Video Source

  • Set Framerate is to change the number of frames per second. Higher rates will resut in smoother videos but will consume more memory and increase the CPU load. If this field is disabled, then it's necessary to set the framerate in the ip camera's web interface.
  • Effective Framerate is the true rate of frames reaching ContaCam, this value may differ from the above one in many circumstances: for example some USB cameras only support framerates at fixed steps or in the case of network cameras this value can oscillate if using a wireless connection or if the network or the computer are overloaded.
  • Data Rate indicates the amount of camera video data in kilobytes per second. If two values are shown then the first one is the compressed data rate coming from the camera and the second one shows the data rate for the uncompressed frames.
  • Process Frame Time shows the necessary milliseconds to process a frame. On faster computers this value is smaller.
  • Dropped frames should usually be 0. If this value increases over time then the USB bandwidth has been exhausted, try to plug your USB camera directly into the computer and not through a hub and try also to lower the camera framerate and/or resolution.
  • De-Interlace has only to be enabled for interlaced sources from analog capture cards which show the typical interlacing artifacts on moving objects.
  • Rotate 180° can be enabled when the camera is placed upside down.
  • General Settings is enabled for capture cards and USB/DV cameras. It displays the camera specific general settings dialog.
  • Video Size & Format can be called to change the wanted video size, pixel format or compression. If this button is disabled, then it's necessary to set the video size in the ip camera's web interface.
  • TV Tuner opens the analog TV tuner dialog.
  • Video Input Select is used to choose the input of an analog video capture device.

Audio Source

  • Enable audio recording together with video.
  • Listen to hear the audio live.
  • Source can be pressed to select the sound card or a USB camera audio source.
  • Mixer button opens the Windows Mixer to regulate the levels of your audio source.

Minimum Font Size for Frame Time

The frame time/date font sizes increase proportionally to the video resolution. This value sets the font size for the smallest video resolutions.

Autostart Camera

Checking this box will start the current camera automatically when starting ContaCam.

Video Compression

Quality will impact the video appearance of the saved files. Higher qualities result in bigger files with better visual quality.

Keyframe each sets the keyframes rate, for smooth video player seeking leave it at the default of a keyframe each 30 frames. To get smaller video files at the same quality it's possible to increase this value to 120 for example.

Continuous Recording

Continuous recording settings apply to manually started recordings (through Capture - Record or through the red dot toolbar button) or to recordings started by the below described schedulers. The settings listed in this section will NOT impact the motion detection recordings.

  • Start a new file each given amount of time is used to split the continuous recodings into multiple files.
  • Open file when done will start your favorite video player when done with the continuous recording.
  • Once Scheduler is used to setup a one time scheduler.
    Attention: scheduler will not start the recording if ContaCam is not running!
  • Daily Scheduler is used to record on a daily schedule.
    Attention: scheduler will not start the recording if ContaCam is not running!
