![]() However, as a result of its multimedia heritage, the vast majority of H.264 implementations come with annoying drawbacks: inability to crawl backwards frame by frame, jerky images in fast forward and fast rewind, latencies and unnecessary costs. For any audio uploaded with a sampling rate of over 48kHz, we will resample your audio to 48 kHz or below.For the security industry the major attraction of the H.264 standard is the prospect of high levels of compression and low storage costs. If your working setting is already less than or equal to 48 kHz, leave it as is. Sample rate: 48 kHzįor best results, set your audio sample rate to 48 kHz. Data rate: 320 kbit/sįor best results, encode your audio at a constant rate of 320 kbit/s. Codec: AAC-LC (Advanced Audio Codec)įor the best results, we recommend using AAC-LC (low complexity) for the audio codec. For any number of channels above 2, we will downmix your audio to 2 channels. Audio Channels: Stereoįor best results, we recommend 2-channel Stereo audio. For the best results, we recommend deinterlacing videos prior to upload. Vimeo converts all videos to progressive for playback. ![]() For high dynamic range (HDR) videos, your file needs to have a bit depth of 10 or greater in order to be considered HDR on Vimeo. We support various bit depths, but we recommend a bit depth of 10 or greater for the highest quality results. This metadata is usually added automatically in post-production. If using the PQ (SMPTE 2084) transfer function, please include the following metadata to ensure the most accurate display of your video’s colors on all devices: Mastering Display Color Volume metadata (SMPTE 2086) and Content Light Level Information metadata (CEA 861.3). We support a wide range of transfer characteristics for standard (SDR) videos, but for HDR videos we only support the PQ (SMPTE 2084) or HLG transfer function. You can use the same value for both color primary and matrix coefficients. We support all color primaries and matrices, but we recommend BT.2020 (Rec. Note: some software may not offer control over your color settings. ![]() Colorįor the most accurate color display on Vimeo, we recommend uploading a file that contains color space information. * 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. We recommend compressing your video with a pixel aspect ratio of 1:1, or square pixels. Videos come in all shapes and sizes but these are some of the most common formats. 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. * If you have the ability to set the CRF (constant rate factor), we recommend setting it to 18 or below. 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. While we accept many frame rates, these are the most commonly used: FPSīit rate (also known as data rate) controls the visual quality of the video and its file size. Always choose a “constant” frame rate instead of a “variable” frame rate. Important: We recommend a constant frame rate throughout your entire video. 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. This video codec supports resolutions up to 8K and high dynamic range (HDR) videos. ![]() H.265 or High-Efficiency Video Coding (HEVC) is the successor to H.264, which offers a smaller sized file with high visual quality at the cost of increased encoding time. If you notice quality issues with your H.264 videos and have ample storage space on your Vimeo account, using ProRes may produce a better result. This professional-quality codec ensures high quality for your encoded video but typically results in a much larger file size than H.264. Be sure to choose the "High Profile" H.264 setting instead of "Main Profile." Please note that the H.264 video codec only supports resolutions up to 4K. It's a great starting point for encoding your videos as it ensures you'll get the most out of your upload quota while minimizing upload and conversion times. H.264 is a standard codec that balances high visual quality with efficient file size. We accept most major codecs, but for best results, we recommend using one of the following: H.264 A codec is a format in which your video is encoded. ![]()
