Let's Fix It! | Banding in Your Render!

- Let's take a crack at fixing color banding which often occurs with clean footage when rendering to an HD or even 4K master. Here we use a quick & easy industry standard technique... dithering using grain overlays.
Please be sure to follow along with your own footage. The results can be hard to see on RUclips, but it does work! Please be sure you are viewing in 1440p or higher quality in order to better view the demonstration.
Due to RUclips compression, even 1080p will simply not show the results properly... which is at least a demonstration of RUclips's inability to retain detail in HD.

To sort out comments about not seeing a difference... please pay attention to the first slide which says to please watch in 1440p+ in order to better view the before/afters. Its hard to show this kind of result on RUclips due to its compression. As with all my tutorials, I intend you to follow along with your own shots to see if it works for you.
A fix for RUclips compression this is not, but it is helpful for other deliverables.
Love how youtube just ass blasts the footage so before and after look identical
Yeah it's really annoying. Did everything I could to show it but below FHD it's just crap
Very nice, I didn't know this was an industry standard solution! Thank you!
Such a simple fix but very effective! Totally fixed the banding issue I was getting while adding lens flare overlays and lighting composites. Thanks!
Tony Dae is cool. He knows his shit and explains that shit in a no-nonsense manner. Thumbs up, man.
Bro thank you so much! This was so helpful. I was doing export after export trying to figure out how to fix the banding issue.
Thank you!

Oh great! Yeah I pushed 8bit footage a bit too far, this made a huge improvement, cheers!
SUPERB! Saved my day, trying exactly to remove these circles, which appeared after applying the tilt/shift effect. Thanks a lot for sharing your knowledge!
thanks a lot for this
ahh man this is litterally what i needed
That's really cool. Did not know before watching!
Tremendous tip, works like a charm! Thanks a lot!
0:14 “after” * looks worse * 😂
Fantastic video. Thanks, Tony!
Invaluable information as usual. Thanks, Tony.
thank u
film grain is limited to the paid version :/
@manuvlad there are grain packs you can download. Use these in the same way and you should get the same results.
I can confirm, I don't have the full version, I used a 35mm film grain overlay video and used the overlay blend method with the film grain added over the other clips in my project and it works really well! Also, I didn't have to pay for it, it was from a free pack found online. @@TonyDae
what nice trick :)
oldie but a goodie
Great info!🙌
I sure wish I could have no banding in something that was lower res...
FANTASÍA!!!!
Great!
Now make sense that after using Picture clarity settings (which includes noise reduction ). in my QLED TV ( wich most if the TV "calibrators" tell you to turn off on your TV) I got rid of all banding in RUclips videos and my panel runs amazing now.
im getting same fail at glow effect, now i can fix it...
There you go. way more professional my friend
Really helped, thanks !
You're welcome!
I think this is happening in a blender video render can I show you to confirm?
Does this help for the windows update 😔
Thanks for all the tips! For me there seems to be another issue, where no banding occurs in resolve, but when I export, I do get a lot of banding. Any idea how to solve that?
This is difficult to address because it could be one of many issues. Usually the downres from high pixel count (4k) to standard deliverable (HD) is the culprit and this can only really be fixed by adding grain on an hd timeline instead of 4k timeline. More pixels means smoother gradients.
Another is compressing from 10bit or higher bit depths to 8bit deliverables. Again, adding grain helps to dither the banding that will happen naturally due to less samples of color for gradients.
Lastly, check your compression settings for delivery. Use Nvidia if possible as it's better than native for 8bit compression and choose higher quality/ more mbps. See if that helps.
Last point is that if you intend to publish to RUclips, the added compression will cause banding regardless so don't worry about it too much if RUclips is the destination.
I tend to get a lot of banding with gameplay footage; it looks fine in the original and in the viewport, but when it renders, it gets these weird lines where the character's moving, almost like it's not reading the motion blur correctly. Do you have any tips for that?
It's probably your render settings not having enough data allocated or you're going from a ten bit source to eight bit source. For game footage with lots of detail in grass and all that it tends to artifact when you move the camera but looks fine after. If this isn't happening in the capture, you may need to increase the bit rate for the render. On RUclips playback though it's likely going to smear those details anyways. I'd have to see the source and resulting render to provide a better diagnosis.
@@TonyDae I looked at some more articles and found out my issue wasn't banding, it was actually artifacting - - whoops! But I got better results when I switched my format to QuickTime via the H.265 codec. MP4 files really don't like me, it seems lol
I thought the issue would be artifacts based on your explanation. Glad you got it sorted! 😁
@@TonyDae the encoding still screws with the color balance from the original footage I imported (i.e. dark colors are like 5 shades darker), but the quality's more consistent :) Would a re-encode in Handbrake fix the issue while keeping the same quality?
(Sorry for all the questions lol)
Could be a tag identification issue. Check the color space and gamma settings in the delivery/render page. Have both color space and gamma set to rec709, then render. See if that fixes the issues.
