suggestions for XviD final

[Jackzeripper]

hello :)

just 2 suggestions of a french newby for XviD 1.0 final
- a bitrate limiter for standalones.
- enable to save codec settings (all settings, even zone options)

And a problem : with VirtualDubMod it’s sometimes very hard to append segment of same XviD encoding (exemple : append 2 parts of the same movie made with exactly the same settings). And much harder with different movies with same settings (same resolution, same sound at the same frequency), same type of frame (P, I, B). Is there a solution ?


Good work and many many many thanks for the job allready done and for this wonderfull codec !!!

Yeah we all would like to see this feature (VBV) in XviD - it's been discussed here (http://forum.doom9.org/showthread.php?s=&threadid=74251).enable to save codec settings (all settings, even zone options)
Cannot hurt :D

What I'd really like to see in XviD 1.0 Final is a Top Field First checkbox for interlaced encoding, so there would be no need for workarounds that convert TFF material to BFF.

Yes, and a "save results from the status window" function !!!

Already possible. Use the registry. http://forum.doom9.org/showthread.php?s=&postid=465198#post465198

Hi-

I'm with Soulhunter. I'd like to be able to save the results of the XviD Status Window. Although you can get and save those by running DebugView, it's no longer possible to keep an eye on the over/underflows, and for me, that's even more important.

yeah ! I still have to implement it by the way :D

Somebody coded a "make screenshot from status window after encoding is finished" feature in XviD, PM Sharro (or visit us at #xvid @ irc.freenode.net) for details.

Excuse me for forgetting or name (or do you use a different nick on IRC?). I try to remember the nicks of the regulars.

I had this problem, too. I found out, that BITMAPINFOHEADER.biBitCount of the videostream of the .AVI has in most cases the value 16 and somtimes the value 24. If there are different values VirtualDub refuses to append the file, because the videoformats are not the same. I patched this value with an HexEditor and had no problems in appending the file and playing the result.

I only used Koepi-XviD-RC4. All files created with latest version of VirtualDub only.

So this is either a bug in XviD or in VirtualDub.

vdub(mod) > 1.5.4 is quite buggy as mentioned in the faq.

I think what needs some serious work is the GUI. You should be able to get to all options from the one screen. All it needs is tabs up the top going to the different options.

And also the ability to save codec settings would come in handy.

Yep custom profiles would be nice.

Hi !

An option that could be interresting is the possibility to *pause* the encoding process.
Maybe you think it is useless, but I have a poor computer (AMD @ 800Mhz) so when I encode I quite can't do anything else. If I want to do something that ask for CPU for only 2 minutes for example, it could be cool for me too pause the compression (reducing the thread priority mostly didn't solve the problem).
And another pretty option that I wanted (if possible, i'm not sure at all) is the possibility to save the current encoding process in order to restart it later. i.e. in order to turn the computer off and later on to continue the encoding.
I know these options are not very important, but I think the first option is quite quick to add.
ATM, I test the XVID RC4 (Koepi bin) and if I have other suggestions, I will post again.

PS. Sorry for my poor english...
If I have time the next year, I will maybe contribute to the developpement of XViD...(I hope I'll have time)

That really has nothing to do with the codec itself but the program doing the encoding. So there's really no way that the xvid developers can help you there.

[Blue_MiSfit]

if you are running an NT based os (win2k or xp), then you can simply change the process priority for the encoder you are using (vdub, flask, etc...)

Just ctrl+alt+del, and in the processes tab, right click on whatever encoding app you are using and set the priority to below normal or low. This will force your comp to let other apps get priority.

I do this all the time - its the ONLY way to get any work done while you are crunching away on DVDs ;)

I've only used XP and Server 2003 recently, but when I am encoding I open the status window in vdubmod and that gives me an option to change the process priority right there. It may not be available on 98/ME, but if it is... well, there's your answer. :)

Doesn't really matter what OS you run you can do that in all versions of vdub in all versions of Windows.

I have a small request for future versions of XviD, if it is at all possible, I would like to see "Use chroma motion" from "Advanced Options..." be moved to "Zone Options..."

This should make possible greyscale encoding the option to uncheck both use chroma motion and uncheck chroma optimizer enabled, since chroma has
nothing to do with greyscale, yes?

I found when I added a zone for greyscale encoding, I could not uncheck 'use chroma motion' in the advanced options without that effecting the entire encode.

Best wishes.

[Prettz]

How about moving the b-frame offset and ratio to the zone options? Or would that be impossible with the current size prediction code?

[Heini011]

i wish to set the filesize for the second pass relative to the size of the first-pass. (for example: second pass 15 % under first pass)

that would be useful in virtualdobmod job-chain, where the final size of the first pass is not yet knowing. (and burning several films on dvd, where space is not the problem)

greetings, Heini011.
