Blueray result much worse than actual rendered MP4

Hi there,

As far as I can tell from the defaults in DVDachitect a Blueray apparently has a framerate of 24?

My film has a lot of fast moving action in it like rotating with a gimbal around a subject, so you can say I did some extreme fast pans. Now I filmed it at 60fps so the original footage looks great, what would be the way to go to get this onto a Blueray without having it look like a total epileptic-fit-causing, flickering mess? :D

Or is this just something that is not possible? I can hardly imagine that Hollywood action movies don't have scenes in them that have extreme panning, do they put tose movies on Blueray using a different framerate or something?

Marcel

DVDA and the current BD standard doesn't allow for 1920x1080 @59.94fps. But, you can render it to 1280x720 59.94p and that will look much better.

Does that mean hollywood action movies are also rendered in 720p instead of 1080p when they have a lot of critical scenes?

I don’t think so. They are usually 24p and action scenes have a lot of motion blur added or are shot with a longer exposure.

Not quite. You should be rendering 59.94i, a legal disc format, not 24p which is for film.

It is the correct Bluray template for your source.

Oldsmoke, if you watch "Gladiator", they did just the opposite on action scenes. They used a high shutter speed with no motion blur.

Hmmm...interesting, motion blur, faster shutterspeeds....Does anyone know a good source that explains stuff like this, I’ve been struggling with it for years to be honest. So watching a 24p video play does not always mean you see it flickering when there is a fast pan or gimbal shot with lots of movement, there are ways of masking that in post? Or do you add the blur during filming? Also struggling with slowing shots down and the results it has on the rendered video, I often use my Gh5 for filming shots with tripods or handheld details in 50p since we’re in a PAL country but I also use my Galaxy S9 for gimbal shots in 60p, because it simple doesnt have 50p. I guess it doesnt matter nowadays though since a modern TV or the internet can be fed anything. So I might as well set all my devices to 60p (or 30p for my drone) right? Vegas manages to render everything into the project framerate but there are so many points in the whole process where the framerate is changed, I’m a bit confused with it. Can DVD architect change a 50p video into 24p without the weird effects or should one film, render and make the Blueray in 24p to have a good result?
