Audio Issues with MPEG4 Video in Premiere Elements
Premiere Elements seems to be a dream ticket for a specific department’s needs at our company because of its ability to import, edit and export WMVs, MPEG4s and FLVs.
However, after importing MPEG4 video files into a project the audio becomes full of glitches. Repeatable glitches. Pops and distorts which occur in the same places again and again. These glitches then appear when the clips are exported.
I’ve tried the same on three different machines – one AMD, two Intel, 2 with on-board audio, one with a separate sound card, and they all do the same thing.
I thought it might be a sample rate issue – because for some reason the seuqnces in Premiere Elements are set to 48Khz 32-bit when the audio is 48Khz 16-bit. Then again I thought 16-bit was kind of the standard.
Or is it something to do with the KIND of MPEG4 I’m importing? When exporting MPEG 4s from FCP you can do MPEG4-Basic, MPEG4-Improved… these files are from the public who are rather hard to get to conform to standards…
And help massively appreciated.

I have worked with WMV files on the timeline with no problem but I have not worked with MP4s. One solution, if possible, is for the FCP output to be exported as MOV instead of MP4. The quality would be higher because there would be much less compression. FCP could also export to DV tape and that would solve the problem. Is this an option?

Maybe someone else has experience with MP4s on the timeline. -
Hi Rich
Thanks for the reply.
My FCP example was just suggesting that MPEG4s could be done right and wrong. The problem is that the MPEG4s that this department is dealing with are *User Generated* – they’re uploads for a documentary film website. We give very detailed instructions for asset upload but you’d be amazed (or maybe not) at how completely wrong many of the files are in terms of specs – sample rates, frame sizes, frame rates, codecs etc…
While going through FCP or dumping to tape wouod certainly “Normalise” the footage – it would generate a massive amount of extra work for the department dealing with the films and probably degrade the often fairly degraded films already with yet more encoding stages.
Premiere Elements is a shockingly powerful program for its price. If I can get it to work (accepting a lack of batch export),for what we want it to do, it will thrash FCP Studio and Sorenson Squeeze in one go. That’s

Hello,
I have exactly the same problem. Periodic noise added to .mp4 when using Première.
Have you found a solution to this audio problem?
Thanks,
Jm
