Vimeo video hd12/8/2023 ![]() Data rateįor consistent results, you may choose to encode your audio at 320 kb/s CBR although this is higher than necessary to achieve transparent audio quality. Audio codecįor consistent results, we recommend using AAC-LC (Low Complexity AAC) for the audio codec. Below we've included our key recommended settings for encoding your audio. Similar to video codecs and compression, the codec you use to compress the audio of your video can affect how it sounds and the file size. With Interlaced scanning, lines of visual information are alternated and only half of a frame’s visual information is transmitted at a time. With progressive scanning, all of the lines that make up a single frame are transmitted. ⚠️Note : Stereoscopic video should be uploaded with the left and right view stacked on top of each other as 4096 x 1024 (4:1 aspect ratio) for each eye.Ī progressive scan indicates the specific pattern that lines of visual information are displayed across the viewer’s screen. Standard Definition (SD) 16:9 aspect ratio Standard Definition (SD) 4:3 aspect ratio ![]() Below are some of the most common formats: ![]() We recommend compressing your video with a pixel aspect ratio of 1:1, or square pixels. Given the numerous kinds and sizes of screens on which your audience may be viewing your video, it's important to consider the resolution. 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.
