Hello guys,
I'd like this topic to be a consistent space for slow motion video samples shot raw 60p at various 16:9 resolutions with the 5D Mark III and all your experiences with it.

The main problem I encounter when looking for these videos is that many people trade the 16:9 aspect for more recording time and thus shoot their slow-mo raw sequences at super-wide/anamorphic ratios (like 1:2.35). This is absolutely ok but I think that there are many people like me regarding the aesthetics of 16:9 to be more suitable for internet videos and most music videos.

Therefore, I'd love to see the real world video examples which would show how intercutting the 25p 16:9 raw footage shot at 1920x1080 with raw slow motion 60p 16:9 sequences shot at lower resolutions actually looks like! It would be good to find a good compromise between recording time at least 20-30seconds and resolution which would still look decent at 16:9 with the rest of the 25p 1080p footage.

I guess I'm not the only one considering the 5D Mark III for shooting music videos in raw. That's why I'm curious how incorporating slow motion in resolution lower than 1920x672 would go with the rest of the 1080p footage. At least 30 seconds of 60p 1920x672 would be the ultimate answer but as long as you get only about 6 seconds even with the fastest cards (because of the 5D's buffer), we have to go a step down in 16:9 resolution.

From what I've been able to find, you can record at different resolutions at 60p allowing the post-stretching to 16:9 aspect and each of these resolutions give you a different recording time depending on your CF. These 60p "16:9-doable" resolutions should go something like this: 1920x672 (16:9), 1600x560 (16:9), 1472x516 (16:9), etc... I'm not sure if I got the numbers correct and I think that there is one more 16:9 60p resolution between 1920x672 and 1600x560 but you get the point...

Seeing a video showing similar or same scenes shot with the above specifications would help a lot! I haven't seen any slow motion 16:9 intercutting with normal speed 1080p test on a 5D Mark III in raw yet.

Please, with your tests also specify the following: your CF card, 16:9 resolution used, frame-rate (mostly 60p please, although 50p can be interesting as well), recording time you achieved with your CF at given resolution and lenses/filters used.

Excited to see your results!  :)
