Year ???

Is there a reason why it is not a plain date ? author  TomT0m / talk page 20:28, 14 January 2018 (UTC)

Start date? End Date?

Shoudn't this property have a start and end date? What Exactly defines the beginning and end of a film production--Shisma (talk) 13:24, 26 August 2018 (UTC)

• It's the date production was completed. The property can be useful for works that have been published much later.

production? creation?

What's the difference from inception (P571)? --Infovarius (talk) 14:51, 6 March 2019 (UTC)

• Inception is before. Are there items that use both? --- Jura 13:51, 10 March 2019 (UTC)

Pre-production, production, post-production

Should all three stages be included in this property? Or should we only refer to the actual production and everything right until publication, i.e. include post-production only?

Regarding films. See en:Template:Filmmaking

• Development: Ideas for the film are created, rights to existing intellectual properties are purchased, etc., and the screenplay is written. Financing for the project is sought and obtained.
• Pre-production: Arrangements and preparations are made for the shoot, such as hiring cast and film crew, selecting locations and constructing sets.
• Production: The raw footage and other elements of the film are recorded during the film shoot, including principal photography.
• Post-production: The images, sound, and visual effects of the recorded film are edited and combined into a finished product.
• Distribution: The completed film is distributed, marketed, and screened in cinemas and/or released to home video to be viewed.

Regarding music. See en:Template:Music production

• Development: Ideas
• Pre-production: Process whereby a recording artist spends time creating and refining their musical ideas. The artist thus produces a song's demo recording, or rough draft, in order to pre-establish the song's creative premise. This reduces the time and money spent in expensive studios. The goal is to enter into the major recording phase of production with the basic and most promising ideas having been already established.
• Production: Engineering, recording.
• Post-production: Techniques used in music post-production include comping (compiling the best portions of multiple takes into one superior take), timing and pitch correction (perhaps through beat quantization), and adding effects. This process is typically referred to as mixing and can also involve equalization and adjusting the levels of each individual track to provide an optimal sound experience.
• Publication: Release

So, summarily:

• inception (P571) = development processes
• production date (P2754) = filmmaking (Q932586)/music production (Q959049) + post-production (Q648877).
• publication date (P577) = release + product distribution (Q867147)

So the only question is where should go pre-production (Q342868) — inception or production. Solidest (talk) 16:35, 27 May 2022 (UTC)

Or maybe inception should only cover pre-production, and the object does not "exist" yet in the development process? Solidest (talk) 16:43, 27 May 2022 (UTC)
