Mouse flickering and white circle with X on SD playback on 8 core mac pro with Raid 5
Hey guys,
I posted a thread a few days ago about our Mac Pro being very slow and only using 10-30% of it’s CPU.
I was occasionally getting this before and now it is happening again. In the browser I am playing back a SD clip and the mouse is kinda flickering back and forth, I have a white cricle with black x in the upper right and the video is stuttery.
I have a raid 5 setup that tested around 200 MBPS a month ago (new), a 8 core 3.2 ghz Mac Pro with 10 GB ram.
What could be causing this?
Thanks

Ok I figured out that a bunch of the clips from the same shoot (XL2 to FS4) play just fine. When I went to check the properties in FCP it says that the ones acting up have a square pixel aspect ratio and field dominance set to “none”.
The good clips have the field dominance set to “lower” and the pixel aspect ratio set to “NTSC – CCIR 601”
I must have used a script for quicktime to change the aspect ratio and then re-saved them I guess. I don’t know how to change them back though.

Thanks Rafael. Those worked but the video is appearing as 720×540 as well. FCP will not let me change the dimensions back. The script is here https://macosx.com/forums/apple-scripts/298282-applescript-change-quicktime-movie-aspect-ratio.html
Here is a direct download link to the script. All I did was take my normal footage and apply the script (4:3) and I saved it. I normally don’t save it but I guess I did. However, I cannot replicate that result with any other files.

I did not recompress this footage or anything like that, it is just the flags that got changed.

So you need to change the clips parameters in the QT Player properties (Comm-J).
I used to change those properties in QT so the DV Anamorphic would display properly, but when I saved the changes I had problems in FC. FC misinterpret size and pixels aspect.

Rafael – I owe you one!!
Lifesaver!!! Thanks so much for the command j = properties. I could not find that in the menus! I stayed up until 2 am at work here trying to figure this out! I come into work and you have my solution!
Cheers,
Elijah

The big problem is that there is not a manual for QT.
There are many things in the Properties that I really would like to understand what are for and how they work.
In former QT versions the changes in the Properties took effect only when playing with the QT player and had no effects on the QT files in FC. Now is not anymore like that and a change can ruins a whole FC project, so be careful, play with the properties but don’t save the changes.
