Avidemux Forum

подтверждаю, что это полностью нестандартный способ создания видео
  с вставкой в него слайдшоу, которое создано с другим количеством кадров в секунду
но это очень быстрый способ, тем более, что youtube со своей стороны всё исправляет кодированием в vp9

ffmpeg строка ненужна, в связи с тем, что суть не в слайдшоу, необходимо соединить в Avidemux два видео, то есть 1fps.mkv вставьте в середину видео 50fps.mkv и сохраните используя метод "copy"

• конечно вместо "copy" можно закодировать

• но на скорости меньше 200fps
• и, это непоможет
• а vlc несможет воспроизвести кадры из такого видео в части с 1 fps, поэтому необходимо задействовать фильтр "преобразования кадровой частоты", но тогда баг с зависоном укоренится

если одно из видео несодержит звуковую дорожку, то звуковые дорожки нужно, либо выключить, либо неиспользовать метод "copy" для звука

Есть ли скрипт обнаружения тишины для Avidemux с целью удаления фрагментов, в которых она присутствует?

• если нет скрипта, то нужны звуковые дорожки, чтоб видеть фрагменты, в которых тишина присутствует
• и ещё нужно редактировать фрагменты, иногда очень надо; хотя бы просто панель с списком фрагментов, который кстати создаётся при сохранении скрипта проекта, но редактировать его можно, только в редакторе кода, но непонятно, почему нельзя редактировать фрагменты в Avidemux, например, иногда нужно вернуть удалённую часть фрагмента, а возможность такая отсутствует
• и ещё нужно иногда приближать/отдалять таймлайн с фрагментами, а возможность такая отсутствует тоже

I confirm that this is a completely non-standard way of creating videos

• with inserting a slideshow created with a different number of frames per second

but this is a very fast way, especially since youtube, for its part, corrects everything by encoding in vp9

The ffmpeg line is unnecessary, due to the fact that the point is not in the slideshow, you need to combine two videos in Avidemux, that is 1fps.mkv insert into the middle of the 50fps.mkv and save using the "copy" method

• Of course, instead of "copy" you can encode

• but at speeds less than 200fps
• and that won't help
• and vlc will not be able to play frames from such a video in the 1 fps part, so it is necessary to use the "frame rate conversion" filter, but then the hang-up bug will take root

if one of the videos does not contain an audio track, then the audio tracks should either be turned off or not use the "copy" method for audio

Is there a script for detecting silence for Avidemux in order to remove fragments in which it is present?

• if there is no script, then you need audio tracks to see fragments in which silence is present
• and you still need to edit fragments, sometimes it's very necessary; at least just a panel with a list of fragments, which, by the way, is created when you save the project script, but you can edit it only in the code editor, but it's not clear why you can't edit fragments in Avidemux, for example, sometimes you need to return a deleted part of a fragment, but there is no such option
• and sometimes you need to zoom in/out of the timeline with fragments, but there is no such option either

Thank you for the sample. I confirm that Avidemux exhibits a number of issues with it (the sample violates a whole lot of assumptions), especially the real frame duration being that much longer than the default frame duration specified by the codec as well as at the container level breaks navigation (you cannot go to the previous frame at the boundary between the "slideshow" and the continuation of normal video).

Yes, please provide the ffmpeg command line for the ease of future testing.

Quote from: scscorpin on May 24, 2024, 04:45:54 PMHow can I switch hardware acceleration to Direct3D11 or NVIDIA CUVID in Avidemux?

The former: you'd need to implement it yourself, Avidemux still uses d3d9. The latter: please use a current nightly, the ancient 2.8.0 release is entirely unsupported.

However, the playback issue is entirely unrelated to hw accel, it is a bug in the GUIPlayback::run() function. Other issues affect filtering.

Brilliant!

But how did it get changed? "Local playback downmixing" was set on 'stereo headphones', and "audio device" was set on 'dummy'! No wonder I couldn't hear anything!

 

Я определил баг при использовании vlc, там используется Direct3D11, поэтому там всё нормально воспроизводится, то есть баг в DXVA2

DXVA2 смещает кадровую длительность на один кадр

в mpc как и в Avidemux используется DXVA2, но когда в LAV использую NVIDIA CUVID, то в mpc всё нормально

а как в Avidemux переключить аппаратное ускорение на Direct3D11 или NVIDIA CUVID?

I identified a bug when using vlc, it uses Direct3D11, so everything plays fine there, that is, a bug in DXVA2

DXVA2 shifts frame duration by one frame

in mpc, like in Avidemux, DXVA2 is used, but when I use NVIDIA CUVID in LAV, then everything is fine in mpc

How can I switch hardware acceleration to Direct3D11 or NVIDIA CUVID in Avidemux?

Check Preferences/Audio/AudioDevice. It should be PulseAudio.
Also check system settings (Sound/Applications).

Hello,

I'm a long-time user of Avidemux (current ver 2.8.1 & running on Linux Mint Cinnamon) for editing my videos. While I use it a lot, I'm far from a power user, for the most part using default settings except I change the saving format to MP4.

Yesterday everything was fine. Today, it won't play audio, even tho the videos I've brought in to edit are all fine. I can "see" the audio bouncing around in the bottom right corner graph, and my Audio Tracks Config setting says track 1 is enabled.

Any ideas on how to fix the issue? Googling hasn't been helpful.

Reencoding is a heavy computational load, if done on the CPU, it could warm up a lot. Cleaning the heatsink and the fan might help a bit (i have assumed you have an older laptop bc of win7).
Reducing size naturally reduce sharpness (due to loss of details). Anyway make sure that all post processing options are disabled in the preferences.

Hi, I'm using win7 and the latest version of avidemux. When I try to reduce the size (i.e. the "weight") of a movie my laptop heats up very much - 85-90 C°! and the file loses a lot of sharpness.... how can I improve?

Old thread, but still, "issue" or "feature request" remains strong, well at least on my behalf. Running latest Avidemux, appended clips are still put behind (at the end) of current video, and this cannot be changed by putting out cursor at a certain point or I-frame. I can, however, accomplish putting clips in the middle by (after first having it appended to the end) CTRL+X:ing / CTRL+V:ing (respectively) the appended part. This way I can save clips untouched (not re-encoded) á la stream copy. But it would be one step less if there was a way to just append the clip to my located cursor point. Can we totally forget about (stop wishing for) this feature to appear in upcoming versions, or is there hope?

Can you just answer that question

The "jin_00552_1_edit.mkv" video is totally erroneous and cannot be repaired with even with the help of the famous VideoReDo tool.
