Hope someone can help me please. I have two video clips overlapping on separate tracks to produce a cross fade. As the first video clip’s fade-out is coming to an end, the clip sudden flashes 1x briefly (or gets brighter briefly) then ends. I noticed it flashes exactly when the next video (in the cross-fade) begins.
I researched the many ways to fix this but the workarounds seem too complex (at least for me). I did experiment with the fade-to-black and fade-from-black parameters located in the fade-in and fade-out effects but no success. I also worked with the suggested ‘Transform’ effect using keyframes and opacity settings but did not have any success.
Just an FYI before proceeding with your request please. I am aware that I have the order of clips in my project timeline moving from lower-left to upper-right in my project. I believe the correct clip orientation should be moving from top left to bottom right? Can it cause any issues with the order I currently have my clips moving on the timeline (bottom-left to top-right)?
I have a crossfade setup on two separate tracks that are overlapping (tracks V11 and V12). The flash occurs as the second clip (in the crossfade) begins. For some reason the flash issue fixed itself however I was able to re-create it again. It has something to do with Transformation effect. I wanted to reduce the brightness of the original clip thus I chose the opacity parameter in the Transformation effect. When I have opacity reduced to anything below 100% it causes the flash. The lower I set the the opacity parameter the brighter the flash. When I have it set to 100% the flash issue is gone. Perhaps I should use a different effect for lowering the brightness but the opacity parameter in the Transformation effect seems to get the brightness level I am seeking.
Although the screenshot shows the opacity setting at 41% I normally have it set higher at about 60%. I purposely lowered it to 41% in the screen recording so the flash is more pronounced. The lower the opacity setting the brighter the flash at the beginning of the next clip.
Also, the two clips in the black and white crossfade were originally in color and I utilized the Saturation effect to make it black and white.
Below is the link to the screen recording showing the Flash issue mentioned above.
What is the Opacity setting for the clip on V12? I’m not seeing any transition or composition between the tracks but a gradual change of brightness (?) in the clip on V11. The flash starts when the clip on V12 comes in. What are the opacity settings there?
Can you please explain where the composition/transition to reverse or invert all tracks is located? I don’t see it in the menu or on the layout. This invert procedure is for all tracks in the project? In other words, using this will invert all tracks in the project that allow the clips (on each track) to move from top-left to bottom-right on the timeline (instead of bottom-left to top-right as shown in the screenshot attached? Thank you.
Where did you get the idea that every transition needs its own new track and that your timeline should look like a graph of CEO salary multiples?
You say you “researched” things, but you surely didn’t learn this from our documentation … did some hilariously stoned AI teach you this?
I’m not even sure where to begin if this is your current understanding of how the timeline works - other than to say you that your best bet probably is to forget everything you currently think you know and start by reading our docs, or watching some good human created tutorials …
The Opacity setting for Track V12 was 41%. It’s only when I have the Opacity parameters set below 100% that the flash occurs. The lower the Opacity value, the brighter the flash. That is why I set both Opacity values to a low 41% to make the flash more visual for trouble shooting purposes. Normally I would have them both set at around 61% but the flash was still visible albeit not as bright. I’ve since switched to using the ‘Brightness effect’ instead of the Transform effect’s Opacity parameter to reduce the clips brightness.
I think I understand what you’re saying. I discovered that after I removed the fade-ins and fade-outs on both clips that the flash was reduced to just a suddden and steady brighter appearance at the start of the 2nd clip until that specific clip ended. This was because the fade-in on the 2nd clip was quickly reducing the sudden brightness issue almost instantaneous at the start of that 2nd clip.
The Opacity setting for both V11 and V12 were the same (41%). Afterwards I set both Opacity parameters (video clips on Tracks V11 and V12) to 100% and the flash was no longer present (with fade-ins and fade-outs enabled on both clips).
Apparently, after removing the fade-ins and fade-outs on both clips I discovered it’s not really a ‘flash’ at all but rather the 1st video clip (in the cross fade) simply gets instantly bright at the start of the second clip (v12)and will remain bright until that 1st clip ends.
As a result to better present the brightness (or ‘flash’ oddity), I made a better screen recording and omitted both Fade-ins and Fade-outs on both video clips to better isolate the issue. Doing so resulted in the 1st clip getting sudenly bright (at the start of the 2nd clip) and remaining the same brightness until the tail end of that 1st clip. Sorry for constantly repeating myself but just wanted to make sure I explained it clearly. See the updated screen recording link below.
Ron, this was my first real rodeo. I eventually learned my mistake but was already way deep into the project to change everything in fear messing up the project. It’s all working fine as is thus I simply continued forward. The project is completed and ready for render (no new tracks). I will not make the same CEO-salary-increase mistake on my next project. Thank you for picking-up on that error.
Sure looks that way, doesn’t it. No, not the result of an AI doc, just my first redeo.
Yes, I’ve been reading your docs, watching scores of Youtube support videos and have learned a significant amount. Step-by-step. Keep up the great work and support. Thank you.
Hmm, have you ever explored same track transitions? I also see lots of clips that are on different tracks but don’t overlap (unless the zoom is so big that an overlap doesn’t show). There is really no need for 21 video tracks unless you want to apply track effects that are all different.
I don’t want to rule out a bug completely, but AFAIK when opacity is set to anything below 100% it means that there is transparency and the pixel values of the images get blended. I don’t know the exact math behind it but believe that the luma values simply get added.
Ok but is this still the case when ‘both’ clips are reduced to the same opacity value which results in both clips having the same (equal) brightness? Thank you.
