The video app on the Huawei Ascend Y300 is what you would expect on a low to med range handset.
The 5MP camera performed well in the camera department, but won't be getting full marks for it video capabilities.
There is not an option to change the frame rate, and the video slightly jutters upon playback. However, it must be noted that the audio reproduction on this device is actually very good.
The video also refocuses whilst recording without any prompt to do so. In the short example the Y300 refocuses five times, although this might be due to the panning motion of the footage.
Needless to say this was still something we didn't require, and we couldn't stop the Ascend Y300 from doing it, which was frustrating.
The flash works well when recording if the subject is close to the handset. If that's not the case, the single LED located next to the lens struggled to illuminate when testing.
Also you have to decide if the flash is required before shooting, as there is not option to change this setting whilst recording.
There is an option to change the video size before recording between VGA (640x480) and MMS (176x144) depending on your requirements.
