One application that you can install on your iPhone is Video Compress-Shrink vids. All-in One Video Compressor to Resize Video Resolution, Size, Bitrate, etc. After that, we will give the All-in-one video compressor software for Phone that you can install on your PC. In this article, we will discuss the best video compressor apps for Android and iPhone. To utilize your phone storage and ensure you have many videos, you will have to compress video on Android or iPhone. However, with large and high-quality files, most of your local storage on Android or iPhone will be used up. Some people prefer to store movies on their phone and watch them when they are traveling. The only time lossless compression is used, is in stuff like 7zip, where you must maintain everything perfectly, or as a source file.- 'What is the best app compressor so that I can free up space on my phone?' This is done with lossy compression, usually via DXT1, but BC7 is seen too on pc, ETC2 and ASTC are seen on mobile. Game textures must be compressed or they will chew up your vram. You lose color precision due to it being lower precision over a larger spectrum of color, then converted back to rgb. Actually, the video existing YCBCR, by far the most popular color space is in itself lossy. Usually ultra high bitrate h.264 is used due to its fast encode, and then youtube turns it into VP9. You see pretty much nobody recording in huffyuv and flac. High bitrate is used for audio and video for even source files. JPG or more effectively WEBP are used in web to shrink images, but also are commonly found in desktop applications too. Lossy formats are used almost always in some way or form, except as a source file and even then there are are exceptions. In fact most people mistake lossy and lossless. You are the only person i have heard of that says compression is purely lossless. Lossy algorithms have different purpose than lossless ones and I think lossy algorithms is best suited for web, when quality is not so important and we only want a playable content but for offline using lossy algorithms over and over for re-encoding videos really doesn't make sense. It's like we're working on a JPEG picture to make many edits but instead of using a lossless algorithm like PNG or PSD (at least until all of our changes done), we're saving it with same lossy algorithm over and over and over and finally we have a way more crappy output than our original JPG. So that's why I said there's no compression for already compressed algorithms like H264, because those algorithms already removed so many stuff from original content (maybe bluerays) that created from, then removing so much more for saving some space with encoding it again with same lossy algorithm, doesn't really make sense unless data is not so important. think of it as a suitcase, when our stuff doesn't fit our suitcase, first we try different methods to put all of them together and if it finally fits, we can call it a compression but when there's no way to fit our stuff in that suitcase even with different puzzling solutions then we think about removing some stuff that we wanted at first but now we can't have a choice. You're right about lossy and lossless algorithms but removing stuff from something is not what most people think of compression. Just be careful about KBs or MBs in Bitrate, if Bitrate is in MB but your encoder software only accept KB then you need to convert MB to KB before doing divide thing.Īs encoder software, I recommend Avidemux or Handbrake but if you want something more easy to use you can use Format Factory too but beware it's have bundles in its installation that you have be careful to doesn't agree to install. This way you can shrink file in a good amount of size. I say divide Bitrate by 2 because you're going to get half of resolution (720p instead of 1080p) then you'll need only half of video Bitrate too. You can lower resolution to 720p but first I recommend you to install MediaInfo software to see actual Bitrate of your video with it, then you can divide it by 2 in a calculator then use it as constant Bitrate in any encoder software. The only way you can shrink a video file is by actually decreasing its quality or removing some extra tracks like audio in other languages if it had in it. There's no such thing as video compressor because almost all of common video formats are already highly compressed codecs like H264 that is used mostly in MP4 and MKVs.
