Watch this video if you are interested in admissibility process.
On the Court’s web pages you can find web casts of hearings before the court dating back to around 2007.
A video explaining the process for the supervision of the execution of judgements can be found here.
Many other videos are available on YouTube. They are, of course, of variable quality. The following are particularly noteworthy for the quality of their content regarding the UK-Strasbourg theme:
Professor David Feldman on, respectively, the prisoner voting issue and the Abu Qatada case; Nicola Padfield on the Vinter case; and this video by Dr Mark Elliott on the current situation (May 2015) as regards human rights law in the United Kingdom.
BBC ‘HardTalk’ interview with the Court’s President, Dean Spielmann (audio only).
This (2013) interview with former President Bratza is also well worth watching.
