Now, we know there are cases where carrying out enhancement and analysis on the originally recorded pixels is unfeasible in such cases, you are allowed to pick up the pixels in some other way, trying to minimize the quality loss. Failing in doing so may invalidate your whole work, especially since lawyers are getting tech-savvy, and they’ll question everything you did. When dealing with video for forensic purposes, preserving the best possible evidence is of paramount importance. You may try and reduce the amount of compression, but then find that your clip is actually larger in file size than the original! Recompression (known as transcoding) is therefore something you definitely want to avoid – unless you think changing the encoding algorithm is useful for the sake of better compatibility, as we discussed two weeks ago. However, in most cases, you’ll go through a recompression process: pixels will be decoded and re-encoded after the trim, thus leading to a quality loss. Trimming a video is something any video editing software lets you do easily. However, there are times when your video needs to travel or when it is appropriate to trim only the part of footage where the incident happens to avoid maintaining superfluous sensitive information. When everything is stored locally or accessible through a fast local area network, this could seem less than an issue. Depending on framerate, resolution, and compression, a single minute of video can eat up hundreds of MBs. Done!Ĭompactness is definitely not among the merits of digital video. Then, go to Export and choose Export Original Video as AVI. Use the “square brackets” buttons in Amped Replay‘s player bar to set the start and end of the range. But what if you need to send the file to a colleague? Is it possible to trim only the relevant part without lowering the quality? Keep reading to find out how Amped Replay lets you do this quickly! Dear friends, here we are with a new post of the “How do I do this” series! Have you ever found yourself dealing with a 1-hour long video where the only thing of interest happens for 5 seconds? As long as the file is sitting on a local drive, that’s usually not an issue.
