I'm trying to bring commerically produced mp4 videos into the video editor. Based on the mediainfo analysis, I think the FPS is around 60. But once in the editor, the properties of the incoming file appear as 15 FPS. The speed and sound are all messed up on playback and further editing.
Is there something I can do inside Premiere Elements?
Thank you

There are a few odd specs in the file. It's an old-style standard definition file that fits the old 4:3 rather than 16:9 aspect ratio. Was this ripped from an old video or DVD? Where did this file originate and did you or someone else convert it to an MP4?
That said, it would be fairly easy to convert the video into an editable file with a program like the excellent, free Handbrake.
You can find the basics of properly converting video in my free tutorial.
Just create the standard definition 720x480 file from it, as I show you in the first half of the tutorial, rather than the high-def.

Thank you so much for your reply. The original old analog videos were digitized by Southtree in Chattanooga. My source files (all home movies) were super 8 mm movies, VHS , video 8 / Hi-8, and mini DV. Then I went digital.
I have followed your Handbrake instructions, and it works. Another question: almost all my mini DV tapes were recorded in widescreen (16:9), but they were digitized in 4:3 display aspect ratio. Can I use Handbrake to expand them back out to widescreen? All my other tapes that were originally recorded in 4:3 were digitized in 4:3, so I think they are OK.
Also, I got two output formats: mp4 and DVD's. Is there an advantage to bringing DVD/VOB images (instead of the mp4 files created by Handbrake) into Premiere Elements? Quality? File size? Other?
Once I get the input digital file specs right, my plan using Premiere Elements is to create date/content segments (5 - 10 from each one or two hour source digitized video files) that can be used inside Premiere Elements and the Organizer for future tagging, editing, and projects.
I just got your Premiere and Photoshop books from Amazon, and am ready to dig in.
Thank you again.

That's a lot of questions for one post, FH. But here are the brief answers. But of course there's lots more to the story in each case, and they may be too complicated to tackle quickly on a forum post.
1) Handbrake isn't the best tool for turning 4:3 into 16:9. You're better off starting a 16:9 project in Premiere Elements and enlarging your 4:3 videos until they fill the frame.
2) It's hard to answer your question re DVDs vs. VOBs. A lot depends on a lot. If you have a VOB, use it as your source. If you have an MP4, use it as your source.
Thanks for supporting my books! Hope they help you out.
