#Imazing heic converter com surrogate issue upgrade#I mean, all my images are 8-bit anyway, so it's kinda moot, but something to at least confirm what mode it's running in would be nice, even if it just says "to use 16-bit color you must upgrade to iMazing " when you try to flip the switch.This post is sponsored by Olay but all thoughts and opinions are my own. You mean >8-bit color depth or something else? Because that was one of the things that kinda annoyed me with your converter, was that my options didn't include any control for bit-depth. We added support for Wide Gamut Color recently Not sure how ffmpeg handles colour profiles HEIC has been around for longer than most folks realize, and it's not like people can't buy the specs for their own decoders. With several dozen HEIC images to convert (and potentially several dozen more on the way) it just wasn't time-effective to do them one at a time. Running macOS 10.11.6, and the problem I ran into was if I dump a pile of HEIC images into the converter it would only select one of the images, instead of queing them up for batch processing. #Imazing heic converter com surrogate issue update#Upgrading your copy from then on out is brew update followed by brew upgrade (or brew update & brew upgrade, & meaning "run this command after the previous finishes").Ĭould you please let us know what precise issue you had? Also, Windows or macOS? #Imazing heic converter com surrogate issue install#You first need to install XCode, install Homebrew, and then it's a simple brew update and brew install ffmpeg. OR on OS X macOS you can follow my preferable method, using Homebrew, a package manager. You can then either just drag the executable file into your Terminal or PowerShell and enter the rest of the command that way, or you can "install" it so you can invoke it from anywhere.įor Windows follow these instructions, I've done this at home and can confirm it works.įor OS X macOS you run sudo cp /usr/local/bin/ and you'll be prompted for your password. #Imazing heic converter com surrogate issue how to#If you don't know how to get started with ffmpeg, you can download binaries from their website. If you do wind up with >8-bit HEIC images and you want to preserve that, change rgb24 to rgb48.Īll files were tested in Preview (except ProRes and DNxHD), and opened fine. ![]() ![]() You also might have to specify a frame rate with -r. To set the ProRes flavor you use -profile:v and specify 0-4 (0=Proxy, 4=4444). And then I just batched it: for f in *.heic do ffmpeg -i "$f" -c:v tiff -pix_fmt rgb24 "$mxf" for DNxHD), though for DNxHD you'd obviously have to play around with the resizing commands to conform to an appropriate resolution. ![]() Lo and behold, it worked! It produced a 16-bit TIFF file! Once again the magic swiss army knife that is ffmpeg Of course, after that I realized the photos were all 8-bit. ffmpeg can handle H.265, so maybe it could handle HEIC!" ffmpeg -i (file).heic -c:v tiff -pix_fmt rgb48 (output).tiff Then I thought, "well wait a minute, HEIC is basically just a single frame of H.265. And for anyone who is going to have to deal with anything that ever comes out of an iPhone, which we all almost inevitably have to, we need some way to deal with it, especially those of us who can't upgrade to High Sierra because it'll break stuff, and those of us in the Windows world.įirst tool I came across was the iMazing HEIC Image Converter, recommended by a few websites, but I had issues getting it to handle batches of photos. So with the advent of the new iPhones Apple has, again, decided to make our lives more complicated by introducing a new (well, not that new, but mass-market new) image format: HEIC. ![]()
