What version of Premiere Elements and on what computer operating system is it running? From your comments, I am assuming that you are working with Premiere Elements 12/12.1, 13/13.1, or 14.
Please explain "cannot render". Are you working in the Expert workspace?
Do the gray tabs of the Work Area Bar span the entire Timeline duration that you want to render to get the best possible preview?
Are you setting the project preset manually or letting the project set it automatically based on its analysis of the properties of the first file dragged to its Timeline?
When the video arrives at the Timeline Video 1/Audio 1, is there no colored line over it or an orange line over it?
Where are the Scratch Disks for Video Previews saved, and how much free hard drive space is at that location? See Edit Menu/Preferences/Scratch Disks and its Video Previews category.
What is this 720p file ---1280 x 720 @ what progressive frame rate -- file extension, video compression, audio compression....?
What is the project preset for this project according to Edit Menu/Project Settings/General?
Please consider. Then we can decide what next based on the details in your reply.
I'm currently using premiere elements 14. I was not in expert mode, though
it is the mode I needed to use, I was in the quick option. When I say it
doesn't render, what I mean is that the video was added, and it would not
play past the first cut or edit. After I made any modification the video
would cease. I wasn't using any of the presets at the time and I have 3
terabytes free in the hard drive. The video type was mpeg-ts at 30 frames
I am now only editing a minute of video and it still wont play at the top. I have the audio going but why wont the video go. like seriously. I paid 100$ for a program that wont work..
Thanks for the replies. Let us see what we can put together to get your Premiere Elements 14 project moving forward.
I know from personal experience that a MPEG2.ts file should be supported by Premiere Elements 14 Windows....imported, edited, Timeline rendered, and all the rest.
Before we go anywhere on this...do you have the latest version of QuickTime installed on your computer along with Premiere Elements 14 and are you running the programs as administrator (from user account with administrative privileges)? If yes, we continue...
1. Do you know what the properties of your MPEG2.ts file are in the way of frame size, frame rate? What are they?
2. Import the .ts into the project's Export workspace using Add Media/Files and Folders/Project Assets. When you drag the file from Project Assets to the Timeline, the project should automatically set the project settings based on its analysis of the properties of that file. So, what did it set...See Edit Menu/Project Settings/General. Assuming that what you see there represents your video correctly, then there should be no colored line over that video when it arrives on the Timeline.
3. Is there no colored line over the Timeline content? If we have the right project settings, there should be no colored line there. In your screenshot 3, you are showing Timeline unrendered video. Note the orange line above the Timeline content. That could mean
a. we have the wrong project settings
b. you have the correct project settings, but you have edited the content...all edits after a render take you back to the unrendered state. Render and unrendered are related to previewing.
In post 3, the gray tabs of the Work Area Bar span the entire Timeline content. So you are OK there. Are you saying that if you
a. Press the Enter key
b. Hit the Render button
c. Use Timeline Menu/Render Work Area
that you do not get Timeline rendering?
Please consider and then we will decide the next step(s).
