My mistake

Thanks for the idea Adam. Looking forward to seeing the grades.

Adam there are so many posts here referring to the Pocket Camera as BMPC. Would you consider renaming the thread "BMPC4K Grades" so we can distinguish the threads at a glance of the thread title? Thanks.

Thanks, Adam. Doing the download but I imagine there are many people trying to do that too as I'm only getting about 5 MB/s of a 10 GB zip.

Having trouble downloading Grant's files.
Says corrupted or invalid.

MS

They have downloaded here, they look great!

I'm cursed I know it!

Trying again.

I'm sure the traffic from users downloading it will bog down the server so please be patient while the masses go crazy with the file.

Well the Resolution Seems to be there.. but like it was to be expected Even BM can't work miraculous Magic on the CMOSIS Sensor.. especially the Clipping in Highlights doesn't seem to be handled Nearly as Nice as with the "Classic" BMCC, still digging the "Old" Sensor with the higher Dynamic Range much more... so totally right call from BM to openly advertise it as another Alternative and not a replacement.. eventhough Many ppl here hate BMs Communication strategy I highly Applaud their openness about the "flaws"/cons! Thumbs up

Which clips do you feel did not handle clipping well?

Don't get me wrong.. nothing looked really "bad" in those clip, just compared to the high dynamic range of the BMCC it looked "worse" (I don't really like using this word in this regard) ... the Beach Jetty for example, if you look at the right side of the lamp post that's hit by the sun/light...

The night scene with the streetcar approaching is interesting when you see the headlamps. I thought that was handled well.

Been downloading the file for an hour now...

Can anyone at least post some frame grabs or something?

Here's my take. Very basic 15-minute grade: OSIRUS LUT + some IR pollution correction on some footage. I didn't touch the highlights or do any extensive correction. You can download the 4K H.264 file (600MB) for best quality.

There are many sample grades of a frame on the bmcuser forum. They'll start showing up here soon.

Thanks, Rick. I'll head over there now.

Downloaded it twice now and cant unzip the files.

Had zero problems with the download

So now it's this way around? I've been begging other forum users not to use the acronym "BMPC" for the Pocket cam, as it was initially broadly used for the Production cam, while most users back then referred to the Pocket Cinema cam by "BMPCC"; then the news about the Production cam stopped, threads about it went silent, and the original distinction was lost. Now, a mere six months later, we are to accept the adopted acronym for the Pocket and go with a new one for the 4K cam? Funny...

Just a little test, pulled down blacks, increased saturation. Uploaded to youtube for 4k support (This is an x264 upload)

Ahhh, at last, 35mm image!

16mm gives me a claustrophobic feeling.
I really don´t like my Mft lenses at all.

Ben Wells wrote:Had zero problems with the download

I wonder if its to with windows 8

The footage looked strange to me and I couldn't put my finger on it. But I just figured it out. The flipping camera has better vision than I do. The crispness of the image of even the furthest away objects is greater than what my eyeball can produce when standing there looking into the distance. Very exciting! And I guess I need to get my eyes fixed..

HPG wrote:Been downloading the file for an hour now… Can anyone at least post some frame grabs or something?

Here are two versions of a frame from Grant Petty's BMPC-4K ProRes HQ footage. The first version is the original 4K ProRes HQ frame scaled to 1080. The 2nd example is the center 1920 x 1080 cropped from the original 4K ProRes HQ. Note: These are JPEG compressed from 4K ProRes HQ.





EDIT: And here's my video example showing Grant's footage scaled & cropped in a 1080p timeline:


I'm encouraged by what I've seen so far!

Each camera has its strengths, but this footage brings a smile to my face. Can't wait to see what John and Frank and Marco and Rick and Philip and others will hopefully have for us in the next few weeks. Like the ProRes Film. Bring on the raw.

Is the 1080p mode on this camera a crop, or scaled?

AaronChicago wrote:Is the 1080p mode on this camera a crop, or scaled?

According to BMD it will be scaled.

It's early days yet (kinda), but I'm encouraged by what I've seen so far. Note: These are JPEG compressed from 4K ProRes HQ. I may have screwed something up with the files, so go easy...

Peter, what did you use to downscale? Have you tried to downscale the 4K ProRes 4:2:2 image to a ProRes 4:4:4:4 HD timeline to see if there is any colour or detail improvement? Seeing a side-by-side comparison might be useful but the differences may be lost going to a JPEG from h.264 output.

I don´t know what happened, but the files I get are in 1364x766 px only! Any idea?

Very encouraged by what i'm seeing but has anyone else tried opening in After Effects 5.5? i'm getting a frame size of 1364x767, obviously not 4K. Anyone care to shed any light on this. Still loving it though.

Answers on a postcard….

even in the information window of mavericks this size is shown ...

QuickTime is not displaying the info correctly.

Open then in Resolve or your NLE (FCPX). They are 4K2160p.

here's a quick edit:


yah, the files I downloaded are not coming up as 4k as well. Also some were corrupt apparently.

Quicktime? Not doing something correctly? Good heavens, whatever next? Talking pictures?

You may have a point. Same thing happened with a Canon 1DC shoot and it's been telling me that my C300 footage is 16bit. Which it clearly isn't. Anyone out there with a fix? My Resolves are busy on something else. Forever in your debt, first born child etc.

Awesome.

I'd love to read some pro colorist opinions of the footage. Added a thread to Post Production in the hope someone might find the time. viewtopic.php?f=3&t=16634

And actually they are 4k when opened in Quicktime 7 but not in the latest version. Weird.

Files are defiantly 4K (3840x2160).

QuickTime 10.2 on my grading machine (Mac OS X 10.8.5) displays the correct size and the scaled size.

There seems to be an issue with how QuickTime under 10.9 is displaying the info.

Thanks Adam.

These files are are not the same Film mode we have come to love in the other 2 cameras.

If you simply apply your preferred LUT you will end up with an image that is very over saturated. Most creative look LUTs are expecting LOG or REC709 as their input and these files are somewhere in between.

Grading them in Resolve there is a lot of info. Pulling keys with the qualifier tools is a pleasure as the details is really good.

I'm really happy with what's coming out of the camera.

Having shot tests in 4K RAW on the F5 and F55 last week and run through the post workflow I'm really looking forward to see the RAW files from this camera. If the ProRes is anything to go by we are in a very good place.

looks good, the 35mm fov really helps and 4k downscaled to HD looks very sharp. Now, can we have this in a pocket form factor?

They have removed the night shots from the zip file, it's now only 8.15GB
I wonder why?

Darryl Gregory wrote:They have removed the night shots from the zip file, it's now only 8.15GB

Strange. I do not think the night shots are all that bad. They could have done with more detail in the shadows but they don't look like they have been pushed that far. Was also not clear what lens it was shot on, did not look like a fast prime. A nice fast 35mm or 24mm prime would have helped.

I agree Adam I saw the night shots online, and even with compression it didn't look all that bad.
Guess they want to wait for one of the beta testers to work their magic on the low light shots

My neutral test grade with download:

A quick pass in Resolve with a healthy dose of saturation - i can see people LOVING this camera.

Nice work CaptainHook.

The pier image now reminds me of Life of Pie.

Thanks! I'd actually love to know what lenses Grant used on these, the images feel quite 'painterly'.
