is anyone experiencing black holes when recording RAW video? It seems like a bug from the latest build
Do you have a sample or picture showing the problem? which build exactly is affected? and is there a previous build doesn't have this problem, which one?
Hello, i have just installed the ML nightly build for my 1200D and i was wondering if someone could help me and advise me on if there is a way i can record RAW on the camera at 10bit instead of 14bit. I try to record 14bit and set my CBR to 0.5x however after 72 frames, it stops recording.
Could someone explain if there's a chance to record RAW on the 1200D for video and if so, how?
Is it hardware limited due to the fact it's an old camera or is it restricted due to limitations of my SD card?
I am not as technical as most on this forum but i am willing to learn.
Kind Regards
Hello
CBR doesn't affect RAW video in any way, it's just for H.264 video recording. Nightly Builds don't contain 12/10-bit options for any camera. There are experimental builds in the
experiments page which contain builds for 10/12 bit for some models, unfortunately and currently there is no build for 1200D with 10/12 bit-depths function.
1200D has limited write speed, mostly it is 21 MB/s as many DIGIC 4 cameras, overclocking is a solution for this case, but also currently there is no overclock for DIGIC 4 cameras to bypass this limit to achieve more write speed, this is the main reason for limited recording time, other ones might be from your SD card, you can run card benchmarks using Bench.mo module directly from the camera and see how the card performs,
Also uncompressed 14-bit recording is a lot of data at maximum RAW resolution in 1200D for a such limited write speed, a workaround for this is to get 14-bit lossless compression working on DIGIC 4 cameras, this could cut the required writing speed by half by compressing the RAW data losslessly @ 14-bit.
For now you can only lower the resolution for continuous recording.
