Does Podner use the Quicktime encoding engine or does it use the x264 etc?
I think QT produces better looking files.

Podner encodes using QuickTime's MPEG-4 and H.264 components.
We agree that QuickTime can produce better-looking files than say, what we see with tools that use ffmpeg and x264. Overall, QuickTime's output tends to be sharper and its color more closely matches the original source.

Thanks for your quick reply Keith!
Since QT uses 7.0.4 and 1-pass encoding these days (with "Convert to iPod") option, I was wondering if Podner will enable me to go back to "old" QT 7.0.3-style of encoding which used 2-pass?
Also, what encoding specs does a 2-pass or multipass encoding contain in terms of bitrate (both video and sound) etc?
Many thanks again.

Podner does indeed provide iPod-compatible H.264 MultiPass, almost identical to the "old" QuickTime 7.0.3. Podner's H.264 MultiPass, Best Quality, matches QuickTime 7.0.3 by specifying a data rate of 600Kbps. Custom settings that include MultiPass will most likely not be iPod-compatible.
Below is a list of Podner's data rates and audio specs.
iPod, MPEG-4, 320x240:
iPod, MPEG-4, 480x480:
iPod, H.264, including MultiPass:
Podcast, H.264, including Multipass:
Podner specifies 16-bit, stereo, 44.1KHz AAC at 128Kbps for all iPod Encoding presets. It specifies the following for the Podcast presets:
Good: 16-bit, mono, 44.1KHz AAC at 64Kbps
Better: 16-bit, mono, 44.1KHz AAC at 96Kbps
Best: 16-bit, stereo, 44.1KHz AAC at 128Kbps
