I have Adobe After Effects CS5.5 on Windows 7 SP1. This problem has been reported by dozens of our customers, and happening on many, many videos made by me and my two freelancers. Many of our videos give playback erros on professional presentation software like Media Shout and Pro Presenter. I'm also able to see oddities when playing the videos in QuickTime player and Windows Media Player.
Often times I've been able to fix the problem by trimming the rendered extra black off the end of the video, but sometimes this is not possible because of trailing music. I am sometimes (but not always) able to fix the problem by changing the h.264 profile settings. I've had best success by setting HD (1280x720) videos to Profile: Baseline and Level: 3.2 (attached are setting screenshots).
I have tried 50+ setting varieties on 3 different computers, and I'm starting to think that there is a render bug in Adobe's H.264 encoder. The bug happens regardless if I use either After Effects CS5.5 or Media Encoder CS5.5 to render. Has anyone else had similar problems? Any ideas as to what to try?
I've not had any problems in my own H.264 exports using CS5.
But I will say that QuickTime and Windows Media Player are about the two worst players out there.
VLC, KM Player, UMPlayer, GOM Player are all good media players that seem to do a LOT better.
No fixes yet. I don't have CS6 so I can't speak to that.
Also, I know that QuickTime and Windows Media Player aren't the greatest, but that is not my problem. My problem is that the videos aren't encoded right. My customers and the general public use these main players. I can't fix that.
I've found a few things that occationally fix the problem.
None of these tips work 100% of the time. I can't seem to find a pattern. It seems like the best solution is to render h.264 with a non-Adobe encoder.
I have exactly same problem. And furtheron:
When I do a transition from black or into black I get some green/red vertical lines at the right frameborder. Just for the period of the transition.
When I export directly out of premiere I don´t get this problem. Just with AME. That´s sad, cos I can´t render out many files over night.
Oh, forgot to mention. Do it with and without the QuickTine compatibility mode. The QT mode disables parts of the h.264 standard the QuickTime player doesn't support. I suspect that's what you've been dancing around with all your experimentation.
Similar problem here, but not just with H264. I find AE's render capability is seriously flawed. In almost every codec I get frame glitches on any player, including inside PP CS 5.5. I have come to the conclusion that systems design did not do their work. And the other thing that annoys the cr*p out of me is when the cosy lot tell you to upgrade. This is no solution. I have CS 5.5, and expect it to do what it was designed for and which I paid for.
I bought a program by Corel called Motion Studio 3D, and first out, I was amazed at what it could do, for the price of peanuts, in comparison to AE. The next thing that totally surprised me is how fast the program was. It runs smoothly and renders considerably faster than AE. Yes, for more advanced stuff, you have to use AE. But the reasoning is that much of the advanced capability in AE you may only need after you're dead. All the stuff you need now, you can get with Motion Studio 3D, in a New York minute, with perfectly rendered and playable end result.
So as far as AE goes, my frustration with it, and generally all the other Adobe programs, has caused me to basically give up on it, because instead of them recognising and admitting to a problem, their answer is generally, spend more money and buy the upgrade. That is unethical. Fix what you proffered as working, and what you got paid for.
