can someone tell me me my online capture settings for my varicam footage? Gary Adcock?

“Plan on about 80 mgs a second for the 720p23.98 10bit. so you are there, just BARELY.”
As a test I imported some regular ol DVCPROHD footage into AE and rendered it out at 10 bit uncompressed. Those renders were around 60, so that’s where I got that number. Actually, when I imported the clip into FCP, FCP said the data rate was 56 mb/sec. Do you get 80? Maybe I’m messing something up.
Anyway, my RAID is currently full, but I have two empty SATA drives lying around and a couple a spare slots in a box, so I figured I’d stripe em together for a speed of about 105-110 MB/sec. I just gotta capture like 15 minues, so I figured it’s be doable. Cutting it close though!
Also, the plan was to capture at 8 bit, but render a 10 bit out of after effects- post color grading and compositing in a 16 bit space.
Could you briefly explain any benfits to a 10 bit capture? I assumed 8 bit would be fine.

[jeremiah black] ” What Walter is spreading is misinformation because he says “there is no quality differnce. Recompressing to a highly lossy codec doesn’t lose information”. That is a lie and an untruth. The fact is there is an actual quality differnce, that may or may not be negligible depending on what you want and how deeply you want to care. No one ever said your worklfow is no good. Just that it’s not the best and the purist.”
OK
everyone step away from the keyboard. I am setting in the airport in NYC reading all of these posts in order and there are valid points on both sides.
Please, it does not do anyone justice to claim that any cow leader is lying is over the line. I can tell you that can handle dvcprohd in the manner that walter is suggesting without issue more than 90% of the time- I have the scopes and I can prove it, I can also show you everyplace on a waveform that it will fail. I am not using my eyes, I am using real scopes.I did the testing with both of these workflows and see both sides, part of the issue is the difference in the tool set and type of work. I have delivered content both ways- I have only had to change once do to the type of material being posted.

I apologize to everyone for allowing myself to get so upset over this matter. I was upset and I apologize.
I simply wanted to hear what Gary wrote, and what I endeavored to convey many times which is that (1) there is a difference (2) most of the time it doesn’t matter (3) but sometimes it does, in fact, matter sometimes, and might matter a great deal. (4) compression always means data loss, whether discernable to the eye or not, and scopes will prove it. (5) since it will matter sometimes, it’s a decent habit to just do it uncompressed all the time, unless your client has made it known that they don’t care or they won’t pay for it.

You’re upset? Calling me a liar, say that I’m spreading untruths, putting words in my mouth like “my way is the best way” and you’re upset?
Unbelievable. And this is truly the last word I have to say on this subject.

“You’re upset? Calling me a liar, say that I’m spreading untruths, putting words in my mouth like “my way is the best way” and you’re upset?”
Actually, I never called anyone a “liar”. I said that the position that there is no loss to recompression, and that that “no loss” can be, and allegedly has been, verified through scopes is a lie. Perhaps I should’ve chosen better words and said “is false” instead of “is a lie”. I’m am sorry for the careless word, as it conveyed a nastiness that I didn’t intend. However, and I mean nothing against your personal character and talents, if you are going to publicly contradict the facts and post incorrect reasoning, then, I’m sorry, this is spreading misinformation. I obviously assume you have ZERO motive for doing so, other than that you sincerly believe you are correct. But, I’m sorry, you are not. The uncompressed workflow is VERY valid, and produces demonstrably verifiable results when the situation arises.
And your attitude is far from angelic. You have repeadly characterized any uncompressed workflow as a waste of time and useless, refusing to acknowledge any dissent. When it was shown that there is, in fact, a use for it, you continued to push your methodology, and push it with arrogance, I might add. You hinted that I was speaking without any experince and called my personal credentials into question. You refused to concede the mathematical truth that recompression into a lossy codec will ALWAYS result in further loss of original data, and you still have yet to concede the situational validity of an uncompressed workflow- despite being contracdicted by (at present) all four other people in this thread.
“Unbelievable. And this is truly the last word I have to say on this subject.”
Yes, I’d say it’s all quite “unbelievable”, indeed. However, I again would like to close with a personal apology for reacting to what I perceived as an arrogant tone in your early writing. I have made many friends on the CC boards over the years, and I am sorry that we got off on a bad foot, and for the part that I played in it.
sincerely,
