Canon 5d Mark II - where are the raw video files on the cf card?

[RamGram]

Hi guys, like to thank you about this huge job you are doing with ML in bringing to the world the capacity to evolve greatly in photo, video, time lapse etc...
But, for a native french speaker and a total noob in IT i think your forum is a bit too elitist and very confusing Just saying its very hard for me to find a way here because things arent very well organised in my humble opinion...

Reason why im coming to you with some issues, begging for help
im using the nightly built version of 8oct2014 5d2212.

I was using before an oldest one. With this oldest one, i could perfectly explore on my desktop the cf card to find the files of raw and hdr video for instance. But with this latest version, its now impossible.

i guess im missing a step maybe and i couldnt get the right info on your forum despite having been looking for hours

1) while wanting to change the resolution cant fing the any choise for the height at all and,

2) shooting with a 5dmark 2 and a scan disk extreme card at 120mb/s, just able to record 5s video at around 60mb/s. when the first frame as skipped, the recording stops. if i use the skipping frame option, it keeps on recording but indicates that a lot of frames are skipped

3) After the shooting, cant understand very clearly on to proceed for post processing:
- cant find the raw video files while browsing the cf card via desktop
- how to read the video file before trating it with dng  raw video converter
- could you recommend me a very clear tutorial step by step for beginner

Thank you in advance and keep on doing this good job

1) Height is manipulated via "Aspect ratio".
2) Benchmark your card first. Debug tab -> Benchmarks -> Card R/W benchmark (5 min)
3) Postprocessing is covered here:

unfortunately, benchmarking the card gives no result...still not able to browse the card

[Walter Schulz]

What do you mean by "no result"?
Not running at all?
Or stops during operation?

What do you mean by "not able to browse the card"?
You have a cardreader and there are no files visible in DCIM directory?

[RamGram]

Actually, able to browses the cf card now, but just finding files  with extension .IDX and .MLV for instance:
M05-2319.IDX and M05-2319.MLV

not any .RAW files in the CF Card to send to raw2dng

[Walter Schulz]

This may be (just guessing) because you used MLV recording instead of RAW and RAW processing software may be able to process MLV. Or not.

[RamGram]

Right, i had both raw video and raw video (mlv) set on ON, putting raw video (MLV) on off resolves the stuff and i get now .Raw files
But could you tell me more about the fact that frames are skipping just after 5" of shooting despite using a 100Mb/S extreme card?

[Walter Schulz]

Because recording in both modes at the same time is intended to fail.

MLV is the replacement for RAW. It is a newer and much better file format, and it supports metadata and audio recording. You should use it instead of RAW. You can only use one of them at a time. There are lots of good, easy to use tools for processing MLV:

using a 100Mb/S extreme card?

Capitalization is very important (b = bit, B = byte). 100Mb/s = 12 MB/s. If you meant 100MB/s instead, then it also could be that the card is simply not that fast at writing (advertised speeds on cards are usually only for read speed, and often write speed is significantly slower, you could also have a dud card, this is why you need to benchmark the card). You don't even really have to use the "benchmark" feature, ML tells you the write speed you're currently getting while recording, and if you've already made at least one recording, you'll see the average speed you got at the bottom of the screen when the RAW video resolution option is selected (it also tells you how long you should be able to record at that speed for the selected resolution).
