There is a (sometimes) heated discussion on DV-L about the effects of effects and transitions on DV.  Some claimed that your image would immediately disintegrate once you add effects. Some said it wouldn't work at all. Some said: "Hey, no problem!" To settle the issue, I wanted to offer some kind of proof. Until there's real streaming video on the net (and we all have T3 lines), all I can offer are some stills. As customary on many  web sites, I chose the obligatory pictures of wife, house, and dog for the experiment. 

How these pictures
were done.

Footage was shot on-location in the pre-springtime Hamptons on Long Island, NY. My wife & dog did not sign a release form and will probably sue me. 
--
Camera: Sony PC7.
Footage was then copied from the PC7 to my computer using an Adaptec/DPS  Spark.
--
The footage was brought into Adobe Premiere for editing.
Titles were created in Premiere.
For the titles, I used some fancy shadows to show rendering of subtle effects. 
During titling, I made sure that I didn't use NTSC-illegal colors (Premiere tells you what's legal and what's not.).
--
To the titles, I added the following filters: Anti-alias and Blur. This is always a good idea for titles.
The titles were added to the clips using a White Alpha Matte for the Transparency setting.
The combination of the title and the clip was then rendered into a DV clip, using  Adaptec's DVSoft codec, which comes with the Spark. No additional filtering was used on the clips.
--
The resulting clips were sent back out to the PC7 for previews. They looked great.
--
Caveat Web.
The stills do not show the clips in their full beauty. Here's why:
To show the clips on the web, I had to make stills from the finished clips using Premiere's "Export to Bitmap" option.
The bitmaps were then brought into Adobe Photoshop and resized from their original 720x480 size to 420x280 pixels. This needs resampling and impacts on the picture quality.
To make loading time halfway tolerable, I had to compress the resulting bitmaps into JPEG pictures. This results in a further loss of quality and some staircasing if you enlarge the pictures a lot.
But considering all that, they look pretty good. What's most important: As the pictures on the right show, titles and transitions with DV & Premiere work great
Also, if your computer screen cannot show gadzillions of colors, you won't see the pictures in all their beauty...
If you want to see the original *.BMPs, then you can download them for closer scrutiny. Careful, over a Meg each. Mark Hood converted the BMPs to high-quality JPGs. 


Titling & overlay tests. 

These stills are from clips processed with the Adaptec/DPS Spark, edited with Premiere and then sent back to DV using Adaptec's DVSoft codec. Bookmark this page in case someone tells you scary stories about the quality of the DVSoft codec, or the quality of DV in general. For details, see "How these pictures were done" in the sidebar. 

Update: Some folks insinuated I cheated, because I sized the pix down and then recompressed them with JPEG. Of course this is everything but cheating. Sizing down and recompressing in JPEG degrades the pictures! For a couple of days, I made the original *.BMP of my wife available for ftp download. DV-L listmember Mark Hood graciously volunteered as an "independent party." He converted the BMPs to high quality JPEGs. He hosts them on his server, along with the original BMPs. Links to the images are given with every image. 

Please allow the images to load! 
They load in progressive scans and get better as they load.
