Very strange motion lines, look!
Hey guys, im in dire need of some help here. I shot a lot of footage using a Canon Legria HFS100, but, for an unknown reason when i logged and transferred the footage these lines appear in the browser whenever there is any motion in the image.
The item properties of the clip, according to FCP, are as follows:
25 fps
440×1080
compressor: Apple ProRes 422
With everything else as it always is for a clip.
My A/V settings are just DV PAL 48 kHz, set to 25 fps as well.
Could it be a problem with interlacing or something similar?
Any help would be very much appreciated.
Thanks! Dan

Could be, but you left out any information regarding your sequence settings. What does Field Dominance say in Sequence>>Settings?
Also, if you set your canvas size to 100 you may see the interlace disappear.

It certainly looks like an interlacing issue. I’ve seen similar issues when scaling interlaced footage. Double check your footage resolution and make sure the sequence you’re editing in matches. Your footage is HD, but you’re editing in an SD timeline? Is that right?

440 x 1080?
Should that be 1440 x 1080? Which is some kind of HD or HDV size.In which case why are your sequences DV PAL which is an SD 720 x 576 size.

Ah yes, sorry, that should be 1440x 1080
Thanks for the help guys, im not sure what it was exactly, but changing field dominance to odds or evens, instead of none, seemed to help.
Rafael, I tried changing to a sequence preset that was designed for i50, but that did not seem to help on its own :S
But anyway, thank you folks!

Hi Daniel,
Is not the sequence preset what you have to change.
Make sure that the stuff shows as “Upper-first” on the Browser; then try on an Upper-first sequence.

Daniel,
This is not a guessing game, it’s science. I responded to your initial question first by asking you a very specific question, which you still have never answered. It would have clarified this completely.
So, please go to Sequence>>Settings and look at Field Dominance and tell me what it says.
For the record, all interlaced HD is Upper Field dominant.

Sorry David, I thought I had responded properly, but I guess I wasn’t very clear.
I looked at Field Dominance and it simply said ‘None’.
I experimented by changing it to Upper, and this seemed to get rid of the lines.
Thanks for the on-going support.

Bingo!!! As I suspected all along Daniel. This is because, as I mentioned earlier, all interlaced HD is Upper field dominant. So, now you know the science, and that putting interlaced material on a progressive or “none” timeline looks like doggie doo.
BTW, a little know fact is that, putting progressive material on an interlaced timeline actually looks just fine most of the time. That’s a well-kept secret, so commit it to memory.

Hi guys, I’ve been having the same issues with a canon vixia, when i started using it last year, everything was normal, i could log and transfer from FCP, now i can’t so i had to get Voltaic for encoding the MTS to AppleProRes, but then i started having the same lines you’re are showing, don’t know what i’ve done wrong, if it’s the camera or something on the workflow i’m missing.
Can anybody tell me what’s going on with fcp 7.0.3, and do u know if fcpx will accept all the codec without rendering????
BTW finally i get rid of those lines using the de-interlace filter on (Flicker filter minimal or medium) and runs great and also using Smooth cam is a great solution when u have shaky image and the lines.
THX!
