I have a request to fix the 4gb limit.
That's no firmware issue. If you want to save bigger files, just format your SD-card as exFat.

Thats great, Thanks a bunch

I didnt know Canon EOS worked with exFAT

Well unlucky would = corrupted FS on card.

Check for sprinkles on this build.. its using 5d3 like correction... someone on 5D2 got magenta cast but I didn't see it.

With defc off I had sprinkles all over. 6D seems unfixable. I'm seeing sprinkles in all types except default.

Run it through eoscard (windows) or macboot.

great improvements in the new build.

1440, 1360 and 1320 16:9 will be very useful for 50D owners, under the 50MB/s limit

loved the new playback features, now I can choose which file to play and can erase files also!

I did try the start delay 2, 4 and 10, but it does not avoid frames skip in 920 x 518.

 the good news is: frames skips in 920 x 518, but there is no magenta frames

768x432 16:9 works ok, no magenta frames in 600D (768 x 512 works also, but 768 x 576 skips)

time to increase it a little bit... I think 816 x 460 16:9 will be a smart try! because it is under the 16MB/s (users are reporting 16MB/s limit is the safe option)

and of course 854 x 480 the perfect option for DVD, we need to try it!

640 x 640 is working ok, wich proves 854 x 480 will work (same datarate)

all my width suggestions: 784, 800, 816, 854, 888

a tip: put the playback above the delete ( the delete the last thing) to avoid pressing delete unwanted.

many thanks

The features in the new build are awesome, but for some reason at 1120x334 (2.39) I can only record 161 frames where as on the last build I was up to 273 pretty consistently, and at 960x342 (2:1) I could record continuously before but I'm stopped at 600 frames now.

try erasing everything on your card, in canon menu: erase files, in ml menu erase the raw files. it helps after instaling a new build.

I did two more tests with 640 x 640. big 2GB files, it is working pretty good, no frames skip, no magenta frames.

this proves 854 x 480 will work good, they are the same datarate MB/s

excited to see 854 x 480 enabled, it will be the best thing for DVD

First post of the thread updated.

The new build is nice, the playback/delete will deff come in handy. 1280x533 over 100 frames, hell yeah. Did a couple quick renders, couldn't see and bad frames, pixels, etc. Auto wb in acr was pretty damn accurate too.

Think I found a bug though, if I have a few raw files and I delete one or two of them, the module stops displaying the rest of the raw files, even after a mode switch. Cutting the cam off and back on makes them reappear.

Great work though, wait till I tell the homies I can shoot sprinkle-free video  8)

Thats just to see your buffers and let go of the camera,etc.

I tried 854 and it was all corrupt, sorry. Also 844... I can try a few more of the others.

Playback hopefully getting to be its own module soon along with file management.

Record twice. That seems to re-do the memory and you can go longer. Second run usually does the trick for me. Buffers are 31, 30, 20something :(

I think 16MB being safe would be on slower cards. I don't hit 21 but I do hit 20 and its fine with LV disabled.

I now have the exFAT working with the new build.

Tested 1136x694 @12FPS and reached 10gb files everytime no frame drops.

All I need now is better write speeds :)

EDIT: tested with Liveview Global Draw and Luma zebras and Luma Histogram. -- works great

Hi 1%

thanks for the answers

please try what you can do to get close to 854, maybe 848, 840, 836, 832... I do not know, but something which can get close to 480 vertical pixels in 16:9

Thanks, latest build is interesting, many new things...

But still aspect ratios on line-skipped modes are calculated wrong:


Why the stretch factor is assumed 1.40x and not the usual 1.66x?

(here's the check pattern: http://www.mediacollege.com/video/test-patterns/images/aspect-ratio-circles-1024x768.jpg )

Thats zoomed or not zoomed 720?

Maybe stretch is different for non digicV or something else?

That's a non-zoomed 1280@50fps. Will try zoomed now...

UPD: So, I did a test. Set the ratio to 1:1, then tried it in different 720p modes - and just looked at the cropmark rectangle (which must be a square @ 1:1 ratio).

1) In non-zoomed 720p mode - the 1:1 square is non-square - it's rectangular - more height, than wide.
2) In 5x zoom mode - the screen becomes BW, and very slow - but the square is now perfect square - ideal 1:1.
3) In 10x zoom mode - the screen is okay again - colored and fast, and the cropmark rectangle again is stretched vertically as in non-zoomed case (1).

Btw, on (2) mode I can visually see picture tearing frames sometimes, during live view.

Didn't do any recordings - guess the cropmarks test should be demonstrative enough.

ML assumes that 720p images should 16:9. Is this not true on 600D?

After formatting and recording a couple times I'm recording as much as previous builds were. Thanks.

Record something at full size (or take a silent pic), then stretch it so it looks normally. Is it 16:9 or something else?

Okay, took it.

The ML tells me it's 1734x694. FastRawViewer tells me the RAW is 1728x694, RawDigger EXIF info tells it's 1888x720.

Here's the silent pic:
https://dl.dropboxusercontent.com/u/9944031/14660049.DNG

Photoshop opened it as 1734x694.

After resizing it to 166.66666% vertically, it became: 1734x1157, and the aspect ratio circle is perfectly right:


So we get 1.4987 aspect ratio, which is very close to 3:2 (1.5)

Zoomed 720p modes (5x and 10x) give me 2520x1080 silent pics with correct proportions and no line-skipping (10x has tearing & pink artifacts sometimes).
Video in these modes is capable also max 2520x1080, and has no line skipping.
