- In the Transcoder page, click
. The Add New Profile window is displayed:
- Select the desired Profile type - MPEG2, H.264, H.265 for video profile and AAC for audio profile.
- Enter in the desired fields in the Profile configuration (see table below for additional parameters).
Selecting a specific configured Preset will fill in the settings automatically or alternatively leaving the default as Custom requires you to configure it by yourself. - If you want to configure the Advanced options for the H.264 profilevideo profiles, select Advanced options and fill out the respective fields (see table below for additional parameters).
- Click Apply.
The newly configured profile is created and appears on the screen.
