Avidemux Forum

In the Crop filter check the "Hide Rubber Band".

I have been using Avidemux for several years on at least 6 systems (including setting it up for friends) and haven't seen this before.  I haven't found it in the index.

When I use filters, normally a screen comes up which shows the video, and various other pieces of information.  The video image used to always look the same as the main screen.

A day ago, the screen for the crop filter changed: it now has a red cross-hatch and red borders, which makes it much harder to see how to crop an image.  It appears to have changed only for the crop filter, the other filters still look fine.  I can't find any setting changes that could have caused this, and have not made any changes to my preferences.  The only changes to the system (Windows 10 22H2) are Microsoft defender security updates, and I don't think I even did that between the times the display was normal and when it showed red.  I did not install or remove any other programs during this time.

The only other thing that happened was that Avidmux crashed.  This appears to have been caused by a WMV video that was corrupted or improperly encoded.  I'm running 2.8.1

Does anyone know why this happened, and how I can remove it and get the 'normal' screen display back?

Thanks in advance.

Oh god...

>>> "Please provide a small example of this cr@p, or at least its Mediainfo."

What "mediainfo"? It's HEVC!! Self-explanatory! A compressed video file that decompresses/decodes on the fly during playback, which causes long pauses and hangs when manually jumping to random points in the movie, hence why HEVC sucks. Annoying as hell.

AVC does not do that, as it is not compressed, and the very reason why I want HEVC files converted to AVC.

Most times, a HEVC will convert to AVC without any undesired results that cannot be explained or corrected. I use the Constant Bitrate Single Pass @ 2500kbps (or higher, if necessary, which I do not find out til after 2 hours of converting time is wasted), in hopes that the output comes as close to a video bitrate of 2500kbps without going over (the occasional 2501 is acceptable) or less than 2495.

But every now and then, a HEVC file comes along that pulls this half-ass nonsense. HEVCs are smaller than AVC so they should always yield a bigger file size with a bitrate close to the value (2500+) that I entered, but it's slashing to much smaller instead.

I cannot see anything in the source file's details that would be a red flag. I use VLC and Mp3Tag ediotr to see this info (if it's available - another strike against HEVC is that all but the audio bitrate, run time, and filesize shows as blank in Mp3Tag editor - no aspect ratio dimensions, no video bitrate).

These problematic HEVCs appear no different from the other ones that convert easily ; same aspect ratio (1920x800-1080p), same audio codec (AAC), same audio bitrate (224kbps), same audio sample frequency (48kHz), same framerate (23.98 or 24 fps), and same container (mp4).

Since posting this topic, I suspect the only workaround is to take whatever LOW video bitrate output is yielded from an initial conversion, double it, and if the sum is more/less than 2500, then (respectively) subtract/add the difference to the target value preset of 2500, after DOUBLING it first (to 5000), and then modify accordingly until the desired outcome is achieved...? I have yet to test this theory for consistency and reliability, though... but based on the 2 recent experiences I had where this bizarre phenomenon occurred, it looks that way.

It's hard enough to obtain the desired 2500kbps (acceptable variable range of 2495-2501) - with no way to even get an estimated output BEFORE encoding so I am not re-encoding all day long trying to hit the target - without these random HEVCs adding to the hassle by pulling a "shrinkflation" stunt for no apparent reason.


>>> "What are these encoding options now?"

Whatever Avidemux 2·7·1 offers. I am honestly not sure what you are asking me here. I get the feeling even if knew and I told you, it would make no difference cos you'd be as clueless as I am as to the reason for this "HEVC half-ass" conversion issue.

I also doubt upgrading anything will even be possible (I assume that will be the default reply/suggestion from many ; the one-size-fits-all answer to everything, whether it makes practical sense or not - "juss UPGRADE, bruh!").

Sadly, I must be cautious with upgrading since I have an older system (XP 32bit) that I prefer, cos I have over a decade of work created on that platform, comprised of thousands of files that are dependent on unique-to-32bit programs that created and opens those files. If something won't run (is not supported) on XP 32bit, then it's useless to me, and I cannot afford newer computers, so even if I was open to an upgrade, finances say no.


>>> "You can use Avidemux in the portable mode, just download new version from https://avidemux.org/nightly/ to a new folder and  rename avidemux.exe to avidemux_portable.exe"

Portable shmortable. I have no idea what that means or anything about that. Sounds like bigger problems in a smaller filesize.

I see, the audio tracks configuration dialog exhibits a very minor issue of pre-selecting the first source track for every disabled output track on dialog construction, even if the number of active output tracks is less than the number of source tracks. The issue with that is that simply enabling a formely disabled output track will create a configuration (multiple use of the same source track) which Avidemux doesn't support yet, displaying a corresponding error message on accepting the dialog.

IMHO, a better approach would be to set combo box index to a source track not already in use and, as an enhancement, to add a "Restore default" button.

The lack of differentiation between source tracks (in dropdown menus) and output tracks (the "Track 1", "Track 2" etc. labels in the leftmost column of the dialog) may cause some confusion as well.

I have a video file with multiple audio tracks. When I try to go to Audio > Select Track and disable some of them to check which one is which, the next time I go back all the tracks just appear to be the same and track 1 is always enabled. If I try to disable it and enable track 2, when I check again just track 1 is enabled.

I second this request! I would love to have RIFE as an interpolation option. =:o}

Thanks dosdan2!!!

Use %%F and "%%~dpnF.mp4". The use of upper-case F is importand here so the command interpreter does not  confuse it with %%~f which is also a valid parameter extension.

Here's a test example, with 5 AVIs in the current root directory of "D:". How not to include the ".avi" in the full pathname and include ".mp4" instead:

dir /b *.avi

! x264.avi
60frames.avi
Dream World 038.avi
GA1.avi
Testfile_atempo.avi

Create TEST1.BAT

@echo off
for %%F in (*.avi) do echo "%%~dpnF.mp4"

Run TEST1.BAT

"D:\! x264.mp4"
"D:\60frames.mp4"
"D:\Dream World 038.mp4"
"D:\GA1.mp4"
"D:\Testfile_atempo.mp4"

Thank you @Geo_log - I'll have a look at this tomorrow 

I am trying to convert some classic 80's adult from avi to mp4. Through a google search I found a batch script that does work but the only issue I am having is the resulting file is named *****.avi. Is there a way for the script to remove the .avi from the file name so I don't need to manually rename each file? Here is the script I am using...

set avidemux="C:\Program Files\Avidemux 2.8 VC++ 64bits\avidemux.exe"

set outputformat=MP4

for %%f in (*.avi) do %avidemux% --output-format %outputformat% --load "%%f" --save "%%f.mp4" --quit

TIA
