Occasionally in some images I'm find certain diagonal lines have jagged pixely edges, they're there before any sharpening or upsizing... and suggestions on how to get rid of them?
See the pixelation in the twig? Any ideas on how to avoid this from happening? I'm not just picking nits, it shows up in prints and is bothering me. The rest of the image looks fine...
I shoot raw, process in ACR, then PS, flatten, upsize with bicubic (I've tried others, genuine fractals for example, which IMO produces an ugly fractaly effect for natural scenes) and sharpen using various methods. But the problem is that the jaggies are there in the original file after conversion...
I first opened a threshold adjustment layer and adjusted the slider to isolate mainly the white jagged line. I copied that and made a layer mask on a blank layer and filled the layer with white. Then went to Select > Refine edge to tweak the mask a little.
what camera are you using? this looks like the usual thing that comes out of a camera with an antialiasing filter that is too weak. do other RAW converters show the same problems? if so, your only long term solution is to change cameras.

I'm using a 5D, when I can get my hands on a 5DII I'll be upgrading to that.. if it's better it's better, if not it's not.. there's not much choice in terms of affordable high quality FF dSLRs...
I haven't tried any other RAW converters, but I really like the GUI and control in ACR and am very happy with everything else it does..
One quick way to sort out jagged pixels on diagonals is to use the Blur tool in Photoshop. Just select a small soft brush then shift click on the diagonals to get a nice straight line, give it a try .
