Clips develop jagged edges during horizonal moves
I have cut a series of clips that move horizontally across the screen and as they do the edges between the outgoing and incoming clips seem to tear/band/have jagged edges. Not sure if this is some weird interlacing or banding issue that is repeated each time. I’ve modified/moved the clips using “crop” and “center”.
Has anyone seen this or have a work around for me other than going to AE?
Thanks in advance,

Are you Rendering at highest quality?
Did you try adding a bit of “Edge Feather” under the Crop settings in the Motion Tab?
Have you made sure the Vertical position of these clips is set to a whole EVEN number?

thanks for the response.
i’ve rendered at the highest quality.
i can’t use an edge filter as the seam must be hard (i tried it though and still came up with the same problem).
i have not changed the vertical position.if i toggle through the timeline and watch it on the computer monitor, i do not get the edge problem. it is only when i playback or watch it off dvd, etc.
the source footage is 720×486 photo-jpeg, i’ve tried setting my sequence setting to both 720 x486 photo-jpeg compression and dv – ntsc compression.
keep up the thoughts. thanks!!!

It might be field dominance. Try changing the setting for that in your sequence settings from lower to upper or vice versa and see what happens. It’s in Sequence > Settings > General Tab > Field Dominance.

Can you post a movie? Are you sure it’s not just normal interlacing? If you set your sequence to field order none, it’ll render progressive, but all of your other video renders will also be progressive which could be problematic if your material is interlaced. Do not change your field order to upper as it’s not right for NTSC.

i don’t think it is normal interlacing, but it may be. there shouldn’t be any problem animating images/moving picture around on the screen. but some of the shots that were shot with moves on them are getting a bit jittery also…
could the system be wonky?
-
Without seeing w an example it’s hard to know what you are looking at. I don’t think it’s the system that’s wonky, it’s a setting or a technique that is not getting you want you want. Any chance of posting a full rez example?

i’ll try and get something up for you to see in a bit.
interestingly, if i use a wipe to move the image across the screen (rather than a crop to reveal) i do not run into the problem…
