Video length Automatically increase after encoding

Video length Automatically increase after encoded with Megui
OS :- Windows 7 X64 SP1
MegUI :- MeGUI V 2050 X86
Note:- Normal X264 replaced with 10 Bit depth x264 for Hi10P Encoding
Problem
until Now it never gives me any problem but from yesterday it suddenly started to give me problem about length of video becoz of that audio & subs did not sync with video becoz of different length (i double checked the encoded audio & source file for length it matches perfectly but MEGUI encoded video's length didn't matches with source file)
I usually Demux file using mkv cleaver so i get chapter, subs , audio(Encode audio with foobar without any problem) separately.
then MKV file with only video in it goes for encoding in megui & then encoded video ,audio, subs & chapter muxed with mkvmerge gui

I would re-try one of your older files that converted properly. It may be your problem file has a 'problem'. If all files do the same thing, then you would likely have to trace down what part of the operation caused the sync problem.

Or someone here may notice something in your posted data.
