Welcome to the forum.
Can you give us more information, please.
You state that the files were created from 8mm originals. What are the full specs. of those files - more info, the better?
At New Project, you have several choices for the Project Preset. What did you choose? With that original source material, prior to any telecining, digitizing, etc., it would seem that for DVD-Video output, the choice should be NTSC, or PAL (depending on where you live), DV Standard 4:3 (unless that material was shot in 16:9 Widescreen, but I doubt it), w/ 48KHz 16-bit Audio.
Going along with what Hunt asked, here is how to find out and report just what it is you are editing

What CODEC is INSIDE that file? http://forums.adobe.com/thread/440037
Report back with the codec details of your file, use the programs below... a screen
The original files were ripped from a DVD (we paid a company to convert the 8mm movies to DVD) in mp4 format. On import, I selected NTSC 4:3. There is no audio on the files imported, but there is an audio track in Premier, I just didn't bother deleting it since it is blank anyway. I will also attach a screenshot of what I am working with. You should be able to see some of the lines, especially on his arm. These come and go throughout any production I make and are not in the original. The same problems happened when I tried to edit some mp4 files from my Sony and GoPro cameras.
Please go back and read what I posted again... MP4 is a wrapper, which may contain many different codecs
Exact information on the codec inside that wrapper MAY help someone answer your question
Also... in general... MP4 is HIGHLY compressed, and does not edit well
"Codec Status Undetermined" is not a good sign.
BTW, how did you rip video from a DVD as an MP4? If you used Premiere Elements Add Media/From DVD, it should have come in as an MPEG2.
Did you use some software that converted it to an uneditable format?
>files were ripped from a DVD (we paid a company to convert the 8mm movies to DVD) in mp4 format
OK... tell me if I am wrong
1 - you pay a company to convert 8mm tapes to a playable "movie" DVD... not a data DVD... is that correct?
2 - if my understanding of #1 is correct, that gives you a DVD with a series of VOB files... which are compressed so a 13Gig per hour video will fit on a 4gig disc
3 - you then FURTHER compressed those VOB files by ripping and saving to MP4... again, is that correct?
If you do, in fact, have VOB files on a "movie" DVD, read below

Edit Vob http://premierepro.wikia.com/wiki/FAQ:How_do_I_import_VOB_files_/_edit_a_DVD%3F
While far from perfect, editing your VOB files is likely going to give you better results than trying to edit a TWICE compressed file
This problem happens with all videos that I have tried - they just all happen to be in MP4 format. I ripped this particular DVD with Handbrake, but the same thing happens with the files from my GoPro and Sony digital camera.
Well, you're using Handbrake. And that's exactly the issue.
Handbrake is great for creating MP4s if, for instance, you want to put your movie on your iPod.
But, if you've got a DVD and you want to edit the files, you do what the instructions say in the box (and in my books): Put the DVD in your computer's disk drive, then use Premiere Elements' Add Media/From PC DVD or DVD Camcorder to open the Video Importer. Use the Video Importer to decide which files you want ripped to your computer.
Premiere Elements will rip the files to your computer as MPEGs and simultaneously add them to your Premiere Elements project for editing.
>same thing happens with the files from my GoPro
Well, as I said, MP4 is highly compressed and does not edit well
More information on GoPro
-says Cineform WITH GoPro, to convert to other formats
> and Sony digital camera
Posting the exact model of Sony might help, along with the Gspot data for the files from that camera... which MAY not be the same as your other MP4 files
Jerky or slow playback http://forums.adobe.com/thread/1071217 may also help

Steve's Basic Training Tutorials... steps are the same for several versions
I will give this a shot. I played with the program and reimported my mp4's from the other sources with no FX and then added them manually and I now have acceptable quality. I will do the same with the DVDs and see if those improve as well.
Thanks for your help.
