For the past few days I have been doing some stills camera tests for Timelapses. I found out that my 2003 Canon 1D Mark II was the best camera I own for doing timelapses. As it is only 8 megapixels the files are manageable and that will give you a 4K master, its has a higher dynamic range than my Canon 5D Mark III with 12 stops and the batteries on it last about eight hours !
Here is a day to night timelapse shot with the 1D Mark II
For the workflow I have been trying some new things out. I shoot RAW+JPEG then render the JPEG Sequence with Quicktime 7 to get a ruff proxy. If im happy with what I got I take the RAW Images into After Effects and tune the RAW settings to give me a flat image. I then export the RAW Sequences as DXP/Cineon files. Once I have the sequence in DPX format I bring it into Resolve to export a ProRes 422 Proxy. I edit with the proxies then with an XML, conform in Resolve to the DPX sequence, Grade then export the Master at 4K or 2K ProRes 4444. Takes a while but gives amazing results.
I will be doing a lot more in some better locations over the next few weeks so stay tuned.
