Hello everyone, my first post here.
I've been shooting with this camera for already few months, now its time to edit. I've been FC user for already 5 years, but this project I decided to cut with Premier, as it handles the footage natively.
So here is what I can not figure out myself.
when I create a timeline in premiere and make it as 1080p AVC HD, and I put some clip on the timeline, it appears to have a red bar on top. I tried to create a sequence with automatic settings, and its seems to be ok, it has yellow bar on top. But the sequence which was created with automatic settings has upper field and is 1080i. So which settings should I go with? 1080p or 1080i? I was shooting 25P.

You should be using the preset AVCHD 1080p25 - that should work. Which version of Premiere do you have?

Hi Nodar,
The red bar simply indicates that playback performance while editing is likely to be poor, because the clip has more pixels / frames / layers / effects / whatever than your computer can comfortably handle in real time. Render the sequence to "preview" clips to be able to play it back smoothly while editing -- this is in the "Sequence" menu, IIRC, but just hitting enter with the sequence selected will do it. (It may take a while.)
Essentially when you play back a sequence with effects, layers, etc., the computer has to compute the contents of every pixel in every frame while you're playing back. This is a LOT of computation -- in your case, 51.8 million pixels per second. Up to a point this will work, but at some point playback is going to get choppy. Even without effects and layers, high-res footage can be too much for some computers. Pre-rendering to preview clips does this computation once and saves the results in temporary, lower-resolution clips which can be played back in real time -- these previews stand in as proxies for the real footage during the editing process. This does not alter the process or the results of editing, except that you pay a time penalty to render the clips, but then things are faster.
Lower-resolution footage can be played back smoothly without rendering -- that's what the yellow bar indicates. Green indicates that you rendered it. No bar (grey) indicates that it can't be rendered to anything more "lightweight" than it already is.
A faster computer, more powerful graphics card, more RAM, faster hard drive / solid state drive, can all help. There are particular graphics cards that Premiere can use to accelerate things farther. Make sure your drivers are up to date -- check the graphics card maker's web site.
Without spending money, previews help a lot. Check your sequence settings and make sure that your preview resolution is lower than the clip resolution, but something you're happy editing with -- I typically use 1280x720, but lower certainly works too. You can switch to higher-resolution previews when you're fine-tuning the edit, for example.
None of this affects the quality of the final movie in any way. You should certainly NOT shoot interlaced just to make the editing software happy!
I would normally say "read the manual", but given Adobe's documentation, I'm more than happy to forgive you.... ;-)
Hope this helps!

bkmvincent I'm using CS5.
That is what I think also, I am just confused the way Premiere decided to create sequence. It is still 1080i.

Thank you very much for your detailed post. It will definitely be useful for somebody thats starting to get interested in NLE software.
But my question was toward more specific matter that I mentioned in my first post.

Oh, I'm sorry, I misunderstood.... my bad.
If you shot 1080 @25p, that's what you should be editing with, exactly as bkmvincent says. Switching to interlaced when the footage is progressive can't be good.
But I don't get how the auto settings would give you 1080i if you were shooting 1080p.... unless it's a bug with PP handling 25p wrong??? If it thinks that the clips are interlaced, the red bar could be because of the de-interlacing it thinks it has to do...? I'm shooting 29.97p and not seeing this.
If for some reason PP is mis-interpreting the footage then you can override PP's default interpretation. Right-click a clip, or multiple selected clips, and select "Modify" -> "Interpret Footage...". Then under "Field order" select "Conform to: Progressive". I'd be interested to see in this dialog what it says the original field order is -- that could give you a clue as to where the problem is.
Hope THAT helps... ;-)

You weren't by any chance using Smooth Slow mode?
