海外TECH	Engadget	The Disney+ password-sharing crackdown starts 'in earnest' in September	https://www.engadget.com/entertainment/streaming/the-disney-password-sharing-crackdown-starts-in-earnest-in-september-184122554.html?src=rss	A few months back Disney promised to further crack down on password sharing or the practice of multiple households using the same account for a streaming service That s set to come into effect in the very near future for many more Disney users meaning that account sharers will have to pay extra or have separate subscriptions to keep using the service Disney started targeting account sharing in Canada late last year and in June in select other countries It s about to expand those efforts in the coming weeks Referring to the streaming division we need to basically make it a higher return a higher margin business and a more successful business Disney CEO Bob Iger said on an earnings call with investors on Tuesday And we re doing that right now We started our password sharing initiative in June That kicks in in earnest in September By the way we ve had no backlash at all to the notifications that have gone out and to the work that we ve already been doing It s unclear how much Disney will charge US customers to share their account with someone located outside of the primary household Netflix charges an extra per month per additional household and that strategy has paid off It s also worth noting that the expanded password sharing crackdown is scheduled just before Disney increases its streaming prices yet again Most Disney Hulu and ESPN plans are going up by or per month in October The ad supported Disney and Hulu bundle is going up from to per month as well Iger added that along with bolstering the programming slate Disney needs stronger recommendation engines ーsomething that s being worked on ーand more efficient marketing to keep viewers engaged and paying for the service every month or year To help with that the company will soon start rolling out what it s calling continuous playlists These are effectively cable style channels that will stream around the clock The first batch includes ABC News Live and a playlist of TV shows and shorts for pre schoolers Meanwhile Disney revealed that its streaming business is now profitable Disney alone reached profitability for the first time in the January March period while the entire direct to consumer DTC business was million in the black last quarter That s a stark turnaround from the million loss Disney Hulu and ESPN collectively posted a year earlier Disney said the business became profitable one quarter earlier than expected The company is also planning to roll out a fully standalone ESPN streaming service next year Venu a joint sports streaming venture from ESPN Fox and Warner Bros Discovery is slated to go live this fall but that service is facing an antitrust backlash from rivals and lawmakers This article originally appeared on Engadget at	2024-08-07 18:41:23

海外TECH	Engadget	Fujifilm X-T50 review: A big improvement (for a lot more money)	https://www.engadget.com/cameras/fujifilm-x-t50-review-a-big-improvement-for-a-lot-more-money-180046809.html?src=rss	Fujifilm s X T II is one of my favorite cameras as it offers many of the capabilities of the higher end models for a lot less money So I was particularly excited when the company launched the X T which is like a miniature version of the X T It shares many features including a megapixel sensor K P video support and in a first for the series in body stabilization At the same time it retains the small size and retro cute styling of past models At it s not nearly as affordable as the X T though To find out if it s worth an extra half grand I tested the X T out in London with some professional photographer friends Body and handling The X T is all about portability and style so it s nice and light at grams pounds just grams more than the previous model If you re traveling with a compact lens it can easily be slipped into a bag At the same time the grip has been enlarged enough to make the camera easier to hang on to Operation is largely unchanged with two control dials a shutter speed dial and an exposure compensation dial along with a joystick and eight buttons However Fujifilm did introduce one new trick a film simulation dial in place of the previous drive mode ーmore on that shortly All of that makes it nearly as easy to control as much larger cameras The dedicated shutter dial is an unusual feature these days so it does take some getting used to The advantage is that you can see that setting just by looking down at the camera a must for discreet street or travel shooting Like past models in this series the X T has a tilt only display that doesn t flip out which is likely a bummer for the vloggers it s tantalizing with its video capabilities And rival models like the Sony A and Canon R do have flip out displays The million dot electronic viewfinder isn t super sharp but is par for the course in this price range With a smallish battery like the one on the X VI the X T can manage just shots on a charge or in economy mode That s near the bottom in its category By comparison Canon s like priced R can take up to photos before the battery dies The X T has a decent array of ports including microHDMI USB C and a mic jack As before there s no headphone input but you can use the USB C slot with a mm adapter to monitor audio It comes with a single but fast UHS II card slot Performance If it s pure performance you re after the X T probably isn t for you Burst speeds are decent at up to fps in electronic shutter mode or fps with the mechanical shutter ーfar from the fps of the Canon R in electronic mode Also the electronic shutter is only good if your subject doesn t move too quickly as rolling shutter distortion is very noticeable in this model Steve Dent for Engadget Autofocus still isn t a Fujifilm strong point either When I was shooting quick moving subjects it was a bit hit or miss in continuous mode particularly when they were close to the camera However performance depends greatly on the lens being used On top of face and eye detection Fujifilm has added subject tracking autofocus modes for animals birds cars motorcycles airplanes and trains This feature is completely separate from the regular eye and face detection modes so you have to dive into the menus to switch between them or program two separate buttons For the other types of photography it s designed for the X T s autofocus works well though it isn t quite up to Sony Canon or even Nikon s standards A key new feature is in body stabilization With up to seven stops of shake reduction you can get sharp photos down to about a quarter second That s the same as the gram X T which is quite an accomplishment given the size difference It makes the X T far more versatile letting you blur motion to create interesting shots or shoot in dark environments Image quality With the same MP sensor as the X H and X T the X T offers a major boost in resolution over the MP X II On top of boosting sharpness the extra pixels make it possible to crop in something that s handy for travel photography wildlife shooting or anything else where you might not be able to get close to the subject In camera treatment of JPEG files is handled well with pleasant accurate colors and just the right amount of sharpening and noise reduction You can often share photos straight out of the camera with no need for any post processing ーan advantage for street and other photographers who don t like to mess around in post The bit RAW photos offer plenty of room for fine tuning as they retain high amounts of detail in highlights and shadows As such I saw low levels of banding noise and other artifacts at low ISOs in all image areas Steve Dent for Engadget The higher resolution doesn t hurt image quality much in low light either Noise is controlled well up to ISO and you can go up to ISO in a pinch Considering that the X T is an APS C and not a full frame camera I was impressed with the lack of noise when shooting in bars and other dim environments And of course the X VI offers Fujifilm s full array of film simulation modes and they re easily accessible on the new dial You can experiment with popular looks like Velvia Eterna Acros black and white and others It also comes with Fujifilm s new Reala Ace based on one of the company s old negative films At the same time you get a RAW backup in full color so you re not locked into a specific look Video With excellent video specs the X T is a solid hybrid camera as long as you keep in mind some caveats ーparticularly around cropping and sharpness Much like the X T you can shoot K at fps with a x crop or K at up to fps with line skipping and a x crop The cropping occurs because K video only requires megapixels and the sensor processor combination isn t up to the job of supersampling the entire sensor width Steve Dent for Engadget The camera also offers sub sampled K at up to p using the full sensor width or high quality K p with a x crop For super slow motion Fujifilm also introduced bit and F Log settings for extra dynamic range At K and K HQ rolling shutter skewing is pronounced so you ll want to avoid excessive or sharp camera movements Sub sampled K is better in that area but video is noticeably less sharp Video autofocus matches what I saw with photos meaning it was decent but not ideal for moving subjects The AI powered AF did lock onto subjects but again couldn t always keep up with birds animals or vehicles Handheld video is now a realistic option with in body stabilization It works well if you don t make abrupt movements and the boost mode offers near tripod like smoothness Digital stabilization is also available but isn t supported with the K or HQ modes and doesn t reduce jolts when walking Video quality is solid for such a small camera offering the same accurate colors I saw in photo modes Shooting in bit F Log made it possible to adjust footage considerably in post or get creative You can also shoot video using the film simulation modes if you want a specific look straight out of the camera Wrap up Steve Dent for Engadget All told the X T is an awesome upgrade to the X T II with improvements in nearly every area ーparticularly resolution stabilization and video The film simulation button is a bit gimmicky but it should appeal to fans of the brand particularly those who love the X VI The problem I have with this camera is the price The X T II was easy to recommend to buyers on a mid level budget However at the X T is only less than the superior X T and at that price it has lots of stiff competition from the likes of the Canon R and Sony A along with full frame models like the Canon R Nikon Z II Z Zfc and Panasonic S Fujifilm likely figured that the X T was nearly as capable as the X T and that the megapixel resolution beats out rivals ーbut it has priced a lot of potential buyers out of the market If you re looking for something that costs around the same as the X T II Nikon s Zfc is just as pretty and a lot less expensive This article originally appeared on Engadget at	2024-08-07 18:00:46
