Frequently Asked Questions

Why Choose RedLab?

We have more experience processing, coloring and onlining REDCAMERA footage than anyone else in Toronto. This will save you money. REDLAB also receives alpha releases from the RED company before anyone else in Toronto. REDLAB is an alpha tester for the RED ONE camera so we are at the forefront of the knowledge base. We own camera serial numbers 0050 and 0051 and were the first to use the RED camera in Canada. We were also the first company to process RED ONE camera footage for theatrical and broadcast release.

What Is The Red One Camera?

The RED ONE camera system is a digital acquisition tool for motion pictures. It has a 12 megapixel CMOS sensor that records data to compact flash cards or an on-board hard drive. It can record up to 120fps in certain resolutions. The image quality and latitude is similar to that of 35mm motion picture film stocks. The camera uses a PL mount so cine lenses can be used to achieve identical depth of field to that of super 35mm.

What Is An R3D File?

R3D is the extension of the proprietary file format generated by the RED ONE camera. It is a RAW compression type affording it an incredibly high fidelity range and image quality.

What Are 2K And 4K?

2K and 4K simply represent resolution sizes. 2K has approximately the equivalent resolution of super 16mm film and 4K has approximately the equivalent resolution of super 35mm film. RED 2K has 2048 pixels by 1024 pixels and 4K has 4520 pixels by 2540 pixels. 4K is 400% larger than 2K. You can fit four 2K frames into one 4K frame. 35mm film has an approximate maximum resolving power of about 5000 lines of resolution when converted to a digital scale.

Why Is Red Post Not As Simple As HD Tape Post Production?

Shooting with a RED ONE camera may seem effortless on set, however, to harness the full quality of the R3D file a number of post processes must happen that are extremely processor intensive before the online editor can use the files. The post processes that are performed include decompression of the R3D file, decode, debayer, demosaic, sharpen and render. REDLAB uses a custom built and custom scripted render farm to accomplish almost real time processing of the R3D file in full quality. HD tape based production may be somewhat simpler, however, it is more time consuming, more expensive and will always yield lesser quality and image range than file based online systems using native camera files.

Do I Really Need Full Quality To Do My Offline Edits?

No you do not. In fact, it is cost prohibitive to request full res files of the rushes. This would be the same as an editor using DPX or CINEON files to edit. It would take up far too much space and CPU power to edit this way. REDLAB takes the R3D file with timecode and prepares an offline version for the editor. This can be tape based or digital data. Common editor requests for file types are PRORES HD and SD as well as DVCPRO HD. REDLAB can prepare Avid compatible files for use in offline and online Avid editing.

Once I Am Finished My Offline Edit, What Is The Next Step?

The next step is to do a simple conform of your edited footage to prepare for a color grading session. This conform should be done using the original R3D files and a EDL or XML from your offline edit. REDLAB offers flexible options for conforms and color grading. We can do this in house or prepare your selected footage for onlines and color grading for out of house jobs. Typical file types for color grading out of house include DPX or CINEON files. Please see our services page for more information.

Why Can't I Just Colour Correct The Offline Files REDLAB Provided Me? They Look Great!

You can color correct your offline tapes or your compressed quicktime files. You would now essentially be performing a tape to tape transfer and not utilizing all the color information and latitude available on the original R3D files. If you color correct the offline files you are most likely grading an 8bit file which holds 256 shades of gray. The R3D file holds 12 bits of color information or 4096 shades of gray. Color correcting your offline files may offer you 1-2 stops of latitude with very little shadow detail. Color correcting the R3D file has a dynamic rage of 66db or almost 12 stops allowing you to see well into the darkest areas of your shot. It has been said that the RED ONE camera holds more latitude that 5218 motion picture film.

How Much Better Is An R3D File Than A DPX File?

It may be that you wish to color correct your RED footage at a facility you are familiar with. In this case we can prepare DPX or CINEON data files or lay out to HDcamSR tape. However, you will lose some amount of latitude and color depth when converting to these formats. DPX is a 10 bit format that has about 1024 shades of gray. R3D files are 12 bit and contains 4096 shades of gray. This difference becomes crucial when trying to isolate colors and tones in the color correction process. HDcam SR is 12bit but it is compressed at a ratio of 4.2:1 and only has 1920 x 1080 lines of resolution. An R3D file has 4520 x 2540 lines of resolution. This is greater than 4x that of HDcam SR so resizing and enlargements in color correction will be less noticeable than on HDcam SR.

Why Can't I Just Use The Proxy Files That The Camera Creates For My Final Images?

The camera does create a set of proxy files automatically. These files are of lower quality than a properly processed R3D file. When proxy files are screened on large TV's you can see jagged edges in the image as well as banding in gradated areas such as skies. The color space of the proxy files is only 8bit so it is unsuitable for effects work and may not meet broadcaster specifications.

What Are The Uncompressed Data Rates For a 4K File?

Approximately 400MB/sec for a 4K uncompressed file. Approximately 100MB/sec for a 2K uncompressed file.

My Project Is Done! How Do I Deliver The Original Files To My Client?

REDLAB archives the original R3D files to LTO3A digital data tape. LTO has a shelf life of 30 years when stored in ideal conditions.

Is RED Really The Future Of Digital Media?

We think it is. Contact Us for a workflow demo to see for yourself.

Does REDLAB keep my DATA indefinitely??

No. Although we back up your DATA in several places including LTO data tape, unless we are requested to keep the data we will delete all data should the client not wish to pay to back it up for longer than the projects working duration. We will NOT delete any data without direct communication between ourselves and the production company and or the editing company. In most cases LTO data tapes are purchased by the production company and used for original camera data archiving. An LTO 3A tape baked up by REDLAB costs $250 and holds 400GB. This is about equal to 2 hrs of shooting.
