Because the smallest increment in timecode is a whole rather than a fractional frame, timecode running at 29.97fps cannot account for the 0.03 frames that are missing in every second so a device running timecode at 29.97fps runs a little slower than a normal clock. In Record Run, the recording device runs timecode only when the camera is recording. Timecode and Frame Rates: Everything You Need to Know ›Īn in-depth look at timecode, how it works (both on set and in post), and the crucial role that frame rates play in using it correctly.īy giving every frame a unique identifier based on the length of the recording or the time at which it was recorded, you can find any specific frame in a recording if you have its timecode reference. When you use the timecode media handler to work with time values, the media handler uses timecode records to store the time values. Given a timecode definition, you can freely convert from frame numbers to time values and from time values to frame numbers. If you were creating a movie from an NTSC video source recorded at 29.97 frames per second, using SMPTE timecodes, you would format the timecode definition structure as follows. Contains a timecode definition structure that defines timecode format information. The timecode description structure defines the format and content of a timecode media sample description, as follows. Each sample in the timecode track provides timecode information for a span of movie time. The timecode format information provides QuickTime the parameters for understanding the timecode and converting QuickTime time values into timecode time values (and vice versa). timecode format information (this specifies the characteristics of the timecode and how to interpret the timecode information). A movie’s timecode is stored in a timecode track. Timecode tracks allow you to store external timecode information, such as SMPTE timecodes, in your QuickTime movies. Introduces some of the basic concepts you need to understand when working with QuickTime movies. The properties of built-in and custom settings that use this format are located in the General, Video, and Audio inspectors (described below). However, the built-in settings analyze your source media and assign optimal properties to ensure the best possible transcoding results. Note: You can also create custom settings that use the QuickTime Movie transcoding format, including settings that use the HEVC encoder. (To transcode using HEVC, your computer must be running macOS 10.13 or later HEVC playback requires a recent-generation Apple device running macOS 10.13 or later, iOS 11 or later, iPadOS 13 or later, or tvOS 11 or later.). You can change the codec in the Video inspector. When you add a QuickTime Movie-based setting to a job, Compressor chooses the appropriate codec. Settings based on the QuickTime Movie format offer a variety of encoders, including H.264 and HEVC (High-Efficiency Video Coding, also known as H.265 ). See Create optimized and proxy files in Final Cut Pro. This format encodes video files for many uses, including a proxy workflow in Final Cut Pro. In Compressor, many of the built-in settings in the Settings pane, including the YouTube & Facebook, ProRes, and Proxy settings, use the QuickTime Movie format. In Compressor, settings based on the QuickTime Movie format offer a variety of encoders, including H.264 and HEVC. view details › Related content QuickTime Movie settings in Compressor › Then the video starts playing, press the shortcut key “E” on your keyboard to view the video frame by frame. From the pop-up menu, choose Open with > VLC media player. Find the video you want to play frame by frame and right-click on it.
