hmm sweet .. how long does it take to transcoding my videos to MP4 on 100 movies ? Each movie rufly 700mb-1.2gb. Also any sujestions on program for transcoding all my videos to MP4 ? I use windows 7 and 10 and ubuntu.
This is SOO much easier on Linux. So that is good news that you have Ubuntu. Not my prefered distro, but it will be easy to work with. Use Handbrake to transcode to MP4. MP4 also has the advantage of playing on pretty much everything at this point. However you will need to add a PPA as the one included with Ubuntu doesn't do something, I forget what though. Google Stebbins Handbrake PPA, it will come up. You will want to use EasyMP3Gain as a GUI for AACGain. Also installed MP3 gain. Google Martin Wimpress Audio Stuff PPA for aacgain and mp3gain.
As for the transcoding, you can just queue this stuff up and let it run. It will just depend on the speed of your PC. I originally did most of my videos on an I5 and just let my PC run until it was done. MP3gain and AACgain you'll find is much more finicky, will work and will work with large amounts of files, but you can't touch anything or move the mouse etc while its working. If you do you run the risk of it erroring out. Let it process, then apply the changes, then close out. If the data corruption error pops up I close out of it and start over.
Its not that bad, I just checked my video folder, and its just over 4000 videos now that I've transcoded, which includes resizing, and then run through aacgain to normalize. All my MP3s are normalized too that way everything is the same volume level
