Paulo José Oliveira Amaro (pauloup) added a comment to T48912: Simple video load cut video strip in 6725 frames.

Hi Marcelo, I'm not a developer, but maybe I know what is happening. A video strip shorter than the audio strip indicates that the video source's frame rate is different from the blender project's. To fix it, if it's the case, you can try one of these:

  • Match the project's frame rate to source video's: In the Render settings of Properties Panel, set the Frame Rate to half of its current value.
  • Match the strip's frame rate to project's: In the Edit Strip panel, set the video strip's length to the correct value (13450) and then add an speed effect. This effect adjusts the video speed automatically.

Paulo José Oliveira Amaro (pauloup) added a comment to T36263: Pasted strip doesnt have F-Curve keyframes from the original.

Could it be fixed rewriting the copy/past operation to:

  • store references to the selected strip(s)
  • to paste, use the duplicate operator on copied trips and modify their start frame, channel and scene owner when it's needed.

?

Paulo José Oliveira Amaro (pauloup) added a comment to T47961: Wipe Effect does't work because its struct has only 1 input.

Please, test this .blend. It has two Wipes effects.



Wipe in channel 4 (displayed in the main preview) was created from Red strip (bug).
Wipe in channel 3 (displayed in the top small preview) was created from Red and Yellow strips (correct)
Even with alpha over blend mode, the Wipe from channel 4 shows no wipe at all (because Wipe effect doesn't generate alpha channel). So it's useless.

No, Wipe is not a single strip effect. See the wiki references and Youtube videos using it.
"The wipe effect is a type of transition strip. It can be used to transition from one strip to the next. The wipe will have no effect if created from a single strip instead of two strips. "

@Ejnar Brendsdal (ejnaren), it seems your doubt is similar to @codemanx's one. Maybe you're thinking about the "In Out" mode of sine. (See easeInOutSine here). The easing icons represent the "In" mode only.

Paulo José Oliveira Amaro (pauloup) added a comment to T39916: Make easing equations to follow the curve start point normal.

I see what you're saying and the envelope comparison is very meaningful. My concern is that the Bezier envelope would over increase the start of the Bounce curve. So the result start could be greater than the desired and maybe it doesn't follow the normal:


I'm not sure about it, It just seems the case because my understanding about the envelope is that it's just a multiplier vector, not a limiter. I'm just supposing, the actual result can be different.

Paulo José Oliveira Amaro (pauloup) added a comment to T39855: Icons for Robert Penner easing equations.

Hi @codemanx, I tried to represent the In mode in these icons, so they are Bounce In and Back in. I believe they match to the reference in: http://easings.net/
Maybe Bounce should use the Out mode. I thinks it's used more often, I'm not sure if it applies to Back also. Therefore it would make it inconsistent to the other modes.

Paulo José Oliveira Amaro (pauloup) added a comment to T39855: Icons for Robert Penner easing equations.

You're right about icons M16 and M25, they have a lightgrey degrade to blue. The easing icons could keep this style, but it actually decreases contrast between the affected part and the rest of the curve. It seems to me the darkgrey / blue curve works better, so in this new proposal (v4) I've just bright them a little. But I can change it if you still think different.

Paulo José Oliveira Amaro (pauloup) added a comment to T38018: Histogram don't takes Dither into account.

You pointed things that just don't work the same way in my experience. Many cinematographers are using DSLR footage (lossy 8bit, not raw video) for a long time, essentially for grading in post production. There's a topic on the DVXUser forums with many examples and information. Technocolor even created a color profile called Cinestyle for Canon DSLR that saves footage in an almost LOG space intended for grading purposes. Canon did it too recently. The downside effects of doing this are very knew (here, here and here), but the advantages are great, most to retain more information on shadows and highlights.

Paulo José Oliveira Amaro (pauloup) added a comment to T38018: Histogram don't takes Dither into account.

@Sergey Sharybin (sergey), I call it a problem because it affects a lot the way Histogram looks like, and then it affects the analysis. See the peaks in the VSE histogram. Some of them are not true peaks, they are artefacts caused by lost of information - that you mentioned -, but are not visually perceptible in the image. So if you see them in the color correction process, it may be unclear if they are caused by the round errors or are real peaks (that should be decreased - by changing all your color correction - to avoid to left the image unsafe (i.e., overflow the allowed light intensity limit for a broadcast).

Paulo José Oliveira Amaro (pauloup) added a comment to T38018: Histogram don't takes Dither into account.

Since banding effect (in this case showed by the histogram) is inevitable, Dither can help to minimize the problem. And see it through the histogram would be a way to know how much it can help, and this way, to know how much it is needed.

Paulo José Oliveira Amaro (pauloup) added a comment to T38018: Histogram don't takes Dither into account.

Yes, this is very common problem. In Gimp I usually overlay a noise texture layer to the image, which is almost the same than applying Dither in Blender.

Paulo José Oliveira Amaro (pauloup) added a comment to T38018: Histogram don't takes Dither into account.

@Brecht Van Lommel (brecht) If a gradient is 8bit (like the png image I used), this is the depth of colours, right? Its represent the quantization for the original color information. When I applied the Curves Modifier, it maps these values into another values. And as you can see, I actually increase contrast of the image, so a value of 35 before it became now 0, and a value of 235 became 255. So I think this make some pixels that was close (spatially and in value), with values like 200 and 201, become separated in value after the modifier is applied, turning into 199 and 201. This way, none pixel has the value of 200 and there's a gap in the histogram for the 200 value. This is the cause for gaps.

Thank you for the explanation, @Sergey Sharybin (sergey). I think just now I understand why Dither has to be the last step. But I still think it should be applied before histogram analysis, otherwise we can't know its effectiveness in removing banding.

Thank you! That's a non obstructive bug, since I can still watch the Histogram in its "filled mode", but I hope it can be fixed.

Yes, I hope it help you.

If there anything else I can inform, let me know.

@Brecht Van Lommel (brecht), Dither also can be used to add noise to a flat image. In my case, I play with the Curves modifier on a H264 video strip, witch creates bands on histogram. With dithering I can reduce banding effect, adding noise with dithering. But it only works with "Convert to Float" enabled, what is no intuitive at all.

Paulo José Oliveira Amaro (pauloup) added a comment to T38004: The size of Waveform, Vectorscope and Histogram is not correct in Sequencer.

I can't edit the Task, then I'm correcting here the ideally dimension for Vectorscope:

  • Vectorscope: fixed square aspect ratio with the maximum resolution that the scene allows (as it is on UV/Image Editor).

Paulo José Oliveira Amaro (pauloup) updated subscribers of T37982: File Browser options minor UI improvements.

Maybe it's helpful to update the lists layout to the new lists layout of Blender (i.e. used in UV map list), to include the max height delimiter and the filter options, putting the buttons aside the list.

Thank you! True, it seems quite simple and very efficient (in memory terms) what multicam is doing. The fact is that I didn't know it, even after years of using blender to video editing. Shame on me... :-P

Off-topic: Blender is - with NO DOUBT - the program with more resources I'll ever know! Never mind would be so easy to change between cams, as it is by just pressing number keys while playing back!

@Peter Schlaile (schlaile), thank you so much for showing me the multicam strip! I never used it before, and it's looks perfect for what I'm doing. And this scene layout is amazing, it'll improve a lot my workflow! Think this could become a new official layout preset.

Right. :-/ If it is not the time calculated, what about use just duplicates amount that will be generated?

@Peter Schlaile (schlaile), the reasons you gave to had not take this bug fixed are very sad to read, and very understandable too.
This disabled slow code can be turned in a python script? - please, say yes...
