Description: The main explores the relationship between what the EV record screen picture quality, sound quality and video size. By setting different configuration testing, we found that the bulk of the level or quality of space, and the sound quality has little effect on the size of the video.
For different screen size configuration record one minute space occupied by a simple test.
The results are as follows:
a simple test we can see that, in addition to the quality level, other configurations are not much effect on the video size. To control the video size, mainly to set a good quality level.
My own test results are as follows (the size of the audio quality may be affected by fluctuations or other factors):
| Picture | Long record screen | Video size | It expected a class of video size (3 hours) |
|---|---|---|---|
| Ultra-clear | 1 minute | About 7M ~ 9M | About 1.6GB |
| Original picture | 1 minute | About 20M ~ 25M | About 4.4GB |
It has had a long record screen, the image quality of the original painting level 100 minutes record screen, video size 2625M, verify the above conclusion.
For me, a lesson 4GB ~ 5GB still acceptable.
