FFmpeg produces great ogv files under Xenial:

Free codecs: How to use FFmpeg to convert my mp4s to ogv under Xenial?

But I would like to use the gui WinFF to produce these files, and WinFF has no presets for this purpose. How can I do this?

Best Answer

A default installation of WinFF under Xenial:

sudo apt-get install winff ffmpeg

has no presets to produce ogv files with Theora video and Vorbis sound. A great omission IMHO.

You can rectify this omission by producing a text file called ogv.wff on your Desktop and placing the following contents into it:

<?xml version="1.0" encoding="utf-8"?>
<presets> 
  <OGV>
    <label>Theora encoding with Vorbis sound</label>
    <params>-c:v libtheora -qscale:v 6 -c:a libvorbis -qscale:a 5 </params>
    <extension>ogv</extension>
    <category>My Presets</category>
  </OGV>
</presets>

Save this file, close it, right click on it and select: 'Open with WinFF' and this is enough to save your new preset in ~/.winff/presets.xml.

And now you can enjoy producing great quality media files with 2 completely free codecs!

Arista Transcoder

or from command line

sudo apt-get install arista -y

You can use this software, that I always use and I think it's really good. To convert an ogv file to mp4 you should choose any Sony device.

Ubuntu – How to add and/or keep subtitles when converting video

Softsubs

MP4 supports streaming text format subtitles, but playback support for this among players and devices is not universal.

Basic example using default stream selection behavior while stream copying the audio:

ffmpeg -i input.mkv -c copy -c:s mov_text output.mp4

Example to stream copy all of the video and audio streams, convert the all text based subtitle input streams (SRT, ASS, VTT, etc) to the streaming text format, and set the language for the first two subtitle streams.

ffmpeg -i input.mkv -map 0 -c copy -c:s mov_text -metadata:s:s:0 language=eng -metadata:s:s:1 language=ipk output.mp4

Same as above but re-encode the video and audio to formats compatible with the MP4 container (H.264 video:

ffmpeg -i input.mkv -map 0 -c:v libx264 -c:a aac -c:s mov_text -metadata:s:s:0 language=eng -metadata:s:s:1 language=ipk output.mp4

Same as above but use the -map option to choose the first video stream, second audio stream, and third subtitle stream:

ffmpeg -i input.mkv -map 0:v:0 -map 0:a:1 -map 0:s:2 -c:v libx264 -c:a aac -c:s mov_text -metadata:s:s:0 language=eng output.mp4

Hardsubs

Text based subtitle format inputs

Use the subtitles filter to "burn-in" text based subtitle formats (SRT, ASS, VTT, etc). Note that this requires re-encoding, so it will by much slower than using softsubs.

Basic example using default stream selection behavior while stream copying the audio:

ffmpeg -i input.mkv -filter_complex "subtitles=input.mkv" -c:a copy output.mp4

Example to use the third video stream, fifth subtitle stream, and first audio stream:

ffmpeg -i input.mkv -filter_complex "[0:v:2]subtitles=input.mkv:si=4[v]" -map "[v]" -map 0:a:0 -c:a copy output.mp4

Example for a separate subtitle input file (your-subtitles-file.srt):

ffmpeg -i input.mp4 -filter_complex "subtitles=your-subtitles-file.srt" -c:a copy output.mp4

Image based subtitle format inputs

Use the overlay filter. This example will overlay the fourth subtitle stream over the second video stream, and stream copy the seventh audio stream:

ffmpeg -i input.mkv -filter_complex "[0:v:2][0:s:3]overlay[v]" -map "[v]" -map 0:a:6 -c:a copy output.mp4
