@JulianH if footage is looking good, we will need a few more 50D testers to review build.
It's looking very promising Gregory, many thanks for the build :) Looking at the files now, I will let you all know soon, everybody is eager, I know ;)

GregoryOfManhattan

if there are other alpha testers interested and standing by with 50D and fast cards, please PM me and i'll arrange to send you a build.

I have a 50d on its way from south korea. It's going to be a long wait (2/3 weeks).
When i'll have it in hands i will of course test new build

Thanks for the test! 

Is the 50D HDMI outputting 480p like the 5D2, 550D, 600D and 60D when recording?  Or does it stay at 1080i when using the RAW recorder?

Recording to H.264 automatically switches HDMI output to 480p but RAW recording DOES NOT - it stays at 1080i. Keep in mind though that the 50D right now does not output the sensor data at 16:9. You will instead get a 4:3 image in the middle with black bars on the side. Depending on the monitor you have, you may have a function to crop the output to 16:9.

New resolution test with GregoryOfManhattan's build, using Hacked mode.

Sandisk 32GB 90MB/s CF

3:2 @ 1592x1062 ~ 135 frames
5:3 @ 1952x955 ~ 270 frames
16:9 @ 1592x 895 ~ 480 frames
1.85:1 @ 1592x860 ~ 850 frames
2:1 @ 1592x796 - No skipping!

It can record over 4GB and span! I shot 1592x796 continously, stopped recording manually at 10GB. The buffer is completely fine. But right now the files don't convert properly so it's not usable yet!

Wanted to try anamorphic resolutions like 1440x1062 and 1320x990 but ran out of batteries...

Overall definitely an improvement over the previous build, that gave me these results:

1592×1062 – frame skipping after about 50 frames
1592×840 – frame skipping after about 480 frames
1592×720 – no frame skipping


JulianH

My quick observations using GregoryOfManhattan's Alpha build:

- Better speed, stable 1592x796 recording (see test above)
- Playback works (B&W, slow speed)
- Buffer improved to 5 stars from 4 stars on my camera
- Way more available resolutions, select width and choose aspect ratio
- 'Digital dolly' mode works!
- Recording with live view button, I don't have to do any kind of work around

- Cropped mode works - display still turns pink but DNG files are fine!
- 4GB+ recording works but the raw files aren't converted properly yet - not usable yet, work in progress
- recording rectable / frame counter is flickering all the time (same as previous build)
- Camera crashes when trying to play back raw files made in cropped mode


I can't recreate the crashes he mentions.

I do not have a 50D to do tests, so I do not know if this resolution is already enabled:

1440 x 810 (16:9) is 49MB/s so probably it would be the maximum resolution for 16:9 in 50D

1360 x 768 is also a good option for 16:9

No need to crop so much. The 50d is fine at 1592 width ;)

1592 Res is fine for me as well..

I am so lucky  ;D: just bought an almost mint 50d for 340 euro including 3 original batteries and original grip. I already have a 64gb 1000x compact flash and some nice m42 takumar lenses so let the fun begin :P

Those advances with Gregory's build are extremely promising, still waiting for my 50D..  When I get it it's on.

Julian - Your 2.5k upscaled still test is pretty impressive. Easily outresolves H.264 1080p. Nice! 8) We'll need a BMCC vs 50d test soon hehe (yes, I know the BMCC will beat it but by how much?)

Nice.. Welcome to the club.  What brand of card do you have?

Wow!!! that is impressive.. love that log look.

I still think the Panasonic GH2/G6 will beat the 50D for detail ;) Have to do that test soon... Dynamic range / noise is another thing.
Got some juice in my battery, did some more speed tests on resolutions that will be appreciated  by anamorphic shooters (like me ;)).

1440x1062 ~ 250 frames
1440x960 ~ 370 frames
1440x864 and lower heights without frame skipping at all

1320x1062 - This is an interesting one, ran it several times and results vary wildly, between 250 and 650 frames!

1320x990 - No frame skipping
This will be my new shooting mode of choice on the 50D for 2x anamorphic. It will output 2640x990 (2.66:1) after desqueezing.

1280x1064 - Looks like it's running without problems, but stopped around the 4GB mark. Might have to test more.
5:4 is pretty cool for 2x anamorphic too, gets you 2560x1064 = 2.40:1

Lower resolution variations like 1280x960 and 1320x880 work fine.

I've got both. How do I get the build you created?

Thanks in advance, Alex

The upscale I did had no sharpening applied either. I'd imagine NeatVideo's sharpening would really enhance the footage.

As far as the log look, it's a must for flexible color. I essentially pulled all of the sliders involving shadow, blacks, highlights, and whites as far out as I could. Saturation reduced as well and exposure brought down to pull the sky back. Grades nicely as well.

Here's the 4k ProRes 4444 of JulianH's footage to play with. Have a go in DaVinci and see the latitude. Way worth the sacrificed resolution.

Yeah you right with a little sharpening from NeatVideo you would be all set.  Your using (ACR) Right.. that's what I've been doing also with the DNG's for that log look than convert to ProRes 4444, but I don't think I would mess around with the exposure if it's already exposed correctly all depends on the shot.  What do instead I would slide the Highlight recovery until the sky has more detail and Voila.

Precisely. The sky here was a bit hot so highlight recovery did quite a bit. I wanted just a bit more detail from the sky so I pulled the exposure down a bit. I can't believe I'm looking at DSLR footage with this much DR

Thanks for posting artiswar.  The saturation slider how far back did you slide it? (-20)

I'm sitting at about -20. -40 is pretty extreme but everything still comes back. Splitting the difference at -30 would be pretty nice.

Additionally, 50D on its way to me. I'll be testing some Zeiss glass to see if that helps with resolution.

Right on looking at the footage you make a lot of sense, pull it back for some more detail.  I can't believe how much DR that camera has, you can pull the sky right back no problem.  Now we can really get creative, and have fun with our grades without worrying about extract noise / Codec breakdowns.  It might have a little less sharpness than the GH2, or G6 but at the end I like that softer image it's looks very filmic.  I have a question you up-res the footage in after effects right.. What dimension did you plug in (4... x 2...)

Same here waiting on mines, yeah Zeiss glasses would definitely help.  But to me the images are lovely the way they are, with a nice grade it will pop, and the edges will be roll-off, and soft.
