I came here searching for the same answer. Most bluray video is encoded in VC-1 and H264 video and although the format is similar to MPEG2, I don't know if there are encoders that would let you crop and encode to all I frames (I haven't needed to play with those CODECs). It would have little loss of quality, but I'm not sure it would play in all devices. This opens a possibility, encode to I frame only MPEG (TMPEGenc can crop and encode at the same time). So now you have all your pictures lined up (maybe cropped too), what do you do with them? You had to decode, now you have to re-encode into a "movie format" to be able to play the movie.Īs you proposed keeping your bluray rips in the same format, in this example we'd re-encode in MPEG2 format. To get an image you have to decode the B and P frames. B and P frames don't contain an image, they're a description of movement and difference between frames. One supported bluray format is MPEG2 it's composed of I, B and P frames, of those only the I frame is an actual picture (keyframe).
So, the reason you can't remove the black bars without re-encoding is due to the way video is encoded. Do you mean I gave a smart ass answer? I guess I could have been more specific.
Enim, I don't quite get the gist of your reply, it's either missing some words or wrong selection of words. This thread is still alive! Jagabo is the only one who actually answered most of the OP's question. assuming I'm correct about it being a 4:3 DVD rather than 16:9. If you crop 87 pixels from the top and bottom (nothing from the sides) and resize it to square pixels, the resizing should be around 786x402 for maximum resolution. If you want to re-encode it you'd resize it as per a normal 4:3 DVD and crop any black around the picture.

Normally when you run a 4:3 DVD full screen on a 16:9 screen, you'd have a 4:3 picture with black bars down each side (added on playback), but if a 4:3 DVD contains a wide screen image you'd end up with black bars top and bottom (encoded with the video) as well as each side (added on playback).

Does anyone have any suggestion on how to handle this ? It sounds like a 4:3 DVD which contains a wide aspect ratio picture. The quality of the video is nothing to write home about so I doubt it can withstand re-encoding without suffering major loss in quality regardless of the bit rate and codec I might use. When I play the video in VLC at full screen I have a picture that occupies about 70 to 75 % of the screen in the center. As a consequence I always prefer to have subtitled turned on. I am also hard on hearing due to permanently perforated non fixable eardrums. I very often need this especially for non English movies AND where there is a lot of conversation.

This feature is also included in the Android version. After all they are ALL based on Linux and even Beta VLC does a fantastic job on my Android phone.īTW one feature I absolutely love about VLC on the desktop is that even playing at down to 50% speed sound does not get distorted at all. I just wish these media player manufacturers included VLC as the playing application in the device.
I can get away with it if I use VLC but standalone media players can't handle it ! Unfortunately MediaInfo utility does not reveal the application used to rip the file. Now if I use the crop function in VLC I have to crop 87 pixels from top and bottom making real resolution like 720x402. Under normal full screen playing condition I have black and not so black bars all around. The tools -> Codec Information under VLC gives the resolution as 720x576. Just to give you a bad example of ripping. Even if you could "remove" them without re-encoding as you describe, it probably wouldn't reduce the file size much at all. One question which comes to mind though, is why do you actually want to crop the black bars if you're not going to re-encode? Unless the edges of the video aren't nice and sharp (which they mostly are on Bluray) I'm not sure I quite see the point. You can add crop values to MKV files by running MKVMergeGUI and opening the header editor from the file menu, then use it to open an MKV. I haven't played with cropping that way in quite a while. I "think" VLC handled the top and bottom crop values okay.
Last time I tried it, I think MPC-HC made a mess of the aspect ratio if you added cropping to the side, while it ignored top and bottom crop values.

In practice though, it's not very well supported by software players and completely unsupported by hardware players (as far as I know). In theory, you can mux video with black bars into an MKV, set a crop value, and the player will crop that amount on playback. MKV has a crop flag as part of it's specification.
