Nigel S's recent activity

  • It certainly isn't an easy task, and real time encoding in cameras will certainly need dedicated silicon, but there is currently a vast effort being put into this with the top companies involved, ...
  • It is supposed to be designed so that it can be decoded in software on most existing hardware, don't seem to have quite achieved that for decent resolutions and frame rates yet, but they are still ...
  • Decoding is pretty quick with the latest decoders, and the encoders are also getting considerably faster, yes still slow, but no longer ridiculous unless you ask it for maximum quality. However in ...
  • I think he is correct, the new global standard for image files will inevitably support 10-bit, HDR and improved colour, just like the new global standard for video will. We have been using jpg ...
  • Not a lot of colour in Antarctica, a lot of white but not much colour. However with all that bright snow there is huge dynamic range; so much that your eyes can't cope and need protection from snow ...
  • Replied in Adoption
    I replace the wheel bearings when they start to squeal so that my wheels never fall off! I think it is fair to say that the AV1 video standard has already been widely adopted by the majority of the ...
  • The compression used is AV1, based on the video codec (much nicer compression than jpg), the result of the compression is stored in files of the HEIF format which just provides the container, not ...
  • The wording suggests they will use an existing one: "There are many such formats already in the market , but we need to study which one is best for the customer."
  • Most sensible would be: https://en.wikipedia.org/wiki/AV1#AV1_Image_File_Format_(AVIF)
  • Replied in Photo Goats!
    Two major problems: 1. Taking a goat for a long walk, while a nice experience, does make for very slow progress. You will travel at goat speed, not human walking speed. 2. Goats eat anything and ...
  • 2MP is plenty for the web, in fact most people still use Full HD monitors which are only 2MP so a photo on a web page is going to be a lot less than that, almost nobody has a display device ...
  • In my testing I've always seen obvious banding using HEVC encoded using ffmpeg, whatever the quality settings, not impressed at all. However using VP9 encoded in ffmpeg not only avoids the ...
  • The effect is due to the Bayer filter, pure red light is only seen by one in four pixels, so the image has effectively only a quarter the normal resolution, furthermore any sharpening algorithms ...
  • That is how long it takes the train to get from China to London: https://www.bbc.co.uk/news/business-38654176 If it does go by plane then it will be a cargo plane where the regulations for ...
  • In a USB powerbank, it is the powerbank that contains the charger and thus it is impossible to charge it faster than it was designed to be charged. You can buy wall adaptors (sometimes called ...
  • Note that Lead Acid car batteries are far more dangerous, they can and do explode due to hydrogen build up and the explosions can shower people with battery acid causing blindness and occasionally ...
  • That was an RC aeroplane battery, and while only 8000mAh is capable of discharging all that power in a few minutes, not the 1.5 hours that an 8000mAh powerbank would need at  maximum discharge rate. ...
  • That can happen if they get too hot while fully charged, keep them below 60 degrees C and they will be OK, store them at around 50% full instead of 100% or 0% and they will last a long time. Same ...
  • You could try going here: https://batteryuniversity.com/index.php/learn/article/types_of_lithium_ion However it will take a lot of reading to come to a conclusion, and it is made more complex by ...
  • There is very little difference between lipo and Li ion other than the shape and the fact that Li ion are normally contained in a metal cylinder, the one that is a bit different is LiFePo4 which ...
