CAN SOME BODY TELL ME THE PROCESS OF "How the feature film is prepared for copositing in s/w like combustion, what should be the i/p resolution (if i want the output for 2k res. feture film), how it is converted from video tape to high res. editable format.

Hello.

Well, there is a standard workflow....

1) Take the Filmstock and SCAN it to create high definition files. This procedure requires specialized equipment, such as a film scanner. Yoiu can read MORE about the process here: http://www.cintel.co.uk/ (Click under TECHNOLOGY - and download some of their white papers.

2) File Types: Combustion can accept the following high res file formats:

HDTV 720/30p
Frame size: 1280 x 720
Frame asp. ratio: 16:9 (1.778)
Pixel aspect ratio: 1
Frame rate: 30 fps
Field order: no fields

HDTV 1080/24p
Frame size: 1920 x 1080
Frame asp. ratio: 16:9 (1.778)
Pixel aspect ratio: 1
Frame rate: 24 fps
Field order: no fields

Film Full Aperture
Frame size: 2048 x 1556
Frame aspect ratio: 512:389 (1.316)
Pixel aspect ratio: 1
Frame rate: 24 fps
Field order: no fields

Cinemascope (Anamorphic)
Frame size: 1828 x 1556
Frame aspect ratio: 457:389 (2.350)
Pixel aspect ratio: 2
Frame rate: 24 fps
Field order: no fields

Academy Aperture Cineon Full
Frame size: 3656 x 2664
Frame aspect ratio: 457:333 (1.372)
Pixel aspect ratio: 1
Frame rate: 24 fps
Field order: no fields

Academy Aperture Cineon Half
Frame size: 1828 x 1332
Frame aspect ratio: 457:333 (1.372)
Pixel aspect ratio: 1
Frame rate: 24 fps
Field order: no fields

Or a Custom Format Setting: You can create a custom format instead of using one of the standard formats listed previously. Use the Custom format option to set exact values for frame size (and thereby frame aspect ratio), pixel aspect ratio, frame rate, and field order. Note: You cannot save your settings as a preset; you only use it as you make solid footage or a branch.

3) After scanning, the files are very large and can be very difficult to move around - therefore a specialized network is used, called a hippi network. For more info, you can read about it here: http://hsi.web.cern.ch/hsi/hippi/

4) Basically, the images files can be opened and worked on in Combustion. You can apply color corection, special effects, keying, 2D and 3D effects, text, paint, masks, etc. etc. etc.

5) With LARGE file sizes such as the above, you DEFINATELY want to take advantage of network rendering (BackBurner) to distribute the task of rendering..

6) After all the files are fully rendered, the final image sequences must be shot BACK to FILM: To do this, a specialized FILM RECORDER is used, for example, a CELCO digital film recorder (see: http://www.celco.com )

Does this answer your question?

Keep Combustin'
