Avidemux Forum

Hello I new here and am using this program to capture or try to capture "Stills" from videos/movies (All formats MPEG MP4 MOV etc) and click with mouse or key and save image clips. Can someone let me know how this is down by key stroke or with the mouse please ?

Thank you.

Bonsoir

Pouvez-vous m'indiquer comment activer ces options ?
Merci

PS je suis en Windows 11

Thanks. I have another question, as I often use avisinth scripts: among the VC++ versions, excluding the last 2 nightly, which one do you recommend using at the moment?

nightly 2024 12 14 ? or the old stable 2.8.1?

Thanks again.

1. Only the latest git master (currently the last working official build is r241212) and to some extent the last release (v2.8.1) are supported, with reported issues to be verified against with the latest development version.

2. By design, Avidemux displays videos always as they are coded, without any transformations (anamorphic corrections, rotation or mirroring) being applied.

3. Current Avidemux versions allow to specify anamorphic corrections (adaptation to non-square pixels) for MKV and MP4 muxers and rotation (for the MP4 muxer only) without re-encoding the video stream. Please mind that these transformations are hints for video players stored in the container, not in the video stream. However, the display in Avidemux itself will be always as the video is coded.

I have a video that is in vertical orientation.

The first image shows how it looks in VLC.

The second image shows how it looks in Avidemux (v2.7.6).

Why is it stretched horizontally in Avidemux, and how do I correct this?

Thank You.

SUCCESS!

I have done a few things.  I updated python to 3.13.2, which didn't seem to make a difference, unless I needed to reboot first but didn't before testing.  I see you posted about that and no surprise that it didn't make a difference.

Next I deleted the contents of the Avidemux installation folder.  I had thought that installing a new version over-top of the old was acceptable since it sees the old version, wants to install to the same folder it's in, and offers to keep the settings, but apparently not.

After clearing out the installation folder, reinstalled same version 2.8.2 r241212 again to that folder, standard install, and it has no problem with No Disk message, none of the other errors I posted about, ("so far" no errors at all), and it does use the script properly now to sequentially name and save PNG for all the frames instead of only the first 37 frames.

Thank you for the guidance!

Sorry that my replies were not more prompt.  I have this topic showing "Receive Emails and Alerts", and double checked that my profile has a valid gmail account listed, but I have not been receiving any email updates for this topic.  Gmail doesn't show them marked/blocked as spam either.

I should probably add that I use ZIP-packaged Avidemux builds for testing purposes on Windows (there are no other reasons for me to boot it in the first place), unless I specifically plan to test the installer. I extract it into an empty directory and run the graphical executable simply by clicking on it in the Windows Explorer window.

Usually, there are quite a few different builds in different locations, but they are never extracted over another build and also never run concurrently.

It doesn't rely on any (external) Python interpreter at all. The minimal subset of Python Avidemux uses is contained in the libADM_script_tinyPy.dll plugin.

While I was doing previous testing on Linux with a local build off the latest code (including bundled FFmpeg updated to 7.1.1), now I retried on Windows 11 24H2 with official r241212 nightly and a 30000/1001 (29.97) fps video – both working flawlessly.

Mixing different Avidemux builds in a same directory and also running multiple Avidemux instances simultaneously is a known recipe for a disaster, please rule out that any of above may be the case.

Once I have solved or at least understood the issue of decoding errors with H.264 streams in MPEG-TS containers, I'll request a regeneration of the official environment for cross-compiling Avidemux, which should ultimately produce a working fresh nightly build.
