These frame size options seem very strange to me.
High resolution: 1536 x 790 - 37.5% of 4K, 40% of UHD source media. Low resolution: 1024 x 540 - 25% of 4K, 26.6% of UHD source media. There, Adobe adds H.264 as a proxy choice and defines the compressed frame sizes: To see frame size definitions and other proxy format options, create proxies on import using Premiere’s Media Browser. While this menu emphasizes creating ProRes proxies, the specific frame sizes and compression settings not actually defined. When creating proxies by right-clicking an existing clip in the Project panel, Premiere offers five options. All proxies are created by Adobe Media Encoder. Premiere creates proxies on import, after files are imported into the project file, or by linking to existing proxies. NOTE: Here’s my review of the OWC Thunderblade. (I use the remaining SSD blade as my Time Machine drive.) The Thunderblade has a maximum speed around 2,500 MB/second. This engine does not exist in Intel systems.įor Premiere, I’m running the current version: 23.2.0.įor external storage I’m using an 8 TB OWC Thunderblade which I’ve configured into a 3-drive SSD RAID. NOTE: The M1 Pro SoC includes a Media Engine, which encodes or decodes ProRes, H.264 and HEVC media in hardware. It might handle more proxy streams, though.) (An M1 Max would even faster, but would still run into limitations due to the maximum speed of Thunderbolt. (Maximum CPU speed is around 1,000%.)Īdditionally, Adobe Media Encoder is slower than Apple Compressor in creating H.264 proxy files and FAR slower creating ProRes 422 proxy files.įor this article, I’m using a 16″ M1 MacBook Pro with an M1 Pro chip and 32 GB of RAM. In fact, when editing proxy files, the CPU is running less than 100% capacity. These limitations seem to be Premiere-based because, during editing, the CPU is running at less than 225% capacity. Less than 15 streams of H.264 proxy media at 50% frame size. Less than 15 streams of ProRes 4444 media. 35 streams of 4K ProRes 422 Proxy media at 50% frame size. Here are the limits before dropped frames start: Though Adobe Premiere Pro supports multicam editing, it has limitations. How Many Multicam Streams of 4K Media Can Apple Final Cut Pro Edit?. How Fast Media Storage Needs to Be for 4K Multicam Editing in Adobe Premiere Pro. In this tutorial, I look at Adobe Premiere Pro. This month, I’m looking at how well Apple Final Cut Pro and Adobe Premiere Pro support multicam editing in terms of streams and storage bandwidth.
