Frage von Balrock:
Hi folks!
I've ne Ziehmlich technical question, because I have a few effects prior to program themselves (tailor-made for my SonyVX 1000 with 16:9 anamorphic).
Pal DV recording with 4:2:0: brightness information is stored for each pixel, wärend Farbinfos only for pixels in every second row will be saved ... right??
Now the picture but interlaced! Does this mean then that the first field saved when all pixels with color information and brightness information in the second field only and nothing else ?!?!?!
Or is it "... in every other line ..." only within a video field, so I in a de-interlaced picture will always have two rows and two rows Farbinfo did not??
Another thing: Is this color information, always the average for the (two?) Associated pixel or how this figure come about?
I hope there is some tech freaks Euch'n under which I can explain things ;-)
MfG
Balrock

For which program you want to program?
I hope so much for Avisynth and VirtualDub!
If you find that Avisynth has the relevant information in the reference - Keyword YUV color spaces. And all around the Einleserei, Dekodiererei, Abspeicherei, so you need not bother about. Just to the g * ilen Effect or filter pur ;-)
Good luck

> Fat Stefan Hello Stefan,
I nen Mac and I thought machs equally correct: C + + with QT Import and Export and a cache in RAM (uncompressed), where the images are then processed synonymous.
No idea whether that simple () goes, but the effects, which I imagine is with the pseudo-programming languages such as FinalCut, ... Action Script not in it - I'll take time to (?).

I have the issue only twice reingestell because I did not know where to fit them better.
And besides, I les synonymous only the contributions in certain parts of the Forum (which interest me stop!) And the others probably do as synonymous - so it's not as stupid a question to post 2 times (not 78 times does not matter ;-) , then find the answers from different directions!
To expand, because of the horizon, and so ;-)

Antwort von Stefan:
Mit'm Mäc ;-) I know it not from me, I do not know. Sorry.
Add: Oh, in the QT SDK documentation would drinstehen how the frames are stored in memory or what to look your own functions to access them.
I have the drawers really no preference, because I either read about "new posts since last visit", "Recent Posts" in the left column, or "answers to their own contributions," the forum. In the first two cases, double posts show up twice. Sometimes I think, "Not even the grasp of the" or "He wants to have's with all the violence" and omit the contributions simple.
Good luck
The fat Stefan
