Panasonic V201 digital CAMCORDER can someone point me to a thread that explains this 1) recording in avchd/iframe as opposed to mp4 see 2 below if I use avchd I have 4 options 1080/60p p progressive /I interlace 1080/60i HA/HG/HE 2) I also want to know about file size and hours. I want to record on the camcorder and burn to a dvd-r on my pc. The camcorder comes with Panasonic HD LE writer 2.0. I recorded for approx. 2.5 hours using avchd setting with 1080/60p I used the LE writer it says it would take 5 discs and it takes about 4 hours of time per disc. I don't have a bluray recorder on my pc or a home bluray player or a new flat tv. How do I equate file size to hours when it comes to the final dvd. If the file on my cam is x number of gigabytes how many regular dvd's do I need. I read that 1 hour of 1080/60p is about 12gb of file space, according to the camcord manual(16gb gives 1hr 20 min) But what does that equate to when making a DVD movie. I would guess about 21 some gb? (Im thinking because the le writer said approx 5 discs and discs are 4.2gb) is there a rule of thumb./chart, webpage to show how to calculate I am not sure what file type the cam stores in avchd? Im thinking I should use avchd 1080/60/I HG or HE to get what I want. My main concern good quality picture without having to use so many regular dvd's and taking so much time to burn sorry for long post I am a video dummy I guess.
