Vídeo em PDF não funciona

Hi @Luana245350126qt8 

Sorry to hear about the trouble caused.

Try a couple of troubleshooting steps to see if that helps:

1- Navigate to Acrobat>Edit>Preferences>Security (Enhanced)>disable  "Protected View" and "Enhanced Security">OK>close and reopen Acrobat

Note: these changes are only for testing purposes. Once tested, please change it back to the previous setting. 

Go to Acrobat> Help > Check for updates and reboot the computer once (you must save all the work before restarting)

To download the patch manually, more information about this release is here: Release Notes | Adobe Acrobat, Reader

2- Navigate to Acrobat>Edit>Preferences>Multimedia & 3D content> enable playing of Multimedia and 3D content.

• Preference> multimedia legacy check the player option

Preferences>Multimedia Trust

In addition to this, please try all the troubleshooting steps suggested in the help article here: https://community.adobe.com/t5/acrobat-discussions/embedded-video-in-a-pdf-file-won-t-play-in-adobe-reader/td-p/11913858 

Thanks,
