I have A Sony TRV 340 camcorder and a Sony PCG GRX 560 laptop. When transferring video using DV Gate, I find that about 3 minutes of tape turns into 650 mb. From other CD's I've viewed, I know it's possible to put at least an hour and a half of tape on them. What do I need to do to place a one hour tape onto one CD? Other programs I have are Adobe Premier, Pixela Image Mixer, Smart Capture, Screenblast, and Movie Shaker. Will any of these programs better maximize space while retaining video quality? Thank You |

Remember that when you import video via firewire, the compression will be the same as the compression on the tape itself. In this aspect, the video footage will take up approx 13GB per hour of footage. You can work with this footage, assuming your hard drive size can sustain it, and when you're finished with the product in its full quality, you can export the project in a compressed format, such as a mpeg .avi or even a DivX encoded file if you get the codec and serial to do so. I recommend using the full-quality video to work with initially and then export to whatever compression setting you need. I'm still toying around with different export options to see what works best, but if anyone has any good ideas for what exports at good quality from Adobe Premier or EditDV 2.0 (old, I know, but it does what I need), please let me know! |

i make 3d animations and understand the huge file sise problem, i suggest that you burn a uncompressed version iether to tape, or dvd data, this way you will always hav a back up, if it doesnt fit onto disc then chop it up make note of frames !, but another way to reduce file sise once you hav your master safe, is to use macromedia flash, compress to iether fla or swf, this will reduce say about 2 gigs into much less than 100mb, and as you say there is a compromise between quality and sise, up to 550/400 is pretty good, at 720/576 it starts to pixelate, in scenes that are less defined !!!, but i think the best rule is to keep a none compressed master that way you can always make it smaller if its needed for web applications or projecting or mpeg 2 for tv, if ya wanna know what i mean hav a look at this animation http://www.bee-unlimited.co.uk/show%20real.html each clip is around 2gigs, so the whole vid is very large but on the web as fla is about 25mb. enjoy the film and i hope this may hav helped you ??. b.u. |
