Customize Profiles

Profile is an important part that defines the video output resolution, video output bitrate, and audio output bitrate for encoding. Furthermore, it will also affect the costing of encoding, storage usages of encoded video and the CDN usages while watching the VOD. 

BlendVision One allows you to apply the customized profiles or the preset into ProfileSets to configure the encoding for each VOD.

In this article, we’ll introduce the preset profiles list and the detailed steps on how to create and manage the customized profiles.

 

Before we start

  • In BlendVision One, the output formats of encoded VOD (such as resolution and codec) are defined by the ProfileSet you chose, and the profile is a part of ProfileSet.
    Please refer to VOD ProfileSets to help you grasp the relationship between profiles and ProfileSets.
  • Changes to ProfileSets/profiles (such as deletion or editing) won't impact previously encoded VODs. To implement these changes on your VOD, please create a new VOD and select the preferred ProfileSets.

These profiles already apply into the preset ProfileSets we provided. You can directly use the preset ProfileSets or apply these profiles into your custom ProfileSets.

 

Customized profiles

If you want to customize the profiles, you should create or edit a custom ProfileSet first, to access the Profiles list shown on ProfileSet’s creating page/editing page.

Then you can follow the steps in the following chapters, to create and manage the customized profiles:

Add customized profiles

In order to create a customized profiles, please follow the steps below:

1. Press the “Add Profiles” button displayed on the Profiles list at ProfileSet's creating page/editing page.

2. The dialog window “Add profiles” will display, then you can start to set up the configurations of new profile:

  • The video codec (H.264 or H.265) will be blocked by the configurations of ProfileSets. If you want to change the codec, please refer to Customize ProfileSets to change the “ProfileSet Configuration”

3. Set up the basic configuration for the new profile: 

  • Name: enter the profile name that will display in the profile list. (up to 30 characters)
  • Resolution width: it defines the number of horizontal pixels for video resolution. Enter an even number between 128 and 4096.
  • Resolution height: it defines the number of vertical pixels for video resolution. Enter an even number between 128 and 2304.
  • Video bitrate: it defines the amount of data transmitted or used in video stream (kbps)
    • If the video codec is H.264, enter a number between 60 and 60000.
    • If the video codec is H.265: enter a number between 60 and 45000.
  • Audio bitrate: it defines the number of data transmitted or used in audio stream (kbps). Enter a number between 24 and 384.

4. (Optional) You can set up advanced settings for the new profile if needed: 

Note: these values will be limited by the video codec of ProfileSets.

Delete customized profiles

Before deleting profiles, please confirm the cautions below:

  • The preset profiles are not allowed to be deleted.
  • Once the customized profile is deleted, it will be unable to be restored and you cannot apply it into ProfileSets anymore.
