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 ?
Thanks
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.

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)

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.
