I want to convert AVI to MP4, somebody recommend me kigo video converter ultimate for mac, i didn't use it. Anyone know it, give some info, quickly?
There are also quite a number of online video converters as an alternative to ones you have to download and install. The downside of online converters is that you usually have to upload your video, then it gets processed on their servers and then you have to download it again. You never know if they really delete your video either. I've used some for smaller videos and they worked OK, like https://cloudconvert.com/mp4-to-anything for example.
However there is also a type of hybrid converter, which I personally prefer. It doesn't upload videos, instead it processes them on your computer but it runs inside the web browser, so no need to download and install (and pay for!) software. I've used it a couple of times and it's worked well for me, see clipchamp.com.
