Sometimes I feel too lazy to read them from the tablet. I thought It would be better If I can be able to create a video from PDF files and watch it in a big screen devices like a TV or a Computer. Though I have a little working experience with [**FFMpeg**][1], I am not aware of how to create a movie file using it. After a bit of Google searches, I came up with a good solution. For those who wanted to make a movie file from a set of PDF files, read on. It is not that difficult. + +### Create A Video From PDF Files In Linux + +For this purpose, you need to install **" FFMpeg"** and **" ImageMagick"** software in your system. + +To install FFMpeg, refer the following link. + +Imagemagick is available in the official repositories of most Linux distributions. + +On **Arch Linux** and derivatives such as **Antergos** , **Manjaro Linux** , run the following command to install it. +``` +sudo pacman -S imagemagick +``` + +**Debian, Ubuntu, Linux Mint:** +``` +sudo apt-get install imagemagick +``` + +**Fedora:** +``` +sudo dnf install imagemagick +``` + +**RHEL, CentOS, Scientific Linux:** +``` +sudo yum install imagemagick +``` + +**SUSE, openSUSE:** +``` +sudo zypper install imagemagick +``` + +After installing ffmpeg and imagemagick, convert your PDF file image format such as PNG or JPG like below. +``` +convert -density 400 input.pdf picture.png +``` + +Here, **-density 400** specifies the horizontal resolution of the output image file(s). + +The above command will convert all pages in the given PDF file to PNG format. Each page in the PDF file will be converted into a PNG file and saved in the current directory with file name **picture-1.png** , **picture-2.png** … and so on. It will take a while depending on the number of pages in the input PDF file. + +Once all pages in the PDF converted into PNG format, run the following command to create a video file from the PNG files. +``` +ffmpeg -r 1/10 -i picture-%01d.png -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4 +``` + +Here, + + * **-r 1/10** : Display each image for 10 seconds. + * **-i picture-%01d.png** : Reads all pictures that starts with name **" picture-"**, following with 1 digit (%01d) and ending with **.png**. If the images name comes with 2 digits (I.e picture-10.png, picture11.png etc), use (%02d) in the above command. + * **-c:v libx264** : Output video codec (i.e h264). + * **-r 30** : framerate of output video + * **-pix_fmt yuv420p** : Output video resolution + * **video.mp4** : Output video file with .mp4 format. + + + +Hurrah! The movie file is ready!! You can play it on any devices that supports .mp4 format. Next, I need to find a way to insert a cool music to my video. I hope it won't be difficult either. + +If you wanted it in higher pixel resolution, you don't have to start all over again. Just convert the output video file to any other higher/lower resolution of your choice, say 720p, as shown below. +``` +ffmpeg -i video.mp4 -vf scale=-1:720 video_720p.mp4 +``` + +Please note that creating a video using ffmpeg requires a good configuration PC. While converting videos, ffmpeg will consume most of your system resources. I recommend to do this in high-end system. + +And, that's all for now folks. Hope you find this useful. More good stuffs to come. Stay tuned! + + + +-------------------------------------------------------------------------------- + +via: https://www.ostechnix.com/create-video-pdf-files-linux/ + +作者：[SK][a] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]:https://www.ostechnix.com/author/sk/ +[1]:https://www.ostechnix.com/20-ffmpeg-commands-beginners/ +[2]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=reddit (Click to share on Reddit) +[3]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=twitter (Click to share on Twitter) +[4]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=facebook (Click to share on Facebook) +[5]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=google-plus-1 (Click to share on Google+) +[6]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=linkedin (Click to share on LinkedIn) +[7]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=pocket (Click to share on Pocket) +[8]:whatsapp://send?text=How%20To%20Create%20A%20Video%20From%20PDF%20Files%20In%20Linux%20https%3A%2F%2Fwww.ostechnix.com%2Fcreate-video-pdf-files-linux%2F (Click to share on WhatsApp) +[9]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=telegram (Click to share on Telegram) +[10]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=email (Click to email this to a friend) +[11]:https://www.ostechnix.com/create-video-pdf-files-linux/#print (Click to print) From 4f073524af507a310953c53c7360bc4c9592fd24 Mon Sep 17 00:00:00 2001 From: darksun Date: Sat, 6 Jan 2018 13:14:16 +0800 Subject: [PATCH 2/2] add done: 20171004 How To Create A Video From PDF Files In Linux.md --- ...04 How To Create A Video From PDF Files In Linux.md | 10 ---------- 1 file changed, 10 deletions(-) diff --git a/sources/tech/20171004 How To Create A Video From PDF Files In Linux.md b/sources/tech/20171004 How To Create A Video From PDF Files In Linux.md index 2cd028892a..27aa32dc77 100644 --- a/sources/tech/20171004 How To Create A Video From PDF Files In Linux.md +++ b/sources/tech/20171004 How To Create A Video From PDF Files In Linux.md @@ -87,13 +87,3 @@ via: https://www.ostechnix.com/create-video-pdf-files-linux/ [a]:https://www.ostechnix.com/author/sk/ [1]:https://www.ostechnix.com/20-ffmpeg-commands-beginners/ -[2]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=reddit (Click to share on Reddit) -[3]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=twitter (Click to share on Twitter) -[4]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=facebook (Click to share on Facebook) -[5]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=google-plus-1 (Click to share on Google+) -[6]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=linkedin (Click to share on LinkedIn) -[7]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=pocket (Click to share on Pocket) -[8]:whatsapp://send?text=How%20To%20Create%20A%20Video%20From%20PDF%20Files%20In%20Linux%20https%3A%2F%2Fwww.ostechnix.com%2Fcreate-video-pdf-files-linux%2F (Click to share on WhatsApp) -[9]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=telegram (Click to share on Telegram) -[10]:https://www.ostechnix.com/create-video-pdf-files-linux/?share=email (Click to email this to a friend) -[11]:https://www.ostechnix.com/create-video-pdf-files-linux/#print (Click to print)
