I suggest you use MDH 1, because I bought it. Haha, the effect is awesome, but it's better to have light in dark places. Don't need to explain? The highest HD card of this machine is 16G, and it can record for 2 hours. I use high-definition HX 1920x 1080, which can record for 4 hours. If it is standard, the effect is also very good. There are two files equivalent to SP and LP, and you said that the mpeg2 format of 720x576 is very troublesome to edit, which is not as easy to cause problems as mts and avi. 1996 started editing non-editing. At that time, I thought MPG was an uneditable format. You can edit MPG now, but it is still not recommended to edit MPG. Besides, it takes about 40 minutes to generate a film in 2 hours! You also said that MPG format was compressed in less than 40 minutes. Have you ever thought that MPG has been compressed? Even if MPG2 knows, it is compressed. After editing, it becomes visually lossy compression, and you will have a headache in the future! I wonder what software you use to edit compression. I suggest using EDIUS 5, which has fast compression speed and much simpler editing effect. Audio and video are not recommended. The definition of audio and video compression film is not good. Do not believe you can compare!
