I'd love to hear from Adobe Staff on this one. Hopefully they can focus on fixes over features for the next update, especially for one it's most touted effects.
Warp Stabilizer works great at stabilizing clips in Premiere Pro CC...but I'm beginning to learn that it's quite buggy. The two bugs below simply cripple the user experience when you use the effect a lot like we do. Here's a link to a sample project with just 2 clips (around 1 minute in length each) on two separate timelines with each clip stabilized using the Warp Stabilizer effect. It's only a sample/test project meant to show the issue which can be MUCH larger in a longer/bigger project. Relink to any longer media and you'll quickly see what happens when you have multiple warp stabilizers applied to a Premiere Pro CC project and how problematic it can be.
See for yourself.
Two VERY Annoying BUGS and One Unfortunate Feature:
BUG #1: (It affects 7.0.1 and the new 7.1 Release/Update)
1) With GPU Acceleration Enabled and both sequences open, once the timeline render bar has turned yellow, hit save.
2) Now toggle to the 2nd sequence and you'll notice a delay/freeze as the render bar switches back to red and then yellow again.
3) Now toggle back to the other sequence and you have the same thing occur. Then, you can toggle back and forth with no delay...until...the project saves (or auto-saves) again...and then the delay/freeze will happen all over again.
4) Side Note: Even when you right-click on the sequence in the Project window, there's a delay. Right-click on a sequence with no Warp Stabilizers and the drop down list pops up immediately.
What's the Big Deal?: When you have tons more warp stabilizer effects applied to multiple sequences, not only does it take a while to save, but when it does, you are forced to wait while Premiere Pro freezes momentarily. This affects AUTO-SAVE too!!! The more warp stabilizers, the longer the wait. Our sequences have delayed up to 30-40 seconds depending on how much we've used warp stabilizer in each sequence. Imagine if you have Auto-Save set to every 30 minutes or less, well that means that every 30 minutes or less you'll be forced to stop while premiere freezes up for 30-40 seconds or so (depending on how much this effect is used). Other effects do NOT have this issue.
BUG #2: (It affects only the new October Release/Update of Premiere 7.1...this issue is NEW and does NOT occur in 7.0.1!!!)
1) Take the above project into Premiere Pro CC 7.1 (again, this does NOT occur in the previous 7.0.1 release) and hit FILE>EXPORT>Media.
2) You'll notice a delay while the EXPORT SETTINGS popup opens.
3) Toggle to different "FORMATS" in the export settings window and there's more delays every time the format is switched.
What's the Big Deal?: Again, this is a small sample project. When you have a much bigger project with lots more Warp Stabilizers applied to many more clips this "delay" can extend up to several minutes!!! Yes, on a recent project over an hour with MANY warp stabilizers applied to lots of clips, it took 7 minutes for the Export Settings window to pop up after hitting EXPORT>Media. And there was about a one minute delay now when switching formats. This occurs whether GPU Accleration is enabled or not. It ONLY occurs on Premiere Pro CC 7.1
UNFORTUNATE FEATURE #1:
We obviously use Warp Stabilizer A LOT. It's a great effect. The above bugs cripple the user experience. This last issue isn't a bug, but rather a default setting on Premiere Pro's warp stabilizer that should be changed. Within the settings of Warp Stabilizer there's a section called "Method". The default setting is "Subspace Warp". That sounds pretty cool. But in practice, and we have had lots of practice (eg. THOUSANDS of clips stabilized in just the last few months alone (no exaggeration)), we've found that switching the default method to "Position, Scale, Rotation" is a MUCH more effective way to stabilize a clip. Most of the time it cuts down on that "wobble" that you might see in complex moving clips...but more importantly, 9 out of 10 times it crops the video either the same or less than when you use the default method. By "crops less" I mean that the "Auto-Scale %" is less. Of those 9 times, I'd guess 7 or 8 of them would crop in on the video less while the other 1 or 2 times there would be no change to the Auto-Scale %. Less scaling = better.
What's the Big Deal?: Well, as cool as Subspace Warp sounds, our numbers don't lie. Again, we use this effect on HUNDREDS of clips every week. When you have to go into hundreds and hundreds of clips every week and keep switching the setting so the effect will work better, it gets old real fast. We end up wasting so much time doing this but it's worth it because the results are undeniable. Why not create a CUSTOM PRESET???! Well, that'd be nice if it worked...but it doesn't. The problem with a custom preset like that is that when you drop it on a clip, it doesn't activate/analyze the clip automatically so you have to manually go into the settings and hit analyze which negates any time saved. It's be great if the default "method" was simply changed to Position, Scale, and Rotation. Or at the very least, it'd be great if one could create a custom preset that would automatically activate/analyze the clip it's dropped on (just like the original effect does).
(BONUS FEATURE: It'd also be nice to have the ability to set a "max scaling %" too so you never crop in more than a preselected amount...but first things first...fixes over features.)
