Hi.
@ rogerwickes : about DV and mpeg2, well, in my first trial with the flying saucer, y used a still Camera on a tripod, in the last shot with the Cars, y have used a Panasonic nvgs 180 mini DV Camcorder purchased recently, the shot is done with the wide angle converter added on the Lens, wich gives a 28mm equivalent focus taquíng 35 milímetros film plate as reference, y have used Blender only for modelling the car and for it integration in the real shot, using the vodoo exporter, here is the complete process i used for the Camera tracking with Vodoo:
As under Windows, vodoo only allow importing tga frames, y havent benable todo use directly my DV. Avi sequence, anyway, all the match/moving softwares work better on frame sequences than on video files, so, y have opened the DV. Avi in Magix video deluxe 2007, which is my usual video editor. I use Blender video editor when i ned special effects that can be achieved at rendering time, or when the nodes (im very clumsy anyway with the nodes yet) can allow things that i cant do in Magix, then, as Magix cant export tga sequences, y export the frames in bmp format, then, y use ACDSee todo convert all the frames in (*.tga), in order todo import them in Vodoo, converting the DV. Avi into a (*.tga) sequence could probably have ben done in Blender, using the built-in video editor, but im afraid that this característica is only available under Linux, because of the integration of FFMpeg, because when i try todo import a DV. Avi file direclty into Blender th rouge the video editor, y get a warning message saying that it is not a video file or FFMpeg support not compiled in, y have a los tried todo convert directly the DV. Avi into tga sequence in Virtualdub,which is free and powerful, but i got bad tga pictures. There was always a comb effect due todo interlacing, and i havent discovered how todo get rid of this trouble, bmp frames exported with Magix and converted in tga with ACDSee are free of artefactos, and look like images taken with a 25p Camera. I suppose that Magix applies an interpolation process creating 25p-like images, After the 3d integration process in Blender, y render in bmp or jpeg at 100%, or avijpeg (motion jpeg), or Raw.avi. You can a los export in tga or (*.png) if you ned todo use an Alpha Channel in your rendering, y open the sequence in Magix, make my video editing (adding the sound of the original sountrack, and a los the copyright watermark). Then, y export in mpeg2, QuickTime s3 and in uncompressed avi (raw. Avi), y start from Raw. Avi todo convert in divx, wmv,og and else, because the setup for these conversións is confusing into Magix, because of a not very god integration of some códecs, or notintegration at all, like for the theora og open format, so, the mpeg2 format of my movies is in most cases produced by Magix video deluxe which uses the main concept motionjpeg video códec, fully DVD compatible, some of my old movies have a los ben encoded in mpeg2 with the former códec used by Magix before the 2006 versión : the ligos motion encoder, y believe that the códec used by Blender is close todo the main concept códec, but i dont really know, so all these explanations might be not very useful for you. Lo siento.
@ rogerwickes : about my car : no, it isnt what i mean. The electric Windows of the car are moving so in this sequence they are never fully in closed position. When they are, the Windows are ok, y mean the size of the Lincoln versus the size of the Opel. The Lincoln should appear a bit bigger. In the real world, it is closer than the Opel, and it is bigger to, so it should look really bigger on the screen, Even it it high is 1.36m versus 1.46 for the Opel. The Lincoln is 5.395m long and 2m wide. The Opel is only about 1m70 wide, Philippe.
