What programs can reduce movie clips without reencoding?
Are there any programs that can trim movie clips without reencoding the videos and allow for higher volume settings without reprocessing the files, such as Mp3Gan? If minor adjustments are needed, would that require reencoding the entire movie?
Free Video Editor is described as a lossless, straightforward editor.

VidCutter x64 is another option; it's unclear where to locate it.
I'm uncertain if you can change the volume with them.
BSFAG is said to be able to adjust volumes, though I believe it might need re-encoding.

Welcome to BS Programs website! This is my collection of computer programs or applications I created for fun and found useful. They also serve as a space to improve my programming abilities. I've shared them here for everyone's benefit. 👍 Please ensure you're using the most recent versions.
website requires mp3gain and FFMPEG.
I haven't tried any of the methods mentioned.
You can import many video files into Audacity and then modify the audio volume. It's not clear if this meets your needs.
Video encoders function as compressors, using compression by identifying patterns within data segments that can be represented concisely; the more extensive the segment, the higher the efficiency, with a single continuous video achieving optimal results. To reduce size without reencoding, the video must be divided into distinct chunks, and cuts must be made exclusively on these segments, not elsewhere. The frames eligible for cutting are called i-frames.
With Audacity one would need to save the new audio track, then employ tools like mkvtoolnix to merge it with the existing video.
You can utilize FFMPEG for this purpose.
Example usage:
Code:
ffmpeg -ss 30 -i movie1.wmv -c copy -t 10 movie2.wmv

Volume adjustment example:
Code:
ffmpeg -i movie1.mp4 -af volume=7 -vcodec copy movie2.mp4

Additional settings are often necessary to prevent reencoding. FFMPEG is a well-established tool with a strong community, making it straightforward to locate tutorials and practical instances.
FFMPEG supports this task, though it needs matching encodings across source files. Generate a text file named vidlist.txt with the clip names you wish to merge:
Code:
file '/path/to/clip1.mp4'
file '/path/to/clip2.mp4'
file '/path/to/clip3.mp4'
Then run the command:
Code:
ffmpeg -f concat -safe 0 -i vidlist.txt -c copy output.mp4

I believe Free Video Joiner can handle basic combining without re-encoding, though combining different formats might be tricky. I've tried it, but not very often. More sophisticated tools like Avidemux offer greater flexibility, but they're far more complicated and have a steeper learning curve. Free Video Joiner features a very straightforward interface.
