Step 2: You need to click the + button and then, click Movie option.In this age of HD and 4K, videos seem to keep getting bigger, but our hard drives and Internet bandwidth don't always follow suit. If you want to know how to compress a video using iMovie, read the steps given below: Step 1: Open iMovie and click projects. It helps you rapidly trim down the large video size on Mac. IMovie is an amazing video editing software that with the Mac operating system.

You can resize and reduce the resolution, or you can export it in a lower quality. Both of them can help you directly reduce video file size on iPhone iPad.If an image is too large, you can reduce its size in two ways. Happily, you can, with a little help from HandBrake вЂ“В a free app that helps you compress video without sacrificing (much of) its quality.If you have loaded off the videos to a PC or Mac, you have many solutions for.

How does video compression work?Settings like Video for YouTube allow you to select an easy profile to reduce video file size on Mac. It can be done using the versatile, built-in Preview image editing app.Before we get into how you can use HandBrake, we'll quickly review how it works its magic, and which options might best help you shrink down your videos to your satisfaction. You donвЂ™t need to use a third-party app to do this on your Mac.

Compressed video won't ever look quite as good or detailed as the uncompressed original. Throttle up your compression settings too high, and the machine gets sloppy, making the picture look blocky or less detailed (known as artifacting) or smushing a wide gradient of colors into an obvious, rainbow-y pixel smear (known as color banding.) The more compression you apply, the smaller your file, but the worse these problems get.You'll need to experiment with compression settings and methods to figure out which balance of quality and file size works best for you. By merely making a note of the pixels that stay the same, and recording only the pixels that change, video compression algorithms help fit the same video into a smaller amount of total data.VPN Deals: Lifetime license for $16, monthly plans at $1 & moreBut computers, like humans, aren't perfect. Compression uses clever math to compare each frame to the next one, looking for areas of the picture that don't change. ItвЂ™s just a video player, first and foremost.Videos consist of frames, a series of still pictures played in quick succession to create the illusion of motion.

(Big thanks to transcoding wizard Don Melton for his expertise on this next part.)To make a very, very long story short, you have two options when compressing a video with H.264 or HEVC. Again, the trade-off here boils down fairly simply: a longer wait for smaller files, or a much shorter wait for somewhat larger ones.HandBrake 1.2.0 and later enables Apple's VideoToolbox technology to dramatically speed up H.264 (and, for users of post-2017 Macs, HEVC) encoding вЂ¦ but there's a slight catch. Average bitrateOnce you've picked an algorithm, you need to decide how you're going to apply it to your video. They're generally considered comparable in quality to H.264 and HEVC, respectively. And both held up no matter what I threw at them, from animated movies to black-and-white classics to films with lots of fast action and bright colors.(Note that on some newer, faster computers, HandBrake will also offer Google's VP8 and VP9 encoders.

At the same general quality, HEVC produces smaller files than H.264.For constant-quality encoding, Handbrake can't use hardware acceleration, so it's stuck doing the math in software. Basically, the higher the bitrate, the better your video looks, and the bigger the resulting file is.At the same bitrate and file size, HEVC looks better than H.264. This results in smaller final file sizes - but while it looked pretty good to my untrained eye, the resulting picture quality might not match that of your second option.Average bitrate keeps the amount of compression within a much smaller range, hovering around a target you set. Then it adjusts how much compression it applies scene-by-scene to hit that quality mark.

HEVC, constant quality software encoding: 1.6x real time, 50.3MB (вЂ¦ no, that's not a typo. H.264, constant quality software encoding: 1x real time, 239.5MB Remember, those speeds will vary based on your own hardware вЂ“ I used a 2017 5K iMac вЂ“ but the numbers below can give you a rough idea of what to expect: (As I write this, it's not clear whether that limitation comes from the chips themselves, or the software talking to them.) You can also use average bitrate when compressing with software, but given the massive speed boost you get from VideoToolbox, that's not nearly as tempting an option.Here's a quick comparison of approximate file sizes using different compression methods, plus encode times relative to the actual length of the original clip.

On an aging 2012 Mac mini, I still got compression speeds between 0.25x and 0.33x real time. HEVC, VideoToolbox, 4000kbps: 0.4x real time, 205.6 MBGood news for folks with older hardware: You can still use VideoToolbox for H.264. H.264, VideoToolbox, 6000kbps: 0.2x real time, 286.8 MB

But before you open the downloaded file, make sure you validate its checksum. Install the appVisit HandBrake's site to download a copy. How to get started with HandBrake 1.

Find a format for your compressed videoHandBrake can open just about any video format you've got, but it will only save compressed files in two formats: MP4 or MKV.MP4 files play nicely with iTunes and QuickTime, so anyone with a Mac can view them without any additional software. You can also do this via the 'Open Source' button in the app's upper left corner, or by simply dragging a video file onto the app. Open the video you want to compressWhen you first open HandBrake, it'll prompt you to browse for the jumbo-sized video you want to diminish. Take this quick, easy step for added peace of mind.

You'll probably use its General (to create MP4 videos) and Matroska (to create MKVs) settings most often. HandBrake offers unusually helpful tooltips when you roll over each item in its interface, so I'll encourage you to explore on your own, and just cover the basics here.You'll probably first notice the preview window in the lower right, which plucks frames out of the source video to give you a rough idea of how the finished product will look.You can select MP4 or MKV from the Format pulldown menu, but especially if you're new to HandBrake, you might want to consult the Preset menu just above it. Pick your presetYou can choose between MP4 and MKV on HandBrake's Summary screen, the first one you'll see after you choose a video to compress. But iTunes and QuickTime won't play MKVs, though media servers like Plex and free players like VLC will.

(Finally, the moody, noir version of Sesame Street the world has waited forвЂ¦)Instead, head straight to the Video tab. And you can leave the stuff in Filters on autopilot, unless you really want to invert or rotate your video, or turn a color video into black & white. You can, and should, tinker with them further to your own satisfaction.You can skip the Dimensions tab вЂ” HandBrake's good at figuring out the resolution of your original image, and you probably don't want to mess with that. ( Very Fast probably won't yield good results, Fast should be, eh, decent, and HQ and Super HQ offer the best quality, and probably the largest file sizes.Presets load a bunch of settings that will likely approximate what you want. If you know what you want to do with the final video вЂ“ say, send it to someone over Gmail or upload it to YouTube вЂ“ or what specific kind of device you'd like it to play on, these videos can make configuring HandBrake a lot easier for you.Otherwise, look through the General or Matroska sections, and find a setting that matches the resolution (most likely 480p, 720p, or 1080p) of your source video, and your desired quality.

It'll offer you the different compression algorithms we discussed above, including H.264 and H.265 (aka HEVC).
