Setup Video Properly: To enjoy video in an optimal way, please read here:

The AlbumPlayer doesn't have its own Video codecs. Here are some recommendations to have proper video playback.

- Install K-Lite codec pack: http://www.free-codecs.com/download/k_lite_codec_pack.htm
- Disable Windows Media Foundation from the Codec Tweak Tool (k-lite codec pack)

Especially disabling WMF is important to get a fluent playback . The WMF can cause a lot of stuttering.

See screenshot of advised tweaks here:

Important Note : The video playback has some limitations. The audio is directly playing back over the audio device. This does mean that the equalizer or any other DSP functions are bypassed. Depending on the video renderer selected in theVideo  page of the preferences it plays back over the default audio device or the same audio device as for the regular audio playback selected in the Audio  page of the preferences. ASIO is not supported. Also it is not possible to automatically calculate any Replay Gain values for Normalized audio playback. Still it is possible to enter negative Replay Gain values yourself for the each video track, because this level is then used to lower the volume level of the video. Despite the limitations, the use of video can still bring a lot of fun.
