New iPods

Something drastically wrong there then.

Have you checked video dimensions and sound codec?

If you view it in Quicktime then choose Window/Movie Inspector or Movie Properties you'll be able to see what exactly is in the video.

Post back here with a screen grab or something...

Yeah, I reduced the size to 320x240, using AAC for sound at 128kbps.

EDIT: I think I know whats wrong, the original file I downloaded is about 157kbps for the video but the settings I got from the n95 blog said to use 1280kpbs which i've now dropped to 720, no wonder.

Will try again with sensible settings.

[matt]

Ah, the bit rate!

I'd be inclined to go for around the same as the source file. Especially given you're re-encoding.

eh!

1.2mb/s for watching on a mobile phone? That's some serious overkill...when I used to regularly do XviD encodes I'd rarely go over 800kb/s for 640px wide movies. I'd expect something around 600-700kb/s would be more thab adequate for your needs.

Yeah I know, I ended up encloding at 144 which gave me a file around 100MB, only problem now is when played on my phone it tells me it can't play the video only sound. aaarrrrghh. How are non-technical people ever able to watch video on mobile devices, i'm no technophobe and I can't get it to work?

[WiteWulf]

Hmm...I'm guessing the phone also has a minimum bitrate to keep the buffer full. Have a play around until you get the best results I'd suggest. 144 is *very* low bitrate, even for 320x240 using H264. Are you *sure* the original was only 157?

What tool are you using to do the transcoding with?

No it's not, that was Windoze not knowing how to count, it's actually 900 and something.

I'm using Super for the encoding...

[Jamie]

What I don't get though is that even encoding at 144 I got a file over 100MB, if 144 is really low how did Jimaroid manage to get watchable video from a file only 80MB for a 45 min programme?

You must be doing something wrong. I just used whatever ffmpeg thought was the best default and it turns out:

Code: Select all

  
  Duration: 00:42:10.3, start: 0.000000, bitrate: 277 kb/s
  Stream #0.0, 23.98 fps(r): Video: mpeg4, yuv420p, 480x320
  Stream #0.1: Audio: mp2, 48000 Hz, stereo, 64 kb/s

And the original for comparison:

Code: Select all

 Duration: 00:42:10.3, start: 0.000000, bitrate: 1157 kb/s
 Stream #0.0, 23.98 fps(r): Video: mpeg4, yuv420p, 624x352
 Stream #0.1: Audio: mp3, 48000 Hz, stereo, 112 kb/s

Cheers, it appears that even though nokia say the phone supports H.264 it actually doesn't because using the same bitrates and switching codecs to MP4 gave me a file that the phone would play.

I'll try your settings now, it seems you're using a lower bitrate for the audio which is probably the reason for the lower file size.

One last question before I bugger off out of this topic with my wildly off topic questions. Is there an easy way of splitting a video file up into smaller pieces, the phone doesn't support resume from previous position if you stop the video and quit the movie application?

So what are the estimated ship dates in Europe for the new iPod Touch?

down here the Apple Store is indicating 28th September, I've pre-ordered mine from a shop so I've no idea when it will show up.

I'm dying to get my hands on this now, I may have to go and find some video to encode in anticipation of it arriving, maybe I should do Live After Death again, or the original Rez-Cowgirl Neon video.

[Kemper_Boyd]

28th is the UK date. I looked in an Apple store last week and they had
none of the new ones in. I think nanos and the classic are showing up now.

[Jimaroid]

Yep, estimated delivery date from the Apple store is showing 1st-2nd October...

ARE WE THERE YET, STEVE?

Same in the US. If someone gets theirs before I do I'm going to sulk hard and long.

[Jimaroid]

This worldwide orchestration of Steve lovers into spufftaneous release is quite something. I'm aching in build up, I don't think my knees will be able to keep me standing on the day.
