Originally posted by gybp hi, im interested in this aspect of the camera, video..
i want to know how does it compares to the 7D/5D/D7000, or how is it doing by itself in:
1) Quality (compression, artifacts etc)
2) Rolling Shutter problem... you know the jello effect.. (samples here)
It's there, as it is in all DSLRs. It seems to be on par with my T2i.
Quote: 3) FPS, i know it is limited at 25fps, but i want/need 24/30/60 can this be upgraded via firmware?
At 720p, you can do 25/30 fps. At 1080p, you can only do 25 fps. We can always hope for the addition of 24 fps later on, but I highly doubt they'll add 60 fps.
Quote: 4) Full manual controls: Does it have them? i dont care about autofocus at all
No manual control at the moment. It's one of my gripes with video on Pentax DSLRs, and is the reason I have a T2i as well.
Quote: 5) Audio
Audio seems fine to me. The K-5's sample rate is 32kHz in mono, which is lower compared to the 7D, but is 48 kHz when a stereo mic is used (same as 7D). The K-5, like the 7D and 5D, has a stereo input jack. If you're serious about video, you'll use an external mic on any of these bodies.
Quote: 6) Dinamic range: is it the same as when shooting pictures?
I'm no expert at measuring things like this, but I would assume the DR in video is as wide as the JPEG engine allows for. I'll try a test by extracting a frame out of a scene and take a snapshot of the same scene with the camera in JPEG.
Quote: 7) Use for special FX: chroma key, etc
Beyond my experience level again. There was a short film done by a group using a K-7 that did use green screen though, so I wouldn't think that the camera couldn't be used for effects like chroma key.
If you want to get an idea of what can be done by a regular person on a K-7 or T2i, check out the Vimeo link in my signature.
