  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Gibby's RED takes a dive...Underwater RED 4K

Hmmm... that's wierd. I'm curious how the clip was exported because it looks quite pixelated to me. Not at all like the other clips I've seen. I'm almost sure it's the conversion process because I've seen the same thing in my own work before (usually from Quicktime conversion out of FCP).

Or am I just seeing things? :huh:

The water practically pours out of the monitor... this is very, very nice stuff.

Ya, when I watch the clip I hear Sir David Attenborough's voice over, "...and hidden beneath jungle like kelp a rare and beautiful event that happens only once a year unfolds before our cameras."

No pixies on my download playback. You using the latest QT 7 updates?
 
I noticed the same thing. The clip looks nice, but there appears to be a lot of aliasing on the image if you pause it. I'm running QT7 too.

Have a few shots of BTS of the dunking. Just need to find time to piece together the clips. Will hopefully have tomorrow and offer up the file to someone that can possibly host.

PM me and I can get you st up. It might be nice to keep them together.

I'm guessing we're looking at the x.264 compression artifacts, I see it too. But still not bad for a web compressed 1080p example compressed to that level. Higher quality sampling and multiple passes for the compression could clean up the images at the expense of much longer render times. And I'm making a blind assumption of how clean the original 4K footage is. It looks like it's exceptionally clean and the only real problem is the clipping that Sharky already mentioned. But if you're commenting on aliasing and edge contrast artifacts, then I'd say you're nit-picking. The macro-blocking moire noise in the open water (blue) parts of the image are far more noticeable -- this is also an x264 thing.

Damn, you guys are doing cool stuff! You do know we have a 4K projector at RED, right? :)

Is that an invite for me and Gibby to view our 4K underwater footage projected in 4K at RED HQ? That would something!

Pixies are a QT thing no doubt and probably an error based on the export settings I selected. Smarter guys than me are going to nail this post work flow to enable clip sharing via the web in the near future. Like I posted earlier, the 2K prores on the HD monitor in RGB space is SWEET!

Next up...watch out The Gibster and I are loose in Yellowstone all next week with #8 and a whole bunch of new toys, err, professional equipment for yet another round of incredible firsts for RED ONE cameras.

LART is gonna' rock in October based on what we are doing, testing and learning now.

Claus - Is that timelapse sequence on your mirror from a RED? It seems unlikely that someone could shoot that much great timelapse in so many varied locales in the short time that the RED has been out.

Oh... you're right. I didn't noticed that but it's really nice.

Thanks Richard!
 
Ken, Steve,

just got into Jackson and sitting here in Jackson Lake Lodge Grand Hall overlooking the Teton Range (beutiful day in the mid 40's) and have a few things in place for the week - locations, wildlife, etc - see you when you get here.

The only reason I mentioned it, is because I havent noticed it on any other quicktime examples. It almost looks like some de-interlace process has been used. The macro-blocking is inherant to the H.264 compression format, so I wouldn't worry about that, but aliasing isn't, so it 'could' have occured at another point in the workflow. That was my point.

I'm sure the raw files are fine. Thanks for posting sharkguy, wish I could see it in 4K.
 
Files were compressed from the 4k dpx out of after effects to ProRes codec, then these web versions were compressed with h.264 in Compressor from the proRes files. We didn't notice any aliasing here, i wonder if scaling is an issue depending on the monitor it's being viewed on. Downloading now to view on 19" viewsonic to compare.
 
Nice but what cleaning your lens next time.
Also the operator is abit wobbly for such a larger housing.

If only I had the bucks....
