Crop Video Stabilizer HELP!!!

MicahCDavis 22 May 2016 14:36
I want a video stabilizer that only crops (zooms) to make the image stable – 10%, 20%, whatever the clip requires. I don’t want algorithms that try to save the edges of original image size. So, if I shoot bumpy in 1080, I could output in 720, or if I shoot in 4K I output in 2K. Any ideas? We had this kind of stabilizer 15 years. It was simple and it worked very well. I want it again for high-resolution video.

Maybe I'm not understanding what you want but Warp Stabilizer in After Effects does all of what you ask.
Pull in your 1080 footage into a 720 composition and stabilize it.
You can turn off having stabilizer automatically crop.

You mentioned 4k and output 2k.
Just know that Pond5 doesn't accept 2k size. So you would have to output your 4k to 1080

Micah, yeah, use Warp Stabilizer -- it's my main reason for putting up with Adobe (although cloning out unwanted stuff is cool too)

kk5hy - you say they don't accept "2K" /// I remember seeing post where dude talks about 2.5K rejections, (and, I would assume, also, 2.7K) but what about 2048x1080 derived from DCI 4K?

I will give it a try... Thanks!

Also, not sure why you feel you "need" to downsize so much necessarily. (referring to 1080-720) If, after stabilization, the auto-scale is, say, under 105%, you will be fine resolution-wise (I usually limit to 103%, and if it's worse than that, I often find the stabilization results are icky anyway, and chuck the clip)

Mizamook,

Thank you. I just wanted to have plenty of room for cropping but I will try the 103% trick. My thought was that I could get a stabilizer that was cheap and did not "warp" the scene. I don't know if you have seen the old fashioned stabilizers that basically just crop the image and keep the objects in the scene still. Modern stabilizers seem to try to add on to the outside of the frame (in order to obtain the correct resolution) which can make the shot really jellow like. Warp seems like one of the best programs. For sure the best stabilizer program is Reelstabilizer. If you haven't seen it yet, look it up. It is just so expensive. I am pretty good with a Glidecam so I think that Warp will do the job.

At least the first month of After Effects is free. I find the trick is to be patient with it and mess with the settings so you know the difference in action between Warp, Perspective, Position/scale/rotation etc, as well as whether detailed analysis (under advanced twirl down) is worth it or better, and tweaking the amount of smoothness and crop less>>smooth more values, etc ... sometimes the "Preserve Scale" checkbox helps a lot, others it makes jello. Depends on shot. Sideways tracking shots seem really hard for it.

NEVER had luck with the synthesize edges ... it just looks snake farm nasty - in which case, I crop more and render to HD (usually shooting 4K)

You mean ReelSteady? I was Reel impressed by the videos, but I could not get it to work on clips I had problems with Warp Stabilizer, and yeah, expensive. I was hoping it would give an alternative to fix some more challenging clips, but besides the cost I think the other problem was, at least when I tried it, that it didn't use hardware acceleration and was slow...besides not working any better than Warp.

Very helpful information... Thanks!
