Hello, i am using MP4 format as output for my videos. But the problem is when i for example, transcode a flv video 100MB in to MP4 it increases in a size for about 150MB. Is there any tweaks on how to decrease the output MP4 size?

You can decrease (video)bitrate in your mp4 preset (bitrate x duration = filesize). On the other hand, this has impact on quality of encoded video.

Your problem is that the .flv file has a lower bitrate than the one you're transcoding to. Thus, the output file is bigger. The only option you have is to decrease the bitrate, but you need to find a compromise as if the uploaded video is very high quality but you transcode it using a bitrate of 600 Kbps, the output video will look very bad.
