    Posted by Rob Evans on March 8, 2009 at 1:43 am

    Hi,

    I’ve capture some Pal DV footage. The footage plays back fine before rendering on the timeline but once I decrease the speed the picture isn’t smooth – it flickers/jitters after rendering the clip! Before rendering it plays back fine at the reduced speed but the quality isn’t that good.

    Can anyone explain how I can get around this problem.

    Many thanks.

    Hi bob,

    I’ve been playing with the settings and although my footage is Pal DV, my sequnce setting were set to XDCAM! I’m not sure if I’m doing this right, but I have selected the whole timeline and adjusted the sequence settings to match my footage. Is that the correct thing to do?

    Also…

    although my footage now plays back without picture jitter on slow mo’s – I’ve noticed in the motion tabs that all my clips are set at a scale of 200. When I adjust this to 100, the picture looks fine. I think I’ve made a basic mistake, but now have a heavily edited timeline and need to make a group setting change and I’m not sure how to do that.

    I am either transferring Pal DV via a Firewire connection, transferring SVHS through a DAC 100 converter or hooking up my XDCAM HD to my system. In future, am I correct in saying I have to choose the settings to match my the fooatge I am working on?

    Are you editing Lower-first in a lower-first sequence?
    Which FC version are you using?

    hi Rob

    next time you can set an easy setup at the begining of your work that matches your format.

    also, if you are on version 6 (which you should be) when you drop the first clip in a timeline FCP will ask you if you want the timeline to match the clip or clip to match the timeline. make the timeline match and work from there.

    for now, duplicate your sequence
    change the sequence settings to this

    in the video processing tab put best on motion FX like this

    then, select all clips on your timeline.
    right click and remove attributes,

    select to remove basic motion and distort

    should put your timeline back to DV pal, might need to render, but far less than what you had to on an XDCAM timeline

    if any resizing rotating or movement was done on a clip,
    redo if simple, or copy from other sequence if keyframed and complex and just adjust the right size

    good luck

    But you must think about your delivery forma as well.
    It doesn’t make much sense to edit in HD (just because you have some HD footage) if you go to end in SD.
    Edit in XDCAM also doesn’t make much sense unless you will deliver in XDCAM or .mpg.

    Hi Rafael,

    Thanks for your help. I was fiddling and then Hector responded. I’ve followed his advice and all seems fine now. Thanks again though.

    Hi Hector,

    Thanks again for the screen prints and setting advice. I’m now having trouble with placing Live Type text on that projects timeline – the text appears jagged! I’ve tried experimenting with different settings but not having any luck.

    Also, is there an easy way to make smaller clips out of a long clip? I’ve captured 30 minutes of footage and now want to break the clip down into smaller sections.

    Any help would be appreciated,

    Regards,

    Rob
