![]() Or, to be more precise, at least 7 or 8 atm (atmospheres), with 1 atm being normal atmospheric pressure. That said, an explosive decompression can happen in real life if you get a really high-pressure gradient - from far above-normal pressure down to atmospheric pressure, say. As one of the great classics of Hollywood Science, the belief in explosive decompression is so widespread that audiences are more outraged when it doesn't happen (see The Coconut Effect and Reality Is Unrealistic). Good luck getting all of this across to most audiences, though. It is far less likely if the decompression occurs slower than about half a second, which is quite common in sci-fi. Pulmonary barotrauma (lung rupture) is possible, but not guaranteed. Incidentally, holding your breath would be worse than useless the difference in pressure would cause a serious and fatal embolism even from the smallest amount of air in the lungs resulting in death even if someone manages to rescue you. But, you never quite go boom: remember, technically speaking, your blood is not in a vacuum: it's in you, so swelling and boiling blood only occurs toward your squishiest, outermost layer of capillaries. When you step outside, you've got about 15 seconds before you pass out from anoxia note the medical term for oxygen deficiency, a couple of minutes at best until you die from the same, and all sorts of nasty decompression injuries in between (exposed areas swelling up, body fluids boiling off your surfaces). As unfriendly as the vacuum of space is, the body's made of stern enough stuff to stay in one piece. Woe betide anyone foolish enough to step into it unprotected (or unfortunate enough to get Thrown Out the Airlock): they'll pop like a turkey with a grenade stuffed inside. In most fiction, outer space is not friendly. These codecs are very helpful for those using older machines and older versions of codecs and media players.- Space Quest III: The Pirates of Pestulon death message Other 64 Bit Codecs for I420/IYUV/YV12 are no longer replaced by the Helix Codecs and can co- exist now with the Helix Codecs. The new INF- File restores the native 32 Bit Windows Codecs if the Helix Codecs are uninstalled and removed from the System. (Conforms now to the Microsoft White Paper for YUV Formats in Windows) Solved Problems with DirectX, Direct Draw, Active Movie, Direct2D, Direct3D and OpenGL FourCC Mapping from I420 to IYUV. Solved Problems with the FourCC Codec install Order in the Registry. Solved minor Problems with HonesTech HDV Encoder, MainConcept, Craaft Cinema, Cinegy, Microsoft and Pegasus encoders. Fixed Problems with Osprey/ATI/Matrox/Intel/Aurora/DVS and other popular Videoboards. Fixed Problems with Empia/Afa/SynTek and other Capture Drivers. Fixed decoding Arksoft IYUV and ATI YV12 Videos (32/64 Bit) with the Helix Codecs for encoding and decoding. Fixed decoding Drastic YCbCr I420/IYUV/YV12 Videos (32 Bit) with the Helix Codecs and works both ways now for encoding and decoding. Fixed decoding Intel I420/IYUV Videos (32/64 Bit) with the Helix Codecs and works both ways now for encoding and decoding. ![]() The IYUV Codec now reports itself as "Helix IYUV 420 Codec" instead of "Helix IYUV YUV Codec". The IYUV Codec stays now in 12 Bit and does not upscale to YUY2 anymore to other 12 Bit Codecs. Modified I420 Codec for IYUV Colorspace (same as I420) and added the "iyuvvfw.dll" Codec for both Versions. The codec responsible for handling each format is selected automatically. Unlike XviD and MS H.263, the Helix YUV Codecs can convert both to and from I420 and YV12. On the other hand, the Helix YUV Codecs can handle multiples of 4. The aim of the Helix YUV Codecs was to provide a better alternative to MS H.263, which couldn’t handle dimension multiple of 15 or exceeding 352 x 288. VfW codecs are necessary for playing and editing in VirtualDub and other similar applications. With the Helix YUV Codecs you can obtain fast color conversions to the most popular RGB formats, YUV2 and I420 and YV12 when requested.Ī limitation for these tools is that width has to be a multiple of 4, and height needs to be a multiple of 2. The difference is that i420vfw.dll encodes to I420, while yv12vfw.dll encodes to YV12. They are almost identical, as they accept common input formats and provide lossless compression. I420 is YV12 with the chroma planes swapped.īoth tools decode I420 and YV12. The components of the Helix YUV Codecs pack are an I420 VFW Compressor/Decompressor and an YV12 VFW Compressor/Decompressor. Other actions performed by this codec are handling the output of AviSynth scripts and compressing video files to these formats.
