Indeed...

More competition between chip-set manufacturers would help push prices down.... Especially as Sigma have cornered this sector of the market for a couple of years now!

Is that single sigma chip still the only HD game in town?
That would explain why HD divx players are still $250+
Maybe the others are focusing on developing AVC/h264 decoding hardware to grab some of the bluray/hddvd market.

Sort-of on topic for this thread, I take that it's impossible to do any kind of near-lossless conversion of h264 to mpeg4-part2, even if the more advanced options of part10 are not being used? I wonder if an optimized process could be written to keep the re-encoding as lossless as possible? What I mean is that an xvid/divx stream that is using qpel and gmc has to be fairly close to the spec of avc/h264, no? I guess I don't know enough to ask the question properly...

The quantization step is totally incompatible, and that's where most of the quality gets lost. You might be able to reuse motion vectors, since they're post-quantization in AVC instead of pre (like other mpegs), which is good, a lot of time gets wasted there. Hmm, but AVC has more motion vector modes, some of which are incompatible, but at least it's a head start. And it would be quite complex, rearranging b-refs into... something. Overall it's not worth the effort.

Ah I suspected my ignorance was making it sound too easy,
thanks for the clarification foxyshadis...

SeeMoreDigital · 10th November 2006, 21:11

You know, I can't help feeling there are many members missing out on this great little application... with it being located in this section of the forum 'n all

ReinerSchweinlin · 10th November 2006, 21:16

Yes, I agree. Sometimes I even get confused where to get the binaries, the PR-Part could be imrpoved to give this great Prog the attention it deserves.

_ck_ · 11th November 2006, 07:36

Anyone with a DVP642 should be aware of it.
Either that or they are cursing half of their disc burns that don't work or they are wastefully doing complete re-encodes.

afaik mp4box also drops delay frames (its full of workarounds and fixes for avi and vfw)

You can try out this version, it should look better. It looks ugly with normal size fonts though

I looked at it a bit but it seemed difficult. I might be able to figure it out if I focused on it enough, I don't know.

Just wanted to let you know the normal fonts version does indeed solve the issue here. I've seen other apps that can adjust the window size automagically if the system is set to use large fonts but I couldn't begin to suggest how it's done.

Allowing the window to resize might be a workaround?

I screwed up and used a FourCC code that some of the Divx tools don't like. I need to change it without having to re-encode a bunch of files, if at all possible.

Thought this tool would do it, but I don't see any way to modify the FourCC code with it (can read it out in the Info screen, but that doesn't help).

Am I missing something with MPEG4Modifier, or is there a different tool that will do the trick?

ReinerSchweinlin · 21st December 2006, 02:10

Try NIcs FourCC Changer, its inkluded in KOEPIs XVID Build an sure is available somewhere on the net, maybe dvdrhelp.com? doom9 download-sektion? google it

Thanks

Now I just have to find the program...

Hi !
I have a lot of files that won't open in MPEG4-Modifier giving something like "This is not valid MPEG-4 video (startcode not found on the beginning of the frame). Codec DIV3" or "This is not valid MPEG-4 video (startcode not found on the beginning of the frame). CodecMP43".
However both WMP and other soft players as well as my hardware based players (one MTK and one Sigma EM8620 based) play the file fine.
No other utility gives an error ...
Can you please explain why it happens ? If needed I can provide samples ...

foxyshadis · 31st December 2006, 13:15

Microsoft MPEG-4 and DivX ;-) 3.11 aren't actually MPEG-4, they're based on an early draft, so you'll always get that message. You have to translate them into real MPEG-4 with another tool to use this one. YAMB/MP4box might be able to do it, but then you don't have an avi anymore.

Kurtnoise · 31st December 2006, 14:09

Nope MP4Box doesn't support that files but there is a ffmpeg build somewhere in this forum to convert this kind of files losslessly...

I can upload it if necessary.

Lord_KiRon · 31st December 2006, 15:00

Well the tool that REALLY converts DivX 3.11 or old ASF to MPEG-4 compliant LOSSLESSLY would be really welcome , I never knew such tool exists.

About my post - I still think MPEG-4 Mod. should hand this files at least for changing AR.

1.4.4 released. Fixes problem where DivX subtitles were broken after being run through MPEG4 Modifier, added *.divx extension to the file dialogs, and provides a default filename when saving (same as the source filename).
