Here a 240fps frame rate will play back at 10% of the original speed – so with a 10x slow motion effectĪ HFR mode might be a codec such as 4K 50p that you intend to play back at 25p for a 2x slow motion effect. You’ll see whether the option is switched on or not, and you’ll also see the details of the options you have selected and the effect they will have on your footage. This is the Variable Frame Rate control panel. All of the current Lumix G and S series cameras, and many older models, allow us to create at least 2x slow motion through their 48, 50 or 60fps recording settings. The key to whether we can create slow motion video that looks good is to find a camera that will allow us to record at these higher frame rates.įortunately the Lumix series offers users a very good choice of cameras that can record high-frame-rate video of the sort that’s ideal for playing back at lower rates for fabulous-looking slow motion. To get successful 2x slow motion that plays smoothly we need to set the camera to record at 50fps. ![]() To achieve smooth motion we still need to play our footage back at 25fps, so to get a slow motion effect we need to record at a higher frame rate in-camera so we can slow it down afterwards. Footage played at 12.5fps might look like an old Charlie Chaplin film or a flip-book. The problem with this situation is that footage played at 12.5fps will look jumpy because it doesn’t have the enough pictures to display in each second to create motion that looks smooth to our eyes. The maths are pretty simple – 25/12.5=2, so with this scenario we’ll have 2x slow motion. If you play it back at 12.5fps the clip will last 10 seconds and the motion will be slowed down to half the speed of real life. If you play that same footage back at 50fps the clip will only play for 2.5 seconds and the motion will occur at twice the speed it did in real life – everything will be sped-up. If you record a 5-second clip at 25fps and play it back at 25fps it will last 5 seconds and any motion in the scene will look normal. As we are in the UK, and our region uses the PAL standard, I’ll take 25fps as my base for examples in this piece, but it isn’t hard to convert that to 24fps or 30fps. The exact frame rate you choose will depend on where you will show your film 24fps for cinema, 25fps for TV in PAL regions or 30fps for TV in NTSC regions – though any of those will look fine on the Internet. ![]() Long ago it was agreed that this many frames in every second of footage were required to make motion in a film appear natural on-screen. ![]() ![]() For each second of action the camera records 24, 25 or 30 frames video. Most video is recorded at 24fps, 25fps or 30 frames per second. If you just slow down regular footage however your final video will be a jerky and unattractive, so we need to find a way to achieve that slow motion effect but with beautifully smooth-looking movement that looks effortlessly natural. This stretches time, making things take longer to happen on the screen than they did in real life. Slow motion video is, in its simplest form, just video footage shown at a slower rate than it was recorded. And, with a romantic backing track, the waves breaking gently on the shore as the happy couple stroll along the sunset beach transport us, and them, to another dimension. In wildlife documentaries slow motion footage allows us to see every detail as the lizard’s tongue lashes out for the fly, but in real-time it all happens in such a flash we’re as oblivious as the fly about what’s happening. We see a lot of slow motion video on TV, in the cinema and in online films because showing the world slowed-down not only helps to reveal the details of how high-speed events take place, but it can also support the creation of atmosphere while injecting a little more drama into every day occurrences.
