Poor quality NTSC DVD

I use a UK Panasonic HDC TM700 camcorde using the highest quality HA1920 quality (but not the 1080 50p)
For the first time I tried to produce a DVD in NTSC format as it was being taken back to the USA. It did warn me that there would be a lose of quality when I changed the settingsand there certainly was, the quality was unacceptible. Is the problem that the camcorder is making files differently as it a UK purchase as opposed to if I had bought it in the USA or am I doing something incorrectly in the editing process. (I have had a look at my camcorde settings and there is no options for PAL/NTSC).

Normal quality loss mainly by reducing the image size in DVD_Video [NTSC] has at most 480 lines, his original video has 1080 lines.
Furthermore [NTSC has 30 frames second], [PAL has 25] in converting may have lost too. AMD-FX 8350 / 8GB DDR3
SSD SUV400S37240G / 2-HD WD 1TB
AMD Radeon R9 270 / AOC M2470SWD
Windows 7-64 / PD16 Ultimate

Thanks, yes I think I understand about quality reduction. The second part to my question was are camcorders set up differently according to where they are bought, do they create a different type of file so that mine is set up for PAL and if I had bought it in America it would have been set up for NTSC?

The first question that came to mind was how much video (time) are you trying to put on a single layer DVD - one hour is about the max for best quality.

Are you recording in high definition and then outputting to a standard DVD. The quality would be no where near the unoriginal recoring and would be as Playsound stated.

It should not be a major change from PAL standard to NTSC standard. The camcorder doesn't really matter if it is recording in PAL vs NTSC. Look elsewhere for your problem.

How are you getting the video files from the camcorder to your computer?

The length is 55 minutes.
I am recording in HD and outputting to a stamdard DVD (what else is there?).
When I cahage the settings to NTSC it says there may be a lose of quality.
The video files are downloaded from the camcorders hard drive by USB to the computer.
Are camcorders set up differently from region to region?

Yes, but camcorder TV format that counts only in direct playback to a TV. Computers are blind to NTSC /PAL except for when you go to output.

I think that message may be more from changing from HD to standard DVD. There is a MAJOR loss of quality in doing that.

With that camcorder, you should just be able to copy rather than to download (capture) the videos. Is that what you are doing?

If the video were more in the range of 40-45 minutes, you could product an AVCHD disc with the hardware and discs you have now. The person in the US would be able to watch the high definition video if they have a blu ray player that will play AVCHD discs. The quality would not suffer very much. .

I think I get all of that. Camcorder video files are not the problem for copied videos (only if you play the camcorder through the TV). I am copyimg not capturing.
I think now that I may have not given the right info in describing what I call poor quality through my ignorance. The general quality is ok but there are judering lines across when there is movement, like someone walking as opposed to being stationaery.

Possibly those are interlacing artifacts.

DVDs are interlaced. If your original Video is also interlaced, there may be a field order reversal. Normal is Top Field first.

You can check that using MediaInfo on the two videos. The video on the DVD is *.VOB.

OK, before I investigate that here is something else.
I decided to put it on YouTube and decided to make a standard quality only file for uploading. It came out with the same articated problem as with the NTSC conversion - an artifact line going across horizontaly on movement of and object. I then created the HG (top quality) file and that was fine. Is this any clue?

Yes, higher quality video does not show the problems of a low quality video.

There is a big difference between standard definition video and Full High Definition Video.

You can see that on Youtube, where that are HD video and you can chose the quality on the player.

720P looks far better that 360P.
If your internet connection is fast enough, the 1080P is better than the 720P.

Not all videos on Youtube are HD, just the more recent ones. Carl312: Windows 10 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1GB,240GB SSD,two 1TB HDs.

Found the solution. I have up to know been producing direct to DVD from Edit. I then tried producing a file first, then putting the file in a standalone edit, changed settings to NTSC, got the warning about PAL to NTSC but the DVD came out fine.
Thanks for everyones advice as I learnt a lot of other things along the way.
