Initial meeting to talk about ideas and the purpose of the film, its intended audience, style, running time, delivery format etc.  A treatment is produced taking in to account all the items mentioned, this gives a reference to work to throughout to production process.
A script is then produced. The exact form of the script will depend on the approach, a documentary style film may produce a script that is simply questions to be asked during the on camera interview process, the answer to the questions providing the films narrative. A more traditional approach may mean a solid voice over script along with a shot list.

At this point we reach the production stage, which normally means the start of filming.  This would normally include filming the bits that the film is about, perhaps an event or process, interviews etc. This can generally be the longest part of the production process making sure that everyone is available and ready to be filmed.

Once all the footage is gathered together along with anything else that may be needed (graphics, music, voice over recording etc) the editing process can start.  The time it takes to complete the edit can vary greatly depending on the film, a simple piece to camera (PTC on the jargon) would be very simple to put together, simply editing the recording down to its salient points adding graphics and some cutaway shots. An edit of a big event may take longer. As a rule of thumb (but as usual things are always different) one day of shooting will generally need two days to editing.

Once the film has been completed and signed off (checking everything matches the original treatment, graphics are correct, peoples names are spelt correctly etc) the film can be authored to DVD or exported ready for use on the internet or any other digital device. In most cases the film is uploaded to either youtube or Vimeo for playout through an embedded link on a website/facebook etc. We can also archive the the film so it can be added to or re-edited in the future.
