feature request: time modification with pitch change about ffmpeg-audio-encoder HOT 8 CLOSED

I can look into the feature request after the weekend is over for you.

Any chance you could drop accurate documentation on how this is done via CLI properly?

Also the save current settings is different per codec. Could you please post a screen shot of the codec window with the settings you are attempting to save. Thanks!

I should have this feature done by the end of the day today for all codecs

I read about asetrate here: https://forum.videohelp.com/threads/396848-PAL-DVD-change-frame-rate-25-23-976#post2580562
I tried it in the CLI of your program but for some reason, the pitch didn't change. Perhaps give it a try with your files.
In any case, it would nice to have it in the GUI, since lots of old media has the wrong pitch.

FYI, ProWo is the author of clever FFmpeg GUI, which does pitch correction but doesn't have qaac support. That's why I tried your program.

And never mind the save current settings comment I made. Tried it again and it works, sorry--false alarm.

I had about 15 minutes to look into this after work tonight. I'm going to look into it more tomorrow.

However, I was successful in using a custom command line parameter.

-af asetrate=44100*3/4,atempo=4/3

This command enabled me to do what you wanted with QAAC. I'll need to read into this more and mess with it more tomorrow as I need to sleep tonight.

Are you sure this is what you want?

from ffmpeg-audio-encoder.

Yes, thanks! I guess I wasn't using asetrate correctly. Using -af asetrate=48000*24/25 with atempo=25/24 works.

(What I tried previously was asetrate=48000*25/24)

Would be great in the future to have this option built in. Alternatively, could you make it so that the 'save current settings' also saves the ffmpeg custom command?

from ffmpeg-audio-encoder.

I think, without changing too much code, it would be best to just save the custom command line vs adding a GUI option in for that for all codecs.

This will be a good way to do what you need without digging in too deeply. Let me see what I can do now, as I have a little free time.

from ffmpeg-audio-encoder.

Yeah, no problem. The only issue is that the 'save current settings' does not save the ffmpeg command, so it has to be stored externally. Would be nice to be able to save the ffmpeg command as well. Thanks

Program now saves custom command line to the profile. Download v4.04

Feel free to post back here and let me know the results!

EDIT: Also it's important when using the command asetrate that you input the files sample rate correctly! If it's 44100/48000 etc... you need to input that correctly with the asetrate command
