25fps to NTSC Blu-Ray…
I’m looking to get a video that plays at 25fps onto a NTSC Blu-Ray, and when I encode to anything other then 25fps, I get stuttering and ghosting – no big surprise.
Any tips from anyone on how to eliminate this as much as possible when encoding?

Hi Eric,
Pasting from my post below with some additional personal experience.
Your best options are Twixtor or a plugin from Video Copilot (free but very render intensive).
Twixtor will do very well in many cases. The downside (other than having to buy it), is that you may see artifacts in some instances. For example, I noticed that shots made in front of LCD screens (like a finger on a phone, or a hand in front of a TV) will have a smudge around them. The software can also have problem creating frames from low shutter shots. Overall, the conversion looked beautiful.
Video copilot uses a similar technique, but the render times were sometimes unbearable… On the upside, it’s still free.

You can do this retiming in After Effects without buying Twixtor.
After Effects includes more advanced frame blending options than does Premiere Pro, so you can avoid the ghosting problems that come from the simple “frame mix” variety of frame blending. The Pixel Motion frame blending setting in After Effects uses a similar technology to that in Twixtor.

Thanks for your answers. I’ll give them a look and try.
For now, I just put the video on a separate Blu-Ray that was set up for PAL. It seems to play fine on my Blu-Ray player even though I’m here in the NTSC land.

Eric,
An easier way could be to simply interpret and export as 24p, the difference in speed and audio likely won’t be noticed.

I thought of that too, but I still got the ghosting effect.

Well, it came up recently in a previous post. It looks like Premiere now blends no matter what… Maybe be Todd could chime in on that.
Do double check that frame blending in unchecked when right clicking on the clip.
You’ll have to interpret and export in After Effects instead.
