Question

Low sound quality in imported movie

Asked by: muso

I'm working on a project to be distributed on CD, so bandwidth is not a problem.

The project has some video clips, which originate as quite large QuickTime MOV files.

I can't link to these files, because I can't work with QuickTime Flash movies or Flash 5 ActionScript!

However, when I embed the video files I get 2 problems:

1. When embed options are quality=100 (and synchronise to flash 1:1), and Sound=Integrated the video looks fine, but the sound quality is poor (like talking into an empty yoghurt pot!).

2. When I embed, again with Quality=100, but with separated audio, the sound is also of poor quality...

However, with the last point I can then click the properties on the generated Audio symbol, and change them to Compression=MP3, and Bit Rate=64 (or higher), and the sound is perfectly fine.

Therefore option 2 would be perfect, apart from another new problem with the sound being separated: that the sound goes badly out-of-synch with the video (after about 10 secs of video, the sound is out by as much as 1 second).

I have also recently heard that flash can only effectively import audio tracks at bit-rates set at multples of 11, but having had the video's audio track re-encoded from 48KHz to 44KHz (16-bit), the problem remains exactly the same!

Is there anyone out there who has had similar problems, or has any idea what I could do here?

Many thanks in advance!

audio is automatically adjusted to a lower amount to save for a connection of 250 Kbps(25 KB per second) the only way to keep it from doing that is the properties feature. hope that helps some.

where is the property to change it?

I go to the properties for the embedded video, and all I can see are options to re-import the clip

Thanks virtex - you're a saviour!

I found the properties (publish settings); now there's just the Quality/Size/Performance balancing act left.

And again, thankyou!  I am now a happy man :-)
