Last week, I was shooting videos on my old phone—all in .mov format, but YouTube wouldn't accept them without recompression, and they were ravenously eating up disk space. I tried free converters: one threw an error halfway through the file, another added watermarks, and a third simply slowed me down. Finally, the website
https://www.movavi.com/video-convert...ov-to-mp4.html helped me — I uploaded a bunch of files, chose a YouTube preset, and in 15 minutes I had perfect .mp4 files with no loss in quality or any other crap. Now I'm wondering why bother with glitchy alternatives when movavi really saves the day in these situations, quickly and for free.
