Imported audio into the video is at 384 but when exporting the final movie it is decreased to 160 bit rate. I require it to be at 384 or above. How do I correct this?
Hi,
Why?
Can't be done, even in Video Pro X and you are using Movie Edit Now, which is free. (You used MOVIE EDIT NOW as the category.)
The max. in VPX is 192 kBit/s.

What program would allow the proper bit rate?
The programs are not the limiting factor. It's the standards set in the video export codecs set by the companies that create and licence them.

Hi
The high bitrate of 384 kbits/s would suggest you are working with and wanting to export the video with Surround sound - is this correct?
If so then Dolby AC3 Surround Sound is not supported, due to licencing conditions, whether you are using Movie Edit Now, Magix Movie Studio or Video Pro X, while AC 3 SS can be imported it will be mixed down to Stereo at 160 kbits/s - you should be getting a warning message about this.

Perhaps this applies to "paid" programs but freebees certainly will export AC-3 at 384kb/sec and more. Handbrake, for example, will even passthrough 5.1 AC-3, as well as re-encode it.
We need more details about your source audio and what output format you want. I have read that 384kb/sec MP2 audio (eg some DVDs) equates, quality-wise, to only 192kb/sec AAC audio, which is the standard audio for MP4s.
Hi Al.
To my mind there is little to be gained by re-encoding once a video is edited and the export render does not support the original file specs. The damage if any is done and already baked into the resulting file. Changing a file at that point does not improve the quality in any way. 192kb/s for a stereo mixdown should be sufficient as you suggest as the the additional bits are only supporting the additional 2 channel 5.1 or 7.1 audio tracks which are individually 192kbs each.
Because of the ongoing problems with Dolby Labs withdrawing support for AC-3 encoding with Adobe and other vendors due to Dolby Labs not receiving what they claim to be licence fee dues being paid, I'm not sure which video editing packages if any support AC-3 any more.

Thanks for the info. Distrokid video says what Apple , Vevo etc. requirements are for submission of videos
I am a musician and write and record as BwanaAlive. I have been adding the audio music in mp3 format. I am going to add the music in wav format and see the results.

Hi.
If you are using RED book mp3s they are typically 16 bit although some non conforming mp3 files can go as far as 20 bit. AAC files are 24 bit so a much better dynamic range although most of that is normally lost as most people tend to over compress their files when mixing down. 48kHz is just over twice that of very good human hearing so the oversampling has head room for the high pass filter which kicks in at 20kHz and results vary depending on the quality of the end ADC and the signal to noise ratio as well as the total harmonic distortion figures. In my opinion, with acoustic recording, more quality should be placed at the microphone stage and the amplifier and speaker stage where quality loss is most noticeable than worrying about the digital domain. Obviously bad or cheap design DACs and ADCs do not help but the sampling frequencies and bit depths of normal RED book CD quality is better than most people's hearing as everything above 20kHz is filtered out. Try sending a sweep oscillator though any recording application and then export it and look at the waveform that comes out of the analog stage. If it didn't most tweeters would start to burn out at any type of real power output, the voice coils would heat up through rapid vibration.
There is a case for keeping to higher sampling rates during recording and mixing if possible while it remains in the digital domain to give better separation and space within the mix and to eliminate any electrical induced noise at lower volume levels, but for exporting to a final file for general listening I think you would be looking at very expensive audiophile gear to really hear a distinct difference.
For some absurd reason Magix doesn't allow aac audio only files to be imported to Movie Studio and is only available in Video Pro X. AAC audio can be imported as a part of an MP4 file though with Movie Studio. Why?
Ray.
I am going to save the audio in mp4 mode then reintroduce it to the video and see what happens. Thanks for all the input.
Movie Studio will accept wav files up to 32 bit 96kHz if you are really worried. It's just difficult to justify acoustic recordings made when most microphones don't have that type of noise floor. 24 bit seems to work just as effectively.

Hi
. . . . Distrokid video says what Apple , Vevo etc. requirements are for submission of videos . . . .
Where? I can find no mention of this being a specific requirement on Distrokid, the only requirements they mention are within the video standard specifications.
Apple, Vevo and other similar sites do not specify 328kbits/s as a requirement - they class 192 kbits/s as high quality and accept down to 96 kbits/s as standard quality, they do specify that the sample rate must be 44.1 or 48 kHZ and 16 bit. minimum, higher is not necessary but some will accept higher bit settings.

I would worry more about the mastering requirements.
Hi John.
The recommendations are for the Spotify uploads but I'm not familiar with Distrokid or spotify.
Ray.
Hi Ray
@wmcalister is, AFAICS from the comments, uploading music videos through Distrokid who are one of the many sites that offer one stop shop distribution for creators.
In this case video standards apply.
John EB
Hi John.
I followed the links from the Distrokid website as they distribute to several sites.
You asked where he got the specs from.
