I am editing a commercial with several high resolution still photos. I added text to the panned and scanned photos and can't render. I think it's a memory problem. The error message I get: "Codec not found. You may be using a compression type without the corresponding hardware card."
I am using a Mac Book Pro 13" with 2.3 GHz Intel Core i5 processor with 4 GB 1333 MHz DDR3 memory (Mac O/S 10.6.8). My compression under sequence settings is Apple ProRes 422.
I had this problem and it was fixed by changing timeline render settings (apple+zero) to 8-bit rather than 10bit. If you change the still size in photoshop you will need to redo all your moves/resize in FCP.
