Conversion & Size Reduction of a ppt

[swfwebmaster]

The initial Powerpoint presention of approximately 80 slides was 18 MB. I then converted the slides to *.png format which increased the size of the document to 56 MB. When I added the narration, the size of the file exploded to 209 MB.

The reason for the large increase was the audio format. Instead of using the default setting of 11.025 kHz, 8 Bit, Mono @ 10 kb/sec, I opted for the highest setting of 48.000 kHz, 16 Bit, Stereo @ 187 kb/sec. I thought I could always reduce the quality of the audio after the fact, but have been unable to find a solution.

When it has been merged you will not have the opportunity to reduce soundquality, unless also comprimising picture quality. There are more shades to grey, so maybe somewhere in between with lower hertz and maybe less bytes per. second would optimize. Making the initial powerpoint into png-format could also prove less helpful. Maybe putting them in pdf format would help, although I don't know how well and how easily narration is added to that format. You would need special software for it, I think.

Thanks. It just needs to the narrative re-record.
