Ok so I know I've already googled how to save videos in Blender, but a video tutorial from a sample slomo effect to saving the video in MP4 or what have you and then replaying said edited file to see it working. So I recorded a video on my phone and would like to add a slomo section to it, specifically the section where I want it to be in.has anyone that has used Blender or FFMPEG done slomo before? I've gone and read through this: and I was like ok, so tried it and I don't know if it worked or not.which comes to the next issue I have with it - how the hell do I save the edited video to MP4 or MKV or whatever container I wish? libx265 slow is even faster then libx264 veryslow for me.I'm.yeah.I just started with the video editing scene, rendering and encoding via handbrake for my fraps footages doesn't really count as video editing because I'm not adding all those cool effects you see on youtube videos!

This will save you a lot of space without quality loss. If you don't need compatibility to very old devices rather encode with libx265 or 2-pass libvpx-vp9. If you want a faster encode but a larger file set it to slow.

preset veryslow will use the best libx264 preset available to make the file as small as possible with H.264 (however needs more time to encode). Modern video encoders like AV1 will at most times set a keyframe every 10-20s based on scene detection.

Be aware that this increases the file size a lot, you should not use a keyframe every second, except for livestreaming. x264-params keyint=30:scenecut=0 will tell the x264 encoder to set a keyframe every 30s frames (here 1s) and to disable scene detection. Need to find your right setting there through testing) crf 25 will let the encoder decide on the bitrate for a medium quality (lower it for better quality / higher file size, increase it for worse quality / lower file size. vcodec libx264 will let ffmpeg encode in plain old H.264 r 30 befor input pictures will say ffmpeg to use 30 pictures per second Ffmpeg -r 30 -i %04d.jpg -vcodec libx264 -crf 25 -x264-params keyint=30:scenecut=0 -preset veryslow video.mp4

Blender what is ffmpeg
