Stretched video

[atran]

Ok im new to this and I am wondering what I am doing wrong. I ripped a DVD to my hard-drive and it ripped properly. It seems the video isnt exactly 16:9 ratio becuase when I play it on my widescreen, I still have bars (along with 3 other DVDs I just played on it). Anyway, I then opened up this .vob file in MPC and it played properly. I went to the properties I see this: 720 x 480 (AR 16:9). Ok now onto the part of turning it into a encoded video. I then opened up the file into megui and encoded a short segment just to test it. Everything was stretched vertically and when I looked in the properties it just said 720 x 480. Could someone tell me what I am doing wrong.

Also, all the dvd is spread accross 8 .vob files. Is there a way for avsynth to open them up in like megui so the encode all in sequence?

MPC played it unsquished because it was reading the DAR flag in the files and it was resizing it to the proper 16:9 aspect ratio. When you fed the files to megui and encoded no resizing was done so it was kept at the original 720x480 resolution which is why it looked squished. You aren't doing anything wrong as the file was playing back exactly as it should since you had no DAR signaling.

Just load them into DGIndex and create a d2v project file and load it into avisynth using DGDecode.

Ok you said I had no DAR signaling. How would I get DAR signaling so it looks normal?

Mux it into a container like mkv or mp4 and when you do so set the DAR as 16x9. That or when you load it in the media player set the Aspect ratio to 16x9 and it will display it correctly.

Do you know how I could do this with megui? I seem to get the best results when I use megui, so I was wondering if I could use it to get that job done too. Or is there a tool to edit something in the mkv to change the ratio to 16:9.

Thanks.

U can still use meGUI for encoding while using other app for muxing.
The MKV muxer in megui is very basic. Mkvmerge, on the other hand, is one of the most featureful apps. You can also use avi_mux_gui.

In Mkvmerge:

Ok that seemed to kinda fix it. When I play it in media player classic it still isnt in the right porportion, but when I play the DVD with MPC it looks right. Now when I play my encode in zoomplayer, the aspect ratio is correct. How do I get it to work in both?

[atran]

Wait scratch that, MPC doesnt display the origanal correctly eather :p.


Cancel that, I just had my MPC classic setting messed up when I was fooling around with it. Works fine now :D

If you use megui to generate the avisynth scripts you can simply check the "clever anamorphic encoding" box and megui will take care of the aspect ratio. I encode to mp4 and never had to set anything manually when muxing.

ok I have another quick question about that. If I encode my movie in megui with x264 then use mkvtool to input the DAR, will I be loosing any quality? Like would I get better quality if I DAR in megui so its not squished to begin with? Im asking these because every time I change the DAR in megui it never puts the DAR in and I have to use mkvtool to change the DAR.

[Skelsgard]

DAR being "Display Aspect Ratio" only alters the size at wich the frame is PLAYED, not the ORIGINAL frame size.
MKV, as MP4, AVI or OGM, is a container, not a format. When u load the container with a stream, the stream is not altered.
Think of it as a gallon of gasoline. It doesn´t matter if it´s in a metal or plastic recipient (containers) or even in your car´s tank (another container), it´s still one gallon of gasoline.
This is the same. If your encoding with megui to H.264, the stream will be H.264 it doesn´t matter if it´s in a MKV or MP4 container.
So u can set the DAR whenever u want (megui or mkvtool).
*Megui exports to containers as well as raw stream.

Um im not exactly sure what that meant relative to my question. Here is an example of what I am talking about, but not what I am doing.

Taking the movie and encoding it with megui with DAR of lets say 1.35
Then use MKVtool to change it so 2.1
Then change it again to 2.35


OR

Encode with with megui with DAR of 2.35.

Would there be any difference in quality between those 2 videos? I am asking this because if I try and change the DAR in megui, it doesn't seem to change so I have to use MKVtool to remix it.

Again, no, there will be no difference, as DAR is "Display" aspect ratio (the ratio at wich it plays).
U can set the DAR in megui, mkvtool, or even in your player, the quality will be the same.
Now, if u don´t get the DAR properly when encoding with megui, use mkvtool to set it right.
