  • Crop and Feather tracking issues????

    Posted by Oliver Michaels on September 29, 2011 at 8:56 pm

    Can anyone help me understand what is happening and if there is anything i can do about it..?

    I’m finding fcpx’s lack of under the hood controls astonishing and frustrating. i am using the crop and feather effect (as there is no feather in trim) to create a wipe between two shots. i am trying join two panning shots together, using a dark space in the frame as a point to track on, so that the shots appear to be one continuous pan.. (hope this makes sense)

    so i mark a number of keyframes as references as i would do with the trim tool or old crop tool. but when i play it back the crop line moves erratically as if fcp is trying to anticipate something/create a smooth movement i do not need(?), it’s like it is slowing down a touch before each key frame or something?? the end result is that the line does not follow a linier path..

    any help would be much appreciated…

    I don’t think can do what you want. All keyframes are eased. The crop wipe would have to be a continuous motion, with a pair of keyframes. Sounds like you need to use Motion for this.

    All the best,

    Thanks for your reply Tom,

    eased, it seems crazy to control a movement and not give us any way of turning the feature off… i’d understand it in imovie but not in a pro app.. it makes everything so limiting.

    i don’t know how to use motion.. guess im about to find out.

    so does every keyframe in every movement effect use easing?

    Hi Oliver

    I’ve revised my Adjustable Frame Effect to be able to give you a crop and feather tool with quite a lot of control flexibility.

    3009_tkyadjustableframev4.zip

    Using the Mask X and Y Position controls you can adjust the “crop”, which you can also feather using the Feather and Fall-off controls. There is also a Shear X/Y option to give an angle on the edge.

    Note that the effect will also give you the ability to move/resize your source image, as well as move/resize the cropped image. There are controls for corner roundness of the mask, as well as border and background on/off.

    To do the task you are trying to do, you will want to apply the Effect to a connected clip (the incoming clip) above the outgoing clip and animate as appropriate.

    However, its the animation part that is not possible to achieve in the current versions of FCPX/Motion 5. All FCPX keyframes are ease in/out and there’s nothing you can do about it.

    There is a canny work-around that can create a linear move between two points – but more than two points and you will again come unstuck. Very tiresome – I had hoped they would look at this in 10.0.1 as it’s a pretty basic thing but no such luck.

    I’ve created an effect that works in the same way cropping worked in FCP7 – the same way as the crop effect in X works when in ‘trim’ mode.

    I’ve made the parameters default to linear curves between keyframes. You can use the Video Animation curve editor to change the curve interpolation style between keyframes.

    There are also some feathering controls.

    Oops, spoke too soon – only the first parameter has keyframe curve control.

    At least there’s more flexibility with the feathering!

    Alex this is amazing, you’re a genius!! a thousand thank-you’s.. you have just save my life/project…

    I just loaded fcp7 on a partitioned bootable drive so i could do the work on the clips i needed(with alex-crop1.1), but the workflow is so cumbersome, time consuming and frustrating that my film (which i have been working on for 4 years now, and needs to be completed by Nov) was going to be seriously compromised. But you have just changed that, i am so grateful…

    I hope you are aware of how valuable your contributions are to people like me.

    Next you’re going to tell me you are working a key-framed color correction filter…!!

    I’ve added a couple more effects to my blog post at https://alex4d.wordpress.com/2011/09/30/trim-fcpx-effect/

    Alex4D Trim L-R – which trims the left or right edge of a clip
    Alex4D Trim T-B – which trims the top or bottom edge of a clip

    As animation curves are editable for the first rigged parameter for each effect you apply to a clip, you can use these effects to have more precise control over your cropping.

    Alex

    [oliver michaels] “key-framed color correction filter”

    You might like to take a look at my version of this which I posted today:

    https://forums.creativecow.net/readpost/344/4670

    There are more refinements to come – if there is anything else you would like to see implemented do let me know.

    I’m sure Alex 4D will come up with something amazing, but until then this might work for you …

    This is great Simon!! What a great help this is..

    Thank you so much for the time and effort you put into these plugins. With alex’s crop and your keyed color correcting my work flow might actually start to flow! hopefully now i can get on with thinking about the film instead of being frustrated with software.

    Thanks, Oliver – glad it could be of use to you. Do check out the shadow/highlight diffuse options which I forgot to mention in my previous post – they can really add a lot to the look.

    Good luck with the film!
