Play doesn't work in Timeline- Premiere Elements 15

[Guest]

I just installed Premiere Elements 15 and the play button in the timeline doesn't work.  It plays the video for about 1-5 milliseconds and stops.  I can hear choppy audio when it plays.  I can drag the cursor across the timeline and the frames do show and the audio also plays (v choppy due to manual movement).  The media is mp4.

The same thing happens if I just have pictures in the timeline (without sound).

I'm on Windows 7 with a Intel i7 2.7 GHz, 32 GB Ram, 64 bit. 

Video card NVIDIA Quadro M3000M, and NVIDIA High Def audio card; they are both updated drivers. Symantec is the antivirus running.

I also have AVS video editor program loaded on this PC and it works fine when i run the same videos on it.  I don't have AVS and Premiere running at the same time.

thanks,

Adrian.

I also tried Rendering, but that doesn't help.

.MP4 is a "container".  It can have a wide variety of codecs and variations. 

What is the source of your clips?  Can you use MediaInfo and post the description in the Tree view?

My first guess is that whatever your source, it is recording in a variable frame rate.

One video was taken on a Priv Blackberry, but i also tried from a Sony camcorder, and like i said it doesn't play even simple pictures on the timeline.

It plays fine with VLC once I export from Premier (HD 720).  It just doesn't play in the timeline so i can check while i'm editing.

From Mediainfo:

(1) the Blackberry video is:

General: Codec ID is mp42, overall bit rate: Variable, Overal bit rate 9 213 kb/s,

Video: Format AVC, Frame rate: Constant, Frame rate 24.000FPS,

(2) the Sony Camcorder is:

General: MP4, CodecID M4V, Overall bit rate 3 463kb/s

Video: Format: AVC, Frame rate: Constant 30 FPS,

Hi,

If none of the media play after importing to Premiere Elements editor please try the following:

• Click on edit> preferences and get to Audio hardware (you may get an error while getting to audio hardware, if you do click on Okay and get to audio hardware window.)
• Here, set default input to 'No input' and check if the correct speakers are listed under Default Output.
• Click Okay to close preferences tab and check if the video plays.

Such issues may occur due to incorrect hardware settings in preferences.

Hope it helps

Thanks and regards

Did what you said with no errors but it didn't help.

Also changed Audio Class from MME to ASIO but didn't help either.

C:\Users\*user name*\AppData\Roaming\Adobe\Premiere Elements

Now it plays ok.

But now when I add markers (4 key frame points (?) ) to the audio line and lower the volume of a section, and when I play that section , the program crashes immediately,  without warning.  I did it a few times and it's very repeatable.

Hi,

Please check if the clip(s) you are using in the project are in .mts format. If they are, try to convert them to a different format say .mp4 or .mov and check if you still experience crash.

To try this you may download/ install Handbrake which is a video converter program.

Thanks and regards

My play button stopped working. It had been fine for weeks, then an hour ago, it wouldn't work on any projects that previously worked. I tried a few different things to fix it. Eventually I got it working again. Here are the things I did. I don't know which one fixed the problem. 1) I opened up an earlier version of Premiere Elements and played something there. Then when I reopened 2018, the first project I opened worked again. 2) I also shortened my project file name, which was getting ludicrously long. 3) I pressed the rendering button. Collectively, those things fixed the problem. Hope that helps!
