Hello,
although it is discussed here

how to remove sparklies, i think i'd start a new thread for my question.
I digitized ~45 minutes of DV material in premiere pro, originally shot on an XL-1, digitized with the same camera. i edited the stuff for some hours and due to lack of time put it on hold for a couple of weeks. during that time i had a problem with my firewire port, the infamous "delayed write error" caused by profilic firewire chipsets, so i digitized on an external USB2 disc BUT all of the digitized material was perfectly ok, no dropouts, no skipped frames, no sparklies.
when i opened the project again it suddenly had sparklies all over the movie. i searched the web extensively to find an idea of what could cause this, tried almost every available DV (canopus, panasonic, cedocida, ffdshow, microsoft) codec and players / editors (VDub, Premiere, MPlayer Classic, VLC) but the sparklies are there to stay.
unfortunately i cannot compile the cedocida_mod (http://stud3.tuwien.ac.at/~e0125662/) with added analyzer which might have been interesting...
what i ask myself, is the file corrupted now and if, how did it happen - or is it just a question of the correct filter graph, using the right codecs, etc.
The thing which really makes me wonder is that i am absolutely sure that the file didnt have errors in the first place, either they were hidden by some error correction or they havent been there at all.
Anyone have a clue ?
