With 4:3 videos, I have noticed that I sometimes need to change pixel type to Square Pixel, and on other occasions leave it on default settings, I think this is down to how the MKVs were originally encoded onto the disc. On some occasions, I forgot to change the pixel type and found that my encodes have also put black bars on the top and bottom, which has got me thinking about the Crop tool.
I am upscaling PAL 4:3 videos to 16:9. Is there any reason I should or should not bother cropping them?
Also, when I select Crop, the software reverts from HD to SD. Should it do this and do I need to select Second Enhancement to enable HD again?
The crop tool can be used if you want to select a portion of the frame rather than the entire thing, cropping happens before the output resolution is set. In the crop tool you can select a 4:3 or 16:9 aspect ratio.
If you want the entire clip to be processed, you will have the option to apply black bars, which won’t remove anything from the frame, or crop to fill which will remove the top and bottom of the frame when going from 4:3 to 16:9.
I am trying to convert 4:3 SD video to 1080 HD. I can’t seem to get the Crop to work properly. It’s cutting of part of the subject’s head. It’s difficult to get the manual crop where I want it. It seems to get stuck partly off frame to one side but does it override the Crop setting under Pixel Type?
You have physically 4:3 squeesed content, made to “width-strecht” to 16:9 when play? may check here I wrote something about that.
Forget TVAI crop when you can’t achieve desired result then use for example Virtualdub2, where you can letterbox free scale/stretch first and then crop.
