I dunno whats up with this since its working for me like it works for a1ex.

Frame consts are only used on new cameras (those that can do HDR video with shutter timer). The old ones use the slow method, which only change settings via properties or expo override.

I found them all (there are 2 sets, both match, the 2nd iso stops at analog tho), bv seems slightly different than the formula. Is it different on 5D2?

Why can't we use shutter timer? I have it found.

Can anyone tell me when I boot up my camera, I get a scripts "dir missing" message, everything seems to work properly though.

[Frerichs]

Hokie123, I get the same error after I've formatted the card in the camera (ML reinstalls after the in camera format if you followed all the steps found throughout this forum in preparing the CF card.)  I might be wrong, but the simple fix is to drop in a scripts empty folder in the ML directory.

I haven't noticed any issues by having the error to date.

Another 50D RAW video test. This time in B&W.

Shot with 12Jun GregoryOf Manhattan build. I love the possibility to choose different aspect ratio for filming. Thanks to all involve in the development. Vimeo does not show the video in the original aspect ratio, they included it in a 16:9 canvas. 

Great job man.. loving the look 50D is looking more like a champ daily.  Yeah Vimeo I think only does 16:9 aspect ratio. 

[goldenchild9to5]

I just filmed another short test trying to see how do the skin tones look like in RAW, I might add they're pretty good
The only thing I will add is that YT compresses the hell out of the footage, the original ProRes422 file is damn sharp (just a touch of sharpening in CRaw in AE), even the compressed file (h264 15~20Mbps) looks a lot sharper than this, but on YT it looks all mushy.

Great video I think the video is sharp enough, too sharp it would start looking too Videoish...

[John-Jo]

Yeah Vimeo I think only does 16:9 aspect ratio.

Hey just to clarify aspect ratio on Vimeo:
"Can I upload a video with any aspect ratio I want?
Vimeo does its best to accommodate any aspect ratio that you upload. However, there is no guarantee your video will look correct or play properly if you upload an unusual aspect ratio."

Here is one I uploaded at 1:2.35 without back borders (it has no boarders on vimeo and is correct aspect at full screen. It is actting differently here thoguh). Its not the 50D and not raw- its 7D h.264!   - hope no one is upset by that!

EDIT: removed "s" from video link to allow embedding.

Managed to trade my old 5D for the 50D and cash

I am new to ML. Just want to know can u record in desired resolution in ml? or it is having some presets for recording resolutions. Can you record raw in 960x540 (60/30/25/24/23.9p) with high quality ?
Why because as I have seen when we resize image by double it looks better then scaling it disproportional.
you can check this concept with images. I don't know i it same in case of videos. The whole idea is if anyhow we are scaling it because of limitations. why not try low res. high quality video and do other things in post mostly scaling in proportional way.

You can record 960x540 (16:9) at maximum of 30p if you really want to. Higher frame rates are not possible atm.

We will keep this post for general 50D raw video discussion.

I get your point, but I doesn't work like that. More important with downscaling I think.
Try it out yourself, take a random image, resize it to 1584x892 and save. Resize to 960x540 and save as copy. Now open both files and resize to 1920x1080...

[Andy600]

Hmm.. well might want to add the *frame_* stuff to your consts... I don't seem to be having any problem with it locked on iso 3200, it won't even go there, stops at 1600.

Added your Frame stuff to consts.h

Hi! What do you think about Sandisk Extreme 400X 60 MB/s? Who used it? Will it handle 1592×840 24p in 50D?

[icemagic]

resize it to 1584x892 and save. Resize to 960x540 and save as copy. Now open both files and resize to 1920x1080...

As I know Going from 960x540 to 1920x1080 will give better result then Going from 1584x892 to 960x540 and again to 1920x1080. And  1584x892 => 1920x1080 may look different then 960x540 => 1920x1080 but if too much of movement is there then (I think ) 960x540 => 1920x1080 will give better result. Because no matter which interpolation algorithm you use to re-size the video it will just do math. And for computer it is tough to guess which pixel to keep and which pixel to remove (in case of disproportional re-sizing).  I will just do a re-sizing and send the images.  .

If you're looking to buy it I suggest getting the Transcend 600x 16,32 or 64gb which is cheaper and works. I have the 16gb and 1584x950 is no problem. Writes up to 65MB/s.

Alternatively get the Komputerbay 64gb card which is good value for money, even though mine was DOA. Ordered another.

[icemagic]

I get your point,

Just checked. Your work flow is better . Because with image it is not possible to check this.
Only a video will help, which is having same field in both the resolutions. Then only we can compare.

Thanks for the tip! I think, Transcend 600x 16GB is a good choice. What about Transcend 1000x, it's supposed to be faster, but as i know, 50D doesn't support UDMA7 and the real speed would not be so fast?

The 600x card is UDMA7 too. The 50d supports up to UDMA6 so obviously you lose some speed benefits of UDMA7 but it's better to have a faster card than a card that is hitting it's limits.

Re: 1000x transcend. There was some debate on this a few pages ago. On the Transcend website (when you compare 2 cards) it states that the 600x 16gb card (max 90MB/s write) is faster than the 1000x 16gb card (max 70MB/s write) but the 32gb and 64gb 1000x versions are much faster. I haven't tested but I wouldn't risk getting a 1000x 16gb card just to try when the 600x 16gb card works well.

Thank you for advices, really help! I'm getting Transcend 600x 16gb!

Anyone tried Kingston Ultimate 600x 32GB ? The claim is it is 90MB/s write speed, the real life performance is more like 76 MB/s (http://www.gavtrain.com/?p=1831). I wonder how does it fair on 50D? It is on sale now here in Canada (Canada Computers, 60$).


Also - any more information regarding audio support in 50D on a hardware level? I saw it discussed here on page 50, with the statement that 50D seems to have the audio chip. If there is a way to simply solder in an audio in connector (to be used e.g. with Zoom H1 recorder) that would be super sweet.

[JulianH]

I don't think it will be any different with video. It would be easy to try, but I'm not going to do it (sorry). I just don't believe that upscaling something 200% will look better than upscaling something 50%. There is just a lot more detail if you shoot at the highest possible resolution. You're not magically getting that detail back by a 200% upscale.

If there is a way to simply solder in an audio in connector (to be used e.g. with Zoom H1 recorder) that would be super sweet.

Even if that is possible it still has to be implemented in the software...

There is no audio chip inside the 50D.

[ilguercio]

Audio stuff is all in there.. mic is not hooked up.. audio is ak4646. I was going to make it beep next... but battery died. i'll have to use AA's.

720P encoder mode is in there too but not sure if the video mode works... will have to try in C mode.

Don't be fooled by the FW because the 50D has got no audio chip, i pulled it apart until the motherboard and there is no sign of any audio processing stuff.
I know that the FW says you should have an Asahi Kasei chip but i still have my pics uploaded on the CHDK forum and you can clearly see there is nothing useful onboard.

Yea, I don't see one either... maybe can be made to beep through tx19a somehow. Something generates audio to that speaker.

[ilguercio]

I guess so but since it's not coming through the audio chip itself is going to be much harder, i guess.
The 5DII had to be Canon's first Video DSLR; the 50D would have sold a lot more in comparison to the former if it had all the feature they wanted to put into it maybe in the first stages of its development.
The FW is ready for the chip, the body too. Only the motherboard is missing the most important bit.
