Hi,

what I wanted to express was that an external de-interlacer may achieve better results than the use of the internal one provided by the Pro Recorder. But it would be nice to have the option of interlaced encodings as well.

As long as you don’t need encoding support for interlaced formats (like PAFF and MBAFF), yes. 20 Mbps H264 should compare well to 25 Mbps HDV. Interlaced sources should be de-interlaced externally before encoding.

The Fuitsu codec used in the design can also be found in some high-end consumer AVCHD camcorders.

After some evaluation of the H264 Pro unit, I think this is currently a rather limited product intended mostly for web applications.

What I am missing:
Support for interlaced video, currently only progressive encodings are available.
Max. Bitrate is limited to 20 MBit/s, but 24 MBit/s for 1080i60 and 28 MBit/s for 1080p60 are (consumer) standard.
Optional support for TS streams mit 2-channel Dolby audio.

Strangely, the H264 encoder chip used in this product supports all these features, why are the not made available to the user?

Hi,

(1) what is the highest supported encoding bitrate. Looking at the user manual I assume 20 MBit/s.
(2) Is CABAC supported.
(3) When using 1080p50/60 source material are there artefacts using the highest possible encoder setting. Most cameras (SONY HX9, FS100) use 28 MBit/s or more.
(4) How is audio encoded.

Thanks!
