A few weeks on and I have some tweaks to the script, which now includes 'max-cll' variables. A tweak to the readhdrvalues function, which strips out anything after the / in the ffprobe output... function readhdrvalues () { echo "Reading HDR values..." echo $1 ffprobe -loglevel quiet -read_intervals...

Is there any word on this? Typical use case, a DVD with 7 episodes... there are 8 tracks on the disc - 1 track with all of the episodes together and then the 7 individual episodes. So, my usual command line will save 8 titles, wearing the precious drive out longer... $ makemkvcon mkv disc:0 all /tmp...

Does anyone know which TITLE is the correct one? I've just listed the 4 contenders! File 00200.mpls was added as title #0 File 00101.mpls was added as title #1 File 00100.mpls was added as title #4 File 00300.mpls was added as title #15 TINFO:0,30,0,"Harry Potter and the Deathly Hallows Part 2 - 38 ...

Hi all, This seems like the best thread to ask, what would be the command line for ffmpeg to keep the 4k video untouched, take the first of multiple audio files but convert that hopefully lossless from dts to ac3 or any other lossless codec (any advice on a codec appreciated) Thabks Wow, your ears ...

Sorry if this sounds obvious

But if I run that handy script, does it compress a 4k hdr mkv file? With acceptable quality?

...and don't forget that 8GB size includes an extra audio track for MY tastes, so if you only wanted 1 audio track then that size would come down!

Yes.

A typical UHD REMUX goes down from 40GB to about 8GB.

A few weeks on and I have some tweaks to the script, which now includes 'max-cll' variables. I will create a github at some point, but for now, here are the important parts... # set main variables TITLE="Movie Name (YEAR)" INPUT="/home/user/${TITLE} UHD.mkv" OUTPUT="/home/user/${TITLE} 4K ffmpeg 2 A...

Hope you and your family or staying safe.

Yes, we're alright for now... hope you are too.

My UHD Drive is still going strong thanks!



Kind regards,

I was hoping to extract these figures and put them straight into ffmpeg. OK, here is a quick BASH script to do what you want, just outputting 1 of the variables as a test... ffprobe -loglevel quiet -read_intervals "%+#2" -show_entries side_data "input.mkv" | grep -A 10 'side_data_type=Mastering dis...

Oh, no problem.

I can help with that tomorrow.

e.g. using your example above, the 'master-display' setting would be... master-display='G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(1,10000000)' I ran that ffmpeg command to analyse my MKV of a UHD... $ ffprobe -read_intervals "%+#2" -show_frames -show_entries side_data "input.mkv" [SI...

It outputs the values required for HDR: red_x=34000/50000 red_y=16000/50000 green_x=13250/50000 green_y=34500/50000 blue_x=7500/50000 blue_y=3000/50000 white_point_x=15635/50000 white_point_y=16450/50000 min_luminance=1/10000 max_luminance=10000000/10000 That I haven't been able to extract using me...

Found this in another website which may be of some help: ffprobe -read_intervals "%+#2" -show_frames -show_entries side_data "video.mkv" Also is it possible to add auto crop to your script? Interesting, what does that do? Auto crop... yes. Here is a link to my Wiki which has a page about ffmpeg and...
