After Effects renders with a complete different sound

[saimettl]

Hi, I make educational videos. I have slides and sounds from instructors and I turn them into an animation in After Effects.

So, I have audio files for each week like this:

sound1.mp3

sound2.mp3

sound3.mp3

.

.

.

I have many files named like this but they're all different. I have sound1.mp3 for all weeks for example.

Here comes my problem: I use right sound for each composition, I collect files, I use a folder for them, I rename them differently. I check them in my composition, they seem right when I play them. BUT when I render the composition, some audios are from another weeks. I play week 4 video and I hear week 5. I've cleared cash and I am still having this problem and it's a huge problem since I make videos for a university, I need to fix this ASAP.

Could you help me?

For information, the sounds AE mistakes have different length and names.

Hi Saimettl,

does this behavior occur, when you restart your machine?

There is no way the preview-render can be different than the final render. Make sure, that you put the correct audio into the correct comps and that you rendered the correct comp. Please note, that in AE you can switch between actual file name and internal name. So maybe you just mistook some audio files?

Also, check the audio files by themselves. If your naming policy is actual soundX.mp3, you might renamed some audio files wrong.

If everything is fine, but the error still occurs, you can export your AE comp as file without audio and put both together in Premiere.

Cheers,

Martin

It might just be me being old school, but After Effects used to hate mp3 files, and I never use them, even now, as a point of order, because they used to cause so many problems.  It's still a good idea to avoid compression whenever you can.

Preferably, source your audio files in uncompressed formats (aiff or wav).  Otherwise, convert your mp3 files to an uncompressed format before importing to After Effects.

Have you tried a full purge of memory and cache?

Then I would make sure all your file are in the right location, for example using the correct media folder not from downloads or something unknown.

Then I would make sure your files are correctly named as it could be human error. I would be more specific in labels

Hope that helps

I had this problem before, I don't know how it was solved.

I check every sound. Before numbering, after numbering, during my work and after rendering. You can be sure that they're not mistaken as I listen to every slide and work on them.

They don't all happen to end up bad. Just some of them. Today's work was urgent so I used my co-worker's computer to render the files and they came out just fine.

I did a full purge of memory and cache. Nothing worked.

Until I restart my mac. So, if this happens to anyone, just try restarting your computer first. It's really weird though, this shouldn't happen at all. Thanks for all replies.
