![]() Download and install Gemini 2 on your Mac.It’s so simple and straightforward, all you need to do is follow these three steps: Thankfully, you can use an app like Gemini 2 to scan your entire hard drive for duplicate videos and help you quickly remove them. Those duplicates don’t do anything except clutter your hard drive and waste space. It’s easy to accidentally end up with duplicate videos on your Mac. It's all about finding how much you can compress it to reduce the file size without noticing that the video is actually of lower quality. Because even if you compress a video ever so slightly, there will still be some quality loss. Is it possible to compress videos without visible quality loss?Ĭompressing videos on Mac is a balancing act. Whatever data can be stripped out of each frame is taken away, making the overall file smaller. Since a video is just a series of photos rapidly playing in succession, the process is actually very similar to compressing an image. What is compression and how does it work?īefore you just compress all of your videos, it's important to understand what it is and what happens to a video when it's compressed. And with no shortage of options, figuring out where to start with it all can feel overwhelming.īut don't worry, if you keep reading, this article will explain video compression and how to compress a video on a Mac. ![]() So, whether you're running out of space on your hard drive or you're trying to send a movie that's too large, compressing videos is a great way to reduce their file size. It's not a surprise that the largest files on your Mac are probably your videos. It’s an app that will scan your Mac for duplicate files and then lets you quickly delete them just by clicking the Smart Cleanup button. For now, it suffices to know it can be managed several ways, including with a single unified repository, multiple branches, subrepositories, or even multiple overlapping repositories.Here’s a tip for you: download Gemini 2. (How to segment development and deployment assets in that case is a separate can of worms. Indeed, it may be required, say if you lack robust build / post-processing opportunities on the servers / services to which you deploy. If you're using Git as a deployment engine, storing minified/optimized assets in Git may switch from "no!" to desirable. In this role, Git's ability to efficiently determine "what files changed?" is as important as its more granular ability to determine "what changed within each file?" If Git has to do a nearly full file copy for minified/optimized assets, that takes a little longer than it otherwise would, but no big deal since it's still doing excellent work helping avoiding a copy of "every file in the project" on each deploy cycle. A number of cloud vendors and DevOps teams use Git and similar not just to track development updates, but also to actively deploy their applications and assets to test and production servers. There is a major exception to this, however: DevOps / cloud deployments. Your disks may be large enough and your networks fast enough that isn't a massive concern, especially if there were a value to storing the minified/optimized assets twice-though based on point 1, the extra copies may be just 100% pointless bloat. Your repositories will grow more quickly as a result. As a result, the diff-algorithm will often believe it sees almost an entirely different file every time. Their output is perturbable small input changes can lead to major changes in output. ![]() Many parts of the Web build process-tools like Babel, UglifyJS, Browserify, Less, and Sass/SCSS-aggressively transform assets. The most trivial example is removing line breaks and other whitespace the resulting asset is often just one long line. But the transformations made in the minify/optimize step often remove the similarities and waypoints the diff/delta algorithms use. To do that, they "diff" the latest file with the previous version, and and use these deltas to avoid storing a complete copy of every version of the file. Source control systems work by recognizing the changes ("deltas") between different versions of each file stored. It violates the "don't repeat yourself" (aka DRY) principle.Ī less philosophic but more practical reason is that minified / optimized assets have very poor compressibility when stored in Git. Storing compressed assets is basically storing the same logical content twice. ![]() They can be almost trivially regenerated by your build process on the fly from source code. Why not store minified or compressed assets in source control system like Git? Indeed, his "no" could be stated somewhat more emphatically. For cloud and DevOps deployments, however, it's often convenient, or even required. "It depends." For normal development tracking, no.
