Canon HV20/HV30/HV40 is a great choice for HD-happy amateurs, but its low-light performance could have been better. HV20 and HV30 wrap in 60i. Some confusion on if HV40 does/did the same. When it was launched it was claimed to be different, but in practice is it? It's still a single CMOS sensor, and still HDV. And still looks a bit washed out without color grading IMO.
HDV stores the video as 1440 horizontal pixels by 1080 vertical pixels. FULL HD is typically 1920 horizontal and 1080 vertical. Both are 16:9 aspect rations. HDV is an mpeg2 codec and FULL HD / AVCHD / AVC1 is an h264 codec.
No matter what, if you have a Canon HV20/HV30/HV40 for shooting HDV 60i footages, you will have a problem of displaying the video with many interlaces. So before sharing your HDV footages with family, or before editing the HDV files with FCE/FCP/Adobe Premiere Pro/iMovie, you need deinterlace/convert Canon HV20/HV30/HV40 HDV (60i) files to HDV 1080p24 (*.mov) or HDV 720p24 (*.mov).
Aunsoft Video Converter for Mac as the recommended Canon HV20/HV30/HV40 HDV (60i) files to Apple HDV 1080p24 (*.mov) or HDV 720p24 (*.mov) Converter on Mac. It does not only allow you to trim and crop HDV footage, but also deinterlaces/merge HV20/HV30/HV40 HDV 1080i videos, convert 1080i to 1080p.
Below is the simple guide about how to deinterlace/convert Canon HV20/HV30/HV40 HDV (60i) files to Apple HDV 1080p24 (*.mov) or HDV 720p24 (*.mov) for FCE/FCP/Adobe Premiere Pro/iMovie. It also works for iMovie 8/9 and even 11.
Step 1. Download Canon HV20/HV30/HV40 HDV videos to Aunsoft Video Converter for Mac. Click the "Add" button to download 1080i .hdv files from camcorder to the application.

Tips: Pros and cons of MPEG-2 HDV vs H.264 AVCHD
Mpeg2 doesn't require a lot of thinking by the computer. H264 does require quite a bit of decoding to render (or convert). Let’s call that speed. So mpeg2 is faster. But mpeg2 (HDV) isn't as efficient and relatively wastes bits. With a minor trade off of having more bits (25Mpbs CBR) and fewer pixels to represent with those bits (1440x1080). If it were h264, it would be better. But since it's not and h264 is more efficient, h264 (AVCHD) is generally considered better. Relatively anyway. They're both compressed and lossy.
