Wow. You might be interested to know that the creative director behind that video is an avid Pentax K5 user.

Side note: I was, and still am, quite proud of that video. It was hard work, on so many levels, and couldn't have done it without a great crew. (and PS we're doing a sequel).

What to do about static sound in videos?

First post. I'm brand new to the forum and a brand new K5 owner. Received the camera two days ago, with a 55mm 1.4 DA lens. Impressed - so far. Impressed with the video too.

I've observed a few statements like this one above from Dave, and I feel compelled to dispel a myth or two.

I spend a great deal of time in video edit suites - and I can tell you that MJPEG is preferred, as a format, over H.264 for two main reasons. Frame image quality and the ability to scrub more easily through scenes. H.264 is so aggressively compressed resulting in a lot of detail getting lost between keyframes. H.264 is also a huge burden on the processor during decoding - this makes scrubbing (quickly moving forwards and backwards through a scene) unbearably slow, if not almost impossible, during editing.

I use a Canon 5D often for client video production. The 5D uses H.264 compression. It's a pain in the ass to edit with. I for one, am very pleased that Pentax opted for MJPEG over H.264 for it's video format.

There is a downside - with that extra quality in frame image detail comes extra file size. MJPEG files are considerably larger than same duration H.264 files. But I'll take quality and the convenience of easier editing over reduced file size any day.

Overall, I'm very impressed with the K5 video. More so than I expected to be. And, in a great form factor too (more compact than the Canon and Nikon counterparts). Although I do wish we had greater options for framerate control. I'd like to see 24fps through 60fps at both 1080 and 720.

Michael.
