is there any tool which can copy the video stream and copy the aac AND convert the AAC in the same step to AC3 ?
So the final file would have 2 audio lines AAC and AC3.
Also with an queue function because I need to transcode 100+ Files.
Thx & Greetings

Can be done with Hybrid this way:
- start Hybrid
- set "Main->Primary Input Selection->Video handling" to "passthrough"
- set "Main->Primary Input Selection->Audio handling" to "auto add (all)"
- enable "Audio->Main->Reencode"
- set "Audio->Main->Audio Encoding Options->Audio format" to "ac3"
- set "Audio->Main->Audio Encoding Options->Bitrate (kbit/s)" to "384" (or whatever you want/need)
- enable "Audio->Misc->Handling->Add passthough for reencode"
- set "Config->Path->Default output path" to the target path (alternatively enable "Adjust: Output path to source path"
- set "Config->Output->Container Settings->General Settings->Standard output container" to "mkv"
- enable "Main->Generate"
- drag&Drop all the files into Hybrid (on top of the Input line)
- wait until Hybrid is finished with the analysis of the sources
- press "Main->Add to queue"
- press "Jobs->Start"
- wait till all the files are processed
a. Hybrid is not ment as a One-Click-Tool, so it is definitely not ment for everyone, but it sure can do a lot.
b. Depending on you hdd and general system speed I would also recommend to set "Jobs->Parallel jobs" to a higher value.
Ps.: If you try it and run into a problem with Hybrid, please report in the Hybrid thread. (also read: http://www.selur.de/support ) For new Hybrid users I would also recommend to:
a. enable "Config->View->Design->Show tooltip sidebar", since it allows the user to read the tool-tips more
b. read the [Info]-Threads over at http://forum.selur.de/forum2-general-hybrid-infos.html.
Hi Selur, thx for your response. Your Tool works great. One Question: Is there any Setting to normalize the Audio dB ? Thx & Greetings
Switch to Audio->Main->Filtering (this allows you to set audio filtering options; 'Encoding' switches back to the encoding options)
Normalization is done depending on the "Audio->Main->Audio Filtering->Gain->Method" setting.
You should read [Info] Understanding the audio gain methods,.... to get a basic understanding of the settings.
If you want it more detailed check out the sox manual:
gain [−e|−B|−b|−r] [−n] [−l|−h] [gain-dB]
Apply amplification or attenuation to the audio signal, or, in some cases, to some of its channels. Note that use of any of −e, −B, −b, −r, or −n requires temporary file space to store the audio to be processed, so may be unsuitable for use with ‘streamed’ audio.
Without other options, gain-dB is used to adjust the signal power level by the given number of dB: positive amplifies (beware of Clipping), negative attenuates. With other options, the gain-dB amplification or attenuation is (logically) applied after the processing due to those options.
Given the −e option, the levels of the audio channels of a multi-channel file are ‘equalised’, i.e. gain is applied to all channels other than that with the highest peak level, such that all channels attain the same peak level (but, without also giving −n, the audio is not ‘normalised’).
The −B (balance) option is similar to −e, but with −B, the RMS level is used instead of the peak level. −B might be used to correct stereo imbalance caused by an imperfect record turntable cartridge. Note that unlike −e, −B might cause some clipping.
−b is similar to −B but has clipping protection, i.e. if necessary to prevent clipping whilst balancing, attenuation is applied to all channels. Note, however, that in conjunction with −n, −B and −b are synonymous.
The −r option is used in conjunction with a prior invocation of gain with the −h option - see below for details.
The −n option normalises the audio to 0dB FSD; it is often used in conjunction with a negative gain-dB to the effect that the audio is normalised to a given level below 0dB.
sox also offers a bunch of other filters I can add if need be.
Ps.: to see the command lines uses for a specific job, you can disable "Jobs->Minimize job command lines".
