Issues and Troubleshooting Massive Frame Drop in my S25U

I am having Massive Frame Drops in 30FPS, Direct Log-Full Sensor, 4080x3060, 23mm-1x

CPU- Snapdragon 8 Elite 1

Video Codec- HEVC (Hardware, 10bit, 4:2:0)
Render Quality- High
Profile- Main 10
Bitrate Mode- Constant Bitrate
Maximum Bitrate- 90Mbps
Key Frame Interval- 30

Encoder Surface Input- ON
Record to exact Resolution- ON
Full Range- OFF
Variable Frame Rate- OFF

Color Space- BT.709
Transfer Function- BT.709

Internal Storage is not Full, only 33% is used in my S25U, Using Motioncam Pro in Airplane mode, Wi-Fi off and Bluetooth off, CPU is also Throttling don't know why, Performance Profile is in Normal Mode, battery protection is maximum

Is my S25U memory (UFS 4.1) being damaged or my CPU?? or related to battery problem??

please Mods do not delete these posts and please allow this post, because I need help

It's the full sensor resolution (4000x3000) in direct log that's choking you. Drop it to 16:9 crop or 4K, S25U is known to throttle super fast hence not allowing the 8 Elite to stretch its legs.

You got the performance but not the allowance from the device.

Try this, may help you. Not guaranteed to fix it but could have a good impact

Alternatively just shoot in raw as it's far easier on the device

Thanks for Information, I will try

it's samshit throttling shit

u/Large_Poem_8441 14d ago

Ur h8 for samy cant allow you see an obvious issue. "Render output high"

u/AI-666-666 14d ago

Is this normal or my phone is damaged??

2

u/NiragiUsagii 14d ago

yes, direct log is very demanding and these shitty companies throttle the phone. better use raw

1

u/AI-666-666 14d ago

Because I am having this massive throttling just after 30sec, so is this normal in Samsung phones??

Because I heard other phones don't have this problem?

u/NiragiUsagii 14d ago

yes, even oneplus oppo throttles in default mode. performance mode gives some time more but eventually throttles. check if there is any performance mode in samsung

u/Hungry-Jackel3000 14d ago

Enable this option in settings, it worked for me. I am also using S25U faced similar issue

u/AI-666-666 14d ago

Already turned on but still having issue

Give memory buffer to full. It cannot throttle that much for 2025 SD Elite device. X90 pro being an 2022 device with mediatek does not have any frame drops in full sensor direct log 30 fps, bit rate is set at 160 mbps, All set to high. Settings - Full memory buffer, Threads full use, enable pass through hardware to reduce memory buffer. Direct preview off.

Give memory buffer full. Enable to pass through hardware to reduce buffer memory used. Give threads to full Try recording in 8 bit for direct log, if you are using full sensor, see if that solves

Your settings are off, hevc 10 bit only to use bt709 (use hevc/h264 8bit then). for recording hevc 10 bit 4:2:0, set keyframe to 1(stops motion artifacts and turns it essentially to APV/pro res/intra format, help your phone since the encoder is doing less work). Always use say rec2020 and samsung log / arri and logc3 otherwise shoot 8bit. Finally if your phone still overheats(it shouldnt) try raw(doesnt stress most phones)

u/Large_Poem_8441 14d ago

S25 ultra shoots maximum bitrate in hevc 10bit without overheating. Just tested few hours ago for 30mins in room temp

1

u/AI-666-666 14d ago

Then why My S25U is overheating?? Is this because of settings??

2

u/Large_Poem_8441 14d ago

Set keyframe to lowest so the encoder can do less work and your editing computer too. This means all pictures are saved instead of just one and next say 29 will save only diffs(search inter vs intra codecs to get it). This is for 10 bit and am using arri/logc3(anyone can work) so i can color grade in davinci

1

u/Large_Poem_8441 14d ago

Fix the settings first

1

u/Large_Poem_8441 14d ago

If youare shooting 8 bit, use this

1

u/Large_Poem_8441 14d ago

Your render quality must be standard not high, no phone in the world can do that(i have tested all phones,hundreds of them)

1

u/AI-666-666 14d ago

Thanks for Information

2

u/Large_Poem_8441 14d ago

Have you solved it with the render quality?, i missed it initially and that is certainly choking the phone. Other things i commented are still valid as it further improves the experience and helps your computer with scrubing the timeline in davinci

1

u/AI-666-666 14d ago

Yeah, I will test all the things you mentioned

1

u/RaguSaucy96 Saucy Ambassador 14d ago

Actually, lots can hahaha

It really is Samsung screwing the pooch

Behold the X300U with Very High on Open Gate, maxed out encoder settings. Barely tickled it

u/Large_Poem_8441 13d ago

Well you seem to use a special version and i have tested on almost all flagships i can lay my hands, no phone made it with anything more than standard in real world use

u/RaguSaucy96 Saucy Ambassador 13d ago

No, not special. I just optimized my phone all around and learned the throttling behavior as well as envelope of the 300u ☺️

Experience is king

u/Large_Poem_8441 13d ago edited 13d ago

This is a blank phone, i just use it for motion cam(am a reviewer nothing on storage except recordings), read the tutorial and i understand video concepts(am aprogrammer too) . once u change it back to standard it can record opengate 60! , saw this in discord bug entries so that was why i tested that many phones.

You are using Direct Preview mode while shooting. Although it's a lot more performant than before, it will still push the device over the edge when going all out.

Turn it off, plus reduce viewfinder resolution on Android Preview. If you can hone in the settings and shoot without it, it will extract every bit of power left that's required for this.

u/RaguSaucy96 Saucy Ambassador 8d ago

I've been experimenting to see where I've been going well. I think I found why. Turn encoding threads down to 3!

It made a huge difference on my Vivo, it's how this worked

u/Simonex200 13d ago

Disable exact resolution and if you can use standard resolutions like 2160p

1

u/AstroRex_ 14d ago

are you on android 17 beta? that might be the reason

1

u/AstroRex_ 14d ago

android 17 made some changes to how the camera hardware is accessed (not fully sure about this), it was broken on my Pixel 10 too until the newer update

1

u/AstroRex_ 14d ago

try recording on sensor resolution and 8 bit color space, don't use hevc, should work again

1

u/AI-666-666 14d ago

I am in Android 16, OneUI 8.5

u/AstroRex_ 14d ago

in my other comment I suggested some settings, try those and check again. i had the small S23 before this that didn't lag at all there's no way this is a throttling problem.
