Deinterlacing

Haven't worked with interlaced footage for a little while so maybe I'm missing something. I'm editing in premiere 5.5. I have footage shot at 60i upper field. I edit in an upper field timeline and then nest it in a progressive sequence in order to export for web. Even though I'm exporting from a progressive sequence I still get interlace artifacts on my exported video. There is no deinterlace button in AME and the field option button is grayed out for nested sequences. The only way I've found I can properly deinterlace the video is to go to the original clip in my original timeline and deinterlace in the field options. This is fine, however, I hate having to do this for every single cut I made in the video. Is there any way around this? I'm exporting as an h264 mp4. Thanks!
 
That hasn't been working, I've been getting interlaced artifacts that way. The only solution that has worked for me was to export the entire sequence as an uncompressed avi and then reimport it, select deinterlace in the field options (this way I can select it for the whole clip rather than each clip individually) and then export my h264 file.
 
If it's not working, I'd suggest you're doing something wrong somewhere. Done right, the process works just fine.

What model camera is the footage from?
 
the footage was shot on a canon xh-a1. captured and imported into an interlaced 1080P sequence. The file properties say upper field. For some reason it just won't export without inerlace artifacts unless I manually go into each clip and deinterlace. Interpreting the clips in the project window as progressive doesn't work either. I can't wrap my head around why. Either way, for my sanity I might just chalk it up to a glitch with premiere 5.5...I think I can live with that considering I so rarely shoot interlaced these days.
 
I have a A1 and always put the footage in a matching sequence, in this case that would be 1080i25/30.
For web i used to choose the youtube preset or a hdtv preset.
No interlaced artifacts.
 
I have the same results as Ann, albeit from a different camera.

1080i footage goes into a matching sequence, exported as progressive for web playback and no artifacts.

Can you link to an example of the artifacts you're seeing?
