I have enabled Dynamic Media and followed the Installing and Configuring Video Transcoder with FFmpeg instructions(https://docs.adobe.com/docs/en/aem/6-0/administer/content/assets/video-transcoder.html). In the SETTING UP THE DYNAMIC MEDIA FFMPEG TRANSCODING SERVICE section, the following is added to the arguments for the workflow step: profile:firefoxhq,profile:hq,profile:flv. Are these needed if we have specified a Processing Profile on our video folders in the DAM that uses the out of the box Adaptive Video Encoding Video Profile or are both needed?
