Suggestions for improvements
« on: October 20, 2019, 09:12:30 PM »
Here are things that would improve my experience of Avidemux, which is rather good to begin with:

Be able to test run the set time window from start marker to end marker exactly.

Have MPEG-4 as the Output Format default (who uses MKV anymore?), or make it possible to configure the default setting.

Force the end marker after start marker if it currently is before the start marker. Right now it silently doesn't set the start marker if the end marker is before.

Also, maybe a "frame chase" issue: Sometimes it won't start at the right point, but it always ends at the right point.

Cheers from Smurph Village.

Do you have copy mode or re-encoding in mind? What purpose should this serve? For copy, please keep "sanitize timestamps" option disabled. It should be replaced with something more sensible later, which might include some sort of an internal "test run" to avoid introducing jitter.

MKV support more codecs than MP4 and will probably remain the default for this reason.

This is possible for years (in the "Edit" menu with Ctrl+Alt+D as keyboard shortcut on Linux and Windows).

??? Markers are automatically swapped to ensure B >= A for even much longer. Do you refer to a current supported version of Avidemux?

In copy mode, the start time is always adjusted to the previous keyframe if it is not already at a keyframe. Anything else makes simply no sense as the first GOP won't be decodable. When re-encoding, the start point can be set to any type of frame.
