Apple ProRes 422 is a professional intraframe-coded 10-bit video codec with 4:2:2 chroma subsampling for acquisition, editing, and post-production.
ProRes 422 is a professional video codec developed by Apple for recording, editing, and post-production. It is not lighting or grip equipment, but technically belongs to the camera and post-production world: Many cameras (e.g., from ARRI, Blackmagic, RED, Sony, Canon, as well as Pro-series iPhones) record directly in ProRes, and editing software like Final Cut Pro, DaVinci Resolve, Premiere Pro, and Avid Media Composer work with it natively.
ProRes is an intra-frame coded codec (each individual frame is compressed completely and independently, without inter-frame dependencies). This facilitates cutting, trimming, and playback because each frame can be decoded on its own. It operates with variable bitrate (VBR) and adjusts the data amount depending on the image content. The designation "422" refers to 4:2:2 color sampling: full luminance resolution (luma) with horizontally halved color resolution (chroma).
"ProRes 422" refers to both a specific variant (the standard profile) and the overarching 4:2:2 family. All four variants use 10-bit color depth and 4:2:2 sampling, and differ primarily in their compression ratio or data rate. For higher color depth or an alpha channel (4:4:4:4), ProRes 4444 and 4444 XQ exist separately and do not belong to the 422 family.
| Variant | Target Data Rate (1920×1080, 29.97 fps) | Typical Use |
|---|---|---|
| ProRes 422 Proxy | approx. 45 Mbps | Offline editing, lightweight proxies at full resolution |
| ProRes 422 LT | approx. 102 Mbps | Space-saving, broadcast workflows with reduced data volume |
| ProRes 422 | approx. 147 Mbps | Standard mastering and editing format, good balance |
| ProRes 422 HQ | approx. 220 Mbps | Demanding recording, color grading, VFX |
In practice, ProRes 422 (often the HQ variant) is a common recording format for external recorders (e.g., Atomos, Blackmagic Video Assist) and in-camera recording. It delivers visually high-quality results with significantly more manageable file sizes than uncompressed or RAW material and is widely compatible as a post-production codec. The 10-bit depth and 4:2:2 sampling provide sufficient latitude for color correction, compositing, and keying. For offline editing on less powerful hardware, the Proxy and LT variants are used, while final delivery often occurs via ProRes 422 or 422 HQ.
Ich schätze ProRes 422 für die saubere 4:2:2-Farbauflösung, die mir beim Grading mehr Flexibilität in Hauttönen gibt als 4:2:0-Formate. Die 10-Bit-Tiefe verhindert Banding in Farbverläufen, besonders bei Himmel-Aufnahmen oder LED-Wall-Drehs. Allerdings bedeuten die 147 Mbps bei 1080p, dass meine Speicherkarten schnell voll sind – bei einem 12-Stunden-Drehtag rechne ich mit 800 GB Material.
ProRes 422 gibt mir die Sicherheit, dass mein Material in der Post verlustfrei bearbeitet werden kann, ohne Qualitätsverluste durch mehrfache Transkodierung. Die 10-Bit-Farbtiefe ermöglicht drastische Look-Änderungen im Grading – ich kann warme Szenen nachträglich kalt färben ohne Artefakte. Für dokumentarische Projekte ist der Codec ideal, da er schnelle Turnarounds im Schnitt ermöglicht.
ProRes 422 kostet mich etwa 30% mehr Speicherplatz als H.264, aber spart Geld in der Post durch wegfallende Transcoding-Zeit. Ein 90-Minuten-Film in 1080p benötigt circa 800 GB Master-Speicher. Die universelle Kompatibilität reduziert technische Probleme zwischen verschiedenen Post-Facilities, was Zeitverzögerungen verhindert und mein Budget schützt.
