I'm using MediaRecorder to record a video. It isn't clear to me what parameters I should be using to change the quality of the image, assuming the size of the video remains constant. For example, I want to always create a 640x480 mp4 video. What parameters can I adjust to increase or decrease the quality?

You have to increase video encoding bit rate to increase the video quality using setVideoEncodingBitRate()
in MediaRecorder
.
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
mRecorder.setVideoEncodingBitRate(4000000);`

You can try using
recorder.setVideoSize(640, 480);
recorder.setVideoFrameRate(16); //might be auto-determined due to lighting
recorder.setVideoEncodingBitRate(3000000);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);// MPEG_4_SP
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
or
CamcorderProfile cpHigh = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
recorder.setProfile(cpHigh);
For setting high quality and low quality parameter see here

try this one u can solve problem
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
String path = Environment.getExternalStorageDirectory() + "/file.mp4";
mediaRecorder.setOutputFile(path);
