Some retain more of the original quality, e.g. ![]() Some codecs are faster than others, requiring less work from your CPU. There will always be some quality loss, but you can minimize it with your choice of video codec & the settings you use with or for that codec. Problem is that that data has to be encoded into a video stream that's then written to disk. The original picture you see is pretty much what's captured or recorded, regardless the software you use. some pictures were pixilated but the vast majority were not." the free x264 VFW codecs set at lower quality may provide a good balance, reducing the amount of data you have to write at 1080p, yet being fast enough to get the job done, albeit you'll have problems with a lower end CPU. Some are good for capturing, but a lot depends on the frame size of the video you're capturing, e.g. There are several codecs available, free & not, listed at videohelpcom. The ByteScout Screen Capturing app makes that part easier: "can use almost any video compression codec installed on your computer". And with video encoding you have to perform a sort of juggling act - the more video compression you have, the less data to write to disk, making that end of things easier, but more video compression generally requires more horsepower & is slower, which are both things you don't want. You want to be able to write to a hard drive fast - faster drives, RAID, & of course SSDs help. Similar to 10's gaming mode &/or apps for the same purpose, you want as little as possible going on besides displaying the source you want to capture, & the actual capturing itself. you need to write a lot of data to a hard drive in a continuous, *uninterrupted* stream. That said, the video capture basics haven't changed that much since the 90s. from a streaming source with DRM, as it takes some resources to play the video in the 1st place - you may need to turn off GPU assist playing the video so it's available for capturing & encoding for example, or the reverse. You can easily get into similar issues if you want to record playing video, e.g. With gaming oriented screen capture software the goal is more efficiency, so it doesn't use up too much of the horsepower you'd rather be using to play whatever game. With higher dollar apps you get features that make it easier/better to produce things like video tutorials &/or demos. ![]() From the ByteScout site it seems that their Screen Capturing app is always free for non-commercial use - *might* even be a bit of a demo to sell their screen capture SDK.īytescoutcom/products/enduser/screencapturing/screencapturing.html ![]()
