* Install Mediainfo, and check whether the video coding and code rate resolution is greater than or equal to 640x480, and the code rate is greater than or equal to 1Mbps H264. Adobe Media Encoder CS4 of AAC MP4 package is set.
Settings Settings are on.
Format: h264
Preset: Don't worry about your own settings, it will be customized.
The exported audio and video are marked with multiplexer labels.

Frame rate: Use the same frame rate as the source file.
Field Order: None (Line by Line)
Pixel aspect ratio: try to use the same as the source file.
Introduction: Gao
Level: The higher the decoding level, the higher the bit rate setting:
Generally, VBR 1 time or VBR-2 times (with uniform time and code rate distribution) exceeds 1Mbps. Unless the resolution of the source file is large, 1pass can be used.
Target bit rate: greater than 1Mbps.
Maximum value. . : Look at the audio label yourself.
Codec: The bit rate of AAC(LC) later version+1 +2 is set below 56Kbps, please reuse it.
Output channel: stereo
