Please test BETA version 25.12

Some very good fixes plus some exciting growth for more professional video processing in Shotcut. This release is expected by the end of the month.

Please keep in mind that many filters are available in 10-bit now on the CPU. We have migrated nearly all that we can, but most of the ones that are not available are dependent upon a library outside of our direct control. And some of these (frei0r) require a major architectural change (not simply contribute enhancement), which is a big project and requires others’ approval.

When switching processing modes, the graduated filter changes significantly. The difference is only visible on graduated filters, a normal image shows virtually no difference.

upd. I think I figured it out, this filter doesn’t have 10-bit support yet.

After switching processing modes, some filters stop working.

    • I add an image
    • I add a filter, for example, SPR
    • I change the processing mode
    • I can’t move the image with the SPR filter

Hello

Added Settings > Processing Mode for video processing. This affects both preview and export.

The problem is, if we change the processing mode, the filters no longer react, even when switching back to the old mode used.

However, when closing Shotcut after changing the processing mode, and reopening it, the filters work on the new mode chosen, but do not react to another change of mode; it is necessary to close Shotcut after each change of processing mode.

Bonjour
mode de traitement vidéo (ParamÚtres > Mode de traitement)

Probleme, si on change de mode de traitement, les filtres ne reagissent plus, meme en remettant l’ancien mode utilisĂ©.

Par contre en fermant shotcut apres changement du mode de traitement, et en le reouvrant, les filtres fonctionnent sur le nouveau mode choisis, mais ne reagissent plus a un autre changement de mode,il faut a chaque fois fermer shotcut apres chaque changement de mode de traitement.

In processing mode,

With linear mode, color blocks can sometimes appear, especially in the shadows. Perhaps more so in dark red tones.

Switching to native mode makes these color blocks disappear.
With linear mode, in the scope, video rgb parade, streaks appear especially in low light.

Dans le mode traitement,
Avec le mode lineaire, des blocs de couleurs peuvent parfois se former, plutot dans les ombres. Peut etre plutot sur les teintes rouges sombres.

En mettant en mode natif, ces blocs de couleurs disparaissent.
Avec le mode lineaire, dans le scope, video rgb parade, des stries apparaissent surtout dans les basses lumieres.

Which one? This sounds like it might be 8-bit, and it is probably outside of our control. It has less precision.

8 bits and 10 bit.

CPU or GPU?

Minor typo in release notes (line 2 of screenshot):

Hello
CPU.

It seems the only way to access a 10-bit sharpening filter is to select Linear 10-bit GPU/CPU. This mode works well for me so far.

I have removed the Linear 8-bit processing mode for the release. We put it in the beta as an experiment because we did not have much time to assess things after pounding the code. Now, we agree it is useless and not salvageable. We have not found an issue with the Linear 10-bit CPU option, however. You can double-check that, but there is very little we are able to do further on that.

I am not sure it’s my PC or what, but the Snipping Tool in Screen Recording mode doesn’t work.

It does appear, you select your area to record, you start working on Shotcut then boom it won’t work, it just stop.

So i deleted the version (of Shotcut) and used the last month version, Snipping Tool worked fine.

I am not sure what’s the problem

It is working for me on Windows 11, and nothing changed in that area between versions.

Also using Windows 11, but to switch it off and on and i try it again. Thanks

@brian fixed this for the release. We also found changing other things in Settings can cause this and fixed those.

These processing modes (10 bit!) are awesome, massive thank you. Only issue I’ve noticed was my custom export presets produced color issues with the old “mlt_image_format=rgb” command (I noticed it was missing in updated presets, removed line, all seems fine now).

Export writes that option into the XML when you click the Export button depending on the chosen processing mode. But it only does that when a preset does not define mlt_image_format. Then, if you chose a linear processing mode, it adds another option mlt_color_trc=linear. Consequently, if your custom preset defines mlt_image_format=rgb and linear 10-bit is chosen, you actually end up with linear 8-bit in your export and you are back to the linear 8-bit mode that has been removed for quality per above comments. I will add some logic in export that overrides the mlt_image_format in that case.

I’m using Shotcut version 25.12.2 BETA on Windows 10 on an Acer Swift 1 (Dec ‘16) laptop.

Watch how copying and pasting (or shortcut B) a Colour clip creates a Video track.
