![]() ![]() ![]() I think most cameras will record varying lengths, because the compression depend on the content: a talking head with static background takes up far less file space than a action wedding car chase. This is a hard limit set by the file system on your memory card (FAT16), there is no way around it. You still haven't said anything how you want to deliver your work (DVD? web? file?) and how good you are at editing this stuff. while the video recording of a point&shoot would be absolutely sufficient, the sound recording (no audio in) isn't so great. that either leaves you with a decent camcorder, or a video dslr. Seminars and talks: without a dedicated mic or a direct feed from the sound board, almost any seminar video i've seen is deadly boring, because it's so damn hard to understand/hear the speaker. IMO, recording video for a wedding is taking snippets (10s-5m) and editing them into a 5m-20m video, but I am also not a wedding video guy, maybe they could offer some better opinion. it's a nightmare to edit, and watching it unedited is as interesting as watching a security camera. Weddings: i personally can't see any application where you would record 3h of footage in one go. it would have had been really helpful if you would have offered them a bit earlier. This is sort of the first time you finally mention what you applications are. So, what do you want to do with your video? and how much is your time worth editing/dealing with this problem? unfortunately, the interlacing is not easy to remove, degrades in editing, and isn't easy to take from NTSC to PAL (and visa versa).Įvery other video spec is progressive, meaning each frame is a full frame, no interlace BS in there. again, it was necessary for broadcast in the 40's and 50's, but now everything is digital, interlaced signals are a thing of the past. (each frame is divided into 2 fields, called upper and lower, and they interlaced each other line, basically showing half of the image with 60/50Hz). The interlaced NTSC has even lower rez than the interlaced PAL. nothing else needs a interlaced video signal. The main issue at hand is the interlacing, needed for broadcast to analog TVs. Sorry, i was referring to all current cameras.Īnyways, I am in my predicament, I can't buy a new DSLR, so I would prefer a dedicated video camcorder to do all the video work. It is 50/60 field per second interlaced.What do you mean? I have the 40D, that doesn't record Video? A lot of people think TV is 25 or 30 Frames per second but this is untrue. Almost all broadcast TV and DVD’s are Interlaced. Doing this half’s the bandwidth wile keeping a high ‘field rate’ such as 1080i 50Hz/60Hz to keep a smooth flicker free video. ![]() One field scans all the even lines of the original frame then the next field scans all the odd lines of the next frame and continues to do this. With interlaced video the frames are cut down in to fields. Basically for progressive video such as 1080p refreshes the screen with complete frames scanning from the top to the buttom but with interlaced video this does not happing. I’m sure all you guys know what frame rate is but almost no one knows what field rate is. If your video will be showing in the USA then that is a NTSC country so set your camera to NTSC. So if you intend your video to be showing in the UK that is a PAL country and your video will be showing at 50i so set your camera to PAL (and if possible 50i or 50p). If you intend your footage to be showing on TV then it is more important that you choose the correct setting for smooth results because TV systems will only display video in field rates correct for each country. But keep in mind many digital cameras work better at lower frame rates so there is no point setting your camera to record in 60 or 120fps just for the internet unless you intend to do slow mos. Even if you upload a higher frame rate it will be converted down by YouTube. ![]() If you only intend to put your footage on the internet then frame rate does not really matter so much because sites like YouTube will change them to be either 25p (PAL) or 30p (NTSC) automatically. For example PAL would be 50i, 50p or 25p or NTSC would be 60i, 60p, 59,9i,59.9p or 30p.Ĭhosing the correct settings for recording. Nowadays PAL and NTSC only refer to frame rates and field rate or multiples of them. PAL: 625i (576 active lines) at 50Hz and NTSC: 525i (483 active lines) at 59.9Hz and nothing else.Īll old video formats like DVD, VHS, U-matic, Betamax and even standard definition digital TV use the above rules so they would be compatible with TV’s designed for PAL and NTSC analog broadcast. The amount of scan lines and field rates were as follows. Technically PAL and NTSC do not get used any more because they were old analog TV broadcast formats. Here's some info i thought would be help to some people ![]()
