It's probably just that the audio in your input file is in a codec that's incompatible with the mp4 container. But it's hard to know from here without digging deeper into your source file. The last one about track 1 (which is most likely audio) points to an issue however. The errors are probably something you can ignore. That way any special character that could mess with things can no longer do harm and no other escaping with backslashes is required. If you want to type manually then simply enclose both filenames with single quotes like this:įfmpeg -i 'input file.mkv' -c copy '/Users/Heinz/Desktop/output file.mp4'. (it now should show ffmpeg -i /full/path/to/yourinputfile/inputfile.mkv -c copy /full/path/to/yourinputfile/outputfile.mp4).press backspace key a few times (that's the key above Enter with the left pointing arrow) to delete the filename "inputfile.mkv" and then type the new filename w/o any spaces (keep it simple).(it now should show ffmpeg -i /full/path/to/yourinputfile/inputfile.mkv -c copy /full/path/to/yourinputfile/inputfile.mkv).drag your input file onto the Terminal window again.type -c copy (important spaces before -c and after copy).(it now should show ffmpeg -i /full/path/to/your/inputfile.mkv).drag your input file onto the Terminal window.type ffmpeg -i (important there's a space after the i!).If that prints a long list of options then you're good to go. a filename like foo bar.mkv would be converted to foo\ bar.mkv to get the space out of the way, else the command would look for foo and assume bar.mkv is another parameter. You also could drag the file onto the Terminal window (after typing ffmpeg -i and it should be escaped properly, e.g. :) Of course, it's not something we can know beforehand when reading your opening post.ĭoes your path/filename has spaces or some other special characters? Typically when we "pros" type something in Terminal we use tab completion and things get "escaped" automatically. It's too bad Apple's built in hardware doesn't compare yet to software compression results.Looks like you have a tiny learning curve ahead as you seem to never have used any command line applications from Terminal. You'll get higher quality and lower file sizes. Permute seems here to stay, though, so I look forward to seeing them do that optimization work.Īlso ps/hint: If you're shrinking movie files, don't let Permute use the included hardware compressor. If they just sit there and keep tweaking, they shuodl be able to beat the rest in this class of software. I really think they need to work through these more. Sadly, the one thing I don't like is their compression settings too much. JPEGMini also tends to make somewhat better JPGs. ![]() If you really sit there with Handbrake, you can make massively small files with neglible quality loss. I can also get much smaller movie files with Handbrake, without even much fuss. It's just so easy, I mostly find myself using OptiMage these days. I also shrink some h.264 and h.265 movie files, especially family outings which tend to be huuuuge.Īside from lack of h.265 support, OptiMage compresses smaller files and at higher quality than Permute. I covert mostly PNG and JPG files to smaller versions, including HEIC. I really liked Permute, until I found another piece of software called OptiMage. Increase volume, rotate video, change its resolution, flip it and so on!Ĭompression settings need tweaking & refinement Customizations - Customize the presets, or just that particular conversion. With Permute 3.2 or later, you can also convert images into text! Want to create a DVD? No problem, Permute can do that too. Versatile - Videos, audio, images - Permute can handle it all. Insanely Fast - Permute can utilize as much of your computer as possible to get stuff done ASAP. Easy to Use - What could be easier? Drag & drop a file, select target format and go. ![]() Permute includes icon view that allows you to see thumbnails of whatever you are working with. Beautiful UI - See what you are converting. ![]() Video, audio and image files come in many different kinds and shapes, but sometimes you need a specific format since your iPad or DVD player won't play that video. Permute is a versatile tool that allows you to convert video, audio and images files into different formats, increase volume, merge them and much more!
