HV10 and HV20 downconvert quality?

I'm looking for a small camera light enough to carry on a bike for days and days. If I were to downconvert the HD to SD would that 1/2.7 chip still be fairly sharp as compared to my heavier Sony VX1000 provided there was adequate lighting?

Hi Matt,
here's what I think: because of the immense decrease in resolution, the HD footage would have to be quite awful to notice unsharpness in SD resolution. The image would be scaled 3 times smaller (1920>640px of width) for NTSC and 2,7 times smaller for PAL. So yes, I think so. Even if you consider the 3CCD color resolution advantage the VX1000 has, the HV series cams would have no problem because of the headstart they have at HD resolution.

You may want to do the downscaling in post, though, as that is the only way to avoid the standard DV (YUV) color compression. Disadvantage: MPEG2 compression. Yes, always something...

Prepare for worse sound quality, however. At least the HV20 has ext. mic connection, although I don't know about that on a bike :). You might consider the DM50 microphone that fits on the HV20 hot shoe. I have it, it sounds okay.

...in short...a SD image scaled down from a HD image on the HV10 looks stunning...leagues ahead of any SD camera I have ever used.

Thanks. This camera sounds like the perfect fit for what I need. A highly portable camera--have to pack it on my bike for eight days--that will provide high quality footage for a small time documentary. Is it even worth it to bring a mic if I'm going to down convert? Should I just curtail my project toward a full voice over? I have senn me66. It might be nice to get some ambient noise and a few conversations outside.

Hi Matt,

downconverting has virtually no effect on the audio as long as you take care of a few technicalities. As a matter of fact, standard DV theoretically has a slightly better audio quality than HDV, although I know I would not hear the difference.

So about the microphone: of course it all depends on the content you wish to create. But as you may conclude from the above, downconverting from HDV to SD is no reason not to bring the microphone! (I personally like the DM50 because of the no-hassle click-on right out of my backpack, but I bet that that Sennheiser has better specs.)

Thanks Pieter, I'll be biking near you with it. Going to take a bike tour of the Belgian monastery breweries in May. You live in beautiful biking country. Going to order my camera now. I appreciate your help in wading with me through all the technical mumbo-jumbo. Without this site I think I'd still be out there with my twenty year old video camera wondering why everything is blurry.

Both were compressed to "60" % video quality... still look pretty good ;)
