mp4-avi conversion help

[Deblk]

Hiya....can anybody possibly tell me from the 2 media info given below why the first one works and the 2nd does not on my blue ray dvd player? TIA

Either the player does not like AVI....period.....or it is the completely unnecessary 32 bit audio in that AVI.

Ok...but they are both AVI which one works and I usually don't have a problem with AVI but as you say maybe it is the 32bit

[hech54]

I have never had a need for 32bit audio.....ever.

Ok but that was what it converted to using xviD4psp...how do I change the 32bit please?
Strange though because other AVI vids with 32bit audio play ok

It looks to me like the problem is the Profile. According to poisondeathray, most consumer devices do not support anything above L4.1. The second video is L5.0 while the first is L3.0. I would try re-encoding at L3.0 and see if that solves your problem. Does the file play on a PC?

Thanks...How do I change my profile to L3.0? Yes, plays on laptop with no problem.

Lossy audio doesn't have a bit depth. There's no such thing as 32 bit AC3 or 24 bit AC3 etc. It's just AC3. It gets decoded to a fixed bit depth so maybe MediaInfo is taking a guess as to what that's likely to be. I looked at quite a few AVIs containing MP3 and AC3 audio and MediaInfo isn't reporting a bit depth for me. Just a sample rate and bitrate (ie 48KHz, 192Kbps etc).
I don't know why MediaInfo is reporting what it's reporting but I'd be interested to know what version was used to obtain the info.

Deblk,
I'm not sure you're being given the correct advice re the Profile. It sounds like what's being referred to is h264 levels and not ASP profiles. The Xvid Home Theatre Profile, which I think pretty much any DVD player should support, looks something like this:

Video
ID : 0
Format : MPEG-4 Visual
Format profile : Advanced Simple@L5
Format settings, BVOP : 1
Format settings, QPel : No
Format settings, GMC : No warppoints
Format settings, Matrix : Default (H.263)
Muxing mode : Packed bitstream
Codec ID : XVID
Codec ID/Hint : XviD
Duration : 3mn 49s
Bit rate : 1 091 Kbps
Width : 704 pixels
Height : 384 pixels
Display aspect ratio : 1.85:1
Frame rate : 25.000 fps
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Progressive
Compression mode : Lossy
Bits/(Pixel*Frame) : 0.161
Stream size : 29.9 MiB (87%)
Writing library : XviD 1.2.1 (UTC 2008-12-04)

I'd start with trying a process of elimination. Open the problem AVI with VirtualDubMod. Set the video compression method to direct stream copy under the Video menu and save that as a new AVI. If the new version plays it's something to do with the muxing. If it doesn't, disable the audio under the Streams/Streams List menu then save just the video as a new AVI and try again. If that plays then maybe it is the audio.
Some DVD players might only be happy with the standard Default (H.263) matrix or maybe the mpeg matrix but they mightn't like a custom matrix. The info you supplied doesn't seem to specify the matrix used, hence my asking what version of MediaInfo you're using. The only other possibility I can see is there's no B Frames listed for your first AVI, but there's one specified for the second AVI. It'd have to be a very old player not to play video with a maximum of one B frame through.... I'd have thought.
Oh, and the info you posted doesn't seem to show the muxing mode either.

Deblk, if it plays on your laptop that is a good sign since there are no profile limitations on PCs. Then, I would say it is most likely the profile that is causing the problem and try that first. Although I am not ruling the audio out completely, many times both have issues. But, regarding the L5.0 setting, I have run into this exact problem myself. Setting the profile to L3.0 solved it, most set top boxes even support L4.1. Did you encode this video yourself? What software tool did you use? Otherwise, you will have to re-encode the already encoded file and that will introduce artifacts and degrade the quality. But sometimes you have no choice. Either way, you need to re-encode the video because I am not aware of a way to switch the profile after encoding. Please post back here with more details because it matters in terms of the advice you need. Lots of people prefer GUI based tools to encode video. I shy away from GUIs for command line base tools and thus I am probably not the best to provide help.

Are you sure you're not mixing up h264 levels with h263 levels and profiles? Do any h263 profiles have a level 4.1?

I'd be astounded if there's still a working DVD player to be found capable of playing AVIs that'll only play video encoded using the simple profile. The advanced simple profile has been the standard for a long time, at Level 5, mostly without GMC and qpel, which is why the Xvid Home Theatre Profiles use ASP@L5 without either.
