The last few times i uploaded something to Vimeo, I get a message after upload saying "This video's audio data rate is 1536 kbit/s, which is higher than what we recommend".

When i get item properties in the timeline, my audio data rate is:

48 KHz
Data Rate 187.5 K/s

Looking at the exported H264,
Audio data rate is 1.5M/sec
Aud rate is 48KHz

Can I lower this? And how?

H264

Thanks

[john mahoney] "Can I lower this? And how?"

H.264 is the video codec. What's the Audio Codec?
You can target the audio data rate just like you can target the video data rate in virtually any encoder. Even the preset based encoders wouldn't use a data rate that high for audio.

Of course if you chose PCM or some other "uncompressed" audio codec with your video codec, that would be a problem. The solution being chose a codec such as AAC for audio and set the data rate.

Thank you,
for some reason linear PCM was selected on the export. I switched it to AAC.
