All, I have a MP4 that plays fine in Kaffiene (openSUSE 13.2 + Packman). I'd like to be able to pull a snippet out of the middle. Basically just crop of the start and end. Is there something in openSUSE and/or Packman to do that?

I'm not expert in this field, but have You tried Kdenlive? It should be sufficient for Your needs.
Thanks Greg

there are many :-) but it's not always as simple as that, for reasons too long to be explained now. * if it accept to work, the simpler application is avidemux. Be kind to cut *on master frame* (I'm not sure of the english name), that is use the double arrow to search the exact frame, select the entry point, clic on "A", the out point, clic on "B" then record (the floppy icon), tat's all, the default setup is "coy". do not forget the "pm4" after the out file name, avidemux do not add it automatically. this allow cutting without recoding, but it do not work at the frame level but at the master frame level - if you cut at the frame level, the video may be unreadable by some software * use kdenlive. add your video as a clip, drag it on the timeline, go at the start point, select the video and make "shift R" to cut. Remove (select, delete key) the beginning, select the end point, shift R to cut, and delete the end drag the remaining video up to the start of the timeline, and clic on "render" (red point). Then you have to choose the out format, do setup only two parts: quality of video and sound. this recodes the video jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't think so (with kdenlive). In fact clipping without recoding is more difficult than could seems at first. * a video is usually not (the exception is motion jpeg) made of real images. Most video compressing algorithm record an image by only keeping the difference between two successive images. In case of static scene, it's very efficient. * from time to time (every 30 images, for example), a full image is kept, it's called "key frame". * if you cut the film between two key frames, without any calculus, some images can't be calculated and drop, ma be the video in not readable at all. Else the software have to build a key frame around the cutting point That said, it should be possible to recode once the video to mjpeg (one jpeg file per image) or with each frame as key frame Avidemux allows cutting where you want, on a keyframe or not, you get the result you ask for, it's sometime necessary to have frame accuracy (not always possible), but if you want the video to be readable, better use the "key frame stop" avidemux provide (the double arrows) that said, the recode algorithms are very good and the loss minimal jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ah, yes. It makes sense doing so.
* from time to time (every 30 images, for example), a full image is kept, it's called "key frame".
It should be able to cut right at that frame, right?
Avidemux allows cutting where you want, on a keyframe or not, you get the result you ask for, it's sometime necessary to have frame accuracy (not always possible), but if you want the video to be readable, better use the "key frame stop" avidemux provide (the double arrows)
Yes, but avidemux often crashes or has other issues. But I was rather more interested in taking video pieces taken with a compact camera, and join all the pieces, maybe remove parts. kdenlive does this nicely. But I don't like doing it with a lossy process.
that said, the recode algorithms are very good and the loss minimal
Well, an option to click and choose "optimal recoding" would do. So that it chooses the right options to minimize them: size, codecs, frame rate, etc etc. - -- Cheers / Saludos, Carlos E. R.

If you just want to cut out parts of MP4 files, try gopchop. It is
fully lossless. It copies video segments between GOP markers in the
source stream. So it is also quite fast as it does not need to
decode/encode anything.

I wanted to do essentially the same thing, but with video streams saved to disk by DVB FTA receivers that either or both of VLC and SMplayer will play. I had some time back tried Kdenlive, but it apparently couldn't handle the particular .ts file format. I tried various other apps, but either I couldn't figure out how they worked, or the had the same problem as Kdenlive. Someone in the FTA forum where I asked who was doing the same thing I wanted to do but using some debian recommended avidemux-qt. I tried that, from Packman, but it gave no sound output, on 13.1, 13.2 and TW. Then I determined that avidemux apparently needed a configuration change. It defaulted to using pulseaudio, which I avoid installing except as last resort, and then only if it is known to be an only possible fix. I changed avidemux to use alsa instead, upon which avidemux would start to play video and sound correctly, then lockup completely and indefinitely, requiring kill -9 to quit.

You need Cinelerra if it is a video which needs editing. (Cinelerra, the ants-pants of video editing.) However, I think that you are only talking about a piece of mp4 'music' file in which case you need audacity. (Audacity, the ants-pants of audio editing.) Both Cinelerra and audacity are listed in YaST and both come from pakman.

Thanks Greg -- Greg Freemyer Hi Greg,
If I may I'd like to add a few options to the already extensive list of options that people gave you here. If you want to edit video's from the CLI I recommend FFmpeg. It has everything you need and a huge lot more. https://www.ffmpeg.org More on the professional side, there are Lightworks: http://www.lwks.com/index.php?option=com_lwks&view=download&Itemid=206&tab=1 If you have used editing programs before on other platforms, this might feel a bit weird in the beginning. And the most professional is Nuke Studio: https://www.thefoundry.co.uk/products/nuke/non-commercial/ There's a free version for non commercial use. For Linux this is the best option there is. I use this on a daily basis myself. I have used all three on OpenSUSE 13 and haven't run into any problems so far... greets Arno -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hi jdd I have to admit I never used the rpm... I am one version behind since Nuke Studio came along and always used the .deb with dpkg...

It's a little larger, but just a simple for cropping scenes. I know you don't want to hear it, but cinelerra will do it as well. I gave up on most others due to the lack of reliability. With cinelerra, you just load your video into the timeline, set your in/out points and render. It has a good render interface allowing you to choose the enconding you like. Plus, if you do get a bit more ambitious in the future, you will already have the basics out of the way :p -- David C.
