Encoded video sounds different than what's on my timeline !?! (Dehummer FX not working?)

[Appaluci]

I have a video/audio clip with a hum in it. I applied the Dehummer effect to my audio and the hum is gone when I playback from my timeline within Premiere. I export the clip as an H.264 .mp4 using Adobe Media Encoder. When I play the encoded clip, it has the hum.

I only just started using the latest CC upgrade, so wondering if there's something simple I'm just missing to get my audio effect to work right? It doesn't make sense to me why this would be happening.

Thanks.

did you add it as an obsolete effect or the newer version?

[Appaluci]

The fact that I don't understand your question makes me think I did miss something simple.

How can I find out?

[Appaluci]

If you're asking what version I have of CC, it's 12.1.2 (the latest I think?).

I used the dehummer fx that is in the audio effects list.

[Carlos Ziade]

inside the audio effects list there is an obsolete bin in which there is also a Dehummer,

which is the old version of this effect that might or might not work properly, and there

is the Dehummer which is in the audio effects outside the obsolete effects bin. So

check which one you are using and try to use the other one. This might not be the

solution, but let's test it please.

[Appaluci]

So, I pasted a picture of my effects bin, because I am not sure what you're describing. Unless I'm totally missing it, I don't seem to see any reference to an obsolete bins of effects. Should I be seeing this? In this picture, it is showing you the DeHummer fx that I used.

Remember - applying the fx worked in my timeline and in rendered clips, but somehow the encoded version sounds completely different; so strange.

Thanks

I'm wondering if you saw my response question. In my effects I see the "Obsolete Effects Bin" but I can't tell if anything is in there. When I click on it, nothing expands or contracts, but my list of effects is all below it, and indented in, looking as if it is in that bin. I'm a bit confused. Are these obsolete or not? Why do I have this bin if it's empty??

[Carlos Ziade]

did you accidentally check 'Bypass' to the Dehummer in the effects control panel?

if you are playing back and checking bypass to hear the difference, then click space bar,

this will check and uncheck it until you select the timeline again to stop the playback...

Please double check your 'Bypass' from the Effects Control Panel under 'Dehummer'

[Appaluci]

No, bypass is indeed not checked.
All I do is apply the audio fx to the clip - and in the case of the dehummer, it takes the hum out instantly when I play back on the timeline or render on the timeline. The I encode that same spot, and hum is in the encoded clip.

It's quite a mystery, isn't it.

[Carlos Ziade]

can you please share your system specs, operating system and the exact version of premiere you are using?

Thanks!

[Appaluci]

You bet. And thank you for your time and help with this!

OS = Windows 7 Ultimate 64 bit

System = AMD Phenom II X6 1090T processor  3.20 GHz

Fixed in  Premiere v14

[Peru Bob · Accepted solution]

Actually, it was fixed in 13.0.2.

[Hudownik]

1) First of all, go to your player settings (that you use on your PC/MAC) and turn off normalization/EQ/BOOSTS whatever can change the audio signal .

2) Turn off your Premiere and clean all temporary files from  "Media Cache" and "Media Cache Files" folders

PP might use temporary files wile rendering.

3) Some effects that working in real time can mes up the sound. Like DeHummer/DeNoiser/DeRewerb, Especially when it used IN nested compositions.

For example DeNoiser needs about 1 - 5 sec to apply affect properly. its you apply it on audio track and nested it. Every time nest nested  composition starts in Master composition effect will screw up audio for first 1 - 3 sec. 

(Interesting that its not an issue when you preview video in PP, but it is when you render it out) 

To fix it. A) apply DeHummer/DeNoiser/DeRewerb at audion trek in Master composition. 

or B) render audio that uses this kind of effects separably and import that audio in project.
