I’ve been using my AE CS4 to create stills since my old Photoshop no longer functions and funds not available for the newer copy.
It works but I haven’t found the right combinations (if any) to export the frame with high quality, especially the text. Have tried: export sequence; jpeg, etc., render; as jpg, tiff, mov, psd, etc. Even tried converting text to a shape as well as trying 8 and 16bpc. They all come out with low quality.
