Sometimes certain camera original formats that have high bit-rates or use a codec that take
s longer to decode. The "Create optimized media" option can provide better performance during editing, faster render times with better image quality, and faster export. Final Cut Pro X can reduce or eliminate dropped frames by transcoding this media to ProRes 422 in the background while you organize or edit in the foreground.
Some camera original formats don't benefit from improved performance when transcoded to ProRes 422. When you select these formats, the "Create optimized media" option will be unavailable. Native camera media formats that you can edit in Final Cut Pro X with good performance include:
- DVCPRO HD
- XDCAM HD/EX/HD422
If you experience playback issues with a media format while working in Final Cut Pro X, consider creating optimized media (if the option is available). This enables better editing performance of that media in Final Cut Pro X. You can create optimized media during import or at any time later by control-clicking the media file(s) in the Event Browser and choosing Transcode Media from the contextual menu.
