export settings in adobe elements

[alx00]

hi i have a doubt in the export settings area about audio configurations.  lets say, if im gonna export in h264, i know the aac format is used at 48khz and is possible to use other aac variations and also that i can choose 512 bitrate but i can find if the audio is 16bit or 24 bit, i need 24, the same thing with mpeg4. another thing, i found that i can export quicktime (i think is mov.) and here in the audio settings it shows me that can be at 48khz and in 24bit but dont say nothing about the audio format(i need wav./pcm).  idont know if  the video is exported with the setting that says uncompressed rgb 8bit or yuv 8bit 10bit the audio will be in the imported format (wav.). ??

thankyou and sorry for my english and to let you know im not a video editing expert.  thanks

Unless you have a specific reason, the AAC 48khz setting needs no change.    The sound quality will be good and they will not be noticble to the ear if you make changes.   

Maybe I could help more if I understood why you change the settings.

Hi bill thankyou for the quick response.  I know the quality isnt going to be extremely inferior or something but im from the audio world so i want the audio to be the best possible. If i upload the video to youtube the site is going to compress even more so thats my issue.  But lets says i use the aac format at 48khz and 512bitrate; you know if the audio is in 24bit because in this particular format doesnt show me? Thanks
