Update instructions

Note: The following settings have been updated, thus their changes saved using previous firmware versions are not loaded from existing profiles:

* A-LM 288p proc (due to new presets)
* Audio options (due to new mono ADC option)
* Extra AV out mode (due to new output modes)
* Legacy AV options (due to range fix)
* Csync combiner (due to new default value)

Hi marqs,

I’m using OSSC Pro (fw 0.82) with 480i sources in scaler mode at ×2 Hz (120 Hz output). I noticed that your implementation of BFI for interlaced sources does not produce visible flicker, even though BFI is active. I’d like to ask a few clarifications:

How is BFI implemented for 480i @ ×2 Hz internally?
Specifically:

After how many source frames do you insert the black frame?
Is it 1 frame on / 1 frame black, or a different cadence for interlaced?

When I enable BFI, the image does not look darker at all.
On my display (LCD/OLED), typical BFI clearly reduces brightness, but here it’s almost unnoticeable.

Is this expected with your interlaced BFI logic?
Could it be because BFI is applied only to certain fields or blended in a way that reduces flicker without heavy dimming?

How can I verify that BFI is actually active?
Are there any telltale signs (e.g., flicker pattern, motion clarity, brightness behavior, or an internal counter/LED indicator) I can use to confirm BFI is working as intended?

Stunning Update… wow… very impressive! Thank you!
I also have a new idea for line-dropping… in this version, you can only 480p content convert in lm-a to 720 x 480i… so of course i set my emulating mini pc to 720 x 480p…. there is possible to doesn’t fix the horizontal “cols” and send only 480i like 240p mode … so i can send a “genuine” 640 x 480p to my ossc pro?!
This would be very nice, but it’s not a duty, i have yet a very brilliant picture!

@vess: BFI operates on frames of deinterlaced 480i so the end result should have same amount of dim/flicker as with equivalent 480p source. You can control the insertion ratio with “BFI for duplicated frames” setting, but obviously going beyond 1 only works for 180Hz, 240Hz etc. output.
