I try to convert video 1080p 50fps to 25fps by Bd Rebuilder
I choose "IVTC drop down"in Setup , but output video still 50fps
I do something wrong? and how?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

IVTC = "Inverse Telecine" is only useful to revert the Telecine conversion of cinematic Film (24 fps) with slight slowdown (23.976 fps) to NTSC television (29.97 fps).
NEVER try to apply this to PAL based video frame rates (25 fps)!
Furthermore, there is no Blu-ray video 1080p with 50 fps. With a height of 1080 lines, Blu-ray video must be encoded in interlaced mode (no matter if the video content is interlaced at all). So you will have 50 fields per second weaved to 25 frames per second. -
You are likely confusing fields and frames, which are different. "fps" means FRAMES per second, and not FIELDS per second.
50 FIELDS per second 1080 video is possible for BluRay, but NOT progressive. If you have 50 fields per second then this is 25 frames per second, which is 1080i - interlaced, NOT progressive. So I would guess that if you tell tsmuxer that you have 1080i video at 25 fps (fps means FRAMES per second to tsmuxer) it may mux it correctly. -
If this video is really 1080p with 50 fps, then it is not Blu-ray compatible; you would have to re-encode it to either 1080i with 25 fps or 720p with 50 fps if Blu-ray compatibility is necessary.
If you only want to play any arbitrary M2TS on a PC, tsmuxer should be able to create it if you don't try to change the framerate, I believe. But I have no practical experience with it. -

your footage is flagged as interlaced, however it is 25 frames per second.. do your re-encode and try it, the out come should
be correct..for whatever reason 25 frames per second gets flagged as interlaced even if its progressive. -
Because it is required by the Blu-ray specs, 1080 video is mandatory to be encoded in interlaced mode. Therefore, x264 supports "fake interlacing" to encode progressive video efficiently and also Blu-ray compatible.

ningnong132 - Is your video from a camcorder? You definitely need to tell us if that is the case. Camcorders can record video in formats that are not allowed by BluRay. If this is camcorder video, then you should make an AVCHD disc out of it. I'm not sure that BDRebuilder can convert camcorder video. It was intended to be used on BluRay compliant video, which is often not what camcorders make.

x264 is a program, an encoder, used by many GUIs you may see as "program".
But ... you say the original video is from a Blu-ray disk. So it must have been Blu-ray compatible already. So the reason of the problem is probably not in the original video material. Rather in using BD Rebuilder wrong... -
Yes! Problem is Bd-Rebuilder
I try old version everything is OK!
Thank You
