ContainerĪ container holds the audio and video data together in a single file. To help you understand further, let’s briefly discuss what codecs and containers are. When people talk about video format, they usually talk about the container and the codec used in its formatting. To understand video formats, two terms are crucial to its definition. What are video formats, and how do they work?īefore exploring the top 10 video formats for 2022, it’s essential to understand what video formats are and how they work. In this article, we’ll walk you through the top 10 video formats for 2020 to help you get a grasp of what each format offers.

mp4 is an ISO standard that has much wider support.Īs noted above, you have to use MPEG-TS for videos longer than 10 minutes.These formats have different features and are suitable for various purposes. The purpose of the container is to combine (interleave) the different tracks together, to store metadata, and to support seeking. The audio and video tracks go inside a container.

The iPhone 7 / 7 Plus, 6S Plus / 6S, SE all support AAC bitrates of 8 to 320 Kbps. The iPhone supports a few audio formats, but the most modern and by far most widely used is AAC. The question is about video, but that video generally has one or more audio tracks with it. Of course this is just a recommendation and YMMV. Figure 3 in that document gives a table of recommended streaming parameters:Īs you can see, Apple recommends the relatively low resolution of 768x432 as the highest recommended resolution for streaming over a cellular network. The most detailed document giving recommendations for streaming is TN2224 Best Practices for Creating and Deploying HTTP Live Streaming Media for Apple Devices. Since networks are slow and video is huge, it's typical to use lower resolutions, bitrates, and frame rates than the device's theoretical maximum. However, streaming video is a different matter. So if you're interested in playback on the phone, it doesn't make sense to send over more pixels then the screen can draw. In addition, the screen size on the 6S Plus and 7 Plus is 1920x1080. Obviously the phone can play back what it can record, so we can guess that 3840x2160 at 30 fps and 1920x1080 at 60 fps represent design limits of the phone. The only data given about hardware video support by Apple about the current generation of iPhones (SE, 6S, 6S Plus, 7, 7 Plus) is that they supportġ080p HD video recording at 30 fps or 60 fps. In talking about what video format the iPhone supports, a distinction should be made between what the hardware can support, and what the (much lower) limits are for playback when streaming over a network. This is expected to change at some point. However right now (August 2017) there is no Apple-provided library that gives access to a HEVC codec to developers. Interestingly, Apple's own Facetime uses the newer H.265 (HEVC) video codec. This is a table that lists the differences between the different profiles. More tricks give better compression, but require more CPU or dedicated hardware to decode. These profiles are basically three different levels of algorithm "tricks" used to compress the video. All modern iPhones ( 3GS and above) support the High profile. There are several different feature tiers or " profiles" available in H.264. On the iPhone, H.264 is the only game in town. ts container files (see App Store Review Guidelines rule 2.5.7).
