Due to a limitation which prevents screenshots from being taken while DVD Player is running, grabbing frames from movies is a hassle. With a little trickery (or a different video player), that problem can be solved.
Acala Screen Recorder - is a free video Screen Capture, Screen recording tool used for recording Screen activity into standard AVI video files. If you move the cursor, launch a new program, type some text, click a few buttons, or select some menus - anything that you see on your Screen - Acala Screen Recorder Free will be able to record all. Free video capture software is very useful for capturing high-quality videos that you performed on your device like a computer, mobile phone, or tablet, and meanwhile, you don't want to spend much money on buying a paid recorder.
You've probably seen the error before: 'Screen grabs are unavailable during DVD playback. Please quit DVD Player first.' Ugh… what an inconvenience. But while attempts to take a screenshot via normal methods (Command+Shift+3, for example) produce this stern warning, there is a way to get around it.
- If you haven't already done so, launch DVD Player to play your movie. Go to the exact frame you want to capture and then pause playback.
- Open Terminal (Applications > Utilities) and copy & paste the following command:
- When you hit Enter/Return on your keyboard, the mouse cursor will change from an arrow to crosshairs. Press Command+Tab to switch back to DVD Player without making any clicks.
- Press the spacebar and hover over the DVD Player window. The entire frame should be highlighted, so all that's left to do is click on it.

A new image file should instantly show up on your Desktop. The only downside to this approach is that you'll need to open your screen grab in Preview to crop off the top and bottom parts of the window. If you'd like to avoid all of this trouble to begin with, there is indeed yet another way to capture DVD screenshots – although not with Apple's built-in DVD Player.
Hopefully you have already installed or at least heard of the invaluable open source media player known as VLC. If not, get to it! It can play just about any video or audio file you throw at it, so it's guaranteed to come in handy as some point. In fact, this is one of those times. Since movies playing in VLC are not locked down quite like they are in DVD Player, taking screen grabs is a breeze. Just go to Video > Snapshot in the menu bar and the image will pop up right on the Desktop! It's way easier than messing with DVD Player's nonsense. So why didn't I just start off with that? Because it's fun to learn little hacks and workarounds to problems! …Right?
Although no longer near the top of acquisition options, screen capturing is one of those tasks that when it is needed, it pays to have prepared your capture environment beforehand.
Screen capturing is fraught with difficulties. The main issue now, from a forensic image analysis point of view, is that many players change the encoded data for their display purposes. This can severely affect the video's ability to be analyzed correctly for restoration or enhancement. As a result, relying on that captured video may be unwise in certain circumstances.
Amped FIVE‘s DVR Screen Capture is there to be used when required, and it is still required! Not just for capturing those formats/players that were designed by an ill-informed developer, but for identifying differences or, validating time overlays. I discussed differences in a recent post.
Another reason is that you may just need to quickly show that video to someone… and they can't install the proprietary player, or it has no export function.
The simple user interface starts with detailing your Output File. This is followed by your Output Format. The decision of whether to apply compression will all come down to why you are screen capturing in the first place. To verify the size of player window, time overlay information or, to send a quick clip for someone to preview, using a lossy compression format may be acceptable.
The next three boxes are the ones I wish to concentrate on.
The Capture Display field identifies how many monitors are connected and their resolutions. The Capture Region specifies what is to be captured. Lastly, the Capture Frame Rate gives options for the Capture Frames per Second.
Before you need to use this tool during an investigation, it is worth spending some time to test your setup. If you have a large resolution display, with multiple monitors, that's a lot of image data to process. Having an idea of what to change, and when, will help you when you need it.
As you start capturing, using the Start Capture button, you will notice the Frames captured information increases. If the data is just too much to handle, you will also see the number of Frames lost go up! We don't want to lose frames!
Here are a few general tips, and ideas on preparing your system for screen capture, ensuring you can capture the video with no lost frames.
Analyze the player that is being used
Do you really need to screen capture? Check out every button in the interface. Are there any right click options? Is there an updated player, or client, with extra functionality. If you don't need to screen capture – don't! If there is no other option, the player may have settings for how the video is being displayed. Deblocking, reduced frame rate, skipping B frames, deinterlacing; these are all options that, if used, will affect your capture.
Analyze the frame rate of the video you are capturing

If it's only playing back at one fps, capturing at 25 fps is way more than required. A general rule of thumb is to capture twice as many frames as are being displayed. This, obviously, has a few issues when you have a 25 or 30 FPS Video. Having to do this though is getting much rarer, as high frame rate videos can usually be processed without resorting to screen capture.
Remember, after capture, you can remove any duplicates using the Remove Duplicates filter.
Understand the purpose of the screen capture

You don't need to capture full uncompressed, at full frame rate, every time. On many occasions, you need to send the clip to someone to assist in telling the story of an event. The fact that it is further transcoded, or has a reduced frame rate, is irrelevant as long as the evidential worth is maintained and the meaning of the video has not been changed.
If you need to analyze the overlaid timecode, then you may not need to capture the whole video. Capture a few seconds near the start, in the middle and at the end.
If it is for analysis, then understand the limitations and attempt to verify any conclusions surrounding size and format with the actual DVR settings or manufacturer's documentation.
Adjust your graphic properties
If you refer to the graphic near the top of this post, you will see that if I was capturing the entirety of my first monitor, it would be 2560px x 1440px. That's a lot of pixels. I also have a second monitor attached. The graphics card is still outputting to that monitor, even though FIVE is only using the first.
One of the quickest ways to reduce the load of the screen capture process is to reduce the amount of data being processed by the graphic card.

By disabling the second monitor and reducing the resolution on the first, the capture frame rate can easily be doubled.
Only capture what's needed
Do you need the entire player interface, or just the player window and date/timecode? Capture just the area you need. Don't worry about the rough edges of your capture area; you can crop them out later by using the Crop filter.
It's important to state here that you don't want to be making your video player/window smaller just to make your capture smaller. The video should be presented by the player at its original size (If you can establish that).
Adjust Frame Rate
It is sometimes possible to play a video slowly and then capture it at this speed. The speed can be corrected later through the use of other filters. This is particularly useful when you just need image data and timing is not of importance.
Close unnecessary programs and processes
The more work Windows is doing, the higher the chance that frames may be lost during capture. Programs that relate directly to the display, or Windows Explorer, can disrupt the capture process and thereby cause lost frames.

I hope that some of these hints and tips help you in your screen capturing tasks. Take a look at another recent post on The Report, where screen-capturing the player, was used to assist in note taking.
