i have difficulty in encoding videos to approriate iPod format

[epow0317]

my operation system is windows xp 32bit.
and i used megui(version 0.3.1.1051) in encoding videos.
also, encoding setting i used is [x264: Device-iPod].

but, when i excuted it thorugh the QuickTime,
it doesn't work at all.
it says Invalid Public Movie Atom was Found in the Movie.

i have went through this before.
the cause of this situation was Frame rate.
but, situation lately happend seems to be diffrent form previous that of it.

i'm wondering if you could solve this problem.
please, help me.
the details of encoded video are here.

Max bitrate has to be 1500, I'm fairly sure. Also, make sure the audio is AAC-LC, not AAC-HE

[Lyle_JP]

Your bitrate is double what you set the vbv_maxrate and vbv_bufsize to. It's a wonder it encoded. As I recall, vbv_bufsize should be set to 2000 and vbv_maxtrate needs to be set to 2500 (this works with any video iPod with the latest firmware). Bitrate is probably overkill at 1500. 1000 works on most material, with 1200 for bitrate-hungry stuff. Also, you can be at level 3, 1.3 is too low.

u said i should modify Max-bitrate.
so, i have tried to find anything concerned with it.
there's no textbox i could control about Max-bitrate.

but, Megui has both VBV Buffer Size and VBV Maximum Bitrate.
are they related to this situation?
how can i control the Max-Bitrate?

Please, Help me.
Oh! also, i'm not good at english.
so please, understand me.
thanks :-)

i tried what you said to me.
but, when i attempt to control VBV Maximum Bitrate to 2500.
Megui warned me "Sorry, the selected profile exceeds the AVC Level you have specified Maximum Bitrate is too high"

In fact, i encoded [the trailer of Twilight: New Moon] through the same profile.
but, it completely works in QuickTime.
why this situation affect to special case?
please, help me.

Why do you use the iPod profile instead of the iPod5.5 profile? The 5.5 profile supports a max of 1500 bitrate, but I'm not sure what the regular iPod profile can support.

I encode for iPod all the time, I'm not sure if I'm good at explaining though... I'll try...

1st I change the 5.5G profile to have a bitrate of 1500... For the audio profile I use Nero AAC: NDAAC - iPod - Good and change it to Constant Bitrate @ 128kps. (I also check the Apply Dynamic Range Compression box to increase the volume)

When making the Avisynth script, if the movie is animorphic I check the Clever anamorphic encoding to resize to mod 16. Crop. Resize down to 640 x ??? (as long as the first number is 640 you are ok). Do anything else you need to in the script (deinterlace, filters, etc...)

So back at the main screen of megui, make sure your avs is loaded, use the iPod 5.5G settings, load your audio and use the iPod Good settings.

Then I hit AutoEncode, select MP4, then in the Device drop down box I select iPod, then select No Target Size and finally click Queue...

After the encode is finished, I've discovered that MeGUI forgets to pass to mp4box the correct aspect ratio for anamorphic videos and so I end up re-muxing with YAMB to set the aspect ratio back to 16:9...

Anyway, thats just what I do to make them work.

I have in the past been able to add chapters and soft subtitles, but I've found that those only work with the iPod Touch/iPhone (and not on my iPod 5.5G)

@epow0317...start megui go to options>settings and check "Force Video File Extension for QT compatibility"...this will solve the QT "Invalid Public Movie Atom was Found in the Movie" problem...

Did you change the level to 3.0 from 1.3 like I suggested?

Here's the line I use for iPod videos. I get videos that, when played back and upscaled to HD on my PS3, look as good as the DVD source (and yes, they play back perfectly on iPods too):
--profile baseline --level 3 --preset fast --pass 2 --bitrate ???? --stats ".stats" --thread-input --deblock 0:0 --no-cabac --b-bias 0 --scenecut 40 --ref 1 --qpmin 16 --vbv-bufsize 2000 --vbv-maxrate 2500 --rc-lookahead 50 --aq-mode 1 --aq-strength 1.0 --merange 12 --me umh --subme 6 --partitions p8x8,b8x8,i4x4,p4x4 --no-8x8dct --trellis 0 --psy-rd 1.0:0 --no-mixed-refs --no-fast-pskip --output "output" "input"

It's essentially the iPod5.5g profile, but with some tweaks I added. The bitrate is source dependent, with reasonable values being anywhere from 800-1200 depending on the complexity of the source material. Movies with a lot of static shots, or night-time sequences require less; heavy noise, grain, and or movement require more. I just completed a 688x386 iPod video of "The Shining", which compressed perfectly at only 900 kbps.

i'm encoding video in the way you told me.
I guess it will be played completely.
Anyway, thank you for helping me.

i have just finished encoding video in the way you suggested me.
but, situation occured again...

what should i do?
should i change AVC Level to 3.0?
oh, my god..
it drives me crazy.
help!

Finally, i changed AVC Level to 3.0.
also, i changed Profile to iPod 5.5 Profile.
and now, i'm encoding video.

by the way, can AVC Level 3.0 be played on iPod Touch 1G?

what should i do..........

i encoded two video as a same way.
one is twilight new moon trailer.
the other is twilight movie.

trailer works perfectly, but twilight movie
doesn't work...

please, please, please help me.!!!!!!!!!!!!

-baseline 3.0, bitrate 1000, vbv buffer 1500, max bitrate 1500, Reference Frame 5

Perhaps,,,
Can QT really find out Invalid Movie Atom?
Profile doesn't contain anything that causes error.
oh, dear..

[b66pak]

@epow0317...man you did not do what i instruct you to do!!!

start megui go to options>settings and check "Force Video File Extension for QT compatibility"...this will solve the QT "Invalid Public Movie Atom was Found in the Movie" problem...

_

P.S. this is the proof:

--output "Twilight 720P.mp4" "Twilight 720P.avs"

why are you asking for help if you don't follow the instructions?
_

P.S.2 if you still have the .mp4 demux it to raw (using mp4box) then remux the .h264 to .mp4 again...this will solve the problem...

[proof]: http://hosting.ohseon.com/aemalf/proof.bmp

I've already done it before.
But, i think megui doesn't apply this option.

After i checked it, The commandline is still
"program --profile baseline --pass 2 --bitrate 1500 --stats ".stats" --level 1.3 --ref 5 --bframes 0 --no-cabac --subme 6 --trellis 0 --partitions p8x8,b8x8,i4x4,p4x4 --no-8x8dct --qpmin 16 --vbv-bufsize 768 --vbv-maxrate 768 --me umh --merange 32 --thread-input --output "output" "input" "

>> STILL output "output" "input"

Megui seems to ignore this option. what can i do..?
>> Should i do something special after i check it?
Should i upgrade megui to latest version ?
What version do you use?

Demux, and then Remux?
Ok! i'll try!

Thanks for your undying help!

it works great!
thanks!!!

[b66pak]

do this:

1. prepare the audio: it should be .aac, .mp4 or .m4a;
2. load the .avs script in megui;
3. select the desired iPod profile;
4. hit "autoencode" (make sure that options>settings>"Force Video File Extension for QT compatibility" is checked
5. select the bitrate or final size and check "add additional content";
6. add the audio;
7. start the queue!
