Some things to report on:
There seems to be a bug with the “Mask: From File” filter when the Invert box is ticked. If you pick any one of the transitions while having the effect inverted and crank the Threshold all the way to 100% it goes back to the same inverted image at 0% rather thanthe image that is coming in with the inverted option on. So in other words, when you don’t have the Invert option on, the image at 0% and 100% Threshold are different. With the Invert option on, the image at 0% and 100% Threshold are the same.
The “Mask: From File” and “Mask: Simple Shape” filters act strangely with simple keyframes. With any other filter the first keyframe in simple keyframes will be whatever was set in the timeline. So for example, if you pick the Brightness filter and in the timeline you set it to 200% then go to the simple keyframes, the first simple keyframe will be at 200% while the first frame of that clip will be the default 100% setting. So the clip will have a Brightness that goes from 100% (the default) to 200% (the value set in the timeline). The two Mask filters though do not behave this way.
With “Mask: Simple Shape” you don’t even have to set any values in the timeline for it to act strange in simple keyframes. If you apply the Simple Shape filter (along with some other filter like Brightness and “Mask: Apply”) then go to simple keyframes and just double tap the first simple keyframe to jump a second then for whatever reason the rectangle shape goes to the top left hand corner on both the first frame of the clip and the first simple keyframe. If instead of double tapping the first simple keyframe you drag it out then the first frame will stay at the default position but the first simple keyframe will go to the top left hand corner.
With “Mask: From File”, instead of the first simple keyframe being at whatever the Threshold was set to in the timeline (e.g. Threshold 100%) and the first frame being the default Threshold setting of 50%, both the first frame of the clip and the first simple keyframe will be the same setting that was done in the timeline (e.g. Threshold 100%).
- I was testing the new Ut Lossless preset by taking some 4K and 1080p files and bringing them down to a proxy file size of 360x204 but when I bring the finished file back into Shotcut for some reason Shotcut’s player keeps flashing some green video glitch on the left side of the screen throughout the duration of the video. Here is a screenshot.
This didn’t happen with the previous Ut Video Lossless preset. It also doesn’t happen with the current Ut Video Alpha preset.
