To view a clip's time at any point in your script, temporarily insert an Info or ShowTime statement.įor convenience, AudioTrim can be called in four slightly different ways:ĪudioTrim(clip, float start_time, float end_time) The resulting clip starts with time = 0.0, and this must be taken into account when making additional edits to that clip. Trims on clips with video are accurate to the nearest whole video frame.ĪudioTrim cannot trim a clip if there is no audio.Trims on audio-only clips are accurate to the nearest audio sample.This is most useful for audio-only clips, where "frames" have no meaning anyway, and you may want to edit with finer precision than whole frames (at 30fps, 1 frame=33.3ms).Īll time arguments are in seconds, floating-point. This feature is useful in avoiding unexpected boundary conditions in your user functions.ĪudioTrim (from Avisynth v2.60) trims a clip based on time, not on frames. Unlike the num_frames syntax, the length syntax has no discontinuous boundary values: length=0 means return a zero length clip.
For example, Trim(3, length=5) is equivalent to Trim(3, -5) both return frames 3, 4, 5, 6 and 7.Returns a clip starting at first_frame and running for length frames. This feature is useful in avoiding unexpected boundary conditions in your user functions. Unlike the last_frame syntax, the end syntax has no discontinuous boundary values: end=0 means end at frame 0.end default = 0 must be >= first_frame.For example, Trim(3, end=7) is equivalent to Trim(3, 7) both return frames 3, 4, 5, 6 and 7.Returns a clip starting at first_frame and running up to and including frame end. For example, Trim(0, -4) returns source clip frames 0, 1, 2 and 3.With a negative value for the second argument, you get a clip starting at first_frame and running for num_frames frames. Trim(clip, int first_frame, int - num_frames ) You should use pad=false when the soundtracks being joined were originally contiguous – compare to UnalignedSplice. Otherwise the tail of a short audio stream is left so. True by default, pad causes the audio stream to be padded to align with the video stream. If you set last_frame to 0, you will get a clip starting at first_frame and running to the end of the clip.Remember, AviSynth starts counting at frame 0.For example, Trim(3, 5) returns source clip frames 3, 4 and 5.Returns a clip starting at first_frame and running up to and including last_frame. Trim(clip, int first_frame, int last_frame ) To view a clip's frame number at any point in your script, temporarily insert an Info or ShowFrameNumber statement.įor convenience, Trim can be called in four slightly different ways: The resulting clip starts with frame number 0, and this must be taken into account when making additional edits using that clip. Use AudioTrim (from AviSynth v2.60) for that case for versions prior to v2.60, you must AudioDub your audio-only clip to a video clip and Trim that. Trim cannot trim a clip if there is no video. Trims a clip – removes frames from one or both ends.
