BMD – PrePro2.0 Compression Export Problems
Hi!
I am noticing some artifacting in my PrePro2.0 exports to TIFF/TGA Seq. When I acquire footage via Digibeta SDI to the Decklink Extreme, the 10bit video looks great. The problem starts when I export the AVI or part of the AVI to a tiff/tga seq. If you import the image seq and the AVI in a compositing software like AFX or Fusion, you start to see some blockiness on the edges of the image seq which is not seen in the AVI. This is most apparent in the blue channel of the image. The edges look compressed similiar to DV compression/blockiness. But when I look at the avi, it’s fine. Another thing that’s strange is when I export a short part of the AVI to a new BMD format AVI, the image looks fine and identical to the source.
Also, when I try to export the AVI to TIFF/TGA seq in a compositing software, there is no blockiness/artifacting.Anyone care to test this out or give a solution? Thanks

Hi Adrian,
Can you please retest this using the current DeckLink 5.7.2 drivers which are available from software downloads. If the problem still occurs when exporting from a 10-bit sequence, please capture at 8-bit and then export to a TIFF/TGA sequence. Does the same problem occur or does it look as it should?

Hi Luke,
It seems to be happening on the image sequences exported from 10bit only. The exports from 8bit look fine. I’m still using the 5.6 drivers on this test. Another thing i found though is that the 8bit avi exports are crashing AFX7. I haven’t used 8bit avis in a while so I just found this out now. Is this an 8bit/AFX7 bug or did I have a bad avi export? Will try the 5.7 drivers tom. Thanks Luke.

Have you updated AE to 7.01 (regarding the 8-bit crash)?

Hi Adrian,
[Adrian Tecson] “It seems to be happening on the image sequences exported from 10bit only. The exports from 8bit look fine. I’m still using the 5.6 drivers on this test.”
That’s interesting and makes some sense. Can you see if it still happens with the current DeckLink 5.7.2 drivers? If so, we’ll check it out.

Adobe have fixed this problem and we have a support note about it named Serious error when opening AVI’s in After Effects 7.0.

Hi Luke/Max,
I updated my AFX to 7.01, no more crashes on 8bit. Thanks for the tip.
The problem still remains though. Updated to the latest 5.7.1 BMD drivers and re exported the footage with the same result. I could email sample of the quality difference in exports between PP2.0 and AFX7 coming from the same AVI if you need to see it. Hope you guys can fix it for the next driver update. Thanks Luke. -
Hi,
same problem here.
8 Bit BMD PAL AVI crashes After Effects 7 (german version) after import it into AE7.
But update via Bridge is not possible ;-( , because Adobe Bridge didn
