MPEG2 50fps

[Incast]

Firstly i'm sorry if this in the wrong forum but it doesn't fit nicely in TMPGEnc and CCE. Also I apologise if this is very obvious but i have performed various Google searches and forum searches to try and find this answer, is MPEG2 50fps possible?

I am attempting to recompress an MPEG2 source 25fps interlaced using bob deinterlace techniques to create an MPEG2 file 50fps progressive. However, both CCE and TMPGEnc report 50fps as being impossible for MPEG2 yet i have read numerous posts with people claiming to have MPEG2 50fps. So, is MPEG2 at 50fps possible and if it is how do i do it?

50 fps mpeg2's?
never seen...
i also think tv's can't handle those...
but maybe someone who knows more about this can give 100% sure information

Dont worry i found out that in TMPGEnc that you had to change to Main profile and high level in the video options to do it. Thanks for your input anyway.

MP@ML (ie, dvd spec) doesnt support 50fps, which is why you need a HDTV style level to do it.

What's the reason for doing this? I don't see any advantage of encoding the style you want.

I saw a web site about this somewhere recently -the ultimate de-interlace trick I guess.

bobbing gets you no extra information whatsoever. it's the best you can do to even retain the amount of vertical information the interlaced video gives.

smart bobs are slow as hell, and if you're going MPEG-2 anyway, just encode interlaced and reap the 80% saving in bitrate (as compared to 50fps).

if you're viewing on a PC, theres players out there that will bob on playback for you, and if you're viewing on a TV there's no problems (provided the field order is correct)
