Avidemux Forum

Avidemux always displays video as coded. This is by design. Any transformation metadata like rotation or pixel aspect ratio are ignored. If you merge videos coded in different orientation, the result will be always broken. You absolutely must re-encode some of the videos to unify the orientation.

Hallo,

ich habe ein Video, bei dem Tonspur zum Film vorläuft. Nun möchte ich sie zum Film mit avidemux synchronisieren. Ich habe gelesen, dass man das über die Einstellung in audio über Filter wohl machen kann, aber das ist bei mir ausgegraut d.h. inaktiv. Wie kann ich die Tonspur zum Film synchronisieren?

The Media player first reads the "Rotate video" flag in the container (MP4 in this case). But Avidemux always ignores this flag because it is an editor, not a pleer.

No, if you save your video with flag = "Do not rotate" as in the attached image, Avidemux will open it non-rotated.

 "Geo_Log" and it work but I dont want to render/re-encode my video just work on my copies.

 I use option in configure. The output is set correct but when i open it again by avimedux its again rotated. Why it is so much complicated

Please provide a sample preferably via WeTransfer (no email address required despite the site trying to suggest otherwise), Mega, Dropbox or Google Drive.

It's just an information about that the decoding can't keep up during playing the video in Avidemux, so you can experience lag between video and audio.
It does not affect editing.

No need to worry, this isn't even a "Warning", it's really just an informational message about Avidemux video decoding performance.

Hi
I've tried a few different nightly releases of Avidemux, currently running 2.8.2 (240316) (Win_x64.

When I try to play an MP4 clip in Avidemux I keep seeing a Warning message in the bottom left of the Avidemux window You cannot view this attachment.. As the clip plays in Avidemux the milliseconds ramp up.

Converting and editing the clip, removing sections of uninteresting portions of the clip seems to work okay. But I'm worried I'll forget to check one day and the proverbial will hit the fan. It may just be a setting I've got wrong. The playback of the clip in Avidemux runs quite choppy so I wonder if you could suggest what may be happening. I'd rather not go back to some distinctly earlier version if I can avoid it.

Thanx in advance for any suggestions.

 

Hi there,

I have several MOV videos captured by iPhone 14 Pro Max, SW: 17.3.1 which have AVC video and AAC LC audio.
When I open such a video in Avidemux 2.8.2, it says: No Audio in the File\Information field but when I open the same video in Avidemux 2.8.1.22260, the audio is correctly recognised.

=====================================================
Audio (1 active track)
=====================================================
Codec:            AAC
Channels:         Stereo
Bitrate:         23356 Bps / 186 kbps
Frequency:         44100 Hz
Total Duration:         00:00:09.404

Any clues what's wrong?
File information of the same video generate by the Avidemux 2.8.1 and 2.8.2 as well as MediaInfo are attached.

Thanks.

Hi! Instead of the Margin Top and Margin Bottom options (btw, both existing Margin options only take 2-digit values and are worthless if you want to use them to position text in a 16:9 aspect ratio), I think it would be better to use one field that can position subtitles by given pixels (or percentage) from the top. Why? Currently, if you add black borders to a video and set the video to 1920px resolution, the added subtitles will be mismatched and will not be able to be adjusted accordingly.
