CRF is an encoding mode that adjusts the file data to achieve a selected quality level rather than a specific data rate.īit rate (also known as data rate) determines the visual quality of the video and its file size, by measuring the amount of data used to encode a single second of video. For example, ProRes HQ for 1080p at 29.97 fps has a target bit rate of 220 Mbps in Final Cut.

For ProRes, follow the standard presets in your video editor to export your file.

⚠️Note : If you have the ability to set the constant rate factor (CRF), we recommend setting it to 18 or below. Video quality and corresponding bit rates can be found in this table: You can experiment with different rates if your file is too large or you’re not happy with the quality of your source file. If your video editing software gives you the option, choose a “variable” bit rate and select a value from the ranges below. Important: We recommend a constant frame rate throughout your entire video. If your video’s frame rate is automatically reduced, you may notice lower quality or choppy playback. If your footage exceeds 60 FPS, we will automatically reduce the frame rate. When preparing your video for upload, it’s best to maintain the video’s native frame rate when compressing your video. Audio Codec : AAC-LC (Low Complexity AAC)įrame rate is the measurement of how quickly a number of images (or frames) appear within a second, commonly referred to as FPS (frames per second).Scan type : Progressive, and recommend deinterlacing videos.Color Transfer Characteristics : F or HDR videos we only support the PQ (SMPTE 2084) or HLG transfer function.Color Primaries and Matrix Coefficients : All accepted but we recommend BT.2020 (Rec.Bit rate : Choose variable if possible and follow ranges based on your video’s definition.Frame rate: Keep native frame rate and choose constant frame rate.Video Codecs: H.264, Apple ProRes 422 (HQ), or H.265 (HEVC).See Video, Color, and Audio guidelines after this list for more exhaustive information.
