The occurrence of self-healing in microcapsule based polymer composite systems has been demonstrated using fracture experiments3,4,5,6, showing as much as 75% recovery of the original fracture toughness and a high healing efficiency reaching values of up to 90%. The average critical fracture load required to propagate a crack in an undamaged self-healing polymer was found to be 20% higher than the average value for neat epoxy samples containing no microcapsules or catalyst3. The inherent toughness of the epoxy is therefore shown to increase with the addition of microcapsules/catalyst. This microcapsule induced toughening has been observed to have a strong dependence on the size and density of the embedded microcapsules4. Furthermore, the presence of the microcapsules has been shown to significantly decrease the fatigue crack growth rate and increase the fatigue lifetime (more than 100 times increase at low K/K1c ratios)5. Given that the microcapsules impact on the stiffness and strength of the polymer it is essential to optimize their size, spacing and activation to effect healing at microcapsule loadings that are as low as possible.
A limitation of using conventional absorption contrast X-ray tomography is that the epoxy and the microcapsules have very similar X-ray absorption coefficients making the capsules difficult to differentiate from the matrix. Here we exploit phase contrast and an associated phase filter during reconstruction to significantly improve their detectability. The sample was mounted in a tension-compression mechanical testing rig which could be accommodated on the synchrotron X-ray beamline such that the filling of the crack could be monitored by X-ray CT during loading. This has allowed us to establish a quantitative picture as to the activation sequence over time; in particular how near the microcapsules must be to the crack, how they progressively release their contents, and the extent to which this fills and repairs the crack.
Time-lapse photography is a technique that takes photos or videos at a lower frame rate and then plays them at a normal or faster rate. In a time-lapse video, the process of slowly changing objects or scenes is compressed into a short period of time, presenting a wonderfully speeded-up picture that is usually invisible to naked eyes. It's commonly used in shooting day to night transitions, urban scenes, natural scenes and many more.
However, not all cameras have a time-lapse function. Therefore, you need to take a series of photos and combine them into a video using time lapse software. And this article has carefully picked up 14 best time lapse editing software for your reference. Let's Explore!
With a smooth and simple UI, VideoProc Vlogger offers a great speed-changing feature to help you make a time-laspe video. It can emulate the time lapse or hyperlapse effect by increasing the playback speed of original videos. What you need to do is to navigate to where your video is located and import your video to the program, alter the speed of your video, and mute all video tracks.
Arguably one of the best time lapse software, Adobe Premiere Pro is professional and feature-wise software to create stunning time lapse videos. It can work with a wide range of file formats and involves tons of customizable tools, as well as third-party plugins to let you fly through your workflow.
Making a time lapse video in Premiere Pro is simple. Create a new bin and import all your photos to the bin at the get-go. To ensure the video playing without any glitch, you will need to sort the photo files by name. Next, you will create a sequence with proper video settings and add all your material to the timeline. Then you will be able to get a smooth and nice time-lapse video.
Deemed as the most powerful image editing program, Adobe Photoshop, virtually, can be also used to create videos. Though this ability is not as powerful as it does in Premiere Pro, it still is a good solution to compile a high definition time lapse sequence. The sweet spot is that you are able to modify the ISO, white balance, exposure, contrast, saturation, etc. of images in Raw format directly in Photoshop, so that you can yield the best result of time lapse videos.
iMovie is a Mac-only photo and video editing software that gives you highly functional and cool capabilities like theme-based templates, cropper, speed alternation, text layer, image stabilization and more. And creating a time-lapse video in iMovie takes much time than other tools in this list, largely because iMovie doesn't edit videos frame to frame in the timeline and the minimum duration in iMovie is 0.1 second, which is nearly 10 frames. Therefore, you need to export the time-lapse sequence first and speed up the clip later on.
Putting into the open source league, Shotcut is widely considered one of the best time lapse video editing software at no cost. Though it is primarily geared toward video editors expecting to create videos, Shotcut is also packed with a number of key image editing features for making time lapse videos from photos.
LRTimelapse is a professional and flexible software designed for making time lapse videos with the integration with Adobe Lightroom, Adobe Camera RAW, and Adobe After Effects. The real benefits of it are that it can remove ugly and distracting flickering in your image sequence and connect all the images with a smooth change in white balance, exposure, highlights, temperature, etc. in one click.
How to timelapse a video with motion? Generally, you can use camera sliders to shoot smooth motion control time-lapse video. However, in addition to the price, the heavy and bulky slides could be prohibitive to some. Don't have one? No sweat. You can use Panolapse to motion to time lapse videos in a minute. More so, it can work with fisheyes lens and 360° panoramic images.
Time-Lapse tool is a Windows-only software dedicated to making time lapse videos by combining multiple still images. Once you've imported your images, you will find there are many options to play with, covering color adjustments, transitions, shooting info, adding watermark, rotation, zoom & pan, as well as deflicker that helps reduce unstable brightness. Plus, you can export time-lapse videos to 4K, Full HD 1080p, H.264, and other formats.
Let's say you want an application to film yourself at work, at study, or even as a CCTV that safeguards the security of your home. SkyStudioPro can be the best choice for you. It's a piece of freeware that uses a webcam or external cameras to capture time-lapse videos with motion detection. Simply put, motion detection is a feature that increases the video frame rate for a short period of time when it detects an object or sound is being captured, so that you can see the object in slow motion clearly.
If you're looking for a tool to stitching images together, you can opt for the free MakeAVI tool. It offers a quick method to compile JPGs, PNG, BMP, as well as other formats into an AVI. What's more, you are allowed to crop images to needed dimensions. Unfortunately, MakeAVI functions well when handling less than a thousand images, but it could generate glitches in your time lapse video when working with over a thousand photos.
There are three factors when choosing a location to shoot time lapse videos: moving objects, a great night scene, and soft lights. Among the moving objects can be the clouds and traffic, as well as changes in shadow, because time-lapse videos will be no different from the regular videos if without variations. And strong lights are one of the elements to avoid in capturing day to night transitions, otherwise, it will be very troublesome in post-production.
This article has summarized 10 different time lapse video editing software with different prices, features, levels of use, as well as a few tips on how to shoot a time lapse video.
