that, when upgrading to CC 2018, we shouldn’t need more commercial tools to get back lost functionality.
Even though rendering H.264 via AE is inferior compared to ME, it’s still good enough for quick tests that need to be generated fast. Adobe ditching it in AE seems harsh.
Perhaps too many people were trying to use H.264 via AE as a final output, and Adobe wanted to put an end to it?! ☺


As far as a DIY H.264 method goes, guess I’ll just render out DnxHR or similar via instances of aerender.exe and convert these to H.264 in ME.
The proper work flow!

For situations with many “quick to render” comps there may not be a time saving though.
If the H.264 conversion (which must be done 1 video at a time) renders in a similar time to the AE comp then I might as well just send directly to ME instead.

Let's hope Adobe get ME multi-threading, or ME multi-instance operational soon then all of this will be a moot point!!
