I've been using kdenlive for my little home movies and things like that for the past year or two, I really like the software and it works great now that I have a process. However the one thing that I'm missing is the ability to keep the audio when speeding up my video. A lot of times I speed up my video because the footage is too boring to watch at normal speed, often times I'll go to 400%. But as we know the audio seems to drop out completely. I would even be willing to pay a little (really a little) if we could get it worked into the software, maybe others would too. I do have a process but it's not very good and it involves exporting the audio then speeding it up with ffmpeg, then bring it back in, but that's so much extra work that I almost never do it. Does anyone know if this feature is being talked about?

You may want to check out this thread viewtopic.php?f=272&t=129744 about creating a transcode job profile in Kdenlive for speeding up source footage. I now regularly use this for my screencast projects. While in my projects I do a separate voice over recorded with studio equipment in audacity, please see later posts in this thread about which parameters to add for speeding up audio also.
