Canon New Movie Codec for DSLR is Coming (Rumour)

http://www.eoshd.com/content/577-Canon-5D-Mark-3-to-feature-new-MPEG-variant-4-2-2-at-50Mbit

With its high bit-rate 4:2:2 colour space MPEG compression, I bet the video quality will be miles ahead of any of the current MPEG4/H.264 compression codec used by most of the current DSLRs and ILDCs in the market. In view of the advancement of video codec in other larger sensor digital cameras of other brands, Pentax is just lagging thousands of years behind, leaving at the Stone Age! :-(

Bottom line: Will the next Pentax DSLR be equipped with a stereo microphone, at least?

Whats the big deal about stero sound on these bodys?? I really see no point in having 2 mics it will acomplish no improvemnt to the onbord sound quility. You will just have 2 channels of crap audio instead of one.. buy an external audio device or an external mic.

The new codec should be cool.

Really disapointed in pentax on the video front I would be happy with manual exposure control and additional frame rates. Its not like these options would be hard to add on the K7 and K5. They would then keep me as a customer. Sigh...

I shoot professional video and all of my microphones are mono.
When doing proper video, stereo effects are all done in the sound mix.

All photography is not photojournalism, where video feature is quite neat adittion.

Yes, BMP is going to be better than JPEG, if you can handle the file size for the same resolution! 16-bit TIFF is even better.

As for video recording, bandwidth is yet another more important consideration. The bottle neck is always at the SD card.

Size of SD cards are not so limiting anymore. They are getting cheaper and cheaper. I don't know if image quality is better in MJPEG or this new format but should be quite good. What is the biggest problem with video on Pentax is that there is NO manual control over it. That's the problem!

Size and bandwidth are two different things.

Bandwidth is OK as well for MJPEG. I never had a problem and I have only a generic (not highest speed) SD card. So what is the problem then? Is MJPEG better quality than MPEG2 or not? My understanding is that MJPEG compress only individual frames so it should be much better for highly dynamic video. But could be much larger than MPEG2, with better and better and larger and larger SD cards ... I don't think that MJPEG is all that bad. It is also better (easier) for later editing.

Bandwidth is NOT Ok in 720p with a Sandisk standard Class 4 SDHC 8GB card, with which video recording will be prematurely terminated at around 1 minute of recording.

As the other questions you are asking, just think about BMP Vs JPEG. Which DSLR is still using BMP as the in-camera output by now? Bottom line: video needs *video* compression, but NOT *still* picture compression to make the file size small, which is just impossible and image quality will suffer.
