I wonder, I'm trying to "refurbish" some old videos to 4k and 60fps. What's the good way to do this, upscale first then transcode? or the other way round?
I see. Thank you.
No temporary files in the OS drive?
So, I have SVP installed on a different drive - yet, during and after today's huge transcoding effort, around 15 of my GBs on my C: drive have been occupied. The temporary file has already been deleted. Where are the leftovers so that I may delete them directly?
Bluray players are very sensitive to profile level and advanced settings used in H.265.
I see you are using x265 coder and profile Main@L8.5@Main. Perhaps it is not good for your Bluray player. Try another more standard settings when encode.Variable framerate can be a result of combining two videos with different framerate into one video.
How your questions are connected to SVP? Are you using SVPcode?
I bought SVP and am trying to transcode video collection to 60fps for playback on TV.
I'm not sure how to change the Main@L8.5@Main setting. Could you please help?
So, I'm a bit confused by this Mediainfo:

How come frame rate is variable rather than fixed?
And for some reason my Blu ray player (specs here) cannot play the output videos. I wonder what I'm doing wrong. Could you please help?
Thanks. I wonder if preset veryslow will change something!
The one specified here: https://x265.readthedocs.io/en/default/lossless.html
The settings you use for waching are the ones used for transcoding. They appear to be slightly bugged this release tho.
I believe it's actually 60 fps, but mpv/ffmpeg always (?) encodes as "variable frame rate" so "60.119" is an estimated value.
If you know ffmpeg option to make the output "constant frame rate" - let us know
It's not this one, is it: https://trac.ffmpeg.org/wiki/ChangingFrameRate

This is what the log returns.
I did x4 ratio but it still led to the same mistake.
As per title: transcoding 5K video which is exactly at 15 fps doesn't lead to exact 60FPS.
Thanks!

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?
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
The video is a lossy video - what do you recommend for conversion settings?
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+?
why vp9 ? use software h265 for best quality/size
doesn't work with Youtube otherwise!
Any help at all with this?
Any help at all with this please?
Well I suppose I can try. Would appreciate if you'd also check, it is part of Libvpx functions and should be recognised by your programme.
"b:v" is a video bitrate
add "b=2M" to ovcopts
thank you but according to the link I posted the full command is supposed to be "-b:v 0"
Would "b=0" work?
So, I'm trying to convert this video to 60 fps

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?
I'm trying to transcode a Libvpx VP9 video - trying to avoid most options because file size is really huge.
However, since we can't use 2-pass transcoding with SVP, I'm trying to find a compromise solution, as specified here: https://trac.ffmpeg.org/wiki/Encode/VP9
However, the "b:v" option isn't listed as supported in the drop-down menu. Could it please be done for the next release?
