  • 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 :)

CineForm Officially Supports Red One

Not too complex, I let one for the users explain, as I'm about to go out for the day.

OS X running QuickTime (particular QT Player) is SLOW, we clock our codec core playing at 3-4X speed Quicktime chooses to play it -- not a GPU vs CPU issue. We are working with Apple to overcome these silly limitations, but a think the planned Apple overhaul of QT is much needed. FCP is little better, but play is significantly faster on PCs than on the Mac (same code same compiler.) Companies like Iridas, that use our SDK, bypass QuickTime for good performance on Mac and PC.
 
Thanks david

I'll wait the guide about how create a LUT from program like Finesse from a kind forum user

About Quicktime :I understood that quicktime is slower than windows isng avi , but basically you are saying that at the moment no way to have realtime playback on a 2k using active metadata?

Sorry but i am asking again because i kind of remember that i did some test in the past exporting from redcine at 2k and play it back at 2k in realtime...and now i have reinstalled everything using Leopard so maybe i changed something... but i might be wrong...

Thanks

Jeff, my Sony Bravia 52 inch is supposed to be 10 bit panel with HDMI version 1.3a connection. How do you think we can utilize these features?

On the PC, it's as simple as using the proper nVidia or ATI card with HDMI 1.3 output and there are 5 or 6 of those to choose from.

As far as on the Mac, the only option right now would be the ATI 3870 card, but I haven't worked with one enough to know what it will do. I say that if ATI claims it will output full 10bit over the HDMI port, then give it a try. Not only does the card need to support 10bit HDMI output, but the Mac ATI drivers need to provide for the extended color support beyond 8bits/channel as well and I'm not sure that they do.

Upcoming nVidia and ATI cards targeted at both the Mac and PC will have the DisplayPort connector, which is essentially an upgraded DVI-DL system, but it supports higher resolutions and deeper color. Some monitors on the market already have DisplayPort (like the HP DreamColor) and I think there are a few oddball video cards as well. I'm expecting some DisplayPort options from Apple with the next revision to their Mac Pro systems and I think we can expect to see some new Cinema Displays -- Finally! The new Intel "Nehalem" CPUs were supposed to start shipping by the end of this month or early October (to OEMs), but there are lots of rumors going around now saying that they are delayed slightly to the end of the year or even January. So I'm starting to think we won't see new options from Apple until MacWorld in January.
 
Gabriele and others, we have had a Tech Note explaining how to export a 3D LUT from PPro from stacked color effects for a couple months: https://www.cineform.com/products/TechNotes/3DLUTGeneration.htm. In addition to the Tech Note we'll have a video tutorial in the near future.

It doesn't matter whether you use Color Finesse, PPro's color features, or CineForm's color correction, you can export the stacked color adjustments that are applied on the PPro timeline to an Iridas-format 3D LUT that we use for our Active Metadata controls.

It should be RT on most highend Macs, just that QuickTime is crippling Macs from doing much more, as equivalent PC can near play 4K with Active Metadata in real-time. A 2K 4:4:4 sequence typically only requires a fast dual core without Active Metadata, and about 20-30% more CPU load with Activate Metadata (which is N-way threaded, so it scales well.)
 
David, have you guys started looking at the new Canon 5D Mark II? I wonder if video can be captured from its HDMI port with less compression and better color sampling? The camera apparently records H264. Would there be any advantage in transcoding that H264 to Cineform or any other intermediate codec for editing in timelines?
 
I'm sure capturing the HMDI feed would work fine (but does it have burn-ins on it?) Converting the H264 to CineForm is a good idea as H264 is a pain to edit, the issue today is it isn't wrapped like an AVCHD file so HDLink won't convert it (yet.)

I don't know... can you guys investigate this and see what's up with this 5Dm2? If you guys could offer a way to grab a high-quality signal from the new 5D's HDMI port, you could probably sell it like hotcakes.
 
David, I'm wondering what happens once the trial for prospect4k expires, will one still be able to edit in cs3? Is encoding the only thing that expires?

Thanks

No, sorry the entrire editing mode will expire. Your project will revert to desktop mode if you don't purchase Prospect 4K. So you lose a lot of performance, I/O options and all the Active Metadata controls -- basically you get the stock CS3.
 
What is the simplest way to get a nice default look with Cineform?

What is the simplest way to get a nice default look with Cineform?

Davids, Here is how I used to work with R3D files. How do I accomplish the same goal with Cineform? This was the simplest way we've found to get a nice default look with the most information:

1. Open EVERY file in RedAlert
2. Turn on histogram
3. Choose a color space. RedSpace
4. Adjust any problems such as missed whitebalance, or tweak the color.
*5. Adjust the "Exposure" (finer control over ISO) or ISO settings until the footage is spread maximum over the latitude without clipping.
6. Export

How do we do this in Cineform? Imagine we set the ISO to 1000 for focusing purposes in low light. The image looks fine in RedAlert when we change the ISO to 320... But it's noisy at 1000...

But we've bypassed RedAlert altogether when we convert to Cineform... In the following doc you show us a screenshot of File metadata:
http://cineform.com/products/TechNotes/CineFormRAW-PPro.htm

You give us: Gain, Temp, Tint, Red, Green, Blue, Saturation, Gain, Blacks, Gamma, preset look

But I don't see a way to adjust exposure/ISO back to 320. How do we use these settings to get back to 320? the darker cleaner image we wanted but leveraged the ability to change metadata in order to be able to focus in low light...

That was key metadata we wanted to be able to adjust in post. Have you already automagically done something behind the scenes and haven't exposed the control to us yet?

Oh, that is sexy!

David, can you guys order a 5Dm2 and see if you can make this work? Maybe Canon would send you guys a body?

We got it working today (the file conversion part.) All you need in to do register MP4Spitter.ax in C:\Program Files\CineForm\Prospect4K and have CoreAVC installed (although CoreAVC may not be needed,) and the Canon 5D file convert very quick to CineForm AVIs using HDLink. You can use -0.1% speed shift to fix the 30.0fps to 29.97.

We automatically handle that stuff. We switch off all gain in the SDK (ISO 1000 = digital gain nothing more) and convert the RAW sensor data to a CineForm file. From the CineForm AVI/MOV you can manipulate the Active Metadata as you need during your edit.

So I can accomplish my goal by toggling the gain down until i'm happy with the noise/level? No wait you said it's switched off. so essentially gain is at zero (320 ISO)
