1. What settings are proper for a miniDV (camcorder footage hdv1080i) in effects lab?

2.I use quicktime mov files in effects lab n then render (what render settings are best to keep quality for my situation? I've tried mpeg4 video and dv pal and both lose quality and make my film look terribly pixelated.)

please help, any input is much appreciated as i have just started.

im on a mac n use imovie...i dont know if those details help..

Firstly, are you sure your video is pixelating, and that what you are seeing isn't just interlacing? Many people confuse interlacing, which is a totally normal part of how video has worked for 50 years, with a loss in quality, when in fact it isn't a quality issue at all. the article I linked illustrates interlacing, and explains how it works.

If in fact, your video is pixelating, and interlacing isn't the issue, let us know. But really, if you are using .mov footage, I'd recommend using the Animation codec as a standard, as it is lossless, so you retain the maximum possible quality, but with significantly smaller file sizes than uncompressed. Plus, it supports alpha channels, if you ever need to work with them.

Use the "Export using Quicktime" option in iMovie, and you will be able to use the Animation codec there as well, to ensure no quality is lost.

I'm sure it is the codec or setting ive been using. when starting a project i use hdv1080i and widescreen and i believe interlaced odd...when rendering, i will now try animation codec, as well as playing around with the interlace settings to see the best results possible

thanks

miniDV cameras can't shoot at HDV1080i. miniDV and HDV are different systems (although they share a few similarities, such as using the same tape storage medium), with HDV being the high definition, high resolution one. miniDV can only be standard definition, such as PAL and NTSC.

So the first thing to do is figure out what exactly your camera is shooting. smile
