I just need to know what the rules are with exporting videos. For example, I have a 4 min Ae project that has lots of motion graphic/HD video work. The video consist of scaled down HD footage that floats around in 3d space and the camera moves past certain video clips threw 3d space for the whole 4min. there are around 450+ floating hd frames for the whole video. The video needs to sent to the client for their review on it. So im exporting it as an FLV so i can bring it into flash and change it to a swf for uploading to the web. Now when I export the video I make the dimension size to 620x350 instead of 1080 and I keep the audio bitrate at around 60kbps. But what my main concern is that if I lower the bitrate for the video, so I can keep the file size small the video quality starts to go. So my question is there any way to keep dimension size at a large size and still have good quality video with a low file size? Im using adobe media encoder 5 to do all of my encoding as well.
