Again thank you for this invaluable help! About Waveform Monitors and Vectorscopes. Perhaps I should repeat the test with everything at 15 fps. TMPGEnc and other mpeg encoders have a setting to adjust for this. I ran the. Y This format is a packed bit representation that includes 2 bits of alpha. There are two common variants of sampling. Page 1 of 2 1 2 Last Jump to page: Results 1 to 30 of The bit representations described here use little-endian WORD values for each channel. Attached Files YUY2-small sample-redone.
YUY2 is the preferred pixel format for Microsoft DirectX Video Acceleration ( DirectX VA). It is expected to be an intermediate-term. This topic describes the and bit YUV formats that are These two formats are the preferred planar pixel formats for They are expected to be an intermediate-term requirement for DirectX Video Acceleration (DXVA) accelerators that support bit or bit video.
YUY2,Packed, 8. The hardware acceleration is on full. The YUY2 sample you provided is uncompressed RGB24, not YUY2 (the BY8.
MY WORLD About YUV Video
It gives you a half sized image and treats the RGB sub-pixels as coincident rather than spacially offset.
Latest tool updates. In signal processing terms, the vertical upconversion should ideally include a phase shift compensation to account for the half-pixel vertical offset relative to the output sampling grid between the locations of the sample lines and the location of every other sample line.
Surface Definitions? It was an interesting exercise for me too. Z is the black-level variable.

|These are the exact formulas without approximation.
This array is followed immediately by all of the V Cr samples. As a color's pure saturated intensity increases, it moves out toward the edge of the scope. For virtualdub, there is clrtools by Trevlac that can show a vectorscope.

There is no source code with that plugin, but the author refers to using the method by Menon, Andriani et al, "Demosaicing with directional filtering and a posteriori decision".
It is characterized by different values for these two constants:. YV12 encodes the grayscale information at the source's resolution x in your case and the colors information at half resolution x
for DirectX VA Accelerators that support video. UYVY. This format is the. supports video encode acceleration via the Intel® Media Software. Development.
YUY2 input and automatically converts to the supported pixel format (NV12).
It is expected to be an intermediate-term requirement for DirectX VA accelerators supporting video. I think there will be more than a few planetary astrophotographers interested in this Debayering outcome using AviSynth.
Is the Debayer function built into AviSynthor is it a filter I need to download from somewhere? Would you happen to know the method this AviSynth Debayering script uses to Debayer?
YUY2 vs RGB24 vs Y VideoHelp Forum
I hope you don't mind if I pass along this solution.
If the video display mode is set to Preview and preview acceleration is enabled, the RGB formats can be cropped to pixel accuracy; YUY2/UYVY can only be.
YUY2 is the preferred pixel format for Microsoft DirectX® Video Acceleration (DirectX VA). It is expected to be an intermediate-term.
If you start with video that uses the sampling grid defined in H. Optical Quantum BD-R.
The x,y coordinates of R, G, and B are 0. Everything that follows in this document is derived from these formulas.

The starting address of the U and V planes are calculated as follows:. I am positive this one is "direct stream copy. Summarized the hue is the color flavor, the saturation the dominance of the hue in the color and the intensity is the black-white portion.

|Pixels are organized into groups of macropixels, whose layout depends on the format.
You can also switch the order of the two upconversion processes, as the order of operation does not really matter to the visual quality of the result. In this article. The charts and graphs are covered in the tools for adjusting subsection below. The problem with this is that if you don't deal with this correctly, you will get washed out looking video.
