Hi Jay. I don't think the section in the Canon manual is written with DVD in mind, so when you mention DVD, you are no longer quoting from the Canon manual. There are good reasons (very well explained in this thread) for using Advanced mode if you are going to TV via 24p timeline and DVD, so your statement is not really very accurate after all.

Ding, ding, ding! Josh wins the first lightening round with the 'most correct' of many 'correct' answers. What do we have for Josh today?

We have a lovely assortment of spam, lens cleaning wool, and 5 lbs of pan motion grease.

It's also funny cause your name is Pat, and many-a gameshow host is named Pat...



What do we have for them Pat?!

Abou the shutter speed? 1/48 is standard film shutter speed (1/48th of a second, 24 frames a second... 24x2=48) however, if you use a shorter shutter spee dyou can acheive the gladiator (stutter) effect of no motion blur. I think it looks cool.

Zia,

Sorry to be so flip in my response...it was LATE. I'll see if I can actually help you now instead of just having sport with the response from another forum member (and Josh, no offense intended, you we thinking the same thing I was: 1/48th).

Here is a DV Info article discussing the topic: Achieving a Filmlook with Digital Video

And Sony has a good description of 24p in a Whitepaper, obviously slanted toward use of 24p in their product: 24p.pdf

Oh Pat, No offense was intended. Sorry I was also quite tired and I thought your response was humourus.

Ok so heres a question. I shot in 2:3 and have been editing in vegas in a 24p timeline. I now want to render it down to a new avi. What should I use 2:3 or 2:3:3:2? I then will go to mpeg for DVD.

Also, if I stay 2:3 which apparently eats up more space...how much are we talking here? At this ponit Iv learned my lesson and will always shoot 2:3:3:2 from now on but what is best for my project at hand as far as best quality?

thanks!

If you're staying in the 24p realm, stick with 2:3:3:2.

Rendering out to 2:3 causes the frames to need to be uncompressed and split and then re-compressed. Rendering out 2:3:3:2 causes the frames to be directly copied with no uncompression.

2:3:3:2 is really superior for just about any purpose, except for editing on a 60i timeline. However, neither version takes up more space, they take up exactly the same amount of space. But 2:3:3:2 is optimized for 24p extraction and 24p editing.

So 2:3:3:2 even though I shot it all at 2:3 on my XL2? Also, this is a side question. Does anyone know what the DVX100s use. Not the A's the first modle. The shoot Ive been editing is with 3 dvx and one xl2.

Thanks again all. Id be dead in the water with out this site.
