[solved] pitivi - Output File is Bigger Than Input File

- I create a new, empty pitivi project
- I import into the project an MP4 file of size 8MB
- I do Render and choose MP4 as the container format
- An hour later, I get an output MP4 file of size 34MB

How come the output file is bigger than the input file?

Google returns some results which suggest that I should try using the H.264 video codec.  I attempted to install that using the following:

sudo pacman -S openh264

That appeared to succeed, but in the pitivi UI I don't see any option to use H.264.  Is there further configuration that I would need to do?

Ultimately I want to add subtitles to this video but I need to solve the above problem first.

Re: [solved] pitivi - Output File is Bigger Than Input File

With help from the pativi Matrix forum, I fixed this with one of the two commands below, I don't know which one:

sudo pacman -S gst-plugins-bad
sudo pacman -S gst-plugins-ugly

I had to restart pativi.
