Rate stretch tool adobe premiere как включить
Обновлено: 04.07.2024
You can change the speed and duration for one or more clips at a time. Premiere Pro offers several ways to modify the speed and duration of clips.
The speed of a clip is the rate at which it plays back compared to the rate at which it was recorded. The duration of a clip is the length of time it takes to play from the In point to the Out point. You can set a duration for video or audio clips, letting them speed up or slow down to fill the duration.
Use one of the following options to change the speed or duration of a clip:
You can apply Optical Flow only from the timeline or Export Settings dialog box, and not from the Project panel. Timeline Search provides you with advanced search options that let you find and manage clips in complex timelines. For more information, see Find assets.
In the Timeline panel or Project panel, select one or more clips. Ctrl-click (Windows) or Command-click (Mac OS) clips to select a non-contiguous group of clips in the Project panel.
Choose Clip > Speed/Duration or right-click over a selected clip and choose Speed/Duration .
You can apply Speed/Duration changes at the Project clip level or at the Sequence clip level. Changes made at the project level are respected when adding new instances into a sequence. It is different from master clip effects though, because Speed/Duration changes are not ripped into existing instances of that clip in your sequence.
Do any of the following:
- To change the duration without changing the speed of the selected clips, click the gang button so that it shows a broken link. Unganging also allows you to change the speed without changing the duration.
- To play the clips backward, check Reverse Speed.
- To keep the audio at its current pitch while the speed or duration changes, check Maintain Audio Pitch.
- To keep the clips following the changing clips next to them, click Ripple Edit, Shifting Trailing Clips.
- Select a Time Interpolation option for Speed changes: Frame Sampling, Frame Blending, or Optical Flow. (For more information, see the sections below entitled Time interpolation using Optical Flow and Frame Blending)
If the Ripple Edit Tool stops working, make sure that the Composite Preview During Trim option is deselected from the wrench tool in the timeline.
Clips with speed changes are indicated with a percentage of the original speed.
The Rate Stretch tool provides a quick method to change the duration of a clip in the Timeline while simultaneously change the clip's speed to fit the duration.
For example, you have a gap in your sequence of a specific length and you want to fill that gap with some speed-altered media. You do not care so much about the speed of the video, make sure it fills that gap at whatever speed it has to be. Rate stretch allows you to stretch or compress the speed to the percentage needed.
You can change a clip’s speed to fit a duration using the Rate Stretch tool in Premiere Pro. Select the Rate Stretch tool and drag either edge of a clip in a Timeline panel.
You can vary the speed of the video portion of a clip. Use Time Remapping to create slow motion and fast motion effects within a single clip.
Right-click on the clip, and select Show Clip Keyframes > Time Remapping > Speed .
The clip is shaded blue. A horizontal rubber band that controls the speed of the clip appears across the center of the clip. A white speed-control track appears in the upper portion of the clip, just below the clip title bar. If it is hard to see the clip, zoom in to make enough room.
Drag the rubber band upward or downward to increase or decrease the speed of the clip. A tool tip appears showing the change in speed as a percentage of the original speed.The playback speed of the video portion of the clip changes and its duration expands or contracts depending on whether its speed is increased or decreased. The audio portion of the clip remains unchanged by Time Remapping, although it remains linked to the video portion.
When you lengthen a clip in a sequence by slowing its speed, it does not overwrite an adjacent clip. Instead, the clip expands until it touches the edge of the adjacent clip. Adobe Premiere Pro then pushes remaining frames into the tail of the lengthened clip. To recover these frames, create a gap after the clip and trim its right edge to reveal them.
Vary changes to speed or direction with Time Remapping
You can speed up, slow down, play backward, or freeze video portions of a clip using the Time Remapping effect. For example, take a clip of someone walking. You can show the person moving forward quickly, slowing suddenly, stopping mid-step, and even walking backward, before resuming the forward motion.
You can apply time remapping only to instances of clips in a Timeline panel, not to master clips. When you vary the speed of a clip with linked audio and video, the audio remains linked to the video, but remains at 100% speed. The audio does not remain synchronized with the video.
Footage is displayed at constant speed in one direction. Time-remapping distorts time for range of frames within clip.Speed keyframes can be applied in the Effect Controls panel, or on a clip in the Timeline panel. A speed keyframe can be split to create a transition between two different playback speeds.
When first applied to a track item, any change in playback speed on either side of a speed keyframe is instantaneous at that frame. When the speed keyframe is dragged apart and spread out beyond one frame, the halves form a speed change transition. Here, you can apply linear or smooth curves to ease in or ease out the change between playback speeds.
Using Time Remapping, you can perform the following:
It is best to apply time remapping controls to a clip in its own video track. Slowing a portion of the clip makes it longer. If a second clip follows the lengthened clip in the video track, the lengthened clip is automatically trimmed where the second clip begins. To recover trimmed frames, click the Track Select Tool . Shift-drag the second clip toward the right. All clips lying to the right move to the right. Click the Selection tool, and drag the right edge of the lengthened clip to the right, exposing its trimmed frames.
Vary change to clip speed
Right-click on the clip, and select Show Clip Keyframes > Time Remapping > Speed .
The clip is shaded blue. A horizontal rubber band that controls the speed of the clip appears across the center of the clip. A white speed-control track appears in the upper portion of the clip, below the clip title bar.
Ctrl-click (Windows) or Command-click (Mac OS) at least one point on the rubber band to set a keyframe. Speed keyframes appear near the top of the clip, above the rubber band in the white speed-control track. Speed keyframes can be split in half, acting as two keyframes for marking the beginning and end of a speed-change transition. Adjustment handles also appear on the rubber band, in the middle of the speed-change transition.
A. Speed keyframe B. White speed-control track C. Rubber band
Drag the rubber band on either side of the speed keyframe up or down to increase or decrease the playback speed of that portion. (Optional) Press Shift while dragging to limit the speed change values to 5% increments.
Shift-drag the speed keyframe to the left or right to change the speed of the portion to the left of the speed keyframe.
Both the speed and duration of the segment change. Speeding up a segment of a clip makes the segment shorter, and slowing down a segment makes it longer.
(Optional) To create a speed transition, drag the right half of the speed keyframe to the right, or the left half to the left. (Optional) To change the acceleration or deceleration of the speed change, drag either of the handles on the curve control.The change of speed eases in or eases out according to the curvature of the speed ramp.
(Optional) To revert a transition speed change, select the unwanted half of the speed keyframe, and press Delete.
Speed and Velocity values for the Time Remapping effect are shown in the Effect Controls panel for reference only. You cannot edit these values directly there.
Move an unsplit speed keyframe
In a Timeline, Alt-click (Windows) or Option-click (Mac OS) the unsplit speed keyframe, and drag it into its new position.Move a split speed keyframe
In the white control track area of the clip, drag the gray-shaded area of the speed transition into its new position.
Play a clip backward, then forward
Right-click on the clip, and select Show Clip Keyframes > Time Remapping > Speed .
The clip is shaded blue. A horizontal rubber band that controls the speed of the clip appears across the center of the clip. A white speed-control track appears in the upper portion of the clip, just below the clip title bar. If it is hard to see the clip, zoom in to make enough room.
Ctrl-click (Windows) or Command-click (Mac OS) on the rubber band to create a speed keyframe .
Ctrl-drag (Windows) or Command-drag (Mac OS) a speed keyframe (both halves) to the place where you want the backward motion to end. A tool tip shows the speed as a negative percentage of the original speed. The Program monitor displays two panes: the static frame where you initiated the drag, and a dynamically updating frame that reverses playback returns to before switching to forward speed. When you release the mouse button to end the drag, an extra segment is added for the forward playback portion. The new segment has the same duration as the segment you created. An extra speed keyframe is placed at the end of this second segment. Left-pointing angle brackets appear in the speed-control track, indicating the section of the clip playing in reverse.
The segment plays backward at full speed from the first keyframe to the second. Then, it plays forward at full speed from the second to the third keyframe. Finally, it returns to the frame at which the backward motion began. This effect is called a palindrome reverse.
You can create a segment that plays in reverse and doesn't return to forward playback. Use the Razor tool or the Trim tool to remove the segment of the clip with the forward playback section. For more information, see Trimming clips.
(Optional) You can create a speed transition for any part of the change in direction. Drag the right half of a speed keyframe to the right, or the left half to the left.A gray area appears between the halves of the speed keyframe, indicating the length of the speed transition. A blue curve control appears in the gray area.
If the blue curve control does not appear, click in the gray area.
The change of speed eases in or eases out according to the curvature of the speed ramp.
Remove the Time Remapping effect
You cannot toggle the Time Remapping effect on and off like other effects. Enabling and disabling Time Remapping affects the duration of the clip instance in a Timeline. Once the Time Remapping effect has been disabled, all the keyframes are deleted.
To make this panel active, click the Effect Controls tab.
To open Time Remapping, click the triangle next to it.
To set it to the off position, click the Toggle Animation button next to the word Speed.
This action deletes any existing speed keyframes, and disables Time Remapping for the selected clip.
To re-enable Time Remapping, click the Toggle Animation button back to the 'on' position. You cannot use Time Remapping with this button in the 'off' position.
Choose Edit > Preferences > Timeline (Windows) or Premiere Pro > Preferences > Timeline (Mac OS).
For Still Image Default Duration, specify the number of frames you want as a default duration for a still image.
Changing the default duration of still images does not affect the duration of still images that are already part of a sequence or that have already been imported. Reimport the images after you change the default duration to get a different duration for the images.
You can also create a time lapse from still images. For more information, see Create time lapse video from still images.
The Optical Flow feature in Premiere Pro uses frame analyses and pixel motion estimation to create brand new video frames, resulting in smoother speed changes, time-remapping, and frame-rate conversion.
The Optical Flow option in the Time Interpolation menu ( Clip > Video Options > Time Interpolation > Optical Flow ) allows you to interpolate missing frames for time remapping and produce better looking and smoother slow motion from conventionally shot footage.
Since the optical flow library cannot sustain real-time playback, as it happens with the existing Frame Blend function, Premiere Pro uses the time-consuming Optical Flow only for Time Remapping for high quality renders. For low quality or draft rendering, the faster Frame Sample interpolation is used even while the Optical Flow is enabled. To see the optical flow effect, render your sequence. Choose Render In to Out or hit Enter to do that
Optical Flow interpolation is ideal for modifying the speed of clips that contain objects with no motion blur, which are moving in front of a mostly static background that highly contrasts with the object in motion.

Узнайте, как ускорить видео и как обратить клип в Premiere Pro и откройте новый мир творческих возможностей для ваших видеороликов.
После того, как вы научитесь ускорять и реверсировать отснятый материал в Premiere Pro, вы сможете использовать эти методы для создания творческих переходов и визуальных эффектов. Я часто использую эти важные навыки в своих собственных проектах, например, в этом уроке о творческих способах использования переходов с эффектом хлесткое панорамирование.
В одном примере я показываю, как создать ложный бросок и ловлю ножа, когда лезвие приземляется в нескольких дюймах от лица модели. Чтобы заставить иллюзию работать, я объединил два кадра – в одном моя модель «бросала» нож, в другом, она же «ловила» нож. В каждом из этих кадров, используется хлесткое панорамирование, которое служит для маскировки склейки кадров и делает эпизод непрерывным.
Из соображений безопасности и экономии времени я сделал второй кадр обратным. В Adobe Premiere Pro я просто обратил второй клип и вуаля, теперь среди талантов моей модели, это ловить нож на высокой скорости. Чтобы увеличить интенсивность эффекта, я увеличил скорость обоих клипов.
В то время как хлесткое панорамирование взяло всю славу и заслугу за то, что этот визуальный эффект заработал, эффекты ускорения и обратного хода остались незамеченными героями. Давайте подробнее рассмотрим, как можно ускорить и перевернуть клип в Premiere Pro.

В этом примере у меня есть два клипа из моей сцены метания ножей. Как объяснялось ранее, я хочу обратить второй кадр, а затем немного ускорить оба.
Как сделать реверс клипа в Premiere Pro
Выберите клип на вашей шкале времени.
Откройте Clip (Клип)> Speed / Duration (Скорость/Продолжительность) и установите флажок Reverse Speed (Скорость инверсии). Кликните ОК.
Клип будет отображать метку 100%, обозначая скорость и направление клипа.
Давайте пройдемся по нему. Я выберу второй клип и открою Clip (Клип)> Speed / Duration (Скорость/Продолжительность). Теперь я просто нажму кнопку реверса скорости. В следующем разделе мы обсудим некоторые другие параметры, которые вы видите на панели скорости.
Смотрите также: 3 визуальных эффекта, которые вы можете создать с помощью перехода – хлесткое панорамирование (Whip Pan)
После реверса мой клип будет иметь метку -100 процентов, обозначающую как скорость, так и направление клипа.
Как ускорить клип в Premiere Pro
Выберите клипы, которые вы хотите ускорить.
Откройте панель Clip (Клип)> Speed / Duration (Скорость/Продолжительность). или щелкните правой кнопкой мыши и выберите Speed / Duration (Скорость/Продолжительность).
В поле скорости введите увеличенную скорость. Это автоматически отрегулирует продолжительность клипа, но вы можете отсоединить эти элементы управления и отрегулировать продолжительность вручную. Когда вы закончите, нажмите ОК.
Для этой конкретной сцены я сразу выделю оба клипа одновременно и открою Speed / Duration (Скорость/Продолжительность). Затем я немного увеличу скорость обоих клипов, доведя процент до 105 процентов. Чтобы автоматически закрыть пробелы, возникшие между этими кадрами, я активирую Ripple Edit (Монтаж со сдвигом кадров).
Я могу применить изменения скорости / длительности к нескольким клипам одновременно и даже переключаться между тремя различными режимами интерполяции времени. Выборка кадров будет повторять или удалять кадры по мере необходимости для заполнения пустот между кадрами, Frame Blending (Наложение кадров) сгладит движение между повторяющимися кадрами, а Optical Flow (Оптический поток) создаст новые кадры. Эти параметры важны, если вы замедляете отснятый материал, так как он может запинатся.
Функция Ripple Edit (Монтаж со сдвигом кадров) автоматически закрывает промежутки после применения эффекта. И, опять же, новый процент скорости будет отражен на ярлыках клипов и подсказках на шкале времени.
Инструмент Rate Stretch Tool (Растягивание по скорости).
Вы также можете использовать инструмент Rate Stretch Tool Rate Stretch Tool (Растягивание по скорости) для изменения скорости и продолжительности клипов в Premiere Pro, что позволяет пользователям вручную ускорять клипы с помощью обрезки на шкале времени. Этот инструмент скрыт под инструментами редактирования Ripple (Монтаж со сдвигом) и Rolling (Монтаж с совмещением). Используйте горячую клавишу R для активации.
Есть несколько способов, как ускорить видео в adobe premiere pro или замедлить его. Все они начинаются одинаково, вне зависимости от того, какой эффект вам нужен.
Способ № 1. Настройки скорости и продолжительности
- Загрузите файл, с которым собираетесь работать, и выберите его на панели Timeline.
- Пройдите путь Clip-Speed/Duration, или если видеоредактор на русском языке — Клип-Скорость/Продолжительность. Вызвать это окно можно комбинацией Ctrl+R.
- В поле Speed (в рус. Скорость) пропишите необходимую темп, с которым должна воспроизводиться запись. Изначально он равняется 100 %. Соответственно, чтобы замедлить видео вы можете поставить значение 50, а ускорить — 200.
- Поле Duration (в рус. Длительность) необходимо для определения продолжительности клипа. К примеру, при его воспроизведении в обычном режиме длительность составляет 10 секунд. Если увеличить значение до 20 секунд, вы замедлите ролик в 2 раза, и наоборот.
- Значения Speed и Duration (в рус. Скорость и Продолжительность) изначально связаны между собой. Для корректного рендеринга при изменении одного показателя, второй не должен меняться.
Чтобы убрать связь, нажмите на значок
цепочки рядом с ними.
- Не забудьте о трех чек-боксах, расположенных в нижней части окна Speed/Duration.
Если вы хотите, чтобы записанное воспроизводилось задом-наперед, поставьте галочку рядом с Reverse Speed (в рус. Скорость инверсии).
Для изменения изображения без потери качества звука кликните рядом с Maintain Audio Pitch (в рус. Поддержавать высоту аудио).
Но если вы хотите, чтобы участники клипа разговаривали как мультяшные герои, пропустите этот чек-бокс.
Меняете длительность не в отдельном клипе, а в середине видеоряда? Нажмите на Ripple Edit, Shifting Trailing Clips (в рус. Монтаж со сдвигом, сдвиг конечных клипов), чтобы остальное изображение правильно сдвинулось дальше, или наоборот, подтянулось.
Способ № 2. Инструмент Rate Stretch (Растяжение/Сжатие)
Эта инструкция проще предыдущей: из нее вы узнаете, как работать со скоростью материала непосредственно на главной панели. Приступим:
- Выберите инструмент Rate Stretch (в рус. Растягивание по скорости).
Вы его найдете на панели Tools ,рядом с остальными инструментами.
- Поставьте курсор с краю клипа в конце и, удерживая левую кнопку мыши, растяните или сожмите ролик насколько вам нужно. Вот и проделана вся работа. Как вы могли и сами догадаться, при сжатии скорость записи будет увеличена, а при растяжении — замедлена.
В принципе всё, я думаю написал понятно.
Станьте настоящим режиссером, сидя дома. Ведь помимо ускорения и замедления клипов, программа Adobe Premiere Pro позволяет корректировать цвета, обрезать и склеивать «картинку», добавлять титры и т. д.
