The clearance member can take many forms such as a textured portion on the second sidewall that includes evacuation passages which provide air in the internal volume access to the valve element, a permeable element covering the valve element, and a rigid or compressible structure that spaces the second sidewall from the valve element.

The invention relates to a video compressing and encoding method with an alpha transparent channel, comprising the following steps of: inverting the acquired video image to the image in the format of RGB or YUV4:4:4 / YUV4:2:2 / YUV4:2:0; compressing the acquired data in the alpha transparent channel in a no-damage mode; encoding and compressing video data for the video image in the specific format according to the frame format of MPEG-2 I and saving the compressed data in the alpha transparent channel in the compressed data structure of the video image. The method realizes the encoding of a specific video picture, can use a standard MPEG2 encoder for encoding, and effectively reduces video bitrate when ensuring the high quality of the video so as to realize the video data encoding with high quality, high efficiency and low cost. Because the data of the alpha transparent channel and the compressed data of the video image are saved in the same file, the video compressing and encoding method not only simplifies the process of processing the image at the later period and the information sharing between file management and a program, but also reserves the original video which is not added with the data of the alpha transparent channel.
