A 7D in its best conditions
« on: July 07, 2018, 01:29:31 PM »
Here we go again!

I again used @wangtrirat workflow to emulate the Arri Alexa look and given the amount of light available in the scene because of the snow, I could catch some of the best rolling shots I've ever had!

I mounted all the clips w/ MLVFS, graded in DaVinci 14, exported the clips to DNxHR 444 10bit, made the edit in Premiere and exported the final edit again to DNxHR 444 10bit.

Everything was shot in 1728x864 at 23,976fps on a 35mm Sigma Art lens, which I adore in combination with my 7D since I only get the best of it due to the crop factor.

I'm a bit disappointed of youtube's compression and I'd really love to get some tips from u guys on how to get the best uploads settings for YT. This time I uploaded the 6gB file in DNxHR but I'm still getting a poor result. I've seen people upscaling it to 4K but isn't there any other workaround ? Please help me guys because my DNxHR file looks way better than the uploaded one and I would love to share it with you.

Those were unfortunatly the last clips I could get before my precious camera got stolen... Hope you guys enjoy it and tell me what you think!


Thanks again to the magic lantern community for being so awesome and making all of this even possible!

Yes, the good old 7D!  No other camera can provide this fantastic filmic look, along with remarkable detail, colors and dynamic range.  Nice illistration of what this camera is up to with Magic Lantern.  It's a pitty you did'n film in 2520x1200 resolution.  The quality would have been even better!  You could have made all processing and editing in Resolve 14 and export in H.264 or MPEG-4 in the original resolution.  This would have given you also a much higher quality after uploading to Youtube. 

As far as your shooting skills are concerned, the video is too shaky and amateurish.  Next time, please use a monopod and practise smooth camera movement.  Also do not pull focus back and forth like crazy.  This doesn't look good.  A LCD viewfinder in combination with a stabilized lens, variable ND filter and some practise will give your video a much more stable and professional look.

Could you please post a link to the workflow that you used to achieve the Arri Alexa look?  Thanks.

Don't upscale, unless it's necessary to fit the specs on the platform you're using. On YouTube, the accepted sizes are always 16:9, on HD, FullHD or UHD standards.
On your case, you uploaded using a aspect ratio of 2.35:1 (1920x818px). You should have made a letterbox to reach the 1920x1080px before uploading.
As about the format, see this here:

I would go for this, but haven't tested yet: 1920x1080px, 24fps, ProRes 444, 10-bit, Rec.2020 and audio using FLAC format (will have to use MKV container).

BTW, @IDA_ML is right about the ND filter. Set to 24fps, 1/48 shutter speed, open the lens and then fix the exposure with a ND. This will give better motion blur and a better "feel"...
A polarizer can help too, to recover some highlights. I heard the B+W circular polarizers are pretty good.

...and a much more boring video! This is exactly the type of videos I'm trying to avoid right there. Gear shouldn't get in the way in my opinion. I'm on vacation with my friend and my purpose is to catch the right moments, not to plan them. They wouldn't have been so comfortable in front of the cam if I'd set all of the stuff up you mentioned. I need to be light and quick. This is exactly what I love about ML, because the result I get right ouf the box is truely amazing as you mentioned and I can bypass all that secondary gear. I used to worry about clean shots, nothing should be shaky, everything in focus, etc... Turned out to be boring. The unperfection makes it in my opinion way more unique in a way.

I admit that some ND would have been suitable in this conditions, but I hate that 1/48 Shutter feeling! I will never shoot under 1/100 unless I need to. However thank you very much for the letterbox hint! I'll try it out next time.

And here's the link to the workflow:
