Frequently Asked Questions
Apple ProRes is a high-quality, lossy video compression format developed by Apple. It’s designed for professional video editing workflows, offering excellent image quality with manageable file sizes. Use ProRes when working in Final Cut Pro, Avid, or other professional editing systems that support it.
ProRes 422 HQ offers the highest quality with larger files, ProRes 422 provides excellent quality for most professional work, ProRes 422 LT is optimized for efficient storage while maintaining broadcast quality, and ProRes 422 Proxy is designed for offline editing with the smallest file sizes.
ProRes generally requires more storage than BRAW at equivalent quality levels. For example, 4K ProRes 422 HQ uses approximately 220 MB/s compared to 4K BRAW 5:1 at 120 MB/s. However, ProRes offers broader compatibility across editing systems.
Yes, while ProRes was developed by Apple, it’s now supported on Windows through various applications including Avid Media Composer, Adobe Premiere Pro, and DaVinci Resolve. Most modern NLEs can read and write ProRes on Windows.
ProRes RAW is Apple’s RAW video format that combines the flexibility of RAW with the performance of ProRes. It offers greater color grading flexibility than standard ProRes while maintaining efficient file sizes and smooth playback performance.
Yes, ProRes 4444 supports 12-bit color and an alpha channel (transparency), making it superior for VFX and high-end graphics. ProRes 422 HQ is 10-bit and does not support alpha channels, but it is more storage-efficient for standard video.
Absolutely. ProRes is highly scalable and supports resolutions up to 8K and beyond, making it future-proof for high-resolution cinematography and broadcast standards.
ProRes is an intra-frame codec, meaning each frame is compressed individually. H.264 is inter-frame (long GOP), which requires more CPU power to decode. ProRes provides much smoother playback and faster scrubbing during the editing process.
For the best quality on YouTube, uploading in ProRes 422 or ProRes 422 HQ is recommended. While the file sizes are larger, it prevents “double compression” artifacts when YouTube re-encodes your video.
Yes, newer iPhone Pro models (iPhone 13 Pro and later) support recording directly in Apple ProRes, allowing mobile creators to capture professional-grade footage for high-end post-production.
