When I Converted from WMV to MP4 the file size went from 4Mb to approx 8Mb. What would be a reason(s) for this? Thanks
MP4 is compressed and usually outputs small file sizes. 8MB for a video file really isn't that big at all so it shouldn't be an issue. It all depends on the program you use and the codec settings. The reason is most likely the settings when encoding the video to preserve detail.
