Why i can't get my YI to record stable at 45/50mbps??

[Lorenzo88]

Hello guys,

I've been trying lots of times to record videos at those bitrates but i can't get the camera to record a single video file.

If i record at 40mbps all goes smooth no problems but as soon as i set 45 or 50 mbps the video file starts to slit up in 2 , 3 or more bits each one with different bitrates Eg. 1st file 45mbps 2nd file 37mbps then 25mbps and so on....

Whats going on? I've always used the fastest memory cards on the market (sandisk extreme) and today i've got a Samsung PRO 32gb read 90MB/s write 80MB/s but the issue persists.

Also this is the script that i use on FW 1.2.12

#vibrance/saturation adjustments
t ia2 -adj ev 0 0 140 0 0 150 0

#shadow/highlight clipping adjustments
#this makes blacks not crushed
t ia2 -adj l_expo 163

#fullHD 60 fps 40 Mbps
#writew 0xC05C1EE2 0x4220

#fullHD 60 fps 45 Mbps
#writew 0xC05C1EE2 0x4234

#fullHD 60 fps 50 Mbps
#writew 0xC05C1EE2 0x4248

#4GB no split files
writew 0xC03A8620 0x2004

#disable sharpening
#t is2 -shp mode 0
#t is2 -shp cor d:\coring.txt

#de-noise values between 0-16383 (0x0000-0x3FFF)
t ia2 -adj tidx -1 1500 -1


what am i doing wrong??

SD can probably not with that speed bitrate

SD can probably not with that speed bitrate

i didn't quiet get what you wrote!

Can you elaborate?

Are you joking?

The Samsung PRO is one of the fastest SD memory card you can get!

No bromeo
Indico una posibilidad frecuente sin saber la SD utilizada.
En mi caso utilizo Samsung evo 64 grabando a 45 MB sin problemas

I am not kidding
Indian frequent possibility without knowing the SD used.
In my case I use Samsung evo 64 recording 45 MB without problems

did you read my first post? i am using a samsung PRO sd card which is one of the fastest on the market

leíste mi primer post? Estoy utilizando una tarjeta SD PRO samsung que es uno de los más rápidos en el mercado

No digo que sea mala tu tarjeta, pero:
- La Yi no funcione a altas velocidades con un modelo concreto de tarjeta.
- Esté defectuosa.
- Sea una falsificación.
Yo tengo una samsun evo naranja de 32 y otra de 64, en teoría iguales, pero la de 64 es más rápida.
Yo intentaría que hacer pruebas con otra SD para salir de dudas.

Not saying it's bad your card, but:
- I do not work at high speeds with a particular model of card.
- Be faulty.
- Be a fake.
I have a evo orange Samsun 32 and a 64, in theory equal, but 64 is faster.
I try to do another test SD to be sure.
