Hey Guys,
so I'm very new to this!
But I'm trying to film in RAW Video (not MLV), and 'Movie recording stopped automagically' comes up 6 seconds into filming, anyone know how i can fix this?
Iv been playing around and have found that if I go into the RAW Videos advanced settings, and tun on frame skipping, i can film for longer, but its skipping so many frames, so i can use the footage!

Any ideas where I'm going wrong?

Thanks Guys :)

Type of cam?
Resolution and frame rate?
File system on card?
Type of card? Benchmark showing which numbers?

edbay

Canon EOS 60D
resolution 1728x972
FPS 25
just realised the SD card I'm using is sandisk extreme 8GB 30MB/s, is that the problem? the card writes too slowly?

Walter Schulz

SD-card limit in 60D: About 21 MByte/s writing to card.
Bandwidth required for 1728x972@25 = 1728 x 972 x 14 x 25 / 8 = 73483200 Byte/s = 70.1 MByte/s

Numbers don't match. See https://github.com/rbrune/mlraw

Im sorry but that makes no sense to me.. Im new to all of this! Im a student who studies Visual Effects, Basically I just want my camera to film as HQ as possible, So I can film on green screen!
What settings should I be using?

Walter Schulz

Maximum storage interface bandwidth your cam is able to handle is 21 MByte/s. The raw mode you are using (determined by resolution and frame rate) requires 70.1 MByte/s.
The numbers don't match.

What is your problem?

edbay

Oh ok, So if i were to get a better SD card that could be written to at 80MPs, would it work?

Walter Schulz

For the third time: The cam's limit (cam = camera) is 21 MByte/s. And there is nothing you can do about it.

edbay

oh okay, i understand, So the maximum my camera can film RAW is 864X486 (16:9) 25FPS. Wouldn't my camera filming normally on 1920x1080 25FPS be higher quality then it filming in RAW then?

Walter Schulz

Apples and pears. Define "quality" first.

Personally, I think RAW shot in 864x486 (can be stretched to 1280x720 if you like) can still look just as good as H264 in 1080p if not better.

I mean see it for yourself as Walter says.

Doesn't hurt to try and experiment.

Plus who doesn't want RAW?
