Is this possible with ML?

Hello. I am learning RAW video and working on a workflow. I shoot real estate and I am trying to learn video and have it match up close to my HDR photos. I shot this in Dual ISO 100/800 RAW Video 1600x900 upscaled to 1080 final output.

I ran the clip through rawanizer for DNG output only. I took the DNG's and loaded them as an image sequence in AE and cleaned them with ACR but dropped the exposure to -1.5 for the first clip. I did this again but set the exposure to +1.5. I loaded both clips into the comp and set the brighter layer at top and to 37% (to taste) opacity to blend them. I then ran brightness/contrast and shadow/highlight effects on the comp.

Please note I shot this by hand as a test run to see what dynamic range I could pull out of it. focus is iffy also. I used a 5D3 with a canon 17-40 f5.6 I think, manually set between 1 and infinity at 17mm. I am open to any suggestions including any camera settings.

Thanks, and thank you for the awesome software. I have been using it for photos for 2 years now.

I just started running this process this week on my 600d. Im trying different combinations to get the post time down. Best results so far are raw2dng, import to lightroom, clean the frames(I edited one frame and synched the preset to all, A&B frames alike) and enhance them from the raw, export as tiff, run through enfuse gui with sigma all the way up(fastest way with acceptable results. SNS HDR was better but much slower), reload into lightroom, tweak noise and images if needed, export as a time lapse slide show at 24fps.

Because Im on a 600d I am limited to 1600x900 @6fps, after hdr I'm at 3fps. I shoot real estate so nothing moves as long as I go really slow down a slide track. the above workflow takes about 1/2 hour total for 300 frames from camera raw video to exported finish.

The dng was showing black pixels for me, but not after import to lightroom. I could run the dng straight into SNS but the results were bad. Stretching and cleaning in lightroom is needed for my setup. Wish I had a 5d3 lol.

Here is the video (just a test run)

I am having to fight noise do to my inexperience, low fps, and high dynamic range of dealing with interior real estate shots. Plus limited budget I dont have final cut pro or the other fun stuff lol.

I am all ears for ideas.

Thank you ML for everything.

I am not sure if this was ever brought up so sorry for a duplicate. 

Is it possible to create RAW presets in camera similar to what LR or any other program do. The idea is you can shoot RAW with a preset and have it output as a JPG but with your settings. I think this would be a change to the metadata from what I have seen with RAW video workflow tutorials(load to LR, filter, update metadata instead of exporting, then sequence in LR or After Effects). This would take place of the camera's idea of what the JPG should be compressed as vs the RAW format. I have been playing with my 600D Raw video shooting at 1600x900 @ 7 fps on a slow slide rail. (I do real estate so nothing moves) It essentially fast time lapse. After the raw2dng I am simply running it as a preset through LR to a Slideshow time lapse at 24 FPS 720P. But if I can shoot in camera with the preset for a known environment the output files are way smaller in a preset JPG and can just get ripped in a sequence video.

Thanks for all you have done.

Thanks,

I ran some tests today and it worked fine. Just need to fine tune the shutter vs fps. I was using the ettr to set the histogram but a raw image was at .5" for a great recoverable image. the shuttter speed for RAW video was maxed at 1/31 as a low. So I am guessing I just need to open my f stop to bring up the light. I just hope I dont lose the depth of field I want.

The slow glide track will be perfect. I figure about 2 minutes for a 4-5ft track @ 7 fps will work fine as long as there isnt any movement. I usally shoot HDR so this shouldnt be a issue.

I searched but couldnt find a post, sorry for any duplicate. I understand the band width limitation on the 600D cause the sensor to need a huge crop to run the raw video. Can it be run at 1080 at 1-3 fps? My interest is in a fast time lapse for real estate shoots on a glide track rather than normal time lapse move,shoot, move, shoot. I could just have a slow track running on low fps. Nothing moves so I wont have to worry about blur. Speed on site makes this viable for my pricing.

Thanks in advance.

Im not sure what this feature would be called. I do a lot of interior photography. Is it possible to control exposure through a histogram or an S curve when shooting and exposure. Basically say a 3" interior shot has all of the data of the full dynamic range. If you could take pieces of each shutter speed all the way down to the 3" mark and only keep the properly exposed pixels then you would have a RAW file with no over/under exposure and not a massive file. This would be just like HDR but only one file.

I hope I explained this adequately.

Thanks for you time.

Hey everyone,

Quick question about HDR Video processing.

Have you looked into using the SNS-HDR program in place of enfuse during the interframe script? http://www.sns-hdr.pl/ It can be command line driven and does a phenomenal job with correcting light halo by masking. I cant program to try it out by changing the script. The lite version is a drag and drop command line freeware but only takes one bracket set at a time. I use the pro version for my still and its awesome and can run batch processes.

Thanks
