1.10.3 and 1.10.4 (test 12) both crash when I try to use RemoveGrain from VapourSynth Script.
Here's the report: http://pastebin.com/YRZbrDBg
(also VDub detects my Win8 as Win7  ) |

Removegrain crashed and virtualdubs letting you know
For some strange reason that bit of code is trying to talk to IOports??
Offhand I'd say something went wrong a long time before that, and now it's executing random bytes of memory
Either way, it's a RemoveGrain / VapourSynth problem

And my version åõå VirtualDub110413.rar in Russian and English, together with file VirtualDub.vdi. At batch operation has noticed an error, when this file from other set). |

Incorrect links to test13 in the first post of topics. |

1. open a video file
2. Video->Color Depth...->Ouput format to compressor/display->4:2:0 YCbCr (NV12)
3. Video->Compression...->Uncompressed RGB/YCbCr.
4. save the video file
Properties of the resulting video:
BITMAPINFOHEADER:
biSize: 40
biWidth: 720
biHeight: 576
biPlanes: 1
biBitCount: 16
biCompression: NV12
biSizeImage: 622080
biXPelsPerMeter: 0
biYPelsPerMeter: 0
biClrUsed: 0
biClrImportant: 0
Is this a bug? |

meowmeow believes its' not. 420 compression leaves average 12 bits (48/4=12) per 2x2 (or 4x1) pixel block. Single pixel still gets its 16 bit color from average values. |

Ha. For example, look YV12.

That's exactly 12 bits per pixel (622080*8/720/576=12). Which cannot be for packed images. Unpack that data to see. Meowmeow confused. |

YV12 & NV12 are 12 bits per pixel, but as meowmeow is saying (I think!) the YCbCr uncompressed format uses 16 bits per pixel for efficient processing. |

This is nonsense.
NV12, YV12 and I420 uses 12 bits per pixel.
YVY2, UYVY, YV16 and HDYC uses 16 bits per pixel.
Can save in NV12 and YV12 and compare the size of the files. Then compare with YVY2.
VirtualDub creates the wrong properties for NV12. |

How NV12 works (not exact theory)
Y1+Y2+Y3+Y4+Cb+Cr = 6*8 = 48.
48/4 = 12 bpp average.
| CODE | Y1Cb + Y2Cb
Y3Cr + Y4Cr |
Displaying YCb/Cr: Y+C=8+8 = 16 bpp interleaved.
While NV12 is "clearly" 16 bpp, YV12 works like... matrices instead of interleaving. Safe to say, YV12 is 12 bpp
And H.264 uses 0.05 bpp |

Ignoring the BITMAPINFOHEADER, MediaInfo reports the file like so: | CODE | Video
ID : 0
Format : YUV
Codec ID : NV12
Codec ID/Info : 8-bit Y plane followed by an interleaved U/V plane with 2x2 subsampling
Duration : 1s 668ms
Bit rate : 331 Mbps
Width : 1 280 pixels
Height : 720 pixels
Display aspect ratio : 16:9
Frame rate : 29.970 fps
Color space : YUV
Compression mode : Lossless
Bits/(Pixel*Frame) : 12.000
Stream size : 65.9 MiB (100%)
|
...maybe MediaInfo is wrong too... |

version 1.10.4/35488 test 13.
- remove all plugins and filters.
- Windows XP SP3
- Open a video
- Select compression=(uncompressed RGB/YCbCr)
- Crash (see crashinfo.txt)
- version 1.10.3/35390 is OK
crashinfo.txt (dropbox)
EDIT - works OK if default settings are NOT loaded with the "/s" command line switch, but are loaded manually instead.
This happens even with the most basic settings possible:
test_nofilters,vid=blank,aud=pcm.vcf (dropbox)
EDIT - I guess I am using this feature in a manner not intended (it's supposed to be for encoding from the command line), so I can't complain if it is 99% functional when used for loading a 'profile.'

Confirmed NV12 bpp is incorrect -- fixed in 1.10.4 final.
Will look into the .vcf crash.
Update: This scenario should work, and I can't reproduce the crash. Does this happen if you use a test video from Tools > Create Test Video instead of loading one from a file?
