Hi ProWo,

I haven't used this little gem for a little while now, so I have a question...I notice that in "Video Conversion" there is a "Colorspace" option...does this allow a HDR to SDR conversion ??

I have since downloaded the latest beta build, and I am wondering if you could add an nVidia Decoder & Encoder options for those of us that have suitable nVidia GPU's.

Belong the colorspace option: No, it isnt for HDR to SDR conversion, but for conversions between HD (g.e. 1280x720) and SD (g.e. 720x480) resolutions.
HDR to SDR conversion is be done by conversion of HDR stream without the check of HDR encoding.

What about Nvenc i'll see what can be done.

Hi ProWo,

Not sure why there are 2 identical posts (might as well delete one).

OK, so thanks for replying, and I did a little test yesterday with HDR to SDR, or your BT 709 option...

I loaded a HDR HEVC movie (Batman), and basically only chose the BT 709 option, and let it go....other than being extremely slow (even with my 12 core CPU), I only let it run for about 10 minutes, and played what it had processed, and it looked pretty good, I checked it with Mediainfo, and it definitely wasn't HDR anymore

If that conversion could be done using nVidia GPU's, that might speed up the process.

Anyway, that's my feedback.

Regards

Hi, Pauly Dunne
Sorry, but for further there will be no support for hardware acceleration.
Too many limitations, many options and filters can't be used, output quality can suffer.
My motto: Better slow, but good quality.

Hi ProWo,

Well, that's sad, but if you don't think it's the way to go, then that's it.

Thankyou for at least looking into for me.

But having said that, since posted my request, I went looking, and found another FFMPEG based app called Axiom....it seems to do a lot.

Have been testing it, seems OK, but like every new thing one tries, requires a steep learning curve.

Cheers

Does this REALLY convert audio to E-AC3 7.1 ??

I tried a couple of times, and just got an error, and that was it.

I extracted the .dts and then re loaded that as the source file, and tried the conversion, but I couldn't understand how to then process it

Conversion to eac3 7.1 cant be done atm.
This is a limitation by ffmpeg itself.

Just discovered this app, thanks much, ProWo!

Would it be possible to introduce a file integrity check/verification of some sort?

I see FFMPEG has a "error" and "debug" flag, so perhaps it wouldn't be too difficult to implement?

I don't know if there's a newer/easier FFMPEG feature, but I found these postings from 2015 describing usage of some of the flag options:
https://superuser.com/questions/5736...mpeg-exe-in-wi
https://superuser.com/questions/1002...e-avi-mpeg-mp4

Thanks!

@ aigo
The error messages from FFmpeg don't really help.
At most, they serve as information; if a video stream is really defective, then in the vast majority of cases it cannot be used anyway.
Small correction algorithms that FFmpeg provides are already built into clever FFmpeg-GUI, in audio and video conversion, cutting, joining or multiplexing.
