Thanks very much to Ed, Doug and Samuel. I installed and used handbrake with the following: HandBrakeCLI --gain 20 -i Worksheet13.mp4 -o temp.mp4 and while not a masterpiece any longer, it will pass, especially for those who did not know what the silent treatment conveyed.... Thanks to Sam also, this would have been an easier option. I will try it but since I have uploaded and there is a limit on the MB of files I am allowed to have (and no way to delete files up on Canvas), I will not upload further. As always, this is such a knowledgeable and helpful group! NO wonder I have stuck to Fedora from FC1! Many thanks again and best wishes, Ranjan On Wed, 1 Apr 2020 22:04:46 -0700 Samuel Sieb <samuel@xxxxxxxx> wrote: > On 4/1/20 8:44 PM, Ranjan Maitra wrote: > > I apologize for this OT question but I have just finished recording an hour-long masterpiece for my class. However, the volume appears to be really low. I don't know why this happened, but long story short, I really do not want to do this again, so I was wondering is there any software on Fedora 31 that will allow me to edit the mp4 to increase the volume. I doubt that this is that easy, but I still thought that I would give it a try. > > ffmpeg is a great tool for adjusting media files. > https://trac.ffmpeg.org/wiki/AudioVolume describes only for a .wav file, > so here's what should work for yours: > ffmpeg -i input.mp4 -c:v copy -filter:a "volume=1.5" output.mp4 > That should just the video directly and adjust the volume by 150%. > Adjust as necessary. > _______________________________________________ > users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx > Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx -- Important Notice: This mailbox is ignored: e-mails are set to be deleted on receipt.
