I'm using the demo version and thought i was getting somewhere until i rendered the project. it looks absolutely terrible regardless of what settings i use.
i guess this is down to the fact it's a demo but cant seem to find any confirmation of that.

Nope, the demo renders exactly the same as the full version, with regard to quality. Though the demo does of course have a watermark. Poor quality can be caused by several things:

1. Poor source material. If your original footage is of poor quality, that will translate through the rendering process.
2. Excessive processing. Even the best of footage can be marred by inordinate or excessive use of grading filters.
3. Compression. Most often this is the culprit. Use of a poor quality codec, or turning the quality settings on your codec of choice down too low, will result in footage of poor quality.

What codec are you using? I don't mean the Render Settings window, I mean the Compression Settings window which appears after you select Render and name your file, where you select the codec and set the quality. If you select Uncompressed (labeled as None in the Quicktime menu), there will be zero quality loss. Although the Render Settings you are using would be helpful as well.

hello and thanks for the reply.
i've tried this using all 5 codecs after selecting avi in render settings and every option under mov. including uncompressed(on Mov and Avi) and always with maximum quality available. the difference between what i see in the preview pane and what i see in the rendered file is considerable. here's an example, even allowing for the fact that i'm pausing a moving image it's pretty bad.

here's what i see in FXhome:

and here's what the rendered version looks like:
http://www.sextonlovecraft.com/cap.jpg

that cap is from an uncompressed avi though all the other avi's are very similar. all the quicktime files are MUCH worse.
there are no filters or grading applied to the project and that background is a still image though i have tried it with others and got the same result.

Oh, that's just interlacing. Its not a problem, a glitch, or a bug, but rather the way that video works. If you are working with still images such as that, its best to set up a progressive project, rather than interlaced. Also, it looks like you may have the "Retain alpha channel" box activated in the render settings, which should generally be avoided unless you intend to do your final compositing in another application.

If you view that video on a television screen, the lines through the effects will not be visible. If you need to keep the project interlaced (if you are using DV footage, for example), but when it is completed wish to show it via the internet or a computer monitor, then the project should be de-interlaced as the final step.

More information about de-interlacing can be found at www.100fps.com .

i have managed to get a much better quality rendering now. though i'd tried the effect over a couple of stills and a couple of videos without usable results the reason was the videos had been recorded on my webcam at a different frame rate to the effectslab project i'd created.
when i render the project using a background video with the same frame rate the horrific amount of interlacing and general blockiness is gone.

thanks again for your help.
