tmpg cropped problems on .

[afrodocter]

i made a dvd and when it is played back on a tv the sides are cropped.


i have some mpg2's encoded with tmpgenc plus. they all have different source resolutions. some come from 352x240 mpg1's, 480x480mpg2's, 720x480 avi's, and some come from 640x480 mpg2's.

all of them are now in 720x480 mpg2's except for one which is in 352x240mpg1.

they files all look good, and i have burnt them to a dvd using tmpg dvd-authorer. i am having a cropping problem when it is played back on tv. the sides of the video are not shown. this is not a problem with the mpg1 track. but the 720x480mpg2's do have the cropping problem.

ive read that this is over scan error but i dont think so, because the mpg1 looks fine.

ive also read that changing the "video arrange method" in tmpgenc to "center keep aspect ratio" will give me some nice black border which will fix the cropping problem. however since some of my files have a soucre res of 352x240 the 720x480 "center but keep aspect ratio" encode makes a huge border which is not acceptable.

i think this is a common problem but i have not found a solution.

i want to play my 720x480 mpg2's on a dvd player without them being cropped. i am will to add black bars if that is neccesary but im not sure how.


thanks for any advice.


on a computer all tracks look good.

All I can say is that, if resolution of input file is lower than the output, the idea to select "center, keep aspect ratio" as video arrange method leads to black stripes around picture and if resolution is higher, cropping is inevitable. You can select "center-custom size" (set as appropriate) or you 'd better experiment with "full screen" setting. However, with vcd as input, things may be complicated because I do not know the affection of its Display Aspect Ratio, which - unlike mpeg2 clips - varies.

Hi there guys,

I know this is a very old post, but let me try this subject again:

I've tryied the same way as answered, but I got the same problem as "afrodocter" posted.
I'm using TMPGenc Plus to encode the videos - I've already tryied "Full resolution, keep aspect ratio" and "...keep aspect ratio 2"; I even tryied "No margin"; but when I use DVD Tsunami to mount the DVD, with menu and so, and then mount the ISO, with TDA, the result on TV is the same: a croped video on TV.
"afrodocter", please, did you have solved this problem?

In a matter of fact, I've tryied any combination possible with the Display Aspect: 1:1 - 4:3 and all Output Aspect, and don't know what to do!

Thanks for any advice!

how is it cropped? all tvs are cropping a bit(called overscan) so if you want the entire image you must add black borders, using the custom size tmpgenc.

the result on TV is the same: a croped video on TV.

Of course. Everything you have ever seen on TV has had ~5 percent of all four sides hidden by the bezel of the TV. This is intentional on the part of TV manufactures and TV industry. It hides defects at the edges of the picture and problems with positioning and linearity in the TV hardware. You've never noticed before because you didn't have an external reference to see what the "whole" picture looked like.

Almost everyone here who complains about this issues is trying to view fan-subbed anime where the subtitles are placed too low in the frame for TV. If you need to fix this you need to add black borders to the frame so that the black borders fall in the overscan area. In TMGPEnc set the "Video Arrange Method" to "Center (custom size)". Set the custom size to about 688x460 (assuming 4:3 content). Continue to use a 720x480 frame.

Gee thanks guys,

I didn't realize that the new flat televisions, I'm mean, not the plasma ones, and HDTV monitors, but the average TV models on market, had this problem. I thought only the old round tubed TVs had this "safe frame" problem.
Well, I read the article above and have no more doubts.
But, I can't help that I feel a little confused as Adobe Premiere and Adobe After Effects, and the like, claims (if I'm not wrong) that the PC square pixel (1.0) is corrected by the DV NTSC output format (pixel aspect 0.9).

Anyway, I'll do as both of you've said: I'll try and test another "Video Arrange Method", and see what I get.

Thanks again.

You can use FitCD to figure out border sizes for different frames sizes, PAL and NTSC. Don't bother getting the video to exactly fit your TV. They vary in the amount of overscan.
