  1. You recommend Format Factory.
    That’s fine but what if people are on a Mac?
    I went to Softonic’s website to check and it yep, they say, somewhere along, for mac, go here.I went there and was presented with 3449348 other pieces from all around the world but nothing to do with format factory.
    That’s really funny.

  2. HandBrake is my favorite video compressor for mac. Well, I am looking for alternative apps for my windows pc and I got the best solution.

  3. I have used WinX Video Converter before. When I import a 700MB video into this software, I want to export a 200MB video. In fact, this software does this, but the exported video is completely distorted. I can hardly see the face of the person. I found a similar software called wonderfox video converter. This software has an internal setting that keeps the picture clear. I think it is very good.

  4. Everything I need is to make from video with 500 MB size something like 100 MB. I have no clue about codecs, frames, gob size… I’ve tried Avidemux but even I have doctors degree at technican university, I spent 6 hours to work on the video from my dron and the result is MKV with 1 GB. Why should I read such articles as is this one?
