Canon 5d MKII: 30fps to 25fps

[Gannjunior]

I would like to achieve a smooth video, since the problem of that conversion could be a not completely smooth video.

That is an OBJECTIVE evidence if you do that conversion using some commercial software.

I believe that avisynth could be better.

I hope to have formulated my question in the right way...

Any script suggestion?
Thanks

You could try using MFlowFPS for motion-compensated solutions. However, for conversions to lower framerates, the artifacts are probably not worth it. Have you tried using ConvertFPS' blend modes?

On what kind of display will your project be shown?

Are we simply talking about converting 30p to 25p?

Easy:
FDecimate(25)

Or to add motion blur and possibly make it smoother:
Source = FDecimate(25)
BVec = Source.MVAnalyse(isb = true, truemotion=true)
FVec = Source.MVAnalyse(isb = false, truemotion=true)
Source.MVFlowBlur(BVec, FVec, blur=15)

Change blur=15 to add more or less motion blur.
But then again, maybe I don't know what you are trying to do.

decimating (even with motion-blur) wouldn't be acceptible. it'd be jerky.

while mvtools are in the mix there, there's no harm using mvflow.

i'm not really up with the 5D workflow. some haxx0r out there needs to release a firmware to allow 25fps. it's not as if the camera isn't capable of it.

London, 20 October 2009 – Canon today announces that it is currently developing a firmware update to the EOS 5D Mark II to enable the recording of high definition 1080p video at 24 and 25fps. (http://www.dpreview.com/news/0910/09102003eos5dfirmware.asp)

I know that Canon announced a new fw with 25p but for is for 2010.

The reason i want to convert 30fps to 25fps is when i have to get PAL (i know that if everyone would have bluray there wouldn't be any fps problem...).
So it's important to minimize the lose of quality during the process.

I was speaking about "smooth" beacuse i noticed that the big problem of that kind of conversion is that the video converted is less fluid (i know that a bit is normal) in a too many evident way during animated scenes.

I do editing on 24"DELL U2410.

Thanks for your help guys.

You need mflowfps from mvtools2.

The results aren't perfect.


Nice you're getting 25fps via a firmware update - 25fps has been sadly lacking on video from point-and-shoot cameras for a decade! (always 60, 30 or 15fps!)
