Final Cut Pro may drop video frames in cases where there is not enough system memory available. For instance, if you're editing an uncompressed 8-bit or 10-bit high-definition codec, and you're monitoring video externally via a PCI or PCI-E video interface, Final Cut Pro may drop frames occasionally if your computer does not have sufficient system RAM.
Install additional RAM in your computer to increase the amount of memory available to Final Cut Pro. Note: The following table corresponds to the memory recommendations for Final Cut Pro only. If you run other applications at the same time as Final Cut Pro, they will allocate additional memory from the system, reducing the amount available to Final Cut Pro.
| HD formats: | Suggested RAM |
| HDV formats | 2 GB |
| Compressed HD formats | 2 GB |
| Uncompressed HD formats | 4 GB |
