How to encode video for the web
This is a common question that many people have. The answer is somewhat simple. The best format to use for encoding when the final outlet will be the web is the h.264 format. Other options include AAC and MP4.
When exporting for YouTube or similar services, the optimal resolution is 640*480 or 720*480. Which matches the regular resolution used for the DVD format (MPEG2). In comparison, HD and fullHD are 1024*720 or 1280*720 and 1920*1080. The difference is whether or not the video is in wide screen format.
Depending on your software of choice the exporting process might be a little different. The important information to keep in mind is the resolution and the bitrate. A good bitrate for high quality video would be 3000 kbps.
The next question would be the FLV video files. Videos being displayed on the web are usually in the FLV format, which stands for Flash Video. A simple strategy for converting between FLV and h.264 or MP4 videos is to use the FFMPEG software.
Here is a simple example:
MP4 > FLV
ffmpeg -i input.mp4 -vcodec copy -acodec copy output.flv
FLV > MP4
ffmpeg -i input.flv -vcodec copy -acodec copy output.mp4
