It lives! 5 year old $350 Canon 50D becomes raw cinema monster

[Julian]

The 50D is writing at 70MB/s now with the newest build buy GregoryOfManhattan. 5D3, here we come! ;)

Waiting for my 1000X card...

What meaning does the increase in MB/s to 70 MB/s have if the ~50 MB/s raw is the same resolution? I would have thought raw at a given resolution and framerate would have a set filesize.

[Julian]

With 70MB/s higher resolutions (in crop mode) and framerates are possible.

 

For 1584x892 @ 24 fps (max width in full sensor mode) you need about 57-59MB/s I think. So with 70MB/s you can get higher framerates (30 is max).

 

In 5x crop mode the 50D can go to a maximum resolution of 2000x1080p, and for that you need way more than 70MB/s. As soon as I get my Komputerbay 64GB card I'll test what's the max possible continuous resolution. 1920x720 was already working.

[Tim]

I did a quick test earlier with Gregory's latest build, and I got an average of 69MB/s. One star continuous after initial recording, no dropped frames. Using Komputerbay 64GB 1000X card

[Julian]

What resolution Tim? Can you try how many frames you can get at 1920x1080 in 5x zoom mode for example - and then lower the vertical resolution till you get continuous recording?

[Tim]

It's still locked to 1584x892 and when I zoom in I get around 77 frames before it stops. The screen turns pink when zoomed in too, but I don't believe this affects the recorded image.

[Julian]

Zoom first, then go into the ML menu and you can select the other resolutions. Preview is pink and you don't get what you see (the recorded area is much bigger than the zoomed area you see).

 

I just checked and 2.35:1 @ 2000x852 should be possible (68.1MB/s needed)

Or 2.20:1 @ 1920x872 (66.9MB/s needed)

 

2:1 at 1920x960 would be nice but at 73.7MB/s that is a bit too much currently I suppose.

[Tim]

2.35:1 @ 2000x852 was possible but not continuous. Will try 2nd card soon...

[Tim]

2.35:1 @ 2000x852 was possible but not continuous. Will try 2nd card soon...

Even at 23.976 recording stopped after 30 seconds. 

[Julian]

What card? And how about 1920x872?

With the latest build and a 1000X card 70-73MB/s should be possible.

[Tony Webber]

My 50D test, I'm looking forward to shooting a proper project with it.

Komputerbay 64GB X1000. Haven't speed tested it yet, awaiting USB3 reader.

[Andrew Reid]

I recommend speed testing it in the camera. Magic Lantern has a set of benchmarking tools in the menus. The USB reader isn't as accurate.

[AndyGandy]

Sorry for a stupid question but how you can use Komputerbay's or Lexar's CF cards on 50D? As far as I know 50D have SD card drive only?

[septemberdawn]

The 50D uses CF cards:

I'm currently shooting a short film with the 5DM3 Raw at 1920x1080.  The image is great, but there's just something about the image from my 50D that I love.  I would like to bring the 50D onboard as a 2nd camera, but am concerned about the two resolutions mixing well together.  Do you all think the 50D footage upscaled to 1920x1080 will be consistent with my 5DM3's 1920x1080 footage? 

[Andrew Reid]

Depends on the shot.

 

I wouldn't use the 50D for wides. The lower resolution will show up on those shots, as will aliasing / moire quite often as well.

 

I'd use the 50D for telephoto work especially in crop mode, and as a B cam at fast apertures with a 50mm or longer prime, then it will cut in easily with the 5D3. Image is generally lovely.

[pinger007]

I would love to use it in crop mode for 1080p and for no moire, but two issues...  I can't shoot continuously unless I'm at 1920x818, and it seems like my framing is different when I review it from when I record it in liveview.  Any ideas???

[Andrew Reid]

Make sure you have the ML greyscale preview enabled and it is not set to Canon preview. I'm not sure if it is 100% accurate yet - only just got my 50D. Perhaps Julian will know better. It is still early stages code and large parts of it are experimental so you can't expect perfection. Go with the 5D Mark III if you need no moire - but the 50D is still incredibly capable for the money. Mine cost me 400 euros and the 5D Mark III is 3000.

[Julian]

I'm a bit behind all of the recent developments. Busy with work and other camera's (a new one tomorrow... which I can tell more about on Thursday ;))

 

1080p in crop mode only works with a very experimental build by 1% and with a lot of tweaks as far as I know. Not with the unified one.
