Video Settings
First of all, all profile settings are not identical. They are different due to their formats however they may have similar settings.
Quality Settings
Firstly, adjust your quality bar before making any changes at Video Settings. If quality bar moved after any manually changing, these changes made manually , probably get reset or change differently.
...
Settings
In settings window, there are three tabs of setting which are Basic settings, Advanced settings and Miscellaneous. Detailed setting of a profile can be adjusted from this window. It should be considered carefully that not all adjustments are acceptable therefore user should have some knowledge about these settings. Settings window is shown below for Basic , Advanced and Miscellaneous Settings. You can adjust Video Format (resolution,frame rate, etc. ) Bitrate ( bitrate mode, target bitrate , etc. ) , Profile (Main, 4:2:2, High , Simple) , Level(Main , High , Low , High 1440), GOP Stracture , Picture Coding Style , Motion Estimation , Quantization Matrices, Input Format and Stream Stracture settings from this window.
...
Another important thing about this window, do not go back to profiles window to edit anything before closing settings window.
2 Pass
“2 pass” is an option which helps to transcode files with better qualities. If “2 pass” option is checked, when transcoding started application does not start to transcode file immediately.
...
But obviously there are some conditions to use “2 pass” successfully. First of all, it can only be used while transcoding. This means while encoding online source, this option is not applicable. Another thing which should not be forgotten is that while encoding a file with this option you can manually stop or split encoding , its workflow is very different from other encodings. Still, you can enter in-out point to source file.
Deinterlace Source
Technically, this option deinterlaces an interlaced source before encoding. Deinterlacing may be required to display an interlaced video on a progressive scan display.
Muxer Settings
If you click Muxer tab this window appears which is shown below. Any muxer from the list can be selected here and some muxers have their own settings which users can adjust according to their needs.
Muxer Types are seen at the picture on the left.

Audio Process
Audio process section is shown below .This is where user can adjust audio channels and streams.
There are two selection for audio process :
-Use Audio Mixer : If profile is a one stream audio, “Use Audio Mixer” is the option that should be used. If you choose this section you can adjust Audio Mixer Settings. By default, ingest automatically assigns source channel to same destination source channel. As long as source and target audio channel count matches, this default assigning fits so every channel of source and target is used. If source and target audio channel count doesn’t match, ingest only assigns the source channel which has the same target source channel ,leaves rest as empty.
-Use Channel to Stream : There is another option as “Channel to Stream” which should be used when target stream is more than one. When this is selected, a new button appears as “channel to stream” and it pops up a new window for its settings. In this window, stream count can be adjusted. Ingest automatically assign only first stream same as audio mixer. All other streams start as empty. They should be assigned manually.
