    My friend and I both work together on various video projects. We deliver all of our media as standard dvds. He insists on shooting in HD though and swears the video quality is better than regular DV, even though he is downconverting. Any truth to this?

    Probably. The quality of the end product is always related to the quality of the source material.

    Absolutely. Just like audio there are nuances in the recorded material that are there when recorded at higher Quality.

    Now, If you are going to keep it in a DVD format throughout, it'll save you time and space to just recorded it in the same resolution as the end result.

    Me personally, I record at a higher resolution then downconvert.

    Well, if conversion can be avoided, I'd say avoid it.
    However, if you have to capture/record in either DV or HD, and want to author to DVD, you have to convert anyway, so go ahead and capture as good as you can.

    Details will help

    What camcorder model?
    What method to downconvert?

    Basic rule is quality out is a function of quality in. But there are subtle issues in conversion.

    It all depends. If the video equipment you are using to shoot in SD is reference quality and the absolue pinnacle of what SD video is capable of, then shooting in HD will do little for you if you downconvert to SD anyway.

    But since you are most likely not using the absolute best, shooting in HD and downconverting will most certainly give you better quality.

    Thanks for the replies.

    I'm using the Sony HC-1 in conjunction with Sony Vegas. I then transfer the video to my vaio using firewire. The HC-1 allows me to either shoot in HD, where it will then downconvert (I usually set this option if I try the HD since I figure I wont be burning HD video to a dvd), or I can just choose to shoot in DV. I figured since it's all going to end up as DV eventually, might as well just shoot in DV mode and save the space. But now I'm rethinking that, since you guys are saying there would still be a difference.

    Thanks again.

    With that camera you have a HDV master on tape (save it for the furure) and can downconvert in hardware for DV editing and DVD authoring. Sort of best of both worlds in capability.

    Depends how much editing you are going to do.

    HDV is MPEG2 and the down converted DV will contain video frames recreated from the partial B and P frames in the MPEG2 stream. If you are doing any complex editing or even simple cuts that do not occur at the I frame (every 6 typically for NTSC HDV), the degradation may be worse than shooting in native DV.

    HDV does not equal HD!!!!

    If you had a true HD recording, I would agree.

    The issue is that, to the human observer watching an HDV video playing back at full speed, everything looks fantastic. But look at each individual frame separately and, if you can see the blocky artifacts of the MPEG2 motion compensation, that will likely cause problems in editing. So, in part, it also depends on the quality of the MPEG2 compression in the camcorder.
