What is Speed Ramping and how do I do it?

Learn what speed ramping is and how you can easily use it to augment your footage in our quick beginner’s guide

Put simply, speed ramping or time remapping is the art of slowing down and speeding up your footage in order to produce dramatic and creative effects.

It’s a technique popularly used in Hollywood, especially notable in the 1999 film The Matrix directed by the Wachowskis and also used to stylish effect in Zack Snyder’s 2006 film 300.

However, you don’t need a multi-million-dollar Hollywood budget to include speed ramping in your own footage. We’ve put together a quick video tutorial to demonstrate how a few quick adjustments in your editing software are all you need to get started – click above to watch.

One thing you will need is a camera capable of shooting at a high frame rate. About 50fps is the lowest our expert recommends you push it, as anything below that is going to look juddery.

Fear not though, as this doesn’t have to be a major investment. The Canon EOS 600D, for instance, is perfectly up to the job, even though it’s four years old now. You can pick one up for between £200 and £300 these days, and if you’re willing to go second hand you can get it even cheaper.

Of course, for the optimal performance you’d want to plump for something like a Canon C100 Mark II, however we’re assuming you don’t have nearly £4,000 lying around to spare on one (if you do then go for it).

Once you’ve got your footage, there are a number of options for how you want to implement the speed ramping effect in post – we outline two of the easiest in the video above.

Once you’ve gotten the hang of your preferred method then you can start to do more creative things and push it further: for instance try duplicating your scene and playing it backwards, or pushing your speed right up to 2,000% for a brief burst of frenetic action.

Speed Ramp: How to Slow Down or Speed Up Your Video

When we do something with the shot’s speed, slow it down or speed it up, we are doing time remapping, also known as speed ramping.

What is speed ramping

Slow down the scene a bit, and it will become more dramatic. You let the viewers see the smallest details frame by frame (provided your film is at least 60fps and you used high shutter speed when recording it). Also, the change of speed can indicate that this very piece is so important that one must be all eyes not to miss anything. And one will be!

Speed up the footage and you will get action, drive, or you can use it as a cool transition shot. And what about becoming a star of your own clip a la the silent movie?

Experiment with different speed options and find the one that delivers your message most effectively. Luckily you do not need to download a professional software for that, as there is an online tool that allows you to easily change speed. Let’s see how it works.

Add your clip

Open any browser and go to Clideo’s Online Time Remapping tool. You can upload your movie from your device, whether it is a computer, tablet, or phone. Just hit the big blue “Choose file” button. Any format will work perfectly.

Online videos can also be added easily. Under the drop-down arrow, select Google Drive or Dropbox. A URL will also work great. Just remember, to keep it all free, your file should be up to 500 MB.

Change the speed of your video

In the right pane, you will be able to speed up or slow down. Use the slider to manually adjust the speed in small increments of 0.05x. Your maximum speed could be 4x, which is 4 times faster than the original video. Or just hit one of the predefined speed buttons, say, “2x”, to speed everything up, both your movie and your workflow.

Pay attention to the preview area — all your changes are instantly displayed over there. No need to wait for hours and guess what will be the result.In the bottom left panel, you will see the actual final duration of your film.

In addition to that, if your original clip is not in the right format, call the drop-down menu to select the one you need. When your initial file type is fine, don’t do anything.

By default, the film will be muted, so that you could later add any dramatic audio. To keep the sound, uncheck the “Mute video” box.

So when everything is perfectly adjusted, hit the “Export” button in the bottom right corner. The processing won’t take long.

Get your Oscar

When done, the final preview of your remapped video will be displayed. Double-check that it has the wow effect you planned.

Click “Download” to save the new clip back to your device, or, under the drop-down arrow, select Dropbox or Google Drive to have your masterpiece stored over there.

The “Edit” button will take you to the previous screen to try different settings. And if you have other videos to speed ramp, click the “Start over” link.

What is speed ramp

Техника Speed Ramping широко распространена в современном кинопроизводстве, но это не означает, что он должен использоваться во всех случаях по умолчанию, как и любой другой метод монтажа, особенно когда дело доходит до короткометражных или художественных фильмов. Итак, давайте разбираться где и когда наиболее уместна эта популярная техника редактирования видео.

Конечно, Speed Ramping может отлично выглядеть в спортивных видеороликах, но если это не мотивировано и не имеет отношения к рассказываемой истории и сюжету, это не принесет вам или вашему фильму никаких дополнительных дивидендов.

Speed Ramping является отличным способом привлечь внимание зрителя к определенному моменту в вашем видеоролике, а также может быть дополнительным и эффективным способом редактирования видео, который добавляет больше динамики вашим кадрам. В видео ниже Joe Simon раскрывает основы этой техники и поделится некоторыми советами о том, как использовать ее в своих видеопоектах.

Вкратце, Speed Ramping отлично подходит для создания плавных переходов в замедленном движении, но он также может эффектно продвигать героев и персонажей через сюжетные линии в разных пространствах или времени. Лучший способ достичь отличных результатов при Speed Ramping — использовать камеру, которая может снимать гораздо более высокую частоту кадров, чем стандартная 24p. Чем выше частота кадров, тем более впечатляющим и драматичным будет эффект.

Другой важной настройкой, которую следует учитывать при съемке замедленного движения, является выдержка камеры. Как правило, вы должны удвоить скорость затвора в зависимости от выбранной частоты кадров. Однако, имейте в виду, что это повлияет на количество света, которое достигает датчика, поэтому необходимо тщательным образом подходит к освещению при съемке. Съемка при дневном свете на открытом воздухе, как правило, не создаст проблем , однако, когда вы снимаете в студии или в месте, где есть много искусственных источников освещения, съемка с высокой частотой кадров может вызвать определенные трудности, имейте это в виду.

Что касается постпродакшна, вы можете использовать любой видеоредактор, который имеет функцию изменения скорости воспроизведения. Например, в Premiere Pro CC откройте клип, к которому требуется применить эффект, и добавьте его на таймлайн. Затем нажмите на значок fx в левом верхнем углу, перейдите к Time Remapping и выберите Speed. Оттуда вы можете легко создавать точки входа и выхода, показывающие, где вы хотите, чтобы ваш Speed Ramping начинался и заканчивался соответственно. Выбор правильного момента начала действия имеет решающее значение для достижения наибольшей эффектности.

И последнее, но не по значению, — убедитесь, что вы выбрали самый важный момент вашего видео и не переусердствовать со Speed Ramping. Используйте меньше подобных переходов, чтобы увеличить влияние каждого из них и применяйте их только в нужном месте в нужное время или когда вы точно знаете, что они служат повествованию вашей истории, а не хаотизируют ее.

How to Create a Premiere Pro Speed Ramp

In this tutorial, you’ll learn to create a beautiful speed ramp in Adobe Premiere Pro CC, from capturing the right kind of footage to advanced tips and tricks. Then, we’ll go over ideas and inspiration for when to use a speed ramp. Spoiler alert: if you edit video for any reason, a speed ramp is a great tool to have in your video editing arsenal!

What is Speed Ramping?

Speed ramping is the process of progressively changing the speed of a video clip over time. What might immediately come to mind is using this to highlight actions in sports. For instance, a clip is playing in real-time, then slows down for the duration of a jump, kick, or flip, before resuming normal speed.

While speed ramping is used a lot in sports highlights, adjusting speed can be effective for many types of footage. For instance, check out this example created using this clip of a DJ.

Basic Edits in Premiere Pro

Alright, let’s dive into creating a simple speed ramp in Premiere Pro. Start by adding the DJ clip from the above example in the timeline or whatever clip you want to add a speed ramp to .

1. Before beginning any work with speed, click and drag to increase the height of the video track in the timeline. This will ensure that you can see the speed ramp in the next steps.

If you’re working within a sequence of clips, you may also choose to drag the clip to a new track while you work as speed changes will affect the length of the clip.

2. Right-click the Fx button on the clip and choose Time Remapping > Speed. The rubber band across your clip now represents the speed of the clip (the default parameter is opacity).

3. Dragging this band up or down will change the speed of the clip. If you’re starting with a slow motion clip, drag the band up (typically to about 250%-300%) to begin with the clip at normal speed.

4. To create a speed ramp, you will need to add keyframes. Command + Click (Mac) or Control + Click (PC) the rubber band to add a keyframe. Note that keyframes will display and can be manipulated both in the Timeline and in the Effect Controls panel.

5. Add two keyframes to divide the clip into three parts. Click and drag the middle section up for fast motion, or down for slow motion.

6. At this point, when you play the clip back, you’ll notice the speed change is abrupt. The effect looks more like a cut than a ramp. Click and drag each keyframe to split it, creating a gradual speed change instead.

Note: if you need to reposition the entire keyframe Option + Drag (Mac) or Alt + Drag (PC) the keyframe. Experiment with different length speed ramps until you’re happy with the timing.

Advanced Speed Ramping Techniques

Create a Smooth Speed Ramp with Keyframe Interpolation

A speed ramp has keyframes marking a starting and ending point for the speed change, but there are a couple of ways Premiere can get the footage from point A to point B.

Keyframe interpolation is the process of filling in the values in between those two points. Simply dragging to split the keyframe like the last example creates an even speed increase between the keyframes. This is called Linear Interpolation.

To create a smoother, more natural speed ramp, use Bezier Interpolation instead. With Bezier Interpolation, the rate of the speed increase will also accelerate, creating more of a “ramp” feel.

Select a keyframe and click and drag the Bezier handles to create an S-curve shape. Adjust until you’re happy with the results.

Create a Speed Ramp Transition

Speed ramp transitions are easy and can add visual interest to many kinds of videos. This effect consists of the clip speed ramping up at the end of a clip, then into a cut.

In the second clip, the speed starts fast and ramps down to create a smooth transition. It can suggest the passage of time, a character’s disorientation, or simply add flair to a marketing video. Check out this example using this clip:

In Premiere, create a ramp up at the end of your first clip, and a ramp down at the beginning of your second clip. The speed rubber band will look like a bell curve spanning the two clips.

Understanding Frame Rates When Working With Speed

When working with video speed, it’s important to understand frame rates. Videos are typically shot and played back at 24 or 30fps. Slow motion is created by shooting at a higher frame rate, (like 60 FPS, for example) and played back at 24fps.

Time Remapping is simply the act of playing the footage back at a different frame rate than which it was shot. But what if you want to create a slow motion shot or a speed ramp like the example above and you didn’t shoot your footage at a high frame rate?

Adobe Premiere will do its best to extrapolate that missing information, but artificial slow motion typically looks a little bit choppy. So, if you’re planning to use a speed ramp to highlight action in slow motion, it’s best to begin with slow motion footage.

Getting Creative

While not every project will benefit from a speed ramp, there are quite a few use cases.

Consider tutorial videos for social media: a beauty creator might demonstrate how to curl a piece of her hair in real-time, then ramp up the speed of the same clip while she finishes the rest of her hair. In a baking how-to video, a creator could add the ingredients to the bowl, then ramp it up for the stir. The reverse can also add style: add ingredients in real-time or fast motion, but slow it down for a dramatic egg cracking.

Speed ramps have a place in narrative structure too. If a character is disoriented, for instance, speed ramping into a cut can provide a transition to evoke that feeling.

And that’s it! Creating speed ramps in Premiere Pro can add function and style to a variety of videos from narrative features to social media posts. Premiere makes it simple to create and refine speed duration right in the timeline to meet any needs.
