Re: The Nokia Internet Tablet Video Converter
 
As a Linux user I think it's perfectly OK that this video converter application is Windows only. Well, it's probably also good to target OS X. As has been said by others already, on Linux we're well covered. We've got lots of ways to convert our videos. What this Nokia application is doing is easing the access to the Nokia tablets for Windows (and OS X, eventually) users. This can only be good for the Nokia Internet Tablet community because it can only increase the awareness of the product.

Yep, Flash Video is a tough one due to codec support at the OS level. Basically if WMP can't play it on your Windows machine, this app has no shot at being able to decode it. At least right now -- stay tuned for future updates.

The Nokia converter does not accept MOV files from my digital camera. Is this because MOV files are played with QuickTime instead of Windows Media Player? I think this will leave many of your intended users scratching their head???

Media Converter and MediaCoder does convert MOV files to Xvid-MP4 that play on the default 770 video player.

Yep, exactly right -- it's a Windows codec issue. We're working on how we can better solve this issue as it's not acceptable that end users have to figure this stuff out

That's the unfortunate effect of us using different codecs from those Open Source projects.

vbrilon,

You have no idea how much we appreciate developers stepping in to exchange a few words here. It really generates a lot of goodwill, and, unfortunately, doesn't happen often enough.

I'm an OS X user, but I've recommended this application to a number of my Window's using NIT converts and its certainly saved me a lot of trouble trying to explain the finer points of video encoding to them. ;)

Thanks for everything!

This thing is awesome. Is there a way to convert movies (Talladega Nights) in this player? Do I need to use another program to convert it to an MPG 1st and then convert it using the Tablet Video Converter?

I've just downloaded and tried this and want to say thanks to the Nokia team that put this together.

This is no knock on the developers who've offered earlier versions of the same, and yep, it's windoze only (so far). And, while I am sure that it won't wash the dishes my kitchen sink (or convert every type of video known to man), it is a fine development and I am grateful for it. Thanks.

Well, I booted XP and gave it a shot. The input file was a 720Mb DivX/Xvid copy of a Star Trek TOS episode. Very high quality.

It claimed 15 minutes to convert: It appeared to freeze at 99% but I let it sit. After about seven minutes at 99% it finished and offered to copy the file. The app produced a 270Mb MP4.

Oddly enough, the newest version of Mplayer (Nokia) won't play this (or other) MP4 files. The sound stutters badly, and the video displays as stills.

I have to say congrats, Nokia team! The video output was truly excellent, much better than I've been able to produce with tablet-encode. I'm going to play with mencoder this weekend and see it I can replicate the quality, but for Windows users this will be a fine tool.

BTW, the OS2008 media player still does not recognize standard H.264 video podcasts downloaded from NBC or CNN.

Jeff, thanks for the feedback report. I am assuming that the final file played ok on your N810?

Have you filed this as a bug in the Maemo Bugzilla?
