FFMPEG

Post by blakovic » Sat Feb 03, 2018 3:19 pm

is there a way to use a newer FFMPEG? maybe 64bit?
I do import and export large audio files from my cam, around 5-6h lenght through FFMPEG and this is SLOOOOW as hell, the only working is v2.2.2 (32bit I guess?)
is there a chance to upgrade ffmpeg to newer or 64bit, maybe it would help me to speed up things

Unfortunately, updates to FFmpeg frequently break compatibility with earlier versions, which then requires substantial work from the Audacity developers to fix, and means that everyone updating Audacity will also have to reinstall FFmpeg. Consequently, the Audacity developers are not keen on updating Audacity's FFmpeg very often.

One way round this problem is to use Audacity's command line export option. This should work for any version of FFmpeg: http://manual.audacityteam.org/man/expo ... ogram.html

Audacity isn't a video editor, it's an audio editor. To edit a video you will need to use a video editor.

If you wish to edit the audio only part of the video and the place that audio back into the video:
1) In your video editor application, "export" the audio track as a WAV file.
2) Import the WAV file into Audacity, edit it as required, and export as a WAV file with a new and unique file name.
3) Import the edited file into your video editor application, and save (export) the modified video.

Windows Movie Maker is the obvious one.
For Windows 7, see: https://answers.microsoft.com/en-us/win ... 5f38515a47

There are also several other free video editors.
filmora is NOT free, despite their aggressive marketing to imply that it is.

Sorry but we are not able to offer support for other people's software. I don't use Windows Movie Maker, and rarely use Windows at all. Try searching on Google - that's what I'd do.

audacity is great in editing but with big audio files around +3h from my cam it works pretty slow, when I scroll audio file (from left to right) audacity freeze (for about 5-20sec) HDD loads are about 5-8mb/s

working on SSD is much more smooth but you know... I'd kill my SSD within a year because audacity create 30-40gb file from my 500mb audio file which is craaaazy

oh one more thing I wish there was a feature to add/remove buttons and add feature to configure mouse events like wheel those pre-configured are useless for me

I would suggest working on current active projects on the SSD - and then archive finished or temporarily un-worked on projects to a large hard drive (my HP PC has onboard am SSD C: drive with 256GB and a D: HD with 1TB - thus making it a good tool for Audacity working)
