HOW TO PLAY VIDEO WITH VLC FRAME BY FRAMEBefore I go through steps a video can be play with VLC frame by frame, it would be better to introduce Video Lan Player which was formerly continued as an open source educational project by videolan.org. It was then thrown out to the community of open source software developers, which persistently added numerous features and aspects that an industry standard media player should unify in single package one of which is video frame manipulation i am going to discuss. In addition to that it was brought absolutely free even the efforts made were so huge. Our main focus here is to discuss one of those preeminent features which let you have a control over the playing of a video by VLC frame by frame so that you can extract frames from video.

If you want to personally perform the same function I am doing, along the way in this article, it would be better to have VLC pre installed in whatever the operating system you are familiar with.

‘E’ Is defined as a default shortcut key to play videos on VLC frame by frame when the VLC player is deployed for the first time after its installation. But VLC media player gives you a freedom to configure your own shortcut key for any function like manipulating video frame in this case. If you wish to do so navigate to a menu Tools > Preferences > Hotkeys, and a new window with huge list of keyboard shortcuts would be in front of you.

Now go through that list and find out where the Next Frame in the list is located. Fortunately every shortcut key name is sorted in alphabetical order, so it is not that difficult to quickly find out shortcut keys in the list. Once you double click the shortcut name, a new popup dialog window would suggest you to press the new key or a combination of keys for the shortcut you want. After that Pressing save button would permanently write the changes to the configuration.  Next time when you wish to run video in VLC frame by frame the new shortcut key would be available to use.

As I already told you that each function inside VLC player can be done with two methods.  This time I am going to do the same function with a dedicated button that is assigned to run video frame by frame. But that button should be activated first to appear in playback toolbar. Clicking Customize Interface option under Toolbar menu will open Toolbar Editor Window containing each and every control you see below the video being played.

From that list choose Frame By Frame button control and drag it on line 1 or 2 as shown in the picture.  Now close the toolbar editor and frame by frame button would appear in front of you along the other playback controls.

To take snapshot you can either use free dedicated snipping tool to capture the screenshot of frame or you can use the built-in VLC Take Snapshot control as shown in steps defined below.

Once you reach the video frame you can press Shift + S hotkey to extract frames from video.

Also here is an alternative way to grab a snapshot of video frame via clicking Take Snapshot option under video menu.

Another very easy and comfortable way to take snapshot of the video currently being played currently is to go to the Video menu and then navigate to Take Snapshort and click on it.

You may also notice that while taking snapshot of each video frame, if it is successful, a small thumbnail of the image along with entire directory path where the file is saved, would be shown to you instantly and then will fade away in a moment. See picture below:Extract frames from video - Video Frame Thumbnail Shown

VLC automatically save that snapshot to your default video folder which is C:\Users\username\My Pictures both on Windows 7 and Windows XP?  If you are Mac user all the snapshots would be saved to the Desktop and if you are a Linux it would be saved in the home folder of that particular user.
