I noticed that many decoders offer the choice to convert the color space from the given one to RGB for the output in their preferences.
My config:
- OS: Windows XP SP3
- Player environment: CCCP 2009-09-09
- Graphics card: NVIDIA 7900GT
- Decoder: CoreAVC 2.0
- Input levels: Auto detect
- Output levels: PC (0-255)
- Deinterlacing: None (Weave)
- Input Colorspace: Auto detect
- Deblocking: Standard
- The rest: Only "Preferred decoder" and "Tray icon" (I don't have a CUDA capable card) checked, all other unchecked
- Renderer: VMR9 (renderless)
- Surface: 3D surfaces (recommended)
- Resizer: Bicubic A=-0.75 (PS 2.0) [shouldn't matter here]
- D3D fullscreen: off
- VMR9 mixer mode: on
- Alternative VSync: off
- YUV mixing: off
After reading Microsoft's page on the YUV Mixing Mode I think turning YUV mixing on will only result in decreased quality, so I won't post screenshots for it turned on here.
Info for the interested users: The "Same as"-comments remain the same after turning it on but all screenshots are slightly different compared to the versions with YUV mixing off; furthermore the RGB results are quite different, with the option on, they are much brighter.
I have tried most of the available color spaces separately on the file [UTW-THORA] Evangelion 2.22 - You Can (Not) Advance [BD][1080p,x264,DTS-ES][8B521921].mkv at the first frame of the scene @ 00:08.44 (frame 12567).
After setting the output color space in CoreAVC's settings, I restarted MPC HC and took the according screenshot.
Here are the results:
Color space | Note |
| |
| Similar to the one before |
| Similar to the one before |
| Similar to the one before |
UYVY | Exactly the same as with YUY2 |
| Quite a difference compared to previous ones; stronger colors |
RGB24 | Exactly the same as with RGB32 |
By calculating the CRC32 values of the YUY2/UYVY and RGB32/RGB24 results, I have seen they are exactly the same.
Which format shall I take when
- taking screenshots?
- watching the show on a usual RGB monitor?
Does the BakaBT staff prefer any combination of settings?
Naively I would guess that RGB(24+) is the appropriate choice because that's what my monitor is displaying. Am I right?
Furthermore the question arises whether one should choose PC (0-255) or TV (16-235).
Thank you very much for your help.
