    Acording to the item properties you have posted the clip has field dominance set to upper field, which indicates an interlaced file, and your sequence setting show an interlaced timeline with a matching upper field dominance.

    Thanks MtD de-interlacing sorted the tearing issue ... I didn't shoot the footage but had assumed that 25fps was progressive rather than interlaced by default - is this not necessarily always the case then ?

    Well, I am not sure what your workflow was to ingest the source camera clips into the system. But the two screen shots you posted indicated an interlaced source on an interlaced timeline.

     

    25p is progressive. Some video cameras will record a supposed "progressive appearing" image, but in an interlaced format.

     

    Do you know what the original camera was, and what the settings were on the camera when the clips werre made?

     

    How where those clips taken off the camera media and ingested into FCP?

    It was a Canon 5d mk 2. I was advised by the camera op to convert the native QT H 264 files to Apple Pro Res but I don't know much more other than he shot 25 fps. I'd be interested in any thoughts but you have resolved my main issue re. the tearing. Many thanks, peter

    That is correct, you need to convert the native camera files from H.264 to ProRes. How did you do this?

    I have seen cases where a converted file will be flagged with field dominance even though it is a progressive file. If you used a converted file that was incorrectly flagged as the first clip on an FCP timeline, and FCP prompted you to match your sequence to your source clip and you did so, you may be unnecessarily editing on an interlaced timeline.

    Interestng. Thanks. I do a lot of H264 to Prores. Something new to keep in mind.

    I used Mpeg Streamclip, so it sounds as though I may not have paid enough attention to my settings there ... thanks
