Avidemux Forum

Hi szlldm! I was referring to swapping the values.

OK i have lots of mkv files and and each need trimming once. Trimming is start to 44ish minutes.

Each MKV file are vfr and each has vfr timestamps. I then proceeded to cut each file and copy both audio and video to new mkv file. No encoding whatsoever. Some files worked and has vfr but some were converted to cfr without my say so. I want all files to be vfr as this is important.

Secondly, when converting the original timestamps is:

# timecode format v2
0.00
42.00
83.00
125.00
167.00
209.00
250.00
292.00
334.00
375.00 and so on.

After new mkv file was created the timestamps changed to:

# timecode format v2
111.00
153.00
194.00
236.00
278.00
320.00
361.00
403.00
445.00
486.00 and so on.

The above timestamp is wrong. It should be the same as the original.

For example if i were to trim a video from 0 to 60,000 frames out of 65,000 frames then the new timestamps would be 60,000 frames not 65,000 from the original. If i did this myself i would open timestamp into notepad++ and delete lines 60,002 to 65,001. I do not need to change anything else.

When i cut a video from 0 to 45:00.364, frames 0 of 65069, the original timestamp shown, using spreadsheet, arrived correctly at 45:00.323. The avidemux timestamp arrived incorrectly at 45:00.434. I do not know what methods you are using but would it be easier just export original timestamp, delete lines no longer needed, then import new timestamp, the same way as i did it by hand above.

So why does avidemux starts with 111.00, it causes audio/video sync to be off around 100 to 120 ms.

Edit:additional info.

I originally used the last official release and got 0 of 65064, 65064 frames, 5 frames short, video length 45:00.114. Not a big deal as they were black frames. I updated using the latest nightly built and got 0 of 65069, 65069 frames, video length 45:00.323, which is correct and perfectly cut. Obviously there has been some fixes so any chance of an official build so users can cut at the correct frame/time and get the right amount of frames.

Do you mean swapping the values, or swapping the position of the numeric inputs?

Hello! I don't know if this is a right place, but I'd to ask if adding a toggle swap  button for width and height of video size in Fit to Size filter would be possible? This small feature could be very handy. Something like that would be amazing:

Hello, when will be the new version of Avidemux ? Last version was in 2022.

1. Would it be possible to have a cmake project which includes the core, cli, plugins, etc.?
At the moment there are only two options (I'm on Linux):

• Calling cmake for each component manually, including the directory change, installing and so on.
• Using bootstrap.bash, which is really unnecessary complicated if something should be done differently. E.g., CMAKE_BUILD_PARALLEL_LEVEL is ignored because "make -j $(nproc)" is hardcoded, ccache cannot be easily activated via -DCMAKE_CXX_COMPILER_LAUNCHER and so on.

2. Avidemux cannot be build with another generator (-G / CMAKE_GENERATOR), except Make. Patching bootstrap.bash is trivial, but then this generator is wrongly used to built the included ffmpeg too.

Thank you!

Not necessarily. m4a as filename extension is just a human-readable hint that this particular MP4 container lacks a video track. The audio track(s) may use any compatible codec.

Quote from: Drakon66 on April 01, 2024, 08:33:31 PMWhy dont you make world better and just make avavilable this option by using ffmpeg.

1) You are and any other user is free to use any tool she or he deems best.
2) Avidemux doesn't use ffmpeg (the command-line tool), it uses some of the libraries which are developed by the FFmpeg project. In particular, it doesn't use libavformat for demuxing (and these parts of libavformat are not compiled into the library). Avidemux own demuxer plugins including the MP4 demuxer do not support files without video track.

There are much more urgent and rewarding tasks like adding support for chapters and for subtitle tracks than saving a very minor inconvenience to use ffmpeg to extract an AAC audio track from an MP4 container.

Bonjour,

Excusez-moi de répondre aussi tard, s'il vous plaît.

Merci.

1. First re-encode the video which needs rotation metadata to be displayed correctly with "rotate" and other necessary filters applied, using preferably a lossless codec (if you have plenty of storage space) or x264 with "Mezzanine" preset, then...

2. ...append all videos in appropriate order, then...

3. ...re-encode the whole using codec and encoder you need.
