View Full Version : Resize before or during lossy conversion?

I record the new Family Guy for a friend every week and then edit out the commercials with vdub, save as huffyuv, and then transcode to 1128kbps WMV9.

My question is, is it better to resize/crop via filter when converting to huffyuv, then transcode, or is it better to let Windows Media Encoder handle the resizing?

Resize when converting to huffy... will make the WMV encoding quicker.

Editing/resizing with AVISynth on the fly would speed the whole thing up even more.

I'm not sure what celtic_druid wanted to say, but my opinion is not to save to huffy at all unless your avs script is quite heavy. Decoding huffy takes quite a lot of power, and even for 2-pass encode with x264 that contains IVTC and denoisers it's usually faster to encode directly without going to lossless.

I would love to pretend that I understood all of that, but honestly I'm somewhat noobish at this stuff. I'm doing well just to be able to get editing and transcoding all done in vdubmod. I don't really know how to use AVS and my only experience with it is through AutoGK.

I've stopped using WMEnc anyway, so I should probably start a diff thread for my new questions. Thanks to those who responded :)
