Frage von JohnnyFavorite:
I want to shoot HDV (1080i) and the format before the cut in 1024x576 convert. Is there an intermediate codec, lossless Resolutionnahezu these stores? Otherwise I would feel about using anamorphic 16:9 DV codec go. The full horizontal Resolutionwäre me, however, prefer to ...
The cut in HDV or uncompressed material (synonymous 1024x576) unfortunately falls flat, because my calculator does not participate. Perhaps there is a solution? Thanks in advance!
Antwort von PowerMac:
Uncompressed is really not that hard ... It relieves the processor even. Only the hard drive is needed. My 250er with S-ATA already creates two 8-bit 4:2:2 streams in real time.

You may your happiness synonymous with a good MJPEG avi codec sample some of the PIC (Pegasus). Such attitudes, one loses only a little more Render generations.
Another - perhaps better - solution is the use of intermediate codecs - such as the Cineform products. Alternative would be weaker, especially for systems synonymous nor the proxy section in question, but of course much of the NLE used depends on how easy or difficult it is.

In American forums is often on QT / Still Image Jpeg swore (approx 80% quality setting). However, the rendering time is much longer than with the Pic-MJPEG ...
Antwort von PowerMac:
Quality 75% not 80%! Up to 75% is in the YCbCr color space with 4:2:2 worked, S.75% have RGB 4:4:4.

Quality 75% not 80%! Up to 75% is in the YCbCr color space with 4:2:2 worked, S.75% have RGB 4:4:4. True, it is true. Although, I had HDV material synonymous than ever Still Image Jpeg-Intermediate with 80-90% probiert + a 75% difference to me is, frankly, not noticed ...

Helps me schonmal next. Thanks guys!

Is there an intermediate codec, lossless Resolutionnahezu these stores? Also, the Lossless codec HuffYUV would perhaps in question.
Antwort von JohnnyFavorite:
One additional question I would have: if these assumptions?
HDV has a Resolutionvon 1440x1080. This makes a color resolution of 4:2:0 for U, V = 720x540. DV on the other hand, has only one color of U, V = 360x288. Stay in the software conversion of HDV 1024x576 pixels on the HDV color (ie, U, V = 720x540) receive? This would be so nearly the full vertical color resolution is available.
As an intermediate format would FotoJPEG with 75% (for 4:2:2) still suffice, right?
Thanks again!
