My audio play really FAST when i scrub/render FFMPEG

Hi, ya’ll.

i did the usual, added the audio in the sequence editor.
But when i scrub my audio play really fast, even when i scrub by just one frame, it play audio of more that a second, really fast. like the chipmunks.

I started a new scene and just added audio and it still does the same thing, i guess there must be some setting i am missing, it not the scenes, just blender settings.

A heads up would be much appreciated.

check you have it on the correct rate

44.1 kHz/48.0 kHz

and hit recalc

any help?

#3

No, the recalc thing definitely changes what i hear, but its still playing really really fast.
just scrubbing by a frame, and it goes wild.

this might help if i was doing a chipmunks thing but, fuck, not now blender, not now.

Any more suggestions?

#4

what format is your audio in
format and sample rate

you may have to convert before you import

#5

The audio is fine, its a .wav file
running at 44.1 kHz
16 bit
Stereo
file size: 45MB

it plays fine when i load it as a sample in the Sound panel. plays nice.
Mem cache: 512MB

more ideas please!

#6

what is your frame rate set at?

#7

my frames rate is at 25 fps.

thanks for your effort but fuck it. i am done.

I think i started having this problem after installing 2.49 a week ago, all my scenes that have audio now are playing like this. There must be some new funny button in 2.49 that wasn’t in 2.48?

I don’t know anymore.

#8

make sure the frame base (next to the FPS) is set to 1

but does 2.48 still work?

I haven’t tried audio in 2.49 yet
but I haven’t heard any other people with this problem

what are your specs, OS etc

maybe it’s OS, or hardware specific

#9

I’ll reinstall 2.48 like at 13:00(GMT+2) and test it out and then i’ll get back to the forum.

but either than that, I’ve got to move on. maybe i might find something interesting, but i would count on it.

thanks man.

This will probably get Waylow excited::eyebrowlift2:

I’ve reinstalled 2.48a - this was the version i created my scenes that have audio with.
Now, the scenes play fine with this version.

i tried with 2.49 and the audio plays fast when i scrub, surely there must be something “new”/weird in 2.49 in regard to audio.

I am tempted to pop the hood but i am under the clock at the moment, i have to finish this project i am busy with, maybe this weekend i’ll fish around to see exactly whats “new”/weird in 2.49.

Shit, i love solving problems.:yes:

Sorry to post in a month old thread, but I was wondering if there is a solution to this problem in 2.49a?

In the sequence editor and renders, video .avi files with mono uncompressed 8-bit PCM audio at 11024 Hz sample rate sound like a chipmunk on Red Bull caught in a solar flare during a ham radio convention. They played back fine in earlier Blender versions, but this is not a viable solution for me -I need to use 2.49a. Is this a problem with the sampling rate? waylong’s suggestion didn’t help me.
