Video Still looks like ass (Halp)

PS2 - Uncut Repair Sunderer Gameplay Part 2


So, after upping my bitrate to 3500 (max twitch will allow me to upload/stream at), the files directly on my hard drive look just fine, I can play them back in full screen and nothing looks pixelated or grainy.

Using Avidemux I've been pulling snippets out like the one above, after tweaking and experimenting with some things I was using the MP4 encoder that's built in and selecting 'copy' (I assume this means copy 1:1).

The raw file that this produces (if I open it back up in avidemux) looks like it scaled itself down to ~40-50% of the original resolution, but if I full screen it in a player it still 'looks' very acceptable. I can read all the text clearly, but Im confused as to why it downscaled so much in the first place and in addition why youtube cocked up its processing of the video so badly. It went from 'good in full screen at 1680x1050 to 'dear god my eyes'.

So...anyone know what video/output settings I should be using? Should I up my bit-rate even further? Why is youtube absolutely wrecking my quality, should I be using a different encoder/codec?

is my googlefu up to par caff?

You can direcly enter the new width/height and the resize algorithm or use the slider and the menu. Three resize methods are proposed :

Bilinear : Smooth a bit but easier to encode
Bicubic : Keep sharpness, harder to encode (for example leads more easily to macroblocking in SVCD)
Lanczos : Hard to describe, very sharp.
Source and destination are important. If you do DVD2Divx for example, source is 4/3 or 16/9 and destination is 1:1. The other way around for Divx2SVCD.

It is important as 4/3 has non square pixel (different for PAL and NTSC) and if you do 1:1 -> 1:1 you will end up with distorted image.

Im so-so at googlefu, but with things like this I prefer to ask the experts that I know before digging around trying to haphazardly stumble on a solution. Tonight I can fool around with some of what you suggested and see if it improves anything....

Tried messing around some more this morning, looking deeper I had the original settings

Video Output - Copy
Audio Output - Copy
Output Format - MP4v2 Muxxer

So, in theory that should be doing no encoding and copying the raw video into a file...which it appears to do (just looks half sized when I open the resulting output in the same program). Additionally, it won't let me apply a filter or configure the codec as there is none.

I tried this:
video output - Mpeg2(ff)
- Filters 16:9, 2 threads, constant quantizer
Audio - Copy
Output - AVI Muxxer

That took several minutes and pooped out something that looked completely like ass.


The first one I would think would pull the best video as Im literally telling the program to do no compression or anything, just snip the frames out into a new file, and the resulting file looks to be this way, but youtube ate it.

Here's the original that youtube chewed up... https://www.dropbox.com/s/ud5t7zc7mj95aa...oad_02.mp4

Burn that midnight oil!

burn the midnight oil
Fig. to stay up working, especially studying, late at night. (Alludes to working by the light of an oil lamp late in the night.) I have a big exam tomorrow so I'll be burning the midnight oil tonight. If you burn the midnight oil night after night, you'll probably become ill.
