Hi,

4MLinux 26.0 (to be released at the beginning of September 2018) will come with full support for VP8/VP9/AVC/HEVC video encoding.
I was having a really good time trying to write modern presets for quite old Hyper Video Converter:
http://hypervideoconve.sourceforge.net/

.

Go to Menu > Multimedia > Let’s edit > HyperVC
Right click on Manage Profiles and choose ffmpeg.

Available presets:
DivX AVI
Xvid AVI
FLV -- H.263 encoding
FLV -- H.264 encoding
MP4 -- AVC encoding
MP4 -- HEVC encoding
WebM -- VP8 encoding
WebM -- VP9 encoding
Theora/Vorbis as OGG
Theora/Vorbis as MKV
Theora/Opus as OGG
Theora/Opus as MKV
3GP for mobiles -- small
3GP for mobiles -- normal
3GP video -- CIF format
MP4 optimized for YouTube
Extract audio as MP3
Extract audio as M4A
Extract audio as OGG Vorbis
Extract audio as OGG Opus
DVD - PAL -- 1800kbit
DVD - NTSC -- 1800kbit
HD to DV -- for easier editing

Note:
These are (rather simple but) modern presets: constant video quality with resultant bitrates.

.

After many hours, I was finally able to compile legacy version of MEncoder and to force it to produce YouTube-like video formats.

Install MEncoder: Menu > Extensions > MediaApps > Players > MPlayer
Go to Menu > Multimedia > Let’s edit > HyperVC
Right click on Manage Profiles and choose mencoder.

Available presets:
AVI for web -- 360p
AVI for web -- 480p
AVI for web -- 720p
AVI for web -- 1080p
FLV for web -- 360p
FLV for web -- 480p
FLV for web -- 720p
FLV for web -- 1080p
MP4 for web -- 360p
MP4 for web -- 480p
MP4 for web -- 720p
MP4 for web -- 1080p
WebM for web -- 360p
WebM for web -- 480p
WebM for web -- 720p
WebM for web -- 1080p

Note:
These are (rather simple) old-school presets: constant bitrates with resultant video quality.
