iPod video testing

All the applications mentioned ( except for QT pro ) use ffmpeg as the end conversion tool.

Stick to square pixels, keep you bitrate under 2500 ( video + audio + overhead ), and mpeg-4/aac.

A very simplified example...

ffmpeg -i <inputfile> -vcodec mpeg4 -b <bitrate> -r <framerate> -acodec aac -ab <audiobitrate> -f mov output.mov
 
Me Too

I'm going to be doing the same thing becuase i want pretty much all my videos on my ipod to be watchable on the screen but still look good on a TV. I tried to export an iMovie i had just made by going to expert settings > then ipod and I let it go while i was at work and i let it go overnight and it was barely half done in the morning. I think Apple needs to fix this problem becuase i tried it again and it still took too long i think and other people seem to be having the same problem. So far, i ripped a dvd and i ripped it as a .mp4 file at 480X368 and i used AAC audio. It should work on the ipod i'm not positive but it's basicaly all the specs of the maximum supported size and quality for .mp4's. That's just my 2 cents!

That's the $64,000 question right there... the info we all got before the 5G iPods became available is, it turns out, not really very accurate... hence all of the testing that people like snowmoon and myself have been performing.
 
As for what the videos look like on a tv- I should be recieving my vpod tomorow (wednesday Oct 19th) and will stop by tekserve (apple supply store in NYC) after work and pick up an av cable. by then, I hope i'm not the first one to put these two together, but if so I will post my results......
also, does the vpod come with a manual?

Ok updates...
We were able to get mpeg-4 with resolutions up to 640x360 to play back, this is far higher than the stated 480x480.

is the the rescaling for ipod nice (like photoshop bicubic or bilinear)
or yucky (just throwing away pixels) -- test with something like
like movie credits text. is interpolation quality better
for identical aspect ratio (480x360) material?

i know you just want to get it to work first, but much hair-pulling
can be saved by just using QT pro to pin down resolution/simple profile
.mp4 issues first, without bringing non-apple codecs to the fore ...

The biggest problem with QT Pro so far seems to be that it is PAINFULLY slow... I've heard others quote conversion times exceeding 24 hours. Plus, I don't know that it provides an option to convert DVDs to iPod-playable movie files (which is what I have been focusing on).
 
kinda redundant but...

since i can't use handbrake 0.7 beta3, will the mp4/aac encoding from handbrake 0.6 suffice? meaning, will it play on the new ipod? if somebody could check that quick, with a chapter of a DVD or something, that'd be great.

Perhaps this is not an ipod issue but a handbrake issue. It is a Beta of course. I would be curious to see if the older version of handbrake works. still dont have my pod so I cant test. anyone else?
 
I fully recommend that people who are not conversion geeks wait 1 week for everything to settle down some. Even then this software has always been "touchy" and can work on day and not the next, always test your output before doing a lot of work!

For us conversion geeks we are working hard to give you much more quality than iTMS is giving you. It's looking like 2x file size will prodice DVD like quality on playback, but I can't be positive till I have run some more tests and tested video out.

When I'm done I will have 2 settings... one where quality is more important than size ( but size is still a close second ) and the other that is optimized for watching on the iPod itself or when TV out is not a big deal.
 
For what its worth, I converted a .AVI file to a MP4 h.264 using ffmpegx and I could play it on QT, so after I finish class, I will try and export 'Movie to iPod', it should work. So anyone interested in converting .AVI files to watch on your iPod.. it works.

(Maybe I can even add it straight to my iPod without needing to do 'Movie to iPod' well see what happens when I get a chance to actually do it.)

interesting idea; i'll have to try that when i go home. earlier, i found that i can crop the picture to scale it down to 320x240 using the crop tool in handbrake 0.6. i'll let you know how it turns out, but i won't be able to test it on an ipod with video until next tuesday or wednesday...

With .avi files I have had success using only QT Pro to convert them to iPod format. However, you do have to have the .avi codec. (Link). It says its not Tiger compatible but I haven't had any problems. I've basically learned if you can get it to play in QT, you can convert it. It just takes a loooooooong time.

Ok, After I went back to my dorm, I successfully used the 'Movie to iPod' function to convert it to a .m4v, but when I added it to the iTunes Library, and try to drag it to my iPod, it says the format is not supported. This is kind of wierd because I just did a 'Movie to iPod' export. I don't understands whats wrong... it didn't work. I'll try exporting it again after I finish my chem class.

Thanks!! :cool: I'll try it out! I really need something that can convert .avi to an iPod format.
 
I am trying something new to see if 480x480 video might be possible under the iPod. People that I have been working with have been sent a PM!
