JRVR Video Renderer
jmone:
Any plans for IVTC? I really hate NTSC bodges, but was looking at one of Murray's problematic movies (Oklahoma!) and the processing of this 60i BD Encode (remuxed to MKV) is tough to do without massive frame drops. I may get him to post a link to a 10min sample if you are interested. The other option is to post process the video stream.
The odd thing in this testing is deinterlacing seems very expensive (YADIF worst, then D3D) but the OSD stats seems weird at times. I can get constant dropped frames when MAX render time is reported as around 10ms when using D3D, so I'm not sure the stats takes the HW Deinterlacing into account, and at other times the MAX render times can jump to over 30+ms and not drop frames.
The next odd thing is when in 59.94hz mode, the reported VSync wanders all over the place, which I don't think helps. I don't see this on 23.976 or 50hz.

No plans for IVTC at this point.

No probs - more than one way to skin a cat.

I'm adding black bar and aspect ratio options to JRVR currently, and I wanted to get some feedback if this covers everything sensible for usual setups.
Basically this is what I'm thinking right now, on a per-output basis in JRVR.
- Enable Black Bar Cropping
- Crop to [Automatic] (using the metadata), and [a list of common aspect ratios] (similar to whats available today in the context menu)
- Aspect Ratio Mode: Preserve, Stretch, Crop. Existing options as a per-output default. (moved from Video -> Aspect Ratio mode into per-output settings)
- Aspect Ratio adjustment, eg. a factor to adjust the aspect ratio by. Might have some presets and an input for a scale factor. This would be used for anamorphic lenses (or older screens with non-square pixels).
(this option was previously available in Video -> Aspect Ratio correction, this is moving it and making it per-output when using JRVR)
Advanced:
- Vertical Image Shift, Shift image to the top or bottom, rather then centered.
These are essentially all existing settings, streamlined into per-output settings in JRVR, and of course making use of automatic black bar cropping based on the metadata we're gathering now.

It sounds good to me
