Just curious if what I’m doing is a good general workflow or…are there alternatives?
When I encode standard definition clips for computer playback, web or CDROM, I usually do a proportional scale down, depending on the job specifications. For example: Master video is PAL 720 x 576 with a proportional scale down to the following resolutions:
75% of source 540 x 432
50% of source 360 x 288
25% of source 180 x 144
I guess it’s the same workflow for HD clips. So
1280 x 720
75% of source 960 x 540
50% of source 640 x 360
25% of source 320 x 180
I guess I can also calculate based off aspect ratio –
Multiply the desired height or width by 1.778 or .5625 (for 16:9 material)
What’s the question???
Hmmm…Does the above sound logical? Can I be doing something wrong?
