It may be useful to also cross-post this question to the IIIF-discuss list [1]. There is a lot of interest in developing a IIIF-like approach to presenting video via a common API, and one that lends itself to web-based annotation. This would allow theoretically allow users to annotate videos with their tool of choice, and to be able to reuse / export the annotations to any other tool.

I expect this will be a topic at the next IIIF meetings, in New York City (May 10-13, 2016). [2]

This may or may not be relevant to the "annotation" that the original
poster had in mind, but the Internet Archive embedded video player
takes subtitles in the common SubRip .srt format, which is apparently
supported by many video players & subtitling programs.

Instead of using this for closed captioning, you could use it for
annotations. Each video can have multiple .srt files, with the user
being able to pick which one is shown. I'm not 100% sure if our embed
code allows the embedder to choose one .srt to be shown by default,
that's where my knowledge ends.

Hi Stuart,

A colleague of mine has just recently recommended Clipper ( they're
currently experimenting with it in the EUscreenXL project.

Might be worth checking out for you as well.

Curious as to what others will suggest as well.

Thanks for sending out that document, Erwin.

This is a really interesting topic and I feel like video annotation on the
web should be more of a thing.

On top of what Erwin already provided (OVA looks particularly like A
project that might be good to look at for your needs) there are also: - which is a proof of concept using the
open annotation specification ( The
specification is format agnostic, intending annotatation of objects with
text, media, web resources etc. - the folks seem to be
involved. - pretty basic, but appears to get the job done and is
web based.

There are scads of proprietary and open source desktop video
coding/annotating software that I will spare you the burden of going
through. Full disclosure, I work on a project whose sibling project is a
desktop video coding tool for psychology researchers.

From my vantage point, video annotation software generally seems to be
developed around a specific set of user needs (a type of researcher and
research subject, for example). More specific target audience gets a more
robust set of tools targeted at those needs.

The biggest issues come down to diversity of encoding for video and the
ability for operating systems to support the playback of them. This said,
the web has even more limitations around what video formats it will
support, but if you control the source of the video, this might not be such
a big deal.

It would really be great to see video annotation for specifically DH
projects warm up.

Have a look at all the resources and determine whether you think it might
be useful just to roll your own annotator using HTML5, some sophisticated
JS libraries for handling media, and hopefully wrapping in a standard like
the Open Annotation Data model (linked above).

Would love to hear what others think/may have experienced.

Dear Stuart,

A few years ago we started an overview of video annotation projects and
tools for the EUscreen network. We haven't been able to turn it into a
state of the art document as of yet, but I'm hoping it would be useful
such an endeavour:

I am doing some discovery for a DH project that, at its center, needs
annotate digital video (locally produced videos that will be hosted and
streamed on the web in our local environment).  We are still gathering
requirements, but it needs to:

 *   have a user friendly interface for creating annotations, better
the web but not an absolute requirement
 *   create annotations at specific timestamps, or across spans of
and have those annotations associated with regions of the video image.
 *   annotations could include, text, audio, video, image, URL, etc.

We’d prefer open source solutions that can be integrated into a web
but aren’t fully closed to alternatives.  We’d strongly prefer a
that supports open standards for annotation or is at least capable of
supporting open standards.

I know there are many, many video annotation projects.  What is the
current state of the art in web-based video annotation making and

Many thanks,
