Losing Resolution

I'm working on a project shot in HDV with a Canon HV40. The project is completed and looks good in the Timeline. All the video is on an external drive.

I did a couple of quick freeze fames during a camera flash, and I was happy with the result. The freeze frames look sharp and the they hold without any jitters.

I copied a portion of the video and pasted it into a new Sequence that I created within the same project. The problem is that the video is now less sharp and the freeze frames that look good in the original sequence are now jittery and have horizontal stripes of alternating resolution.

How can I copy and paste video that will maintain the original quality? Is this happening because I worked with tape?

Please give the exact item properties of the clips you're copying and the exact item properties of the sequence into which you're pasting them.

Hi,
hit Command+zero to check Sequence settings of both sequences,
they don't quite match, do they?
Settings have to match

Also take a trip down google lane with the term "interlaced video"...

Hi -
Just a guess, but is your original sequence (where you made the freeze frames) canvas set to something other than 100% viewing area?
And the new sequence, where you see the jittery key frames, has the canvas set to 100%?

You will only see the effect of interlacing when the canvas is set to 100%, I would wager if you return to your first sequence and set the canvas to view at 100% you will see the same jittery still frames.

The solution is to either choose video source freeze frames that contain no motion in them, or if that is not possible, go to the Effects Tab > Video Filters > Video > De-Interlace and apply the De-Interlace filter to the freeze frames on the timeline.

Hope this helps.

The original clips are 29.97 fps, 1440 x 1080, HDV 1080i60, Data Rate- 3.2 MB/sec., Field Dominance- Upper (Odd)

The properties for the copied clips are the same. The freeze frame clips are also the same.

I should also mention that the original video is part of a Multiclip sequence.

You are correct. The Canvas in the original sequence is at 44 precent and the copied version is set to 100 percent. That's not something I have ever even paid attention to.

One more point: I'm now working on another version of this project. I've already burned both Blu-ray and DVD versions. The Blu-ray version was perfect. The DVD version showed the interlacing problem on the freeze frames.

I'll try your suggested solution. The version I'm working on now is for YouTube.
