[Résolu] UI/UX Suggestions (or please tell me how to improve usability)

Hopefully, some one with more experience will address your slowness.  I do not see this on my laptop but I only load small videos and do not do any "real" editing - just testing of the new features or attempt to reproduce problems for analysis.  However, I will address some of what you mentioned.

1. Single screen versus multiple screens - Cinelerra has been around since even before 2000 when computers had less capability and it was designed with multiple screens.  It does not use QT (this is sometimes a source of consternation as it would be helpful in some scenarios).  There is a lot of benefit to having multiple screens that you may appreciate in the future when you get used to them.  BUT for now, use the Window pulldown on the main/timeline window and "Save Layout" to set up different window placements to use.  I have noticed that several users, tend to put the Resources window in the upper left hand corner, extend the Main window timeline to make it longer, and leave Show Overlays window up.  I do not see the possibility of a Single screen because the multiple screens is just too useful for us.

2. I think most users change the Settings->Preferences, Playback A tab, Video Driver to X11-OpenGL.  With a good graphics board, this should be helpful.  The default is X11.  There is also X11-Direct which for playback can really speed things up.  As far as GPU hardware decoding -- this can improve performance, but it is limited in the formats it handles depending on your graphics board and graphics software.  Recently we had been provided with a Drone output video and that video was "profile 66" and it produced the error "Codec h264 profile 66 not supported for hardware decode".

As always, more memory on your computer helps.  A really big help is to use "Proxy" under the Settings pulldown.  It is pretty well debugged.  "Tips for Using Smaller Computers" chapter in the manual (I think it is section 19.5) is not just for small computers.  For example, turn off the Thumbnails in the Resources window -- Settings->Preferences, Appearance tab.

P.S. We are unaware of any specific bugs having to do with performance.

3. I have no feedback on this at this time.

4. I have never heard any reports of the difficulty of using keyframes.  I will see if I can figure out why this may be difficult.

5. There are several ways to easily line up the edits but the "traditional" snapping is best described in a very short paragraph in the Editing chapter, section 5.7.9.  We added several shortcuts for these as described there:

snap_left_edit                  ctrl+alt+ ','
snap_right_label              ctrl+alt +shift '.'   shift+period is the > sign on US keyboards
snap_left_label                ctrl+alt +shift','    shift+comma is the < sign on US keyboards

We have a LOT of shortcuts so when Snapping and Snapping while Dragging were added, we had to make do with whatever we could use for characters.  It is easier for me to just line the edits up manually by watching the colors when in Drag and Drop mode (not the default mode which is Insert mode instead).  And there are other ways to tell when things are lined up next to each other in Insert mode when double arrows appear.

Hey, @phyllissmith! Thanks a lot for your reply. Sorry about the confusion, I thought Cinelerra was build using Qt, but in the end it doesn't really matter.

1. Sure, multiple windows has its advantages, but the title bars use lots of space... You can see in many videos/tutorials that usually part of the UI is covered by other windows when the screen isn't big enough. And being a single window does not mean that you cannot have floating windows (or panels) too. For instance, both Shotcut and Olive use a single window interface, but you can unlock the panels and arranje them as tabs in the interface, making switching between them very easy. Custom layouts help for sure, but I was suggesting something to improve the UI so it would adapt better for any screen size.

2. Yeah, I have tried all that as well as all the options from the manual regarding performance. The video play back is very good, but no matter what I do the program window is very sluggish, it is why I think there is something wrong regarding the UI specifically. As I said previously, simply scrolling the tracks up and down is painfully slow, or when trying to move clips is very slow too, even with all the options and settings to improve performance enabled. This happens even with and empty project with just a photo or a solid color in the timeline... If it helps, I can try to capture a video showing the problem, but right now I only have access to a very slow internet connection so it may take a while to upload the video.

3. Every time I change "Draw media" the program takes a long time to rebuild the thumbnails, and the same happens while playing the timeline and it scrolls, so maybe it is related to the slow performance somehow...

4. Maybe it is related to the slow response of my program window, but every time I try to create or move a keyframe in the timeline it is a pain: even if I make the program window full screen and the tracks taller, it is very hard to click on them without creating a new keyframe, etc...

5. Thanks for the shortcuts tip, I did miss them. Same about the "double arrow", I think I didn't understand how to do that yet, but I will look further. Anyway, I think the "snapping" feature with a toggle would be very useful, specially for beginners in the drag&drop mode, and probably it is a good idea to make it enabled by default.

Regards

On the left side in the patchbay there is a switch ("the eye") with which the graphical display of the media can be switched off. You have already discovered it and you should leave it off with your computer. Without this thumbnails the speed of editing is increased enormously. For beginners this is often irritating, because they orientate themselves on the timeline with this thumbnails, but with time you get used to it. By the way, these thumbnails only show the approximate position on the timeline, only the Composer display is correct.

Hi,
For performance try unchecked "Play every frame", it's an option that weighs heavily on playback. For playback only it is better to use X11; however if you add various effects then it is better to switch to X11-OpenGL.
What format and codec does your drone use? There are formats that give "seek" problems (for example mkv format, to me). In these cases it's better to use Transcode to make the media uniform to a more manageable format (some people recommend proxies in mjpg because they're very light and hassle-free).
Another workaround is to disable playback (from patchbay) of all tracks except the ones you are working on.
Last tip is to calibrate the cache to use. This takes a lot of testing and a lot of time and is done using the "top" console command, to check resource usage as you test.

1- Unfortunately the windowed interface is not editable because it is not based on GTK, QT or anything else, but on Guicast, personally created by the original developer. It's an old issue that everyone has faced sooner or later, but that would require rewriting all the code. However you are in a borderline condition, large screens and even multi-monitors are required for smooth video editing. Try disabling the windows you don't need and leaving only the Main and Compositor. Then, uncomfortably, turn up Resource and Viewer whenever you need them; even overlaying them with the ones you already have.

2, 3- A workaround could be changing the colors of the track (right click --> "bar color") to distinguish one edit from another. So you can leave only the title bar. For media recognition we have to go to the Resources window, maybe using the "Inter-view" view. Anyway the idea of leaving only the first and last frame visible is good; let's hear what GG says.

4- The only way I found is to be sure to position the cursor precisely over the point of the keyframe, and only then click. It's also a problem with the Mask tool, but I must say I've quickly got used to working with more precision.

5- Good idea to have a switch in Preferences to make the snap of the edits by default.

NOTE: if you want to make precise requests it's better to use the Bug Tracker, so that you don't lose track over time.

Thanks a lot for your replies, @Olaf and @andreapaz (by the way, thanks a lot about your video about the new release, that is why I knew about the user manual, it is great that you added EN subtitles).

Indeed I have tried most of the suggestions that you gave me, and indeed the only way to speed up the timeline in my case is by disabling the assets. For small projects it is not a big deal. My suggestions was more for improving Cinelerra GG even more, mostly for new users (if the learning curse is too steep then probably they will seek another alternative).

Too bad that it is not possible to implement a single window mode. I can deal with a few windows and different layouts, that is one of the good features of the GG Infinity version. 

As I was not sure if these issues are related to my configuration/setup I though it would be better to post here in the forum for discussion first. If specific items can go to the Bug Tracker, I will gladly add them later.

Regards.

@LFOM

Just out of ignorance on my part what is this thing? -- "single-user build for Eoan on Pop!_OS 19.10"  -- I mean which operating system build?

Some more feedback:

I have logged a Bug Tracker issue #392 for looking into the possibility of adding an option for Single window after talking to gg.  It is not out of the realm of possibility but of low priority.

Also logged BT #393 for an automatic "Snap" option preference, but gg is not sure how this should work.

Finally, gg wonders if there is anything unusual about your media -- drone 720p 25fps should not be performance issue. If you have an example of one that goes slow, he could at least look at it to see if it is a problem here if you want to put it somewhere where he can grab it.  Or send it to my email if it is private so it will not be shared: [email protected]

Pop!_OS is based on Ubuntu, so version 19.10 > Ubuntu 19.10 = Eoan Ermine, so I have installed "cinelerra-5.1-ub19-x86_64-static.txz".

Thanks for the replies and time for adding the Bt issues, I do appreciate it. The problem isn't the media. As I said before, even if I simply add a photo or a color frame/title using the filters anything I try to do in the program window (where the timeline is located) is very sluggish. The only way I could use the program is by disabling the assets (all tracks show only their name/label), but them it is very hard to adjust keyframes, etc...

You might want to try starting up CinGG from terminal, to see if there are any "strange" messages that might reveal something. Otherwise, there's a real debugging to be done (gdb, valgrind?). But this is beyond my skills.

Does this apply to your PC?

If an Nvidia graphics card is installed, are the original drivers installed or the combination Nouveau/Mesa?

You might want to post here the output of "inxi -F"

@andreapaz

No errors at all. I am running Gnome on Wayland as it is way faster than X11 for normal tasks (web videos, scrolling, etc), but I have also logged in using the normal X11 system and it was the same.

Again, just to make it clear: video playback and UI works fine as long as I don't do anything related to the program window itself (timeline). I have created proxies (Cinelerra GG Infinity handles them pretty well, automatically) and optimized the program for my hardware using the tips from the manual and the forum, and it works great until I have to move a clip in the timeline or try to create/move a keyframe, that's why my post is about the UI/UX. Other programs are usually the opposite: using the timeline is normally snappy.

@olaf

Yeah, sure. And it has no hybrid graphics, it uses the Intel HD video driver only (what works acceptable with Wayland and vaapi).

But, again, it is not the issue: how Cinelerra GG Inifinty handles the media isn't my issue, far from this (it is actually the best NLE for this, because of how it handles proxies), but using the timeline, specifically, is very sluggish for me. If I simply open Cinelerra GG with a brand new empty project and just add a simple title I have the exact same issues. Sure, if I disable everything in the timeline and see only the clips titles it works in an acceptable manner. I was not sure if it could be improved or not. If you say that's how it works, then OK, I am simply suggesting that it maybe could be improved to help new users and/or improve usability, as my suggestion to add an option to only show the first and/or last frame for each clip in the timeline (a cache can be used, speeding up things, perhaps).

Hey, I think it was you that left a comment in that itsfoss.com article that made me install Cinelerra GG Infinity. Thanks!

Again, I know that my hardware won't run Cinelerra GG Infinity at full speed, the intuit of this post is to improve/enhance the UI/UX usability, maybe from the perspective of a new user. Hopefully I will be able to capture a video showing the issue and I will post it here soon. Thanks again for all the replies.

@LFOM

I forgot to provide feedback on this suggestion -- "to add an option to only show the first and/or last frame for each clip in the timeline" -- GG does not see this as feasible from a programming viewpoint or from a user viewpoint as quite often both the first and last frame are just black.

I wish we could see what you see because there is no way for the programmer to fix something if he can't reproduce it.

@phyllissmith

I see.. But even if it's just a full black thumbnail, it would make it much easier to see the junctions of clips, wouldn't it? And it not always black (in my experience, once you starting creating the clips for the timeline they hardly are black. Anyway, I don't know how it was coded, but using a cache for both starting and ending thumbnails seems like an improvements, instead of rebuilding all of them (if they are already cached, then I don't know what to say)...

Sure, I will try to make a short video showing the problem. Is it OK to compare it with another program, so you can see how it works? 

Regards

@LFOM

We are not familiar with actually using any of the other NLE's and purposely stay away from them so we do not copy their work.  But It is OK to compare a demo with another program so we can see the difference.
