I recommend you try this
Go to Edit> Preferences> Media and remove the checkbox before the item: enable Intel h.264 decoding (requires restart), o (12.1.2) Enable hardware accelerated decoding.
If you still have problems with some files, close Premiere and proceed to delete the cache folders; note the link for the instructions:
Start Premiere and re-import the file.
Ok, so it still isn't working, On the upside since I created proxies they work and I'm able to edit the footage but not export it to the quality it should be. Last night I started another project but the files are 1080, I didn't have any errors thrown when I was importing any files. So could this be an issue with high-resolution video? I'm not sure why that would make a difference but. idk
The solution to this message "A low-level exception occurred in: Importer MPEG (importer: 39)", is the one of my previous post, but, when it comes to MP4 or MOV.
The strange thing about this post is because it's M2TS, generally these are 1080, and this is a 4k file error or higher.
Another strange thing is that by default Premiere 12.1.2 has the Intel decoding for the MTS files disabled.
I'll have to keep investigating.
Yeah, idk. It is just weird I'm getting this error. I generally shoot in 4096 x 2160 17:9.
Also, you would think of it is importing just fine on one computer it would do the same on another computer.
Thank you for trying to help, I appreciate it!
Dude .. premiere was working fine for me .. now .its
driving me nuts ! why Adobe? .. Im tring to import H264 Mpegs
Are you using a laptop or Desktop? What are the specs? What resolutions are you shooting at as well? My issue is with 4k video. It really stinks that it's doing this.
Something you can do till whatever this issue is fixed and this sucks doing this but make a duplicate file and change the file to a .M2TS file and you should be able to work with it in premiere then.
