If I create a Blu-Ray disk (DVD+R DL or DVDr) from a .mkv file that has 25 fps, will it play in my NTSC PS3? Or do I have to convert the video and audio to 23.976 using Avisynth scripts and then create the disc? The source files are the Star Wars movies in 1080p .mkv's FYI.

as long as you are using an HD set with hdmi the framerate shouldn't matter.

Actually it does matter. The 25 frame rate won't play in a NTSC PS3. However the 23.97 will.

I am having the same problem with the 1080p Star Wars. I did find a thread from Ryu77 talking about using AviSynth to convert to 23.976. As far as I can tell this will also keep the audio in sync. I'm not to sure how to handle the resolution in the script though. Any help would be greatly appreciated.

The following is is an excerpt from the Ryu77 post:

I used AVIsynth with the following script:

loadplugin("D:\AVI synth plugins\NicAudio.dll")
Video=DirectShowSource("D:\Video.mkv")
Audio=NicDTSSource("D:\DTS Audio.dts")
audiodub(video,audio)
AssumeFPS(25,sync_audio=true)
SSRC(48000,false)
AddBorders(0,132,0,132)
LanczosResize(720,576)

I then used MeGUI to convert my 1hr55min (23.976fps) DTS track to a 1hr50min (25fps) Dolby AC3 track.

This method can also work for PAL-->NTSC conversion. Just change the number in AssumeFPS from 25 to 23.976 and resize to 720 x 480 instead of 720 x 576.

Note: The mkv video file loaded in the AVIsynth script is a repacked Matroska file with only a video stream.

Guys, 25fps will play fine in a NTSC console. The movies in question I have too and all six work fine. Do not make them AVCHD structured, keep them m2ts.

Oh yeah, anywhere you see Ryu77 posting pay attention because he knows alot about this stuff.
