We perform independent comparison of cloud-based video-encoding services. This kind of encoding tools is quickly gaining popularity and selecting one for your tasks is quite difficult. In our experience, encoding performance may entirely differ from service to service. The results of our previous comparison showed that in the case of cloud services that provide the same quality, the file-size difference can reach 100% and the cost per minute difference is 700%.

Comparison main points

  • Encoding time and objective videos quality are measured
    We perform a series of measurements to estimate average time needed for transcoding. Subjective comparison and objective algorithms are used for estimating the resulting video quality
  • Two encoding use cases: default encoding options and options provided by service maintainers
    This year we will perform two types of tests: encode test videos using service default encoding settings and using the settings recommended by service maintainers for our scenario. If no settings are provided we will do our best to find and use optimal encoding settings (for example, see "Tunned Qencode" in the previous comparison report). If a service does not have an option to vary encoding settings, it will not be presented in the second test case
  • FullHD videos of different type and content (including UGC, vertical and noisy videos, etc.)
    5-10 FullHD videos will be used for tests. We will perform two types of measurements: the main case involved encoding into FullHD, and the additional case will include transcoding into several resolutions (the results will be published in the report appendix)
  • Cross-checking is performed by industry experts and independent users
    We ask the users of participating services to encode several videos from test set to validate the results
  • Anonymous accounts are used for testing
    For fair comparison, we use accounts which are not connected to us as the comparison organizers. This is done to prevent the services reserving separate servers/rules for comparison test videos processing

Comparison Stages

1. Application
February, 18 - April, 10
Application for participation is open for all cloud encoding services and users!

Use the form to tell us which services you want to see in this comparison

2. Measurements We encode comparison videos in each service and measure encoding performance

3. Verification We conduct independent cross-checking of obtained results. You can become a contributor and verify comparison results. If you have an account in any of cloud encoding services, we will provide test sequences and pay for encoding time which needed for measurements

4. Release PDF and HTML reports are published on this page. There will be two versions (free and enterprise). All contributors will receive full (enterprise) report

List of services to be compared

Take part in cloud video-encoding services comparison

We ask users of cloud encoding/transcoding services to take part in this comparison by encoding several videos to compare the results with our measurements. Approximate timeline of verification measuremets for contributors:

  1. We send you several videos for encoding
  2. You send us compressed video streams
  3. We analyse the results and prepare a report
  4. You receive enterprise version of the report

If you have an account in any cloud encoding service and want contact us usint the form below. We are ready to compensate the cost of encoding.
