Thank you, will download the complete log and look at it later, but regarding

A non-debug build takes approx. 500 MiB of disk space. No idea how much space still missing build deps will take on your system.

Quote from: JanMeki on November 12, 2026, 02:21:45 PMMy main concern is installing dependencies that conflict with something else.

Build dependencies are installed exclusively from already configured repositories of your Linux distribution (unless you try to create an appImage). Therefore there should not be any conflicts at this level unless your distribution has really screwed up.

None of this kind is involved when building (non-appImage) Avidemux.

Quote from: JanMeki on November 12, 2026, 02:21:45 PMIs everything being contained in that folder (avidemux2) or will anything install to my system directories as well?

All build dependencies go to the system. All compilation products go to the build directory. The build directory doesn't need to be the same as the source directory (avidemux2). I personally always perform an out-of-tree build to keep the source directory clean. Once compilation has succeeded, you obviously can manually copy the products to the install prefix in the system (default: /usr) if you haven't requested packaging from the bootstrap script, but you don't need to.

Here's the rest of the LOG. Seems like I didn't close avidemux before grabbing the log last time.

Quote from: eumagga0x2a on November 06, 2026, 09:35:40 PMThere is a script "createDebFromSourceUbuntu.bash" which automates (should automate) installation of dependencies, see README ("Debian / Ubuntu and variants"). Or do you mean that you are storage constrained, with little free space on the root filesystem?

No I should have enough space, if it doesn't take several GB's. My main concern is installing dependencies that conflict with something else. I've done that with pip before. Is everything being contained in that folder (avidemux2) or will anything install to my system directories as well?

Quote from: sark on November 09, 2026, 10:29:15 AMOne other question...Did you make it Keyframe only to satisfy your own needs, or was it a technical limitation. Just curious!

It was primarily based on my own needs rather than a known technical limitation. My workflow involves cutting H.264/H.265 MKV files in Copy mode without re-encoding, so I normally stick to keyframes to preserve the original video quality.

The main goal of these builds was to preserve and synchronize embedded subtitles after editing, something Avidemux doesn't currently handle automatically.

I developed and tested the solution around that workflow. I haven't explored whether the subtitle functionality could also support arbitrary-frame cuts with re-encoding, so I wouldn't necessarily call it a technical limitation.

Of course. I keep forgetting about the bots

Likely A without I.

Hello,
I configured the antivirus as described above.
Avidemux now opens very quickly.

Thank you.
With each update, the antivirus settings will need to be changed.

It's quite a hassle.

Thanks for the information.

I'll configure the antivirus, even though I'm using a portable version.

I'm very surprised that Windows 11 tests all the DLLs every time I use it, even though they were validated during download.
I'll let you know how it goes once I've done it.

**Steps To Reproduce**
1. Start Shotcut

If latest version refers to Avidemux, it does not confirm which version you are actually using, particularly when you state you start Shotcut, which I assume is a typo ? ... All a bit confusing !

**OS and Version (please complete the following information):**
 - Operating System: windows 64bit (Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz   3.19 GHz)
 - Software Version: latest version

**Describe the bug**
for Snapdragon 8 Gen 2 & 8 Gen3 based mobile phones， all 4K HEVC 60fps mp4 recorded by build-in Camera App，
does not play smoothly and stutters in this software. it seems a common case.

**Steps To Reproduce**
1. Start Shotcut
2. Load the mp4 file (you may record by any model of such mobile phones which equipped above SoCs)
3. Playback

**Expected behavior**
A smooth playback

**Screenshots**

Please see the recent topic "Question about updates" starting with https://avidemux.org/smif/index.php?msg=98741 (Windows Defender screwing up Avidemux and similar modular software is not new though).
