Apparently 6.1.0 has a faulty h264 codec. 6.0.4 works for me, but for some it doesn’t.

i did follow your steps. (thanks a lot btw, the quality is really great), but youtube says it can’t process it….(saved .avi and .mkv…tried both)….did i miss something?”

YouTube should’ve no problem processing .avi. But how you managed to save .mkv with VirtualDub is beyond me, since VirtualDub doesn’t support anything other than .avi .

Try the newest VirtualDub 1.9.8″

I’m having VirtualDub 1.9.9 and having the same problem as Utzu is…
Any help?
Thank you

PS: Otherwise great tutorial, videos are awesome!

But if I already have the best quality possible on Youtube, it’s fine.

25 looks better because it’s about the middle. 1 looks even better, because 1 is the BEST quality.

And why are you using sharpening? If you record in 1440*900 then you don’t need to sharpen anything, since resizing from 1440*900 to 1280*720 doesn’t “lose” any quality.

If you were to record in half-resolution, meaning 720*450, then and only then, in my opinion, should you use the sharpening filter if you resize from 720*450 to 1280*720, because UPSCALING, that’s what it’s called, is always linked with loss of quality.

But you’re not UPSCALING, you’re downscaling from 1440*900 to 1280*720. You actually “put in more quality” this way.

Let me try to explain it. For example in 1440(*900) to 1280(*720), looking at the width, you have 160 (1440-1280) pixels worth of redundant information which can be used any way you see fit. Whereas in 720(*450) to 1280(*720) you’re actually MISSING 560 (720-1280) pixels worth of information which have to be interpolated (equals loss of quality) by algorithms.

All you have to do with your 1440*900 raw footage is resize DOWN to 1280×720, move the slider to your convenient quality (I’d recommend 23-25), use the VirtualDub settings I provided and that’s it.

Ultimately YouTube WILL lower the quality of your video, even if you upload your videos in the best possible quality there is. There’s nothing you can do about it. It’s YouTube fault, because they re-encode the whole video with their own settings.

51 gave me a strange video: http://www.youtube.com/watch?v=Bd8DMb__Rxg

However I didn’t notice much difference between 25: http://www.youtube.com/watch?v=K-lNDp6PDfM

and 1: http://www.youtube.com/watch?v=6AVsRDt_Fc8

Then I tested the sharpening by 64 filter and I noticed a difference between quality slider to 25: http://www.youtube.com/watch?v=xeguo4v5MW4

and 1: http://www.youtube.com/watch?v=HWHbQwnus8I

The sharpening seems to improve some graphics but also decreases others which look more blurred than without sharpening.

Quickly looking at these videos, would you have any other ideas of Virtual Dub settings that could give me a better quality ? (at the moment I only record this game with these resolution/graphic settings)

To get 1080p you need to change the 1280 and 720 into 1920 and 1080. But because you are recording in 1440*900 it would mean quality-LOSS to go to 1920x1080p. You’ll have to expirement again with the slider and the sharpen filter. Section “Upscaling and Sharpening”.

The K-Lite Mega Codec Pack didn’ t show me the codecs needed in the options settings so I downloaded each separately.

The first time I clicked on “save as AVI” it didn’t work well: it took a second to get the file and it wasn’t readable by VLC. I don’t know what happened but I tried again and it worked.

Then the first time I tried to upload on Youtube it gave me an unknown error message, second try it worked.

So thank you again I’m now able to put some vids on Youtube

Do you know how I could change the settings to get a better quality video on Youtube ? (I already have 720p but maybe better 720p or 1080p could be possible)

I record the game with fraps in 1440*900 resolution and I don’t mind about the time needed if I can get better quality.

As for your question about how to merge 3 files into 1: http://www.youtube.com/watch?v=I9eM7ikdwjU !
