Rendered up a bunch of versioned stings (340 frame each - PAL) as qt. mov [tiff uncompressed] as I normally do. Imported into our Unity in the usual fashion, using the normal 601 settings and got some absolutely ghastly artifacting around some strong reds and blues. I've looked at the original qt movies, and they're very clean. I made sure the reds and blues were not too saturated, and definitely legal, but i've got some jaggies that really take some beating!!! The graphics are made up of boxes in perspective, so I've got plenty of straight diagonals with reds and blues on one side and some fairly unsaturated colours in the bacjground on the other... I can only think these clashes are causing the artifacts, but desaturating the colours leaves me without the impact of the Election Party colours!
Maybe there is another way of cheating in these files, whilst preserving my colours. Ouch.
[David Jones]"Are you running the Avid uncompressed or at 5.1 DV compression?"
Well, according to our import options on the unity we're importing at dv 25 420 PAL. Whatever compression ratio that is - it's significant(ly crudulous). Everybody's footage gets ingested thus. I believe I'm correct in thinking I cant place an uncompressed file onto the Unity. Unity, by nature of the dv pipeline, compresses all the media ingested in the same fashion. I am however, rendering an uncompressed file to another "storage area" prior to importing into Unity and the editors assigning a video id for tx.
It's not as if I haven't placed some hard, fast, colourful gfx into Unity before, but this particular combination of sat/desat composition has really yeilded some nasty drawbacks to dv compression that have forced me to rethink the design. Now that is a real limitation.
