I'm having a few issues with masking and /or cropping.
I create a new comp, create a new solid layer, select the layer, then the rectangle tool and yes, the masking works as it should. I can only see the content inside the mask.
Ok, now here's my problem. From the effects I'm using "text >numbers" to ultimately create a countdown timer. However when I try to mask part of this. Nothing happens. Here's a pic
Please can someone tell me what i'm doing wrong?!
Enable the Composite on Original option or pre-compose. Happy greetings from teh AE render pipeline. you should read up on this stuff.
You're seeing this due to AE's rendering order - it renders masks before effects, which means your Numbers effect is being rendered after the mask has clipped its layer. You can apply a mask to your Numbers effect by going to the 'Compositing Options' under your Numbers effect in the timeline, clicking the + sign, then choose your mask from the 'Mask reference' drop-down.
BTW if you just want to remove these two zeros, you can reduce the decimal places parameter
and for a counter I do recommend using expressions, rather then numbers effect which is not that flexible. here's a good resource for it:
