After Effects video preview via firewire



Frage von Christian27:
März 2009

Hello,

I have a "small" problem with the video preview (via Firewire) in After Effects ...

If I have firewire will output the video preview and play in a loop, then komt it often (almost always) after some time that such staggered blocks are visible (artifacts) ...

This happens mostly when the preview loop was played several times (so after about 5-10 iterations).

Can someone of the times you try, whether synonymous with you so?

I got this error at times reported to Adobe, but it will certainly take up as many times a bugfix rauskommt.
The content is quite annoying if always blocks come.

Bin mal gespannt if only for me, or other synonymous.
(As I said the RAM-loop run, then after 5-10 repetitions of the artifacts come)

Liebe Grüße
Christian :-)

Hi :-)

So s.dem firewire device (a Canopus ADVC-110) can not lie ...
Times that I have an additional PCI card with firewire ports built in order that auzuschließen not the internal firewire port is causing the problem ...

And just as it is,
s.den Firewire ports on the PCI card is the problem exactly the same ...

Furthermore, I have synonymous times instead of the Canopus ADVC-110 a MiniDV-Cam with DV - In connection:
Even there, the blocks ...

Do you have the times when you tried?
Come da (after about 10 iterations) does not block?

Many greetings
Christian :-)








Antwort von Christian27:

Hi :-)

I want to again ask for the video preview problem ...

Has anyone of you tried out the times, because of the blocks?

Many greetings

Antwort von Mylenium:

Mmh, but then this is already stupid. Generally, however, have any artifacts in the digital data stream, the only question is where it happens. Ursrpünglicher My idea was just that, by the frequent overwriting anything with identical information in FW buffer verhakelt. If it is not, it might actually only in the memory itself or the graphics card to pass. Either you another radio program, or between the graphics card has a problem in the way that it buffers too much and then the normal buffer fragmented because imemr not the whole screen is redrawn. Eventually, something in the art by heavy telediagnosis to say. But I would in any case try, s.den performance of the graphics card settings rumzudrehen. Already quite possible that you have hardware acceleration with less keien artifacts get more ...

Antwort von Christian27:

Hello,

So now I've found some people that the times have asuprobiert.
Is all the same problem ...
Always, the artifacts, either immediately or after some time (after a few loops) ...

It really seems to be a software problem to act.
I would have previously synonymous times a Canopus Video - Out-plugin (synonymous to the output of the video preview via firewire) and it works cleanly (no artifacts) ...
(The reason why I use the Canopus plug-in no longer want to use is that it is extremely eats memory. When Canopus Plugin often get only 2 seconds preview in AE about 10 sec)

I got the error reported times at Adobe, but I think the customers did not want to help ... The point is only that we should file a bug report on the U.S. Adobe Web site reported to me because they can not help ...
So I then tried with my broken English that explain the error. Bin mal gespannt whether da mal ein bugfix rauskommt ;-))

Greeting
Christian :-)
