I'd like some help about video encoding

see, I am working on a longplay of super mario all-stars, and I use the lagarith codec to encode the videos as I record them, but youtube doesn't handle that codec somehow, and now I have to convert the videos if I'm to ever post them on youtube, but I had no idea which one would be the best for that. my main concern is that plenty of my earlier videos have sound desync, which is impossibly grating to me (and plenty others I assume), and I'd like to know how to encode a video without sound desync happening.

would anyone here be willing to give me some tips?

 

What ardent you encoding in Prores422 or H264?

You should have no sync problems and they'll work great with YouTube.

 

I was encoding in plain mpeg4. then I learnt about lagarith and I thought it'd be fine but youtube won't process the videos.

what's prores422, if I may ask?

 

lagarith is an excellent lossless codec but as you say it's no good for YouTube. What I do is encode in lagarith then convert the file to F4V format (HD quality Flash based video) which then gets uploaded to YouTube. The plus side to this is that the file sizes are smaller so it uploads quicker and stops YouTube giving you a size limit. Also it should stop You Tube destroying your video by re-encoding it to their lower standards. They will still re-encode it but it's quicker and losses less quality.

Encoding is a pain in the ASS.

I have yet to find a way to downsize a video file without making it look like crap. The source is a 60FPS 2D game trailer and making it into mp4/mov fucks up everything, leaving a ghost trail behind most objects, it's a nightmare.

 

What are you using to capture and what are you using to squeeze?

 

May I ask where or how to get that codec? I did a google search but the only results I get are garbage. either I get directshow filters that I gotta pay for, or I get flash video players which is entirely useless to me.

 

A/V going out of sync seems to depend on both the container as well as the player; in general it's a good idea to try to avoid variable bitrate audio.

If you want to be really, really sure you get the best bang for your buck, try using HuffYUV for video (lossless compression) w/ PCM (lossless, uncompressed) audio. The resulting file is gonna be huge, but that way YouTube will have the best possible source material to squeeze into their crappy-ass flv files.
The second best choice imo would be XviD w/ a very high bitrate (way above what would be sensible for dvdrips etc) and constant-bitrate MP3 (or better yet OGG Vorbis, dunno if YT supports that though) audio - a decent compromise if you're constrained by hdd space or bandwidth.
YT's encoding process will still make it look worse in any case, but that's something you simply can't avoid.

 

It's not a free codec. I usd Adobe media encoder to make the files. I'm sure with some searching you could find that software for free. I bought mine as part of the Adob CS suit.

...oh!

oh well. anyway, I've started using a divx mp4 codec, and at the best quality settings, I was able to record the first part of my super mario all-stars longplay (I recorded myself going through super mario bros), and not get any kind of sound desync at all, and the entire video is almost a hour long.

I had made a test video before with mortal kombat 3, and it went fine too. I guess I'm getting lucky.

 

You can also export to h264. YouTube supports it, and there're tons of free programs to encode in h264. Personally I use QuickTime Pro (not free).

Also, this really ought to be in off-topic.

 

note: if you want to capture h264 in realtime, make sure you have a dual core cpu atleast.....

in other news... just encode to mpeg2 my friend, it's a decent codec , you won't loose much quality if you encode at 10 or so.... the file size will also be of decent enough size to upload and you wont have to reencode the looseless one in order to upload to youtube... all in all it's a very known codec.

 

Are you playing on an emu or hard?

 

Imagine a world where youtube didn't force you to transcode and users had the option of downloading the original file you uploaded.:crying:

Unfortunately as has been said I think your best option for quality would be huffyhuv video with pcm wav for the audio. But thats going to be a big file if you have 1hr of video.

 

i believe divx works but it may be mor trouble than its worth.
anyway they have tons and tons of converters to choose from and i also believe youtube list the videos file it likes .

 

emu. I know, it's bad.

 

sorry for the late reply,

I am using FRAPS to capture a video off my computer's framebuffer

and then I use a lame program called Any Video Converter.

To be honest I find it quite limited in its variety of output formats. The results fail to impress but I'd rather seek advice than risk infection.

 

No, it's just my knowledge of capturing is limited to external sources :redface:

 

Terrible idea. Far easier to download and reupload.

Suddenly youtube is filled with thousands of the same viral video.

 

It's pretty easy to do that already.
