FOR Directorik i am submitting all that in black so that he can read and comment on that
Dear Freinds i have a habiit of asking one question from several people to cross check
so i contacted many pro houses and i got reply from one of them which im posting here
> 1) If we want to transfer our movie from digital (1080i) to 35 mm obviously there will be some loss because for cinema the requirement is of 2k and
> 1080i is just 1k.So is there special settings while production (shooting) too to help in post production?
The expression 1080i does not refer to a Resolution of 1k, 1080i means 1920x1080 pixels with interlaced recording.
If you have a HDV Camera from Sony or Canon you have a camera which can record in 1080i. The resolution is OK for a transfer to film.
There are HD and HDV cameras with a recording mode of 720p which means 1280x720 with progressive recording.
More ideal for a transfer is recording full image frames. This is called progressive recording and is indicated with p. The motion reproduction of a film recorded in progressive mode is more like film than interlaced. Interlaced has more the typical smearing effect in motion, progressive recording has more the typical shuttering of film. Both are not perfect, but p is more like film and therefore often preferred.
There are also camera which offer a “frame mode” (The Sony Z1 HDV for instance) this is not a true progressive mode and should not be used.
General remark about resolution and transfer:
Any image can be transferred to film, no matter the resolution. Also the smallest miniDV cameras are used for transfers from time to time. The question is more what quality you expect. An image in SD resolution (Standard Definition 720x576) will never be entirely sharp on the big screen, the resolution is just not good enough. Still you can achieve good results and exciting and beautiful films with this resolution. The question is not just the resolution but:
1) How you handle it on the film set
2) How well you work with the lighting
3) How strong compression artefacts are visible (this makes the image look synthetic and “videoish”
4) How much the colors are compressed in the system you use
Example:
HDV is an HD format and quite good what concerns resolution, but the colors are very strongly compressed. Digital Betacam on the contrary only has SD resolution but much better colors. In the end it’s ot clear which image is “better” but many would prefer Digital Beta even though the resolution is smaller.
There are many factors which make a good image.
Every camera has it’s own specific characteristics and so special settings which are ideal for transfer to 35mm can be evaluated. On our website

you can find settings for some different cameras and also general recommendations on how to receive good results for transfer (valid for any camera).
> 2) Can you tell me which is the best HD CAM available (Not more then 1000US dollars) which can keep the maximum quality while transfering from
> digital to 35mm
* HDCam is the name for the professional HD Format created by Sony. It has a resolution of 1920x1080 pixels and a color quality of 4:2:2 (8bit linear). It is possible to shoot interlaced or progressive with this type of cameras. The HD format established by Panasonic is called DVCPro HD or DVCPro 100 and has a resolution of 1280x720 pixels with a color quality of 4:2:2 (8bit linear). It is possible to shoot in progressive mode with these cameras. The camera is also called Varicam.
You will not find any of those cameras for less than 50’000 US$
Remark: The expression 1k, 2k , 4k etc. refers to image sized with around 1000 pixels, 2000 pixels or 4000 pixels in width. Still there is more to it. 2k stands for a color depth of 10bit log or more. HDCam which is close to 2k in resolution (also about 2000 pixels in width) has only 8bit lin in color quality and a compression of 4:2:2
There are new cheaper HD cameras available:
Sony XDCam HD
Panasonic HVX200
These cameras deliver stronger compressed HD. This means that the resolution is as above, but there are more compression artefacts and the colors are quite compressed also.
These cameras cost around 10’000US$.
* The cheapest HD format is HDV:
The color compression is very strong 4:1:1 and generally there are compression artefacts as in DV.
The image looks like a DV image but more sharp, as the resolution is better.
The HDV format is basically meant for news gathering or semiprofessionals and amateurs.
These cameras also cost well over 1000US$.
* There are some more very small and very cheap HDV-type cameras on te market but the quality is very bad and I have no further info on what format they exactly record on.
Which format is “good enough” to transfer can’t be answered in an absolute way as it depends on what you expect.
In comparison to film it can be said that the HDCam and the DVCProHD format is about as good as 16mm film. In some ways HDCam/DVCProHD is stronger in other ways 16mm.
There are only a hand full of High End digital film cameras which come close to the quality of 35mm. The resolution to represent a 35mm image is at least 4k.
Also film needs to be represented with a color depth of more than 8bit lin.
You see there are many aspects to the image, not just the size in pixels.
> 3) Please guide me in detail about the setting and other factors which i should keep in mind while shooting. So that when i come at the post production
> level and transfer 1k to 35 mm the quality remains the same or falls the least.
You’ll have to go with what I explained above and educate yourself further by reading the literature and by doing tests.
Check the general recommendations on our website.
> 4) Any tips or instruction you want togive related to sound or sound recording?????
This is all a field of its own. We are not a sound studio you’ll

This is all a field of its own. We are not a sound studio you’ll need to ask elsewhere.
> 5) I am planning a 1 hour30 mins movie. What will be your charges including editing etc etc.
We can only make you a useful quote when you have a clear view of what the recording format will be and how you want to do the post production. Else this is much to vast and won’t help you much.
over here numbers like 1> are my questions.expert may comment on this and people like me might get some benefit from this
