Very consistent
I’ve used this on hundreds of old video files, and have received error files on about five. (These were very, very old .rv files). The converted files show no reduction in quality. More recent files, especially .mkv files, are converted incredibly quickly. Most .avi and .wmv files, however, will take some time — maybe 30 minutes or so on an old Mac Pro. As the app can run on batches of files, it’s not a problem to load it up and let it run over night.
Now all my videos are easily playable on all my iOS devices.
