**Short description of error**
The patch for T47724 now causes the video chroma planes to be scaled differently to the Y channel.
Colours look aligned on the left, but get progressively shifted towards the right. Especially noticeable on the green bars (bottom of the three images):
{F289531}
^ This happens even if the src video and project dimensions are divisible by 16, eg 720x480.
*As a side issue, the CbCr channels are now upscaled with interpolation instead of nearest neighbour. Interpolation obviously looks more pleasing for previewing (and might make green-screen keying easier), but might not be wanted for simple 'pass through' work like editing/grading as it will end up softening the image a bit.
**Exact steps for others to reproduce the error**
- open F289048 .blend
- load {F289533}
- video is 854x480, h.264, 25fps, 4:2:0 (encoded with ffmpeg 2.8.4)
The test video can be created from scratch using:{F289535}
with:
ffmpeg -loop 1 -i 854x480_vertical_rgb_grid2.png -pix_fmt yuv420p -crf 20 -t 4 854x480_vertical_rgb_grid2.mp4
