However, if you still think that your file is too large, you can correct its output size in Freemake before the transcoding. MPEG-4 is widely used because multimedia encoded with this codec occupies less space on a hard drive than the very same clips with other codecs. Select MPEG4 codec and convert the video. Add your MP4 video into the freeware, choose the 'to MP4' option and open the video settings.
If your MP4 video has another than MPEG-4 codec (e.g., h.264), you can easily change it with Freemake Video Converter. Then just follow the guidelines above to save YouTube to MPEG-4. What you need to do is to copy YT content link and insert it into the too via the “Paste URL” button. You don’t need to use a special downloader anymore. Freemake program can encode both offline clips and YouTube media.
