I Can't Change Bootanimation

Hello from a few weeks unsuccessfully trying to change bootanimation.Unfortunately, none does not work I also tried to install the application Bootanimations of JRummy Apps Inc. and toollbox also the TWRP recovery flashable version but unfortunately nothing changed .I'm suspect in android 6.0 bootanimation files are located elsewhere but where ? How i can replace it ? thank you in advance for your answer
