Well actually this in not my first rip. Yes I know delay means silence but silence doesn't means skipping logos. Both Divergent and valerian have this kind of problem in which my delay works perfectly without abruptly skipping logos. I don't know why it is happening in this. Also i can't ditch english audio which is atmos. Its looks like i have to do it myself. Thanks You are not allowed to view links. Register or Login and You are not allowed to view links.

There is (+)19280 delay in hindi audio  and Video Fps needs to change to 23.976/24 in stretch by column for video in mkv toolnix.
You can keep eng audio as well,  just add 23.976/24 in stretch by column for the eng audio.
Hindi BD is not dubbed according to International Summit BluRay so if you download other region 24fps BDrip then summit logo will be already missing.
You can also give (-)19280 delay to eng video & audio both and no delay in hindi audio if you want to remove logo completely.
Use MPC-HC player, it plays logo mutely and doesn't skip it. Hope this helps.

Thanks You are not allowed to view links. Register or Login first one didn't work but second one works perfectly. By giving delay to video actually works in which i have to remove logo. Yes you are right i have the movie with 1:33:12 length that's why I have requested the audio with same length.
Anyone can give you 23.976 fps audio by converting it thru Megui but you would lose the audio quality.
To achieve 23.976 audio, 24fps hindi BD audio needs to convert to 25 fps first and then that 25 fps audio needs to convert again to get 23.976 fps.
So you can imagine how much quality you would lose by converting twice so its better you use untouched audio and don't waste time & energy in making it perfect.


Read the posts near these posts.. to understand more about that audio in question. You are not allowed to view links. Register or Login is always there for help.

Or you may convert it via ffmpeg

^ 25 to 23.976 and vice versa is easy via megui.
for 24fps to 23.976 try.. ffmpeg.

here are some commands (credit $id bro)

23.976 to 25

-af atempo=25025/24000 -c:a eac3 -b:a 640k

23.976 to 24

-af atempo=24025/24000 -c:a eac3 -b:a 640k

25 to 23.976

-af atempo=24000/25025 -c:a eac3 -b:a 640k

24 to 23.976

-af atempo=24000/24025 -c:a eac3 -b:a 640k

here output format is eac3 with 640 bitrate.
you may change according to your needs


If you still want to do it via megui.. the first result is a 10 year video.. should be same now :P
