Changing compression ratio

[JoeBlow]

Folks, I'm new to VS Pro .. was using Premiere Elements 2.0. I have an issue on exporting my video to YouTube via MP4: I can't seem to change the compression ratio, it seems fixed at 128k. This lousy ratio is causing compression artifacts given that the source audio has a low level hiss.

How can I improve the compression?

Hi
You dont give any details of your original video files, knowing these may help in advising you on sizes.

Try Share Create Video File - Custom - Save as type Mpeg4

Or Create your own template ---- Make Movie Templates Manager

Thanks, Trevor, good point about details: MPEG-2 VBR, 448k bps 5.1 dolby digital audio.

Your suggestion provided the options I was looking for, thank you. Lower compression (higher quality) didn't make any difference. And when I reduced the noise in the original audio, it was still high enough to produce the same unpleasant artefacts (warbling). I noted that the audio spectrum had a lot of energy above 14kHz and considering the noise level, I doubt there were useful data up there, so I applied a sharp FFT filter at 13.5kHz, rolling down to -30 db. That helped a bit, but the essential problem is garbage in/garbage out.

Given the poor source quality, this was a quicky project really just for friends and family, and the results are adequate so I'm good to go.

Thanks again.
