My Canon HV20 vs. JVC GZ-HD7 experience

That was not the code I was emailed, and I actually received two emails because they have me on file under two email addresses. Each of the two emails came with two different codes. Because of this I assumed they were one-time codes. Doesn't really matter though because the deal ends today.

Hello, Guys!

I hereby post some clips which I have taken with JVC GZHD7, I would appreciate suggestion & feedback from everybody.

The first clip I have give name “New York Street Dancer” it was huge in size but I compress it and made 500MB in size. I have not done anything with the clip but just converted it in 720p.

The second clip I gave name “Jockey”, my dog, “The Great Dan”. The clip is as it is 1080i.

The third clip I gave name “Monkey” I was on my terrace and I saw some monkeys on the tree and I captured them in my camera, they were too far from me, so I used full zoom almost 10X. I convert this clip in 720p and put music.

And a fourth clip is again same “New York Street Dancer” with some extra music, and I did some post video enhancement with “PowerDirector”. So please try to compare both “New York Street Dancer”. This clip is not HD 720p but I converted it in DVDHQ 1280x720p. If we compare both then clearly HD720p looks very sharp.

Highly appreciate views/feedback and suggestion from everybody, and please be patient all clips are huge in size.

Waiting for feedback/views and suggestion.

Thanks,
Kaushik

P.S.: Some times the traffic is m uch so please keep try and you will able to download.

I think I found a way to minimize blocking artifacts in HDV blacks. I would like to explain and if someone try it, let me know.

1 - put the same m2t footage aligned in two video tracks in Adobe Premiere.

2 - in the upper track apply gaussian blur and adjust between 4 and 6. (adjust looking the blacks)

3 - in the upper track apply arbitrary map and adjust between -5 and -1 (adjust looking the blacks)

4 - in the upper track apply luminance key (adjust the key to keep only the blacks of the upper track over the lower track, be carefull to not get color fringing in key edges)

5 - render to uncompressed.

The goal is to minimize the blocking artifacts in the blacks where HDV compression is more visible.

If someone try this, let me know.

Thanks.
