[WONTFIX] 550D: Overcranking and 1080p@60fps

[Dunc101]

Hi,

I have been trying achieve over cranking on my 550D/T2i and I wondered if anyone has had any luck at getting really good results?

Also would it be at all possible to make a 60fps override setting in full 1920 x 1080 HD for the next version of ML?

Thanks

All the best

That's a [WONTFIX] probably, since the original Canon Firmware does not have 60fps FHD and the camera sensor/buffers don't have that capability too


As far as SLO-MO is concerned, you can only can only achieve that in 720p if you aim for 25/30 FPS at 1/2 speed

I'm leaving this topic open but marked as WONTFIX until an official reply from A1ex

Is it not possible with a Class 10 card? Surely the only limit is the write speed

(I'm replying even if the topic is locked to avoid spreading false information)

When looking at FPS in video mode we have several limits:
- Canon's firmware. This includes the encoder used to compress video. Each firmware has multiple encoders, one for each combination of supported resolution AND FPS

- Video buffer, this is linked to the previous point. The camera can process only much information before running out of it. You'll notice that when using ML bitrate control, for example.

- Processor and sensor readout speed (the latter limits live view to about 39FPS)

- SD write speed, the least important of the group if you ask me.

Max was 35p on 60D/600D.
