Export Settings for Slideshows with Fade

Hi, I do simply YT / Odysee videos which are a series of images faded in over each other. Maybe 10 images in 30 minutes. So it’s a slideshow but with small fading.
What is the best export settings to use so that the files are small but quality good. Previously I found with a 9fps the fades look fine, but with some export settings the filesizes end up being 700Mb. They are 720 in size.
Any expertise on good settings for this case ?

The “Slide Deck (H.264)” and “Slide Deck (HEVC)” presets should work great for this case. They do export a little slower, so they may require patience for longer videos.


Thanks man !

I’m always curious about that preset… how much size reduction did it achieve, if I may ask?

I’ll let you know in the future, currently I am using Openshot for these things but I will migrate over in the future.

From my experience it’s a massive difference, I use it ocassionaly on short screen recordings and I see over 10x decrease in size (also lower quality but I think it’s a decent tradeoff).


Good to know. Thanks
I usually use HandBrake to reduce the weight of a video so it can fit the 8MB limit of the forum. Using this method will save me time.

I wonder though. The Slide Deck (H.264) export preset won’t work on my computer if Use hardware encoder is checked. Do you guys also get this?

Same for me, but I think GPU doesn’t support the settings slide deck needs to compress so much.
In the log I see it complains about veryfast value and Max B-frames 8 exceed 4

(this actually makes sense, CPU has always been better at compressing to the smallest size so it does this by supporting more advanced codec stuff)

Thanks @daniel47 :+1:

Correct. Slide Deck gets its advantages by using settings that are not available in hardware. There used to be a hover tooltip that recommended against using hardware encoding for that reason.
