24p timeline advantage

Hey cats,

I shoot at 24p on the dvx and edit on vegas on a 60i timeline. My final results are always great. I don't output to film, just to DVDA and make DVDs to play on my TV.
And it all has the film look of 24p.

Yet, it seems that so many of you edit on the 24p timeline. I can't figure out what the advantage would be. Am I missing a great opportunity here?

Thanks

Yes.
Editing on a 24p timeline allows you to make an actual 24p DVD, compatable with progressive scan monitors and computers.
24p DVD's also allow 20% more content than their 60i equivalent.
Vegas has such great 24p timeline features, it is truely a shame not to take advantage of them.
 
The 24p timeline has several advantages.

First, you can output 24p DVDs. No interlacing ever enters the picture, and those DVDs can be played back on progressive-scan DVD players to LCD or plasma type televisions, in all their progressive glory. Or, you can play it back on a computer DVD player and see full progressive footage.

Second, you can fit more footage on a disk (20% more) using the same compression ratio, or you could fit the same amount of footage but use a milder compression ratio.

Third, rotoscoping would be a lot easier on 24 progressive frames per second than it would be on 3:2 60i footage.

I'm sure there are other advantages that I'm not thinking of right now...
 
Wow. I really am a boob. I had no idea. What about a 24p DVD playing on a non progressive DVD player and an old fashioned interlaced CRT TV. Would it work on all those devices?

You guys are great!

Yes it would work on those devices. All DVD players have the ability to add 3:2 pulldown to make 24p footage compatible with 60i interlaced televisions.
 
Barry you copied me, again. I'm sick of you always making yourself look smart by copying my posts. And then there is that damn book. I was looking through that book and DVD, and I swear you broke into my computer and stole all my test footage, notes and otherwise award winning work.
When is everybody going to figure out that I am the master mind, not Barry Green!
AAAAAAAAAAARRRRRRRRRRRGGGGGGGGGGGGGG.















:evil: :grin: :huh:
 
Doh! I totally did copy your post, didn't I? Seriously, you posted inbetween when I started and when I finished... I open up all the "new message" windows at once, then go through them one by one, so by the time I get to responding to the first one opened, it might be 20 or 30 minutes later... and, as usual, I took 3x as many words to say the same thing someone else can say much more concisely! People post so quickly around here, I have to remmeber to "refresh" before posting a response because usually one of our knowledgeable members will have gotten to the question before I do... sorry 'bout jumpin' your post, you had it well in hand!
 
This might be a bit of a newbie question but if i edit footage shot in 24p on a 24p timeline can I still output the final project to tape (VHS)? Or can it only exist on DVD/progressive ready player. Does Vegas insert the pulldown to get it to 60i? Thanks a lot!

No. Insert 2:3:3:2 pulldown if you plan to do more editing what you export (e.g., sending it to someone else for editing). Otherwise, isert 2:3 pulldown.
 
Thank you for the answer. But what is differ on physic level?
Another stuff, which deeply harm me. Perhaps It's ok, but I am very doubted guy.
I did shot in 24p, I have captured via Vegas it onto computer.
In Vegas's explorer when I click on this file I see: 720x480x24 23.97fps, which looks ok.
Then I did a render as 24p with inserting 2-3(or 2-3-3-2) pulldown.
In Vegas's explorer when I click on this new file I see: 720x480x24 23.97fps, which looks ok as well.
My worries:
1. Within preview I see some strange pixelation within an edges, like interlacing...
2. When I do rightClick on these files I have got: 720x480 29.97fps
3. When I use for this purpose e.g. VirtualDubMode, or Ghost, or VideoScoop I have got 720x480 29.97fps.
My questions are: does it should be? How I can make sure and even double check if it really is 24p?

Thanks a lot for any advises!
Alex.
 
No, I have checked it - I am in 24p project!
I am just wondering if I did not do something special when I did shot...
Perhaps I will post my pictures to show what it actually is...
 
Well, first, you don’t need to use VirtualDub or any other third-party capture program. Just use Vegas’s capture and you will be fine. Vegas will remove pulldown to edit in native 24p when necessary, and leave it in place if you want to edit in 60i. It’s the least hassle possible and I suggest you do it that way. Vegas is not like other NLEs which require a special capture of 24p footage. Just capture, then drop onto the timeline.

Whatever the issue is (and not being familiar with how VirtualDub pumps out files), it’s not because you did something wrong when you were shooting. If you shot in 24p, then the footage will be 24p.

Please do post the photos.
 
Ok, thank you!
I'll do post the photos later today, when I'll get a home.
Now just a note: I am not using V.Dub in the capturing at all, just I have used it for checking of the parameters that file has...
Meantime, if in the Vegas I will save the 24p rendered file, why it is still interlaced.
What kind of third-party tools I can use to check the parameters of any video files?

Once again, Thanks
 
That's not interlacing. That's just the limits of DV -- its resolution and its color space.

Apply a chroma blur effect to it -- it should help. It will slow your playback down, but it will help smooth that out.
 
ahh...the awesomeness and wide varieties of colors that our good friend Mini DV tapes gives us all....freaking bitches....why cant it be better?!?!?!!? baaahhh
