Xvid-->svcd question

[Xvidiot]

Ive encoded quite a few divx and Xvid movies without problems using the guides on this site,but my problem is the last few movies ive tried to encode play a bit jerky on my dvd player(nothing terrible)every 2 min or less the picture seems to jump or kind of stutter.
Anyone have an idea what may be causing this?didnt have this problem with any other divx or Xvid movies?

Maybe i just need the latest Xvid codec

any insight or help would be great!

[Xvidiot]

Someone must be able to help me?
Ive tried 3 different movies and they all use Xvid and when i encoded them to svcd they seem to be jerky almost like theyre missing a frame?

Ive uninstalled and reinstalled all codecs and programs and it still seems to be doing the same output?

this is drivin me crazy can anyone help?

Look up your dvd player and make sure that the bitrate you're using isn't too high for your player. I had the same thing with my player, I can only use 1850kb/s.

It sounds like framerate problem - have you made sure that your selected template corresponds to your XviD framerate? If it doesn't, you need to convert your framerate using this guide before loading it into TMPGEnc.

Thanks guys

ive looked up my dvd player and it has no max bitrate

0kewl:most of the movies ive converted are 23.976fps what is the proper template for this type of framerate.

ive been using NTSC FILM SVCD template
maybe im wrong

I suggest using DVD2SVCD instead of TMPGEnc, i have been using dvd2svcd for all my xvids and divxs and they come out really good. This is a good guide on how to encode a divx/xvid to svcd using dvd2svcd: http://vcdhelp.com/forum/userguides/111846.php .

havin the same probs Xvidiot. If i click on 'do not frame rate conversion' in tmpge the video runs smooth but the audio is out. Running out of ideas. anyone else with some suggestions???

I think I've solved the problem folks. I have been having the same problems with Xvid's and DivX avi's. I read somewhere that the reason they are jerky once encoded is because of the codec's themselves. The article I read said that Xvid's and DivX's had a variable framerate (even though in properties it will tell you a specific framerate) and sometimes frames could be duplicated or blended with another frame to allow the variable framerate, but this cause's problems when you encode. Unless you Frameserve. This is how I encode and they playback on my Philips DVD 634 as smooth as a very smooth thing.

1. Load the avi into Virtual dub and extract the audio to wav. If you get a message about 'uncompatable audio stream vbr audio' when you load the avi ensure that you choose full processing mode under the audio tab, not direct stream copy.

2. Once you have extracted your audio choose no audio under the audio tab, and choose full processing mode under the video tab. You do not need to do anything else to your avi as TMPGenc will do all the resizing and encoding. Goto file and choose start frameserver. Click ok in the box that comes up, it will then ask you where you want to save your frameserver. Save it as what ever you want but ensure to type '.vdr' after your filename. When you click Save the frameserver box will open up, just leave that as it will start automatically once you start encoding in TMPGenc.

3. Open TMPGenc for the Video Source you need to browse to where you saved the frameserver file name .vdr and choose that as your video source. It may not show up so you might have choose show all files. Now adjust your template settings and press Start to start the encoding. When you press Start the Frameserver should immediately start serving frames to TMPGenc.

I always choose ES(Video Only) in TMPGenc, this will output the encoded file as a '.m2v' file which can be muxed together with your audio which you should always encode separetly. I use Headac3He for that. You will find a link to it in the tools section. And I always us BBMpeg to mux the video and audio together.

I hope this helps any of you having trouble. I was tearing my hair out trying to solve this problem. I am now getting some very good svcd's using the above way of encoding. I would post a copy of my TMPGenc template I have made for svcd's, but I don't know how yet.

Any questions just ask and I'll help if I can.

hi dobbs thanks for the reply but cant get past the 1st stage. virt dub wont allow me extract the wav on full processing mode although it will allow direct stream copy mode. the error message i get is

'the requested audio compression is not compatible with the input format. check that the sampling rate and channel count of the input match those of the requested format.'

can you shine any light on this???

[Dobbs2010]

Its sounds like you have AC3 soundtrack.

After you have loaded the avi into virtualdub look under file and choose file information, if it says 2 or 5 channels under audio and it says compression unkown, this means the soundtrack is AC3.

You can direct stream copy to a wav file, but you must then rename the .wav file to .ac3. Look in the tools section for a tool called AC3fix. You must run the .ac3 file through AC3fix as virtualdub creates errors in the file. You can then run your .ac3 file through Headac3he and convert it to .mp2 format.

In Headac3he always choose mp2 output and resample to 44.1khz. Under options press the 2ch button. Press options again, choose CBR what ever bitrate you want and choose Stereo for you channel mode.

Hope this helps.

cheers for the reply but still no joy Been doing me head in all day.

It does seem to be an ac3 soundtrack i.e. 2 channels and compression unknown(tag2000).

So downloaded ac3fix but couldnt get it to work so renamed wav in dos. when loaded it into headache says possible sources last frame incomplete or corrupt stream.

Anyways follow the steps but when i get to start it says unable to load mp2enc.dll. tried to d/l file from darks site but same message appears.

I'm crackin up but still determind to sort this file

[Antz]

here goes..... iv'e had all these problems listed above. i agree frame serving solved it, but have still noticed that smooth camera actions (like credits etc) still stutter occationaliy. when frameserving i dont extract the audio anymore as i found virtualdub made the voices slightly high pitched? i use an external tool called 'SSRC' which is supported by tmpgenc. simply install it, go to options (on tmpgenc), enviromental settings, audio engine, sample frequency converter and click 'external program'. you can then browse and select the SSRC.exe you've enstalled. encode your film (movie, i'm english ) with the frameserve virtualdub file as the video source and the actual xvid as the audio source. what ssrc will then do is extract the audio as a tempery WAV file, covert it to 44100hz and use it as the audio source. this should fix the problem and result in a much better audio quality.

Hope this helps!

[wellskint]

sorry to be a pain but tmpge says it doesnt support .vdr

heres what i do load virt dub and xvid file, then start frame serving save name.vdr then where.

open tmpge and browse video source file then error message says cannot open or unsupported...

tried that ssrc and worked ok but audio still out of sync if 'do not frame rate conversion' is ticked. picture jerky if not ticked.

still aint giving up the ghost folks so any more help or suggestions more than appreciated

[woody2k2]

tmpgenc also tells me i cant use teh VDR because its unsupported any ideas?

[Antz]

k, i'll try again. that unsupported thing has also happened to me with the 'windtalkers fim' (most films are accepted when servin to tmpgenc in my experience). open the xvid and select direct stream copy for both video and audio, file save as AVI. open the new avi u just made and start frame server. tmpgenc will definately read the file, i've just used that method to encode windtalkers.

[wellskint]

nope tmpge still aint havin it... goin to bed. cheers anyways

[Antz]

It does work!!! Open up tmpgenc, select options, environmental settings, and up the priority of direct show to a 2 or 3.

[wellskint]

whoa there antz, calm down calm down . done what you said but still wouldnt have it until installed avi handler/client and mscr.dll.

Cheers kid it runs as smooth as fonz 8) out of happy days and these are happy days.

nice one again

You're not. NTSC Film is the proper template for 23.976 fps, just make sure that the source of your last few movies (the ones with jerky playback) had this framerate. If not, use the framerate conversion guide before encoding to Mpeg1/2 (if the source is 25 fps) OR the 3:2 pulldown option in TMPGEnc's Advanced Settings (if the source is 29.970 fps).
