Hi All

I´m here writing in behalf of a friend who can´t write in english.
He´s using the 50D night build and recording RAW with a 120mb 800x lexar. with 1568x668 res, 23.976 fps. The record process goes fine with no warning at all but a recorded file of 10 seconds shows only a 7seconds after processing in both raw2dng and MlRawViewer. Also the resulting video is a kind of chunky as you can see here:

Dou you guys think that might be the card used?
Thanks you all

I have found less dropped frames when I switched cards. I cannot say this is the issue, but from experience, I had two komputerbay cards (for example) and one struggled consistently.

If you want to get technical, you can benchmark test the card.

As mentioned above, benchmark the card, also try disabling on screen items such as histogram, peaking, zebra's, or better yet, disable global draw entirely. The right card matters, check the forums for suggestions.

Please tell file size (in Bytes).
Recording was done using which module? RAW_REC.mo, MLV_REC.mo, MLV_Lite.mo?
Give the build date used. Be specific.
Workflow used to convert RAW/MLV?
Can you exclude using crop mode without FPS override?

Thank you so much for your input here.
I´ll pass the infos to my friend and come back with news.

Thank you all :-)

Sorry about the delay, but there are good news.
Using the MlvProducer and a Lexar 1066x card everything went fine. No more droping frames.
That's great.
Thank you all.
