Deflickering
Hey,
I hope you are well.
Here is a clip I’m trying to deflicker.
I have many clips like that in my 7 minutes reportage.
I thought I had paid 300$ do save myself some time and energy on Davinci Studio but :
https://youtu.be/ZWDvkkZXBbQ?is=PhF8Ecam0GztjBoF
1st clip is the original.
2nd is the clip with the DVR Studio 20 Deflicker on Fluoro Lights.
3rd is the clip with the DVR Studio 20 Deflicker on Advanced Control (Frames Either Side : 5 ; Motion Range : Large)
As you can see, 0 result. Would you have any clue by chance ?
Thank you for the attention,
JeanPS : BM product designer said : « Try rendering the first deflicker and then bring that render back in for a second pass. » If anyone know what that means (I asked, in vain.)

Hey Jean,
That is some serious flickering.
First and Second pass is something I often use for Green Screen keys. But multi-layer the effect instead, and do one render out.
1st fx layer is the main green, 2nd + is for dealing with the variations that did not get taken out by the first key – this is an old way of doing it, but sometimes works.
With regard to DeFlicker, some of the best results I’ve ever had, was through using Re:Vision Effects DeFlicker app. One project was remove a very difficult flicker in the blacks, filmed in a miningshaft, for a feature film that went to 35mm for Cinema distribution.
You can find it here:

DEFlicker is your solution for problematic high frame rate and timelapse footage!

Hey Mads,
I kindly appreciate and thank you for the message.
I’m afraid I would be looking for a cheaper solution if that’s not too naive to ask.

Hey Jean,
That is OK, we all need to work within budget.
I suggest that you give Davinci a go, and follow the advice of making multiple passes on the render (new render for each pass, and then import that to your timeline).
And see where that takes you.
There are other DeFlicker tools out there, some which may be on monthly subscription.
But I still remember when the colourist phoned me and congratulated me sorting the flicker out on the film, with him saying “I never thought that flicker could be fixed” – back in the days of HD-Cam 1920×1080.

PS: Have not dived in to Fusion, yet, but that might have better tools than the Resolve editor has.
Same with the Davinci grading part, where you might be able “Smart Mask” the flicker..? -
Thanks a lot Mads for the shared knowledge and the live human experience, it makes this online place more lively and interesting.
It is very hard for me to understand the advice here because as you know you can either render within the logiciel, either render by exporting the file, which one do you mean here please ?

Hey Jean,
Sharing knowledge is what makes the COW a great place to hang out.
Yes, see each pass as an export out to a video file.
Then import that video file, add the deflicker filter again. If it shows no difference to the flicker with the filter added to the exported file, tweak the settings until you see a change, then export again.
Obviously make sure that use high-quality uncompressed video format for this, or the video will degrade on each export.
Hope this answer your question?

PS: Will be going out shortly, back later. -
You’re the best !
Thank you.
Bonne journée.

Dear experts, here is the result :

I exported the clips on one timeline with the Deflicker effect in Color (to a ProRes HQ file).Brought the exported clip back in the timeline.
Put again the Deflicker effect on it, exported it, and here it is.
