i'm encoding a video for the castle of illusion run, i've got the quality to be satisfatory with the final video being 150 mb big, but sometimes during playback the image freezes or starts to choke whil the audio continues normally, and then 3 or 4 seconds later the video (now delayed) skips to where the sound currently is (which is where it should be if it werent for the earlier freezing/ delay). i've tried several things to fix it, some faqs say that the player needs to be set to not use overlaying, and turning it off on windows media player really made the freezing to occur not that often, but it still happens about 6 times during the 19 minutes long movie. the frames that seem to be lost are actually there, if i scroll the video i might get lucky that it wont freeze on the same moment that had previously frozen. my settings in virtuadub are pretty much the same as in the avi making guide from this site, the difference being that i encoded the audio along with the video all in virtuadub (i didnt use lame or nandub). the audio is set to interleave every 60 frames, using a vbr mp3 encoding. i've tried doing a single pass encode for the video and 2 pass encoding, but both showed the same problem. a video of 210 mb also had the same problem. i dont know if it can be fixed, or what is the problem, the quality is good enough, the video would be done processing if it werent for that issue... can aybody help? PS.: btw, i added the info at start, i cut the 2 seconds of the raw captured video (those 2 seconds had no sound at all) and put 1 second of advertising this site and 1 second of the run statistics, the only thing that was lost on the 2 seconds that were cut is the SEGA logo and black screens.

Hmm.. I had a similar problem a while back when I encoded Xvid with packet bitstream. Uncheck that option and try again. Furthermore I really encourage you to cut out the wav file and compress it with lame vbr at about 76kbit or something. Also.. Try using virtual dub mod instead of the official release. I found that better when dealing with variable bitrate audio. Just hit "NO" when asking if it should encode with CBR in Vdub mod. Hope this helps solving the problem.

cool, that seems to have fixed it. and yea encoding audio on lame put it to the correct size of about 9 mb, while virtuadub was making the audio 50 mb O_o... now my video has 106 mb, how can i start seeding it? or maybe i'll send the video to bisqwit or phil and they will set it up^^?

Great! Glad I could help. :) About the seeding I don't know. I've never done that before. I think you should be able to just open it in your torrent program and get some sort of link or torrent file from it. Then you could share the link information for people here on the forum.

To seed a new file you need to upload it to the tracker whose address is mentioned in the .torrent file (which can only be done on the tracker owner's permission) and then just launch it like if you start downloading it.

I don't like VBR in AVI, it's a hack. I always encode to CBR MP3 when encoding audio for an AVI. It works well enough, but if you want to do anything with it in VDub, you have to decode it and reencode it with CBR to prevent skewing. VDub was making the audio 50MB because it was likely writing out uncompressed audio. I always compress the audio externally with LAME, as you did, then mux it in with direct stream copy. I generally use 128kbps or higher, depending on the quality of the source (like, if I record from a cable DVR that's set to 128kbps MP2, then I'll likely use 128kbps MP3 because any better is really a waste).

i have chosen "create torrent" on bitcomet, it seems to be ready to start uploading, just need someone to start downloading? how can i give the link, or do i give you the .torrent? it says this is the tracker on the torrent properties: udp://tracker.bitcomet.net:8080/announce but i dont know what to do with it..

@LocalH - Depending on what you are recording with your 128kbps MP3 it's not a waste to set it higher. I for example can hear great diffrences between 128 and 192. It's not that hard really. Of course I would choose higher or lower bitrate depending on what I want to do with it. For an encoded speedrun I would never go higher than 96kbps since that is truly enough since we want minimalistic videos but with fair quality. But if I would make a DVD or something I would want to have highest possible quality settings, high enough to barley fit it on the disc.

Just wanted to let everyone know that on my pc ALL videos from this site have a little freezing every now and then while playing back. My pc is a pentium III 1000 mhz with 256 ram and a geforce fx5200 256mb video card. maybe the processor isn't keeping up with the compression code of xvid.

its not something big, its just a little flickering in some parts of the video (the sound keeps going) but the video stops for hmm 5 frames maybe and then jumps to where the sound is. doesnt happen often, but its not good

I occationally get the same thing, but it happens with both DivX and Xvid. I think it's the player, I use Media Player Classic, but I sometimes use Mplayer (the Windows version) and it never happens there at all. Of course, Mplayer will play anything, no matter how corrupted and useless the file is...
