Hi People,

in the next few weeks i have to film two documentals,

1st is a 50th year aniversary of a catolic school, 2nd a "tango dance documentary".

For the first one, dont have any issues in particular, but the budget cant afford a full 1080 AVC-Intra 100 Post. So i suggested to the people to do it in 1080i in DVCPro Hd. But my problem is that i don´t know what minimun computers hardware requirement is needed so i can work with no problems.

for the second one it will be filmed with a lot of contrast, I would like to know what type of Gamma curv or other file scene do you recomend me for this case.

Thanks in advance

Any system that will edit AVC-Intra 100 will easily edit DVCPRO-HD. Both are 100 mbit, intra-frame formats. Maybe you should try AVC-Intra 50 or maybe even DVCPRO 50. What's your output? DVD? Unless your going to Blu Ray or HD web, HD is not a necessity (even though it does look nice). ;)

For the gamma, experiment with the different cinelike gamma settings. Those will give you the best contrast and dynamic range.
 
I even though it was the reverse namely any system that can edit DVCpro-HD can edit AVC-I because the letter is less compressed (less processor speed needed). Only thing is that AVC-I needs more data storage. He but maybe I am wrong

AVC-I is going to be better quality but requires more storage, power, and RAM.


AVC-I 100: 1920x1080, 100mbit Intraframe, 10 bit, 4:2:2. 4.1:1 compression ratio

DVCPRO-HD: 1280x1080 (for 1080i/p) or 960x720 (for 720p), 40-100mbit, 8 or 10 bit 4:2:2. 6.7:1 compression ratio


The lower compression ratio and increase in pixel count will take longer to render and edit. I still think that if your not going to an HD format, HD is not a necessity. If you really feel compelled, you can try 720pN DVCPRO-HD to save space but still have the quality to do what you want.

Whenever I do a project, I sit down with the person who hired me to see what they want. If they want 1080p, I'll give them 1080p for a cost. I try to get them to understand that they may not need 1080p and that 720p or even 480p will work for them. Its not going to hurt to have the extra quality, but just think of how much more efficiently things could be if you don't have to waste time rendering AVC-Intra footage.

Hi thanks for the data

i will follow your avice, i just sit with the client and show him the diferent alternatives, then he can choose, Also i can let him know the pros and the contra of shooting in each format.

Thank you
:cheesy:
 
Damian, unless you quantify stuff by cost reflecting storage and extra render time, your client will immediately go for AVC-I 100 @1080! Have those P2 cards standing by!!!
