It's a movie from a video game which I upscaled to real 4K with AI gigapixel.

I have two issues.

Firstly, despite stating "fixed 60 FPS" for some reason transcoding oscillates between 60.066 and 60.119 FPS.

Secondly, I try to transcode with "Libvpx_VP9 Lossless=1" option, but the filesize is almost 10 times the size of the movie, which is merely 80 MBs.

What am I doing wrong? Please help?

Any help at all with this please?

why vp9 ? use software h265 for best quality/size

Re: Huge file size when transcoding to 60fps?

what exactly do you expect when encoding with a lossless codec?

the file isn't that big to begin with, 70MB. How can it turn to 400? or 1GB+?

Re: Huge file size when transcoding to 60fps?

think of this: raw video data for 4k*3k*60 fps*15 secs video will be 4000*3000*1.5*60*15 = 16.4 GB

you probably should read something about losseless vs. lossy compression wink

The video is a lossy video - what do you recommend for conversion settings?

Use default settings. It is best choice for novice in encoding. Change them if you don't satisfied by results.

Apologies, default settings for what?

Google "HandBrake youtube settings" -> copy them in svp encoder -> try it -> repeat until u happy

Thats my setup
