Adobe Premiere Aac Lc
I need to make a video from several clips. The original audio of the clips is in AAC-LC format with 84kbps-94kbps audio bitrate, Mono. The final video will have the same audio format AAC-LC, Stereo. The question is: What is recommended in this particular situation, to output in slightly higher bitrate(eg. 128kbps) or to keep closest similar bitrate (96kbps, it's actually 93kbps after exporting)?

• I am aware that the output won't have better quality than the original if it's converted to a higher bitrate. But I'm wondering what is the best way to maintain the original quality.

But since this is a PP forum, I don't know why you're using AAC audio. If it was my AAC audio, I would use Audition to convert it to a stereo wav or aiff file, 16 or 24 bits, 48 kHz. The reason: AAC audio is compressed. Wav and aiff are not. Since you seem concerned about audio quality, you should know AAC audio will be re-compressed at export, deteriorating audio quality a little bit. This won't happen with wav or aiff.

Try using Handbrake - in the audio options, there is, I believe, an option for audio pass-through of the 5.1 AC3. Another option is Aimersoft's Video Converter Ultimate, which has audio-only converters built in - you should be able to convert the 5.1 AC3 to 5.1 AAC, separate from the video. Then, in Adobe Premiere, import your video file, remove its audio track, then add the AAC 5.1 file you previously created.

Can definitely help you out here.) Good luck!
