i did forget to mention that an fps of 23.976 would yield a qf of 0.101. i sincerely hope this answers your question (at least settings-wise).
50 mb? okay... output resolution would be 176x132 with a video bitrate of 56 kbits/sec (qf of 0.101). assuming that this is a 2-hour movie, this should yield a 50 mb h264/mp4 file. oh i almost forgot, you'd have to remove audio to do this.

I have a bunch of videos on hand now, I merely realized there would be a way to compress them, you did help me a lot.
Hi, wickrama lasantha, use the method describled above. However, for your case, you'd better to cut some unnecessary part first, so that you won't sacrifice too much quality. Hope it works for you. Best regards,
