    How do pro editors usually deal with 30p phone footage in PAL world ?

    When including footage from a phone (usually 30p) in a project in the PAL side of the world (25p or 25i) - and this is becoming more and more common I reckon, in certain types of projects at least-, I found that the default motion adapter (120%) results in irregular pan or other movement rendering (brute force frame skipping), while fluidmotion requires sometimes astronomic render times and often manual fine tuning of vectors (depending on scene content).
    So I wonder how pro editors deal with this ? Or is it so that in some cases (broadcast), hardware framerate conversion tools are used instead ? Just curious...

    I mostly use phone footage at 25fps in a 25 fps project and accept the slight slow mo.

    The jumps are more likely to be due to the variable frame rate that the phone captures at.  Depending on how eratic the frame rate is there may be no practical way to get rid of that problem.  However when I've had to do this in the past I've set up a batch job using slowmoVideo on a spare PC.  Alternatively, if it's only a few I've used AE to change the speed.  Haven't had to do it recently though.

    I also recall once importing 30 fps media into an AE project and exporting it as 24, then dealing with the 24 fps media as 25 with a fair degree of success.  In that case we had to integrate a bunch of establishers shot at 30 fps in LA into a local 25 fps project.  I don't recall the full details, I just know that we got it to work, but that it was a pain to do.  Because there was no sync to worry about, in the end it worked really well.

    Of course all the above totally ignores the sound.  That's a whole new ballgame.

    Experimenting a bit more and because most 'brute force' 120% MA visual problems occur during camera panning, I found that applying a stabilizer ("smooth") effect (on top of the 120% MA with "Duplicated Field") yields better results; depending on the scene content (rolling shutter jello effect and/or rotational shake), either the BCC or the MC stabilizer gives better control or results. The MC filter will add field interpolation if it's a 50i project, which adds nice smoothness when there is panning while the BCC filter does a better job in sharpness control or when there is rotational shake.

    Also, setting the MA to "both fields" (in: progressive, out:interlaced) gives very slightly better results

    So for me, when using 30p phone footage in a 50i project and speed may not be changed for some reason, the best way to go is to:

    1) apply a 120% MA (default) with "both fields"

    2) add a stabilize effect (MC or BCC) with short-range smoothing value (e.g. 10 frames)

    In case this would help someone....
