In this tutorial i will show you how to play movies filmed in 23.976 FPS (Frame Per Second) flawlessly, without stutter and jitter.
The problem: When you play on your TV a movie file that was shot with 23,976 FPS you will see from time to time, especially when the camera is panning from side to side, a small “stutter” in the video, the image is not moving in a fluent way, it looks jerky.
Why does it happen: In a nutshell, this happens because films are usually filmed in cameras that record 23.976 frames per second. your TV probably support a refresh rate of 24 HZ, the refresh rate and frame rate should be equal, if they are not, this will cause a stutter in the video output.
Solving the problem:
- Install XBMC / Kodi
- Connect your PC to your TV using an HDMI cable
- In your Graphic card driver change the refresh rate to 23 HZ or 24 HZ
Note: 23 or 24 HZ will be available only if your TV support it, most modern TV’s do
- Since XBMC / Kodi version 13 you need to set “Settings level” to Expert in order to see all options
- Go to Settings > Video > Playback
- Choose Adjust display refresh rate to match video = Always
- Choose Sync playback to display
- in A/V sync method choose Video clock (resample audio). Not available in Kodi 15.x
- Using XBMC / Kodi play any 23.976 content
- Click the letter ‘o’ in your keyboard (not zero). this will show you video statistics. you will need to focus on 3 properties mainly
fr:23.976 – this means that the file is filmed using 23.976 frames per second refresh:60 – means that your TV screen refresh rate is 60, this is on my laptop so it shows 60. when you change the refresh rate in your GPU driver to 24 it should show 24 error: 33% – this is where to check if there is jitter or dropped frames if everything is working OK you should see error=0%. watch the statistics for about 1 minute, if it stays on zero for a minute, problem solved. if the error value jumps from 0% to a different value during this minute, this means there are dropped frames and something is wrong.
Troubleshooting: There are movie files that are encoded in Variable frame rate and not Constant frame rate. XBMC / Kodi does not know how to handle this. this means that if the movie is in Variable frame rate, the fix above will not help. there is a defect in XBMC / Kodi site here. i do not know when this issue will be fixed.
