I just got into videography and I just discovered ML and immediately got it because the focus peaking will do me a world of wonders with my cameras terrible autofocus. Because my camera doesn't have very good dynamic range I want to try using log formats but i dont know where to find them. If ML does not have any log profiles would it be possible to run both ML and cinestyle off the same memory card?
ML doesn't provide any picture style and doesn't interfere with picture style settings. Same with or without ML: If you are using a picture style it will only be applied to JPEG and H.264 (=Canon's own movie H.264 codec implementation). It will not have any effect on RAW/MLV shooting/recording output.
