Answer to question 1: Why doesn’t the video play?
The reason for that is likely your browser does not support WebM videos. You’ll need a device and browser capable for that. If the video halts or skips, please allow more time before playing. An 8 mbps connection speed minimum is required, which may not be available to all mobile users.
Help with viewing the 4K videos:
To provide you an ad-free viewing experience with over 550 videos that you can share preview clips with however many, OneDrive by Microsoft is used to serve 4K 10 bit video previews. Vimeo is now also being served, just not in 4K for every collection yet.
Be aware of the drawback of 10 bit 4k: There are steep hardware and display requirements for HEVC 10 bit video playback. 1080p and lower previews are still h.264 and widely compatible, all videos play in 8 bit SD or HD unless downloaded (see below).
But first, here are PC specifications recommended for playing 10 bit 4K at 60fps:
|Windows Desktop PC|
|CPU||7th Generation Intel Core i7 processor, AMD Ryzen equivalent or newer|
|Graphics card||NVIDIA GeForce GTX 1050 equivalent or better|
|RAM||4 GB or more|
|Windows 7 or later or other compatible OS|
3820×2160 resolution, Rec. 2020 color primaries capable
Editor or player that supports HEVC 10 bit (Movies and TV app in Windows 10)
Mobile devices (OSX, Android Pi and later): Some phones will be able to play the files but are not all equipped with 4K screens.
macOS: ‘Pro’ models from 2016 and later may suffice but your experience may vary.
With the advent of 10 bit HEVC in 2013 (the evolution of h.264, aka h.265, High Efficiency Video Codec- HEVC) banding gradients on shareable videos can be nearly wiped out entirely. Banding gradients on smooth areas (like skies) has always been a weakness in general for streaming video- but 10 bit video profiles nearly eliminate postering and banding. Now efficiency and quality can go hand in hand, but both a 4K display and newer system are required- not everyone will be able to view these at the quality intended. Browser support needs to come before streaming can be made available of 10 bit HEVC.
Quality and resolution while streaming: On this site, you’ll always have a lower quality preview stream than downloading the clip locally. That said, there may not always be options to reduce the resolution for those with a lower display than full HD or who do have HD but don’t want to go full-screen.
To easily download 4K, 10 bit video and watch it on your system:
1: With the 4K media window browser open in your browser, select the download icon & choose where to download the file preview, if prompted to.
2: AFTER the video has completely downloaded, play the file. There are many options for streaming, all of which are only 8 bit, hence the ‘Low Fidelity’ note in the filename. Use the ‘Movies and TV’ app with Windows 10.
If you can’t play the files with the above specs and are fully updated, your device may not be HEVC compatible- you can still view and stream h.264 HD from this site!
Resolution guide for choosing the best for you:
3840×2160 (or greater): 4K Ultra HD (download only) on the homepage* *10 bit HEVC video player or editor required.
1920×1080 or above (but less than 4k): 1080p HD, found on all the collection pages. 8 bit streaming and downloading from there, all marked as ‘low fidelity’.
1280×720 or above (but less than 1920×1080): 720p streaming, select the option in the media player.
Less than 1280×720: Standard definition 360p, select the option in the media player.
Streaming video dips in quality: When you open a video you may see video quality on this site start low; adjust your video resolution. ProRes previews are not currently available for all clips but create a proof request if you need to have some prior to purchase and license.
4K requirements are so steep because of the sheer amount of data moving in time-lapse clips. Specs that can barely run 1080p may run not as smooth because of the demand time-lapse puts on the data rate, especially in instances when scenes change, or clouds move quickly.
