Prior to 2008 all footage was record in standard SD format and with the exception of the 2006 footage, in Full Frame 4:3 format with a Dolby 2.0 audio soundtrack.
In 2006, whilst still recording in SD format, recordings switched to the then new Widescreen 16:9 format and the audio to Dolby 5.1 Surround Sound soundtrack.
Since 2008 I have been recording in HD format only with video in the Widescreen 16:9 format and audio in Dolby 5.1 Surround Sound to give me the best possible source video to use to create these DVDs.
Throughout the years I have always used Sony camcorders and to create these DVDs which is in SD format, the HD footage has been edited and converted from the original AVCHD format to MPEG2 so that it fits onto a standard DVD and plays in a regular DVD player.
For the DVDs its important to note that the footage has been converted from HD to SD format however you still get the clarity of the HD recording which can be seen in the following examples - the images on the left were recording in HD and converted to SD whilst the images on the right are from recordings originally made in SD. To maximise value for the DVDs some contain up to 3 hours of footage. In these cases the compression required to squeeze that much data onto a DVD has resulted in a small loss of quality but no one has complained so far.
