This seems like one of those bugs that's meant to be fixed in the next update. Adobe has said that, if all goes well, the update will be here in less than a week.
Still happening even after the update.
What happens if you split your video into smaller chunks?
Also, what is the format and codec of the footage?
19,000 frames is an awful lot! How long is this clip?
It's format is AVC and it's codec is avc1. The clip is shortened to 5 min. and 21 sec. Not sure how to split the video for stabilizing.
Split the clip with CMD+D on Mac or CTRL+D on Windows.
Is that one long shot? It's a pretty long thing to use the Warp Stabilizer on. I'd use it on 30-second chunks and see if that works better.
Although, your codec might be causing AE fits. Let's test that. Use the Adobe Media Encoder. Transcode your footage into QuickTime with the PNG codec. Try running the Warp Stabilizer on the resulting clip.
So splitting the video into roughly 30 second segments worked! I didn't have to change the codec. One minor problem that's just a bit off topic, using the warp stabilizer on each layer caused the composition to look choppy when played between layers, like when a DVD skips ahead a tad. It's understandable since the average movement of each clip is different. Anyway to sort of smoothen it out? I've tried a sort of dissolving transition by altering the opacity, but it's still noticeable.
You have a couple options. You could keyframe the position and scale of the layers to make it a lot less noticeable.
I seldom run into this kind of problem because the average shot in any of my projects is less than 4 seconds. Sure, I have longer interviews and occasionally I'll set up a very long moving shot for some kind of effect. I once followed a firefighter through a burned out building with a hand held 35 MM Arri 35 2C. The completed shot looked line one shot but in actuality it was 10 separate shots cut together to hide the cuts and this was 35 years ago, way before Warp Stabilizing. If your production design requires you to "stabilize" a very long shot then success starts with planning the shot and finding the right cut points to use as transitions. Even in warp stabilizer you can find parts of the shot where you can overlap, match, scale and fix the transition. Here's how I would handle a very long and poorly executed shot..
- Look for the any parts of the shot where the camera was really stable for a few frames and set markers
- Split the shot at the markers but then add about 30 frames of overlap to each shot
- Warp Stabilize each section of the video using the same settings (if the settings are animatable make sure they are the same for the overlapping sections)
- Render each of my stabilized clips and replace them in the original comp
- Set the blend mode of the top copy of the split clip to Difference
- Go to the out point of the bottom layer and set position scale and rotation keyframes on the top layer
- Move back to a point in the overlap where the screen was mostly black and adjust the top copy to get a mostly black frame
- Change the blend mode back to normal and trim the top clip so the frame that was black is now the first frame of the top clip
- If you have exposed the edges of the frame on the top copy and you need to fix it add a null and parent the top and bottom copy to the null
- Set position and scale keyframes as needed for the null to hide the edges.
There you go, a perfect cut between stabilized portions of your video. All it takes is a bit of planning.
