I posted a preview of my developing workflow for the Canon Rebel T5i. Allow me to go further into detail of this workflow.
I'm using Mepg Streamclip to transcode to Avid DNxHR and creating a rough edit inside of HitFilm 4 Express. From there I export a PNG image sequence and bring that into Lightroom where I utilize the basic correction tools, noise reduction, sharpening, lens correction and dehaze effect. I find these tools to be very effective at their individual jobs and makes for a very fast workflow. Once I've applied correction with Lightroom I import the sequence back into HitFilm and use HitFilm's built in tools to color grade and finalize my edit.
What nice about the image sequence workflow is that if I want to change after I've exported the corrected sequence from Lightroom. I simply select the frames I want to modify, make the changes and export them. Lightroom keeps everything in order and can overwrite the original files without change the order of the sequence. HitFilm automatically detects those changes and the changes can be seen inside of HitFilm immediately.
If you're a student or on a budget such as myself, this is a cheap way to get quality noise reduction, sharpening and Lightroom's custom lens profile corrections for cheap ($9.99/month). You can also use VSCO film presets with this workflow and get some spectacular results.
