bought dvx and unhappy

canon uses a 6gop Structure. ITs much better than the Sony 12GOP. You probably wont be disapointed with the canon. I almost bought it, but got the HVX instead be cause the HVX is FAR more flexible and User controlable as to its recording capabilities.

Canon uses the same 15-frame GOP as Sony uses. They use 12-frame in PAL territories.

It's JVC that uses the 6-GOP structure, but only in 24p/30p; I think it goes to 12-frame GOP in the new 60p version.

hdv doesnt ghost. it macroblocks and has a 6 frame stick on very slow moving details, like grass and leaves on trees.

Well, again, depends on the flavor and on how hard it's being tasked. JVC HDV that we shot through the mini35, at night, exhibits extreme ghosting.

The XHA1 can also show substantial ghosting if you use the NR1 function. Not sure about NR2, but NR1 can cause ghosting.

yes, i think, there are two reasons for ghosting:
when aktivated noise reduction
because of the mpeg2 hdv codec, its a infraframe codec

i would like to hear about the last point, that would be great.
real life experiments on fast movements in hdv (at postpro)

thanks

I'm just thinking that your clients wanting HD will pay a premium price for it, but some clients may not want to pay for HD and will be satisfied with SD at a lower rate. However, the decision should be based on the demand for work in your area and your own finances.

Good luck with your decision. :thumbsup:

thanks. because the canon xha1 costs nearly the same as pana dvx100, i am asking here for pros and cons and the intra/infraframe thing of ghosting, wich could be awful in postpro. anyone?
regards

You will only see ghosting on the A1 when the NR1 (noise reduction 1) function is used. I never use it, and never see ghosting.
 
thank you very much for reply.

i have read, that the infraframe codec of hdv can produce a ghosting.
is it not true?

regards

you are right, when the client is asking for hd, he or she have to get hd for a higher price, of cause.
mostly, the clients want a dvd. this means sd in the produkt in the end. but looking at the camera asking, is it hd, hd is better and i have to explain.
thanks

If they want their product on a DVD and are not able to understand that DVD's do not support an HD format than I would tell them to go somewhere else. If you need to, tell them that the camera you use was also used to shoot movies like "A Scanner Darkly" "28 Days Later" "Murderball", etc. If that doesnt convince them to go with your service, then they wont be happy anywhere else they go.



I still think HD is overrated as of now, I will wait until more households have HDTV's before I switch. Hell, Im still saving up for my own 100B which I wont be getting till March.
 
I think you need to go with an HDV camera if it's going to get you work. Clients frequently have irrational requests, but since they're paying the bills, it's up to you to have the gear that they're looking for. Yes HD is just a buzzword if they want an SD deliverable, but they want to hear the magic word--HD. The idea of educating clients is good in theory and may work sometimes, but often, the client has an idea and you're not going to change it.

Sell the DVX and buy an A1, so you can compete in your market. I'm no big fan of interframe compression codecs, but they're fine *if* used within their limitations. If HDV gets you more work, then you should be able to trade up to an HVX pretty quickly.

maybe i should work with the dvx until i have the money to buy a hvx (?).
because i have to use the cam for my art-work in the first line, i worry about the infraframe mpeg2 codec in situations of very fast movements in the picture.

for my clients, i worry also for the mpeg2 codec. live events, theater and performance i cannot shoot again. when there is a hdv dropout, it lasts for about half a second, this could destroy the work.

do i think about it in the right way?

thanx and regards

...but to fill the 16:9 issue would be great-for my clients and for me :)

what do you think is "better" a 16:9 linse or a uprez in post?

Oh really?

Shoot Wrong again.... Ive read so much on these HD cams they al kinda blur in to one.....

But i didnt know that the HDV cameras ghosted i thought it was just macroblocking. If its from the JVC couldnt it be that "smooth" motion thing?
 
Tim the A1 ghosts only when the NR1 function is engaged. Now without the NR1 the lowlight is comparable to the HVX.
 
Ahh. well i mean i could put a Dynamic noise resucer on HVX footage too. but hten it ghosts.... lol
