I recently posted a request for video test clips on LinkedIn. This article summarizes the websites listed in the responses. Thanks to all who responded.


An absolutely fabulous resource for compressionists looking for a broad range of 4K footage of reasonable duration, many, like this NY promotional clip, in HDR. Here’s the site description. is intended to demonstrate the latest in video content evolution and technology. This content includes encoding technologies, 4K Ultra-HD (UHD), High Dynamic Range (HDR), higher frame rates, and greater bit depths. 4K Media seeks to facilitate the evolution of the video-content industry by allowing this content to be used freely for testing, demonstrations, and advancement of technology.

I will be using a lot of clips from this source going forward.

3GPP DASH Sequences

A frame from one of the test videos in the DASH-WAVE-3GPP-5G Video sequences.

3GPP DASH sequences  – multiple very short (10 seconds or so) test clips in up to 10-bit 4k). Very good mix of footage from humans to text to gaming.

(i) Original dataset. This is one of the first (if not the very first) DASH dataset comprising video sequences of different genres with resolutions up to 1080p encoded with AVC and packaged with DASH (bitrate ladder with 20 representations and segment lengths of 1s, 2s, 4s, 6s, 10s, 15s).
(ii) multi-codec dataset. An extension of the original dataset comprising multiple codecs, i.e., AVC, HEVC, VP9, and AV1, with a single MPD for multi-codec testing purposes (resolution up to 4K, segment lengths 2s and 4s).
(iii) Multi-Codec Ultra High Definition 8K MPEG-DASH Dataset. Extension of the previous datasets comprising multiple codecs, i.e., AVC, HEVC, AV1, VVC, with a single MDP for multi-codec testing purposes (resolution up to 8K, segment lengths 4s and 8s).

American Society of Cinematographers

STEM2 Video test file from the American Society of Cinematographers is available in various high-quality formats.

The American Society of Cinematographers – Stem2 – (from the site): “A short film created by the American Society of Cinematographers Motion Imaging Technology Council designed to be used as reference material and stress testing for color pipelines, image processing, monitors and projection systems. Supplied in various image formats including high dynamic range (HDR), high resolution, and wide color gamut.” Like Meridian, but longer and more varied.

Noa is the hero of the short film Spanner, created by AWS’s in-house production team FuzzyPixel.

The American Society of Cinematographers – Other content is available on the American Society of Cinematographers website, like the character above, a completely animatable main character represented in Maya, with rig, geometry, textures, and hair groom. Also includes a useful mix of primitives from different production mediums.

American Society of Cinematographers Digital Product Example Libraries – A list of production libraries and content from various sources, including Disney, Amazon, Epic Games, Sony, Pixar, and many others. Links to other sites, including many listed on this page. A great place to check for high-quality test content available in pristine production formats.

Awesome Video Testing 

A pretty awesome list of video-testing tools and video-test clips. For example, I found the 4K Media site on this list, and there are many others that I didn’t present separately here.

Cablelabs 4K Video Website

Video from the CableLabs 4K video website.

Another fabulous site of about ten ultrahigh quality movie-like clips of moderate duration (3-5 minutes). Downloadable in ProRes format in various HDR formats, with many at 98 fps. Here’s a description from the site.

“This website is dedicated to providing video content for free under the Creative Commons License. It is intended to showcase cutting-edge filming techniques, ultra-high resolution, expanded color spaces, high dynamic range, and more. Consumers, distributors, and vendors can use this content for demonstrations, testing, and entertainment purposes.”

The Consumer Digital Video Library

Here’s the description:

CDVL is a digital video library intended for researchers and developers in the fields of video processing and visual quality (both objective and subjective assessment). Progress in these areas has been limited by the availability of high-quality royalty-free test material. CDVL provides relevant video clips for different types of video processing and quality measurement applications. This fills a critical industry need.

From a colleague on LinkedIn: “The CDVL ( archive is unique and super helpful if you are looking for public safety-specific sequences. It’s a niche, but if you are in the business of developing surveillance systems, it is critical to use domain-relevant material (which is quite specific for public safety, e.g., flashing strobes on a police car) vs. Hollywood or talking-head material.”

DASH-IF Test Vectors 

Different test files available on the DASH-IF test site
Different test files available on the DASH-IF test site

DASH IF Test Assets Database: An invaluable site for those testing particular DASH-related features. This is from the site:

  • The goal of the DASH-IF Testvector database is to allow a dynamic management of the test vectors provided by the DASH Industry Forum. This includes:
    • Categorized DASH-IF features and feature groups
    • Test cases for the individual features.
    • Test vectors for the test cases.
    • Dynamic management of the attributes all the models

Other DASH Datasets are:

ITEC – Dynamic Adaptive Streaming over HTTP

Here’s the description:

Here we offer three datasets. The first dataset conforms to the newest version of the MPEG-DASH standard. The second dataset provides content encoded using Scalable Video Coding (SVC) and provides MPDs according to the newest version of the MPEG-DASH standard. The third dataset was created by Stefan Lederer and is still listed here for compatibility with the VLC Plugin.

ITEC – Dynamic Adaptive Streaming over HTTP

Multi-Codec Ultra High Definition 8K MPEG-DASH Dataset:

Derf’s Test Clips/ Video Test Media Video Test Media [derf’s collection] has many iconic and modern video test clips.

Derf’s Test Clips – Officially Video Test Media [derf’s collection]. An amazing range of test clips from the iconic Akiyo and Forman to most of Twitch’s game videos and Netflix test sequences, plus Big Buck Bunny, Meridian, and an Amazon HDR education test reel. Generally, the best first stop for anyone searching for useful test clips.

Fraunhofer – 8K test sequences

The sequence provides a view of the Bode Museum in Berlin.

Fraunhofer HHI made a set of seven 8K sequences publicly available. The sequences were taken in fall of 2019 at different venues in Berlin. Each sequence comes in a BT.2020 SDR and a BT.2100 PQ HDR version. A fabulous resource for those seeking multiple 8K videos in SDR and HDR versions, though the range of content is limited.

Google – YouTube UGC

This YouTube dataset is a sampling from thousands of User Generated Content (UGC) as uploaded to YouTube.

This YouTube dataset is a sampling from thousands of User Generated Content (UGC) uploaded to YouTube and distributed under the Creative Commons license. This dataset was created to advance video compression and quality assessment research of UGC videos.

Regarding quality, the site states that users and creators upload UGC videos. These videos are not always professionally curated and often suffer from perceptual artifacts. For the purpose of this dataset, we’ve selected original videos with specific and sometimes substantial perceptual quality issues, like blockiness, blur, banding, noise, jerkiness, and so on.

A great site for those researching issues relating to UGC quality, but otherwise limited for most video quality testing.

The Internet Archive

One small step for man, one giant leap for mankind.

Got some extra time? Over 9.7 million videos are in this collection, including movies, TV programs, news programs, and other assorted content. Well-indexed and highly searchable, better for documentary producers than codec testers. A national treasure.

Jellyfish Video Bitrate Test Files

The Jellyfish Video Bitrate Test files collection contains one clip, encoded to dozens of variations.

This site includes just a single video of a jellyfish shown above, but it’s encoded into dozens of bitrates, codecs, codec profiles, and color depths, from 1080p @ 3 mbps in H.264, HEVC, and 10-bit HEVC, to 4K video available in the same codecs at up to 400 Mbps. This is a fabulous resource if you need this range of sampling and don’t want to create it yourself.


Nocturne video test clip from Netflix, available in 60 and 120 fps display masters.

Netflix Open Source Content – Multiple downloadable test clips, including Sol Levante, Nocturne, Sparks, Meridian, Cosmos Laundromat, Chimera, and El Fuente, available in a range of very high-quality formats, including 4K and larger, HDR, and ultra-high frame rate (120 fps) content.
