Frame Size conversion Quick-CHART

[currysteph]

Hey guys, Sorry for this but this forum doenst keep paragraph formatting so everything is all run together...... I hope I'm not over simplifying this, and I realize there are various variables involved in figuring out proper frame sizes etc... But here's my deal and what I'm hoping someone can help with. Im looking for a quick reference guide to convert up or down in frame size. I use Any Video Converter to re-encode video files....mainly to get a smaller file size and to keep the quality reasonable. A lot of times I get, what I call, oddball frame sizes. Such as 816x462 or 1280x544 etc... And as you can image that when you want to re-encode if you dont have the correct final frame size (aspect ratio) selected you'll get squished video or black lines along the top and bottom, blah blah blah. SO, Im wondering if anyone has a quick reference chart that enables you to select the proper frame size so you dont get the above mentioned problems AND you dont have to do any math. Example: (dont know if their correct...im just guessing for example purposes) If you have a 1920x1080 orig video file then you can safely re-encode down to 1280x720 = 720x576 = 640x480 = 480 x 320 . . . . . The Frame sizes that Any Video Converter allows are: 1920x1080 1440x1080 1280x720 1080x720 720x576 720x480 640x480 512x384 480x576 480x480 480x272 368x208 352x288 352x240 320x240 220x176 176x144 160x112 thanks for any help Steph

No , not with any accuracy - because the frame dimensions don't necessarily take into account the actual picture contents (it might be letterboxed or pillarboxed) , or aspect ratio.

Sometimes you might want to crop (e.g. device compatibilty like blu-ray players), sometimes you don't want to crop

e.g. "1920x1080" doesn't indicate anything about the picture . If it was 16:9 contents, the full frame would be used. But if it was a 2.35:1 movie (e.g. from a blu-ray source), it would be letterboxed and you might crop to 1920x816 then encode to 1280x544

But if you started with 1280x544 - that is almost always is 2.35:1, with 1:1 square pixels, but cropped. So you could resize propotionally

So you have to examine each on a case by case basis
