Just an update on this.
I have spent a little more time on the converter and now it is preforming pretty well.
It can now handle syncs which have jitter which it couldn't before.
The converter in now fitted into a Hedghog II along side the 625 to 405 converter that was already there so it can be switched to convert either way.
Just a bit of cleaning up and tweaking to do before I can release it.
I have no suitable VCR to try the converter with.
But I have a number of 405 test card generators with varying degrees of poor sync. They have helped a lot while trying to improve how it copes with poor sync.
The link below is a clip of the converter working. The 405 video is from one of one my test card generators that has really rubbish syncs. Any apparent improvement in the converted video is down to the modern monitor been better able to cope with poor syncs rather than the converter improving it.
