Womble MVW for cut/join video streams + sync detection, SoundForge for seamlessly joining audio.
TDA3 for authoring from the resuting video and audio streams.
on archive source (3 songs + intros) timecode is now perfectly hidden with BBC logo (no more jumping digits). On Woodstock** UK ARENA logo filtered out (no cropping, of course).
Audio for the above pieces taken from lossless CDR source also coming from video tape (15625 kHz TV line frequency trace on spectrogram, also it can't be from a broadcast - no cut-off until 22.05kHz, half of the audio CD sampling frequency 44.1). It is mono (as all sources are, judging by waveform in SoundForge) and inferior in quality to MP2 stream of the BBC DVB, for this reason it was not used for the rest of material. There was also some static, mainly in right channel, so audio from left channel was used for replacement.
I didn't use any material from the older BBC4 broadcast torrented as 'trade DVD source', it proved to be modified: opening it in VDubMod shows it was deinterlaced (=re-encoded). And the picture is not as sharp as in the DVB source used here.
I tried different ways of editing material and making a DVD from those sources (cutting off time code with centering the rest, making different options for playback with and without duplicating DVB material, etc). All that worked but did not satisfy me, this version is the one I like.
