The original of the clips on my site is on AVI. Now I got some requests from film libraries - but they want HD format. Question: has anyone experience of ?upgrading? from AVI to HD? I guess it must be pretty bad - but how bad is it?
Thanks for replies.

Depends how big (pixel dimensions) your clips are. They seem to be 4:3 origin, then squashed to square for display on the site. Remember HD is 16:9 ratio, so your clips will be displayed with black bars down the sides. From my experience up-res can look quite bad unless you have high quality originals (i.e. not too compressed). Were they shot on film originally? Might be worth getting the telecine done again to HD format. Shouldn't cost too much as they're quite short clips, and must be quite popular? Great iconic Ozzie images :-)

Thanks for your reply and detailed pictorial explanation. Yes, the clips were shot originally on 16mm film. Unfortunately, after transfer to AVI, I lost the negative.
