Adding Video & Audio Sources to an Encoder
Only one video and one audio source can be added to each encoder. Whichever way used to add an encoder, the same window pops up. By the help of this window a video and audio source can be added.
Adding Video Source
Encoder Name can be written to the left side at the buttom. After that by clicking 
button a video source window pops up it is shown below.
By choosing one of the sources and clicking OK button, a video source will be added to this encoder. If “File Source” is selected as video source , a folder browser window pops up. Any video file from local machine or network can be selected.
After adding any video source, all source information and parameters can be examined in “Source Parameter” tab. These information types and values vary according to selected video source . As an example The "Source Parameter" tab at the image is for "File Source".

By clicking 
button, an audio source can be added. It’s almost the same process with adding a video source.
Simply, by selecting any audio source and clicking OK an audio source can be added. Just like adding video source, if File Source is selected as audio source , a folder browser pops up and any audio source file can be selected here.
After adding any audio source, as in video source, all source information and parameters can be examined. Also these information types and values change according to selected audio source. As an example The "Source Parameter" tab at the image is for "File Source".

Unlike other sources, Decklink Cards have two options while adding them as an encoder. Direct Show (DS) is one of them which is same with other cards. Low Level (LL) is other option and this is a bit different from other cards. When a video source is added as an encoder with LL option, audio will be in this video source too , so an audio source seperately can not be added.
As it seen at the picture , audio and video are both seen as one source. Capture audio should be checked if audio of the source is desired to be ingested also. Audio input should be selected as “Embedded” if the source is connected as SDI. Channel amount is two and can be changed if source channel amount is different.

An encoder cannot be removed while source is encoding. There are several ways to remove an encoder.
- From Toolbar Menu
- From the Project Menu : “Remove All Encoders” can be used too but this will remove not only the encoder that focused on but also other encoders as well. Obviously, it removes all the encoders.
- From the Encoder Menu:
- From Right Click Menu :
- From Hotkey : Another easy way to add a new encoder is using hotkey CTRL+SHIFT+F2.

There are meanings of symbol at the "Encoders " view at the Left Panel after adding sources and profiles.
A. Capture Mode
B. Source video size and frame rate
C. Source audio channels and Sample rate
D. Source buffer
E. Capture time (duration)
F. Profile 1
G. Profile 2
H. Profile 3
I. Samples buffer, sample count for profiles. This is the sample count on queue waiting for encoding. If this number increases then it means the system is not adequate for encoding in this profile.
J. Capture time (duration) of profiles.
K. [O] icon: Burned-in video overlay enabled on current profile
