I want to ask - is this normal in 3x1 mode? (50d) Looks like terrible artifacts...

It's not normal, it's coming becuase of bad configuration . .

Hi all, been getting occasional pink frames when filming with an HDMI monitor plugged in. Any ideas?

hello, i got eos 1200d and i really want go fhd48fps or even 45fps. The problem is that i actually complete nooby in programming etc. Could please someone help me to somehow port crop_rec to this cam? I was looking for it everywhere on forum but there's almost nothing for this camera bout cropping etc. im sending screenshot with error that shows when trying to load crop_rec

Mission impossible.
1200D's SD-card interface is locked at 25 MByte/s and ATM there is no way to tweak it.

Rough calculation (with all the bells and whistles not available for Digic 4):

1920 x 1080 x 45 fps x 10 bit x 0.4 (compression) / 8 = 46.7 MByte/s

Far beyond technical specs for continuous recording.

oh, so that's how it is. so basically the last thing for me to do is wait for someone to break the card write limit on 1200d somehow or just get cash for newer camera. thanks for reply anyway.
Also the continous recording is something that i don't need, if the video recording would be stable for around 2 minutes or so it would be great (it is like this with 1.7x bitrate and it's enough for me)

We are talking about different things.
Bitrate manipulation is for native H.264/MOV recording only and doesn't apply to raw/mlv recording.
Required bandwidth without tweaking is around 5.5 MByte/s. 1.7x should give around 9.4 MByte/s and that's within cam's limits.
