Nice images.  Were you using ML or TL for this?

TL2.0; SixThirty :)

I falled in love watching this photography work. :) please let me know when your film is ready I really wish to see it when is done! :)

about pixel at the edge of the shapes did you have noticed anything at 1408x528 and 960x540? how do you upscale?
for me 960x540 would be useful because reading the clapper boards for taking audio takes several seconds. how do you take audio for sync when you shot at 1408x528 that allow only few seconds of recording video?
my fear (sorry for repeating concepts sometimes I feel like "Sheldon Cooper") is if I show my work to a short film festival in a cinema theater and they see pixels. 

I upscaled using Magic bullet instant HD, it's quite easy to use but I have yet to do some tests between Instant HD and just simple scaling in AE.
The clapperboard is indeed a thing to consider. My short film is meant to be a teaser/trailer to a full short film so it's about 1:30 - 2 min. long which means that we shot everything in one day and there wasn't much that could go wrong. But still, if I really need those seconds I would lower the resolution from 1408x528 to 1344x503 which would give me 2-3 seconds extra.

I don't think you'll need to worry about pixelation. If you shoot RAW 1280x512 or lower, upscale to 720p, not 1080p. That's not necessary. In my case shooting 1408x528 gives me a decent amount of resolution to upscale to 1080p. Also when I import my DNG sequences I first apply a BMD Film LUT which flattens out the footage but also removes any sharpening and denoising, giving me a softer image which results in less aliasing and moire issues. I then use unsharp mask in AE to sharpen it up again.

You can't really go wrong with RAW. The worst thing that could happen is that it looks exactly the same as H264 in terms of sharpness, but it gives you the dynamic range, information to pull back highlights and push colors around to your liking resulting in a much better looking film than H264 could have ever given you. Not to mention that back in the days people shot films on DV cams where you could almost count every pixel during a screening in a festival, but that didn't matter, because what matters is the story you capture. I know it sounds cheezy but I wouldn't worry about pixelation or aliasing.

Here's two frames from the short film I was talking about earlier. First one's the source file (RAW --> raw2cdng.exe). The second one is a processed one, upscaled to 1080p. That's roughly the color palette i'll be using to grade the film. Click on the picture so see the full resolution ones.

Shot at 100ISO, Hanimex 28mm f/2.8 @ f/5.6 or f/8 (can't remember), 1408x528 (2,67:1, max 240-250 frames)



I think it looks great and the image upscales very well. But I have no shame in admitting my cinescope fetish and I love these widescreen images, which allow me to record longer at higher resolutions. Now obviously that's not always an option. The higher the aspect ratio the lower resolution you're gonna need to use.

Thank you MrMehh, I was looking here for an answer very often since I asked my question. I really wish to say thanks to your help. Could I ask you some general advice/tips on the 600D raw shooting please? and which sd card do you use?
no aliasing and moire were obtained shooting at 5x? or with which camera settings?

thanks a lot again! have a good day! :)

I used SanDisk Extreme SDHC 45mb/s cards, 16GB & 32GB. The 90mb/s cards don't make a difference because of the internal write limit of 20mb/s, although it will help copying the files from the card onto the computer via internal card reader or USB3/thunderbolt readers. But I wouldn't go below 45mb/s either just to be sure.

Some tips would be to prepare yourself, know the ins and outs of using RAW, what settings you use, etc. What I tend to do is use ND-filters so I can open up my lenses all the way which purposefully creates a softer image (depending on the quality of lenses you use, I use vintage lenses) which will help a little in getting rid of moire and aliasing. Just as with H264, the lower the ISO, the cleaner, sharper and better your image will look. Also make sure you've got the knowledge and experience of handling the post process (conversion, proxies, grading, editing).
I convert using raw2cdng, note the c which stands for CinemaDNG. Those work natively with DaVinci Resolve which you can use to grade and create proxies. The latest version of Resolve doesn't have any issues with pink dots or dead pixels anymore. My footage looks absolutely wonderful in it. If you have any more questions, feel free to ask :) Maybe other people can learn a thing or two as well.

Settings I used:

Audio OFF (We used a Zoom H4n for external audio)
Canon menu --> Video mode --> 640x480 (30p)
FPS override to 23.976 fps
Global Draw OFF (no ML histrograms, camera settings, waveforms, focus peaking or zebras, etc)
RAW Video: 1408x528 (2,67:1), buffer warm-up 32mb, no extra hacks, canon preview mode (~240-250 frames)

What I also found was that oddly enough official Canon batteries work better. The first part of the shoot I used my original battery which gave me the full 10 seconds I needed but in the middle I changed battery to a cheaper alternative and it all of a sudden couldn't record longer than 100 frames. I don't know if that was my fault or it not being warmed up or just coincidence, but I grabbed the official battery from our BTS camera.

are pink dots (or other glitch) often spotted on 600D? I mean how often do they appear? I wish to shoot a short movie with 600D raw, could it be possible? thx A LOT ( :) )!

I personally haven't experienced it a lot, not at all in fact. I recently shot a post-apocalyptic short film in 1408x528 RAW on the 600D and out of the 70 or so shots there was one shot that had a pink first frame, which is easily removed since the clapboard was in the frame so I didn't even need it. I had no aliasing or moire issues either. You have to practice using RAW a lot, test a lot of footage, test your lenses, test what duration works for you, test magic lantern settings, test ISO's, etc.

Not yet, I didn't use a tripod so it's gonna be a little shakey. I thought the frames would suffise, but i'll render and upload it to Vimeo tomorrow. (I'll edit this post, with video)


Here's the video!

Don't know how to embed, so click here!

I actually got the latest ML version, SixThirty and was happily suprised that I could use even higher resolutions for about 10 seconds.
Same settings as I stated before. All frames are captured from a 10 second 23,980 (FPS override) recording.

Canon 600D/T3i, Helios 58mm f/2.0.

1344x576 (2,35:1), 10 seconds, ungraded (straight from camera)

On my camera I got 1280x544 (2,35:1) at 23,980 fps for 240 frames (10 seconds), or 1344x512 (2,67:1) at 23,980 fps for 240 frames (10 seconds). I should also mention that this is not on the latest build (CurrentHack). All in SRAW mode, 480p video mode, GD off, etc.

I can relate to most of the things you stated. I personally haven't done any denoising to my footage yet because I like to use FilmConvert over my footage and to remove the monochromatic grain/noise and add filmgrain back in later will give me, for as far as I know, a slightly softer image then just leaving it as it was. The biggest thing I noticed between, let's say the 5D MKIII, and the T3i is that the 5D looks almost like an Epic at 1080p but the T3i looks more like 16mm film. The 5D's image is just stunningly clean. I haven't seen that yet on the T3i.

I recently shot my vacation for a filmcontest in RAW and because I didn't really need shots longer than 30 seconds I shot everying in 1216x512 (2,35:1) to give me just a bit more resolution, and later upscale to 1280x539 for YouTube. I could shoot for up to max 40-45 seconds at that resolution, which was more than enough. I used Sandisk 32GB & 16GB 45mb/s cards, maybe something you should look into, especially if you upscale to 1080p.

Hope to see some denoised RAW frames soon, really curious.

Hey guys, i've been following the progress for a while now and i'm not technical enough to join some of the conversations going on here so I mostly read, learn and test.

Today I did some testing and I got some decent results..

~900 frames (~38 sec.) at 1216x480 (2:67:1), 640x480 mode, FPS override to 23.980, Dont click me hack, Sandisk 16GB Class 10 45mb/s. And ~550 frames at 1216x512 (2:39:1), same settings.

All in SRAW, btw.

I think we're definitely getting somewhere now.
