Podcast Compression Pipeline . . . A Little Complication

2008
Took me hours to decide on a name: The Artist’s Bane. A friend of mine came up with it, so I don’t take the credit on coming up with the name. But it is a good one.
I managed to get an affordable compression. I’d like to share them in case someone else is wondering what kind of compression works.
Specification as below:
High Quality: HDTV PAL. (1280×720, 25p)
I’m using Xvid MPEG-4 Codec with default settings.
Audio is compressed a lot: 8000kHz, 16-bit, Mono.
File size: ~320kb per 4 seconds of footage. 4.8Mb per minute.
I’m only speaking and it serves its purpose. If and when I have sound effects of music, I may have to up-spec the audio compression.
Low Quality: 640×360 25p
I’m using the standard FLV flash video setting.
Audio is also default.
File size: ~180kb per 4 seconds of footage. 2.7MB per minute.
The FLV is streamed online right on the site, as well as for podcasting RSS feed. The HQ version will be embedded on the site for download and archival purposes. :]
