Here is one way to be sure your sequence is right so you don't have to make changes

Just out of curiosity, if the footage does not look right, what would be the purpose of changing the Sequences' settings?

If, for instance, you created a DV seq and put HD material in it - FC would resize the material to DV size, when you changed the seq setting to HD the clip would be too small, you could then remove the resizing so it would display properly. It would ususally be easer to create a new seq and copy and paste into it, same as Premeir.

What type of camera did you record your AVCHD footage on? The reason I ask is because I'm thinking the most likely reason it thought your video was interlaced is because several AVCHD camera's shoot footage that they call "1080p" but it's not actually normal progressive footage. It's actually PsF footage. (Progressive segmented frame)  Which with this footage it just records both fields, so what ends up happening is that Premiere ends up reading the footage like it's interlaced which it basically is, except unlike normal interlaced footage this PsF has both fields. Anyways though you can find out if this is the case by using the modify>interpet option from inside your bin, then if it says that you files field order is anything besides progressive then you'll know you will need to conform the footage to progressive as explained in this article in order to make Premiere work with it properly. Although this issue might not be the same thing you're experincing I just figured I'd mention that since it's fairly common place for AVCHD cameras to record PsF.

You may want to check out this article although it may not apply to you depending on what type of camera you're using. Although they cover basically all the major AVCHD camera makers

They talk about several Cannon, Panasonic and Sony avchd cameras that all currently record footage this way.

Hopefully at some point camera makers will start being a little bit more up front with this information. I actually ran into quite a big headache awhile ago when I got some footage from a client and it drove me nuts that Sony didn't disclose all the facts and they simply list it as 1080p even though no edit programs are going to see it as 1080p... I remember I kept wondering why my finished product didn't look crisp and clear and instead looked "jagged" and "blurry" then I came accross the pro video articles that explained what was going on. I find it silly that the camera makers can't simply list the fact it's PsF and also the fact that both Final Cut and Premiere will see it as interlaced somewhere in their manuals...

Although quite a few AVCHD cams shoot in PsF so I guess they might be figuring we should just know. But still I think it's silly.

But that's just my personal hope. However until then I'm glad you now have a proper work-around.

Well yes but only if the sequence is empty.

I emptied my sequence still could not make the changes. Does it also have to not be used anywhere as a nested timeline?

Yes. I am a Creative Cloud subscriber.

I tried your workflow and could change the settings.

So you had raw footage (RF) that you put on a sequence (A) that you put on a sequence (B). You then cut the footage from the sequence (A) and saved, then changed the sequence (A) settings?

Sequence (B)

     ^--Sequence (A)

          ^--Raw Footage (RF)

If you did and it worked then either I am doing something wrong, and that is more than likely, or there is something else that affects the ability to change the sequence settings.

Hello Bill

How does that help. I have already used the footage in a sequence that I have placed in another sequence and edited the footage.

I had raw footage (RF) that I put on a sequence (A) then I placed that on a new sequence (B). I then edited the footage (sequence (A)) in sequence (B).

Sequence (B) - edited for content here

     ^--Sequence (A)

          ^--Raw Footage (RF)

I dont know if this is the best method of doing things but I figure it will allow me to put effects and stuff on the whole edited sequence after I am done editing without having to do it for each bit. This is a project that is around 30 minutes in length of footage. I am trying to trim down to a 5 minute presentation and I do need to also create a DVD of the full 30 minutes.

A feature request would be for Adobe to make any and all AVCHD footage recognized properly.

In that case, no.

 

But you can create a new one with the desired settings and Copy/Paste clips into it.

In 5.5 I did noticed the handles on clips were sometimes lost when copying and pasting clips into a new sequence, in that you can't change the in and out points to extend the duration as you could in the original sequence. What I did was copy and paste the entire clip then set the in and out point in the final sequence. I hope that has been fixed in 6.0.
