I don't see any real difference between any of the clips besides size. They all play fine for me.
I never use Windows Media Player. Mostly I use the KMPlayer.
thank you for the quick feedback!
So I believe that the exports are technically o.k. and I can savely use the h.264 premiere preset.
Maybe, someone has an idea why Windows Media Player 12 (On Windows 7 x64) has problems playing these h.264 .mp4 exports while it plays fine the original .mov files - which indeed are also coded with h.264.
The issue seems to be Windows 7 related.
To have the chance of writing a more appropriate Thread, I will open the issue as a new discussion.
I tested on Windows 7. There was no issue using KMPlayer. If WMP doesn't work, just don't use it. (Hell, I recommend that even when it does work. WMP is about the worst media player out there.)
Jim, thanks for testing.
My concerns are about a)distribution and general b)compatibility.
a) When videos are distributed most of the users will probably try to open the files with Windows Media Player. So it is not a good start to have fresh exported h.264 videos which won't run fine with the 'main' player on windows
b) I am wondering if the Problems with Windows Media Player may also be a sign of a general compatibility issue of the h.264 video itself
At least in case b) Adobe would have to look into this.
Here is another test video:
I ran some more tests. WMP 12 on Windows 7 64 bit did have trouble playing both your MP4 export as well as my own. I just never noticed before because, like I said, I don't ever use WMP.
However, the F4V exports using the H.264 codec seem to play back just fine on all players.
thank you very much for the tests.
I would like to forward this issue to Adobe so that they can investigate it along with Microsoft.
I have opened a new - more appropriate - discussion about this problem:
Windows 7 x64 - Encode h.264 results in jerky video in WMP 12
forward this issue to Adobe so that they can investigate it along with Microsoft.
Good luck with that.
