Serious problems with cropping in RedAlert/RedRushes

[Adam Hunt]

We are currently prepping for a shoot using the red with a 2.35:1 aspect ratio. We need offline Quicktime files at 1920x1080 letterboxed to 2.35:1 with burned in timecode in the bottom black bar. This seemed easy enough to do with RedRushes however everything goes awry when I enable cropping.

Without cropping enabled everything works fine, but when I flip it on and plug in some cropping for 2.35:1 (based on debayer not full res as instructed) the output time slows to a crawl (say 1/10 the speed at best) and what I get as output is a 1920x1080 QT that flashes various frames of solid color with no sign of the original image. The timecode however is still burned over the QT as normal.

I have tried using the rendering window in RedAlert, and again, everything goes fine until I enable cropping. RedAlert however simply crashes instead of giving me bad output.

This is needless to say a big problem for our workflow when shooting 2.35:1. Is there any chance this is a known issue and will be corrected shortly?

Thanks.

FYI - MacPro 8-core 3Ghz, 10GB RAM, OS 10.5.6, QT 7.6 (472), RedAlert 3.60, RedRushes 3.60 (1)

what format did you shoot and what numbers/setting are you using for the crop?

 

[Adam Hunt]

We are working from the raw 4096x2048 R3D files. Originally the crop settings I used were:

Y Offset: 167
Height: 1714

This caused both RedAlert and RedRushes to crash. I then found out that crop is based on the DeBayer resolution so I used this instead (for 1/4 res):

Y Offset: 42
Height: 428

At that point RedRushes no longer crashed but gave me the garbage output I described instead. RedAlert continued to crash. I tried various other settings for the crop and it seems to have no effect, cropping enabled simply doesn't work and the same settings with cropping off works fine.

You might want to try Clipfinder (link in my signature).

Can you send a screen grab of your settings in the render window in REDalert?
I think I'm doing the same as what you're doing but don't see any problems.

OS 10.5.6, QT 7.6 the problem maybe Deanan?

Adam, Have you tried uninstalling and re-installing RedAlert! ?
