5D3: 1.1.3 vs 1.2.3 Slow Mo Record Times

[spnsir]

Hey all,

Just for reference. Here's an unscientific look at how many seconds I can record for:

As you can see, 1.1.3 has a very slight edge on 1.2.3 at 60fps, and at 50fps it is a significant difference. Based on prior tests I can record for 2.5 minutes at 50fps on 1.1.3 MLV. All settings were optimal settings with the same GD options turned on for both (cropmarks, raw zebras-off while recording). All shot on a Kb 1066x 64GB card.

Interesting..

Out of interest (and if you can be arsed to check) what do you get on 1.1.3 at 50p with a 16:9 ratio?

i also find that version 1.1.3 is faster... i am still using nightly from 10th august. Still the fastest for me with no bugs at all.

If I recall correctly, I get about 9 seconds at that ratio at 50p. At 60p I get 4 seconds.

What bugs did you find on 1.2.3, that are not present in 1.1.3?

[Walter Schulz]

He said he found no bugs in this 1.1.3 build (10.Aug.2014). Speed is his main concern, I think. And I would not expect anyone claiming to use an rather old build to say something about bugs in a version he/she is not using.
Come on, a1ex ...

Have you been able to reproduce anything about existing/nonexisting speed differences between 1.1.3 and 1.2.3?

[a1ex]

He said it's faster than 1.2.3 (he was comparing the two versions).

[Walter Schulz]

Spnsir came up with numbers.
Would it be of any use to do some tests with a newer 1.2.3 build? If he wants and has time, of course.

Have no 5D3 at hand, sorry.

[a1ex]

No, the build versions are OK.

The slowdown might be from the dual monitor support code (LiveView is quad-buffered in 1.2.3, even on built-in LCD, but 1.1.3 is triple-buffered).

[spnsir]

Would it be of any use to do some tests with a newer 1.2.3 build?

That is the newest 1.2.3 nightly

[Walter Schulz]

Sorry, of course you're right. Forgot 5D3 1.2.3 has a very different schedule compared to the rest of the bunch. Sticks out here:

If I recall correctly, I get about 9 seconds at that ratio at 50p. At 60p I get 4 seconds.

Nice. I consistently get 6 or occasionally 7 seconds on 1.2.3

[legreve]

I concur... the 1.23 builds are pretty much useless in terms of 50/60 fps....

Last year I made a music video that was shot entirely in 50fps 1920 with 1.85 aspect, and there was zero issues with continous recording.

I tried just today with the 1.23 and a march 17 2014 build and I couldn't get past 6 seconds.

So... I guess I have to go back to the old firmware.

hi all
i get continuous 50p with the 24 jan version 1.1.3 - 32 gb san disk 160mb/s
nothing since can record more than 2 min (1.2.3 a lot less)
just one bug - if you run out of cf card, the last mlv file will NOT be saved)
hope this helps

Thanks @Audionut -- Benchmark speed test with new KB 128gb 1066x...

1.1.3


1.2.3


Chime in your thoughts regarding this particular KB card -- is it worth to keep?

[a1ex]

To double-check, can you run the same test in playback mode, with the same card, on both 1.1.3 and 1.2.3?

And while you are at it, can you also run the benchmark in the 30p and 50/60p modes? (on both firmware versions)

[DeafEyeJedi]

sure will do @a1ex...If I understand correctly for the playback mode -- is this the one that you watch RAW/MLV files on the live view or you meant that for something else?   

[a1ex]

Much better to use the one where you watch still photos, not videos.

[DeafEyeJedi]

currently BM'ing them per your request -- still unable to put it into 'playback mode' so could you try to be a bit more detailed on that one if possible?

thx

**EDIT**

My fault I think what you meant was for me to have LiveView enabled under Global Draw which states in 'Playback mode' is this correct?

[a1ex]

How do you call this button?

[DeafEyeJedi]

bro I knew that was the button for playback mode but I guess my question was how to actually BM during playback mode only because when I try going back into ML menus by pressing the 'trash button' it asks me to delete picture/video or not...

sorry to be such a foolish nut in here but willingly to help. my apologies, Alex.

**EDIT**

Actually I just randomly decided to press playback right the second after I start the BM process... was this what you were referring to this whole time?

because there was the playback mode in the background...

[DeafEyeJedi]

and I wonder why the write/read speed is SIGNIFICANTLY different!!!

I mean holy smokes...

but then how come we don't get these massive numbers for RAW/MLV shooting?

[Audionut]

IIRC, CPU cycles are needed for data throughput.

Playback mode doesn't require many CPU cycles, raw recording does.  More CPU for raw recording, less CPU available for data throughput.

[DeafEyeJedi]

Thanks @Audionut -- that makes sense. However, I'm still worried that I may have gotten a cheesy version of KB 128gb 1066x in my hands...

Here's the BM comparisons re: KB 128gb 1066x per @a1ex's request (THANKS for clarifying the Playback mode trouble that I was having earlier):

1.1.3 (Playback mode)


1.1.3 (24p)


1.1.3 (30p)


1.1.3 (50p)


1.1.3 (60p)


____________________________________________________________________________________________

1.2.3 (Playback Mode)


1.2.3 (24p)


1.2.3 (30p)


1.2.3 (50p)


1.2.3 (60p)


Obviously RAW/MLV write speeds are slightly over the edge in 1.1.3... my question is do you guys think I should keep this KB 128gb 1066x card?

Thanks again everyone!

[DeafEyeJedi]

Well guys I think I have some interesting news (whether its good or bad) but I decided to run a test to see how long I can record MLV in 23.97p 1080p (MLV Audio ON) for....

I got slightly just over 24 minutes of continuous recording until the 'eXfat Full' pop-up window which indicates that I've ran out of space as to be expected.




Guess I should be OK about keeping the KB 128gb 1066x card... right?

**especially after the fact that I actually enabled an option in ML menu to 'save reserved space' to prevent loss of footage once the card fills up. LOVE it!

**EDIT**

Next test will be 30p & 50p/60p continuous recording times w this same KB card...
