Again, trying to find a suitable video editor.

Hi,

I simply can't find a suitable video editor that works.

My goal is to extract the interesting parts of a TV recording. Ie, mark
the start of the movie, the end, the commercials inside, and dump all
that into a single file, perhaps recoding.

One limitation is that movies here have two sound tracks, one in
Spanish, and the other one in the original language, typically English.
I want to keep both, obviously.

I don't need any transition or effect, just a simple editor that allows
me to remove unwanted sections.


I have tried:

pitivi - crashes on start

LiVES - works for an hour at 100% CPU and can't load the file.

dvbcut - says my mpeg file is not a video (and it certainly is!)

tragtor - can convert, but not edit.

openshot - almost. My video has two sound tracks, and this tool ignores
the second track.

cinelerra-cv - I can't make head or tails of it. I tell it to load a
video file, it does, but then I don't see how to do anything. It doesn't
even display the video. I may have to read the manual, but I dislike
having to read a manual for a GUI. Still...

kdenlive - Well... crashes too often. I can mark the cuts, but it does
not display what I'm cutting. And only one sound track.

HandBrake - no edit.

Avidemux - one sound track only.

Kino - abandonware.

Lightworks  ??

Shotcut - Segmentation fault on start.

  cer@Telcontar:~/Videos/Fusion/trabajo> shotcut
  QSqlDatabase: QSQLITE driver not loaded

  QSqlQuery::exec: database not open

  Database version is 0
  Segmentation fault
  cer@Telcontar:~/Videos/Fusion/trabajo>


Flowblade ??  I don't understand the tool. May need some reading. At
least it runs.




I would like something that would produce a command line to ffmpeg in a
GUI. Then I could modify further the options. This would be ideal.
tragtor works this way, but has no editor.

Same here, though I never tried as hard as you obviously have, and not since
more than a year ago when...

> (from 13.1 x86_64 "Bottle" at Telcontar)

...I was running 13.1, or maybe before that, was when I was still running
11.4. I recently moved to 42.1 on this machine, but I have every OS release
multiply installed on others.

Shouldn't be so hard to find something that just works - seriously. Digital
video's been around a long time. Still...

1-How old is your machine? Intel, or AMD CPU? Shouldn't make a difference,
but maybe? Is it one that sports more than one hardware audio "device"?

2-Exactly how are you capturing, and into which file/container type? Those I
need to edit AFAICT are raw transport streams, .ts files saved by DVB
satellite receivers.

3-Could those crashing be victims of Packman build and/or versioning problems
that might go away after some time passes and updating?

4-Could those crashing be interface type victims? Maybe try them in a
different DE session type, XFCE instead of Gnome, LXQT instead of KDE??? Use
gtk interface rather than qt, or vice versa?

A few years ago I used kdenlive with success, but did not need two sound
tracks on a machine with 4 cores and 4 GB memory. If I remember right,
kdenlive just produced a job which got executed when finished and one could
postpone the execution, making it possible to change the job.

I use kdenlive without problem for at least two years now (13.2, Leap),
but for your language problem, I don't know. Avidemux (given his name)
should do the job.

If you can have video + langages, simply paste them in kdenlive audio tracks

No, avidemux only reads one sound track from the mpeg file. It wants a
second sound track to be on another different file.

How?

The source mpeg file has one video track and two sound tracks. I want
all three in the resulting edited file. Kdenlive ignores the second
audio track.

I could try on Leap, but I don't expect much difference. Multimedia
software typically comes from packman, with some exceptions.

It is a intel core duo with 4 cores, and 8 GB. Not young, but still
powerful. I can convert 4 movies with 4 simultaneous ffmpeg processes
in a reasonable time. The HD also imposes a limit on video conversion,
and the machine has a minimum of 4.

In this case, it is also transport streams, but coming via fibre,
generated by kodi with a special plugin that talks with my provider.

Dunno. Maybe. Some of those crashes I have seen for months.

I was reading a magazine comparison article on video editors for
Linux, and the chap said that kdenlive crashed a lot on the distro he
was using and had to use another distro where it was stable. I'll post
the link later, it is on another machine.

I'm using XFCE...


The last editor I'm testing is flowblade. I told it to convert a clip
of 5 minutes, and it has been chugging along for 95 minutes already. I
must have done it wrong. I read the manual and didn't understand a
thing: plain text manual in html with no figures, no samples. Just a
text description valid for people that already know how to use a video
editor. :-/

Yes, that one. My link is:

http://www.theregister.co.uk/2015/12/26/linux_video_editors/?page=1

It is working fine here, all four pages.


And... flowblade also used only one of the sound tracks and ignored the
rest. :-(

I want to try "gopchop" (http://gopchop.sourceforge.net/). I don't find
it ready built. So I try to build it. Configure fails here:

checking mpeg2dec/mpeg2.h usability... no
checking mpeg2dec/mpeg2.h presence... no
checking for mpeg2dec/mpeg2.h... no
configure: error: Couldn't find header mpeg2dec/mpeg2.h!
cer@Telcontar:~/Compilaciones/MultiMedia/gopchop-1.1.8>

It probably refers to "mpeg2dec - MPEG-2 Decoder" available in packman,
but the -devel package, which is missing. I installed
"mpeg2dec-debuginfo", but no go. I will have to install that one from
source, too (http://libmpeg2.sourceforge.net/)

Ok, I built it. I'll continue tomorrow.

I know that you state below that you tried Cinelerra
(https://en.wikipedia.org/wiki/Cinelerra) but believe me this is the one
that you want to use. I have used it to edit recorded movies (removing
commercials, eg) and it is the ants pants for editing videos. Spend just
a LITTLE bit of time to read how to use it and you will not regret the
time spent.

mpeg2dec built and installed successfully (without an rpm, 'make install').
However, "make gopchop" produces C syntax errors with which I'm not familiar:

It does not have a "help" menu entry. What do I read?
Just resize the "compositor" window and I see redraw artifacts: bad coding.

I just told it to load a video (12 GB), and after a few minutes it still
hasn't finished opening the file, nor do I see any change in the
display. Ok, it finished loading, but I do not see any preview anywhere.
I don't see where to move forward and backward to set the cut points.

I enter what seems cutpoints, and instead what it does is draw a
waveform with the mouse. WHAT?


This is WAY OVER MY HEAD!

I just want a SIMPLE editor to remove regions of the movie, not a
zillions windows and options I can't understand at all.

A the list of stating a war, I/we use Pinacle in Windows to edit shows
for our TV station. Quick and simple. I've never seen a video editor for
Linux that can come close for ease of use.

It's all here:

http://heroinewarrior.com/cinelerra/cinelerra.html


Don't get frazzled. Sit back, take a deep breath...and read (at least
the top part of) https://en.wikipedia.org/wiki/Cinelerra .

Cinelerra is really worth the trouble of finding out on how to use it.
And it isn't that difficult -- but it is not designed for use by script
kiddies.

Carlos,

I've done all you describe using kdenlive. More than any other application
kdenlive needs its deps and recommends and it's own package to be from the
Packman repo.

Well... At this point I consider everything, but this desktop computer
is not double boot to Windows, My laptop is, but not powerful enough for
video editing all day.

The code section was:


char *GOPchop_cvsid = "$Id: Main.cpp 346 2009-03-02 23:26:02Z keescook $";

I change it to:

const char *GOPchop_cvsid = "$Id: Main.cpp 346 2009-03-02 23:26:02Z keescook $";

and make is happy on this one after also changing that declaration in the main.h file.


The next one, an error, not a warning.

Main.cpp:139:1: error: C99 designator ‘video_driver’ outside aggregate initializer
 };

The code is:

global_options options={
    run_loop:             0, /* don't wrap arround by default */
    run_speed:            1, /* one frame at a time by default */
    default_run_speed:    1, /* one frame at a time by default */
    auto_refresh:         1, /* show gop position changes by default */
    ignore_errors:        0, /* don't ignore errors by default */
    drop_orphaned_frames: 0, /* orphaned frame dropping can be nasty */
    adjust_timestamps:    1, /* adjust by default */
    video_driver_ptr:     NULL, /* prefered video driver */
    video_driver:         "\0",
    force_system_header:  0, /* force prepended system header pack */
    drop_trailing_pack_with_system_header: 0, /* drop final pack if it has a system header */
    ignore_endcode:       0, /* don't stop parsing when an End Code is seen */
};

What do I do here?
I think it refers to this one:

 video_driver: "\0",

Let me see... the declaration is:

typedef struct
{
    gboolean run_loop;              /* when in "Run" mode, wrap to beginning at end */
    int      run_speed;             /* how many GOPs to jump forward during "run" */
    int      default_run_speed;     /* the speed to start with upon load */
    gboolean auto_refresh;          /* redraw the frames after moving the slider */
    gboolean ignore_errors;         /* don't store errors about file loading */
    gboolean drop_orphaned_frames;  /* get rid of starting B frames on an open GOP */
    gboolean adjust_timestamps;     /* adjust the GOP timestamps as we write clips */
    gchar*   video_driver_ptr;
--> gchar    video_driver[24];      /* this is the name of the video driver to use */
    gboolean force_system_header;   /* should a system header be prepended */
    gboolean drop_trailing_pack_with_system_header;/* should final pack with a system header be dropped? */
    gboolean ignore_endcode;       /* should parsing continue past an end code? */
} global_options;


I have no idea what to write instead of

 video_driver: "\0",


(that is the remaining hurdle)




Next.

Main.cpp:152:1: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
 };
 ^

code is:

rc_parse_item parsable_items[] = {
    { "run_loop",             &options.run_loop,             RC_TYPE_BOOLEAN },
    { "default_run_speed",    &options.default_run_speed,    RC_TYPE_INTEGER },

    { "ignore_endcode",       &options.ignore_endcode,       RC_TYPE_BOOLEAN },
    { NULL, NULL, 0 }
};

main.h:

extern rc_parse_item parsable_items[];


rc.h:

typedef struct rc_parse_item_t {
        char * option;   /* name of the rc option */
        void * variable; /* variable to load into */
        int    vartype;  /* type of option to load */
} rc_parse_item;

So I guess I have to change to:

const char * option;



I make. One error remains:


Main.cpp:139:1: error: C99 designator ‘video_driver’ outside aggregate initializer
 };
 ^

(this one is already above, and I don't know what to do about it)




Next one is a warning:

Main.cpp: In function ‘void handle_rc_load()’:
Main.cpp:828:39: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
     if (rc_load(PACKAGE,parsable_items))
                                       ^

The code is:


typedef struct rc_parse_item_t {
     const char * option; /* name of the rc option */
     void * variable; /* variable to load into */
     int vartype; /* type of option to load */
} rc_parse_item;

...

int rc_save(char * package, rc_parse_item * items);
int rc_load(char * package, rc_parse_item * items);

...

rc_parse_item parsable_items[] = {
    { "run_loop",             &options.run_loop,             RC_TYPE_BOOLEAN },

    { "ignore_endcode",       &options.ignore_endcode,       RC_TYPE_BOOLEAN },
    { NULL, NULL, 0 }
};


    if (rc_load(PACKAGE,parsable_items))
        fprintf(stderr,"%s",_("Could not load rc file -- using defaults.\n"));


I don't understand why it is giving a warning there :-?

I have it from packman.

Besides crashing too often, I find it difficult to cut out the exact
regions, and even if I get that far, it ignores the second audio track
on conversion.

I'll try again.

I load the video. If play automatically is selected in the open file
dialogue, the application crashes immediately.

I see a clip monitor window at the top right, so I try to use that. The
video I'm trying has 3 hours. I have to go to the start of the
appropriate section with the mouse. To select the exact frame I would
use the keyboard, but it doesn't respond. There is a little box on the
right where I can select the second with the keyboard, but the image
doesn't update till I release the keyboard.

I then hit the "[" miniicon to signal that I want the start point just
there. After some experimentation it does just that, but there is no
visible sign in the slider till I also signal the end point somewhere.

I drag that to the "video 1" slider. It is a 10 minutes cut for testing.

I hit "render". I select Matroska, which I know for sure it supports
several audio tracks. Running, start 13:22, Estimated time 36:18 -
that's a lot for a ten minutes video, ffmpeg is faster.

Finished in 59 minutes, at 14:21 hours.

I got "untitled.mkv", and it only has one audio stream (English is
missing), so it is of no use to me. I absolutely need both Spanish and
English audio in the same file.

I can live with a slow program, but not one that doesn't produce the
expected result.

Google.

Huge manual full text, few images. I read a bit.

Ok, I load my video.
If I press the "play" icon, should it play? It does not.
In the track timeline windows I only see Audio tracks, and a flat audio,
no waveform. I can draw my own waverform with the mouse, whatever that
is good for...

In "viewver", play does nothing. Moving the romboid slider does nothing.
I assume it should display images from the video, but it does not.

I try another movie, much smaller. Same thing, nothing is displayed.

I can't do anything with this software if I simply can't view the video...

http://heroinewarrior.com/cinelerra/cinelerra.html#LOADING-FILES


+++-----------------
7.2 LOADING FILES

All data that you work with in Cinelerra is acquired either by recording
from a device or by loading from disk. This section describes loading.

The loading and playing of files is just as you would expect. Just go to
file->Load, select a file for loading, and hit ok. Hit the forward play
button and it should start playing, regardless of whether a progress bar
has popped up.

Another way to load files is to pass the filenames as arguments on the
command line. This creates new tracks for every file and starts the
program with all the arguments loaded.

If the file is a still image, the project's attributes are not changed
and the first frame of the track becomes the image. If the file has
audio, Cinelerra may build an index file for it to speed up drawing. You
can edit and play the file while the index file is being built.
-----------------++-


Well, it does not do what the manual says. It thinks for a while
apparently loading the video, but refuses to play it. I guess it does
not like the format, but doesn't say anything. No error displayed. No
video displayed, no audio displayed, and it does not even play.

If I define a new project with one video track and two audio tracks,
then load a video, after loading it, resets to 4 empty audio tracks.


And of course, the input video file can not be changed, it is what it
is. Plays fine in vlc, mplayer, xine...
