Raw Video / Re: RAW on 650D / 700D?

« on: June 01, 2013, 04:16:54 PM »

1280x560 is maximum i could get on my 650D with UHS-I card. It seems that controller is limited to 30-40mb/s which is poor
but 1280x560 looks great, even upscaled !

This is so awesome to play with!

I have a Mark II, and a Transcend 400x 32GB card. When I run the benchmarks, my write speed is around 37.5-50MB/s, only at 16384k buffer is it under 40, and with the rest it's usually closer to 50. Read speeds are around 65MB/s consistently.

The anomaly is at 128k buffer it's only 25.5MB/s write speed

I'm trying to record at 1280x720 at 24fps, and it says i only need 36.9MB/s to record, however, I only get a few seconds before it starts skipping bad and automatically stops.

Even at 1280 x 540, which says it only requires 27.6MB/s it starts skipping within 10 seconds.

I can record without skipping at 960 x 540, but I still get a lot of magenta blocking.

I tried with both the May 14, and May 16 nightly builds and the 5D Mark II record module and autoexec.bin that someone else posted.

Is there something I'm missing, or is this normal?

global draw off, and also set FPS override to 24

Suddenly the 650d looks like a winner based on those card benchmarks (and there are even faster UHS-I cards out there). That will be the BMCC pocket killer... eventually


@Vitos1k - can you run the card benchmarks again with global draw OFF and post the results?

Second test, with GLOBAL DRAW OFF



not much of a difference. But still 37.9MB/s

hm, using simple math i found that i could handle 1280x720 with 37.9 MB/s writing speed
Cool! Waiting for 650D RAW footage implementation

Quick test with the 600D. I get files 1280x540, but with macroblocks magenta (from time to time), perhaps due to my card "super-slow".
Processing was nil in both sequence (H.264 and RAW).

How fast benchmark was for you? I've got 650D and SDHC 32GB Class 10 UHS-I Transcend TS32GSDHC10U1
and benchmark gives me speed up to 37.9mb/s
i was wondering, which resolution i could handle with RAW recording?!

?!

All 500D testers said it's not working; some of them got it to work when holding the AF button pressed, but not always.

It was working in early 2012. Was checking it few times! And also there are youtube HDR videos with 500D + Magic Lantern
