Is it possible to preview the filtered video part?

[arnoldpredator]

If I have a large video and I set points A and B to a video of just 10 seconds, Is there any form to preview what I will get?

I thought that if I click on "play filtered" I would get what I want but nothing happens, when I click on play I just see the whole video not the part that I selected.

I can only see the result of my cut after saving the video, Is that correct?

Could you please elaborate? Are you going to save in copy mode? Reencode? Reencode with filters? Reencode with partialized filters? Do you expect the preview to stop at B? (No, it won't, unless you delete everything past marker B.)

I thought that if I click on "play filtered" I would get what I want but nothing happens,

I agree that the wording has become confusing when the original checkbox turned into a sort of a button when it was moved to the invitingly empty toolbar (the checkbox exists in the "Video" menu, but not in the toolbar). The problem is that every modification of a translatable string requires a dozen of translations to be updated

"Play filtered" means "Apply active filters on the fly when playing video". It can be enabled only if filters can be enabled, which requires a different video codec than "copy".

when I click on play I just see the whole video not the part that I selected.

It plays from the current position and stops at the end of the video, i.e. you must navigate to marker A first (press the button next to "A:" in the selection widget). If "play filtered" is enabled, it will apply video filters and show the result. In contrast to the normal playback, it will return to the starting position when stopped.

I don't save in copy mode, I need to choose mpeg4 asp(xvid4) and audio (aac) so I can save a small video, in copy mode it doesn't work because the keyframes do not coincide normally with the points I want as starting and ending points.

Yes, I expect the preview to start at the point A and end at the point B so I can see what I will get after saving.

Ok, thanks for the explanation of play filtered.

What is the button or the shortcut to "navigate to marker A"? And the same for B?

That could do the job to check at least if the point A is correct.

I see these buttons:

-go to next frame
-go to next keyframe
-search next black frame
-go to last frame (end)  (I tried this but it went to the last frame of the whole video, not to point B)
-forward 1 minute

I know it is possile to go forward 1 second, 2 seconds etc but I don't find how to go to A or B.

Do you use a recent nightly? The buttons are labelled with the time of A and B, directly above the "Selection:" label in the selection widget.

The default shortcuts are PgUp for A and PgDown for B. The alternative shortcuts are "A" for A and "B" for B.

The default shortcuts are PgUp for A and PgDown for B. The alternative shortcuts are "A" for A and "B" for B.

To get the alternate hotkeys, "A" & "B", working you first need to use Edit | Preferences | User Interface | tick "Enable Alternative Keyboard Shortcuts" | OK.

BTW, what are all the other alternative shortcuts that this option enables?

Thanks folks!

I saw the timing but I didn't know I could click on them and the video went to those two points :facepalm:, sorry. Very useful.

This software is so good it has all the features I needed.

Thanks to all the people that made this possible.

After doing that, How do I choose my customized new button?

The above procedure activates the "A" & "B" hotkeys as an alternative means of going to the beginning/end of a marked section, in addition to the standard PgUp/PgDn hotkeys. There is no user button-config available in ADM.

I see that when I enable that option, not only A and B changes, also other shortcuts change right?

[eumagga0x2a]

Right. The currently active shortcuts are shown in button tooltips. All affected actions are listed in https://github.com/mean00/avidemux2/blob/master/avidemux_core/ADM_coreUtils/include/prefs2_list.h prepended with KEYBOARD_SHORTCUTS_ALT_.

I have to add that Kdenlive video editor has the feature of "loop zone" and it is also open source, I don't know if that helps.
