Quote from: Mew12 on July 31, 2026, 10:14:00 AMRegardless of the settings, it removes some black areas from the image.
So deep blacks are gone.

I would interpret the screenshots as the "original" being a result of the renderer ("DXVA2"?) incorrectly interpreting fullrange (0 - 255) input as limited (16 - 235) range one thus losing all the details. The second screenshot looks correct to me.

Thanks for the reply.
I know what you mean, but it's the other way around—exactly as I described it.
When i use VirtualDub for example and it uses Limited, it looks correct like the original with Avidemux as i posted.
And if i use Full Range, deep blacks are also gone and it looks like the Wavelet sharpener output.

Quote from: Rainman74 on June 16, 2026, 10:50:05 AM@eumagga0x2a Why do the current nightly builds no longer support NVENC? This unfortunately renders them unusable for me.

Should be fixed in the 260729 build.

Thank you very much!

I think it's very important Avidemux should give a warn when sees an unsupported stream in MKV (like soft subtitles), that will be removed on conversion/copy of audio/video streams.
I'm quite advanced user but converted many video before realizing it removed all of that. Fortunately of some I kept the original, extracted subtitles and re-added, but some I lost the subs.
I Imagine many users fall on this, and it is a subtle dataloss bug/rfe.

Currently 2.8.2 nightly 260516 on Debian 13

Hi,

Do you intent to update the included ffmpeg to a newer version (latest is 9.0.1) ?

several CVE issues have been fixed since 7.0.2

Hello,

Perhaps by using the newer MinGW64 versions that use Qt6...
But that's completely unverifiable...
It seems that adding features to AviDemux is more important than updating a version that's already running.

No, there haven't been any changes to bundled FFmpeg libs.

Cross-compiled builds should show the last git commit hash they have been generated from in "Help" --> "About Avidemux" dialog. Search for that commit in the repository then.

The course of action regarding FFmpeg will be evaluated as soon as possible. Whoever is concerned about security but needs to be able to sleep at night should never read Apple Clang warnings when compiling FFmpeg
