550D/T2i raw video recording port official thread

[pavelpp]

Wow, great progress, guys. Going to try this tonight, when I'm back from work!

[Rewind]

I'm able to record 1250 frames with 45MB/s where you can record 1440 frames with 95MB/s, its not a 30 to 50 percent increase

You're right. It was an obsolete information about 30 to 50 percent. New buffering optimizations makes slower cards act better.
Latest tests give me the numbers like this:

Sandisk 45MB/s        Sandisk 95MB/s
450 frames               530 frames

still notable difference in 18%

(1200x496 @23.976 fps)

[rideBMX]

I really don't understand why you all are getting more than 1250 frames, I still can't get more than 800-820 frames and often just 500

Global Draw is off
1280 x 426 (3:1)
1080p mode @ 23.976fps
Sandisk Extreme Pro 45mb/s 16GB

Anyone have an idea?

In this mode 1280x426 (3:1)
With this build i can get 1100-1200 frames with sandisk 45, and 1640-1650 with sandisk 95, so there is again difference in about 50%.
I think there are more things going on besides just writing speeds here.

you're a troll, and I'm not feeding you.

show me a video proof of your claim or stop posting about percentages

a nice educational video for newcomers, but have you ever seen I mentioned extreme pro?? Extreme 45MB/s cards newer than Extreme Pro 45MB/s cards.

Oh, that's clears the air )
I haven't heard of those new sandisks. Will try if i'll find them out there.
By the way, what are the results with these new cards at the same settings? (1280x426 23,976)

[pavelpp]

Guys, I don't know what you did, but with "ML_550D_June_20_2013_Update" I am getting continuous recording in 5x mode at 1344x448 (3:1) and 20fps (Hi Jello setting).

At 21fps >788 frames!

AMAZING!

Some more tests:

1472x490 @18fps = 478 frames
1472x552 @18fps = 178 frames

I am using Toshiba Exceria Type 2 60MB/s card

ML_550D_June_20_2013_Update01 still does not work. Anyone else having this issue?

You must have an old module still on card, best to delete everything and add the update from yesterday

Everything is same in that build except Alex removed debug code and I don't have any issue loading on my card, but now I am using todays build anyway which has more fixes.

avg 1200, mostly 1250

just captured exactly 3210 frames at "23fps"

[Rewind]

my test shows 1715 frames, so 37% increase vs 1250.

Just tried that at 23 fps. Stopped recording manually after 5000 frames.
Do you agree eventually, that pro 95MB/s has better performance, and still may be the reason to pay more for it?

By the way, i've got my 8GB for less then $25 in god damn Russia, i'm pretty sure you can get it even cheaper in US or Europe. So that is not too expensive, right?

I am using Toshiba Exceria Type 2 60MB/s card

anyone using this toshiba Exceria card?
ive been searching and searching till now, this is the best fastest card @lower price i can find.

price: 60mb/s 16gb@54 (in my country)
compared to:
scandisk 30mb/s 16gb@55
scandisk 45mb/s 16gb@88
scandisk 95mb/s 16gb@159

type1 rated @90mb/s
type2 rated@60mb/s
the speed seems legit

[pavelpp]

I formatted the card on a computer, then did low level formatting in camera. Copied all files from the ML_550D_June_20_2013_Update01 folder and prepared a card. Still the same error when loading modules. This can not be a coincidence. I even re-downloaded the archive

UPDATE: Got it working. Not sure what happened.

I noticed that I am getting slightly more frames in 1:1 mode than without it.

I know sandisk extreme cards, been using only on my cameras for last 6 years. but in my country, to get sandisk extreme pro you have pay 2,5x more than sandisk extreme series, for example,

SDHC sandisk extreme 16GB is 36$ (but I can get them at 25$ from a friend)
SDHC sandisk extreme pro 16GB is 83$

I've chosen capacity rather than speed because I don't like to carry my 17,3" laptop with me all time in case of card gets full.

the only thing I'm disagree with you is it doesn't really matter (like %30 to %50) if you put fast card on 550D, it has 21MB/s limit.

i believe the 95mb card will almost write @21mb constantly, so thats why it will record longer.
other slower card will jump up and down around 21mb.

thats what i test all my card with crystalDiskMark.
my slow class6 card even sometime write at 4mb then 11mb

That's exactly what i've been talking earlier and what my tests proves.
Obviously, there is no any reason to buy a card faster than 21MB/s, but what real life tests shows us, is not every card has the speeds manufacturer declares. My idea is to chose the card that is just fast ENOUGH to do the job of 21MB/s.

Sandisk extreme pro 95MB/s does this job. Other cards i have... don't.

Hoping to get a little help from you Adobe Premier users. I am trying to figure out the speed/duration of tiffs brought into Premier. I shot the raw files at 23.976 FPS and I have 472 tiffs. I have divided FPS into 472 and get 19.69. I tried setting speed/duration to 20 but resulting video looks wrong.
Can someone assist?

Try these steps:

- create new bin
- right click bin folder, click import, select all .tif sequence file.
- click bin folder
- click automate to sequence (sequence icon)
- select desired settings, click OK

Interesting. I wish I had found this info when I ordered my new cards. A very small increase in speed makes a difference with the new improvements.

Those of you struggling with getting the higher write speeds with the new hack... Try formatting exfat and post your results

[Kim.dh]

Those of you struggling with getting the higher write speeds with the new hack... Try formatting exfat and post your results

What tool do you use to format, and what allocation unit size do you use?

Same or worse results with exfat

I'm excited that I finally figured out the workflow and programs to get a raw video clip. Here it is

I know its nothing special but it feels pretty good to actually get something done...lol
