Yes, I'm using both those tools now, and they work fine for me. But I need to come up with an easy-to-use cross-platform system for an interviewing workflow with limited internet. My idea was to use digikam, since it has such explicit support for importing media from SD cards. I could then ask the users to select the photos and videos they want for the project (crop the photos, etc.)<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The next step of the process needs just the audio, or a super-low-quality video (e.g 1 fps), so the files can be quickly uploaded to a website, where computers and people can transcribe and translate the content. That's the step I'm trying to solve right now. I'm using kdenlive for some of the photo/video selection, but it lacks customized batch jobs, customized proxies (which prompted this question), and extracting audio puts the .flac file in the same directory as the video, etc. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I'm trying to avoid asking the users to install ffmeg, so thought there might be a way to set something in a batch queue manager to create the lower-quality videos or extract the audio, and skip kdenlive for this part.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I use Ubuntu, but others who want to use this use Windows and Mac.
