Unix-Like (Linux/Bsd/...) / Why is the crash dialog tiny AND fixed-size?
« Last post by FeRD_NYC on November 11, 2018, 10:27:05 AM »
I have two bugs to report, so I'll start with the easiest one first. While using avidemux3_qt5 on Fedora 29 running under Gnome Shell, from the rpmfusion package avidemux-qt-2.7.1-5.fc29.x86_64, I encountered a crash. These things happen.

But the crash was reported to me in this dialog:



...which cannot be resized. That's just... kind of cruel. Please make the window resizable. And, ideally, bigger to start with.

MacOSX / Re: 2.7.1 crashes when I try to load an MKV file

Glad to hear that, thanks. Meanwhile, the playback without downmixing has been fixed in code, will work in future nightlies.

Please note that on a MacBook*, 5.1 audio doesn't get automatically downmixed by the sound system, so with local downmixing in Avidemux disabled in preferences, you would hear really only the front left and the front right channels out of the internal speakers.

No, the results won't be different in any kind for mkv. Yadif and the VDPAU-based deinterlacer with recent NVIDIA graphics cards are hugely superior to any other method offered by Avidemux. Please note that no deinterlacer can rescue a video which was resized prior to being deinterlaced.

I had previously extracted a 50 second long clip from one of my DV files into a .mov container (mpeg4) and Avidemux accepted that just fine.

DV is not possible in mp4, you must have had re-encoded the video with a different codec.

Thank you for the helpful reply (insert smiley here).

What attracts me to Avidemux is the ability to rapidly preview the filters (unlike ffmpeg). I had previously extracted a 50 second long clip from one of my DV files into a .mov container (mpeg4) and Avidemux accepted that just fine. There are so many deinterlace filters and, although yadif2x is highly recommended by some people, I found that 'linear interpolate' in Libavdec Deinterlacers' gave the best visual results to me. So many filters - but in many cases, so little results. I now wonder if the results will be different for an mkv container.

Main version 2.6 / Re: Any chance to keep subtitles in TS files?
« Last post by eumagga0x2a on November 09, 2018, 04:10:28 PM »
Whoever is interested in subtitle stream support getting added to all the required components (core libs, MpegTS demuxer, editor, at least the MpegTS and preferably MKV muxers), should contribute code or hire a professional developer to work on the project.

I read this a bit old topic and I'd like to know if anyone is aware of any change in the future version of ADM.
Considered how many devices, especially the ones linux-based, use the .ts format with embedded subs, it would be great to have them preserved, as many other user have said ;)

As the error message states, Avidemux lacks a demuxer for this format. You could resort to command line ffmpeg to remux the file in copy mode to MKV:

Code: [Select]
ffmpeg -i infile.dv -c copy outfile.mkv
Avidemux should be able to load the resulting MKV. Obviously, you can use ffmpeg also to deinterlace the video: https://ffmpeg.org/ffmpeg-filters.html#yadif-1

Unix-Like (Linux/Bsd/...) / Avidemux Cannot find a demuxer for filename.dv
« Last post by kenj69 on November 09, 2018, 05:21:49 AM »
I recently used an ADS Pyro Link A/D converter to convert 17 Hi8 analog home video tapes into raw dv files. Kdenlive and Shotcut accept these NTSC standard DV files without complaint but Avidemux puts up an error message window saying, "Cannot find a demuxer for filename.dv" and then, "Could not open the file."
I would dearly love to deinterlace these files using Avidemux but it won't accept them until I convert to another format. Can someone please explain the problem?

Windows / Re: up down arrow keys fast forward/rewind setting
« Last post by eumagga0x2a on November 08, 2018, 08:35:51 PM »
Using Up/Down arrow keys or dragging the navigation slider seeks to keyframes, that's why it is fast. The seek granularity is determined by the way the currently loaded video has been encoded, short groups of pictures (GOPs) = small jumps, long GOPs (better compression) = big jumps.

To seek time-based instead of keyframe-based, use Shift+Left/Right (1s steps), Ctrl+Left/Right (2s steps) or Ctrl+Shift+Left/Right (4s steps) shortcuts. All of them are comparably slow due to the nature of video compression, especially when seeking backward.

Windows / up down arrow keys fast forward/rewind setting
« Last post by jaaney on November 08, 2018, 08:06:23 PM »
Trying to edit/skip a video using the up/down arrow keys on the keyboard so i can quickly skip through the video however it skips like 10 seconds at a time, I would like to skip 5 seconds or less using the up or down arrow keys quickly not left or right arrow keys cause that's forward/rewinds it too slowly, is that possible to change this setting somewhere, if so please give me the exact steps.
