No probs... definitely a case of try before you buy, for your needs.... i think the live view issues will be a nightmare, underwater.

kidfob Posted July 10, 2017 Share Posted July 10, 2017 Jimmy, what are your thoughts on 25 ISO? Does that have worse dynamic range than 100 or is it the same except now you have more headroom. Quote Link to comment Share on other sites More sharing options...

Does that have worse dynamic range than 100 or is it the same except now you have more headroom. ISO100 is the minimum ISO on Canon cameras. Anything below is digitally pulled from ISO100. Long time ago before raw recording these values gave you better roll-off in the highlight when you recorded in h264. With raw recording only analog gain levels are valid. So 100/200/400/800/1600/(3200) anything in between or higher are digital ISO values. if you put the files in davinci resolve they have the same "brightness" as the analog ISO which used as a source to push or pull. So there are no magic if you are trying to use ISO160/640/1250 which were the magical low noise ISO values before the raw era. tweak 1 Quote Link to comment Share on other sites More sharing options...

You can also lower ISO by applying a ML iso reduction to have better highlight rolloff Usually -1/3 or -1/2 stop increases DR with ML so best iso is Canon ISO 100 - 1/2 ML Iso -> 50ISO Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted July 11, 2017 Author Administrators Share Posted July 11, 2017 So I see with the Canon live-view picture, having 12bit enabled in the raw video menu, darkens the image and 11-8bit considerably so. This makes exposure quite difficult with the standard Canon preview, which is why Magic Lantern have the new Framing mode, with the slow fps. I find the slow-fps really bothers me. Although it is amazing they have this at all. Are there any work-arounds to boost the live-view exposure back up to 14bit even though you intend to record at 12?

Jimmy Posted July 13, 2017 Share Posted July 13, 2017 No workarounds yet, that I know of. Does anyone here have a good workflow for raw dual ISO video on mac? Really struggling. Quote Link to comment Share on other sites More sharing options...

Boygetslost Posted July 16, 2017 Share Posted July 16, 2017 Hey everyone, just started using ML on the 5d iii again. really enjoying it. What are the best workflows currently to maximise the image quality in import and post? I don't mind if it involves extra steps, just what ever delivers the better result. Thanks Quote Link to comment Share on other sites More sharing options...

Thanks I think for the very best quality, go through ARC (adobe raw converter). I find i can get more out of the highlights and shadows with ARC than any other software.... I find the tool for tweaking saturation on different colours is really helpful too. If i've shot everything in similar light... I can do a first grade with ARC, save a preset and apply to all the other clips I bring in. Quote Link to comment Share on other sites More sharing options...
Boygetslost Posted July 16, 2017 Share Posted July 16, 2017 Thanks Jimmy. So are you using ARC through after effects? What do you use to convert the MLV's? In the past I used Rawmagic, though I have started using MLVFS. Quote Link to comment Share on other sites More sharing options...

Boygetslost Posted July 17, 2017 Share Posted July 17, 2017 Thanks. after a brief test, I have noticed the colours seem better from Acr and the noise in the shadows seems much better. is there any way to match that quality in resolve? or a way to make Acr less of a pain to work with?

I process the MLVs with mlv_dump, it's a bit confusing, at first, as you have to use Terminal, but it is lightning fast. Quote Link to comment Share on other sites More sharing options...
hmcindie Posted July 17, 2017 Share Posted July 17, 2017 My process for quality: 1. mlvfs -> cinema dng 2. resolve -> editable dnxhd files (sometimes I use these to the end and skip the linking back to the raw files if in a hurry) 3. edit with the dnxhd files 4. online the edit in after effects with ACR to the original raw files (takes a while to link everything as AE wants to link them one by one). 5. effects and grade 6. export a master dnxhd If I need to do some re-edits or different cuts, I'll send those specific files to AE.

kkfok1031 Posted July 17, 2017 Share Posted July 17, 2017 A few years ago before this Crop_rec module I just import the dng into Lightroom, color grade them and export to a sequence of JPEGs. Then I import them to Premiere Pro for further editing. Quote Link to comment Share on other sites More sharing options...
Boygetslost Posted July 17, 2017 Share Posted July 17, 2017 Thanks for the advice everyone. With AE, how do you avoid flicker? I've noticed some of the controls can make the image flicker a little. Does anyone have any workflow recommendations for AE? Like is there anyway to see a diffrent frame in ACR, not just the first one? So far I have been processing the shot with ACR in AE, then adding each shot to a separate comp, then rendering each comp, is there a faster way?

tweak Posted July 17, 2017 Share Posted July 17, 2017 Just use MLVFS and work directly with MLVs in resolve. I do this, the quality is great and workflow is fast. Quote Link to comment Share on other sites More sharing options...
