http://www.linuxandlife.com – Making a video in slow motion is actually nothing special since there are plenty of video editing tools with a lot of cool features for you to use. However, if you just want to create a short video in slow motion to upload it to youtube, you can run a simple command in the terminal with the help of mencoder. Mencoder is a command line video decoding, encoding and filtering tool and it can convert every format that can be run in MPlayer. To use mencoder, you will need to install it first. In Ubuntu and other Debian-based distro, the command to install mencoder will be: sudo apt-get install (Distributions)

I just bought a Kindle Fire HD and it's pretty cool to watch movies with it. However, unlike with VLC, I dont know how to open the subtitle files with the built-in movie player of the tablet. Therefore I had to add the subtitles to the videos first before transferring them to the tablet.

Hello!

I've tried reading through a number of threads on here about adding subtitles hard into the video stream with mencoder, but most of them are people asking how to do it or having problems. So apologies if this has already been asked somewhere, but I haven't found it yet.

I'm using mencoder to record the webcam. Is it possible that play the converted video at the same time?

I could use mplayer to play the output video while converting. Or is there any way to start mplayer at the same time when mencoder starts?

Now I have file .mkv (included 3 streams)

1.Video 2.Audio 3.Subtitle

I want to convert from MKV to MP4 by Mencoder Program with requirement on list

1.subtitle and video blend together in 1 stream 2.video same input quality 3.file target size same input too

How to write command for render this project ?

ps. Sorry for bad English

Thank you

Hello

Anyone got any ideas on how i can get mencoder to install on 12.10 ?

Software center says it is broken - Gdebi says it needs libavcodec that is older than the one already installed.

What would forceing it to install from command line to system stabiliation ?

Thanks in advance for any help.

‘Let’s have a look at a rather simple mencoder command that should create a WMP-compatible MPEG file:

I'm converting DVD media to a MKV format video with mencoder:

mencoder dvd://4 -o output.mkv -oac mp3lame -ovc x264 -x264encopts crf=20:8x8dct:frameref=4:bframes=3:b_pyramid=normal:weight_b

But the output from file output.mkv indicate it's AVI format ?

RIFF (little-endian) data, AVI, 720 x 576, 25.00 fps, video: H.264 X.264 or H.264, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)

[Q] Video - Slow Motion quality 11 weeks 23 hours ago

Question guys - to enable you to slow certain scenes in a video you need to select the slow motion video scene...fair enough.

Should this in turn reduce the quality of the video?

I could be wrong, but before I went to a custom ROM, I am fairly sure the video quality remained the same as normal. Now as soon as I record in slow motion, it reduces the quality.
