There are many open source tools out there for editing, tweaking, and converting multimedia into exactly what you need. Tools like Audacity or Handbrake are fantastic, but sometimes you just want to change a file from one format into another quickly. Enter FFmpeg.

FFmpeg is a collection of different projects for handling multimedia files. It's often used behind the scenes in many other media-related projects. Despite its name, it has nothing to do with the Moving Picture Experts Group or the myriad multimedia formats it has created.
In this article I'll be using FFmpeg through the command-line tool ffmpeg, which is only a single, small piece of the FFmpeg project. It's available on many different operating systems and is included in some operating systems by default. It can be downloaded from the FFmpeg website or through most package managers.
FFmpeg is a powerful tool that can do almost anything you can imagine with multimedia files. In this article, we are interested in using it to convert files, so we won't be taking a deep dive into its entire feature set. Before we look at using FFmpeg, first we need to take a quick look at what a media file exactly is.
At a very high-level view, a media file is broken up into a container and its streams. The streams include the actual AV components, such as a movie's audio or video, and are encoded using a particular media encoding, or codec. Each codec has its own properties, strengths, and weaknesses. For example, the FLAC codec is good for high-quality lossless audio, whereas Vorbis is designed to compete with MP3 in file size while offering better audio quality. This means a FLAC-formatted file will be much larger than a Vorbis audio stream but should sound better. Neither is inherently better than the other, as each is trying to do different things.
This is an abstract representation of media files and skips over a lot of the differences between containers. Many require certain streams and metadata or put restrictions on the codecs or contents allowed. This explanation is enough to get you through this article. To learn more, click on the links above.
This command takes an MP3 file called input.mp3 and converts it into an OGG file called output.ogg. From FFmpeg's point of view, this means converting the MP3 audio stream into a Vorbis audio stream and wrapping this stream into an OGG container. You didn't have to specify stream or container types, because FFmpeg figured it out for you.
More often than you'd like, the file you have is partially correct with only a single stream in the wrong format. It can be very time consuming to re-encode the correct stream. FFmpeg can help with this situation:
The simplest method is to change the bitrate, which may or may not result in a different quality. Humans' ability to see and hear isn't as clean and clear cut as we'd like to think. Sometimes changing bitrates makes a huge difference to the subjective quality. Other times it might do nothing but change the file size. Sometimes it's very difficult to tell what will happen without trying it out.
Changing these settings is most effective for quickly reducing a high-quality stream to make a smaller file size. Adjusting the size of your video can't improve the quality, but can make it fit better onto a tablet instead of your TV. Changing the size of a 640x480 video to 4K will not improve it.
Changing the quality of your files is a very subjective matter, which means there is no one way that will work every time. The best method is to make some changes and test whether it looks or sounds better to you.
Often you have a file that is almost perfect, and you just need to trim a few parts off. This can be done more easily with a tool that shows you what you're changing, but if you know exactly where you want it trimmed, it is very easy to do it in FFmpeg:
This command creates a GIF of the same dimensions as the input file. This is often a bad idea, as GIFs don't compress well relative to other video formats (in my experience a GIF will be around eight times larger than the source video). It may be helpful to use the -s option to resize your GIF to something a bit smaller, especially if the input source is quite large, such as HD video.
Youtube-dl has several options for controlling the quality and format of the downloaded video, but I find it easier to use the command above. It downloads the highest quality audio and video into a single file, then I use FFmpeg to convert them into the format I want.
You can export photos so that you can import them and work with them in other apps. The easiest way to export photos is to drag them to a location in the Finder. You can also use the Export command, which allows you to specify file format, filename, and subfolder organization settings. You can choose the size and format for the exported photos. You can also export a Live Photo as a still image.
For example, if you export photos from several different days, you can have Photos export each day as a subfolder named after the day. Choose None to export the photos as individual files without subfolders.
You can export videos so that you can share them or work with them in other apps. When you export a video, you can choose the movie quality and whether metadata such as a title or caption is included with the exported file.
For example, if you export videos from several different days, you can have Photos export each day as a subfolder named after the day. Choose None to export the videos as individual files without subfolders.
To save a call on desktop, go to your chat and click the More options button, and then select Save to Downloads to save to your downloads folder. You can also select Save as and navigate to the folder where you want it saved. The recording will be saved as an MP4 file.
In the top-right corner of any App Store Connect page, click your name, then select Edit Profile. Make sure you are viewing the account associated with the team you want to leave. If not, switch to the correct account.
If applicable, determine if the user should have access to additional permissions such as Access to Reports, Certificates, Identifiers & Profiles on the Apple Developer website, or Create Apps. Note that certain permissions will make all app information visible to the user and therefore, they cannot have their app access limited.
In-app purchase keys are private and can only be downloaded once. After downloading the key, store it in a safe place. Remember to revoke a key immediately if it becomes lost or compromised and ensure that offers using this key are updated.
If your app distributes Wallet passes that require ongoing updates from your app or web service, the passes will eventually need to be reissued using a new identifier after transfer is complete so they can be signed with certificates issued from your Apple Developer account. To minimize user confusion and avoid interruption, we recommend providing a message in your app to let users know that their previously issued pass will become inactive and to download a new pass from your app or web service.
If your app uses iCloud Key-Value Storage (KVS), the full KVS value will be embedded in any new provisioning profiles you create for the transferred app. Update your entitlements plist with the full KVS value in your provisioning profile.
The device type is the target device for the variant. Universal refers to the variant that runs on all supported operating systems and target devices that are delivered to customers running iOS 8 and earlier, apps purchased in volume through Apple School Manager and Apple Business Manager or through Mobile Device Management (MDM), or apps downloaded using iTunes 12.6 or earlier.
If any of the device variant sizes exceed the 200 MB over-the-air download limit, a yellow warning appears next to the build string in the Builds table and next to the variant size in the App Store File Sizes table. Click the warning icon to read the full warning. Apple will also send you an email with this information.
Testers install the free TestFlight app on their devices. Then they use their invitation email or a public link to accept invitations, install your app, send feedback, and get updates. Testers download and install thinned variants of your app.
If you have builds available for testing, the users you selected will receive an email inviting them to test the app. The users will be directed to accept the invitation using the TestFlight app on their device or via a redemption code. Internal testers will be able to download and test all builds for 90 days.
Before releasing your app on the App Store for the first time, you can choose to offer it for pre-order. Customers can view your product page and order your app before it's released for download. Once your app is released, customers are notified and your app automatically download on the device on which they made the pre-order. It will also download on their other devices if they turned on automatic downloads . For paid apps, customers are charged before download.
While your app is available for pre-order, you can update your app by creating and submitting a new version. The new version must be approved before it can be published for pre-order on the App Store, so be sure to follow the App Review Guidelines. If you submit a version update during the pre-order period, customers will receive the latest version published to the App Store once your app is released for download.
Once your app is approved and you're ready to make it available for pre-order, return to Pricing and Availability. Confirm the date your app will be released for download, and click Release as Pre-Order on the top right.
Your app will be released to the App Store. Customers who pre-ordered your app will be notified and your app will automatically download to their device. For paid apps, customers will be charged before download. 041b061a72
