Avi files "Not Support Video" on dvd player?

[aelfheah]

Hi

I downloaded several files and burned them (with Imgburn) to dvd -R or +RW disk as avi files as I have before successfully.

But this time I popped the dvd disk into my dvd player (LG DVX550), the files appear as usual down the screen, but when I press play, the message "Not Support Video" comes up?

They play on my PC but not my dvd player? Why are these files any different?

You have to use gspot or mediainfo to identify the codecs used. They could be slightly different than the ones you can play. Any differences might mean you have to reencode the files to a format the player will play. You may also be able to change the fourcc headers and remux it.

You need to verify the type of files your player can play and confirm the ones that don't play meet those requirements.

Also if they are high definition files virtually all dvd players only play standard definition video files. - A bluray player should be able to handle it assuming it plays that file extension and codec.

You need to provide more detail for more assistance.

Thanks, here is a screenshot of Gspot's result;-



The rest of your post sounded a bit more technical than I'm used to!!

aelfheah,
The only thing that sticks out from gspot is the "GMC" (Global Motion Compensation) box being lit up in green. Several years ago it was a somewhat common practice for people to encode with the GMC option turned on because people encoded for playback on computers, which had no problem with playing back GMC-encoded files. When standalone players came along, though, it caused problems due to the low-powered chips being unable to decode the files. Most would just say "Video not supported", although some would attempt to play the file and then glitch when they encountered certain scenes. As a result, you rarely see files these days that are encoded with GMC.

GMC was always pretty useless, unless you had a scene where, for instance, a camera was panning while being raised/lowered, rotated on its axis, and zoomed; then it might save you a few bits. I'm hazy on the details, there are some good discussions on doom9 about it, though, if you're interested.

If that is indeed your problem, the only cure that I know of is to re-encode. If you're new to re-encoding files, type: recode avi gmc into Videohelp's search box and it'll point you to some guides.

I had to re-encode many such files back in the day, though it's been a few years. There will, of course, be a slight quality loss, but if done right, there's a good chance you won't even notice it.

Thanks a million, squash!

I'll look at doing this then.

IMO MediaInfo is a clearer program for posting medio details as you can do so as text and it's a bit easier to read. But the info given is all correct about the way avi files are encoded. Sometimes "packed files" can cause problems but mainly on some PVR's. There are a number of "Swiss Army Knife" style programs out there to sort out these problems. AviDemux has saved me a more than a few times..

[aelfheah]

Ok, so is Avidemux or MediaInfo better or easier to use for this purpose than Virtualdub?

Avirecomp is your solution. It reencodes and removes special features like GMC.

[aelfheah]

Thanks, do any of them recomp in batch mode?

[aelfheah]

Anyone advise if any programs that convert numerous files simultaneously?

I just tried avirecomp but it doesn't recognise my avi files as avi? I converted them from mkv to divx yesterday?

[drjtech]

I converted them from mkv to divx yesterday?

That's a pretty important bit of information to have overlooked. Do you still have the mkv source files? What did you use to convert to avi? Your best bet may be to start over with the mkv files and be sure to not select GMC.

[aelfheah]

Yes I still have the mkv files, I used Quick Media Converter (it accepts multiple files to convert at one go) to avi - I tried xvid and divx but my LG DVX550 dvd player doesn't recognise either?

Should I download one of the above programs, I remember them being fiddly?
