What are the main limitations of using DaVinci Resolve on an iPad Pro compared to a desktop

Hardware Limitations

1. RAM and Performance: iPads, especially those with 8GB of RAM, face significant limitations when handling large projects. For instance, exporting footage larger than about 7.6 GB can be problematic, leading to errors like timeouts during rendering[1]. In contrast, desktops can be equipped with much more RAM, allowing for smoother handling of large files.

2. GPU Capabilities: DaVinci Resolve is heavily reliant on GPU power for rendering and editing tasks. While iPads have powerful GPUs, they are generally less capable than those found in desktop computers, which can be upgraded with high-end GPUs like the NVIDIA 3080 series[3]. This limits the iPad's ability to handle demanding video formats and resolutions.

3. Storage and File Handling: Although iPads have fast internal storage, they lack the expandability and flexibility of desktop systems, which can easily accommodate multiple external drives and storage solutions. This can limit the iPad's ability to handle large projects efficiently[1].

Software Limitations

1. Feature Set: The iPad version of DaVinci Resolve lacks some features available on the desktop, such as certain effects and advanced project collaboration tools. Features like ProRes support and some Resolve and Fusion effects are disabled or limited on older iPads[5].

2. Project Complexity: While the iPad version is excellent for rough cuts and color grading, it is not ideal for complex projects or precise editing tasks. This is due to both hardware limitations and the app's design, which prioritizes portability over full-scale professional editing capabilities[9].

3. User Interface and Workflow: The iPad app is optimized for touch input and lacks the full range of pages available on the desktop version, such as the Fairlight page for audio editing. Users must rely on keyboard shortcuts to access additional pages[11].

4. External Device Support: While the iPad supports external devices like keyboards and displays, it lacks the comprehensive connectivity options available on desktops, which can connect multiple monitors, audio interfaces, and other peripherals.

Practical Considerations

1. Export and Rendering: The iPad's limitations in handling large exports mean that users may need to transfer projects to a desktop for final rendering, especially for projects exceeding certain size or complexity thresholds[1].

2. Collaboration and Compatibility: Projects started on an iPad may not fully translate to desktop versions due to differences in supported features and effects, which can complicate collaboration across platforms[5].

In summary, while DaVinci Resolve on the iPad Pro offers a powerful mobile editing solution, it is best suited for smaller projects, rough cuts, and color grading. For more complex professional work, a desktop setup remains the preferred choice due to superior hardware capabilities and a more comprehensive feature set.
