Converting JPEG to HEIF and why it’s a bad idea

Must you exchange your current iPhoto Library to use new report codecs to save area?

Probably the most new options of macOS 10.13 Top Sierra and iOS 11 is the addition of 2 new media codecs:

• Top-Potency Symbol Record Structure (HEIF) for pictures.

• Top-Potency Video Coding (HEVC), often referred to as H.265, for movies.

HEIF is meant to be a successor to JPEG, whilst HEVC will supplant H.264. Either one of those new codecs are business requirements and despite the fact that they might not be in large use at the present time, they'll be actual quickly now for 3 large causes:

  1. Upload anything else new to iOS and it temporarily will get disseminated to tens of thousands and thousands of iOS units. Notice Apple's feedback about the way it become the most important augmented fact platform in a single day as soon as AR generation shipped as a part of iOS 11. All of us all at once had the risk to experience a T-Rex galavanting unencumbered round a basketball court docket.
  2. The 2 new codecs have significantly better compression algorithms than JPEG and H.264, so pictures and movies encoded with those codecs will take in a lot much less area on iCloud Photograph Library and on flash-memory constrained units like iPhones and iPads.
  3. Although the brand new report codecs compress pictures and movies to a a lot better level, there's no lack of visible high quality.

So... higher high quality and dramatically smaller report sizes? Bought! The place do I signal?

HEIF and HEVC are the way forward for virtual pictures and movies

The excellent news is that any pictures or movies shot with fresh iPhones (the 7 collection or later) and iPads (the 10.5-inch and 2d era 12.9-inch Professional fashions) which might be operating iOS 11 will use those new media codecs by way of default.

You've got the choice of continuous to use JPEG and H.264 codecs on those units if you need. However as a result of Apple has already inbuilt a mechanism to convert a HEIF report to JPEG when it's shared (for instance, via e-mail or Messages) there is no actual excellent explanation why to use the fewer environment friendly JPEG structure. It's a little dicier when it comes to sharing H.265 movies on some older units, however the simple answer is to improve to macOS Top Sierra and iOS 11 and work with the video in its new structure.

So we now have a rosy long term forward, with the power to stretch our garage a bit farther with out an build up in value, leaving the entire more space for AR T-Rexes to fill.

All of this, after all, begs the query: OK, so how do I convert all my outdated JPEGs to HEIF and H.264 movies to H.265? If saving area and not using a lack of high quality is a excellent idea for brand new pictures and video, is not it an excellent higher idea for the 1000's of pictures and movies I have already got which might be sucking up treasured space for storing?

Converting might be superior, however at this time, it's now not

The web is filled with web sites that provide to convert a report in line with one structure into any other. You'll in finding them with a easy seek. Listed below are two that I got here throughout, either one of which provide the power to convert your JPEGs to HEIF and H.264 movies to H.265.

And there are apps that'll do likewise. However as a result of HEIF and HVEC are solely now rising as long term mainstream codecs, many of those web sites and apps both can not care for the brand new codecs in any respect, or have some unfavorable byproducts, akin to getting rid of EXIF information (this is, information about a , akin to location and digital camera settings) all over the conversion procedure.

One site, JPEGtoHEIF lists step by step directions for changing a JPEG to a HEIF, however it's now not for the faint of middle. If you already know phrases like Homebrew, Git, cmake, and FFMPEG, you will have to give it a check out and inform me the way it labored out for you. However, if the ones sideloading methods kinda provide the shakes, do like I did and take a move on that one.

However, I am the curious kind. So I did a little digging for some Mac apps that care for conversion whilst additionally safely cover the command line from me.

How I transformed H.264 to H.265 and what my cat considered the entire procedure

Handbrake, a unfastened, open-source video transcoder, can convert H.264 information into H.265 structure. I examined it with — what else? — a video of my cat enjoying with the trade finish of a laser pointer. The H.264 video used to be about 16 seconds lengthy, 21.4 MB in dimension, and had a .m4v report extension. It took simply a minute or so for Handbrake to convert it to the H.265 structure. After conversion, the report used to be 5.4 MB in dimension (a 75% aid in dimension when compared to the unique) and had a .mp4 report extension.

Nice! So it labored... however now not actually.

The H.264 report would now not open in QuickTime Participant and solely the audio performed after I opened it with iTunes. So I attempted it the use of VLC, a unfastened video participant that may care for a lot of various codecs. To my eyes, there used to be no discernable distinction in high quality when compared to the H.264 model (and the cat did not corral the laser in both model of the video, I do know you sought after to know that).

When it got here time to drag the H.265 video into the Pictures app so I may test at the standing of the EXIF information, Pictures would not take it. Even sneakily converting the report's extension to .m4v did not paintings. I used a couple of different apps to check out to dig out the EXIF information to no avail.

So, I re-transcoded it the use of Handbrake again into H.264 structure. Once more, it took simply a minute or so and created a report that, at 6.5 MB in dimension, used to be relatively better than the H.265 model. I used to be ready to effectively import it into Pictures with a drag and drop (even supposing it retained its .mp4 report extension), however the EXIM information — particularly, the date and location of the video and the digital camera data — used to be lacking.

The mess I made changing a JPEG picture to HEIF

Image2HEIF prices a couple of dollars at the Mac App Retailer and will convert photographs in more than a few codecs (BMP, GIF, JP2, JPG, and PNG) into HEIF.

The app description makes it transparent that "authentic EXIF/metadata isn't transferred to transformed .heic symbol". So no necessary data is stored like date, location, or digital camera settings. As well as, whilst I effectively transformed 3 other JPEG information and noticed no discernible drop-off in high quality, the report dimension used to be now not diminished by way of a vital quantity. In reality, in two of the 3 instances, the HEIC information have been relatively better than their JPEG originals.

Only for amusing, I transformed a 3 MB JPEG report into a 20.9 MB PNG structure the use of Preview's export command. Then I ran the PNG report via Image2HEIF and it produced a 2.9 MB HEIF report. So, , what is the level?

To make issues much more tough, the entire HEIF information have been locked after I opened them with Preview, and after I attempted to release them, I used to be knowledgeable that the report did not beef up enhancing, so I used to be introduced the risk to replica it into a TIFF structure to edit. I may, on the other hand, simply import and edit them in Pictures.

Forestall to suppose whether or not you will have to

Within the film Jurassic Park, the mathematician performed by way of Jeff Goldblum has a relatively shut come across with a T-Rex (of the non-AR selection), introduced again to existence via complex genetic engineering. He delivers a very succinct ethics lecture to the undertaking chief and his quest to deliver dinosaurs again to existence: "Your scientists have been so preoccupied with whether or not or now not they might, they did not prevent to suppose in the event that they will have to."

I am not pronouncing that a JPEG transformed to HEIF goes to rampage via your community, drink the entire water for your swimming pool, tear the roof off of your own home, and swallow you complete. However it might do one thing that you may now not like. At the perfect, it's a time-consuming procedure that does not actually cut back the report dimension that a lot.

In accordance with my restricted checking out, it's almost definitely now not well worth the effort for many people to convert a bunch of movies and pictures to the brand new HEVC and HEIF codecs simply to avoid wasting space for storing. A large number of time and effort can be concerned to make the conversions — now not to point out having to recreate misplaced EXIM information. For me, with the present stage of generation to be had, it's now not well worth the tradeoff.

One day, the codecs will turn out to be extra mainstream and Apple will most probably construct one thing into Pictures and/or iCloud that can lend a hand care for this. In interim, I am going to persist with what I have were given.

Any questions?
