iaincollins Update README.md
I've reformatted the instructions and incorporated some of the comments earlier in the ReadMe so people get a better idea of what this is.

I've removed the IBM Bluemix demo as it doesn't work on all browsers (and people might just stop there if they try it and it's confusingly broken).

The instructions are a little more generic (less mac specific) and a little more succinct.

Computer Assisted Video/Audio Transcription

This is a prototype web based tool for computer assisted transcription.

Once setup, you can simply drag and drop a video or audio file to start transcribing it.

Words the computer isn't sure about are highlighted for review and you can click to edit the text - which will also jump the video to the appropriate point and start playing it so you can review the transcription and correct mistakes in the auto-transcription.

With current Speech to Text technology you won't get a perfect transcription - the quality will vary a lot depending on the invididual speaker and the qualty of the source (broadcast quality audio recorded in a studio works well, interviews in bustling noisy venue not so much). The goal is to make transcribing easier and faster - and a lot of that comes down to getting the editor interface right.

Note: This is a prototype intended to gague interest and provide a base for further developement. It works reliably but you'll need to do some work to set it up and the functionality of the text editing is somewhat limited. If there is sufficent interest a hosted version might be made available in future.

Read more about this prototype on Medium.

If you do a lot of transcribing and work in journalism or the media and would like an instance setup and configured for you to try out or if are interested in bespoke news or media software development, get in touch with enquiries@glitch.digital.

Getting started

Registering for an IBM Bluemix Account

To setup this application you'll need to sign up for an IBM Bluemix account and select the Speech to Text API and obtain a username and password for the API (note: not the same as the login details for your IBM Bluemix account).

You can get a 30 day free trial of IBM Bluemix, and there after the first 1,000 minutes of audio every month is free to transcribe.

Installing dependancies

A UNIX based OS is required (e.g. Mac OS X, Linux, BSD, etc), you can't currently run the server on Microsoft Windows.

You will also need Node.js and FFmpeg installed.

e.g. To install with the HomeBrew package manager on Mac OS X:

brew install node ffmpeg

Install Node.js dependences in the usual way:

npm install

Starting the server

When running npm start to run the application you'll also need to pass in the username and password you got for the IBM Watson Speech to Text API by using the environment variables WATSON_SPEECH_TO_TEXT_API_USERNAME and WATSON_SPEECH_TO_TEXT_API_PASSWORD.

e.g.

WATSON_SPEECH_TO_TEXT_API_USERNAME="abc123-4567-8910" WATSON_SPEECH_TO_TEXT_API_PASSWORD="abcdefghij" npm start 

Once the server is running you should be able to open a browser to http://localhost:3000 and upload a video or audio file to transcribe it.
