Frage von nahmo:
Hello,
if I put my uncompressed AVI (; 720x576, 16:9 / 1.422) than TMPGEnc. In an MPEG2 with 640x360, encode 16:9 screen, I have previously mentioned, and the bottom thin black horizontal bar in the final file. Say, the picture is not full picture.
Does anyone know why this is so, or can someone give me some advice as I get this fixed. Stand straight when something on the tube.
Thanks and greetings,
nahmo
Antwort von RickyMartini:
If one adjusts 640x480, there are no black bars.
The source material has the PAL DV 16:9 (; anamorphic) resolution. Therefore, one should use this setting synonymous.
576 x 1.44 = 1024. Thus, results in an anamorphic resolution of 1024 x 576 (; 1.777 = 16:9).
Antwort von tommyb:
The problem is that the material is not the aspect ratio of 1.42222 is but 1.458 (, something). This happens when the material as DV - video will be interpreted.
TMPGenc then assumes that the material would have actually 1049x576 pixels when it is correctly "entstaucht. It scaled down the material in compliance with 1.458, it comes at 640x352 (; 576: (; 1049:640) = 351.42). As the final resolution will be 640x360 (; ie 8 pixels) more in height, add TMPGenc 4 pixel thin black stripes, a top and bottom.
This problem can be circumvented, for example, if one ignores the Runterskalieren the aspect ratio. That is, one "squeezes" the material in 640x360 (; TMPGenc do not know, but in principle it could) give such an option.
Antwort von RickyMartini:
TMPEGenc version I've downloaded the trial and determined that it is 640x480 with no horizontal bars with
PAL DV is
Widecreen. Any deviation of this resolution produces these beams.
Antwort von nahmo:
I found the operation to disregard the aspect ratio to "filter". Now the bars are gone and it is synonymous looks good.
Did I understand correctly, that is now the picture is compressed horizontally by 8 pixel? And I, if the destination format should be 640x360, no other possibility than compress or which source format would be suitable for this?
Thank you for your trouble times already.
Greeting

Antwort von tommyb:
The 8 pixels should not make a lot of what concerns the Optics.
If it still bothers you, there are two solutions:
1) prune the Picture on the left and right (by a few pixels, about 7 s.jeder Page) and scale it to 640x360. Then it should "look better".
2) scale to 640x352. Thus the resolution anyway MOD16 both in width and height as synonymous especially would be absolutely correct side (; assuming your material is not a real DV and DVD).

'll Rethink the whole again in peace. :)
Thanks for the help.
