editing frames of of a clip

[JerryB]

hi,
I am not sure if explaining myself well enough in asking the question but here goes...

2 questions really
1. Is there a program or plug-in that can edit film at the frame level without doing each individual frame... for example desginating a artifact to be removed from one frame and the program will remove it from the othe sequential frames...! or selecting a element, to do a change like color a box , in a frame and have the program automatically change that color in all the other frames .... I have heard about new technology in R&D but i haven't found anything yet....

2. The other question although related, I have been reading up on liquid resizing, also called content aware, or seam carving. basically it able to resize without croping and distorting ...
this new technology has already been implented in photoshop cs4 , also plugin for gimp.and i have seen a couple of online free editing sites incorportating it... real nice...

however, for video editing I haven't seen or found anything yet...!!! has any one heard or seen some program or plug-in for video editing..???

the is video explain what it can do and what i am looking for....

this link for those who are interest in seam carving for images tell what it about and what it can do.... http://cybernetnews.com/cybernotes-photo-seam-carving-using-liquid-resize/

1) no, because the detection algorithm would make errors when the object is moved into different frames. Even a "still object" appears to move when the camera moves. And what happens when 1/2 the object is on the frame (with 1/2 off) or shot at a different angle? Will it still be "detected"? You basically have to do these things manually if you want any accuracy

You can , however, change a color to something else. e.g. all dark yellows become green for example. You could use after effects , it has plugins that do exactly that.

2) You can disassemble your video to lossless pngs, do your content aware scaling in your image application on a frame basis, then reassemble your video from the pngs.

1) Yes its possible, you'll have to learn motion tracking though, and the quality of the results will be 100% dependant on the quality of yoru tracks.

2) I'm not aware of anything out at the moment, and from the link you gave i'm not suprised, some of the artifacts and distortion even on what was meant to be representing their 'good' work was horrific.

You can do some of the want you want with high-end tracker/rig removal tools like Mokey, ot even using keying and cloning in After Effects. However even in studio work, rarely is it all automated. Automation makes it easier, but ultimately most frames get a hand touch up to be sure. Photoshop Cs3/CS4 Extended can import and work on video, then export for editing back into the master.

Content aware scaling works (if you can call it that) in only a small set of circumstances. It cannot be applied successfully in many situations (in fact, in most situations it doesn't work at all), and even in the types of situations where it should work, it rarely works without leaving distortions and artifacts. You are better off, in many cases, masking, rotoscoping, and replacing the background with something that better fits.

hi
poisondeathray

thank you for the reply.... i was hoping.. smiling... that maybe someone has heard something.... ever since i read up on seam carving in video.. i was thinking they would use of thier capabilities in addressing more deeper editing that what is currently avail...

As far as importing a clip and then break it down to png images.... for 1 or 2 hour movie... for my limited skils.. wouldn't be practical and not sure if my current pc powerful enough really for that....

but thank you for your thoughts...

hi fetch,.
motion tracking...mmm... i guess i will... i see and hear a lot of R&D and i guess.... some the stuff just not there yet and i guess i will have to work on motion tracking....

thank you though for your reply......

hi gunslinger...

I took a look at after effect..... thinking about that.. but it will be awhile before i can afford that... i'll take a look a mokey... thank you for that...

yes seam carving is not ready for proffessional work. but for my uses it would be fine.... i expect a lot more improvement on it in the future.. the technology i believe is only 2 years old...
I i took a look at how PS cs4 handle it.. adobe needs a lot of work i think they rushed that one...

i don't but i would assume that there getting a form of it ready for there next version of premiure... but we'll see... thank you verymuch for your thoughts andhelp
