3 streams in 1 output

Maybe there has changed something during the years. Is it possible in the meantime to define 3 sources and put it together to 1 output?

Re: crf with decimal value

I am sorry, but I don't have logs to compare. It was a question only, if decimal crf-values change the encoding speed dramatically. It takes as long as it takes and I do not have a lot UHD videos.

Re: crf with decimal value

Actually it are more than 2 questions. All around the crf optimization. Estimated time calculation seems to be very unexact. With crf=25 it was 8h, don't know how long it took really. With crf=25.25, it started with 10h, changed to 30 and after 6h now I have 50%. I thought there could be a differenc...

Re: crf with decimal value

Can it be, that crf=25.25 takes a lot longer than crf=25? Speed = slow From my understanding slow means, that the calculation is more exact and therefore the filesize is smaller. But what means crf. Movement is better with smaller values, but does it influence the image too, eg blue sky with clouds ...

crf with decimal value

I really hate it to be limited with 4 GiB but with FAT32 it is less surprise, if it works with some hardware. Crazy, that Android-phones (linux) do not support NTFS or exFAT, because there are linux -drivers available. Maybe it can be solved with 3rd party apps, but with some TVs you are limited aga...

Re: 10bit or 8bit encoding?

Are the recommended crf values für UHD HEVC 10bit. I remember there is crf=20 for dvd, lower values are most times useless. With HD-resolution I remember that crf-values are higher, when lower gets useless. So is there a crf-value with UHD HEVC 10bit, where lower gets useless. I am happy with crf=25...

Not me, the implementation of exFAT is buggy sometimes. Don't know if this is a linux problem or a problem of some mobile phones.

Re: 10bit or 8bit encoding?

The speed is not the problem, but maybe the size. While crf025 was ok with 8bit, it was below 4GiB, but it looks like with 10bit it will be over 5GiB, so FAT32 cannot be used anymore with a USB-stick. Don't know if it makes sense to use crt26 with 10bit instead of 8bit with crf 25.

General strategy for DVB-recordings

Description of problem or question: DVB-recordings can be very different DVB-S2 with AVC / X264 720p / 1080p DVB-T2 with AVC 720p / X264 with HEVC 1080p / X265 Probably the transmission is upscaled most times, so there seems to be no advantage to record 1080p instead of 720p. DVB-S2 with X264 has a...

Re: Bitrate X265 vs X264 comparable?

Thanks, so when I was happy with a bitrate of 1300-1500 with x264, a bitrate of 1000 with x265 should be compareable in quality? Most of my sources are DVB-recordings with an enigma-box in 720p. The quality of the sources is not the best and not comparable with BD.

I have a general question re X265 and X264. Should the bitrate be nearly the same, when I change the settings from X264 to X265 and do not change the rest of the settings? When I searched the net, I am unsure if using X265 should lead to a lower bitrate. I understand that X265 produces a smaller fil...
