- Video Calibration
- This option opens the window in which you can calibrate your video playback. It offers the ability to adjust
- The overscan of the video - How close to the edges of the screen that the image is displayed
- The positition where subtitles are displayed
- The position of the on screen display
- The pixel ratio - allows you calibrate the aspect ratio at which videos are played back
- Configure Audio Hardware
- Opens the Audio Configuration Menu
- Render Method
- Controls the method used by the player to process and display the video, (which is called rendering). See Here for more information on the different options.
- Adjust refresh rate
- Activate to automatically set the refresh rate which is best matched with the video that is playing
- Allowed error in aspect ratio (%)
- Allow video player to try to fit video to screen by ignoring aspect ratio by a certain amount
- High quality upscaling (GL only)
- Enables video upscaling to resize the source video frames to the size of the screen (XBMC's resolution). Note: Overrides the OSD hardware setting
- Upscaling method (GL only) [Bicubic, Lanczos, Sinc, VDPAU (GL & Linux with VDPAU capable Nvidia GPU only)]
- These methods use FFMPEG's software scaler (swscale). The differences between them is the algorithm used and the number of "taps" performed for calculating the final pixel's color. Sinc is generally the highest quality but also the most time consuming, followed by Lanczos and then Bicubic, however, this can be subjective. Note that all these methods are software methods, they are not hardware accelerated, so enabling them can result in frame drops and out of sync audio depending on your CPU, resolution etc.
- VDPAU HQ Upscaling level (GL & Linux with VDPAU capable Nvidia GPU only)
- Requires NVIDIA's linux driver v190.32 or later and VDPAU 'Feature set C' capable GPU (see driver README)
- VDPAU Studio level colour conversion (GL & Linux with VDPAU capable Nvidia GPU only)
- Enables studio level color correction. Corrects errors occurring from conversion between Y'CbCr and RGB. Useful if your TV can't handle PC level color ranges
- Forced DVD Player Region
- Forces a region for DVD playback.
- Attempt to skip introduction before DVD menu
- Attempts to skip 'unskippable' introductions before DVD menu
- Enable edit and decision lists
- Enables edit and decision lists (see EDL (commercial_skipping) and SceneMarker support)
- Sync playback to display
- This setting enables syncing the video to the refresh rate of the monitor.
- A/V sync method [Audio Clock, Video Clock(resample audio) or Video Clock(Drop/Dupe Audio)]
- Audio has to stay in sync, this can either be done by resampling, skipping/duplicating packets, or adjusting the clock if it gets out of sync too far. Resampling has the advantage that the speed of the video can be changed considerably, so 24 fps can be sped up to 25 fps to play at PAL speed. The disadvantage of resampling is that it doesn't work with passthrough, and there is a slight loss of audio quality. Skipping/duplicating audiopackets has no loss of audio quality, but the speed of the video can only be changed a little to avoid doing a skip/duplication too often, most of the time it's inaudible, but it can produce a very audible click. Adjusting the clock has the best audioquality, but some extra video jitter can occur, also the speed of the video can't change much, as the audio will sync the clock more often the more the speed of the video is changed.
- Maximum resample amount (%)
- The maximum percentage the speed of the video can be changed to fit the refreshrate, the default is 5% to allow cinema to PAL speedup (24 to 25 fps, 4%), this is only available when resampling (a small speed change will still happen without resampling).
- Resample quality
- Quality of the resampler, goes from low to really high, the default is medium which should be fine for anyone. The higher the quality of the resampler, the more cpu it will use. You can look at the resampler types at libsamplerate
