Looking at Ayngaran's very good Blu-Ray shots, authored from DPX files, I'm wondering from what sources Hindi Blu-Rays are authored. Are they authoring them from DPX files? And in the case of pre-DI films, are they scanning the negative? Interpositive?

Hindi producers are backing thier films onto a D5 source. This is a HD tape format with certain limitations. Once the films are backed onto D5 tape, they delete the DPX source.

They should be backing thier films onto HDcamSR, but this is a very expensive process...and the format is not widely recognised in India.

Because of my technical know-how (and very powerful friends in the industry) a majority of Tamil producers are now saving the DPX files. Since we have the DPX files we do not need any tape formats for new feature films. I should point out that having the DPX files is not enough to ensure quality. You need additional files, a specialist, and the film-makers co-operation to ensure all the colours, contrast, blacks and film grain levels truly represent the original vision (as seen on the big screen).

For old film projects like Kandukodian, Jeans and Chandramukhi we will be using 4:4:4 HDcamSR source - which we created directly from the original camera negatives scanned at 4K resolution!

Since some of the older movies are going to be scanned at 4K resolution would you be able to store them on HDCAM-SR without loss in quality?

What is the case for hollywood movies, how are they backed up. Do the producers prefer DPX files or HDCAM-SR.

Scanning at a higher resolution and downsampling to the target resolution (in this case, 1920x1080) results in a better transfer than just scanning directly to the target resolution, if everything is done properly.

4K can only be stored in full quality as 4K files. HDCAM-SR is limited to 1080p 10 bit resolution. Hollywood films are stored as DPX files, cut original negative, color separations and HD versions (HDCAM-SR these days).

HD tapes used are not analogue. They are all digital.

All the recent past most recent past like 3 years back films are taken back up on HDCAMSR tapes in bollywood. To the best of my knowledge all the films are now getting transferred to HDCAMSRW tapes.

The back cover of the Magadheera DVD mentions a D5 source. Are Telugu producers doing the same thing? I saw the screencaps of the Blu-Ray and wasn't particularly impressed, so I think I'll just stick with the DVD.
