    Please help with a gap in my understanding

    Probelm. - My H264 export has some footage with saw tooth comb like jagged edges on movement.

    I unmderstand that this is a field order isse. But what I dont get is that, as this is for web, I made the HD sequence in AVID Progressive. The footage, although interlaced (and therefore containing 2 fields) was never imported. Merely accessed by AMA. Its is the import dialog box where i understand I need to address field order issues on import, but there was no import, only AMA link.

    So how can i have this issue. Is there somewhere in th eexport dial that ive incorrectly set. Or should i be applying a filter??

    Thanks in advance for any pointers

    Well, one thing you can do is apply the Timewarp effect on your clips (or perhaps a seperate video track on top? ). That by default will make your output progressive.

    HI Grigoris

    Thanks for that.

    Does the timewarp effect have any setrting in it. ie  do i drop a field, or combine the 2 fields , blend etc etc.

    If the source footage has issues, I might still see it Id have thought.

    Its a pain that i dont see this on my AVID monitors. Is there a way of making avid play both fields of a seq so you can see the issue before you export it.

    Yes, you can choose "Type" (where you choose what fields are seen from what I gather looking at it right now, and can also choose your "source" type and "output" type.

    EDIT: that is for the Timewarp effect, I suppose if you choose the right settings, you will see them on your Record monitor...

    Re: Please help with a gap in my understanding

    To correct field order errors (or at least mask them) with the timewarp effect, choose "blended interpolated" for the type, source: interlaced, output: progressive.

    With AMA sources you can right click and choose set source settings and in there set the field order option.

    If you set that right the clips in the timeline will get a green dot (after you refresh the sequence with source side settings) And that green dot will do the interlaced to progressive conversion which you can promote if you want more control.

    Re: Please help with a gap in my understanding

    HI again

    How do i best apply the timewarp filter?

    I couldnt apply it to a blany upper track (effect does not apply)

    I coulnt apply it to a track that had a cc effect on or asa  nested effect ( (effect does not apply))

    In the end i had to make a video mixdown and apply it to that. Im rendering it now

    How would you guys get it on there.

     

    Pat

    Can you clarify your ama sesstings message. I looked for what you explained but found nothing (although ALL my timeline clips did already have a green dot on them.

    Peter Groom:

    Correct, because timewarp is a "motion control" effect that must be placed on a master clip with footage, never on a blank filler track or clip.

    Peter Groom:
    I coulnt apply it to a track that had a cc effect on or asa  nested effect ( (effect does not apply))

    Because a timewarp effect or a motion control clip MUST be applied on the clip at the very bottom of any effects nest. You CANNOT apply a timewarp effect on top of any other effect, or step into a timewarp effect to place another effect underneath of it. Same restriction applies to a motion clip created in the source window.

    Hi again

    So how do you apply the effect if you have a timeline with hundreds of clips?

    Individually?

    In the case of a nest of effects, yes. In the case of standard clips with no effects yet, create the effect once, then drag the effect icon from the effect editor to a bin. Now, segment select all remaining standard clips and CTRL double click the effect icon in the bin.

    AMA clips should have a right clip option (or under clip menu) called Set Source Settngs. For soem AMA content Avid assumes this is fixed and the option will be greyed out (unhelpfully if the content is actually wrong as it can be)
