Render Method Controls the method used by the player to process and display the video.

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

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

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 audio

quality, 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
