Re: [Avid-L2] 29.97 and HD / RANT

There has to be a video describing these frame rates and what they look like.

When I shoot a film, we discuss the deliverable.  But usually it's 24P or 23.98.  Except for Slow-mo where we shoot 120 fps.  On the Canon C300 we shot 23.98

To me, one aspect that is missing from this conversation is the other reason to choose a specific frame rate other than for technical reasons.

Yes we have to deliver specific frame rates for specific mediums (network, streaming, theater, web, IMAX, gaming, etc…) but I believe they are still room for director/producer to decide to shoot one frame rate over the other because they want to give a certain look to their content.

Maybe the most common example is for cinematographers to shoot 23.976fps in the USA even so they know their project (documentary, film, etc…) will end up being watched at 59.94i fps on television… adding 3:2 pulldown will still give you the "feeling" from playing at 23.976fps when it actually is 29.97fps.

Another example is for gaming. I understand gamers want to feel the closeness to the actions. They want to feel being part of the actions. Creating a game at high frame rate and playing it back at 60fps will give you that feeling of having the action happening "right now" in front of your eyes… what some people call "soap opera" effect.

23.98p if you are attached to pull-down, or want to save 5% on storage, or for international delivery.

You are obviously talking from the perspective from someone in the USA

24.0p only for cinema, but this will be slowed to 23.98 for video delivery.

…or not if you are delivering for the web/internet… no more "old constraint" in the digital world… 

29.97 for video. Period. This may be delivered interlaced, but don't count on it.

Like JB mentioned, I believe most networks still deliver an interlaced signal, no matter if you master progressive or not… still a progressive master will be higher quality no matter what happens down the road...

25.0p for video almost everywhere other than the US

Not true… look at a broadcast television system map in the world… https://en.wikipedia.org/wiki/Broadcast_television_systems

All North America, the Carribean and some South American countries are using the same frame rate than the USA

So if you say 24p, I know you mean 23.98p, unless you are shooting for cinema.

And you say 30p, I know you mean 29.97p. 

If you say 25p, I know you mean it, and are working in a country that doesn't have this problem. ;)

I find your guessing a little confusing… but if it works for you great!… personally I prefer asking the question clearly from the start and make sure people understand the consequences of choosing a frame rate over another one than guessing what they mean…
