![]() ![]() * Use parameters that capture less data to encode from the start (like low framerates or resolutions). * Record directly from the frame buffer without compression and transcode later (which would only be available on high-end graphics cards with built-in hardware designed for this purpose, and even if the software existed to do this, it would result in massive files), or * Offload the recording to external hardware (video card) In other words, the solution you're looking for simply doesn't exist. Of course, it's only possible on a high-end graphics card that comes with the hardware to do this, which is already intensive to run, and is limited to 30 seconds at most. There are also tools like Shadowplay, which seemingly have no impact on performance, but that's because your GPU is constantly maintaining a copy of the frame buffer for the last 30 seconds (in other words, it's constantly recording, but by directly copying the frame that your GPU is passing to your monitor, which is more optimized than traditional screen recording). The best you can do is compromise on what footage you're capturing by lowering the frame rate or resolution so there's less data to work with in the first place. You can save in a lossless format and later transcode to a more compressed one, but you can't get a video with good quality and a small filesize without resource-intensive transcoding. There are codecs that can get the video stream very small, but they're intensive to run. There are codecs that don't do much transcoding, but these result in absolutely massive filesizes, because they don't discard any of that data. All you can do is take snapshot after snapshot of the desktop, and that data has to go somewhere. There's nothing (in regards to screen recording) that works the same way, because your screen isn't made up of predefined assets that can be scripted. If you took that "recording" outside of the game, it wouldn't work, because those assets were missing. ![]() Those demos are effectively the engine taking notes so it can recreate the sequence later. The file size is tiny because all of the large files - models, textures, sound effects, and the like - are already stored in the game files. It has a list of actors and props, and where they move to, but none of the information is stored visually. Instead of recording video, the game engine is saving something like a movie script. What you're describing is engine scripting. ![]() The ancient game Half-Life 1 has a feature where you can record demos, and the time span recorded is recreated in the game engine along with the audio from player's voice chat, the file size is tiny compared to an mp4/mkv/etc and hardly uses any system resources to record. There are codecs that have excellent compression, and you can even get a gif down to a remarkably small size these days, but they were still recorded as frames in a video and transcoded to their final iteration. ![]() That isn't the same as the "delayed encoding" you seem to be after. One of my professors used a document recorder that embedded a video file into a PDF, but the file size was always under 5 MB. Users can trim recordings, add captions, highlight important sections, draw on the screen to enhance the recorded content.In a decade of working with video, that's nothing I've come across. Movavi Screen Recorder goes beyond basic recording functionality by providing built-in editing and annotation tools. This is especially useful for automated and timed lecture recordings. Users can set specific start and stop times for recording sessions. To further enhance convenience, Movavi Screen Recorder offers a scheduler feature. This level of customization ensures that every aspect of the lecture is recorded precisely as needed. Users can choose to capture the entire screen, specific application windows, or even define a custom capture area. One of the key strengths of Movavi Screen Recorder lies in its flexible recording options. Its advanced screen capture options, flexible audio recording, video editing tools, and other impressive features empower both educators and students to create high-quality lecture recordings for effective learning experiences. Movavi Screen Recorder combines technical excellence with user-friendly features, making it an exceptional choice for recording online lectures. ![]()
