Transcoding to E-AC3

Post by dm29 »

Description of problem or question:

HandBrake doesn´t allow transcoding to Dolby Digital Plus (E-AC3). Only passthrough and only when .mkv file is used. I would love to transcode high bitrate sound, such as TrueHD, DTS-HD or Dolby Atmos to E-AC3, as my target device supports it and I could somewhat offset compression with bitrate. Any way to do so? Maybe through CLI or Extra Options?
Thank you !


Steps to reproduce the problem (If Applicable):

Try to transcode to E-AC3. Only ordinary AC3 is available


HandBrake version (e.g., 1.0.0):

No matter the version. 1.1.1.


Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

Windows 10

The nightly build supports 7.1 aac passthru in MP4. Encoding will be added eventually now that we have switched from Libav to FFmpeg.

Thank you both. I heard something about it. So there´s no way to encode to E-AC3 at present? Not even by using .mkv container or CLI command?
Thank you

You can both passthru and encode E-AC3 in the nightlies when the container is mp4. Encoding might be limited to 5.1.

Thank you. I will give it a try. I should expect output quality to be the same, don't I? Just program instability or manifest bugs could appear by using Night Biulds, right?

I tried and saw no difference. Under mp4 no E-AC3. With mkv, passtru only.

I guess the Windows gui needs some additional changes.

So, what are my options? Maybe through HandbrakeCLI? Extra Option?
Thanks

Wait until it's fully implemented. Nightly builds will get it first. See https://github.com/HandBrake/HandBrake/issues/1085
