I personally use ffmpeg to convert mp4s to the x265 codec, seems to be much more efficient than the x264 virtually all videos come in but may not play properly on as many devices (iirc if you're on Windows you may need to install an add on in the store).Does anyone know any software to compress videos OR reduce the size while maintaining the original Sharpness - currently I use Format Factory to reduce the size but reduce the Video Sharpness.
So does anyone know any good video compression software?, because I am storing 6tb~6tb500 videos of 2D & 3D HenT, Ugoira live2d, CAV, JAV, Porn, contains a lot of videos but don't take advantage of those videos to make money. The reason why it contains so many videos is because you're afraid that if you don't download it, you'll lose that video and feel regretful.
If you're familiar with ffmpeg, here's a simple one line command to convert mp4s into x265 mp4s. Just paste this into a word file and replace the .txt at the end with .bat.
for %%f in (*.mp4) do ffmpeg -i %%f -shortest -vcodec libx265 -crf 25 "%%fx265.mp4"
Stick the .bat file in the same folder as a bunch of videos you want to convert, make sure to rename them so they don't contain spaces or special characters and let it run. The resulting videos will all be renamed with an extra x265.mp4 at the end, ie if the input is named video.mp4 the resulting output will be named video.mp4x264.mp4.
The number after crf (constant rate factor) has to be between 0-51 and denotes quality (higher number = lower average bitrate/quality/file size and lower number = higher average bitrate/quality/file size) and can be changed depending on your needs. From personal experience for animated content, I've found that crf 25 is a nice middle ground that may slightly reduce video quality on larger monitors for a massive reduction in file size. I recommend trying out different values to see what works for you. If you're fine with a somewhat larger file, I notice no difference in quality between original and crf 22 on my 1080p monitor though your mileage may vary. If you need your file to be even smaller, you can try crf 28 though that results in a noticeably impact on quality for a lot of videos. If the original video's quality is poor, the higher you can set the crf without seeing a reduction in quality.
