Hi, I`ve just converted an MPEG2 file to DVD with Nero and would like to know how to change the picture aspect. I`ve got a kind of 16:9 in reverse (as on the original MPEG2) In other words the screen is part blank left and right instead of top and bottom. Can I alter the DVD picture aspect to suit my TV (I don`t have wide screen at present) like 4:3 or 16:9 , or do I have to reconvert ? Thanx PAD48
i do believe as to my knowledge that has to be done at the converting stage. if you have NTSC source and have a 4:3 video source you would want to have resolution at 720x480, for 16:9 probably something like 720x380 would be fine. to make it somewhat more clear try making the viewing aspec ratio for 4:3 (Full screen) 720x480 and 16:9 720x380. If you still have the left right border problem as blank then try adding borders to it in avisynth. AddBorders( Left,Top,Right,Bottom ) change those to a number suitable to your video source to rid of the blank spots from the edges. I would normally say somewhere between 3 and 10 should rid of those borders from left and right depending on how large of a blank spot you get from your video source.
Okay, I`m gonna try this out as soon as it cools down a bit (35c outside and getting hotter !) Thanx for your reply and I`ll get back if it works or doesn`t. PAD48
Hi Leechness, didn`t see that it was you that had replied to my 2 separate threads. Thanks, it`s kind of you to take the time. As you`ve gathered I`ve got a lot of questions and it`s much more interesting posting them, than reading FAQs and manuals. Thanxs again PAD48
hmmm, it's very common to see black bars on left/right like a reverse widescreen WHEN VIEWING A NTSC 4:3 Fullscreen ON PC screen. But if this is happening on a standard TV... you got a problem. the framesize ie. DAR needs to remain 720x480 to remain full D1 DVD complient. You can choose to make a 4:3 fullscreen or 16:9 widescreen<-- but the DAR remains 720x480
i think its possible that the cause could be from his/her avi source. Whoever made the avi may have cropped too much from the sides for their own reasons. But im not 100% to say that is the issue. I have done and gotten the same thing he has before during my first few avi to dvd as well, but when i started adding the borders with avs script it went away for good.
Hi, I´ve just checked the original and it`s ok. 16:9 as it should be and MPEG2 (SCVD/DVD). I`m going to convert it with nero again and get back. PAD48
i highly doubt that redoing it again the same way will fix it. You probably really need to add paddings to the video. And like Headborg says. "DAR needs to remain 720x480" you can however change the "video arrange method", but you must keep its at 720 x XXX; XXX marks it to be full screen or wide screen view. i use TMPGEnc, so i really wouldnt be able to help with how to user nero, but if i knew how to use nero i would be gladly to help. wish i could though.
Hi leechness ! yes, you`re right, reconverting didn`t change a thing. Clone recognised the VIDEO_TS folder etc but.. I´m back to where I started. The picture I end up with is a "rectangle" inside a "rectangle" - the latter of which is, of course, the TV screen aspect - although on the original with Showtime everything`s as it should be: 16:9. The original file , as I`ve already said, is an MPEG2 ca.800Mb and there`s no reason to assume there`s anything amiss - if you believe what AVIcodec tells you. Back to the drawing board! PAD48
part of the problem could be a combination of two things...(1) the quality of the DVDauthoring software (2) the Media Player software. (1) a high quality DVDAuthoringSoftware(examplevd_Lab_Pro) allows you to specify a tag in your DVD that tells the Player how you want to Display a 16:9 on a Standard TV(4:3 FullScreen) You can specify (Pan&Scan) which makes it fill the fullscreen or Letterbox(display keeping full aspect..but shrinking the image and placing black bars top/bottom. I don't beleive Nero allows for this. Then 2: Some Media Players like WinDVD will read this Tag and do as instructed. Other players...just have 1 default way of displaying it..fullscreen. There's always conversion going on...a PC has square pixels...a standard NTSC TV has rectangular pixels..this is why a Professional Video Editing System relies on TV monitors so you're seeing exactly "how" it will be seen when finished and displayed on TV.
Hi Guys, Hi, well the problem seems to have sorted itself out ..I`ve got 16:9 now on my TV - which is what I was after, and I don`t have to zoom in etc.. to see what`s happening. Here`s the log as I remember it: 1. SVCD @ ca 800 Mb converted with aspect automatic in Nero v6.6 2. Burned with Nero on +RW - ended up with a rectangle inside a rect. 3. Reburned with Clone - same thing 4. Created DVD Film daten with Clone 5. Reburned film daten with Clone - and I got my 16:9 What do you make of that ? Regarding aspect, what`s the norm ? I don`t have widescreen yet so what should I set the aspect to when using these programs: a) Nero b) DivxToDVD and ConvertXtoDvd (VSO) options are "Force 4:3 or 16:9" c) ImToo DVD Creator options are "Default" "Letterboxing" "Pan & Scan" ans "Full Sceen" If you can give me some advice here it would save a lot of time. Thanx PAD48
