QT file size off the chart

Question

i am exporting a basketball game that i have off a camera. the file is 13 gb already. i want it way smaller but still good quality to watch as a quicktime. when i export as 422 it bloats to 44 gb. if i use h264 it is small - under 1 gb, but very ugly. i have exported tons of video before and usually using 422 makes things smaller - not larger.
DV, 720 × 480 (640 × 480), Millions
16-bit Integer (Big Endian), Stereo, 48.000 kHz
this is the native file info? any help?

The file size is directly proportional to the total audio + video data rate.
i want it way smaller but still good quality to watch as a quicktime.
A "quicktime" movie is any QT or third-party data compression format in an MOV file container that is play on a system having properly configured QT component support. There a dozens of possibilities which can be combined in hundreds of possible ways with settings offering thousands of possibilities. Can you be more specific regarding your goals?

H.264 is a very efficient codec with a wide range of useable video data rates. Depending on your requirements for display dimensions, minimum quality acceptability, and/or maximum acceptable file size, there should be a data rate the will server your needs. Basically, SD H.264 video can be exported in the range of 1 to 18 Mbps depending on what your will settle for in terms of quality and file size for a particular display size. Quality is proportional to the data rate which is inversely proportional to the file size. What you need to to is find a happy medium between these three requirements.

This looks like a video editor capture of camcorder content in standard definition. It likely has a total video data rate on the order of 28.5 Mbps (about 13 GBs per hour of content). Since your previous H.264 export indicates a combined total data rate on the order of 2.2 Mbps, you might try manually exporting the file limiting the video data rate to something in the 3 to 4 Mbps range and an AAC stereo audio track of 160 Kbps @ 48.0 KHz. This should improve quality and provide a target file one quarter to one third the size of your original "source" file. Since you did not provide any information regarding the aspect ratio, I cannot provide specific dimensions settings here. (I.e. if source was PAR 16:9, then you might target a 853x480 display size or 640x480 if in a 4:3 for smaller file size or 720x480 PAR encode for 640x480 playback if you want to force the video data to encode at a higher data rate. (I.e., H.264 video is adaptive depending on the content and settings used.)
I think it is a file that was captured at a high def type setting - although it was not high def to begin with. thus the huge file.
The original file on the camcorder may have been HD, but the captured file is SD and the file size of 13 GB is quite normal for an hour of content using the DV-25 codec. (DV-50 and DV-100 files would be double and quadruple this size.) This is simply a low efficiency (i.e., low compression format) which provides higher editing quality at the expense of file size.
