What I see immediately in your video is that it did not create proxies when it added to the playlist. It should have. I found a code in File > Open multiple that went missing after code merging process. That is fixed for the next version.
I have not yet reproduced the proxy job failures. We would need to see the logs of them. I just tested proxy of an image with odd width does work.
after the slideshow was created there was an issue with image sizes
I think there is a problem with dynamically swapping the image with its proxy. I reproduced it but still debugging.
However, after export: result of exported Mp4 was blurred when viewing full screen (360p, not 1080p).
It’s as though the proxies are not being replaced by the originals. Is this a bug or am I doing something wrong?
Of course, the proxies should be replaced by the originals, but I did not reproduce this problem yet either. I would need more details like media properties of this exported file, and perhaps try to figure out at which step the problem is introduced. Did Export > Video show the intended resolution? I tested after step 3 as well as a few things from step 4. It is not necessary to turn off proxy but also I tried export after turning off preview scaling and proxy. Were you viewing the result in Shotcut with preview scaling turned on?
I don’t mind sharing the images to see if you can reproduce the problem if that helps. I’ve put them into 2 folders to keep the file size down to under 4Mb.
The images that caused the proxy creation to fail were 1, 6, 9, 11 and 12.
There’s something weird, too.
On the video above (post 29) you can see that I uploaded 7 pictures in the playlist.
In the work view there are 10 tasks ???
But I did all of them live ???
If it can help you
Everyone, please wait until a new beta is posted before reporting any more bugs with PROXY.
Feel free to test other things and report on them. Until then any replies on that subject will be ignored.
Merge with next clip issue.
Put a clip on the timeline add a filter to it, split the clip. Use merge with next clip, the filter is duplicated. Every time the clip is split and merged the filters are replicated. Demo.
strangely but similarly, the Properties > Show in folder does not work
I cannot ask the Proxy to be computed for more than one item (or at least I could not find how). When selecting multiples items in the playlist, there ws not contextual menu to perform the same action on those selected items, i.e. make a proxy.
I really think adding the Proxy menu on the right click menu should contain those proxy related actions
by mistake, I moved a proxied file from a track to another one (from #2 to #1) … I saw my mishandling, did CTRL+Z … it did no do anything, I put it back to its place manually by drag & drop … since the, the file cannot be played (black), regenerating a proxy does not work (error log says (…) proxies/04860c33160327032ab72e22928481a8.mp4: No such file or directory)
and the file, in the track appears with the proxyname, not the actual filename … I disabled the proxy, to no avail, then deleted it and tried to regenerate it … to no avail as well …
At one point I got a crash : disbaled proxy + deleted it + tried to re-enable it : it crashed
when I reopened my project (not save since the beginning) all was fine
ENHANCEMENTS IDEA
add a visual hint on the timeline to know a clip is using a Proxy (i.e. a file exist for it and it’s being used). The background color could be slightly different, or a tiny icon be added, or a suffix added next to the clipname, like filename.mp4 (proxy).
once again, I tried to to something on a clip and intuitively looked on the right-click menu on the timeline (this time to generate the Proxy) … I think the contextual menu on the elements of the timeline could really be enriched
I have a powerful computer : could the proxy be set with a bit higher quality (this could be a well hidden setting, but I set 720p as proxy+scaling preview … and it’s really smooth. I feel I could push it further with slightly biiger proxy files using a better quality (higher CRF)
QUESTIONS
can the proxy format be chosen ? I have an H/W compatible encoder, and it can perform HEVC or X264 … but I’m not sure enabled means “selected”. I see the proxy are in HEVC, but I wonder if using x264 would not be even smoother in playback / lighter in terms of performances.
@DRM : you are right. I may have scrolled to the bottom of the thread a bit too fast.
Sorry @shotcut … I still report not proxy-related bugs in my first post
Merging does not know which filters to keep. It does not know that the filter on the second clip was from a split. After merging you need to decide which filters to keep. This will not be changed.
This is an old bug on some Linux builds and desktop environments. I do not know why. We simply make a high level call in Qt, and then it is largely out of our hands. Perhaps a future upgrade to Qt will make a difference. For me, on Ubuntu 20.04 with GNOME Shell, it works in Flatpak and AppImage as well as my local compile. There is probably a file missing in our portable and snap, but I do not know.

Covered in the docs (below), but turn off hardware encoder for x264.
