embedded audio Problem with audio in HAP files

[Veehxia]

Greetings everyone,

I've recently been tasked with finding out ways to improve our workflow.

We have a setup of multiple ledwalls and our output resolution is 6592x1678, we usually work with .mp4 H.264 exported at 4096 horizontal pixels and then scaled at 161%.

This takes a huge toll on video quality but it's fine for our workflow and needs.

We tried in the past to use native resolution H.264 .mp4 files but those looks like are not supported by Watchout.

Lately I've been experimenting with HAP files but I cant seem to find the proper way to export them.

My problem is that I cant get any audio to reproduce out of those HAP files, I've tried multiple ways of exporting them from Premiere / After Effects but none of those works.

I've tried the Disguise codecs from GitHub, Jyoko, Autokroma's AfterCodecs and every kind of settings but all of my clips are always mute.

The only way I was able to get proper audio out of those files was by first exporting them at native resolution in .mp4 and converting them to HAP using AVF Batch Converter.

As you can probably imagine it's not really ideal to have to render each file twice, so I was looking for a way to solve this audio issue directly in our first export.

After a bit more of digging this issue, it turned out that every export directly from Premiere in HAP using all the different ways has "PCM" type audio, while those converted with AVF have "AAC" type audio.

How could I solve this?

What are the best ways to export HAP directly from Premiere with AAC audio so that I dont have to convert each clip every time or have a separate export for the audio only?

Thanks in advance to whoever will be able to help me.

Dataton recommends no audio in movie files. Instead, export the audio separately and play it in synch with the movie. https://knowledge.dataton.com/knowledge/embedded-audio-in-watchout
BTW Separating embedded audio is automated in v7

Thanks for the answer and sorry for my very delayed reply.

I know it would be better to have separated tracks but those are all small clips and they are played once, not looped and not run unattended.

I'm still looking for a way to export directly from premiere in HAP with AAC audio as AVF Batch Converted is not available on Windows and I'd prefer to avoid a double pass of our files.

Not for free but very good. Stand-alone software or plug-in for Adobe.

AAC audio is not recommended. Please use WAV. And it doesn’t matter if they are short movies, played once and non-looped… you should separate the tracks. 
 

As Rainer said, Jokyo is good, but you can also try ShutterEncoder. Free and multi-platform.

ShutterEncoder is just a GUI for ffmpeg, and ffmpeg's HAP output quality is terrible.

Pay the money for Jokyo, it's worth it.

I always use audio in different file .wav

And I use ffmpeg script to extract the audio and mute de video file.

Actually I have scripts for all my needs.

As you can see on the picture all scripts extract audio from the files, so I end up with 2 files a muted video and an .wav file.
