I have a question for those involved in video encoding. Many emulators support advanced filters like HQ2X, SuperEagle etc, why nobody uses them?

We used a HQx filter for some time, but then community disliked it.

Do you mean downloadable encodes, or streaming (YouTube and others)? Downloadable videos are captured at original resolution, so there is nothing to filter (filters are only applicable when you scale).

http://research.microsoft.com/en-us/um/people/kopf/pixelart/supplementary/multi_comparison.html Pixels are cool. For modest upscaling, pointresize looks the best. For crazy upscaling the pixels can cause eyebleed. Something with the shape of hq4x and the colors of EPX might be ok, but IMO none of the available choices are better than point, and most are worse.

I like bilinear filtering or the "TV emulation" filters when playing SSNES.

Good link, but their results are in dire need of improvements, it tends to oversmooth things and make freestanding areas (such as Yoshi's scales) look like they are flooating way of the character.

1) Is it possible to use Virtualdub to create transitions from random encounter to random encounter the way HCBailly does in this video? http://www.youtube.com/watch?v=vGoi1tLjpCE 2) Is there any way to improve my method of making videos as far as video games go? So far it's this... First, I use "Full Frames (Uncompressed)" make all the edits and stuff I want to do in Virtualdub. Then, save the AVI, import it into Windows Movie Maker, make my commentary according to what's on the AVI, then publish the commentary as a movie, then insert the commentary into the AVI saved in Virtualdub, then finally upload it to Youtube. Is there anything more I can do to make my videos look even better?

Never use full frames when dumping. The videos are way too large and often times desyncs occur between sound and video. I'd recommend installing a lossless codec like Lagarith, and using that to capture the raw dump.

I use full frames while dumping. Yes, it does take up a lot of space. No, I don't get time desyncs.

Not in VDub. You should be able to do this using Windows Movie Maker if you are still using that. Otherwise, you will need more of a full video editor like WMM to do effects.

I know that you can do that in Windows Movie Maker, but I'm trying to avoid using that because then I'd have to publish the movie in WMM, right? But then the quality isn't as high as it would be if I used Vdub, or at least I don't know how to get it in better quality. Do you have any suggestions?

Well, you can check out the Encoding Guide, which basically details how videos are encoded for this site. In a nutshell, we use AviSynth script files to do things like add subtitles or size the video up into an HD resolution. You can load AviSynth files with VirtualDub to see how it looks. Then use x264 to do the actual encoding (again feeding it the script file). AviSynth has lots of plugins. It looks like there is a TransAll plugin which includes transition effects like the one you showed above. You'd have to download it and configure it to see how it works, but it seems possible to use. http://avisynth.org/warpenterprises/

Okey doke then. I'll try all this out tomorrow, then I'll report back with the results, alright? Thanks for all the help!

So, question, how do I use the AVISynth plugins? I'm trying out the Encoding Guide, and so far, I've found it extremely helpful in terms of video and audio dumping, but it doesn't say anything about how to operate any other AVISynth plugins other than what's listed in the guide. And I'm not faulting them for that, I'm just saying, I don't need subtitles. Would you happen to know how to use it? If not, where could I go to figure it out?

Do you know how to make videos high definition in virtualdub? Eg. using the 'resize' filter or something else. I'm unsure how to make it nice and sharp as most of the videos are here.

Use Nearest neighbour method and that's it.

Or use Avisynth's ConvertToRGB32.PointResize.

BTW, lossless dumping from emulator is necessary for nice resize result.

How did you dump the video from emulator? What codec?

Use true lossless codecs without bugs: CamStudio codec or Lagarith. http://tasvideos.org/EncodingGuide/Requirements.html

Ah, I forgot to mention. If you dump losslessly, then drag to virtualdub and resize - use some lossy codec with best settings inside VD. I use Xvid for non-tasvideos YT uploads. http://www.youtube.com/watch?v=LFBh6UngPUg&list=PL514DD07B333CE50D Why don't you try official HD encoding method really used there?
