Tragic Lantern / Re: Raw video on 50d and 40d
July 15, 2013, 04:28:59 PM
Hi, Sorry to bother, new  - my first post on ML forums...(just started RAW video on my 50d)
I have a 50d like you, its in as new condition... running a Transcend 32gb UDMA7 1000x card...
It seems to be dropping out and stopping after like 200 frames at 1280x720 and even less at the 1472x828 bigger resolution.
Do you have similar issues? Maybe my new card is buggy? or maybe try a better name brand like Lexar etc?
Any tips would be amazing, thank you. I am keen to get it all going smooth as I am ken to then get it set up on a 5dmk2 etc
thanks
toby kazumcihi.

Managed to trade my old 5D for the 50D and cash :)

I got raw recording working. Did a benchmark of Sandisk Extreme Pro 32GB 95MB/s in live view, but it doesn't seem to close the benchmark properly. I can't seem to find a log of bmp of the results. Where should it be?

Maximum seems to be around 50MB/s for continuous recording (with my card).

My results (how can I determine exactly at which frame skipping starts?):
Shot at 24 fps (didn't find a setting for 23.975..)

1592x1062 - frame skipping after about 50 frames (67.7MB/s)
1592x840 - frame skipping after about 480 frames (53.5MB/s)
1592x720 - no frame skipping (44.3MB/s)

1320x1062 - frame skipping after about 300 frames (56.1MB/s)
1320x960 - frame skipping after about 1200 frames (50.7MB/s)
1320x840 - no frame skipping (44.3MB/s)

1280x1062 - frame skipping after about 250 frames (54.4 MB/s)
1280x960 - no frame skipping (49.2MB/s)


The 50D did crash 2 times during my tests. Think it happened just after I pressed recording. Nothing happened, screen would stay on, had to take the battery out.

Big thanks to all of you amazing people making this possible. Shooting raw video on a 5 year old dslr... it's still hard to believe!  ;D
