You can also configure each field yourself. Click Show advanced for more details. Depending on the selected mode (FTP/ Kaltura / Presentations2Go) you will see a different interface.



Controller Listen IP Address

The IP address used to communicate with the video server. In case you have 2 network ports, select the correct network to improve live and publish performance.

Remote Control User Name

These settings are only used to remote control the application using the webinterface or API (e.g. AMX / CRESTON integration).

Remote Control Password

These settings are only used to remote control the application using the webinterface or API (e.g. AMX / CRESTON integration).


Hardware Acceleration (Presentations2Go live)

GPU rendering will reduce the CPU load. 3th generation or higher Intel processors can use QuickSync GPU for video rendering. If you have a 7xx or higher Nvidia card you can also use CUDA GPU video rendering. Make sure you install official Nvidia drivers. Windows default nVidia driver is too old.


Check the availability of nVidia CUDA / Quick Sync / AMD Radeon by selecting a mode. The check is automatically done.


Days to keep past schedules

Past schedules are only removed from the iStream Studio list after this time period. Default value is 90 days.


Schedule Sync Mode (Kaltura/Presentations2Go)

This feature enables you to setup a master - slave setting.


  • Two ways
  • Server to Controller


Default two way sync will be selected. With the Server to Controller setting the Server will become the master and Controller the slave.


iStream Studio Features key

The features key is automatically updated during application start when you are on-line. The features key unlocks the software based on the features you purchased.

Operation Mode

There are two operation modes

  1. Standard; lecture capture / event mode
  2. Personal Capture.; In Personal Capture mode theiStream Studio will minimize when you start a recording. Also you can setup a countdown delay.


 

Communication Buffer Size

This parameter influences the upload speed during publication. The default value is 5120KB.

When you have limited bandwidth and experience the upload is failing or keeps retrying you can decrease this value to e.g. 1024, 512 or even 256.

If you have a stable and excellent bandwidth you can double the value to 10240



Show Live Stream Log Window (Presentations2Go)

If you have trouble with live streaming you can monitor the stream log. A separate window will appear as soon as you start live streaming.


Warn before exit

Check this if you want to get a warning pop-up before the application closes. Keep in mind closing the application will also close vMix.

Disable Canvas

When you start recording with a output source which contains a multi-view with 2 sources (like the side-by-side source), the metadata will be setup to generate slides based on the slide source value and canvas coordinates. This will result in index slides. However, during manual recordings of special events you might want to disable this feature and be free to change output sources as you like without concerning about slide detection an player consequences.


Delete after publish

This feature will delete the mp4 file after publishing, but will keep the folder with log,  metadata and thumbnail on the local disk.


This way you can still monitor history in the publish window. Publish and deleted files can be recognized with the icon below.



Pause keeps original recording duration

Default enabled. When you disable this feature the recording duration will increase while using pause. E.g. when you start with a 100 minute duration and pause for 10 minutes the total recording time would become 110 minutes. Since this would cause issues with automatic scheduled recordings, it is advised to keep this feature turned on.

Automatic stop external with live (Presentations2Go)

When you stream live, external is automatically turned on. This option will also disable external when you stop live streaming.



Auto Upgrade

When you start theiStream Studio the software will check on-line for new releases and pop-up a notification window when a new release is found.

Automatic Deletion Rule

To prevent full disks, you can enable automatic cleanup of old recordings.


vMix User Name &  vMix Password

In case you want to protect the vMix API, you need to allow iStream Studio to call the vMix APIs.



Split Video Tracks

When you enable this the recording will not be made by vMix, but performed by iStream studio.

Based on the selected layout, the output screen will be split up and recorded in separated video tracks.


Recording hardware acceleration

Since iStream is now recording instead of vMix, you can select hardware acceleration. Once you select an option, it will first test if this option is available.


Recording Quality

The recording quality (per individual track) can be set.

  • low (2Mbps)
  • medium (4Mbps)
  • High (8Mbps)


NOTE: Since this applies per track, low would be sufficient for Full HD projects.

Layout

iStream installs a list of vmix profiles you to use (C:\Program Files\iStream Studio). Match the layout with the profile you have setup in vMix to split the tracks accordingly.

Slide source

Slide detection is performed on the selected part of the output you select here. In the main interface you will see a hint (orange). Slide detection is done after recording, it will use the last known value and be the some for the complete recording.



NOTE: Use alt+click to select another area.

Minimum Slide Interval

Slide detection can create a lot of slides, especially when video is presented in the slide detection area. This can increase the loading time of the Kaltura player. Therefore you can limit the slide interval by setting a timer interval. For PowerPoint presentations a 5 or 10 second interval would good to start with.
