Sent back to Final Cut Pro 7
When exported directly out of FCP as a raw .mov file, everything looks just fine, but as soon as I try to convert it into something smaller with a codec like H.264 I get artifacts, especially around the edges of light on walls etc. Quality is really bad in any case.
I usually export from Final Cut Pro 7 and run it through Episode with the setting:
H264 MOV 1920x1080 16x9
This usually does the job, but I'm at a loss here.
try turning up the data rate or quality settings in Episode. Generally speaking, scenes with more complexity require higher data rates, or you start getting artifacts like you describe. Settings that work well for some material may not do the trick on other stuff, so you may need to do some tests until you find a combination of settings that work well and give reasonable file sizes.
